网友回答
(答案→)am--was
解析：
【小题1】当我7岁的时候，用过去时：am--was
【小题2】考查介词短语：between…and….
【小题3】No. 20 MiddleSchool前面不能加the
【小题4】这里用included是做谓语
【小题5】几门学科是并列关系：or--and
【小题6】it—them，them指代English and puter
【小题7】时间是Last year，had去掉
【小题8】listen是不及物动词， 后加to
【小题9】be动词用的是are所以运动是复数 sport—sports
【小题10】skate--skating ，skating是动名词和swimming是并列的
