A. The reporter interviewed some families, and many parents reported that their children have a lot of homework and a long homework time, and sometimes they do homework until late at night. These situations exist in many schools across the country. (Wrong, the colon only goes to "homework late into the night", and the comma after "late into the night" should be put to a full stop. )
This amazing fact proves that if you always think about money and can't see the enemy's corrosive attack, people will go astray. It can be seen that these facts can be used as living textbooks. (wrong, the colon in the sentence only means "going astray", not including the back, so it is wrong. The comma after "go astray" should be changed to a full stop. )
C Mao Zedong has two poems: "Only heroes drive tigers and leopards, no heroes are afraid of bears", from which I feel the fearless spirit of * * * producers. On the surface, the content after the colon is the full scope of the prompt. Actually, it is not. There are only two poems here. Either change the colon to a comma or change the comma to a period in quotation marks. )
2. You can't use colons when reporting. (It is said that it has been changed)
The teacher said that he was not feeling well today and would not come to give lessons to his classmates. (right)
We should keep in mind Chairman Mao's teaching: "Study hard and make progress every day" and strive to be three good students. (Wrong, remove the colon)
3. If the following article is not a quotation and the name of the person has not changed, then the preceding article can be a colon or a comma.

4. There is no big pause without a colon (there must be a pause with a colon)
Excellent films such as Storm, Song of Youth and Lin Zexu will also be shown in major cities. (Wrong, remove the colon)
5. "So-and-so" and "So-and-so" are quoted directly without colons; The speaker cannot use a colon in the middle of his speech; Put it after what you said and add a period. For example:
He said he wouldn't go home today.
"This problem," said Li Ming, "let me think about it."
"If you fall behind, you will be beaten." Deng Xiaoping warned us.
6. Colons can also be summarized. But if a period has been used between several summarized sentences, you can't use a colon to summarize the above, because it is easy to be misunderstood as a summary within the last period. When you use a colon to guide the following, you should also pay attention. If the led content exceeds the following period, it is best to use a period instead.
He doesn't like studying, he likes sports, and everyone loves him. That's all I know.
7. You can't use two colons in the same sentence.
"At the meeting in the evening, Secretary Zhang announced that the factory should implement two reform measures: one is to work with certificates, and the other is off-the-job training."
Commentary: "Announcement" is followed by a colon, and "Measures" is followed by a colon, which is not in line with the habit of punctuation. Generally, only one colon can be used in the same sentence, otherwise it will be difficult to identify. One of the two colons should be changed to a comma.
