问题描述：
Don’t all speak at once!_________,please .A.Each at one time B.One by one time C.One for each
h time Done at a time答案是D为什么不选C
答
习惯：
One at a time.
答
one at a time at a time依次,逐一,每次 就是这么搭配的
答
A.Each at one time,根据语感,这样说不通顺,该语句可能不通;
B:One by one time.one by one就可以表示依次的意思,添加上time后不通.
C:One for each time:这里的time不是时间,而是次数的意思,表示每次一个.
D:One at a time:这里的a time可表示一小段时间.
根据问题语义,需要的是"在一定时间内,只能一个人说话".可选D
