五年级英语家教比较级最高级
一、形容词、副词的比较级和最高级的构成规则
1．一般单音节词和少数以-er，-ow结尾的双音节词，比较级在后面加-er，最高级在后面加-est；（1）单音节词
如：small→smaller→smallest short→shorter→shortest
tall→taller→tallest great→greater→greatest
（2）双音节词
如：clever→cleverer→cleverest narrow→narrower→narrowest
2．以不发音e结尾的单音节词，比较在原级后加-r，最高级在原级后加-st；
如：large→larger→largest nice→nicer→nicest able→abler→ablest
3．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，最高级加-est；如：big→bigger→biggest hot→hotter→hottest fat→fatter→fattest
4．以“辅音字母＋y”结尾的双音节词，把y改为i，比较级加-er，最高级加-est；
如：easy→easier→easiest heavy→heavier→heaviest
busy→busier→busiest happy→happier→happiest
5．其他双音节词和多音节词，比较级在前面加more，最高级在前面加most；
如：beautiful→more beautiful→most beautiful
different→more different→most different
easily→more easily→most easily
注意：（1）形容词最高级前通常必须用定冠词 the，副词最高级前可不用。
例句： The Sahara is the biggest desert in the world.
（2）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.
6．有少数形容词、副词的比较级和最高级是不规则的，必须熟记。
如：good→better→best well→better→best
bad→worse→worst ill→worse→worst
old→older/elder→oldest/eldest
many/much→more→most little→less→least
far →further/farther→ furthest/farthest
二、形容词、副词的比较级和最高级的用法
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.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。
6. 比较级与最高级的转换：

英语中的比较级与最高级 详解
比较级与最高级 1.as...as 与(not) as(so)...as as...as...句型中，as的词性 第一个as是副词，用在形容词和副词的原级前，常译为“同样地”。第二个as是连词，连接与前面句子结构相同的一个句子(相同部分常省略)，可译为“同..... He is as tall as his brother is (tall) . (后面的as 为连词) 只有在否定句中，第一个as才可换为so 改错: He is so tall as his brother.（X） 2.在比较状语从句中，主句和从句的句式结构一般是相同的 与as...as 句式中第二个as一样，than 也是连词。as和than这两个连词后面的从句的结构与前面的句子大部分情况下结构是相同的，相同部分可以省略。 He picked more apples than she did. 完整的表达为: He picked more apples than she picked apples. 后而的picked apples和前面相同，用did 替代。 He walked as slowly as she did.完整表达为: He walked as slowly as she walked slowly. she后面walked slowly与前面相同，用did替代。
3.谓语的替代 在as和than 引导的比较状语从句中，由于句式同前面 主句相同，为避免重复，常把主句中出现而从句中又出现的动词用do的适当形式来代替。 John speaks German as fluently as Mary does. 4.前后的比较对象应一致 不管后面连词是than 还是as,前后的比较对象应一致。The weather of Beijing is colder than Guangzhou. x than前面比较对象是“天气”，than 后面比较对象是“广州”，不能相比较。应改为: The weather of Bejing is colder than that of Guangzhou. 再如: His handwriting is as good as me. 应改为: His handwriting is as good as mine. 5.可以修饰比较级的词 常用来修饰比较级的词或短语有: Much,even,far,a little,a lot,a bit,by far,rather,any,still,a great deal等。 by far的用法: 用于强调，意为“...得多”“最最...”“显然”等，可修饰形容词或副词的比较级和最高级，通常置于其后，但是若比较级或最高级前有冠词，则可置于其前或其后。

Their house is much larger than ours. 另外，名词短语也可修饰比较级，说明程度。 I’m three years older than he. 特别提醒：very, quite, too不可修饰比较级。 ◇避免重复使用比较级。 误：He is more kinder to small animals than I. 正：He is much kinder to small animals than I. 误：He is more cleverer than his brother. 正：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来排除自身。 误：China is larger that any country in Asia. 正：China is larger than any other country in Asia. 误：John studies harder than any student in his class. 正：John studies harder than any other student in his class. 正：John studies harder than any of the other students in his class. 正：John studies harder than anyone else in 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. 误：In winter, the weather of Beijing is colder than it of Shanghai. 正：In winter, the weather of Beijing is colder than that of Shanghai. ◇“否定词 + 比较级”相当于最高级。
小学英语形容词的比较级
形容词的比较级 定义：形容词是用来修饰物体的形状，大小，长度，属性，特点等，位于名词的前面。而形容词的比较级表示两者间的比较。 结构： 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.西瓜比苹果大得多。 ③ very, quite一般只能修饰原级，不能修饰比较级。 2．“become + 形容词比较级+ and + 形容词比较级”是“变得越来越……”的意思，and连接同一个形容词的比较级。 如：It becomes warmer and warmer when spring comes. 春天来了，天气变得越来越暖和了。 注：表示“越来越……”时，若比较级是“原级+ er”构成的，则常用“比较级+ and + 比较级”形式；若比较级是“more + 原级”构成的，需用“more and more + 原级形式”。 如：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？ 形容词比较级构成规律 1．一般情况下，比较级在后面加； 如：small → smaller short → shorter 2．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，如：big →bigger hot→hotter 3．以不发音e结尾的单音节词，比较在原级后加； 如：large →larger nice →nicer 4．以“辅音字母＋y”结尾的双音节词，，比较级加； 如：easy →easier heavy→heavier 5．多数多音节词，比较级在前面加； 如：beautiful → more beautiful different → more different
