(选哪个?为什么?）
4.This was the least interesting book ____ during my holidays .
A.I ever read B.I have ever read (选哪个?为什么?）

1.B.(这题我没有很确定,就是凭的预感,还有就是 is away有on business的意思)
2.A.(因为是第三人称的现在时态,所以可以排除B,D,句子中没有体现“她以前没有打过羽毛球”所造成的影响,而且还有"this time",所有倾向于用现在进行时)
3.A(句子中出现ago,所以一定是过去时,排除d,也不能用过去进行时.至于A和B,我觉得凭语感就是A,你可以念念看哪个比较顺口.答案一定是A)
4.B.（ever正常情况下是和完成时一起用的,在书面语当中一般不会出现“sb ever did sth 这样的句子.）
