I. Period

1 and a period are used at the end of a sentence.

2. The period can also be used as the abbreviation of English words, such as mrs, dr, etc. But be careful not to use a period when abbreviations form a word. Such as ibm, dna and so on.

Second,? question mark

Question marks should be used in direct questions, not indirect questions. For example, how would you solve the problem? Is the correct usage, but is it used in I wonder how you will solve this problem? That is wrong. You should use a period instead of a question mark. Besides, in polite expressions, a period is also used instead of a question mark, for example, can you call me tomorrow?

Third,! exclamation mark

Exclamation marks are used in exclamations and interjections. Pay attention to the application of exclamation marks in business writing, because exclamation marks are inappropriate.

Use will appear abrupt and unstable.
