保证担保的英语

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。一、 assure ▲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）二、 ensure ▲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 child's 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。三、 insure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？四、reassure 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 wasn't 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。 ② The 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。
