Punctuation-Question marks, Exclamation marks and Quotation marks
THE QUESTION MARK (?) 問號
The question mark has one use, and only one use. It goes at the end of a sentence which forms a question, and is used in place of a full stop. For example: How old are you?
One thing to be very careful about is to not include a question mark when it is not required. This is a very common mistake, especially when expressing a thought that appears to beg an answer.For example : “I wonder what the time is.” This is a statement not a question, so no question mark.
THE EXCLAMATION MARK (!) 驚嘆號
An exclamation mark is only used when issuing a command, speaking forcefully or after an interjection (e.g. Wow!). It replaces the full stop at the end of the sentence. Do not use more than one exclamation mark per sentence. Multiple exclamation marks are completely unnecessary and annoy many people; especially English teachers!
QUOTATION MARKS ( “ ” ) 引號
Quotation marks are used to quote another person’s words exactly, whether they are spoken or written. For example: John said, “I am going to see a movie with my girlfriend tonight.” Note the use of the comma after John said.
If you are quoting a person who is quoting another person, use single quotation marks. For example: John said, “I have just broken up with my girlfriend. She said ‘I never what to see you again!’ and then walked out on me.”Punctuation that belongs to the original quote should be inside the quotation marks.Punctuation relating to the entire sentence should be outside. For example: The teacher asked,“Have you done your homework?” Do teachers always say to their students, “Do your homework!”?
Quotation marks can also be used to denote irony or sarcasm, or to note something unusual. For example: My new “unbreakable” camera case broke last night.
