【知识点拨】

▲We should help save the sharks.我们应该帮助拯救鲨鱼。

save作动词，意为“救；拯救”，后常跟介词from。如：

He saved the boy from the big fire.

▲Have you ever taken part in an environmental project？你曾经参加过环境项目吗？

take part in意为参加，其后接名词或动名词。如：

Did you take part in any activity?

辨析join，join in与take part in

join 指参加某党派、团体或军队等，并

且成为其中一员。

He joined the army last year.

join in 指参加某项活动，多指正在进行的

活动。

I hope you can join in the discussion.

take part in 指参加某项活动(比赛)并在活动中起

一定的作用。
