Question

what is she doing?she ( )be watching TV at home？

Answer 1

A后面加to do 所以排除
B表示可能时候用于一般情况表肯定,例如you can go to the UK by air.
C表示应该有点建议的意味.
D表示猜测的一定.
所以答案选择D
不懂HI 我,7,is
she是第三人称单数，BE也要用三单形势,2,what is she doing？ she (must )be watching TV at home
A ~world like B ~can C ~should D~must
表示她一定在家看电视
不能选A是因为would like to应该这么搭配
can be 没有can be doing这个说法
should be doing很chiengl...,2,both Aand B are wrong answers,both Cand D have some places reasonable. in the case of c,should be doing means"应该。。。。”in the case of d ,must be doing means"一定，，肯定，，，”From that ,I choose the answer C
I hope this can help you !!,2,is
主语是 她 所以是单数的 is,1,what is she doing？ she (is )be watching TV at home,1,D!肯定啊
楼上几个说may 和is,人家都没这选项啊!
问:意思是她在做什么?
答:她肯定在看电视
may语法也对,1,may
可能,1,may
表示猜测可能性,0,选D，must be watching ，她肯定正在家看电视！！！,0,选D，must be watching,0,what is she doing?she ( )be watching TV at home
为什么
A world like B can C should must
求求
