C答案是肯定的了,下面我给你解释一下为什么.
要说一下use 这个词的用法.
1:sb used to do sth:某人过去常常做某事,表明现在不这样做了,给你举个例子:
I used to go to school by bus,but I've got a car now.我过去坐公交车上学,但是现在我有车了.
2:be used to:这里要注意,这个后面可以接doing,也可以用do,如果接doing,那这个句子就翻译成“习惯了做某事”例句:I am used to staying up late at night.“我习惯熬夜了”.注意,在这个句子里,to是介词,因此后面要用doing.
如果接do,那就翻译为“被用来做某事的”例句:“this medication is used to get you better"翻译为“这种药是用来让你康复的”,在这里,to不是介词,而是不定式符号,所以后面接动词原形do.
3:be used for:翻译为“被用来做...”后面可以接名词,代词,动名词doing
例句如上句:this medication is used for your recovery“ 这种药是为你康复而用的.
this medication is used for you:这药是用在你身上的.
this medication is used for geting you better,这个句子=this medication is used to get you better,因为for是介词,所以后面接doing.
4:be used by:被...使用的.this medication is used by doctors:医生们都使用这类药物.
be used as:被作为.而使用.sugar can’t be used as salt:糖不能当作盐来用.
希望有助于你.
