介宾比较 A do sth of C1 by D1 than of C2 by D2. 注意一定要是介宾才能直接跟在than后面
例子 The clothes inside the store looked more appealing than outside the rocks. 错,不是介宾比较
The clothes inside the store looked more appealing than did those outside the rocks. 对
The clothes inside the store looked more appealing than outside the rocks.
这句话之所以有错误是因为有歧义。
可以理解为
1、The clothes inside the store looked more appealing than those outside the rocks.
比较的是two sets of clothes
2、The clothes looked more appealing inside the store than outside the rocks.
比较的是the same clothes
