Assure, Ensure 和 Insure 是相近词, 皆含有“确保”的意思。所以单单了解词的释义,并不能帮助你区别它们的用法。
(A) 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:assure somebody of something.
1. He 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。
2. We 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。
1. Weeks 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。
2. Nothing 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)
(B) 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 something/ensure+ that -clause /ensure+object
1. To 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。
2. Registration 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。
(C) INSURE
在美国英语中ensure常拼写为insure, 也含有为了防不测向保险公司付钱投保的意思(to pay money to an insurance company against future disaster)。 英国英语只有后者(投保)的意思。
1. My house is insured against fire.
我的房子保了火险。
2. Are you insured for all risks?
你是不是给自己保了综合险?
试试以下的习题,看看你是否已完全掌握“assure, ensure 和insure” 的用法。
1. If you want to ________ that you catch the plane, take a taxi to the airport.
2. My house is ________ed against fire.
3. No matter how bad you feel about your breakup, you can be _________ed by the fact that your ex feels even worse.

5. _________ that your daughter practices her dance routine.

答案
1. “ensure” – 只有”ensure” 可直接用 “that+clause”,“assure” 不能。
2. “insure” – 只能用“insure”, 这里指“投保”的意思。
3. “assure” – “you can be assured …”, 空格的宾语是代名词 ”you”。”ensure” 不能用这样的结构。
4. “assure” - “assure your son ….”, 空格的宾语是人,”your son”
5. “ensure” -只有”ensure” 可直接用 “that+clause”.
6. “ensure” – 空格的宾语是object “your posts” , 不能用”assure”。
7. “ensure” 或 “assure” 皆可 – peace 和平是抽象名词。
