When I throw up a hammer, then the hammer will do very weird things.

当我抛起一把铁锤时，它也会奇怪地运动。

If I throw up a hammer, then the center of mass and only the center of mass will just go along a perfect parabola as if it were just a tennis ball.

我若是抛铁锤，那么质量重心，也是唯一的质量重心，会沿完美抛物线运动，就像一颗网球。

I like you because if I think I am going to throw up then you are really sorry, you don't just pretend you are busy looking at the birdies and all that.

我喜欢你，因为，如果我觉得不舒服，你会真的替我担心，而不会假装自己正在忙着看小鸟什么的。
