在作动词，表示“关，闭合”的意思时，close与shut几乎没有区别，可同义替换。
- Shut/close your eyes.
- Can you close/shut the door?
- They close/shut the shops at 8 o'clock.
以下情况，最好用close而不用shut，如：We close (NOT shut) roads, bank accounts, meetings etc.
- You should close your existing account before opening a new account. (NOT You should shut your existing account ...)
需注意的是，口语中shut往往没有close正式，根据不同语境可能有不礼貌、强制性的感觉，例：
- Shut your mouth. 感觉像是一种很强硬的命令。
- Close your mouth. 感觉是一种请求，请求他人吃饭更优雅一些。
