请问这道英语题怎么做
1.a phone call sent her ____to the hospital. A to hurry B hurry C hurrying D hurried 2.They must have been enjoying themselves there ,otherwise they___so long. A can't have stayed B wouldn't have stayed C couldn't stay D needn't have stayed 应该选哪个呢,为什么呢,谢谢
第一题 send sb to do sth 派遣某人去做某事 send sb doing sth （迫）使某人做某事 所以第一题选 rrying 电话不会派遣他去做事情，只能是驱使他匆忙的去了医院。 第二题是一个含蓄条件的虚拟语气的主句。前半部分是推测用法：他们在那儿一定很快乐；后半部分的意思是：否则他们不会呆那么久。事实是他们在那儿呆了很久，所以才有前面的推测。 答案为B.wouldn't have stayed.此题的关键词是otherwise，类似的还有：or(否则，不然的话）， without(要不是有了。。。）,but for(除非，要不是有了）等。
分别是A、B。
第一题是A ，第二题是B
选B
。a phone call sent her ____to the hospital。 A to hurry B hurry C hurrying D hurried 2。They must have been enjoying themselves there ,otherwise they___so long。
A can't have stayed B wouldn't have stayed C couldn't stay D needn't have stayed 1,选a, dosth。派,送,差遣某人做某事,Shesenthersontobuysomebutter。
seng sb。+形容词/分词，使。。。。。。成为/陷入（某种状态）The news sent her mad 。The blow sent him staggering for a moment。那一击使他一时站不稳。 2。
otherwise=If they hadn't enjoyed themselves there,所以选a,于过去事实相反，can't have stayed比wouldn't have stayed 语气强，前者“不可能”，后者“可能不会”。
1 B 2 A
2b 我的语感，hoho
