问题描述：
横线上It's good______ all my teachers and friends again.
横线上应该填什么?
选项：to see
to look
to watch
see
请讲明原因!
答
to see
it is +adj+to do sth.
答
see 代表看到，watch代表注意，注视
我们选择用see
句子里 to see all my teachers and friends again
是it的同位语，我们可以这么说：
to see all my teachers and friends again is good
答
to see
be good to do sth
见到嘛,watch 和look都比较短暂呢.
