What does Bill want to know_.
问题描述：
What does Bill want to know_.
A where does she live
B where she live
C how old are you
D how long does it take to get to school
答
A Where does she live但是老师讲了，是B,但不知道原因What does Bill want to know ,后面引导的是以where开头的宾语从句，宾语从句中主句（即句中What引导的那一部分）和从句（即where引导的那一部分）的时态应保持一致。但如果从句中表示的是客观现象，那就要用一般现在时表示。其实不用想得那么麻烦，比较四个答案，只有第二个是陈述句形式，其他的都是疑问句形式，而作为宾语（从句），不能用疑问形式，要用陈述句形式，即谓语动词要放在主语的后面。Nina wants to know_
A Where does Mike live
B where does Mike live in
C where Mike lives
Dwhere Mike live同理，可以先排除A和B，而Mike是第三人称，后面的动词要加S，所以选C
