affirmative and negative agreement, negation, command

Affirmative Agreement

When indicating that one person pr thing does something and then adding that another does the same. Use the word so or too. To avoid needless repetition of words from the affirmative statement, use the conjunction and followed by a simple statement using so or too. The order of this statement will depend on whether so or too is used.

1.When a form of the verb be is used in the main clause, the same tense of the verb be is used in the simple statement that follows.

            Affirmative statement (be) + and + subject + verb (be) + too

                                                                       so + verb (be) + subject
Example:
I am beautiful. You are beautiful
- I am beautiful and you are too
- I am beautiful and so are you

2. When a compound verb (auxiliary + verb), for example, will go, should do, has done, have written, must examine, etc. occurs in the main clause, the auxiliary of the main verb is used in the simple statement, and the subject and verb must agree.

Affirmative statement + and + subject + auxiliary only + too

                                                           so + auxiliary only + subject 

Example:

They will work in the lab tomorrow. You will work in the lab tomorrow. 

- They will work in the lab tomorrow and you will too

- They will work in the lab tomorrow and so will you

3.When any verb except be appears without any auxiliaries in the main clause, the auxiliary do, does, or did is used in simple statement. The subject and verb must agree and the tense must be the same.

         Affirmative statement + and + subject + do, does, or did + too

         (single verb except be)                 so + do, does, or did + subject 

Example:

Jane goes to that school. My sister goes to school

 - Jane goes to school and my sister does too

 - Jane goes to school and so does my sister 

Negative Agreement

Either and Neither function in simple statements much like so and too in affirmative sentences. However, either and neither are used to indicate negative agreement. The same rules for auxiliaries, be and do, does, or did apply.

Negative statement + and + subject + negative auxiliary or be + either

                                                   neither + positive auxiliary + subject

Example:

I didn’t see Mary this morning. John didn’t see Mary this morning

 - I didn’t see Mary this morning and John didn’t either

 - I didn’t see Mary this morning and neither did John

  

Negation

To make a sentence negative, add the negative particle not after the auxiliary or verb be. If there is no auxiliary or be, add the appropriate form of do, does, or did and place in word not after that.

Example:

John is rich                              John is not rich

Mark has seen Bill                   Mark has not seen Bill

Commands

A command is an imperative statement. One person orders another to do something. It can be preceded by please. The understood subject is you. Use the simple form of the verb.

Example:

Close the door                                     leave the room

Please turn off the light                      Open your book
