vt.使确信；使放心；确保

They were assured that everything possible was being done. 已经向他们保证，凡是可能做的都做到了。

Nothing can assure permanent happiness. 没有什么东西能确保永久的幸福。
assure指“使……确信”，不是指“确信”，因此，在使用时要注意在前面加上助动词。 I am assured of his honesty.我确信他很诚实。 I am assured that he is honest.不可以直接说I assure his honesty。
涉及到“保险”时，我们习惯用insure，而不是assure，如insure her car。不过assure也有指“保险”的意思，如assure her life指“为她保人寿险”；
在指“确保”时，ensure的用法比assure更加普遍。 His work assured him a degree of happiness.他的工作确保给他带来了一定程度的幸福感。 His work ensured him a degree of happiness.第二句的用法更为普遍。
Life assurance通常是指到了指定日期或死亡所支付的特定金额的保险，而insurance通常带一定的风险性，若是在指定的日期内没有死亡，过了那个日期死亡的话，是不会得到保险赔偿的。
v.(动词)assure是及物动词,可接名词或代词(不可接that从句)作简单宾语。
assure可接双宾语,这时表物的宾语须由介词of引出; 表人的宾语如置于表物的宾语后,则须由介词to(而非for)引出,如置于表物的宾语之前,则不必搭配介词。
assure后接表物的宾语时,可由that从句或动词不定式充当。
assure不可以直接接带that的从句,它必须先带个宾语,才能接从句。例如: 我能保证他们和我们在一起非常安全。误:I assure they'll be perfectly safe withus.正:I assure you〔her〕 they'll be perfectlysafe with us.
