是否需要英文

做家庭作业是否需要检查可以这样翻译：Does the homework need to be checked after being done?看电影是否需要啊票。Do we need a ticket to see a movie?是否其实就是一般疑问句的引导词，可以使do/does/will/am..., 看具体情况具体翻译吧, 和汉语不一样。希望能帮到你！

都不是。don't need

whether

do homework 意思： 做作业，是一个固定搭配。不需要 checkDid you do your homework yesterday?

please both of you to confirm whether you need RES. if yes,Wendy will start next process with our vendor at once.

老外用的是No need. 不需要，不是 no needed.这里的need 是名词

whether or notwhether she will come or not is a question.她是否来还是个问题

可以用 if，也可以用whether

whether or not例如:It ceased to matter whether or not he sold his work. 他是否卖掉了他的作品已无关紧要。if例如：I wonder if she is ill.不知她是否病了。whether例如：His nationality isn't relevant to whether he's a good teacher. 他的国籍与他是否是位好老师无关。I'm uncertain whether to go or not.我不能肯定去还是不去。
