问题描述:

--hey man you can not cross the street now you have to wait --- the traffic lights turn green
--oh sorry and thank you
a\ when
b\ after
c\ until
d\ while
说理由!

b.after

只有not ...until 这句话中没not

A项,when ,则表示当灯变绿时你必须等待。
B项,after,则表示当灯变绿之后。。。。
C项,not。。。until固定词组且符合题意
D项,灯变绿是一个瞬间的动作,而while则表示一个连续的过程。
故选C

选C until直到
句子意思 --嘿 男孩 现在你不能穿过街道 你必须等待 直到交通指示灯变为绿色
--哦 抱歉

B,until,一直等直到灯变绿,until译为直到……为止,其它选项你可以代入翻译一下,都不对的
