Question

—_____ swim in the river?
— oh, no. Our teacher told us ____ here. It’s dangerous.

A．Why don’t; not swim	B．Why not; not to swim
C．Why not; don’t swim	D．Why don’t; don’t swim

Answer 1

B

试题分析：为什么不在河里游泳，why not do sth后面加动词原形，表示建议通常与hou about doing sth what about doing sth  why don't you do sth进行同一句转换肯定的表达是tell sb to do sth 告诉某人去做某事，否定的表达是tell sb not to do sth告诉某人不去做某事。故选B，根据下句老师告诉我们不要在那游泳。
