23、at-fatter，hot-hotter等。（5）多音节和部分双音节的形容词，可不是在末尾变化，而是在前面加more。如：careful-more careful，athletic-more athletic等。2. 不规则变化good /well-better bad /badly-worse many /much-more few /little-less二形容词比较级的用法在描述单个的某人或某物所具有的特征时，需要用形容词原级形式，当把两者进行比较时，就用比较级，常见的表示这类用法的句型有：1.“A+be+比较级+than+B”表示“A在某方面超过B”。如：This book is de

24、arer than that one. 这本书比那本书贵2.“Which /Who(se)+be+比较级, A or B?”意思是“A和B，哪个更.”。如：Which is bigger, the sun or the earth? 太阳和地球，哪个更大？Whose bag is heavier, yours or mine? 谁的包重些，你的还是我的？3.“A+be+the+比较级+of the two()”意思是“A是两者中较.的一个。”这时前面一定要加the，表示特指。如：Lily is the taller of the twins. 莉莉是双胞胎中个子较高的那个。三常与比较级连用的词

25、1. 前面可以加上a little，a lot，much，even，still等程度副词作修饰语。如：She is much more careful than her brother. 她比她哥哥细心多了。2. 前面还可以加表示数量、倍数的修饰语。如：My brother is two years older than I. 我哥哥比我大两岁。This room is twice bigger than that one. 这个房间比那个房间大两倍。四使用比较级应注意的问题1. 避免比较对象的不相同。如：误My schoolbag is newer than you.正My schoolba

26、g is newer than _2. 避免与自身相比。如：误Shanghai is bigger than all the cities in China.正Shanghai is bigger than all the _ cities in China.例：Shanghai is bigger than _in Jiangsu.A. any other cities B. all the other cities C. any cities D. other cities一用所给形容词的正确形式填空1.

B三. 1. older than, younger than 2. shorter than 3. as big as可数名词与不可数名词名词分为可数名词和不可数名词两大类。大多数名词为可数名词，有单复数之分，而不可数名词没有复数形式。1.可数名词变复数分为规则变化和不规则变化两种：(1)规则变化1)一般名词变复数时，直接加-s。如：book-books pen-pens hat-hats2)以字母-s，-x，-sh，-ch结尾的名词，在词尾加-es。如：bus-buses glass-glasses class-cla

31、sses box-boxes fox-foxes watch-watches brush-brushes dish-dishes wish-wishes3)以-f，-fe结尾的，把f，fe变为v，再加-es。如：leaf-leaves half-halves self-selves wife-wives knife-knives wolf-wolves shelf-shelves thief-thieves life-lives 可把以上九个以-f，-fe结尾的词串成这样的一句口诀记忆：树叶(leaf)半数(half)自己(self)黄，妻子(wife)拿刀(knife)去杀狼(wolf)，架

32、(shelf)后小偷(thief)逃命(life)忙。注意：有些词虽然也是以-f结尾，但复数形式却是直接加-s。如：roof(屋顶)-roofs belief(信仰)-beliefs proof(证据)-proofs handkerchief(手帕)-handkerchiefs4)以“辅音字母+-y”结尾的，先变y为i，再加-es。如：family-families lady-ladies city-cities5)以-o结尾的，有时加-es，有时加-s加-es的可串成口诀记忆： 黑人(Negro)英雄(hero)爱吃西红柿(tomato)和土豆(potato)。注意：千克的复数形式为kilo

33、s。如：I weight 52 kilos. 我的体重是52公斤。(2)不规则变化有些名词变复数时属于不规则变化，这种变化是通过改变单词中的某个字母或在词尾加后缀构成的。1)该a为e型：man-men woman-women Englishman-Englishmen Englishwoman-Englishwomen Frenchman-Frenchmen Frenchwoman-Frenchwomen policeman-policemen policewoman-policewomen2)该oo为ee型：foot-feet tooth-teeth goose-geese3)在词尾加-re

34、n。如：child-children 4)其他特殊变化。如：mouse-mice2.不可数名词及其量的表示法：(1)不可数名词包括：物质名称：食物：bread meat rice cheese fish beef 饮料：milk water cola coffee wine tea 自然物质：air soil sand wood抽象名词：情感：love peace friendship joy happiness 概念：exercise knowledge energy population 学科：math geography physics chemistry(2)不可数名词的量的表示法：如

35、果要表达出不可数名词具体的数量，可以通过“计量词+of+不可数名词”来表示。若想表达量的复数概念，只需把计量词变为复数形式即可。如：a piece of paper 一张纸 ten pieces of paper 十张纸 a cup of coffee 一杯咖啡 two cups of coffee 两杯咖啡a piece of news 一条消息 two pieces of news 两条消息 a drop of ink 一滴墨水 three drops of ink三滴墨水a bottle of milk 一瓶牛奶 five bottles of milk 五瓶牛奶 a bag of ri

36、ce 一袋大米 twenty bags of rice 二十袋大米(3)可数名词与不可数名词的区别及其应用：1)可数名词单数可用修饰，复数可用基数词及some，any，few，a few，many，a lot of等来修饰。不可数名词不能直接用数词修饰，需用“基数词+计量词+of”结构，也可用some，any，little，a little，much a lot of来修饰。2)用how many询问可数名词数量的多少。用how much询问不可数名词数量的多少。3)单个单数名词作主语，谓语动词用单数；多个单数名词或复数名词作主语，谓语动词要用复数。不可数名词作主语，谓语动词用单数。但当其前有

37、“基数词+计量词+of”时，谓语动词依计量词而定。特别提醒：有些名词既是可数名词，又是不可数名词，但两种情况下的含义是不同的。如fish作可数名词表示“不同种类的鱼”，作不可数名词表示“鱼，鱼肉”。一 词组翻译 一个洋葱_ 六个西红柿_ 两杯咖啡_ 三茶匙调料_ 十瓶酸奶_ 四片面包_ 六位女医生_ 五名男学生_二 单项填空1.
