make sure的用法。

Question

如题所述

Answer 1

make sure to do毫无疑问是正确的。
但是推荐答案中的第二种提法有点危险，很容易让人把do sth当成省略to的不定式作宾补。
其实 完整的说法应该是make sure （that）sb does sth。that常省略，宾语从句中的谓语do有人称、数和时态的变化。
但是要注意，make sure后宾语从句中的时态常不用将来时。如：
Please make sure that the door is locked.请弄准门确实是锁好了。
Are you willing to be a guarantee of your friend's good behaviour, ie undertake to make sure that he behaves himself properly?你愿担保你朋友品行良好吗?
