English tenses are verb forms, and different tenses are used to express different times and ways.

It is a verb form that expresses behavior, action and state under various time conditions. So when we say tense structure, we mean the verb form corresponding to tense.

Mutual transformation of several common tenses

Several tenses in English can be transformed into each other in some cases. The following are several common forms of conversion:

XI。 Conversion between simple past tense and present perfect tense

In the present perfect tense, progressive verbs can be used with adverbials indicating a period of time, but instantaneous verbs can't. But other expressions can also be used: ① the sentence pattern of "a period of time+before" in the general past tense uses instantaneous verbs; ② Instantaneous verbs can be converted into corresponding continuous verbs and phrases to be used for a period of time; ③ Instantaneous verbs are used in the sentence pattern of "It is+a period time+since+simple past tense", which means "it's been a while since+simple past tense". Please see:

A.he joined the league two years ago.

B.he has been in the league for two years.

C. he has been in the league for two years.

D. Two years have passed since he joined the League.

Twelve, the conversion between the simple present tense and the present continuous tense

In the simple present tense, at with a noun means "in a certain state", such as at work, at school, etc. This phrase can be converted into tense. Please see:

Peter is working, but Mike is playing.

Peter is working, but Mike is playing.

Thirteen, the conversion between the present continuous tense and the general future tense

In the present continuous tense, verbs such as go go, come, leave, start and arrive are often used with adverbials indicating future time to indicate actions that will happen. I'm coming, mom! I'm coming, mom! Please see:

The train will leave soon.
