1._C_with a diffcult situation,arnold decided to ask his boss for advice.
A.TO face B.Having faced C.Faced D.Facing
第一题是因为后面说的是人,而前面没有主语,所以要用ed形式.
2.Whom would you rather __have do__the work?
为什么用have do
第二题是因为有个短语是have sb do sth 让某人做某事
3. there is nothing more i can try __to persuade__you to stay so i wish you good luck.
为什么用 to do
第三题这样看,把句子分成两部分来看,第一部分,there is nothing i can try,句子到这实际上已经说完了,但是它有强调了一下,try的目的是persuade you to stay,所以,这里的to是表目的的.
4.At the beginning of class, the noise of desk __C__could be heard outside the calssroom
A.opened of and closed B.to be opened and closed C.being opened and closed
D.to open and close
这个句子从意思上理解应该是一个被动,怎么说呢,the noise of desk,是指桌子发出的声音,而桌子是被打开又关上所以才发出声音的,所以先排除A、D,在B、C里面看,主语是物的话,应该用being.
5.there are two thousand students in our school, __D_are girls
A.two-thirds in which B.two-thirds in them C.two-thirds of them D.of whom two thirds
这个句子用排除法就可以做,1,这明显是一个从句,排除B、C,再看A、D这个句子前后是一个所属的关系,所以从介词上看应该用of,再说,后面这个句子缺的是主语,which是指物的关系代词,故应该用whom而不是which
6.there are invented me to their party, _A_ is kind of them.
A.as B.where C.when D./
这个句子应该是they invited me to the party吧,这里的as是因为的意思.如We all like her as she is kind. 我们都喜欢她,因为她善良.
7.Do you still renmember__A__a swim in the river when you were very young?
A.taking B.being taken C.to take D. to be taken
第七题这样看,remember doing 表示记得做过某事,而remember to do 表示记得要做某事,表示还没有做.当你小的时候,是已经做过的事,所以用doing.而这个句子是主动的句子,B表示被动,所以选A.noise of desk
讲解完毕,不懂得可以再问.
