解答

1,alter有改变,改动的意思,但是alternate是交替,轮流的意思,这句话的意思是史密夫教授和布朗教授轮流上演讲课.
2,represent是代表的意思,而且好像一般偏重代表人多一点的,在这里不太恰当,reveal的意思是揭露,披露,也不对,而express的意思是表明,表达,在这里这句话的意思是地图上的那些蓝线指的是道路(表明蓝色线是道路)
3,这句用的是现在完成时,has/have+v过去分词,这句话没有什么特别要说出的,只要分清put into和pull into的意思就好了,但是这里我也不懂为什么不选put,put更准确一点,所以这题没有办法回答你.
4,be based on是固定搭配,根据,以…为基础；建立在…基础上的意思.
