英语单词区分：ensure;insure;guarantee;assure词义和用法上的区别
The Car Club couldn't_to meet all the demands of it's memebers.
A.ensure B.insure C.guarantee D.assure
请以此题为例子,做一下分析,

应该选A,具体的辨析如下：
ENSURE,
INSURE
and ASSURE are
interchangeable in many contexts where they indicate the making certain or
inevitable of an outcome, but ENSURE may
imply a virtual guarantee , while INSURE
sometimes stresses the taking of necessary measures beforehand , and ASSURE
distinctively implies the removal of doubt and suspense from a person's mind
.
大意是ensure经常保证的是一种虚拟的非实物的东西,比如安全什么的；insure一般是通过提前采取一些必要的措施来达到保证的目的；assure特指扫除某人的疑虑或疑问这一类范畴.
希望对你有用.
再问： 不定式作宾语就一定要用guarantee么？
再答： 词典上的例句是这样的的。
