还有就是第6题,正确答案应该是A.

1.She was so surprised that her mother____(等待)for her.2.Chinses culture is not so easy _____(understand)3.sometimes it isn't easy____a good teacher at school.4.there are three girls waiting____(cross)a busy street.5.Usually it is difficult___(be)
1.She was so surprised that her mother _was waiting_(等待)for her.
-wait for sb 等某人,that后从句要和主句时态符合,所以用过去（进行）时
2.Chinese culture is not so easy _to understand_(understand)
-so + 形容词 + to + 动词
-这句话：中国文化不是那么容易理解的.
3.sometimes it isn't easy _to be_ a good teacher at school.
-be + 形容词 + to do sth,做某事是怎样的.
4.there are three girls waiting_to cross_(cross)a busy street.
-wait to do sth ,cross 是动词,穿过
5.Usually it is difficult_to be_(be) a good leader there.
-同3
6.Can you tell me_B_with the mobile phone.
A.what's the matter
B.what the matter is
C.before he will come back
D.until he comes back
因为空格处的内容是tell的宾语,所以从句要用陈述句的语序
-------------------------------------------------
我坚持我的观点.
他给的答案仅仅是参考..而不能说是"正确"答案..(我们老师说的)
要敢于质疑啊
如果题1用waiting,这个句子就不对了.因为空格处缺的是谓语,waiting怎么能做谓语呢?如果是进行时,要有助动词be啊.
第3和5题,都是 it is adj.to do sth 这样的一个句式,
我可以肯定,你也可以从书上找到类似的句式.
但是从没见过 it is adj.doing sth
还有第6题,空格处如果是tell的宾语,宾语如果是句子,那这个句子就要用陈述的语序.A是疑问的语序,倒装过了;B是陈述的,所以选.
然而一开始我也忘记考虑了...如果空格处是状语...C和D都是状语,C错在will,应该改成before he comes back;D也是错的,因为tell是瞬间的动词,一瞬间的事情是不能延续到he comes back的.(或说until带的时间状语是一段时间的,而不是瞬间的)

1.was waiting/had been waiting
2.to understand
3.to be
4.to cross
5.to be
6.B
主要是动词不定式的训练

3和5的it是形式主语呀，动词不定式to be才是真正的主语．
