Сравнительные степени прилагательных и наречий (Comparison) Модальные глаголы (Modal Verbs) Цепочки существительных (Атрибутивная, номинативная группа) (Chains of nouns)

1.
Определение
– это член
предложения,
указывающий
на признак
предмета и
отвечающий
на вопрос «какой?».
Оно относится
к существительному.
В английском
языке наиболее
типичными
являются атрибутивные
группы A+N
(прилагательное
+ существительное),
например, an
important
problem
– важная проблема.
Однако очень
распространёнными
являются номинативные
атрибутивные
группы, где
определение
выражено
существительным
N1+N2,
например, space
missions
– космические
полёты или
полёты в космос.


Трудность
номинативных
групп N1+N2
для перевода
заключается
в том, что нужно
уметь найти
основное слово
в цепочек
существительных
с тем, чтобы
предшествующие
ему слова перевести
как определения.
Случаи, когда
N1
эквивалентно
существительному
в именительном
падеже, например,
signal-generator
– (сигнал-генератор)
очень редки.
Зачастую даже
двухкомпонентные
атрибутивные
группы нужно
переводить
целым придаточным
предложением,
например, pay
pocket
– конверт, в
котором выдаётся
заработная
плата.


В
научно-технической
литературе
наиболее
употребительными
являются
двухкомпонентные
атрибутивные
группы типа
N1+N2.


Номинативные
атрибутивные
группы в технической
литературе
могут включать
до шести существительных.
При переводе
таких цепочек
существительных,
несущее большую
смысловую
нагрузку, ставится
на первое место.
Например, water
energy pressure – давление
за счёт энергии
воды.


На
уровне предложения
выделение
атрибутивных
групп облегчается
наличием ряда
признаков. Так
суффикс у основного
(последнего
в цепочке)
существительного
помогает найти
стоящие перед
ним определения.

2. В
атрибутивной
группе, независимо
от её количественного
состава, основным
существительным
является последнее
слово, а предшествующие
ему – определениями.

3.
Эквивалентном
атрибутивной
группы N1+N2
является
сочетание двух
существительных,
соединённых
предлогом «of»,
причём они
могут подвергаться
взаимной
трансформации,
например, the
structure
reliability
= the
reliability
of
the
structure
= надёжность
конструкции.

4.
В атрибутивных
группах типа
A+
N1+N2,
где А – прилагательное,
и N1+N2+N3
основным является
последнее
существительное,
а остальные
– определения
к нему.


Перевод
A+
N1+N2
может
совпадать с
порядком следования
слов в атрибутивной
группе, например:
narrow
vacuum
vessel
– узкий вакуумный
сосуд. Однако
во многих случаях
при переводе
A+
N1+N2
и N1+N2+N3
необходимо,
как правило,
сначала перевести
основное (последнее
существительное),
а затем – определения
к нему. Порядок
перевода слов
в атрибутивных
группах может
быть различным
и определяется
по смыслу, например:
Low
temperature
physics
– физика низких
температур.

5. Выделение
атрибутивной
группы N1+N2
облегчается
наличием различных
суффиксов
существительного
N2
(-er
(-or),
-ment,
-ion
(-tion,
-sion)),
например: We
compare
the
levels
of
machine
vibrations
with
biological
systems.

6. Наличие
явного
сказуемого
(is, are, was, were, have, had, has, must, can, may) –
облегчает
поиск
атрибутивной
группы
N1+N2,
выступающей
в
функции
подлежащего,
например:
Sound waves are analyzed by the computer every one-hundredth of a
second.

7. Атрибутивная
группа
N1+N2
может
входить
в
состав
подлежащего
и
вводиться
при
помощи
различных
предлогов
(of, at, in), например:
A new type of laser beam has been developed by Byelorussian
scientists, где,
N1+N2
/laser beam/,
стоящее
перед
явным
сказуемым
«has been developed», вводится
в
группу
подлежащего
при
помощи
предлога
“of” (новый
тип
лазерного
луча).

8. За
атрибутивной
группой подлежащего
N1+N2
может стоять
неявное сказуемое.
Оно может быть
выражено словом
без предлогов,
местоимений
и т.д., согласующимся
с подлежащим
по правилу
противоположности
окончания s,
или словом с
–ed,
например: Microwave
energy
enters
the
cavity
through
a
hole
in
the
wall.
Слово enters
согласуется
по правилу
противоположности
“s”
со словом energy
и образует пару
подлежащего-сказуемого
(energy
enters),
следовательно,
слово microwave
(N1)
является определением
к слову energy
(N2)
и переводится
«энергия микроволн».

9. Атрибутивная
группа N1+N2
может входить
в состав второстепенных
членов предложения
– определения,
дополнения,
обстоятельства
и находиться
в его правой
части после
сказуемого,
например: The
glue
is
already
used
in
the
production
of
car
tires,
где N1+N2
(car
tires)
входит в состав
предложного
дополнения.

Text:


The
first man-made satellite was launched on October 4, 1957. It
demonstrated to the whole world the boundless opportunities of our
country in science and technology. People everywhere in the world now
know the Russian world “Sputnik”.


It was
Juri Gagarin’s flight in 1961 that began an era of manned space
flights on orbital space stations.


The
Soviet Union did much in the exploration and use of outer space for
the benefit of man. Highly qualified specialists performed scientific
experiments aboard space stations. They used the latest automatic
instruments and computers in their work.



The
USSR made great contribution to extensive interna­tional
cooperation in space research and to the use of outer space for
peaceful purposes.



Some years ago
nine socialist countries adopted a
joint space research program.



The Soviet and
international crews performed a large number of astrophysical,
geophysical and other research experiments. Space
flights are no longer regarded as being experiments by brave people
or even by individual countries. The Intercosmos of the socialist
community countries proves the advantages of joint efforts.



The Soviet Union is also successfully cooperating in
space research with France, India, the USA and Sweden.



It pays great
attention to
the manned flights program which helps to solve a number of
scientific and applied economic problems.


Comparative Adjectives

When we talk
about 2 things, we can "compare" them. We can see if they
are the same or different. Perhaps they are the same in some ways and
different in other ways.


A       B


We
can use comparative adjectives to describe the differences. "A
is bigger
than B."


Formation of Comparative Adjectives

There are two
ways to form a comparative adjective:



short adjectives: add '-er'


long
adjectives: use 'more'













































Short adjectives




1-syllable adjectives



old, fast


2-syllable adjectives ending in -y



happy, easy

Normal rule:
add '-er'


old > older

Variation:
if the adjective ends in -e, just add -r


late > later

Variation:
if the adjective ends in consonant, vowel, consonant, double the
last consonant


big > bigger

Variation:
if the adjective ends in -y, change the -y to -i


happy > happier

Long adjectives




2-syllable adjectives not ending in -y



modern, pleasant


all adjectives of 3 or more syllables



expensive, intellectual

Normal rule: use 'more'



modern > more modernexpensive > more
expensive



Tip.
With some 2-syllable adjectives, we can use '-er' or
'more':



quiet > quieter/more quiet


clever >
cleverer/more clever


narrow >
narrower/more narrow


simple >
simpler/more simple


Exception!
The following adjectives have irregular forms:



good > better


well
(healthy) > better


bad >
worse


far
> farther/further


Use of Comparative Adjectives

We use
comparative adjectives when talking about 2 things (not 3 or 10 or
1,000,000 things, only 2 things).


Often, the
comparative adjective is followed by 'than'.


Look
at these examples:



John is 1m80. He is tall. But Chris is 1m85. He
is taller than
John.


America
is big. But Russia is bigger.


I
want to have a more powerful
computer.


Is
French more difficult
than English?


If we talk about
the two planets Earth and Mars, we can compare them like this:







































Earth



Mars


Diameter (km) 12,760 6,790

Mars is smaller
than Earth.


Distance from Sun (million km) 150 228

Mars is more
distant
from the Sun.


Length of day (hours) 24 25

A day on Mars
is slightly longer
than a day on Earth.


Moons 1 2

Mars has more
moons than Earth.


Surface temperature (°C) 22 -23

Mars is colder
than Earth.


Superlative Adjectives

Comparison
is between 2
things: "A is bigger than B."


A       B


But
the superlative
is the extreme between 3 or more
things. "A is the biggest."


A       B       C


Formation of Superlative Adjectives

As
with comparative adjectives, there are two ways to form a superlative
adjective
:



short adjectives: add '-est'


long
adjectives: use 'most'


We also usually
add 'the' at the beginning.













































Short adjectives


1-syllable adjectives old, fast
2-syllable adjectives ending in -y happy, easy

Normal rule:
add '-est'


old > the oldest

Variation:
if the adjective ends in -e, just add -st


late > the latest

Variation:
if the adjective ends in consonant, vowel, consonant, double the
last consonant


big > the biggest

Variation:
if the adjective ends in -y, change the -y to -i


happy > the happiest

Long adjectives


2-syllable adjectives not ending in -y modern, pleasant
all adjectives of 3 or more syllables expensive, intellectual

Normal rule: use 'most'



modern > the most modernexpensive >
the most expensive


Tip
With some 2-syllable adjectives, we can use '-est' or
'most':



quiet > the quietest/most quiet


clever
> the cleverest/most clever


narrow
> the narrowest/most narrow


simple
> the simplest/most simple


Exception!
The following adjectives have irregular forms:



good > the best


bad >
the worst


far
> the furthest


Use of Superlative Adjectives

We use a
superlative adjective to describe 1 thing in a group of 3 or more
things.


Look
at these examples:



John is 1m75. David is 1m80. Chris is 1m85. Chris
is the tallest.


America,
China and Russia are big countries. But Russia is the
biggest
.


Mount
Everest is the highest
mountain in the world.


If we talk about
the three planets Earth, Mars and Jupiter, we can use superlatives
like this:













































Earth



Mars



Jupiter


Diameter (km) 12,760 6,790 142,800

Jupiter is the biggest.


Distance from Sun (million km) 150 228 778

Jupiter is the
most distant
from the Sun.


Length of day (hours) 24 25 10

Jupiter has the
shortest
day.


Moons 1 2 16

Jupiter has the
most
moons.


Surface temperature (°C) 22 -23 -150

Jupiter is the coldest.



When we compare
one thing with itself, we do not use "the":



England is coldest
in winter. (not the coldest)


My
boss is most generous when we get a big order. (not
the most generous)


Comparison of
Adverbs

There
are 2 ways how the adverbs form their comparative and superlative.


1.
Adverbs in -ly
form their comparative and superlative with more
and
most
.
(But not early)


Could
you say that more
slowly
,
please?Tom can shoot the
most accurately.
You
will just have to get up earlier.


2.
Adverbs with the same form as adjectives form their comparative and
superlative with -er
and
-est.


Sarah
run the fastest.


Some
adverbs form their comparative and superlative irregularly.

































Positive



Comparative



Superlative


badly worse worst
well better best
little less least
far farther, further farthest, furthest
much more most

Comparison
as...as, less etc.


We
use as...as to
compare 2 things that are the same in the same way.I cannot do
crosswords as quickly as you.


Less
and least
are the opposites of more
and most.
The old man's son visits him less
often
nowadays.


We
can repeat a comparative after and
to talk about a change in something else.They went faster
and faster
down the hill.


We
use the+comparative to
talk about a change in one thing which causes a change in something
else.The more
you practise, the better you
will play.

Ten
sentences:


I
am not the tallest student in our group.


James
Hetfield plays electric guitar much better than I.


I
think that tomorrow it will be colder than today.


On
my girlfriend’s birthday I bought the most expensive present
I could afford.

10) Mice are smaller than
elephants.

Text(~1500
symbols):



The first
computers with their electronics filled more
room than
up-to-date computers do. Photographs of early computers show men and
women in business suits and laboratory coats standing in the middle
of a room surrounded by a U-shape machine. In reality, people
operating and developing the
first
computers did not wear suits. Air-conditioning was poorer
than
people needed and they dressed in T-shirts and tennis shoes.


The
development of the transistor in 1948 made it possible to build
smaller
electronic devices. Computers became smaller
and smaller
and in our days personal computer can easily be fitted on the desk.
Notebooks have less
size than
personal computers and they widely used by businessmen. For the
most pretentious
people engineers created a Pocket personal computer that can find
room in pocket. Pocket PC is the
smallest
PC, on the other hand, it is the
slowest
and the least
powerful than
other personal computers. For people who do not need features like
Infrared or Bluetooth connection or color display that offers Pocket
PC, Palm designed small electronic organizer. It has fewer
features and it is less
powerful than
Pocket PC, but it is also less
expensive.


Computer
designers are trying to create more
friendly
interface computer, because it is sold better.
The one of the
most important
factors is a noise uttered by computer. Nobody likes noise and people
are ready to pay more
to buy quieter
PC.


The
progress never stops and smaller,
more powerful and quieter computers
will appear soon.


Can, Could, Be able to

Can
and could
are modal auxiliary verbs. Be able to
uses the verb "to be" as a main verb. It is not an
auxiliary verb, but we look at it here for convenience.

Can

Can
is an auxiliary verb, a modal auxiliary verb. We use "can"
to:



talk about possibility and ability


make
requests


ask
for or give permission


Structure of Can

subject
+ can + main verb


The main verb is
always the bare infinitive (infinitive without "to").


































subject



auxiliary verb



main verb


+ I

can


play tennis.
- He

cannot


play tennis.

can't


?

Can


you play tennis?

Notice
that:



Can is
invariable. There is only one form of can.


The
main verb is always
the bare infinitive.


Use of Can
can: Possibility and Ability

We
use can to
talk about what is possible, what we are able or free to do:



She can
drive a car.


John

>can speak Spanish.


I
cannot
hear you. (I can't
hear you.)


Can
you hear me?


Normally,
we use can
for the present. But it is possible to use can
when we make present decisions about future ability.



Can you help me
with my homework? (present)


Sorry.
I'm busy today. But I can
help you tomorrow. (future)


can: Requests and Orders

We
often use can
in a question to ask somebody to do something. This is not a real
question - we do not really want to know if the person is able to do
something, we want them to do it! The use of can
in this way is informal (mainly between friends and family):



Can you make a
cup of coffee, please.


Can
you put the TV on.


Can
you come here a minute.


Can
you be quiet!


can: Permission

We
sometimes use can
to ask or give permission for something:



Can I smoke in
this room?


You
can't
smoke here, but you can
smoke in the garden.


(Note
that we also use could, may, might for permission. The use of can
for permission is informal.)


Could

Could
is an auxiliary verb, a modal auxiliary verb. We use "could"
to:



talk about past possibility or ability


make
requests


Structure of Could

subject
+ could + main verb


The main verb is
always the bare infinitive (infinitive without "to").


































subject



auxiliary verb



main verb


+ My grandmother

could


speak Japanese.
- She

could not


speak Chinese.

couldn't


?

Could


your grandmother speak Japanese?

Notice
that:



Could is
invariable. There is only one form of could.


The
main verb is always
the bare infinitive.


Use of Could
could: Past Possibility or Ability

We
use could
to talk about what was possible in the past, what we were able or
free to do:



I could
swim when I was 5 years old.


My
grandmother could
speak seven languages.


When
we arrived home, we could not
open the door. (...couldn't open the door.)


Could
you understand what he was saying?


We
use could
(positive) and couldn't
(negative) for general ability in the past. But when we talk about
one special occasion in the past, we use be
able
(positive) and couldn't
(negative). Look at these examples:





















Past



General



Specific Occasion


+

My grandmother
could
speak Spanish.



A man fell into
the river yesterday. The police were
able
to save him.


-

My grandmother
couldn't
speak Spanish.



A man fell into
the river yesterday. The police couldn't
save him.



could: Requests

We
often use could
in a question to ask somebody to do something. The use of could
in this way is fairly polite (formal):



Could you tell
me where the bank is, please?


Could
you send me a catalogue, please?


Be able to

Although
we look at be able to
here, it is not
a modal verb. It is simply the verb "to be" plus an
adjective (able) followed by the infinitive. We look at "be able
to" here because we sometimes use it instead of "can"
and "could". We use "be able to":



to talk about ability


Structure of Be able to

The
structure of be able to
is:


subject
+ be + able + infinitive


































subject



bemain
verb



ableadjective



infinitive


+ I

am



able



to drive.


- She

is not



able



to drive.



isn't


?

Are


you

able



to drive?



Notice
that be able to
is possible in all tenses, for example:



I was able to
drive...


I
will be able to
drive...


I
have been able to
drive...


Notice
too that be able to
has an infinitive form:



I would like to be
able to
speak Chinese.


Use of Be able to
be able to: ability

We
use be able to
to express ability. "Able" is an adjective meaning: having
the power, skill or means to do something. If we say "I am
able to
swim", it is like saying
"I can
swim". We sometimes use "be able to" instead of "can"
or "could" for ability. "Be able to" is possible
in all tenses—but "can" is possible only in the
present and "could" is possible only in the past for
ability. In addition, "can" and "could" have no
infinitive form. So we use "be able to" when we want to use
other tenses or the infinitive. Look at these examples:



I have been able to
swim since I was five. (present perfect)


You
will be able to
speak perfect English very soon. (future simple)


I
would like to be able to
fly an airplane. (infinitive)


Have To (objective obligation)

We
often use have to
to say that something is obligatory, for example:



Children have to go to school.


Structure of Have To

"Have
to" is often grouped with modal auxiliary verbs for convenience,
but in fact it is not
a modal verb. It is not even an auxiliary verb. In the "have to"
structure, "have" is a main
verb
. The structure is:


subject
+ auxiliary verb + have + infinitive (with "to")


Look at these
examples in the simple tense:



































subject



auxiliary verb



main verb "have"



infinitive (with "to")


+ She

has



to
work.


- I do not

have



to
see


the doctor.
? Did you

have



to
go


to school?

Use of Have To

In
general, "have to" expresses impersonal
obligation. The subject of "have to" is obliged or forced
to act by a separate, external power (for example, the Law or school
rules). "Have to" is objective. Look at these
examples:



In France, you have
to
drive on the right.


In
England, most schoolchildren have to
wear a uniform.


John
has to
wear a tie at work.


In each of the
above cases, the obligation is not the subject's opinion or idea. The
obligation is imposed from outside.


We
can use "have to" in all
tenses
, and also with modal
auxiliaries. We conjugate it just like any other main verb. Here are
some examples:



























































subject



auxiliary verb



main verb "have"



infinitive


past simple I

had



to work


yesterday.
present simple I

have



to work


today.
future simple I will

have



to work


tomorrow.
present continuous She is

having



to wait.


present perfect We have

had



to change


the time.
modal (may) They may

have



to do


it again.

Must (subjective obligation)

We
often use must
to say that something is essential or necessary, for example:



I must go.


Structure of Must

"Must"
is a modal auxiliary verb. It is followed by a main verb. The
structure is:


subject
+ must + main verb


The main verb is
the base verb (infinitive without "to").


Look
at these examples:



























subject



auxiliary
verb"must"



main verb


I

must



go


home.
You

must



visit


us.
We

must



stop


now.
Use of Must

In
general, "must" expresses personal
obligation. "Must" expresses what the speaker
thinks is necessary. "Must" is subjective.
Look at these examples:



I must stop smoking.


You
must
visit us soon.


He
must work harder.


In each of the
above cases, the "obligation" is the opinion or idea of the
person speaking. In fact, it is not a real obligation. It is not
imposed from outside.


We
can use "must" to talk about the present
or the future.
Look at these examples:



I must go now. (present)


I
must call my mother tomorrow. (future)


There
is no past tense
for "must". We use "have to" to talk about the
past.

Must Not (prohibition)

We
use must not
to say that something is not permitted or allowed, for example:



Passengers must not talk to the driver.


Structure of Must Not

"Must"
is an auxiliary verb.
It is followed by a main verb.
The structure for "Must Not" is:



Subject + "Must Not" + Main Verb


The Main Verb is
the base verb (infinitive without "to").


"Must Not"
is often contracted to "mustn't".


Look
at these examples:



























subject



auxiliary "Must"
+ "Not"



main verb


I

mustn't



forget


my keys.
You

mustn't



disturb


him.
Students

must not



be


late.

NB:
like all auxiliary verbs, "must" cannot
be followed by an infinitive. So, we say:



You mustn't arrive late. (not
You mustn't to arrive late.)


Use of Must Not

"Must
Not" expresses prohibition - something that is not
permitted, not allowed
. The prohibition
can be subjective (the speaker's opinion) or objective (a real law or
rule). Look at these examples:



I mustn't eat so much sugar. (subjective)


You
mustn't watch so much television. (subjective)


Students
must not leave bicycles here. (objective)


Policemen
must not drink on duty. (objective)


We
use "Must Not" to talk about the present
or the future:



Visitors must not smoke. (present)


I
mustn't forget Tara's birthday. (future)


We
cannot use "Must Not" for the past.
We use another structure to talk about the past, for example:



We were not allowed to enter.


I couldn't park
outside the shop.


Shall and Will

People
may sometimes tell you that there is no difference between shall
and will,
or even that today nobody uses shall
(except in offers such as "Shall I call a taxi?"). This is
not really true. The difference between shall
and will
is often hidden by the fact that we usually contract them in speaking
with 'll.
But the difference does exist.


The
truth is that there are two
conjugations for the verb will:



















































1st
Conjugation (objective, simple statement of fact)




Person



Verb



Example



Contraction


Singular I shall I shall be in London tomorrow. I'll
you will You will see a large building on the left. You'll

It is true that
this difference is not universally recognized. However, let those who
make assertions such as "Americans never use 'shall'"
peruse a good American English dictionary, or many American legal
documents, which often contain phrases such as:



Each party shall
give one month's notice in writing in the event of termination.


Note that
exactly the same rule applies in the case of should and would. It is
perfectly normal, and somewhat more elegant, to write, for example:



I should be
grateful if you would
kindly send me your latest catalogue.

Combinatorial
mathematics.


Specialists
in a broad range of fields have
to deal with
problems that involve combinations made up of letters, numbers or any
other objects.



The field of mathematics that studies
problems of how many different combinations can
be built out of a specific number of objects is called combinatorial
mathematics (combinatorics).



This branch of mathematics has its
origin in the 16th
century, in the gambling games that played such a large part in high
society in those times. These games gave the initial impetus to
develop combinatorial mathematics and the theory of probability.



Italian and
French mathematicians were the first to enumerate the various
combinations achieved in games of dice. Further advances in the
theory of combinations were connected with the names of German
scientists.



In recent years combinatorial
mathematics has seen extensive developments associated with grater
interest in problems of discrete mathematics. Combinatorial methods
can
be employed in solving transport problems, in particular scheduling;
the scheduling of production facilities and of the sale of goods.
Links have been established between combinatorics and problems of
linear programming, statistics, etc. Combinatorial methods are used
in coding and decoding and in the solution of other problems of
information theory.


The
combinatorial approach also plays a significant role in purely
mathematical problems such as the theory of groups and their
representations, in the study of the main principles of geometry,
some branches of algebra, etc.

Probability.



Probability is a mathematical
expression of the likelihood of an event. Every probability is a
fraction. The largest probability can
be 1. The smallest probability can
be is 0, meaning that it’s something that cannot
happen. You can
find the probability that something will
not happen by
subtracting the probability that it will
happen from 1. For example, if the weatherman tells you that there is
a 0.3 probability of rain today, then there must
be a 0.7 probability that it won’t
rain.
