Unit1Know yourself (Grammar )（含练习答案）
Both可作形容词、代词或副词用，意思是“两个”、“双方”、“两个都”。在句中可作主语、宾语或同位语。如：Both are right.(主语)I like both.(宾语) Both pencils are mine.(同位语） 一、Both和both of后都可接复数名词，构成名词词组。
Both后的名词前可有定冠词、指示代词或物主代词作修饰限定，也可没有；both of后的名词前却一定要有定冠词、指示代词或物主代词作修饰限定。
both(the these，her) childrenboth of the(these，her)children； √both of children。× Both of后可接人称代词宾格，both后则不可；但人称代词宾格后可接both。 both of us(you，them)√both us(you，them)× us(you，them)both√ 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 are both workers.They both enjoy 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 bridgesmust both be built this year.kate and Mary have both 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) She can both dance and sing.(连接两个谓语动词) Mary is both kind and beautiful.(连接两个表语) 四、含both的句子变为否定时，是将both改为neither。Both of the boys are clever. Both of the boys are not clever.不完全否定,并不是两个男孩都聪明(一个聪明一个愚笨)。 Neither of the boys is clever.两个男孩都不聪明。 含both…and…的句子变为否定句时，将both…and…改为neither…nor..，连接的两个部分若是名词，可以是单数，也可以是复数。
I know both the man and the woman.I know neither the man nor the woman Both beats and birds would have the bat as their friend. Neither beats nor birds would have the bat as their friend. Not only... but (also)...不但……而且……
1. not only... but (also)...在句中常用来连接两个对等的成分，also可以省略。如： He is learning not only English but (also) French. （连接两个宾语） 他不但在学英语，而且还在学法语。
She speaks Russian not only in class but (also) at home. 她在课堂上和家里都说俄语。 （连接两个地点状语）
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：Not only Zhou Xia but also her parents are fond of watching football matches. 不但周霞，而且她的父母都喜欢看足球比赛。
Not only you but also he is tired of having one examination after another.不但你，而且他也讨厌一次接一次的考试。
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：Not only is the teacher himself interested in foreign films，but also all his students are beginning to show an interest in them. 不但老师自己对外国电影感兴趣，就连他所有的学生也开始对外国电影感兴趣了。 Not only does Miss Li like music, but (also) she likes sports. 李小姐不但喜欢音乐，而且还喜欢体育。
Either ---or ,either : 指两者中的任意一个。either...or...意为\或者……或者……；不是…就
是……\之意。表示两者之一，连接句子中两个并列的成分Either you or I can go there tomorrow. SubjectI either stay at home or go shopping. VerbWe could choose to eat either noodles or rice . object They are going there either by train or by air. adverbial Either用于句末，表示否定的“也”，类似too ,Either---or---就近原则
Neither---nor,neither: 指两者中没有一个，全否定。neither...nor...表示\既不……也不……\。其含义是否定的，可连接任意两个并列的成份。Neither Jim nor Tom likes football.He can speak neither Japanese nor Chinese.Neither---nor---就近原则
Neither/Nor + be 动词/情态动词/助动词+主语” (某人也不）
表示前一句中主语的否定情况也适用于后者，前后两句的主语是不同的。
