题目

麻烦各位了.
1.get down to sth ,look forward to ,object to ,pay attention to 等等后接sth、v-ing 时,to 为介词,那可不可以跟to do当状语?why?
2.When asked how they were paying for their education,almost a third of the students said …… 此处为何用asked 而不用being asked?
3.They stayed with me three weeks.me后为什么不加介词?
4.Try hard as he will,he…… "Try hard"是表语还是状语,为什么可提前?As he likes her much,he does get angry with her sometimes.这个句子为什么错?为什么一定要用Much though he likes her,he……?as/though不是可倒可不倒吗?
5.Alone in a deserted house,he was so busy with his research work that he felt anything but lonely.逗号前的是独立主格结构吗?省略那些东西?
6.There be no sth.sth是单还是复还是均可?意思一样么?

答案

to不是在每个时候都是介词的,有时侯也是不定式(to引导的句子)
第一个:get down to sth.是开始认真对待(考虑)所以不行.
第三个:object to后只能接名词或动名词,所以不可以.
第二个:look forward to后面只能接名词和动名词,所以不可以.
第四个:pay attention to 后只能接名词或v-ing,所以也不可以.
省略了主语.那如果加上主语,别看when就是一个间接引语拉!
with是介词.所以就不用介词拉.
其实try hard可以放在后面,只是强调.
因为你多了个does啊!
强调嘛!
省略主语.
均可.一样比如:there is no reason to do sth there is no enough time to do sth
