10、程度更深”。记住以下三个词组：further study（进修）further education（继续教育） further information （进一步的信息）elder仅用于同辈之间的排行，如: elder sister（姐姐） elder brother （哥哥）less作为“更少”仅用来修饰不可数名词，修饰可数名词表示“更少”要用fewer。第二章 形容词副词比较级较难考点少数单音节词前面加 more, most 构成比较级和最高级，这类形容词一般为表语形容词和由过去分词变成的形容词 afraid -more afraid, most afraid tired - more ti
11、red , most tired fond - more fond , most fond glad -more glad , most glad bored - more bored , most bored pleased- more pleased , most pleased下列形容词和副词的比较级和最高级有两种形式，即：既可加-er/-est也可加more/moststrict, often, friendly, clever下列形容词和副词没有比较级和最高（即表示“最高程度”或“绝对状态”的形容词和副词没有比较级和最高级）如：empty, wrong, perfect, uniqu
12、e, extreme, excellent, favourite, true, right, correct, extremely . 比较应在同类事物之间进行。误：Your English is better than me.正：Your English is better than mine.比较级前可以有一个表示程度的状语，最常见的三大修饰词是：a little, much, even。以下单词也可用来修饰：any, far, still, a lot, yet, rather。My sister is a little taller than me.Their house is muc
13、h larger than ours.另外，名词短语也可修饰比较级，说明程度。Im three years older than he.very, quite, too不可修饰比较级。 避免重复使用比较级。He is more kinder to small animals than I.He is much kinder to small animals than I.He is more cleverer than his brother.He is cleverer than his brother.比较要符合逻辑，在同一范围内比较时，避免将主语含在比较对象中，这时需使用other来排除
14、自身。China is larger that any country in Asia.China is larger than any other country in Asia.John studies harder than any student in his class.John studies harder than any other student in his class.John studies harder than any of the other students in his class.John studies harder than anyone else in
15、 his class.比较要遵循前后一致的原则，注意前后呼应。The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out. 序数词通常只修饰最高级。Africa is the second largest continent.The Yellow River is the second longest river in China.This is the third most popular song of Michael Jackson.为
16、避免重复，我们通常用that, those, one, ones代替前面出现的名词。that代替可数名词单数和不可数名词，those代替可数名词复数。one既可指人又可指物，只能代替可数名词。The weather in China is different from that in America.The book on the table is more interesting than that（或the one）on the desk.A box made of steel is stronger than one made of wood.In winter, the weather
17、 of Beijing is colder than it of Shanghai.In winter, the weather of Beijing is colder than that of Shanghai.“否定词 + 比较级”相当于最高级。-Wait until we get a satisfactory reply, will you?-I couldnt agree more. The idea sounds great to me.Nothing is so easy as this. =Nothing is easier than this. =This is the ea
18、siest thing.比较级前一般不加冠词。但表示两者中较突出者，且比较级后又有名词或出现了of the two，这时比较级前一定要加the。He is the taller of the two.Of the two jobs，he chose the harder.Which is the younger one, Lily or Lucy?试比较：Which is larger, Canada or Australia?Which is the larger country, Canada or Australia?She is taller than her two sisters.
19、She is the taller of the two sisters.不含than 的比较级前可加不定冠词修饰，构成“a/an+比较级+单数可数名词”表示“一个更的人/物”。Why dont you use a sharper knife? 你为什么不用一把更锋利的刀呢？比较级than 后应用人称代词的主格，但非正式语体中常用宾格。He is taller than I/me.为避免重复，比较级中同样的动词用助动词do, does, did替代。I spend less time doing homework than John does.She tells more funny joke
20、s than we do.以下内容不是初中教学的重点，仅供拓展之用。形容词most前面没有the，不表示最高级的含义，只表示“非常”。It is a most important problem.=It is a very important problem.倍数表达法 A is three（four, etc.）times the size（height, length etc.）of B.The new building is four times the size（the height）of the old one.这座新楼是那座旧楼的四倍大（高）/这座新楼比那座旧楼大（高）三倍。A i
21、s three（four, etc.）times as big（high, long, etc.）as B.Asia is four times as large as Europe. 亚洲是欧洲的四倍大/亚洲比欧洲大三倍。A is three （four, etc.）times bigger（higher, longer, etc.）than B.Your school is three times bigger than ours.你们的学校比我们的学校大三倍。用times表倍数通常用于三倍以上，两倍可以用twice或double. 第三章 形容词副词比较级最高级重点句型归纳句型一：形容词
22、或副词比较级+than注意事项：该句型为比较级的最基本句型。只要看到than，即可确定前面使用比较级。He is taller than I am.The boy does his homework more carefully than the girl.句型二：less + 形容词的原级 + than该句型表示“不如、不及”，特别需要注意的是，less本身就是little的比较级，后面必须跟形容词的原级，否定就造成了比较级的重复使用。This computer is less expensive than that one.句型三：as +形容词或副词的原级+ as该句型表示对比的两者程度
23、相当，as之间必须跟形容词或副词的原级，决不能使用比较级。此外，还要确定使用形容词还是副词。确定的依据就是根据第一个as前的动词，如果是系动词（如be，感官动词look, sound, smell, taste, feel等），那么就用形容词的原级，如果前面的动词是一般的实义动词，那么就必须用副词的原级修饰动词。This lesson is as easy as that one.Lucy talks with old people as politely as her sister.asas之间也可以跟名词，句型如下： as +形容词+ a/an +单数名词+as He is as kind
24、 a person as his father. 他和他爸爸一样都是善良的人。 as + many/much+不可数名词/可数名词复数+as I can carry as much paper as you can. 你能搬多少纸，我也能。 I have as many books as you do. 我的书和你的一样多。 Well give you as much help as we can. 我们将尽我们所能给你帮助。 其它几个关于asas的句型： as as one can：尽其所能 He began to run as fast as he could. as as possible：尽可能Please helpusas quickly as possible. as soon as一就 He will call me as soon as he comes here.句型四：not as/so +形容词或副词的原级+ as该句型表示“前者不如后者”，往往可以与句型一和句型二替换。第一个as可以换为so。This classroom is not as bright as yours.I cannot run as fast as you.句型五：the +形容词或副词最高级+
