小学英语基本语法 第一讲 名词 知识要点 一、名词的数 在英语中，名词按其所表示的事物的性质可分为可数名词和不可数名词。可数名词有单数和复数两种形式。单数名词表示一个可数事物。复数名词表示两个或两个以上的可数事物。可数名词可分为单数和复数两种形式：表示一个人或事物的名词用单数形式，在使用时，前面一般加不定冠词a或an，表示两个或两个以上的人或事物的名词用复数形式,一般是在词干后附加词尾s 或es,如：bags ,boxes.名词单数变复数具体规则如下： 1).规则变化 ①一般在名词后加s.如boy→boys, pen→pens等。 ②以s, x, sh, ch结尾的，在后面加es.如class→classes,但stomach的复数为stomachs. ③“以辅音字母+y”结尾的，y变为i，然后再加es.如baby→babies. ④以f或fe结尾的名词把f或fe改为v, 再加es. 如knife, half, leaf, wolf等。 ⑤以o结尾的名词，除tomato, potato等少数在后面加es外，一般是在后面直接加s.如kilo→kilos, photo→photos, zoo→zoos, radio→radios, piano→pianos, video→videos. 2).不规则变化 1 man→men, woman→women, foot→feet, tooth→teeth,，child-children，mouse→mice 2 单复数形式相同如：sheep→sheep, deer→deer, Japanese→Japanese, Chinese→Chinese等。 3 有些名词形式上是单数，实为复数意义，通常被称为复数名词，如：people, police等。 4 由-man和-woman构成的合成词如：policeman→policemen, Englishman→Englishmen，Englishwoman-Englishwomen但German不是合成词，故复数形式为Germans.另外被man 或woman 修饰的名词变复数时，两个名词都要变。例：a man doctor →two men doctors a woman teacher→some women teachers 但: apple tree→apple trees 5 有些名词只有复数形式，如：clothes, trousers, glasses, chopsticks等。 ⑥数词+名词作定语时， 常采用数词+单数名词形式，如a two-week holiday, an 8-year old girl.另一种常见的形式有five minutes’ walk, two days’ leave等。 3）不可数名词没有单复数形式，要表示不可数名词的数量，可用以下两种方法。 ①用much, a little, a lot of /lots of some, any等修饰不可数名词。如： The rich man has a lot of money. ②可用表单位的词修饰不可数名词， 如：a piece of paper, two pieces of paper, a bottle of orange, a glass of milk, three bags of rice。 二、名词的格 1）表示有生命的东西（人或动物）的名词所有格一般在名词后加’s .如：my father’s study以s或es结尾的复数名词的所有格只在名词后加’ 如： the teachers’ reading room 教师阅览室;不以s结尾的复数名词的所有格要加’s.如：the women’s shoes 女式鞋子。如果一样东西为两人共有，则只在后一个名词的后面加’s。如果不是共有的，则两个名词之后都要加’s .如：Jane and Helen’s room 珍妮和海伦的房间(共有)Bill’s and Tom’s radios 比尔的收音机和汤姆的收音机（不共有） 2）表示无生命的东西，一般用 of+名词的结构。如：a map of China 　练习： I.写出下列名词的复数形式。 1.watch ____________ 11.strawberry _______________ 2.child _____________ 12.thief ____________________ 3. photo ____________ 13.girl student_______________ 4.diary ____________ 14.man doctor_______________ 5.day______________ 15.woman nurse_____________ 6.foot______________ 16.pear tree_________________ 7.book____________ 17. peach____________________ 8.dress ____________ 18. box______________________ 9.tooth____________ 19. baby____________________ 10. deer___________ 20.

My brother is the taller of the two. ③“比较级+and+比较级”表示“越来越……”。He is getting taller and taller. ④“the+比较级，the+比较级”表示“越…,越…,”。The more careful you are，the fewer mistakes you’ll make 5).最高级常用句型结构 ①“主语+be+ the+形容词最高级+单数名词+in/of短语”表示“……是……中最……的”。 如，Tom is the tallest in his class./of all the students. ②“主语+be+ one of the+形容词最高级+复数名词+in/of短语”表示“…是……中最……之一”。 如，Beijing is one of the largest cities in China. ③序数词+最高级 Hainan Island is the second largest island in China. 练习： I.写出所给词的反义词。 1.young________ 6.better___________ 2. white________ 7. longer__________ 3. big__________ 8. thinner_________ 4. left_________ 9. far_____________ 5.fast_________ 10. light__________ II. 用所给词的正确形式填空。 1.
