一道高一英语题 求解

34. If your call is not answered within two minutes, you______ to hang up and dial again.
A. would be advised B. are advised C. have been advised D. were advised
the answer is B. why noT A?

Answer 1

不是虚拟语气，考的是真实条件句。条件句可分为两类，一类为真实条件句，一类为非真实条件句，非真实条件句才会采用虚拟语气。如果选择A的话，表示事实将来发生来的可能性很小。而且并不涉及与现在或者过去相反。所以选择B

表示对将来情况的主观推测。如下例子：
1．If he should come here tomorrow,I would talk to him.
如果他明天来这儿的话，我就跟他谈谈。（事实：来的可能性很小）
2．If there were a heavy snow next Sunday,we would not go skating.
如果下周日下大雪，我们就不能去滑冰了。（事实：下雪可能性很小）
3．If she were to be here next Monday,I would tell her about the matter.
如果她下周一来这儿的话，我就会告诉她这件事的始末。（事实：来的可能性很小）

你这里发生的可能性并无法判断

追问

如果是will be held可以吗

Answer 2

A 理解为will be 的过去时。这句子是现在时的啊。。。。。

Answer 3

这是真实情况而不是虚拟

Answer 4

A是被动语态，在这里使用不合适

Answer 5

看前面的if引导的从句，用的是一般现在时态，所以可以肯定的是，这里不是用的虚拟语气。

不是主将从现吗
