Answer 1

分析 高分句型一：
To begin with，Wechat is a relative cheap way of communication，which cuts down a great deal of the cost of making a phone call
高分句型二：
There is no doubt that Wechat will improve as time goes by．
句型一 which cuts down a great deal of the cost of making a phone call．该句是一个由which引导的非限制性定语从句，which在句中充当主语，替代前面整句话内容．
句型二 There is no doubt that Wechat will improve as time goes by．该句使用了一个固定的句型：There is no doubt that…是毫无疑问的…而that后面是一个同位语从句，同位的名词为doubt
