英语题一道

⑴_____ ，we shall go on a picnic tomorrow.
a)if the weather were fine b)were the weather to be fine
c)should the weather be fine d)if the weather will be fine
为什么选c，不选b

Answer 1

同学，你好。C项是IF从句的倒装形式，常见的共有三种：
1.Should sth./sb/ do sth.=If sb./sth. should do sth.（现在或将来时）
2.Were sth. /sb. to do sth.=If sb./sth. were to do sth.(过去的事情）
3.Had sb. /sth. done sth.=If sb./sth. had done sth.(表过去，表完成）
根据句意，显然B项不符，应选C.

追问

were to 不应该是表示对将来虚拟的嘛？

追答

Were to 表对将来虚拟是指与事实相反或几乎不可能发生的事情的虚拟。
eg.Were I you ,I would pick her up.

Answer 2

If引导的是个条件状语从句（主句用一般现在时从句用一般将来时） 不懂望追问

追问

were to 不是表示虚拟将来的嘛？

Answer 3

If引导的是条件状语从句,主句一般用现在时或一般将来时

追问

were to 不是表示虚拟将来的嘛？

追答

Were sb to do sth.=If sb were to do sth这个是表示过去的事情哪。
