Question

问几个关于英语的问题

Answer 1

一。both:两个都(用于肯定) both只能与复数可数名词搭配，从意义上讲both指两者，
both用于否定时表示部分否定。 如：Both (of them) are not my brothers.他们两个之中，只有一个是我的兄弟。

二。each:每个(表个体)
Every:每个(表全体)

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

三。neither:两个都不(用于否定)
either:1).或者(用于选择)常与or 连用
2).也(表相同)(用于否定)

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 don’t 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。

四。最后举例：
1.Both the students are girls.(这个学生都是女生)
2.Each student has a pen.（每位同学都有一支笔）
3.Neither the student is from London.（没有学生来自伦敦）
4.Either he or she has a pen.注：has是被she 限定的，意思就是说，动词的形式与or 后面的主语一致。（他或她都没有笔）
例如，Either he or I have a pen.= He doesn't have a pen,I doesn't have,either.
