几个高中英语语法题目,有耐心的高手来.
几个时态的题目.
1
----I didn't expect that the project would be so complex and time -consuming .
-----Neither did I , By next Monday, it _____longer than all the previous combined
A will have lasted B will last

2
-----Mr.Wang is now in hospital .
------Sorry to hear that . Think it's years of hard work and little rest that ____his health .
A ruined B have ruined

3
Finally the parcel arrived by post , in which_____wrapped dozens of old coins .
A has been B were C have been C was
1.A 【“by + 将来的一个时间点”作状语,句子用将来完成时.】
2.B 【句子当中有强调结构 it is/was ...that.其中,it's = it is,所以that 后面的谓语动词需要现在时态,而A是一般过去时.】
3.B 【倒装结构.主语是dozens of old coins,可数名词复数,而主句的时态是一般过去时arrived,所以从句也要一般过去时.】
再问: 第二题,你怎么知道是 it is 强调句型的is/was 影响从句的时态?
再答: 因为完整的句子是:Years of hard work and little rest have ruined his health. 此时,可以看出它不缺任何成份。 不是is/was影响时态,反过来才对,即have ruined决定了需要is而不是was。
