The second application of the present continuous tense

In practice, the present continuous tense is often used in the following situations:

(1) When there is now in the sentence, it often means that the action is going on, so use the present continuous tense. For example:

They are playing basketball now. Now they are playing basketball.

(2) The sentences beginning with look and listen remind us that the action is in progress, so we should use the present continuous tense. For example:

Listen! She is singing an English song. Listen, she is singing an English song.

(3) It means that the action is going on for a period of time or at the present stage, and there are adverbials of time such as this week and these days, which are often used in the present continuous tense. For example:

We are making model planes these days. We are making model planes these days.

(4) Describing the actions of the characters in the picture is also to express them more vividly. The present continuous tense is often used at this time. For example:

Look at the picture. Children are flying kites in the park. Look at this picture. Those children are flying kites in the park.

A. It's lost, don't look for B. It's gone, don't look for C. It's lost, but it hasn't been found. D. It's gone, but it hasn't been found.

E: The present continuous tense can sometimes be used to express admiration or boredom. For example:

Swim, start, play, double the last letter, and then add ing
