动词
用英语来谈论过去的经验一点也不难，来看看下面的例子吧！
Have you ever had an omelet?
你有吃过蛋饼吗？
No, I have never had an omelet.
不对，我从来没有吃过蛋饼。
你也可以用 have 或 has 来谈论最近发生的事、重复的动作或者做某事做了多长时间了。注意哦，have 和 has 都有缩读形式，像 he has 能缩成 he’s。
He's just taken some beautiful photos.
他刚拍了一些好看的照片。
How many times have you seen this movie?
你看到了这部电影几次？
They've worked together since 2005.
他们自二〇〇五年以来就一起工作。
别忘了！一般在 have 或 has 后面的动词，都可以直接加上 ‑ed (像 has worked )。但是，某些动词却有不规则的拼法。来看看一些我们学过的例子吧！
be, was/were → been
see, saw → seen
take, took → taken
see, saw → seen
take, took → taken
How many times?
谈论做某事做了几次时，除了用 one time 和 two times，你也可以参考以下的表达方式！

不对，他们只一起跳了一次舞。

如果想谈论做某事做了多长时间，可以在时间前面用 for ，或在时间的开头用 since 。
