Make sure 可以表示检查某件事是否属实、是否正确，也可以表示确保事情一定发生。前一种用法是核实情况；后一种是对结果负责。Make sure you lock the door 就是在提醒“别忘了锁门”。

修改原因
修改前Make sure you will turn off the lights when you leave.
修改后Make sure you turn off the lights when you leave.
关灯还没发生，容易让人想到 will。但在 make sure 引出的这条未来行动提醒里，用一般现在时：make sure you turn off。修改删去了 will。
注意与 be sure 区分：I'm sure she'll come 是相信她会来；Make sure she comes 则是要求确保她到场。在作文中，make sure 可以换成 ensure：Schools should ensure that every child can use a computer。
