【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 trees 6、 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）

A、一般情况下，在单数名词的后面加-s构成。如：game-games，boy-boys等。 B、以s、x、sh、ch结尾的单数名词变复数，在词尾加-es构成。如：box-boxes，bus-buses，peach-peaches，dish-dishes。 C、以o结尾，表示有生命的事物的单数名词变复数加-es；表示没有生命的事物的单数名词变复数加-s。如：potato-potatoes，tomato-tomatoes，photo-photos，piano-pianos等。 D、以辅音字母加y结尾的单数名词变复数，将y改成i后再加-es。如：factory-factories，story-stories，family-families。 E、以f或fe结尾的单数名词变复数，将f或fe改成v，然后再加-es。如：leaf-leaves，life-lives，knife-knives等。 F、名词单数变复数，除了有规则可循的变化之外，还有一部分的变化是不规则的，我们将这部分名词的变化叫做不规则变化。这些词有：goose-geese，foot-feet，tooth-teech，man-men，woman-women，mouse-mice，sheep-sheep，deer-deer，fish-fish，child-children，ox-oxen 4.不可数名词量的表示 需给这些词计量，我们于是采用这种方法： 如：a cup of tea，a box of milk，a piece of paper等。 如果为了表示多个的概念，我们就将表示这些东西的单位变成复数即

英语名词单数变复数的规则 一、绝大多数的可数名词的复数形式，是在该词末尾加上后辍-s。 读音变化：结尾是清辅音读[s]，结尾是浊辅音或元音读[z]。 例：friend→friends; cat→cats; style→styles; sport→sports; piece→pieces 二、凡是以s、z、x、ch、sh结尾的词，在该词末尾加上后辍-es构成复数。 读音变化：统一加读[iz]。 例：bus→buses; quiz→quizzes; fox→foxes; match→matches; flash→flashes 三、以辅音字母+y结尾的名词，将y改变为i，再加-es。 读音变化：加读[z]。 例：candy→candies; daisy→daisies; fairy→fairies; lady→ladies; story→stories 四、以-o结尾的名词，如果不是外来词或缩写，就加-es，否则加-s构成复数。 读音变化：加读[z]。 例：tomato→tomatoes; potato→potatoes; torpedo→torpedoes; bingo→bingoes 反例：silo→silos; piano→pianos（外来词）; photo→photos; macro→macros（缩写词） 五、以-f或-fe结尾的名词，多为将-f或-fe改变为-ves，但有例外。 读音变化：尾音[f]改读[vz]。 例：knife→knives; life→lives; leaf→leaves; staff→staves; scarf→scarves 反例：roof→roofs 六、以-us结尾的名词（多为外来词），通常将-us改变为-i构成复数。 读音变化：尾音[Es]改读[ai]，其中[kEs]要改读为[sai]，[gEs]要改读为[dVai]。 例：fungus→fungi; abacus→abaci; focus→foci; cactus→cacti; cestus→cesti 七、以-is结尾的名词，通常将-is改变为-es。 读音变化：尾音[is]改读[i:z]。 例：axis→axes; basis→bases; naris→nares; hypothesis→hypotheses; restis→restes 八、以-ix结尾的名词，通常将-ix改变为-ices，但有例外。 读音变化：尾音[iks]改读[isi:z]。 例：matrix→matrices; directrix→directrices; calix→calices; appendix→appendices 反例：affix →affixes 九、以-um结尾的名词，将-um改变为-a。 读音变化：去掉鼻尾音。 例：forum→fora; stadium→stadia; aquarium→aquaria; datum→data; vacuum→vacua 十、以-a结尾的名词，在该词末尾加上后辍-e。 读音变化：尾音[E]改读[i:]。 例：larva→larvae; formula→formulae; ala→alae; media→mediae; hydra→hydrae
be动词的一般现在时有三种形式，即：am, is, are。 1. 如果主语是第一人称I（我）时，be动词用am。 如：I am a student. 我是一名学生。 I am 还可缩写成I'm。如： I'm David. 我是大卫。 2. 如果主语是you （你，你们）, they （他们，它们，她们）或名词复数（两个以上的人或物）时，be动词必须用are。 如：Are you twelve? 你是十二岁吗？ Tom and Lily are good friends. 汤姆和莉莉是好朋友。 They are at school. 他们在学校。 are与主语还可缩写。如：We are= We're，They are =They're, You are = You're。而are与not 可缩写成aren't。 如：They aren't students. 他们不是学生。但是am与not不能缩写。 3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。 如:My mother is a teacher. 我的妈妈是一名老师。 He is a student. 他是一名学生。 is也可与主语缩写,如: He is = He's, My mother is = My mother's等。但是This is不可缩写。而is 与not可缩写成isn't。 如:This isn't a book. 这不是一本书。 根据以上叙述我们可以把动词的用法以口诀的形式表述出来： 我（I）是am, 你（you）是are, 剩下is留给她（she）, 他（he）, 它（it）, 两个以上都用are。 英语的be 动词是个用法比较复杂的动词。复杂的原因有两点： 1、除了原形的be 之外，对于不同人称代词以及单数名词和复数名词，be 会有各种变化形式和缩写形式。概括一下有七种形式：be, am, is, are, was, were, been, being。它们与人称代词和名词单、复数的搭配关系是： 现在时I am, you are, he/she/it/ is, we/you/they are；名词单数、不可数名词用is，复数用are。 缩略式I'm, you're, he's, we're, you're, they're 否定缩略式I'm not, isn't, aren't 过去时I was, you were, he/she/it/ was, we/you/they were；名词单数、不可数名词用was，复数用were。否定缩略式wasn't, weren't 过去分词been 现在分词being 2、在句子中，be有两种主要作用：一是作为系动词(The Linking Verb)，本身可以作用谓语动词；二是做为助动词(The Auxiliary Verb)，与谓语动词一起构成各种时态和被动语态等。
语法学习一直是一个令同学们头疼的事情,老师讲得多了，同学们不愿听，讲得少了，又听不懂，不会用。因此在清华少儿英语邯郸市服务中心的每期的学习报中,Sophia将带领 同学们走进有趣的语法顺口溜的课堂,以保持同学们的学习兴趣和学习热情，从此学习语将不再枯燥,收到良好的学习效果. 名词单数变复数，几种规则要记住： (一) 规则变化 名词单数变复数，直接加 -s 占多数； s, x, z, ch, sh 来结尾，直接加上 -es；词尾是 f 或 fe，加 -s 之前先变 ve； 辅母 + y 在词尾，把 y 变 i 再加 -es；词尾字母若是 o，常用三个已足够， 要加 -es 请记好，hero, tomato, potat o。 (二) 不规则变化 男人女人 a 变 e，鹅足牙 oo 变 ee； 老鼠虱婆也好记，ous 变 ic； 孩子加上 ren，鱼鹿绵羊不用变。
This---these(这些) that -- thos e(那些) 【解说】 1. 英语名词有单数和复数的区别，单数表示“一”，复数表示“多于一。”名词由单 数变复数，多数是规则的变，直接加 -s，例如：book → books, girl → girls。但以 -s, -z, -x, -ch, -sh 结尾的名词，变成复数时加 -es, 例如：bus → buses, buzz → buzzes, box → boxes, watch → watches, brush → brushes 2. -f(e) 结尾的名词单数变复数歌诀：①树叶半数自已黄，妻子拿刀去割粮，架后窜出一只狼，就像强盗逃命忙。②妻子持刀去宰狼，小偷吓得发了慌，躲在架后保己命，半片树叶遮目光。例如：leaf (树叶，叶子)，half (一半)，self (自已)，wife (妻子)，knife (刀子)，shelf (架子)，wolf (狼), thief (窃贼，强盗) 和 life (生命)，这些名词变成复数时，都要改 -f (e) 为 v，再加 -es。 3. -f 结尾的名词直接加 -s 变复数歌诀：海湾边、屋顶上，首领奴仆两相望；谁说他们无信仰，证据写在手帕上。例如：gulf, roof, chief, serf, b
