新教材八年级英语下学期语法精讲精练（人教版2024） Unit4形容词、副词比较级与最高级 语法精讲 一、比较级与最高级变化规则 （1）规则变化： 单音节/部分双音节：直接+er/est，如tall→taller→tallest。 以e结尾：+r/st，如nice→nicer→nicest。 辅+y结尾：变y为i+er/est，如easy→easier→easiest。 重读闭音节（辅+元+辅）：双写尾字母+er/est，如big→bigger→biggest。 多音节/部分双音节：more/most+原词，如amazing→more amazing→most amazing。 （2）不规则变化（必记）： good/well→better→best； bad/badly→worse→worst。 many/much→more→most； little→less→least。 far→farther/further→farthest/furthest。 二、常用句型（必记） （1）比较级（两者对比）：A+be+比较级+than+B；A+实义动词+副词比较级+than+B。 例：The Pacific Ocean is deeper than the Atlantic Ocean。 例：He runs faster than his brother。 （2）最高级（三者及以上）：A+be+the+最高级+范围（in/of/among...）；A+实义动词+（the）副词最高级+范围。 例：Qomolangma is the highest mountain in the world。 例：She sings (the) most beautifully in the class。 （3）渐进变化：get/become/grow+比较级，表“越来越…”。 例：The wind is getting stronger and stronger。 94两者同级比较：as+原级+as；否定not as/so+原级+as。 例：This river is as long as that one。 三、大数字表达（描述自然尺寸） 千：thousand；百万：million；十亿：billion，三位一逗，从右往左读。 例：6,300→six thousand three hundred；9,000,000→nine million。 尺寸表达：基数词+单位+long/wide/high/deep，如8,848.86 meters high。 四、易错点提醒 （1）最高级前通常加the；副词最高级的the可省，教材中多保留。 （2）farther表距离更远；further表程度更深、更进一步。 （3）比较级后接than，最高级需明确比较范围（in/of/among...）。 （4）避免双重比较：不能more taller、most tallest。 五、课堂应用建议 （1）结合自然奇观（珠峰、撒哈拉、长江等）例句，让学生描述比较。 （2）设计小组任务：用比较级/最高级描述一处自然景观并展示。 （3）练习数字表达：给出景观数据，让学生快速朗读并比较。 中考真题 1．（2025·江苏无锡·中考真题）But it only gets ________.

考查名词单复数和比较级固定搭配。第一空：one of the + 最高级 + 名词复数，表示“最……的……之一”，因此需用复数名词cities。第二空：“比较级 + and + 比较级”表示“越来越……”，better and better 是固定搭配，more better 语法错误。故选C。 15．A 【详解】句意：小明在他班里所有的学生中书写得最认真。 考查介词辨析和副词的最高级。in在……里，表示地点；of……的，表示范围。根据“all the students in his class”可知，此处表示“他班所有的学生中”，表范围，因此空一用of。 由“in his class”可知，这是在三者或三者以上进行比较，因此空二用副词最高级the most carefully，副词的最高级前可不加the。故选A。 16．D 【详解】句意：——哪个最大，太阳，地球还是月球？——当然是太阳。 考查最高级的用法。根据“the sun, the earth or the moon”可知，此处是三者之间的比较，应用最高级，形容词的最高级前面加定冠词the，故选D。 17．D 【详解】句意：月球上的一切都比地球上的更明亮。

boys.”可知此处用副词最高级，the可省略。故填the most carefully/most carefully。 22．long 【详解】句意：我的头发和莉莉的一样长。我们是双胞胎姐妹。as...as中间加原级，此处作be动词的表语用形容词原级long。故填long。 23．younger

【详解】句意：这件蓝色的外套是布店里最贵的一件。根据“in the cloth store”可知，三者以上的比较用最高级，且最高级前要加冠词the，故填the most expensive。 28．more dangerous 【详解】句意：我认为游泳比跑步更危险。这是主系表结构，所以用形容词dangerous“危险的”，且由“than”可知是比较级，dangerous是多音节词，比较级在前面加more。故填more dangerous。 29．taller 【详解】句意：这个男孩比他班上其他任何男孩都高。根据空后than“比”可知，空处形容词用比较级，在句中作表语，tall应变形为taller。故填taller。

other+名词”意为“比其他任何一个都……”。longer“更长的”。故填longer；any；other。 32． the largest city 【详解】句意：多伦多是加拿大的一个大城市。根据句意可知，改为最高级，即“多伦多是加拿大最大的一个大城市”，空格处为“最大的城市”，此时应用large的最高级largest，最高级前往往要加定冠词the，故“最大的城市”the largest city。故填the；largest；city。 33． older than 【详解】句意：贝蒂十岁了。大卫十二岁了。即“大卫比贝蒂年长两岁”，需用比较级。older“更年长的”，than“比”。故填older；than。 34． as tall as 【详解】句意：李华是我们班最高的。同义句可以改为“在我们班，没有人和李华一样高”，tall“高的”，形容词，as...as...“和……一样……”，两个as之间使用形容词原级。故填as；tall；as。 35． less interesting than 【详解】句意：收音机不如电脑有趣。原句使用的是not as…as…意为“不像……一样……”，可改为比较级形式，less interesting than computers，也表示“不如电脑有趣”，故填less；interesting；than。 36． more beautiful any other city 【详解】句意：这是中国最美丽的城市。根据题干要求改为同义句，可用“比较级+than+any other+单数名词”替换“the+形容词性最高级”。第一、第二空填形容词比较级“more beautiful”；后面三个空填写表示“任何一个其它城市”，即“any other city”。故填more；beautiful；any；other；city。 37． as useful as 【详解】句意：中文很有用。英语也很有用。合为一句即“汉语和英语一样有用”，可以用“as+形容词原级useful+as”的结构，故填as；useful；as。 38． shorter than 【详解】句意：我比迈克高。原句也可表达为迈克比我矮，short“矮的”，两者相比较用比较级shorter，后跟介词than“比”。故填shorter；than。 39． earlier than 【详解】句意：莉莉很早到学校。彼得更早到学校。根据“Lily got to school early. Peter got to school earlier.”可知，彼得比莉莉到校更早，使用比较级，earlier“更早地”，than“比”。故填earlier；than。 40． runs faster than 【详解】句意：汤姆跑得很快。吉姆跑得更快。合并为一句时，用“比较级 + than”结构表达两者间的比较。原句时态为一般现在时，主语Jim是第三人称单数，动词run要用第三人称单数形式runs；“更快”用faster，后接than引出比较对象Tom。故填runs；faster；than。 41．longest 42．important 43．more difficult 44．worse 45．most famous 【导语】本文主要介绍三江源国家公园。 41．句意：长江是三条河流中最长的。根据“The Yangtze River is the...of the three.”可知，三者的比较，且空前有the，所以用最高级，故填longest。 42．句意：它和我们的生命一样重要。此处在句中作表语，用于as...as结构中，使用形容词原级，故填important。 43．句意：对动物和人类来说，那里的生活也比其他地方困难得多。根据“than”可知，此处用形容词比较级作表语，故填more difficult。 44．句意：为了阻止事情变得更糟，我们的政府已经采取了很多方法，例如，建立三江源国家公园。根据“To stop things from getting...”可知，此处暗含比较含义，为了阻止事情变得更糟，故填worse。 45．句意：我国正在尽最大努力使三江源国家公园成为世界上最著名的公园之一。此处是“one of the+最高级+名词复数”结构，故填most famous。 学科网（北京）股份有限公司 $ 新教材八年级英语下学期语法精讲精练（人教版2024） Unit4形容词、副词比较级与最高级 语法精讲 一、比较级与最高级变化规则 （1）规则变化： 单音节/部分双音节：直接+er/est，如tall→taller→tallest。 以e结尾：+r/st，如nice→nicer→nicest。 辅+y结尾：变y为i+er/est，如easy→easier→easiest。 重读闭音节（辅+元+辅）：双写尾字母+er/est，如big→bigger→biggest。 多音节/部分双音节：more/most+原词，如amazing→more amazing→most amazing。 （2）不规则变化（必记）： good/well→better→best； bad/badly→worse→worst。 many/much→more→most； little→less→least。 far→farther/further→farthest/furthest。 二、常用句型（必记） （1）比较级（两者对比）：A+be+比较级+than+B；A+实义动词+副词比较级+than+B。 例：The Pacific Ocean is deeper than the Atlantic Ocean。 例：He runs faster than his brother。 （2）最高级（三者及以上）：A+be+the+最高级+范围（in/of/among...）；A+实义动词+（the）副词最高级+范围。 例：Qomolangma is the highest mountain in the world。 例：She sings (the) most beautifully in the class。 （3）渐进变化：get/become/grow+比较级，表“越来越…”。 例：The wind is getting stronger and stronger。 94两者同级比较：as+原级+as；否定not as/so+原级+as。 例：This river is as long as that one。 三、大数字表达（描述自然尺寸） 千：thousand；百万：million；十亿：billion，三位一逗，从右往左读。 例：6,300→six thousand three hundred；9,000,000→nine million。 尺寸表达：基数词+单位+long/wide/high/deep，如8,848.86 meters high。 四、易错点提醒 （1）最高级前通常加the；副词最高级的the可省，教材中多保留。 （2）farther表距离更远；further表程度更深、更进一步。 （3）比较级后接than，最高级需明确比较范围（in/of/among...）。 （4）避免双重比较：不能more taller、most tallest。 五、课堂应用建议 （1）结合自然奇观（珠峰、撒哈拉、长江等）例句，让学生描述比较。 （2）设计小组任务：用比较级/最高级描述一处自然景观并展示。 （3）练习数字表达：给出景观数据，让学生快速朗读并比较。 中考真题 1．（2025·江苏无锡·中考真题）But it only gets ________.
