swing up saw的意思|示意

A child on a swing looked up at the scream and saw something like a small boy rolling and holding and falling fast through the branches of the pine tree.

一架荡秋千上，有一名孩子抬头朝尖叫声发出的地方看去，看到似乎有一名小男孩在松树的树枝当中翻滚、抓住树枝、迅速下落。

As soon as they saw that we had secured him, they would swing around the corner, pick us up and take off.

一看见动手就从拐弯那边冲过来，拉上我们就跑。

我看见他挥起右臂。
