祈使句时 是to be sure 还是 be sure

祈使句时 是to be sure 还是 be sure be sure to do的主语是人还是it? Be sure to close the windows是不是祈使句?可不可以写为Being sure to close the windows be sure to后面是加名词还是动词啊 这个to是介词还是不定式? be sure of 和 be sure to “May God be with you”是陈述句还是祈使句? be sure toI am sure the 3.4 to 4 oz will be fine.请问是要3.4的还是4的,又或者是3.4-4的呢? be sure to do 用Be sure to、Be sure to do 、Be sure of、Be sure that 造句 Before you visit Mr zhang this afternoon,__ that he will be at home.答案是选A.making sure 还是B.make sure 看上去，选B更好，祈使句。但是选making sure 动名词作主语，在语法上说也没错吧。 英语语法问题 be sure to do用法you are almost sure to get it这个be sure to do 中的 to do 是不定式短语作 sure的宾语吗?难道to do 是不定式短语作 sure的状语 他们不能确信是they are not sure还是they can‘t be sure?为什么 be sure to do sth. be sure to go there they are sure to be I'm leaving now ,_______ you turn off the lights A.To make sure B,Make sure C.making sureI'm leaving now ,_______ you turn off the lightsA.To make sure B,Make sure C.making sure这句话是祈使句吗?什么时候句首用To make sure 或making sure 这是一个动词时态语态的问题.be sure/make sure/take care +宾从 时 宾从中是不是要用一般现在时,再补充一句。sure/make sure/take care用一般现在时 还是后面的宾从用一般现在时。 make sure,be sure of ,be sure to do,for sure的区别
