There are practical examples in many grammar books, just look at them more, it's not just a sentence or two sentences that you can practice, it's good to practice more.

The English tenses that are mainly studied in junior high school:

2. The general past tense, the action or state that occurred at a certain time in the past, the habitual and regular action or behavior in the past;

3. The present continuous tense indicates the ongoing actions and behaviors at the present stage or when speaking;

4. In the past continuous tense, it means that the act or action that is taking place or being carried out at a certain time or time is carried out by the person who is spreading the width;

5. In the present perfect tense, the impact or result of an action that has occurred or has been completed in the past on the present, or an action or state that has begun in the past and continues to the present;

Eight times and how to use.

1) Simple present tense denotes an action or state of being that occurs frequently or habitually at this stage, or states the characteristics of the subject.

2) Simple Past Tense Denotes an action or state that took place at a certain time in the past, which may be one-time or may be frequent.

3) Simple future tense denotes an action or state that happens at a certain time or often in the future.

4) Present Continuous Tense The present continuous tense signifies an action that is going on right now or an action that is happening at this stage and is not necessarily happening at the moment.

5) Past Continuous Tense The past continuous tense denotes an ongoing action at a certain moment or stage in the past.

6) Present Perfect Tense The present perfect tense denotes an action that took place in the past and still has an impact on the present, or an action that began in the past and continues until now, and may even continue.

7) Past Perfect Tense The past perfect tense denotes an action that has been completed at a certain time in the past or before a certain action took place. In short, the time denoted in the past perfect tense is "past past".
