\"make sure\":通常用于表示在确保某件事情发生之前需要采取某些行动,即“确保”。例如: Please make sure to lock the door before you leave.(离开前请确保锁好门。) I will make sure that the package is delivered on time.(我会确保包裹准时送达。) \"be sure\":通常用于表示对某件事情有把握或确信,即“确信”。例如: I am sure that she will arrive on time.(我确信她会准时到达。)
Are you sure that you want to quit your job?(你确定要辞掉工作吗?)
需要注意的是,“be sure”通常不会带有“to”或“that”引导的从句,而“make sure”则可以带有从句。例如:
I am sure she will come.(正确) I am sure that she will come.(正确)
I will make sure to turn off the lights.(正确)
I will make sure that the lights are turned off.(正确)
总之,\"make sure\"和\"be sure\"都可以用来表示确保或确定,但用法上有所不同,需要根据具体语境进行选择。
