It was the break time, and the students was playing on the playground. Jack was playing the basketball with a group of boys while Lily told him that the headmaster wanted to see him. Jack seemed confusing. He thought, “I did something wrong. Why did the headmaster ask me to his office?” Then he walked there nervously. In his surprise, the headmaster praised him, as he learned from some teachers that Jack usually volunteered to helping others. The headmaster told Jack he had set example to other students. Heard that, Jack was very happy. He promised the headmaster that he will continue to be a caring student.

试题分析： 通过本文的阅读和改错，考查学生的固定搭配和时态和非谓语动词的用法、连词、冠词的区别等。

【1】was playing → were 考查主谓一致。 the students 是复数，后面的be动词一个用were 和playing 构成过去进行时。

【2】playing the basketball 去掉the 考查冠词的用法。 球类运动前不用冠词，打篮球: play basketball。

【3】while → when 考查固定用法。 be doing when 是固定用法，意思是：某事正在发生这时……。

【4】confusing → confused 考查形容词的区别。confusing令人困惑的；confused感到困惑的。句意：Jack似乎很困惑不解。

【5】something → nothing 考查代词的用法。我没有做错事。“没事”用代词：nothing。

【6】In → To 考查固定词组。 to one’s surprise 的意思是：令人惊奇的是。

【7】helping → help 考查动词的用法。volunteer to do ，to后用动词原形。

【8】example前加an 考查名词的用法。example 是可数名词，set an example to 给……树立一个榜样。

【9】Heard → Hearing 考查非谓语动词。Hear 由主语Jack发出，应该用-ing形式。-ed 表被动。

【10】will → would 考查时态一致。主句动词promised是过去式，所以宾语从句应该用过去将来时，would 加动词原形。
