每天三分钟学英语 第379期:英语中“不存在”的4种语法,你都会吗?

 今天要学的4种英语时态，
并不是真的不存在，
而是情态动词would的4种用法：

① would do
② would be doing
③ would have done
④ would have been doing

并不是英语概念里真正的时态哟~

would的用法很多，相对有难度。
难度不是来自于用法难，
而是跟与中文概念不同，
容易造成理解困难和偏差。

举例：以 would do 为例

1、礼貌用语
- Would you like some food?
你想吃点东西吗？

- I would like to book a table.
我想订一个位子。

- I wouldn't agree with that.
我不同意。

2、虚拟语气
It would be nice if I had a heater¹ at home.
如果家里有暖气就好了。

3、过去的习惯
He would call me at midnight. So annoying.
他以前会半夜给我打电话。好烦。

以上并非would的所有用法，
would的用法还有更多。

情态动词也有很多，比如：
will, would, shall, should,
can, could, ought to, must,
need, have to, may, might 等。

这是一个很大的体系，
值得像学时态一样好好学习。

1 heater   

n.加热器，火炉，加热之人

参考例句：

• If you are hot you can turn the heater down.如果你觉得热，你可以把暖气拧小。
• The heater is on a timer switch.加热器连在一个定时开关上。
