I am a person who can get angry   26 . But after  27 a passage from my English teacher, things have changed  28 . I am studying at a boarding school, so I have to learn  29  how to study well, but how to get on well with others. Some of us are  30  while others are quiet. So it is  31 that people have problems and arguments.

Smiling at others is the easiest way to stop argument. Another way is to think  32 your ideas are right before having an argument. If others’ ideas are really not good, keep and open  33 . Try to forgive（原谅）them. Having a friend is  34 better than having an enemy after all. Also,   35 point out others’ mistakes  36 . If you really want to help them, send a letter  37 . On the other hand, if someone points out your disadvantages, don’t  38 . Just think this is a person who really wants to help you and make friends  39 you. Remember: Forgiving makes life  40 .

When he heard the name of the  【小题5】  which she came from, a strange light filled his eyes. As soon as he walked into her room, he got to know her at once. He did his best to  【小题6】  her. Then he gave special attention to her. After some time she got well.
Dr. Kelly asked for her final bill before she left hospital. He    【小题7】  it, then wrote something on it  【小题8】  it was sent to her. She was afraid to open it, for she believed it would cost the rest of her life to   【小题9】  for it all. But   【小题10】  she opened it, and read these words on it: Paid in full with one glass of milk.
