Use the question mark:
1. At the end of all direct questions
2. Do not use the question mark for reported questions
General notes:
1. Don't forget to place a question mark at the end of long sentences that contain a question
2. Sometimes a question mark can be placed within a sentence
The period (known as a full stop in British English) is probably the simplest of the punctuation marks to use.
You use it like a knife to cut the sentences to the required length. Generally, you can break up the sentences using the full stop at the end of a logical and complete thought that looks and sounds right to you. Use the full stop
1. to mark the end of a sentence which is not a question or an exclamation.
2. to indicate an abbreviation
Note: Dr and Mr and Mrs and Ms do not take a full stop nor do most abbreviations taken from the first capital letters such as MA Phd CNN
3. special case - three dots
Often you will see a sentence concluding with three dots. This indicates that only part of the sentence or text has been quoted or that it is being left up to the reader to complete the rest of the sentence.
3. fullstop after a single word
Sometimes a single word can form the sentence. In this case you place a fullstop after the word as you would in any other sentence.
Note: This is often the case when the subject is understood as in a greeting or a command such as "Stop."
You use punctuation marks to structure and organise your writing. The most common of these are the period (or full stop in British English), the comma, the exclamation mark, the question mark, thecolon and semi-colon, the quote, the apostrophe, the hyphen and dash, and parentheses and brackets. Capital letters are also used to help us organise meaning and to structure the sense of our writing.
You can quickly see why punctuation is important if you try and read this sentence which has no punctuation at all:
perhaps you dont always need to use commas periods colons etc to make sentences clear when i am in a hurry tired cold lazy or angry i sometimes leave out punctuation marks grammar is stupid i can write without it and dont need it my uncle Harry once said he was not very clever and i never understood a word he wrote to me i think ill learn some punctuation not too much enough to write to Uncle Harry he needs some help
Now let's see if punctuating it makes a difference!
Perhaps you don't always need to use commas, periods, colons etc. to make sentences clear. When I am in a hurry, tired, cold, lazy, or angry I sometimes leave out punctuation marks.
"Grammar is stupid! I can write without it and don't need it." my uncle Harry once said. He was not very clever and I never understood a word he wrote to me. I think I'll learn some punctuation - not too much, enough to write to Uncle Harry. He needs some help!
Use the punctuation section to learn how to make your English clearer and better organised.
There are often prepositions in relative clauses, and the relative pronoun is the object of the preposition. This means that the preposition can sometimes be omitted.
The preposition is normally placed at the end of the relative clause:
In formal or written English, the preposition is often placed before the relative pronoun, and in this case the pronoun cannot be omitted:
However, this is unusual in spoken English.
The information in these clauses is not essential. It tells us more about someone or something, but it does not help us to identify them or it.

Non-defining relative clauses are always separated from the rest of the sentence by commas. The commas have a similar function to brackets:
Relative pronouns in non-defining clauses
Person | Thing | Place | |
Subject | who | which | |
Object | who/whom | which | where |
Possessive | whose |
This pattern is often used in spoken English, but in written or formal English you can also put the preposition before the pronoun: e.g. Stratford-on-Avon, about which many people have written is Shakespeare's birthplace.
Person | Thing | |
all of | + whom | + which |
any of | + whom | + which |
(a) few of | + whom | + which |
both of | + whom | + which |
each of | + whom | + which |
either of | + whom | + which |
half of | + whom | + which |
many of | + whom | + which |
most of | + whom | + which |
much of | + whom | + which |
none of | + whom | + which |
one of | + whom | + which |
two of etc... | + whom | + which |
