be sure that与 make sure that的区别________that the TVand the light are turned off when you leave.填be sure 还是make sure 为什么？

差不多。第一个是对某事有把握

第一个是相信某事和第二个是核实某事

be sure that与make sure that在意义上没有区别 都是指“确定.....”
只是用法不同
前者用于有BE动词的情况
如 I am sure that ..../He is sure that
后者不能在make sure 前面加BE动词
如 I make sure that ...
He make sure that....

2者翻译成中文区别不大
不过 be sure that 表状态 如 i am sure that it's you. 我确定那是你
make sure that 表动作 如 I'll make sure that it's you. 我会使那个是你.

be sure that是一定会,肯定会的意思,如： I'am not sure（that）she will pass the test. make sure that是确认,查明的意思,如： Please go back and make sure that all the lights are off.碰巧和我举得例句类似,...

make sure that动词
be sure that表状态
例如 Make sure that you have closed the door.
He was sure that he had closed the door.
