5、strive vi.奋斗；努力；力求；斗争

英语释义：to try very hard to do something or to make something happen, especially for a long time or against difficulties

再看一下常见搭配：

strive for奋斗

strive with同...作斗争...

strive against反抗

strive to争取，追求

strive against the stream不随波逐流

可以看出，strive这个词很严肃，描述了一种艰苦卓绝style的努力或者抗争。

We will strive for peace in the troubled areas of the world.

我们会在世界的动乱地区致力和平。

We should all strive to reunify the motherland.

我们共同努力，实现祖国统一。

6、endeavor n./v.努力；试图

英语释义：an effort or attempt to do something

这个词表示试图或努力做一些什么，不像strive这类词充满了“艰苦奋斗”的意味。

endeavor after wealth(happiness)

努力追求财富（幸福）

We make every endeavor to satisfy our customers.

我们尽全力使顾客满意。

7、apply vt.应用；涂；使专心从事

它的英语释义是：to work at something or study something very hard。

所以可不要以为apply只有“申请，应用”的意思，它还可以表示“勤奋工作，努力学习”哦。

看一下例句：

You will only pass your exams if you really apply yourself (to your work).

你只有全力以赴，考试才能及格。

因此，apply的常见搭配是：apply yourself或者是apply yourself/something to something/to doing something。

8、exert vt.运用；施加

英语释义：exert yourself to make a big physical or mental effort

它指的是：耗费肉体或精神上的努力。

9、extend v.延伸；延长；伸展；扩展；提供；使竭尽全力

英语释义：extend somebody/something/yourself to make somebody/something use all their effort, abilities, supplies, etc.

extend的本义是“伸展，扩展，延长”，就跟明星喜欢跨界挑战自己一样，这也是很努力的意思了。

Tom didn't really have to extend himself in the examination.

汤姆这次考试大可不必那么拼命。
