v.动词
endeavour, attempt, try这组词都有“尝试”或“设法 ”的意思。它们之间的区别是：
1.attempt只用作及物动词,强调“希望成功”,但不一定成功,是正式用语。例如:
We attempted a race.我们试图进行一次比赛。
It would be a waste of time to attempt the impossible.试图做办不到的事是浪费时间。2.endeavour在作“努力”“尽力”解时,是褒义词,指为了完成某事而作出巨大的努力,尤其在面临困难的时候。例如:
The UN is endeavouring to establish peace.联合国正在为世界和平而努力。
Galieo endeavoured to prove that the earth rotates around the sun.伽利略尽力证明地球是绕着太阳转的。3.try既可用作及物动词,也可用作不及物动词,强调通过多种努力,力争取得成功,还有“审讯,审理”的意思,常用于日常口语中。例如:
I don't think I can do it, but I'll try.我认为我做不来那个,但我愿试一试。
If you can't do it the first time, try again.要是你第一次做不成,就再试一下。
Who is going to try the case?谁将审理此案件?
n.名词
endeavours, bid, efforts, exertions, pains这组词都可作“努力”解。其区别是：
efforts着重指动作的本身; endeavours着重作出努力的认真和决心; exertions着重于动作的积极性或剧烈性; bid着重于为达到某种企图而作出的努力; pains侧重为完成某事花费气力。例如:
I will make a great effort to master English.我会努力掌握英语。
The cabinet is making all possible endeavours to bring about national economic stabilization.政府内阁将尽最大努力使国家经济趋于稳定。
I was quite hot and tired after all my exertions.用力干后,我又热又累。
Our Department is making a bid for the interdepartmental basketball championship.我们系正力求夺取系际的篮球赛冠军。For thirty years,Teacher Liu has been taking great pains in educating us.30年来,刘教员一直劳心努力地教育我们。
attempt，try，endeavour，strive这些动词均含有“试图，努力，力图”之意。
attempt较正式用词，侧重已经开始，且希望完成，但常隐含着不一定有预期的结果。
try普通用词，可与attempt换用，但强调努力或尝试，后跟不定式表示努力或争取；后跟动名词表示尝试。
endeavour正式用词，指尽最大努力、认真地克服困难去做某事。
strive和endeavour一样，表示付出巨大努力，但strive侧重劳累与紧张，而不强调努力的结果。
