一、关于what would you do if 用法的疑问
有一年高考的单项选择考过这样一道题:
(1)what would you do if your father didn't approve your plan?
(2)what would you do if you had to leave now?
(3)waht would you do if they didn't trust you ?
最佳答案
what would you do if..是假设的意思...如果是说将来的事情,像题中的..就要用一般现在时.
而如果是说现在或以前发生过的事的话,就要用过去时了..和if的用法很相象
二、有一道题是这样的:
What if you_______yourself in the laboratory?
A.would clone C.cloned
我觉得是A,可答案是C。谁能告诉我为什么。。。顺便详细介绍一下what if的用法
我在课本上看到一句话:What if you could combine a cow and a tiger?
如果刚才的问题真的是选C的话,那这句和那句有啥区别呢
问题补充:
what if是不是就等于 What would happen if 呢
最佳答案
what if ... ?
如果... , 会怎样?
if 是用来假设一个状况:
状况子句要用过去式(did), 后果子句用过去未来式(would do).
举例
问: What if you cloned yourself in the laboratory?
答: Then I would play chess games with my clone.
could 是can的过去式, 所以用在状况子句.
would 是用在后果子句.
举例
问: What if you could combine a cow and a tiger?
答: Then there would be a new animal specie.
What if 是等于 what would happen if :)
.what if从理论上讲后面可以跟一般现在时,也可以跟一般过去式的虚拟语气,但从数量上看虚拟语气很少用,但依然可以根据语境选择跟虚拟语气。
三、what if:如果...将会怎么样
例句与用法:
1. What if it is true? 如果这是真的又该如何呢?
2. What if he doesn't agree? 如果他不同意该怎么办呢?
3. What if he comes back now? 如果他现在回来怎么办?
4. What if I fail! 即使我失败了又怎样
PS:what if 和 if 的区别:
简单点说就是,what if的意思是“如果...将会怎么样”.有
“要是”的含义,比if带点肯定的怀疑在里面。
What if it is true? 要是这是真的这么办呢?
What if he doesn't agree?
而if仅仅就是“如果/假设”的意思。
If it is true? 如果是真的呢?
If he doesn't agree?
