Answer 1

Tom,do you really enjoy surfing the Internet?Yes.It'_________
A.such a great fun B.such great fun C.so great a fun D.so great fun
为什么选B?
so+形容词.+a/an+名词
such+a/an+形容词+名词
但fun是不可数的,所以不能加冠词,B正解
China today is no longer_______it used to be.
A.that B.which C .what D.where
为什么选C
表语从句中,what作宾语,表语,而that不作任何成分,只是连接词
而which相似that
而本题中 it used to be.明显缺表语,所以C正确
I can't stop playing computer games.For your health my boy.I'm afraid you _____
A.can B .may C.must D.have to
为什么选D
have to:除了必须外,还有个意思是“不得不” 通常是在某种原因下的一种 被迫 选择,表客观
这里是为了他的健康 这种特殊原因,所以才作出“ 不得不” 的这样一个选择,must并不是不可以（表主观）,这是选择题,最合适的 才能成为答案
