                                                                  What's Cool?

                                                                  By Maria Lee

     This week, I asked students about fashion (时尚). I showed each student six things and asked them

about each one. Some of their answers were interesting. Here are their likes and dislikes.

     Judy Smith likes the key ring (钥匙环). Her friend Jeff says he can't stand the scarf (围巾). "It's for

moms!"he said. William Jones loves the wallet, and his classmate Gina Taylor loves the watch. (Her best

friend Ann Rice doesn't mind the watch, but she really likes the sunglasses!) Jerry Green also likes the

sunglasses (太阳镜).

     And the coolest (最酷的) thing was the belt. Everyone loved it!
