—— no friction between the surface of the road and our feet,we could not walk at all. A If there was B Were there 答案选的是A 、B为什么不对了。。 没搞清楚的不要乱来一气 我承受能力不好 脑袋都给你们搞晕了。
此题就是选B。 从后面的主语could not walk来判断,这是个虚拟语气的句子。当if引导的非真实条件句中含有were, should, had时可以把if 省略,把were ,had ,should 提前。 所以这句话正常语序是 if there were no friction(如果没有摩擦的话) 又如:Should it rain tomorrow, we would not go outing. Had he followed my advice, he would have passed the exam.
这道题考的是there be 的用法,一般be用单数还是复数由他后面所接的词的单复数决定。即be的数与后面的名词一致,若be后是两个或多个并列的名词,be则与靠得最近的那个名词的数一致。 friction是不可数名词,因此选B。期中between the surface of the road and our feet做定语修饰friction,对其做解释说明。
