EITHER的详细用法
either是个常用词,也是高考经常考查的词之一,它既可作代词,也可作副词.
either的用法比较灵活,现归纳如下:
1.either用作代词,意为“(两者之中)任一、任何一个”.在句中可作主语(此时句中谓语动词用单数)、宾语、表语和定语(作定语时,有的词典把它称为形容词;either作定语时,只能修饰单数名词.)如:
Either (of the books) is popular with the students.
(两本书)随便哪一本都受到同学们的欢迎.(主语)
I have bought two cakes��you may have either.
我买了两块蛋糕��你要哪块都行.(宾语)
The books were either works on travel or detective novels.
这些书要么是旅游方面的书,要么是侦探小说.(表语)
You can park on either side of the street.
在街道的哪边停车都可以.(定语)
2.either用作副词,用于否定句作“也”解释,通常置于句末.如:
I don”t like the red shirt and I don”t like the green one either.
我不喜欢这件红衬衫,也不喜欢这件绿衬衫.
As for me,I shall not return there either.
如果是我,我也不会回到那儿的.
either还可用来强调含否定意义的短语.如:
I know a good ltalian restaurant.It”s not far from here either.
我知道一家意大利餐馆,离这儿并不远.
3.either可以构成短语,either…or…,意为“或……或……、不是……就是……”,在句中连接两个并列成分.如:
Either you or Tom has done it.(连接并列主语)
不是你就是汤姆做了这件事.
You may either stay at home or go there with us.(连接并列谓语)
你既可以待在家里也可以和我们一道去.
注:在连接两个并列主语时,谓语动词必须在人称和数上与靠近的主语保持一致.如:
Either you or the headmaster _______ the prizes to these gifted students at the meeting.
A.is handing out B.are to hand out
C.are handing out D.is to hand out
Either the headmaster or you _______ the prizes to these gifted students at the meeting.
A.is handing out B.are to hand out
C.are handing out D.is to hand out
4.either的反义词为neither“(两者)都不”,either…or…的反义词组为neither…nor…“既不……也不……”.如:
You can drop either of the two courses.
你可以放弃这两门课程中的任何一门.
You can drop neither of the two courses.
这两门课程中的任何一门都不能放弃.
Either you or he has made the mistake.
不是你就是他犯了这个错误.
Neither you nor he has made the mistake.
犯错误的既不是你也不是他.
either…or…表示两种可能性中任选一种,其后面必须连接两个相同的句子成份.例如:
The sentence can be either true or false.句子要么是对的要么是错的.
You can either come with me or walk home.
你要么跟我一块去,要么走回家去.
Either mum or I cook supper.要么我母亲要么我做晚饭.
neither…nor…连接两个相同的句子成分,表示否定的意思.动词的单复数形式与nor后的单词主谓语相一致.例如:
Neither Li Lei nor Wang Hai was there.李雷和王海都不在那里.
I neither watch TV nor listen to the radio.我既不看电视也不听收音机
