There was a sign by the river bank warning people to( )the thin ice.

问题描述:

There was a sign by the river bank warning people to( )the thin ice.
A.keep off B.keep out C.keep away D.keep on

A
原句的意思:在河岸旁有一个提醒我们( )冰面的标志.
四个答案意思分别是:避开、躲开;留在(某处)外面;与.保持距离、远离;继续
根据意思 A C 都可以 但 keep away 后要加 from 才能再跟名词
所以选A
有问题再问吧 希望有所帮助
