Five students went out for a one-week trip in the countryside. When they returned, the group leader wrote a report about each student. _

A. He was getting on very well until he hurt his foot on the third day. He didn’t take part in most of the activities in the second half of the week.

B. She enjoyed herself, but found it very difficult to get up in the morning and often kept the others waiting.

C.  A future leader. He always wanted to be first to try a new activity. He was very kind andhelpful to those who had difficulties.

D. She was very shy and easily frightened. It was hard for her to make friends. I’m not sure if she enjoyed the trip very much-

E. He took part in only a few activities.  He missed home very much.  He gave me the impression (印象) — he didn’t really want to be with us.
