bear，endure，stand，tolerate都含有一定的"忍耐、忍受"之意
在表示忍受pain，suffering，hardship等时，在许多情况下这四个词可以互换使用；通常与can或cannot连用
bear 强调忍受者对痛苦、忧虑、烦恼以及责任的承受力（常用于否定句中）endure (=bear bravely)指经受长期的艰难、困苦或折磨而不屈服，强调持久力和意志坚强（常用于否定句中）
stand 强调不屈不挠或经受得起（常用于否定句中）
tolerate指忍受某人或某种行为而不反抗，语气最弱（即可用于肯定句也可用于否定句）
He quietly endures the pain of a loveless marriage.他默默地忍受着没有爱情的婚姻的煎熬。
The sorrow was almost more than she could bear.她几乎忍受不了那种悲伤。
I can’t stand hot weather.我受不了热天。
A government that refuses to tolerate opposition cannot last long.
一个不听取反对意见的政府是不会长久的。
It’s hard for people to put up with that kind of treatment.人们很难忍受那种待遇。
assure，ensure，insure与reassure 区别
assure，ensure，insure与reassure这四个单词可谓是形近意似，但用法却不无区别。
㈠assure
▲assure用来表示向某人保证某事将要发生，既可以用来确证某事，也可以表
示使某人确信（If you ASSURE a person of something，you promise them or tell them that）。assure的宾语通常是人或人称代词，所以不能直接搭用that －clause。其常用结构为：assuresb．ofsth．／as-。
①He assured us of his ability to solve the problem．他向我们保证他有能力解决这个问题。
②We booked early to assure ourselves of（getting）good seats．我们及早订座以保证我们能得到好座位。
▲assure后还可跟抽象名词作宾语，此时与ensure同义，表示确保。
①Weeks of practice assured ／ensured success in the match．几个星期的训练确保了在比赛中获得成功。
②Nothing can assure permanent peace．没有什么能确保永久和平。
▲assure在英国英语中作为专业术语，可表示投人寿保险。to insure ／assure against death投保寿险（life assurance ／insurance人寿保险）㈡ensure
▲ensure的意思是使某行为或某件事的结果得以保证，即确保某事发生（to make sure that sth．happens）。ensure后可以直接跟that-clause，并可以用复合宾语。常用结构为：ensure sth．／ensure ＋that －clause ／en-sure ＋obj．（i）＋obj．（d）
①To ensure the childs quick recovery，the doctor gave him an antibiotic．为使这个孩子尽快恢复，医生给他打了一剂抗生素。
②Registration ensures delivery of mail．挂号寄邮件保证会送到。
▲ensure也可以表示确保安全，免遭伤害。To ensure freedom against tyranny反对暴政，维护自由
▲在美语中ensure常拼写为insure。㈢insure 意思是为防不测向保险公司付钱投保（to pay money to an insurance company against future disaster）。
①My house is insured against fire．我的房子保了火险。
②Are you insured for all risks？你是不是给自己保了综合险？
㈣reassure表示安慰忧虑不安的人，使其安心，放心，恢复信心（to comfort someone who is anxious and make him ／her free from fear or wor- ry；
to bring back confidence to．．．）。常用结构为：reassure sb．（about sth．）／reassure sb．＋that-clause
①I was worried that my work wasnt good enough，but the teacher
reassured me（about it）．我担心我的作业不够好，可是老师却让我放心。
②The captain reassured the passengers about the strength of the
ship．那位船长向乘客保证船很坚固，要他们安心。
