Under what circumstances should a verb be ING? Make a list of all the situations!

It's too cumbersome on it.

To put it simply, if you want to express what you're doing at the moment, like I'm typing at the moment, then add ing to the verb of typing....Think of it as English and that's how it is added.

Also, if you want to use a verb as an adjective, as mentioned above, you should also add ing....To borrow the example above: I bought some reading materials.

Geund) In this sentence, read was originally a verb, and now the predicate verb used to express the action in this sentence is not read, but buy, that is, buy, but here read is added to ing, and it becomes an adjective, which means to read.

There are simpler ones.

Main dynamics. After the verb be, add ing

When a verb is the subject, ing is added. It becomes a gerund.

Add ing after a preposition (except for verb infinitives).

Then there is the addition of ing to modify the noun when making adjectives. (Of course, changing the past participle can also modify the noun.) It's high school English, right?).

I guess it's gone. But the first floor feels better.

There is a phrase that is be doing sthIt can be used in both the present and past continuous tenses.

i.e., using the ing form in the present continuous tense and the past continuous tense.

I suggest you take a look at the grammar of thin ice, which is very detailed.

Present continuous tense be doing

Add after the preposition.

After some specific verbs, like enjoy.

As the subject, add ingThen there must be a predicate verb after the sentence. For example, playing sports is good for your

health.There is a predicate is, then playing as the subject, plus ing

Present continuous tense. After the preposition. There are also fixed collocations and the like.

Now there is also after the verb be in the continuous tense.

The beginning of the sentence is in the original form of the verb, and being the subject is the ing form of the verb.

The original form of the verb begins with an imperative sentence.
