all, both, every, each, either, neither的区别.doc

all, both, every, each, either, neither的区别1.all, both同属前位限定词，但all可以与三类名词搭配，both只能与复数可数名词搭配，从意义上讲both指两者，all指三者或三者以上。如：How much time will you take for all this work?All children can be naughty sometimes.I got both these vases in Spain.Both cats are asleep.all和both用于否定时表示部分否定。例如：I cannot promote both of you.我不能使你们两个都提升。All flowers in his garden are not red.他花园里的花并非都是红色的。Both (of them) are not my brothers.他们两个之中，只有一个是我的兄弟。另外，表示部分否定的词还有every (everyone)。例如：Every man can not be a poet.并非人人都可以成为诗人。要表达全部否定要用none / no (nobody) , neither, either等。例如：I cannot promote either of you.你们两个我都不能提拔。No flower in his garden is red.他花园的花都不是红的。2.all 和every从意义上十分相近，都用来泛指人或物，然而两者各自与名词搭配的类别不同，every只能与单数可数名词连用。如：All Mondays are horrible.(= Every Monday is horrible. )all后可以跟the或this, my等限定词，而every却不行。例如：All the boys of this class are able to run faster than their teacher.试比较：She was here all day.她在这里呆了一整天。She was here every day. 她天天都在这里。3.every和each同属中位限定词，都可与单数名词连用，且意义相近，表示每个，然而every和each并不完全一样，every强调整体概括，each则表示个别概念。例如：Each day is better than the one before.一天比一天好。Every player was in good form.每个运动员都处于最佳状态。如果不特别强调某一意义时，every和each可以互换。例如：We want every child to succeed.我们希望每个孩子都成功。Each child will find his own personal road to success.每个孩子将会找到他个人的成功之路。each可以指两个或两个以上的人或东西，every却不能指两个，只能指三个以上的数量。例如：Each sex has its own physical and psychological characteristics.男女各有其身体上和心理上的特点。（不能说every sex.)另外，如有其他限定词同时修饰中心词，each可作代词取each of的形式，而every则只能作限定词。例如：Each of my parents gave me presents for Christmas.过圣诞节时我父母每人都给我送了礼物。4.either 和neither 同属中位限定词，与名词连用时不能和其他限定词同用（如冠词，物主代词，或指示代词）。either 和neither都只修饰单数可数名词，动词也用单数。例如：Either day is OK.两天中哪一天都行。Neither car is exactly what I want.这两辆车都不是我想要的。There were trees and flowers on either side of the street.街两旁都有树和花。Either kind of school is quite suitable.两种学校都挺适合。either也可指两个都与both的意义相近，但both后接复数名词,either则只接单数名词，而且both还可与其他限定词搭配。例如：Both (of) my children have been to America.另外，当either, neither与其他限定词连用时，则使用either of, neither of结构。例如：Either of the girls is quite capable of the work.两位女孩都能胜任这项工作。Neither of his cats has been fed.他的两只猫都还没喂。注意：此时动词用单数，不能用复数。但在否定句中却常用复数，neither of后单复数动词都可以，只是复数常用在非正式文体中。例如：I dont think either of the girls are capable of the work.我认为这两个女孩都不能胜任这项工作。Neither of your two answers is correct.你的两个回答都不正确。-自己整理either,neither 为一组，either 放于句尾，表示两者中选择一者，neither 一般与nor 搭配，表示两者都不。both 和all为一组，both 表示两者都而all表示两者以上的都。every和each 为一组，兴趣个例子来区别吧everyone 与 eachone.everyone 一般对象强调整体，比如教师上课时说Good morning everyone.对象是大家，而eac
