比较级
比较的用法:
①双方比较, 表示一方超过另一方时, 用“比较级+than”的结构表示。例如:This pen is better than that one. He is cleverer than his sister. 但注意这种表达法:She is the older of the two sisters.
②表示一方不及另一方时, 用“less+原级+than”的结构表示。例如:This park is less beautiful than that one.
③表示一方超过另一方的程度或数量时, 可在比较级前加表示程度的状语(如even, a lot, a bit, a little, still, much, far, yet, by far等)修饰。例如:He works even harder than before. Things are far worse than expected. 注意:英语比较级前若无even, still, yet等时, 译成汉语时可用“较”或“??一些”, 或不译出, 一般不用“更”。例如:She feels better than yesterday. 她比昨天好些了。Please come earlier tomorrow. 请明天早点来。注意:by far通常用于强调最高级。用于比较级时, 一般放在比较级的后面, 如放在前面, 应在中间加“the”。例如:He is taller by far than his brother. He is by far the taller of the two brothers.
④表示一方随另一方的程序而变化, 即表达“越??(就)越??”意义时, 用the+比较级(主语+谓语), the+比较级(主语+谓语)”的结构。例如:The harder he worked, the more progress he made. The more you listen to English, the easier it becomes.
⑤不与其它事物相比, 表示本身程度的改变, 即表达“越来越??”意义时, 用“比较级+and+比较级”的结构。例如:The weather is getting colder and colder. The city is becoming more and more beautiful.
⑥“no+比较级”与“not+比较级”结构含义不同。“no+比较级”表示两个人(事物)都含有与该形容词相反的属性;“not+比较级”表示两个事物都具有该形容词的属性, 只是在程度上前者不如后者。试比较:Tom is no taller than Jack. (=Tom is as short as Jack. ) Tom is not taller than Jack. (=Tom is not so tall as Jack.)
⑦某些以or结尾的形容词进行比较时, 用to代替than。(这些词有inferior, superior, junior, senior, prior等。) 例如:He is superior to Mr. Wang in mathematics.
⑧在比较从句中, 为了避免重复, 我们通常用that(those), one(ones)代替前面出现的名词。that指物, one既可指人, 也可指物。that可代替可数名词单数和不可数名词, 而one只能代替可数名词。例如:The book on the table is more
interesting than that on the desk. A box made of iron is stronger than the one made of wood.
⑨倍数表示法。假定两事物A和B对比, 比较中有A是B的几倍和A比B大(小)几倍两种情况:
(1)A是B的几倍可表示为:A is. times as+形容词(副词)原级+as
B. /A is. times the size(length/height/amount etc. ) of B. 例如:这座桥是旧桥的3倍长。
①This bridge is three times as long as the old one.
②This bridge is three times the length of the old one.
(2)A比B大(小)几倍或多(少)几倍可表示为:
A is. . . times+比较级+than
B. /A is. times + more(less)than B. 例如:这座桥比旧桥长3倍。This birdge is three times longer than that of the old one. =This bridge is four times as long as the old one. 再如:我厂今年的产量比去年多2倍。The output of our plant this year is twice larger than last year. =The output of our plant this year is three times the amount of last year. 用times表示倍数, 一般只限于表示包括基数在内三倍或三倍以上的数。表示两倍可以用twice或double。
最高级的用法:
①三者或三者以上相比, 表示最高程度时, 用“the+最高级”的结构表示。这种句式一般常有表示比较范围的介词短语。例如:Zhang Hua is the tallest of the three. He works(the)hardest in his class. This is the most brave nation in the world.
②最高级可被序数词以及much, by far, nearly, almost, by no means, not quite, not really, nothing like等词语所修饰。例如:This hat is by
far/much/nearly/almost/not nearly/by no means/not quite/nothing like the biggest. How much did the second most expensive hat cost.
③表示“最高程度”的形容词(如excellent, extreme, perfect, favourite等)没有最高级, 也不能用比较级。
④形容词最高级修饰作表语或介词宾语的名词、代词时, 被修饰的词往往省略。例如:He is the tallest(boy)in his class.
⑤作状语的副词最高级前可以不加定冠词。例如:Of all the boys he
came(the)earliest.
⑥下列比较级结构可用来表同一范畴内的最高级的含义:
1. 形/副比较级+ than+any other+单数可数名词
{ (any of) the other+复数名词
any others/the others
any of the+复数名词
2. 形/副比较级+than+anyone else/anything else
3. 形/副比较级+than+ever(before)
4. no+形/副比较级+分句than分句, 例如:
India produces more films than any other country in the world .
They make fun of me because I’m shorter than anyone else.
They make fun of me because I’m shorter than anyone else.
As a result, the number of people who travel by plane in China is larger than ever before.
Mary is no richer than
1.“as+adj/adv+as或not so(as)+adj/adv+as.”句型。该句型常用来描述两个比较对象的程度上的相似或不同(即平时说的“等级比较和不等级比较”)。例如：
My computer is not so(as) expensive as yours.我的电脑不如你的贵重。
2.“as many/few+可数名词复数+as”或“as much/little(少的)+不可数名词+as”。前者描述数目上的接近，后者描述量的相近。例如：
You may borrow as many books as you can.你能借多少书就借多少。
“Drink as much water as you can.” the doctor said to him.医生对他说到：“你要尽可能的多喝些水。”
3.“主语+比较级+than any other…”结构表示：主语所描述的事物比其他任何一个都……比较级形式表示最高级含义。例如：
Li Ming is much cleverer than any other student in their class.李明是他们班中最聪明的学生。
注意：若比较范围不同，than后应用“any+可数名词的复数形式+其他”。例如：
China is larger that any countries in Africa.中国比非洲上的任何国家都大。
4.诸如not, never之类的否定词与形容词或副词的比较级连用，表示最高级含义。意为：再没有比…更…的了。例如：
It is not a better idea.这是再好不过的一个办法了。
I have never heard such an interesting story.我从来没有听过比这更有趣的故事了。
5.“形容词+to”结构也可表示比较含义。例如：
This kind of car is superior in quality to that.这种汽车的质量比那一种好得多(superior to意为：优于；胜过。)
Li ping is three years senior to Liu Gang.李平比刘刚大三岁。(senior to意为：年长于；资格老于；地位高于。)
6.“no+比较级+than”结构表示对两个比较对象都进行否定(可由
neither…nor…结构来改写)。例如：
I’m no more foolish than you.我们俩都不傻。(相当于Neither I nor you is foolish.)
7.“not more+比较级+than”结构表示在程度上前者不如后者。例如：
This book is not more interesting than that one.这本书不如那本书有趣。(相当于The book is less interesting than that one.)
8.“形容词比较级+than+形容词”，意为：与其…倒不如…。例如：
Jack is much harder than clever.与其说杰克聪明，倒不如说他学习用功。
9.would rather…than, prefer…to…, prefer to do…rather than…这三个句型表示“宁愿…而不愿…；喜欢…胜过…；宁愿做…而不愿做…”含义。虽无比较级形式，但表示比较级含义。例如：
She would rather die than give in.她宁死不屈。
He preferred to go out rather than stay home.他宁愿出去也不愿呆在家里。
10.“The+比较级…，the+比较级…”。该结构意为“越…，越…”。例如：
The more difficult the questions are, the less likely he is able to answer them.问题越难，他回答出来的可能性就越小。
11.what有时也可以表示“比较”关系，说明两种事物的相同或相似性。what的该种用法常用于书面语，用来加强修辞效果，含有比喻含义，相当于as，意为“好比…；正如…；就像…一样”。what的该类用法共有3种情况：
(1)A is to B what C is to D
Twelve is two what twenty-four is to four.十二比二就等于二十四比四。
(2)what C is to D, A is to B
What food is to the body, a book is to the mind.书籍对于思想犹如食物对于身体。
(3)what C is to D, that A is to B
What the gun is to a soldier, that the pen is to a writer.作家的笔犹如战士的枪。
1．“A + be +形容词比较级 + than + B” 意思为“A比B更……”。 如：This tree is taller than that one. 这棵树比那棵树高。 注意： ① 在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。 ②在
比较级前面使用much，表示程度“强得多”。 如：A watermelon is much bigger than an apple. ③ very, quite一般只能修饰原级，不能修饰比较级。 2．“比较级 + and + 比较级”或“more and more +原级”表示“越来越……” 如：It becomes warmer and warmer when spring comes. 春天来了，天气变得越来越暖和了。 It is getting cooler and cooler. 天气越来越凉爽。 The wind became more and more heavily. 风变得越来越大。 Our school is
becoming more and more beautiful. 我们的学校变得越来越美丽。 3．在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。 如：Who is taller,Tim or Tom? 谁更高，Tim还是Tom? 4. “the +比较级……, the+比较级”，表示“越……越……”。 The more money you make, the more you spend. 钱你赚得越多，花得越多。 The sooner，the better. 越快越好。 5. 表示倍数的比较级用法： ①. A + be +倍数+ times + the + 形容词对应名词形式+ of + B. 如：The new building is three times the height of the old one. 这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高) ②. A + be +倍数+ times +as +原级+ as+ B. 如：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) ③. A + be + 序数词 +比较级+ than + B. 如：Our school is twice bigger than yours. 我们学校比你们学校大两倍。 6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最……”的意思。 句子中有表示范围的词或短语。如：of the three, in our class等等。 如：He is the tallest in our class. 他在我们班里是最高的。 7."否定词语+比较级"，"否定词语+ so… as"结构表示最高级含义。 Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing. 8. 比较级与最高级的转换： Mike is the most intelligent in his class. Mike is more intelligent than any other student in his class 7.修饰比较级和最高级的词 1）可修饰比较级的词 ①.a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。 ②. 还可以用表示倍数的词或度量名词作修饰语。 ③. 以上词(除by far)外，必须置于比较级形容词或副词的前面。 注意： 使用最高级要注意将主语包括在比较范围内。 (错) Tom is the tallest of his three brothers. (对) Tom is the tallest of the
three brothers. 2)下列词可修饰最高级：by far, far, much, mostly, almost。 This hat is nearly / almost the biggest. 注意： a. very可修饰最高级，但位置与much不同。 This is the very best. This is much the best. b. 序数词通常只修饰最高级。 Africa is the second largest continent. 8.要避免重复使用比较级。 (错) He is more cleverer than his brother. (对) He is more clever than his brother. (对) He is cleverer than his brother. 9.要避免将主语含在比较对象中。 (错) China is larger that any country in Asia. (对) China is larger than any other country in Asia. 10.要注意对应句型，遵循前后一致的原则。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out. 11.要注意冠词的使用，后有名词的时候，前面才有可能有冠词。 比较：Which is larger, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two
sisters. She is the taller of the two sisters. 10.连用词 much ,a little ,a bit, even
