Question

The teacher with many students have gone to Hainan Island
为什么把 have 改成 has?而不是把 with 改成and?
The number of the students in our class are more than 60
为什么把 are 改成 is?而不是把后面个 the 去掉?
We have learned English since over two years
为什么吧 since 改成for?而不是把 over two years 改成two years ago?

Answer 1

1.with 连接两个主语,谓语动词用就远原则,即根据 the teacher 来确定,所以不能用 have 哦.
2.The number of ...作主语,表示：……的数量 ,看作单数,所以动词 用is ,而不用are .
3.since +时间点 ,for +时间段.而 over two years 是时间段,当然要用 for 啦.
for two years =since two years ago
