Would you mind？和Do you mind？ 用于询问或请求别人做某事，或请求他人的许可。（1）mind后面可以用-ing形式 Would you mind doing the dishes? = Do you mind doing the dishes? 请把餐具洗了好吗？（表示请求别人做事） Would you mind turning down the radio? = Do you mind turning down the radio? 请把收音机关小点好吗？（2）Would you mind my doing？ = Do you mind if I do？ 这个句型用于询问他人意见或请求他人的许可。 例如：Would you mind my smoking here? 你介意我在这里吸烟吗？ Would you mind my asking you a question? 我问你一个问题好吗？ Would you mind my opening the window? =Do you mind my opening the window? 我可以开窗吗？（3）询问人们感觉的一般性问题，可以用Do you mind？ Do you mind people smoking in your house? 你介意别人在你家里吸烟吗？（4）这个句型的否定形式是在mind后加not Would you mind not playing basketball here? 你不要在这打篮球好吗？ Would you mind not wearing those old jeans?（5）回答Do/Would you mind？ 提出的问题时，表示允许要说No或Not at all等； 如果介意要做肯定回答Yes. 或Yes,Im sorry,but I do.等， -Do you mind if I ask you a question? 我可以问你的一个问题吗？ -No,please do.可以，请问吧。2. 通常既可用whether 也可用if 表示“是否”来引导从句，常置于see,ask,learn,tell,wonder,doubt,find out等动词之后。 例如： Im not sure whether /if Ill have time. 我不敢肯定我是否会有时间。 He asked me whether/if I could help him. I want to know whether/if he lives there. 只能使用whether的场合（1）只有whether能用在介词后面 Success depends on whether we make enough effort.（2）与or （not） 连用的词通常是whether Whether we help him or not,he will fail. 不论我们帮助他与否， 他都将失败。（3）带to的动词不定式前用whether,而不用if Please tell us whether to go or stay here.请告诉我们是走还是留。 They didnt know whether to agree or keep silent. 他们不知道是应该同意还是保持沉默。（4）whether可置于句首引导主语从句，而if不能 Whether the meeting will be in Beijing is not known yet. 会议是否在北京举行还不得而知。3. get on / get off 上/下（公共汽车、火车、船、飞机） She got on / off the bus quickly. get的其它的用法：（1）表示“到达，抵达”,如果后接表示到达某地的名词，get后面要接介词to,如果get后接的是地点副词就可以直接在get后使用。 She got there at six. 她六点钟到达那里。（there为地点副词） When we got to the station, the bus was waiting.
