【解析】

1句意::她妈妈要求她不要玩太多的电脑游戏。如果她这样做,她妈妈将会生气。do动词,做;does是其第三人称单数。在含有if引导的条件状语从句的复合句中,主句用将来时,从句用一般现在时;本句主语为she,动词用第三人称单数形式does。故填:does。

2句意:我认为你工作了一周后应该好好休息。have动词;固定搭配have a good rest,意为好好休息”。should为情态动词,后用动词原形。故填:have。

3句意:我昨天打篮球很开心。play动词,打;have a great time doing sth."做某事很开心"。故填:playing。

4句意:地球上如果没有水和空气,将会发生什么事情?happen动词,发生。在含有if引导的条件状语从句的复合句中,主句用将来时,从句用一般现在时。故填:will happen。

5句意:为了保持健康,最好每天锻炼。exercise 动词,锻炼;本句句型为:It’s +形容词+(for sb).+ to do sth., 意为(对某人来说)做某事是怎么样的。”it在此为形式主语,动词不定式为真正的主语。故填:to exercise。
