　　Part II：语法学习

　　1.定语从句

　　示例：Byrd now knew that he would be able to reach the South Pole which was 300 miles away.定语从句部分可以简化：…the South Pole 300 miles away

　　2.主语从句

　　概念解释：主语从句，顾名思义，就是作主语的句子。需要注意的一点是：因为放在主语1的位置上的是个句子，所以，有时候会使得1有些头重的感觉，因此，经常会用it进行先行替代，而把从句放到后面。

　　示例：At one point, it seemed certain that their plane would crash.(it是形式上的主语，它替代了后面的主语从句)
