问题描述:

9.This pair of jeans————— (look) cool.10.The jeans————— (look) cool.请说明理由

looks. 因为THIS pair是单数形式。

9. This pair of jeans looks (因为前面是单数就要在此后面加‘s)' cool.10. The jeans look (因为前面是不止一个物品就不要在此后面加‘s) cool.

9.looks this pair 作主语
10.look the jeans作主语

looks look。第一个 This pair of 代表一条,表示单数,第二个表示复数

This pair of jeans looks cool.指的是这一条牛仔裤看起来很时尚,是单数主语
The jeans look cool.指的是是这一类(品牌)的牛仔裤看起来很时尚,是复数主语
另外look是描述物品给人感官上的影响,所以look均用主动形式表被动语态.
