七、 挑战极限原则既然十挑战极限,必然是比较难的,但是并非不可攀!原理:在学生的文章中,很少发现诸如独立主格的句子,其实也很简单,只要花上5分钟的时间看看就可以领会,它就是分词的一种特殊形式,分词要求主语一致,而独立主格则不然。比如: The weather being fine, a large number of people went to climb the Western Hills. Africa is the second largest continent, its size being about three times that of China. 如果您可一些出这样的句子,不得高分才怪!
