问题描述:

为什么 选这个
1.It ____for 5 days and no one knows when it will stop.
A.has rained B.is raining C.has been raining D.was raining
为什么选【C】而不选【B】
2.I was told that he ___a speaking note yesterday but I don't know whether he has finished it.
A.was writing B.wrote C.had written D.has written
3.The college graduate insisted that he_____to Tibet for the Western Development.
A.be sent B.was sent C.would be sent D.will be sent
4.The vegetables are cheap;however,the chef has prepared a nice meal with them.

1 、C是现在完成进行时,表示事情在过去发生并且一直持续到现在,题意是:雨是5天前下的,一直下了5天,现在依然在下,没有人知道什么时候停,所以只有现在完成进行时才能完整表达这个意思
2、A,题意是:我昨天被告知她正在(是过去正在写)写一个发言稿,但是我不知道她是否完成了,所以应该用过去进行时,表示过去正在发生的事
3、A,insist后面接that从句时要用虚拟语气should be sent,should可以省略,直接用be sent
4、译:(虽然)这些蔬菜都很便宜,然而,厨师已经和他们准备好了一顿美餐

时态的问题。2 C, 3 C
4这些蔬菜是很便宜的,但是主厨却用这些便宜的蔬菜做出了美味的大餐。

1.C for 5 days 典型的现在完成时时间短语,表示从过去持续到现在的动作。
2.B 从句时态受主句限制
3.A 虚拟语气
4.尽管这些蔬菜很便宜,厨师却用它们做了不错的一餐

1 for 5days 后面可以用完成时 也可以用完成进行时 no one knows when it will stop说明雨一直在下 强调动作的进行
2 A
3 A 虚拟语气
4蔬菜很便宜 然而厨师长已经用他们准备了好吃的
希望能帮到您

1 .has been raining 是现在完成进行时,表示这个动作从过去开始一直干到现在且还可能持续下去.据语境这里的雨尚未停,所以选这个更合适.2 A 过去进行时,因为不晓得是否他写完,只能说看到他昨天正写.过去进行时只表过...
