根据句意用所给词的适当形式填空。
【小题1】 Jack usually checks his test paper carefully (careful) before handing it.
【小题2】 Mary thinks studying (study) grammar is a great way to learn a language.
【小题3】 –What happened (happen) to Dave on April Fool’s Day? –He was fooled by his friends.
【小题4】 Students in this school want to be volunteers (volunteer) during this winter vacation.
【小题5】Liu Li was the winner (win) of last year’s English Speech Competition in our school.

解析：【小题1】通过题干可知，本空是修饰动词check的，故应该用副词carefully。【小题2】根据题干，本句的意思是“玛丽认为学习语法是学语言的好方法。”本句应该是动名词做主语的，故用studying。【小题3】通过He was fooled by his friends.可知，本句应该是过去时，故填happened。【小题4】根据主语 Students可知，此处的“志愿者”volunteer应该用复数形式，故填volunteers。【小题5】根据题干，本处应该是表示人。本句的意思是“刘丽是我校去年英语演讲比赛的获胜者。”故填winner。

谢谢了
