     Our teacher gave us a task called "secret friends" for the coming week.We were supposed to do nice
things   1   our friends without letting them know who was doing it.We could leave   2   notes or cards
either on their desks or in their backpacks. Before doing the task, with our eyes closed, from a basket, we
   3   a name of a classmate who we were to secretly befriened over the next five days.

presents except me.My friend followed the teacher's   5   without a fault.I received nothing but handmade
cards with nice words about me.

powder, an"old lady" gift.My face went red.

the horrible treatment silently.
     I was sick to my stomach as my  17  words ran through my mind.She had heard everything.How could I
have been so cruel?

had given up her only luxury (奢侈品).
