regular verb tenses

Most regular verbs form their past tense by adding -ed to the present-tense
form of the verb. Examples of this include walked, talked, and recalled.
If a regular verb ends in ‘‘e,’’ as in bathe or wave, simply add ‘‘d’’ to form
the past tense.

In addition to the present (expresses action that is occurring now) tense,
as in, ‘‘We remember that story,’’ and the past (expresses action that has
already happened) tense, as in, ‘‘We remembered that story,’’ there are
other verb tenses that you should know. Following are definitions and some
examples of these additional verb tenses:
Present Perfect: expresses action that was completed at some other time, or
action that started in the past and continues now. Add has or have to the past
participle form of the verb to make the present perfect.
I have climbed that small mountain every weekend since last April.
Past Perfect: expresses action that happened before another past action.
Add had to the past participle form of the verb.
We had walked up that hill before they did.
Future: expresses action that will happen in the future.
I will walk with you on Tuesday.
Future Perfect: expresses action that will be completed by a given time in
the future. Add shall have or will have to the past participle.
I will have walked to school by then.
