[B][SIZE="4"][COLOR="Green"]Might or May[/COLOR][/SIZE][/B]

[B]People often confuse [U]may have[/U] and [U]might have[/U].

[U]May have[/U] should be used only when you are not sure whether or not something happened. If you want to say that at some time in the past it was possible for something to happen but in fact it did not, use [U]might have[/U].

An accident in which two people may have drowned happened in a village yesterday.

This sentence implies that you do not know whether the people are alive or dead. If you say [U]two people might have drowned[/U] you are implying that they survived, although the accident could in other circumstances have led to their deaths. [/B]

[B][SIZE="4"][COLOR="Green"]Which or That[/COLOR][/SIZE][/B]
[B]
What is the difference between [U]which [/U](or [U]who[/U]) and [U]that[/U]? How can you tell which one to use?

The basic question is whether you or the person you are talking to already know what it is that you are talking about. In the sentence:

I've lost the book that I was reading yesterday.

[U]That [/U]introduces information that the listener needs in order to know what book is being talked about.

[U]You can also say:[/U]

I've lost the book which I was reading yesterday.

In this sentence:

This book, which I bought yesterday, is very interesting.

[U]Which [/U]tells the listener something new about a book that has already been identified.

You shouldn't use [U]that [/U]in sentences of this kind.[/B]

[B][SIZE="4"][COLOR="Green"]Possessives[/COLOR][/SIZE][/B]

[B]To form a possessive from a singular noun, add an apostrophe followed by [U]s[/U]: the girl's book.

Add an apostrophe to plurals ending in [U]s[/U]: the girls’ books.

If a plural noun does not end in [U]s[/U], add an apostrophe followed by [U]s[/U]: the children's toys.

Also add an apostrophe to a name ending in -[U]es [/U]that is pronounced like the word [U]is[/U]: Moses' mother[/B]

[B][SIZE="4"][COLOR="Green"]Equally[/COLOR][/SIZE][/B]

[B]Don't say [U]equally as[/U].

This model is equally as effective. This sentence is a wrong one.

You can use either [U]equally [/U]or as on its own.

In sentences such as [U]My new car is just as good as the old one[/U] where two nouns are compared, you could replace [U]just as with as[/U], but it would be wrong to use [U]equally[/U]. [/B]

[B][SIZE="4"][COLOR="Green"]Contraction[/COLOR][/SIZE][/B]

[B]In words such as [U]isn't[/U], [U]I'm[/U] or [U]don't[/U], the apostrophe indicates that one or more letters have been left out.

[U]It's[/U] is the contracted form of [U]It is[/U] or [U]It has[/U] : not the possessive of it. The possessive is its with no apostrophe.

[U]So you should say:[/U]

It's a lovely day

Or

It's been a lovely day.

The dog is in its kennel. – This sentence is a wrong one.

[U]You’re[/U] is a contraction of [U]You are[/U]. The possessive is [U]your[/U].

You're my best friend. --- This is a right sentence.

Your my best friend. --- This is a wrong sentence.

Where is your friend? --- This is a right sentence.

Where is you’re friend? --- This is a wrong sentence.
[/B]

[B][SIZE="4"][COLOR="Green"]This or These [/COLOR][/SIZE][/B]

[B]A common mistake is to use the expression [U]These kind[/U] or [U]These sort[/U] as in the following sentence.

These sort of situations are always difficult.

The correct forms are:

This kind of situation…

And

These kinds of situations …

You could say either:

This kind of situation is difficult.

Or

These kinds of situations are difficult.

A more formal expression is:

Situations of this kind… [/B]

[B][SIZE="4"][COLOR="Green"]Sounds Like[/COLOR][/SIZE][/B]

[B][U]Sometimes a word sounds as though it contains another familiar word:[/U]

There is no cocoa in a coconut.

Bated breath has nothing to do with bait.

Corridor is not related to door.

Sacrilege has the i first and the e second, unlike religion.

Abseiling is quite different from sailing.

[U]Sometimes it is just part of another word that causes a mistake:[/U]

Privilege has no [U]d[/U], unlike, e.g., knowledge.

Attach and detach end in -[U]ach[/U], not -[U]atch[/U], unlike dispatch.

A protuberance is something that protrudes; but it has no [U]r [/U]after the [U]t[/U].

Dissect has a double [U]s[/U], though bisect has only one.

Psychedelic has an [U]e [/U]after psych, unlike psychology.[/B]

[B][SIZE="4"][COLOR="Green"]Adverbs[/COLOR][/SIZE][/B]

[B]The normal way to form an adverb is to add -[U]ly [/U]as in stupidly, publicly or humorously. However, there are exceptions:

If the word ends in -[U]ll[/U], add -[U]y [/U](e.g. fully).

For words of more than one syllable that end in -[U]y[/U], remove the -y and add -[U]ily [/U](e.g. happily).

Most single-syllable words ending in -[U]y [/U]are regular, except for daily and gaily. [/B]

[B][SIZE="4"][COLOR="Green"]Paired Words[/COLOR][/SIZE][/B]

[B]When you use pairs like [U]both [/U]. . . [U]and, not only[/U] . . . [U]but also[/U] or [U]neither [/U]. . . [U]nor[/U], make sure that each word in the pair is in the right place. The two words should introduce symmetrical structures.

[U]Example:[/U]

We met both at home and at work. --- This sentence is a right one.

We met both at home and work. --- This sentence is a wrong one.

Strictly speaking, you should say either one of the following two sentences.

He looked neither to right nor to left.

Or

He looked to neither right nor left.

But the following sentence is a wrong one.

He looked neither to right nor left.

Similarly, a sentence like the following one is a wrong expression.

She is not only a talented singer but writes her own songs. --- This sentence is a wrong one.

You could rewrite it as either one of the following two sentences.

She is not only a talented singer but also a composer.

Or

She not only sings but also writes her own songs.[/B]

control on grammar
 

Bro can you give me some idea for how to have a control on sentences. mean while having many problems attempting paragraphs, where grammar is not much supportive.
just give a view of understanding on how to understand grammar,example how to put commas.
In nut shall, give me an idea to improve English grammar in some days to bring improvement in my writing.
