each boy and each girl做主语时,看成是单数,所以填looks。who是定语从句的先行词,代表children ,填have。主语是John,as well as做并列主语,不影响Jone这个第三人称单数,填takes。by是介词,后面跟traveling 。places of interest,名胜古迹的意思,固定用法。When and where to go是不定式短语作主语,看成单数,后面有个yet,应该用现在完成时,has not decided。California 后面用where引导定语从句。one-third of state看成单数,用is。the majority of citizens是复数,填are。try one's best后面要跟to do,所以填to prepare。
1.each boy and each girl作主语,谓语动词用单数。根据句意可知此处用现在进行时,系动词用is。
2.who替代先行词children,所以用复数。
3.as well as连接两个名词作主语,谓语动词应根据前面的名词确定。故该空用单数。
4.根据句意可知此处用被动形式be done。
5.places of interest名胜古迹。
6.从句作主语,看成单数。根据yet可知此处为现在完成时。
8.分数、百分数作主语,谓语动词单复数取决于其所替代的名词。
9.根据the citizens可知,用复数。
10.此处为不定式作目的状语。
