blowing-off

We got our roof blown off in the gale last night.

昨夜的大风把们的房顶给掀掉了。

A gust of wind blew my hat off.

一阵大风吹走了的帽子。

In the lightning I saw that the roof of the hut had been blown off.

闪电的时, 见棚屋的屋顶被掀掉了。

You’ll have to stay here until the blizzard blows itself off.

你得等风雪停了再走。

The surplus steam was blown off through the pipes.

多余的蒸气通过掉了。

The speaker has to ad- lib his speech when his papers suddenly blow off the podium.

当演讲稿突然掉下台时，演讲者不得不现编词。
