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。
㈠ 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) ㈡ 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。 ㈢ 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? 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 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。
