解析:
1.surprised改为surprising.考查形容词.表示"令人惊讶的益处",故surprised改为surprising.
2.important前加an.考查冠词. way是可数名词,所有用an important way表示"一个主要的方式",故important前加an.
3.and改为but.考查固定短语.固定短语Not only…but also..表示"不但…而且",故and改为but.
4.regular改为regularly.考查副词.修饰现在分词exercising应用副词,故regular改为regularly.
5.have改为has.考查主谓一致.which引导的非限制性定语从句,先行词为一个句子的时候,谓语动词用单数.故have改为has.
6.we改为you.考查代词.根据从句 While you exercise可知主句的主语应该是you.
7. what 改为how.考查疑问词.表示"怎样和其他人合作"应该用how.
8.developed改为develop.考查情态动词的用法.和 answer questions more quickly以及think more clearly并列,在情态动词can后,用动词原形,故developed改为develop.
9.for去掉.考查介词.本句表示"无论你在生活中处于哪一步,有一个健康的大脑很有用",此处for多余.故for去掉.
10.exercises改为exercise.考查名词单复数. take exercise进行锻炼.故exercises改为exercise.
