【题目】—Why didn’t you get on the underground?

— I tried to, but it started moving _________ I could get on it.

A.beforeB.afterC.sinceD.if

【答案】A

【解析】

句意:——你为什么没能坐上地铁呢?——我尝试了,但是在我登上之前,地铁就开始移动了。

考查从属连词。before意思是“在……以前”,引导时间状语从句;after意思是“在……之后”,引导时间状语从句;since意思是“自从”,引导时间状语从句;if意思是“如果”,引导条件状语从句。根据题意可知没坐上地铁的原因是,在坐上之前,地铁就开走了。所以要用before。故选A

【题目】 Later this year, Beijing will start the country’s first driverless(无人驾驶 ) subway trains. The Yanfang Line-connecting part of Fangshan district center-will be the first to try out driverless technology.

According to the experts(专家) in public transportation, the new trains will make the underground railway system(系统) better. They will have an upgraded(升级的)operating system. They will reach 80km per hour and carry more than 1,200 passengers.

They cannot work at all without the help of computers. Just like humans, computers make mistakes-although less often. And like much of technology, it makes many workers lose their jobs.
