SAT语法问题 1.SAT语法中两个句子通过逗号连接,中间没有连词行吗?如 The delegates has come so far,they did not want to come back without finishing sth.2.冒号在SAT中怎么用?是类似中文里面的解释说明前一句还是有什么别的用法?3.Harry became the first woman to have piloted a plane across the English Channel and did it just nine years after the Wright brother's first powered flight.这句话里面有两个问题要问首先to have pliloted 这个事情是发生在主句动作之前的 应该没错的吧?再者就是SAT 中IT能不能指代一件事情（to have piloted a plane）?还是仅仅只能指代一个名词?我们老师一直都说可以的 但是我看到网上很多人说都是不
