小学四年级英语语法智趣外语学校四年级语法大全 第一章 名词 名词的概念 在生活中,我们会接触到各种各样的人和事物,用来表示这些人或事物名称的词就是名词。 一、名词的数 名词的数指名词的单数和复数形式。可数名词表示一个时用单数,两个以上时用复数;不可数名词表示量时,通常用数词+单位+of+物质名词的形式,如 a piece of bread (一片面包), 变为复数时,只须将单位名词变为复数, 如:two pieces of bread(两片面包)。 *名词复数的构成法则 1. 一般情况下在词尾加 s. 词尾读音 shop - shops (商店) 在清辅音后读 s bag - bags (书包) 在浊辅音后读 z window - windows (窗户) 在元音后读 z 2. 以 s, x, sh, ch 结尾的单词在词尾加es。 class - classes (班级) 词尾读音 iz box - boxes (盒子) match - matches (比赛) brush - brushes (刷子) 3. 以辅音字母 +y 结尾的词, 变y为 i 加es. story - stories (故事) 词尾读音 iz 4. 以元音字母 +y 结尾的词,在词尾直接加 s key - keys 词尾读音 z monkey - monkeys 5.以 o 结尾的名词, 复数一般在词尾加s, 但个别加 es tomato - tomatoes (西红柿) 词尾读音 z potato - potatoes (土豆) zoo - zoos (动物园) photo - photos (照片) *口诀: 黑人(Negro)英雄(hero),左手拿着西红柿(tomato),右手拿着破土豆(potato), 头顶一个大芒果。 6. 以 f或 fe 结尾的词,多数变f或 fe 为 ves. leaf - leaves (树叶) 词尾读音 vz knife - knives ( 小刀) *口诀: 妻子持刀去宰狼,小偷吓得发了慌,躲在架下保己命,半(half)片树叶遮目光。 *口诀: 长颈鹿(giraffe)站在屋檐(roof)下,左手拿着手绢(handkerchief),右手拿着高尔夫球(golf)。 例: roof - roofs ( 屋顶) 7. 不规则名词复数的变化 man - men (男人) tooth -teeth (牙齿) child - children (儿童) mouse - mice(老鼠) foot - feet (脚) woman - women (女人) 8. 名词单复数形式一样 sheep - sheep (绵羊) deer - deer English - English Chinese - Chinese *口诀: 男人,女人a变e; 鹅,足,牙齿oo变ee; 其实老鼠也好记ous变ic; 孩子加上ren,鱼鹿绵羊不用记。 二、名词所有格的构成法 1. 主要是在词尾加 s 构成。如: This is Toms desk . 这是汤姆的书桌。 That is Mikes book. 那是迈克的书。 2. 如果原名词已经有复数词尾s ,则仅加一个 . 如: the teachers reading room 教师阅览室 the pupils pencil-boxes 学生们的文具盒 3. 如果原词是复数形式,但不是以s 结尾, 变为所有格形式需在后面加上 s 。如: the childrens palace 少年宫 mens room 男厕所 1 *名词所有格口诀: 名词所有格,s前面加一撇,复数s放在尾,后加一撇就完结,两人共有算一个,后面只加一个撇。 名词练习题 一、写出下列名词的复数形式 puter _ 2.apple _ 3.city _ 4.house _ 5.sheep _ 6.watch _ 7.tomato _ 8.child _ 9.tooth _ 10.foot_ 11.wife _12.potato _ 13.play _ 14.day _ 15.glass _ 16.radio _ 17.zoo _ 18. life _19. story _ 20.leaf _ 21. baby _ 22.dress _ 23.butterfly _24. deer _25.class _ 26.brush _ 27.key _28.
