网友回答
(答案→)coach
解析：
【小题1】根据下文he trains Liu Xiang regularly.他定期的训练刘翔，可知前文意思是：孙海平是刘翔的教练。故填coach。
【小题2】结合语境可知考查短语stand for代表，象征。
【小题3】本题句子中谓语动词不完整，根据原形动词be可知考查被动语态。句意：如果那是你的想法，（我们）不允许你和我们的粉丝一起观看演出。故填allowed。
【小题4】联系下文going swimming with his classmates 可知考查spend用法。spend用于sb spend...on sth或者sb spend...in doing sth（in可以省略），spend的主语必须是人，可以指花费时间、也可以指花费金钱；根据频度副词often可知句子为一般现在时态，主语是单数第三人称，故填spends。
【小题5】根据上文这场篮球比赛持续了三个小时。可知比赛打得非常艰苦。故填tough。
