【发卷日期】2013年______月_______日 【学生姓名】__________________________一、如何把“单数句”变成“复数句”：1、 “人称代词/物主代词/反身代词的单数形式”变成相应的“人称代词/物主代词/反身代词的复数形式”。
也就是说：2、 be 动词变成相应的复数形式：am/is 变为___________，was 变为___________。
3、 不定冠词a/an 要________________________（去掉/保留），固定搭配除外。
例如：He is a boy.→They are boys.4、 指示代词：this 变为__________________，that 变为__________________。
例如：This is a book.→These are books.5、 man 和woman 作定语修饰可数名词时，要在"数"上与被修饰名词保持一致。
也就是说，当man 和woman 修饰可数名词．．．．时，在整个句子变成复数的情况下，它 们也变为复数形式：___________________________和___________________________。
例如：She is a woman teacher.→They are women teachers.【注意】当名词修饰名词表“性质”时，不作变化。
如：apple tree → apple trees6、 单数句变复数句时，句中的形容词、副词、定冠词、特殊疑问词、介词短语和感叹词等__________________________________________________（必须改变/保持不变）。
例如：Who is she? 她是谁？→ Who are they? 她们是谁？7、 有的英语单数句不可以变成复数句，必须根据题目的实际情况进行具体分析。
例如：My name is Kate. 我叫凯特。
Three plus two is five. 三加二等于五。
8、 可数名词的单数形式要变为_______________形式。
例如：It is a cat. → They are cats.book 书 →house 房子 →day 日子 → ruler 尺子 →bus 公共汽车 → waitress 女服务员 → dress 连衣裙 → glass 玻璃杯 → class 班 → box 盒子 → fox 狐狸 → dish 碟子 → brush 刷子 →watch 手表 →peach 桃子 → coach 教练 →【注意】有些单词例外，它们本身就以字母s 结尾，如：news 新闻（不可数名词）wife妻子→knife小刀→thief小偷→shelf架子→self自我→life生命→leaf树叶→wolf狼→candy糖果→country国家→family家庭→city城市→story故事→party舞会→library图书馆→factory工厂→baby婴儿→dictionary字典→【注意】有些单词例外：roof屋顶→roofs，safe保险箱→safes，chief长官→chiefsphoto照片→piano钢琴→studio工作室→radio收音机→zoo动物园→bamboos，kangaroo袋鼠→kangaroos（2）一般表示有生命含义的词，加es。
例如：hero英雄→tomato番茄→potato土豆→（3）有的既可加s，也可加es。
zero零→volcano火山→tobacco烟丝→tooth牙齿→businessman商人→foot脚→fireman消防员→goose鹅→policeman警察→man男人→postman邮递员→woman女人→child孩子→fish鱼→mouse老鼠→sheep绵羊→deer鹿→【注意】（1）与man和woman构成的合成词，两部分都要变成复数形式。
例如：男消防员（单数）man fireman →男消防员（复数）men firemen女医生（单数）woman doctor →女医生（复数）women doctors （2）但要与下列情况区分开来：男学生（单数）boy student →男学生（复数）boy students女学生（单数）girl student →女学生（复数）girl students8.集体名词：表示同一类别的人、动物或物件的集合体的名称，叫做集体名词。
（1）集体名词中有的是可数名词。
例如：family家庭，class班，team队，group小组，army军队，police警察（2）集体名词中有的是不可数名词，形式上都用单数形式。
例如：clothing衣服，furniture家具（3）如果表示整体概念时，作单数看待，谓语动词用单数。
例如：Our team needs money to play in another city.我们的球队需要资金去另一个城市打球。
（4）如果强调的是集体中的个体成员时，作复数看待，谓语动词用复数。
例如：My family are very well. 我的家人都很好。
9.合成名词：合成名词必须用连字符“-”把前后的单词连起来；无论连起来的词有多少个，只要有连字符连接，统统视为一个单词；合成词中的任何一个单词都不能变复数。
合成名词用作定语，常见的有两种形式：（1）数词-名词。
例如：一个7天的假期a ____________________________________________________ holiday 一台10小时的手术a ______________________________________________ operation （2）数词-名词-形容词。
例如：一位2米高的篮球运动员a _________________________________ basketball player 一栋85米高的大楼a ________________________________________________ building 【练习】将下列各单数句改成复数句：例：（单数句）I am a student. →（复数句）We are
