1. Simple present tense
English, entry-level tense, verbs use the simple present tense, and are often used to describe habitual actions or states. Adverbs of time and frequency generally include: every day, every morning/afternoon/evening, always, often, usually, sometimes, etc. This is the simplest descriptive sentence pattern!
It should be noted that when the subject in the third person is singular, the predicate verb will change accordingly, usually adding S and ed, changing Y to I and es, adding S and double suffix, and special changes, if any-yes.
2. Simple past tense
When we learn the general past, we are not used to it, and the teacher begins to emphasize it. When we fill in verbs, we must look at the time. If it is the past tense, you should use the past tense. As long as this habit is reversed, it is generally easy to deal with in the past tense.
The most common past times are: yesterday, last week/month/year, just now, this morning, ………………………………………………………………………………………………. It is worth noting that in the past, when verbs changed, they were usually followed by ed, especially when they were written in pairs.
3. General future tense
Since the appearance of the past time point makes the verb become the past tense, then the appearance of the future time, we naturally use the general future tense. Fortunately, we don't need to tamper with the verb itself, just use the prototype of be going to+ verb or will- verb, be+to do to indicate future usage and so on.
4. Simple past and future tenses
This understanding should combine the general past tense with the general future tense. For example, the time range is set in the past, but it is about what to do. At this time, the simple past and future tense is used, which is generally used for indirect speech. Who in their right mind would say such a thing directly? In addition, it can also be used to describe the future from the macro perspective of the past.
5. Present continuous tense
Describe what you are doing, which is relatively easy to understand. Translation into Chinese will definitely have the word "positive".
