不能用ensure sb do sth,它的句型是:
一、后接名词:
The book ensured his success. 那本书确定了他的成就。
We must ensure continuity of fuel supplies. 我们应该确保燃料供给不中断。
Wash regularly to ensure personal hygiene. 要经常洗澡以保证个人卫生。
Local councils should use their powers to ensure strict observance of laws. 地方政务委员会应当运用它们的权利保证严格遵守法律。
二、后接从句:
I can’t ensure that he will be there in time. 我不能保证他能准时到达。
Please ensure that all the lights are switched off at night. 夜间请务必将所有的灯关掉。
三、后接双宾语:
These pills should ensure you a good night’s sleep. 服下这些药丸可保你睡一宿好觉。
当然也可认为ensure you receive the order within one week 中的you省略了that,这样ensure就是接了一个从句了。
