(完整版)动词的比较级和最高级变化规则
(完整版)动词的比较级和最高级变化规则一、概述在英语中，比较级和最高级是用来对比事物的相对程度的形式。
动词的比较级和最高级变化规则涉及到动词在不同程度上的表达方式。
本文将详细介绍动词的比较级和最高级的变化规则。
二、比较级变化规则比较级是表示两种或两种以上事物相对程度的形式。
动词的比较级变化通常遵循以下规则：1. 在动词的后面加上"-er"表示比较级。
例如：tall（高）- taller （更高）。
2. 在以一个辅音字母结尾的重读闭音节动词后面，双写最后一个辅音字母，再加上"er"。
例如：big（大）- bigger（更大）。
3. 在以"e"结尾的动词后面直接加上"r"。
例如：nice（好）- nicer（更好）。
三、最高级变化规则最高级是表示三种或三种以上事物相对程度的形式。
动词的最高级变化通常遵循以下规则：1. 在动词的后面加上"-est"表示最高级。
例如：tall（高）- tallest（最高）。
2. 在以一个辅音字母结尾的重读闭音节动词后面，双写最后一个辅音字母，再加上"est"。
例如：big（大）- biggest（最大）。
3. 在以"e"结尾的动词后面直接加上"st"。
例如：nice（好）- nicest（最好）。
四、不规则变化除了上述规则，还有一些动词变化的方式比较特殊，需要根据具体情况进行记忆：1. 不规则动词的比较级和最高级通常是通过改变单词本身的形式来实现的。
例如：good（好）- better（更好）- best（最好）。
2. 一些动词在比较级和最高级形式上的变化比较特殊，需要进行特别记忆。
例如：well（好）- better（更好）- best（最好）。
五、总结动词的比较级和最高级变化规则可以帮助我们更准确地描述事物的相对程度。

一倍数表达法是历届高考的热点。
当我们要表达甲是乙的几倍时，通常可使用以下句型：1. 倍数+ as + 形容词或副词的原级+ as + 其他。
这种结构又常演变成下列两类：①倍数+ as + many + 可数名词复数+ as；②倍数+ as +much + 不可数名词+ as。
如：There are seven times as many people as I expected.是我预料的人数的七倍。
There is five times as much coffee in this glass as in that one.这个杯子里的咖啡是那个杯子里的五倍。
2. 倍数+ 形容词（或副词）的比较级+ than + 其他。
如：The hall is five times bigger than our classroom. 这个大厅的面积比我们教室大五倍。

如：The size of the newly broadened square is four times that of the previous one.新扩建的广场为以前的四倍大。
5. 倍数+what从句。
如：The production is now three times what it was ten years ago.现在的产量是十年前的三倍。

Lesson Seven 比较级、最高级、倍数表达
Lesson Seven Comparative & Superlative、倍数的表达(图表式作文)ComparisonsKey ConceptsComparisons indicate degrees of difference or similarity with adjectives and adverbs. So there are equal and unequal comparisons.1. Equal comparisonsHis car runs as fast as a race car. (adverb)They sing as well as we. (adverb)His job is not so / as difficult as mine. (adjective)Note:1) Sometimes we may see “so” instead of “as” before the adjective or adverb in negative comparison.Eg. He is not so tall as his father.2) Remember that subject form of the pronoun will always be used after “as” in standard English.Eg. You are as old as she.My house is of the same height as his.He speaks the same language as she.She takes the same course as her husband.Note:The opposite of “the same as” is “different from”.Eg. My nationality is different from yours.2. Unequal comparisonsThe following rules generally apply to unequal comparative structures:1) Add “-er”to the adjective base of most one- and two- syllable adjectives, eg. thick—thicker; soon—sooner.2) Use the form “more + adjective” for most three-syllable adjectives, eg. more beautiful; more important.3) Use the form “more + adjective” for adjectives ending in the following suffixes: -ed, -ful, -ing, -ish, -ous; eg. more useful; more boring; more cautious.4) When adding “-er”, double the final consonant of one-syllable adjectives which end I asingle consonant (except w, x, z) and are preceded by a single vowel, eg. big—bigger; hot—hotter.5) When an adjective ends in a consonant with “y”, change the “y” to “i” and add “-er”, eg. happy—happier; dry—drier.He speaks Spanish more fluently than I. (adv.)This chair is more beautiful than that one. (adj.)He visits his family less frequently than she does. (adv.)Unequal comparisons can be further intensified by adding “much”or “far”before the comparative form.Eg. A watermelon is much sweeter than a lemon.Harry’s watch is far more expensive than mine.Note: Nouns can also be used in comparisons. Be sure to use the determiner correctly depending on whether the adjectives are countable or uncountable.February has fewer days than March.He earns as much money as his brother.They have as few classes as we.Their job allows them less freedom than ours does.3. Illogical comparisonsAn illogical comparison is one in which unlike things have been compared. Be sure that the items being compared belong to the same category. These forms can be divided into three categories:1) possessives, 2) that of, 3) those ofEg. His drawings ar as perfect as his instructor. (×) (This sentence compares drawings with instructor.)His drawings are as perfect as his instructor’s. (√)The salary of a professor is higher than a secretary. (×) (This sentence compares salary with secretary.)The salary of a professor is higher than that of a secretary. (√)The duties of a policeman are more dangerous than a teacher. (×) (This sentence compares duties with teacher.)The duties of a policeman are more dangerous than those of a teacher. (√)4. Multiple number comparativesNumber multiples include: half, twice, three times, four times, etc. Study the following rule.Fred ate three times as many oysters as Barney.Jerome has half as many records now as I had last year.Note: It is incorrect to say: twice more than, etc.5. Double comparativesThese sentences begin with a comparative construction, and thus the second clause must also begin with a comparative.The bigger they are, the harder they fall.The sooner you take your medicine, the better you will feel.The more he rowed the boat, the farther away he got.The more he slept, the more irritable he became.描写说明文试题形式一般是给出一个或几个图画或图表。

比较级和最高级的用法
比较级和最高级的用法英语句子中，将比较两个主体相比较的方法叫做“比较句型”。
典型的是指形容词或副词所表示的质、量或关系的增加：其中，像“A比B更……”的表达方式称为比较级；而“A最……”的表达方式则称为最高级。
基本比较句型一、两者相比（甲=乙，表示甲和乙一样）用“甲as+原级+as乙”句型1、 Tom is as tall as Mike.2、（倍数+as+形容词/副词原级+ as）This rope is three times as long as that one.3、（倍数+ the + n. + of）This rope is three times the length of that one.二、两者相比（甲<乙，表示甲不如乙）用“甲+not as(so) +原级+as+乙”或“less than”表示1、I didn’t do my homework so(as) carefully as you.2、The picture is less attractive than that one.三、两者相比（甲>乙，表示甲比乙强）用“甲+比较级+than+乙”表示1、O ur city is more beautiful than any other city in our country.2、T his rope is three times longer than that one.（倍数+形容词/副词比较级+than）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。
a)The population of Shanghai is larger than that of Beijing.b)It is easier to make a plan than to carry it out.c)His shirt is more expensive than mine(my shirt).(如果主语是物主代词+名词，那么后面要用名词性物主代词.)d)He is older than me.（than是介词，后面是人称代词时用宾格）e)Skiing is more exciting than skating. (比较对象可以是名词，短语，从句)②为了避免重复，在从句中常用one, that, those等词来代替前面提过的名词。
