补充相关例句：

▲will表推测的用法

Ask him. He will know. 问问他吧，他大概知道。（出自《薄冰高级英语语法》第277页）

That will be your book. 那是你的书吧。（出自《外研社-建宏英汉多功能词典》）

▲would表推测的用法

Few people would agree with this. 很少人会同意这种看法。

That would be in 1976, I think. 这一定是1976年的事，我想。

以上两句均出自《张道真英语语法》第172页。

黎老师：

would (或will)与动词原形连用，可以表示对现在情况的推测。如果表示对过去情况的推测，可以用“would (或will) have + 过去分词”结构。例如：
You would never guess. = You will never guess. 你可能/大概/也许永远也猜不出来。
He would have reached New York. 想必他已经到达纽约了。
