Grammar point


Dear Students,
Here are some GRAMMAR POINTS for you.
They will help you to review basic English grammar rules and to translate the texts. 
Read carefully and do the exercises below. 

GRAMMAR SECTION I:
Subject and Verb Agreement

  MEANING   

Subject verb agreement simply means the subject and verb must agree in number. This means both need to be singular or both need to be plural. If the subject is singular, the verb must be singular too. If the subject is plural, the verb must also be plural. When the subject of the sentence is composed of two or more nouns or pronouns connected by and, use a plural verb.

10 rules of Subject Verb Agreement

Rules
Explanations
Examples
Rule 1
The subject and verb must agree in number: both must be singular, or both must be plural.

Mr. Kent, accompanied by his business partners, is arriving tonight at the Chingis Khan airport. (Singular) Overnight guests of Russia need to ensure the main entrance locked at all times. (Plural)
Rule 2
The number of the subject (singular or plural) is not changed by words (or a phrase) that come in between the subject and the verb.
One of the boxes in the factory is open. Here the subject “one” and the verb are both singular.

Rule 3
Some subjects always take a singular verb even though the meaning may seem plural.
Someone in the factory was hurt.
Rule 4
The following words may be singular or plural, depending upon their use in a sentence: some, any, all, most etc.
Most of the news is good. (Singular) Most of the flowers were yellow.
Rule 5
Subjects joined by “and” are plural. Subjects joined by “or” or “Nor” take a verb that agrees with the last subject.
Bob and George are leaving. Neither Bob nor George is leaving.
Rule 6
“There” and “here” are never subjects. In sentences that begin with these words, the subject is usually found later on in the sentence.
There were five books on the shelf. (were, agrees with the subject “book”)

Rule 7
Collective nouns may be singular or plural, depending on their use in the sentence. 

The orchestra is playing a hit song. (Orchestra is considered as one unit—singular) The orchestras were asked to give their musical backgrounds. (Orchestra is considered as separate units-plural)
Rule 8
Some nouns, while plural in form, are actually singular in meaning.
Mathematics is (not are) an easy subject for some people.
Rule 9
“Doesn’t” is a contraction of “does not” and should be used only with a singular subject. “Don’t” is a contraction of “do not” and should be used only with a plural subject. 
He doesn’t (does not) like it.
Rule 10
Nouns such as ‘civics’, ‘mathematics’, ‘dollars’, and ‘news’ require singular verbs.
million dollars is needed to renovate that building.

GRAMMAR SECTION II:                                         
The Passive Voice

  MEANING   

The passive form of a verb is used frequently in classifying and in all scientific writing.  This is because the emphasis in science is usually on the action not on the person performing the action. A sentence is active if the subject performs the action. It is passive if the subject receives the action.

Formula for a passive sentence.

Active Voice
Subject + Infinitive + Object
Scientists classify mercury as a metal. 
Passive Voice
Subject + to be + Past Participle + by object
Mercury   is   classified as a metal (by scientists). 

If the action is in the present, use the present form of the verb to be is if the subject is singular, are if the subject is plural. If the action is in the past, use the past tense of the verb to be: was or were. When there is a modal like: can or must, use can be or must be. In the example above, the by-phrase (by scientists) is not used because it is understood. Here are some active sentences and their corresponding passive forms.

Active
Passive

We use lasers in the place of needles in compact disk recordings.
Lasers are used in the place of in needles in compact disk recordings.   
They discovered diamonds in South Africa in the nineteenth century.
Diamonds were discovered in South Africa in the nineteenth century.

GRAMMAR SECTION IV:
Sentence Structure

  MEANING   

Sentence is a set of words that are grammatically linked and complete in itself, typically containing a subject and predicate, conveying a statement, question, exclamation, or command, and consisting of an independent clause and sometimes one or more dependent clauses.

Types of Sentence Structure

Sentence Type
Examples
Simple sentences have one independent clause.
David drives carefully to work in the morning.

Compound sentences have at least two independent clauses.
I was born in the United States, yet I consider myself Mongolian.
Complex sentences have one independent clause and at least one dependent clause.
Whenever he was lonely, Lance called his mother.
Compound-complex sentences have at least two independent clauses and at least one dependent clause.
Jim doesn’t drink beer because he has a gluten allergy, so he tends to drink wine most weekends.


Parts of Sentence Structures

A clause is a part of the sentence that contains a verb. A typical clause consists of a subject and a predicate, the latter typically a verb phrase, verb with any objects and other modifiers. There are two main types of clauses:
·        Independent clause- (also known as a main clause) is a clause that forms a complete, independent thought. It can stand alone as a sentence. A single independent clause is known as a simple sentence. It contains a subject and a predicate, each of which can have modifiers.
For example: He went to the library.
·        Dependent clause- (also known as a subordinate clause) is a clause that relies on the information from an independent clause to form a complete, logical thought. It has a subject and a predicate; but it can’t be a sentence. It provides extra details about the independent clause, and it doesn’t make sense on its own.  
For example: After he went to the library
            There are three types of dependent clauses:
·        Noun clauses: They are used as Nouns.
·        Adjective clauses: They describe any noun or pronoun in the sentences.
·        Adverbial clauses: They are used as adverbs.

conjunction is a word in a sentence that connects other words, phrases and clauses. Conjunctions are a big part of compound, complex, and compound-complex sentences. Conjunctions are important because they let us combine information, but still keep ideas separate so that they are easy to understand.

·        If two clauses are connected with a coordinating conjunction, it is a compound sentence.
·        If two clauses are connected with a subordinating conjunction, it is a complex sentence.


Coordinating conjunctions:

Conj.
Uses

Examples
for
Explains reason or purpose (just like "because")
I go to the park every Sunday, for I long to see his face.
and
Adds one thing to another
I like to read, and I write faithfully in my journal every night.
nor
Used to present an alternative negative idea to an already stated negative idea
I neither love nor hate to watch TV.

but
Shows contrast
Television is a wonderful escape, but it interferes with my writing.
or
Presents an alternative or a choice
Would you rather read a book or watch a good TV show?
yet
Introduces a contrasting idea that follows the preceding idea logically (similar to "but")
I always take a book to the beach, yet I never seem to turn a single page.
so
Indicates effect, result or consequence
I like to read, so my grammar is always on-point.

Subordinating conjunctions:

Subordinators

Examples
Noun clauses
what, where, why, how, when, who, whom, which, whose, whether, that, if

GRAMMAR SECTION V:
Preposition Combinations

  MEANING   

Noun, Verb and Adjective + Preposition Combinations
Prepositions and the rules concerning their usage can be confusing to learners of English as a second language. Basically, prepositions are connecting words that join objects to other parts of sentences. Preposition choice is determined by the noun, verb, adjective or particle which precedes it.

Noun + Preposition Combinations
English has many examples of prepositions coming after nouns. In such cases, the prepositions are often followed by a phrase containing a noun, as in example (a) below. They can also be followed by a noun, as in example (b), or an -ing verb, as in example (c).

(a) Scientists at the research institute think they are close to finding a solution to the problem.
(b) Everyone was surprised by his lack of concern.
(c) We need to call an expert at plumbing as soon as possible.

Here are a few more nouns and prepositions which are used together:

the use of          a solution to                  influence on                  evidence of
the cost of         an increase in               a possibility of              danger of
the price of       a reason for                  a supply of                    a method of
a lack of           belief in                        the cause of                   difficulty with

Verb + Preposition Combinations
Many English prepositions also follow verbs. Sometimes they introduce a phrase that contains a noun, as in example (a). They can also introduce a noun, as in example (b), or an -ing verb, as in example (c).

(a) I don't know how long we can depend on his generosity. He has already done so much for us.
(b) Many of the town's residents relied on neighbours for help during the flood.
(c) She believes in helping people who are less fortunate than her.

Here are some other verbs and prepositions that are used together:


I insist on . . .   
He can deal with . . .
This can result in . . .    
Do you plan on . . .
We belong to . . .          
This could lead to . . .
My answer will depend on . . .  
You can rely on . . .
They fight for . . .         
We fight against . . .
We contribute to . . .     
I believe in . . .


Adjective + Preposition Combinations
English also has many instances of prepositions coming after adjectives. In many cases, the prepositions precede phrases containing nouns, as in example (a), or pronouns, as in example (b). It is also possible for the prepositions to precede an -ing verb, as in (c).
(a) I was amazed at all the improvements.
(b) We were all shocked by his behaviour.
(c) Because the exam was more difficult than I expected, I'm worried about passing.
Here are some more adjectives, verbs and prepositions that are used together:
