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？
用法总结
1. 动词 “assure” 用来表达 “（为消除疑虑）向……保证”，后面接宾语代词，以表明向谁保证。
- I assured him that the package would arrive on time.
- She assured me that the work would be done properly.
2. 动词 “ensure” 的意思是 “确保（某事会发生）”，后面不接宾语代词，而是直接说明事件。
- I ensured the package arrived on time by delivering it personally.
- She ensured the work was done properly by hiring the best workers.
3. 动词 “insure” 的意思则是 “给……上保险”。
- I insured my house against fire and burglary.
