95.To learn to speak perfect English,----.
A.plenty of practice is needed
B.you need plenty of practice
C.what is needed is plenty of practice
D.you need doing plenty of practice
答
凭感觉应该是A.
答
选B,to learn to speak perfect English的主语是人，所以删除AC,而need后加do或to do。所以选B。如果要选A,C,需要把状语改成For students /you to learn to speak perfect English。不知道有没有解释清楚，呵呵
答
选B吧.
To learn to speak perfect English不定式作状语,后面主语应该要是人而且句子完整……
希望是对的嗯.
答
选A，像这种To句型表目的的，后面一般跟被动语态，也可根据语感，语感的话平时多读多练可以培养的哈！
