几个英语句子的分析
It was easy to tell the natives from the tourists.这里的tell是交流的意思吗
It turned out that the child I thought was a girl was a actually a boy.这里为什么是两个a呢,我觉得应该是was actually a boy或是was a actually boy啊
Then it became more like French because those who ruled England spoke French.这里的who是什么成分啊,可以删去吗
（这是最后一个）The reason why he didn't pass the exam was that he was nervous at that time.我觉得第一个that应换成because啊,应为这个表语从句是表原因的啊.
十分十分感谢、
