each用法

Answer 1

Each的用法
一、each作“各自的”,“每个的”解,作形容词用：
1.There are many trees on each side of the river.河流两岸许多树.
2.Each element has some special properties.每种元素都有些特殊性质.
二、作“各子”、“每个”讲,作代词用：
1.Each has his advantages.各人都有其优点.
2.He gave each of us a tool.他给我们每人一件工具.
三、作“各子地”讲,作副词用：
1.Give them two books each.(=Give each of them two books.)给他们每个人两本书.
2.The students have ten books each.(=Each of the students has ten books.)这些学生每人有十本书.
3.Different kinds of waves have each the same three characteristics:amplitude,frequency and length.不同的波（各）都有三个相同的特性：幅度、频率和波长.
四、注意each作同位语的用法：
1.They each put forward a proposal.他们每人提出一条建议.
2.The workers are each of them hard-working.这些工人个个勤奋劳动.
五、each other作“互相”、“彼此”
1.We help each other.我们互相帮助.
2.They speak English to each other.他们彼此讲英语.
3.We often compare notes with each other on our work and study.我们经常就工作和学习方面互相交换意见.
六、each和every词义辨异：
Ⅰ.every只能作形容词,只有在与名词连用或构成复合词（如everybody每个人）时,才能作主语或宾语等,而each还可以作代词,直接作主语或宾语（见本文二各例句）.
Ⅱ.every虽指每个,而概括全体,而each只是指“每个”,却以“各……”为主.例如：
1.I know every member of the class.全班的人我都认识.（着重全体,即虽指每个,而概括全体.）
2.I know each member of the class.这个班每个人我都认识.（“个别”意义较重.）
3.We must correct every single error.我们必须改正所有错误.（着重全体.）
4.They each have a tool.他们每人有一件工具.（“个别”意义较重.）
5.Hydrogen and sodium each have one electron in the outer layer.Each has a combining power of one.They each have one electron to lend to anther atom.氢和钠在外层各有一个电子.它们的化合价都是1.它们各有一个电子可借给其他原子.（句中第一、三个each作同位语,第二个each为代词作主语.这三个each都是“个别”意义较重.句中第二个one是通过of引出的同位语.）
