重点解释

Scientists already knew that if we overate fat cells blow up like balloons科学家已经知道，如果我们吃得太多脂肪细胞就会像气球一样膨胀

blow up:爆炸；充气；放大

Can you lend me a pump to blow up my bicycle tyres?

你能借给我个打气筒给车胎打打气吗?

词义辨析:

blow up, burst, explode这三个词(组)的共同意思是“炸毁”。其区别是：

blow up指人炸毁汽车、楼房等物体; explode指炸弹、锅炉、油箱等爆炸; 而burst指气球、轮胎等爆炸。例如:

The car blew up.轿车被炸毁了。

When the boiler exploded many people were injured.因锅炉爆炸,许多人受了伤。

The tyre burst.轮胎爆炸了。

It's changed the way we view fat tissue ever since.它改变了我们看待脂肪组织的方式

ever since:从那时起； 自那时以来

We've been friends ever since we met at school.

自从我们在学校认识之后，我们就一直是好朋友。

He has disappeared for ever since then.

从那以后，他就永远地失踪了。

A dumb cell was turning out to be a smart storage system.迟钝的细胞意外地成为了活跃的储存系统

turn out to be:结果是

The chief conductor turned out to be a young woman.

列车长原来是一位青年妇女。

I hope everything will turn out to be all right.

我希望一切顺利
