资源描述
Either的用法:1、Either作形容词,后接单数名词,意为“(两者之中)任何一方的,任何一个的”。 You could choose either half of the pear. 你选择这个梨的哪一半都行。 有时,either+单数名词=both+复数名词,如: We planted trees on either side of the road,=We planted trees on both sides of the road.我们在路两边栽上树。 He saw two films, but he didnt like either one very much. 他看了两部电影,但哪一部他也不太喜欢.On either side of the river there are some small factories. 在河的哪一边都有几座小型的工厂.There are a lot of trees on either side of the street. 街道的两边都有许多树.You may use either book两本书你可以随便用一本。Come on Saturday or Sunday. Either day is OK.星期六或星期天来吧,这两天哪天都行。2、either作代词,意为“其中某一个”,后接名词、代词的复数形式,名词前边加the、my等词;作主语时,谓语动词用单数形式,如: Either of the boys is my brother. 那两个男孩子有一个不是我兄弟。 Either of them must clean the classroom. 他们两人中行一个非打扫教室不可。 Either of them can do the work. 他们两人中谁都能做这工作 Either of the students does well in their studies. 两学生中,无论是谁学习都不错Do you like the two books? 你喜欢这两本书吗? No, I dont like either. 不,哪一本我都不喜欢Either of the knives is useful 两把刀都有用。Do you want tea or coffee?你要茶还是咖啡?Either is OK.哪一种都行。Is either of your parents coming to see you next week?下周你父亲或母亲要来看你吗?Either of the films if good. (作主语,谓语用单数)两部电影中有一部不错。He wrote to either of them.(作宾语) 他给他们中的一个人写了信。3、either作副词,用于否定句中,意为“也”,常位于句末并用逗号隔开,例如: If you dont go, I wont, either.He doesnt like meat. I dont like it, either.Her father cant help her with her English, and his mother cant either.注意:在表示“也”时,either用于否定句中,在肯定句中,则用too或also. 4、either作连词,构成搭配eitheror“要么要么”“或者或者”“不是就是”。either作连词时,与or 连用,构成并列连用,连接语法结构相同的单词、短语或从句(它们可充当句子的多种成分,如主语、宾语、谓语或表语等),当连接两个主语时,谓语动词要和最近的主语(即or后的主语)保持一致,例如: Either he or I am right. 不是他对,就是我对。(主语) You can either go with me or stay at home. 你要么跟我走,呆家里。(谓语) You may choose either the green shirt or the blue one ,but you cant take both of them. 你可以选择绿色的衬衫或蓝色的衬衫,不能两件都拿。(宾语) Either your brother or your father has to stay there today, going on night patrol.We can eat either cakes or bread for breakfast.早餐时我们不是吃蛋糕就是吃面包You may buy either a sweater or a jacket for his birthday. You either go right now or stay here,saying nothing. The man is either a doctor or a teacher. 那人要么是一名医生,要么是一名教师Theyll come back from Hong Kong either today or tomorrow. (状语)注意:有时,可将由“or”相联系的两个并列的结构相似的句子,改写为由“eitheror”构成的句子,例如: Lily may go with you ,or Lucy may. Either Lily or Lucy may go with you . 莉莉或露西和你去。 My father will go to the evening party, or my mother will. Either my father or my mother will go to the evening party. 不是我爸爸就是我妈妈将参加晚会。 5、neither与either的某些结构之间的相互转化。 在either作副词,表示“也”时,这时如是所在的句子的前后结构是并列的,那么可以与neither引起的倒装句和neither作连词时的句子结构之间相互转换,如: He wont spend his holiday anywhere else, and his wife wont, either. 他不到其它地方度假,他妻子也不去。 =Neither he nor his wife will spend his holiday anywhere else. 他和他妻子不到不到其它地方度假。 Liu Mei doesnt want to go home on foot, ant Xiao Hai doesnt, either. 刘梅不想步行回家,小海也不想。 =Liu Mei doest want to go home on foot, neither does Xiao Hai . 刘梅不想步行回家,小海也不想。 =Neither Liu Mei nor Xiao Hai wants to go home on foot . 刘梅和小海都不想步行回家。 I dont speak French. She doesnt, either (Neither I nor she speaks French) 我不会讲法语,她也不会讲法语。 If she wont go, neither shall I (If she wont go, I wont, either) 要是她不去,我也不去。注意:如果either此时所在句子前后不是并列关系,则不能转换,如前例:If you dont go to Changsha, I wont, either.不能转换,因为前句子为条件状语从句,与后句不是并列关系。 neither和either的用法 1共同点: 1)它们都可用作主语、宾语和定语。例如:Neither of the books is good.(主) He phoned neither of us yesterday.(宾) Neither way is correct.(定) I dont think either of them is at home.(主) Here are two knives.You can take either of them.(宾) There are shops on either side of the street.(定) 2)Neither和either作定语时,其后的名词都用单数。例如: Neither book gives the answer. There are tall buildings on either side of the road. 2不同点: neither是表示“两都不”的否定说法,而either是表示“两人或两物中任何一个”的肯定说法。 注意: .either作为副词表示“也”,不同于too,also。either通常用于否定句的末尾,too通常用于肯定句的句末;而also通常用于肯定句和疑问句中,其位置一般用在to be之后,其它动词之前。如: Tom has been to Beijing.Mary has been to Beijing_(96江西) A.neither B.either C.too D.also 此题应选C。 She is also a teacher. She also likes singing. I cant speak French.My sister cant speak French,either. .neither作为副词表示“也不”,常常用于倒装句的开头,紧跟在一个否定句后面(当然nor也可以这么 用)。那么,如果是肯定句呢?我们要用so,依然是倒装语句。例如: I cant sing an English song.Neither can he. I can sing an English song.So can he. 还应注意neither和so后面的助动词和情态动词其后的主语在人称、时态方面保持一致。 .neither和either在句中作主语时,谓语动词必须用单数形式。如:(none作主语,则可单可复) Neither of them knows Japanese. Either of them knows English. .neither本身表示否定,其后不能再用否定式。如: 两个答案都不对。 【误】Neither answer isnt right. 【正】Neither answer is right. .either与not连用表示“两者都不”,此时相当于neither。如: I dont want either of them=I want neither of them.我两个都不想要。
