高考英语语法知识总结形容词和副词
高考英语语法知识总结形容词和副词高考英语语法知识总结(形容词和副词)如下:形容词、副词是每年高考必考点之一,近几年语境综合化程度越来越高,难度加大。
高考热点有:形容词、副词词义辨析;原级、比较级、最高级的使用;倍数的表达方法;比较等级的修饰语;多个形容词的排列顺序;常见形容词、副词的惯用法等。
关于形容词与副词这一考点,主要考查以下几个方面:1. 考查形容词和副词的基本用法形容词在句中一般作定语、表语、补语,而副词在句中主要作状语。
2. 考查形容词作定语的后置规律形容词作定语一般位于所修饰的名词前,但下列三种情况形容词要后置:①形容词短语作定语时;②表语形容词作定语时;③修饰复合不定代词时。
3. 考查多个形容词作定语的排序多个形容词修饰名词时,其排序规律是:(限定词+程度副词+) 描绘+大小(长短、高低)+形状+年龄(新旧)+颜色+国籍或产地+物质材料+类别或用途+名词。
4. 考查副词在句中的位置规律副词修饰形容词或其它副词时,一般位于被修饰词的前面,但enough却要放在被修饰的形容词或副词的后面。
5. 考查–ed形容词和-ing形容词的区别-ed形容词,通常说明人,意为“(某人)感到……”;-ing形容词通常说明事物,意为“(某事物)令人……”或“令人……的(事物)”。
6. 考查两种不同形式的副词的用法差异即考查与形容词同形的副词与形容词后加ly构成的副词的区别。
7. 考查形容词和副词的比较等级。
8. 考查比较等级的修饰语。
考点1:在具体的语境中辨析形容词与副词的语义从复现的频率来看,此点是高考对形容词、副词考查的第一大热点。
解答此类题关键是要分析具体的语境,结合基本词义、搭配等来选择正确的答案。

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。
