Unit 13 We’re trying to save the earth!要点详解

1. We’re trying to save the earth!

我们正尽力拯救地球！

(1) 本句时态为现在进行时，表示现阶段正在做的事情。现在进行时所表示的动作并不一定在说话人的说话时刻进行，而是在包括说话时刻在内的一段时间当中进行。例如：

(2) try to do 表示“设法或尽力去做某事”，实际上做与不做，视情况而定，而try doing表示“试着做”，即动作真的进行了或正在进行，成败则视结果而定。例如：

He tried to read, but he was too tired to read much.

他想设法看书，但太疲倦了，没看多少。

He tried reading, but that could not make him forget his trouble.

他试着看书，但这并没使他忘记烦恼。

(2) like做介词时可用very，very much，rather，quite等副词修饰。例如：
