Answer 1

I often follow my mother ( to visit ) TV her friends.( 因为 follow sb. to do sth. )

The police ( is ) looking for the missing boy in the foerst.(一般来说是正在进行时；如果是阅读理解里的题目的话，过去进行时比较多，那就应该用was了）

(What) ( was ) the tutor ( doing ) when you asked me to play tennis with you?
(提问的句子是件事情嘛，所以用what提问，然后把be 动词提前，再看提问的句子是doing sth.，所以就doing啦）

语法什么的，你该好好掌握一下哦O(∩_∩)O！

Answer 2

第一道题目你是不是少打了？
第二道：选C。警察前加定冠词表示复数，排除A、B。因为没有明显表示时间的单词，所以应该用现在进行时。
第三道：What was doing 这个很明显啊。。。当你要我和你一起打网球的时候你的家教在干什么？
