《牛津初中英语》9A;both;both;二、Both与动词连用时，大多数放在系动词be之后，其它动词之前。 　　 His parents workers. 　　 They reading. 　　 若句中谓语动词包含情态动词或助动词时，both大多放在第一个情态动词或助动词之后。 　　 The bridges be built this year. 　　 　　 kate and Mary gone to England.; 三、Both可与and构成并列连词，连接两个性质相同并在句中作相同成分的并行结构。 　 Both he and his brother are good at English.　　(连接两个主语) 　　;both;　四、含both的句子变为否定时，是将both改为neither。 　;? not only... but (also)...?不但……而且…… ;2. not only... but (also)... 用来连接两个主语时，谓语动词的单、复数遵循“就近原则”，即和but (also)后的名词或代词的数一致。如：;3.not only... but (also)... 连接两个分句，当not only位于句首，前一个分句常用部分倒装来表示强调，而but (also)后的分句仍用陈述语序。如：;4. not only … but also 中的 not only 不能分开使用，但 but also 却可以分开使用。例如：?The area was not only hit by an unexpected heavy rain， but some bridges were also washed away.;5. not only … but also 连接两个并列成分时，可以省略 but 或 also ，也可以把 but also 都省略掉。例如：　I not only heard it but （ also ） saw it.　He was not only compelled（被迫） to stay at home，（ but ） also forbidden（禁止） to see his friend.　She not only finished the task ahead of time， （ but also ） she came to help us.;【注意】使用中注意两点：1、就近。指谓语形式取决于离它近的主语。Not only the students but also the teacher reads English every day.2、一致。not only 与 but also后面所接的词类要一致。She can not only sing but also dance.;【用法小结】　 1. not only … but also 应连接两个相对称的并列成分。例如：?Not only Mr Lin but also his son joined the Party two years ago. （连接两个主语）?I not only play tennis but also practise shooting. （连接两个谓语动词）?He plays not only the piano but also the violin. （连接两个宾语）?They speak English not only in class but also in the dormitory. （连接两个地点状语）; ; ;Bent: Hi Sam, what do you think?
