动词
我们已经学过怎样用 am、are 或 is 和加了 ‑ing 的动词来说正在进行的动作。想说过去某段时间正在进行的动作时，就改用 was 或 were！
It was raining all day.
一整天都在下雨。
We were watching movies all night.
我们一整晚都在看电影。
He was talking too much during the movie.
他在看电影期间说了太多的话。
Is everybody here?
来看看 everybody 这个词吧！虽然这个词提到的是很多人，你却要说 Everybody was laughing ，不可以说 Everybody were laughing 。
Everybody was speaking French.
每个人昨天都在说法语。
Everybody was working on that project for six months.
每个人都为那个项目工作了六个月。
nobody 和 anybody 也一样。用于这两个词的动词，跟 he、she 和 it 的动词形式一样。
Nobody wants the room with the small closet.
没有人想要有小壁橱的房间。
Does anybody have a green pen?
有人有绿色的笔吗？
Don’t hurt yourself!
想用英语表达别弄伤你自己或她切伤了她自己，就说 Don’t hurt yourself 或 She cut herself 。
myself = 我自己
yourself = 你自己
himself = 他自己
herself = 她自己
I fell and hurt myself while we were camping.
当我们在野营时，我摔倒然后弄伤了我自己。
He hurt himself while he was playing rugby.
当他在打橄榄球时，他弄伤了他自己。
When VS While
while 和 when 的句子看起来虽然很像，但其实有区别！while 一般用在持续性的活动。
While we were camping, we saw a bear.
当我们在野营时，我们看到了熊。
While I was washing dishes, I broke a glass.
当我在清洗盘子时，我打破了一个玻璃杯。
when 却是用来形容活动被某事件打断的情况。
We were having a picnic when the storm began.
当暴风雨开始时，我们在野餐。
话虽如此，可不要被这些小区别吓到哦！when 和 while 其实可以放心交替使用。
She was skating when she fell.
当她摔倒时，她在溜冰。
While she was skating, she fell.
当她溜冰时，她摔倒了。
