1. It `s five years since I _________(study)English.
2.He always has ______(那么）little trouble.
3.I don`t know _______(是,否）to go .
4.There is no water _____(and / or) no air on the room.

答案

1.studied 2.so 3.whether 4.or 请相信我的答案.第一题是强调句,since后必须用过去式.第二题原因是little,many much 必须和so连用,第三题是因为to go ,if虽然也有是否的意思,但不能与todo 连用.最后一题则是因为两句都是否定,否定用or 肯定用and
