题目内容
17."Be patient,boys.You won't find out the answer ________ Mr.Lee's talk ends,"said Mr.B lack.( )| A. | If | B. | until | C. | as soon as |
分析 "孩子们,耐心点.如果Lee先生的讲话结束了,你们就找不出答案了."Black 先生说道.
解答 答案;A 根据You won't find out the answer 你们将得不出答案,________ Mr.Lee's talk ends,lee先生讲话结束,可知这是if引导的条件状语从句,表如果,时态遵循主将从现;意为:如果Lee先生的讲话结束了,你们就找不出答案了;B until 意思是直到,放在此处不合适,C意思是一…就…放在此处语句不通,故选A
点评 此题考查考生if引导的条件状语从句的理解,要注意在这个条件状语从句中要分清主句和从句,还要注意如果主句用将来时,则从句用一般现在时.
