Past and future

Past
We use past to talk about things that were done in the past, and for doing so, there are three different ways that are:
* Adding “d or ed” at the end of the verb.(Simple past)
* Usingthe verb “to be” in past plus the “ing” at the end of the verb.(Past progressive)
* Changing completely the verb.
For example:
1. I worked very late at night last week.
2. He was fishingon Sunday.
3. Paul bought a wallet last night.

Future
We use the auxiliary will to talk about things that might happen in the future.
The correct form for making a sentence in English infuture is:
Subject + will + verb + adverb of time.
For example:
1. I will travel to Brasil next year.
2. Ann will look for a job next week.

This form indicates that an action was continuously ongoing. Byinserting not before the main verb a negation is achieved. Example: He was not going to church. A question is formed by fronting the simple past form of to be as in Was he going?.
* The emphatic past isformed by using the auxiliary verb "to do" and the uninflected main verb, (I did walk, He did walk). This emphasizes the idea communicated and can be used to remove doubt or preempt objection on the...
