题目

关于to I want her to come to my office .tell her to come at once.
I want her to come to my office .tell her to come at once.在这两句话里第一个to可以去掉吗?come to 是词组吗 to come 也是词组吗?

答案

都不是词组
want sb.to do sth.这是个词组（即want her to come）
come后的to应该是个介词,表示come的方向.
tell sb.to do.也是词组（即tell her to come ）
这里come作介词宾语.
