every和each用法：
every是形容词,只能作定语修饰单数名词,意思是“每一个”,表示整体概念;
each是形容词、代词,可用作主语、宾语、定语等,意思是“每个”或者“各个”,表示单个概念;each可以放在名词前,可以后跟of短语,与动词同时出现时要放在“be动词、助动词、情态动词”之后或者行为动词之前
every和each都用作单数理解,但是下文中既可以用单数的代词(如he/him/his)也可以用复数的代词(如they/them/their)替代。如：Every one of the students in his class studies very hard.(他班上每个学生学习都很用功) / They are very busy. Each of them has something to do.(他们很忙,人人都有事干)
(5)either和neither的用法：
either意思是“两个中间的任何一个”;neither是either的否定形式,意思是“两个都不”。
neither和either在句子中可作主语、宾语和定语等,都用作单数。如：I don’t care much for what to drink. Either of the two will do. (我不介意喝些什么,两个之中随便哪个都行) / --Will you go there by bus or by car? –Neither. I will go there by train.(你坐公车去还是坐轿车去?一个都不坐,我坐火车去。)
(6)other、the other和another的用法：
other意思是“另一”、“另一些”,有复数形式。在句子中可作主语、宾语和定语。another意思是“另外”、“又一个”,表示增加,在句中可作宾语和定语。如：

another(另外的,再一,又一)与the other(另外的一个) 主要从数量上区分,只有两个时用the other,在原先基础上增加用another。如： This is one of your socks. Where is the other one?(这是你的一只袜子,还有一只呢?) / I have eaten 4 cakes, but I still want another.(我已经吃了4块蛋糕,但是我还要以块。)
others与the others的主要区别：others指“剩余的人/物”(指大部分);the others指“其余的人/物”,(指全部)。如：A few students are playing soccer while others are watching them.(有几个学生在踢足球,其他一些人在观看) / Two of the ten boys are standing and the others are sitting round them.(十个男孩中有两个站着,其他人都围着他们坐着。)

many和much一般用于否定句,肯定句中通常用a lot of 或者lots of; many / much用于肯定句时可以在前面加上so、very或too.如： There are a lot of people on the playground.(操场上有许多的人)/ They haven’t got much work to do.(他们没有多少事情可做) / There are too many people in the room.(房间里人太多了。)
