新概念英语第三册习题的问题
第一课中1、What particular evidence persuaded the experts that a puma had been seen in the village?为什么要选
A.The puma had not attack the woman.而不选
B.The woman had described the animal she had seen as 'a large cat'
2、——,it immediately ran away.为什么不选
C.Having been observed而选
B.On being observed
答
1. 问题是在问关于particular evidence about puma，所以回答肯定是要和puma有关。
选项A是以puma为主，陈述了一件事。
选项B是以the woman为主，因此相比较的话，A比较合适。
2. 感觉have been的句型不常用于句首，后面也不跟，
还是以On开头比较说的过去
这个不太确定= =
答
1号问题选择A是因为这个问题问的是puma所以要用puma来回答。
答
第一题中问的是细节,既然是puma肯定会攻击人,但是它没有,而B中的像large cat的还有老虎呢,所以肯定不会选B,再说了,这个B选项也不能算是细节
第二题On在这里表示一旦怎么样就怎么样,这道题的意思是一旦被人发现它就逃走了,所以选B.记住on还有这个用法
