常见错误
四个仍在继续的失误
当 -ing 被省略、has 追逐了错误的主体，或该时态试图驶入一个已完成的过去时刻时，引擎就会熄火。
I have been work all day.
I have been working all day.
💡 -ing 是这个时态的引擎。
She have been sleeping for two hours.
She has been sleeping for two hours.
💡 has 与 she 搭配。
I am working here since 2020.
I have been working here since 2020.
💡 Since + 起始点需要现在完成进行时来表示持续的动作。
I have been going to London yesterday.
I went to London yesterday.
💡 过去的一个已完成时刻使用一般过去时。

一道题选出双胞胎

Since 和 For，再一次
从 since 开始，用 for 延伸
这个时态与 since 和 for 共存。这是该对词组的一瞥提醒。
Since + 一个时间点
起跑线since Monday · since 9 a.m.
For + 一段时间
延伸段for two weeks · for ages
⚠️ 时间点→since。延伸段→for。
