{01} China"s reform and opening has been going on for ________ is like about 30 years now and it"s really quite remarkable.
A.that
B.which
C.what
D.it
解析:答案:C 考查名词性从句。句意:中国的改革开放现在已经进行了大约三十年,效果非常明显。________ is like about 30 years now是介词for的宾语,该部分缺少主语,所以选起双重作用的what。 本题选C。 {02}Have you noticed the problem ________ he is now in low spirits?________ come?
