VOA一分钟英语：辨析动词：assure, ensure, insure

动词 “assure、ensure” 和 “insure” 都以 “-sure” 结尾，它们的发音听上去很像，但含义和用法不同。后面可以直接加宾语代词的是哪个？哪个词和 “保险” 有关？哪个词表示 “确保” 某件事情一定会发生？
 
Hi, everyone! Today's English In A Minute is all about the words assure, ensure and insure. They're often confused because they sound very similar.
To assure means 'to remove any doubt'.
It's followed by an object pronoun. For example:
My friend assured me that he would come to the party.
To ensure means 'to make sure that something happens'.
This verb is not followed by an object pronoun. For example:
I called the bakery to ensure the cake would be ready for the party.
To insure means 'to protect something with an insurance policy'. For example:
I insured my car against theft.
