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：

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。)

7、疑问代词：用来提出问题的代词称为疑问代词。
1、who、whom、whose、what、which、whoever、whatever、whichever主要用于特殊疑问句中,一般放在句首。口语中也常用who代替whom作宾语,但在介词后则只能用whom。如：
Who(m) did you invite to your birthday party?(你都邀请了谁参加你的生日聚会的？) / What does she want to be when she grows up?(她长大了想干什么？)
2、who 和whom只能独立使用,其中who可以作句子的主语、表语或动词的宾语,whom只能作谓语动词的宾语；而what、which、whose等既可以独立使用作主语、表语和宾语,也可以与名词构成疑问短语。如： Who is that man?(那男的是谁？) / What colour are their hats?(他们的帽子是什么颜色？) / Which car was made in Germany?(哪辆车是德国造的？)(被动句)
注意这个提问：The man in the car is my father.(车里的男人是我父亲)
→Which man is your father?(哪个男人是你的父亲？)
3、which除了可以询问指代的情况之外,还可以针对说明人物的时间、地点、岁数、颜色、大小、状况等进行提问。如：People there live a very sad life.(那里的人生活凄惨) →Which people live a sad life? (哪些人生活凄惨？)/ --Which hotel have you booked for your holiday?(为了度假你预订了哪家旅馆？)—The biggest one in Haikou.(海口最大的那家旅馆)
4、疑问代词不分单复数,视它所替代的人或事物决定单复数,但是通常用单数；如果修饰名词,则以名词的单复数为准。如：Who is (are) in that playhouse?(谁在游戏房里？) / What is that? (那是什么？)/ What are those? (那些是什么？) / What colours do they have?(它们有哪些颜色？)
