The sentence quoted in quotation marks is the original sentence. In English, you can use neither double quotation marks nor quotation marks in the title.

The usage of single quotation marks and double quotation marks is the same in Chinese and English. The only difference is that before using quotation marks, Chinese is colon and double quotation marks. English is commas, spaces and double quotes.

Quoted comments

When using quotations, pay attention to the position of punctuation marks at the end of quotations. Always use the quoted words independently, and put the last dot in quotation marks. If the quoted content is a part of a sentence, that is, the quotation has no independence, and there is no need to use a dot at the end of the quoted part (question mark and exclamation mark can be reserved), and the whole sentence stops at this pause, what dot should be used?
