A．as well as B．as good as C．as bad as D．as badly as 【答案】A 【详解】句意：许多英语学习者英语说得相当好，但不像英国的本地人说得那么好。 修饰实义动词speak需用副词，good和bad是形容词，排除B、C；根据前半句quite well可知此处表示说得不如当地人好，well为副词“好”，符合语境，badly为副词“坏地”，不符合语境。故选A。 2．My sister is ________ tall ________ my father, but she is taller than my mother. A．as; as B．not so; as C．not as; so D．more; than 【答案】B 【详解】句意：我姐姐不如我爸爸高，但是她比我妈妈高。 as; as和……一样；not so; as不如……（否定比较结构）；not as; so（搭配错误，应为not as…as）；more; than比……更（比较级结构）。根据转折连词“but”可知，前后分句语意存在转折。后半句表示“比妈妈高”，前半句应表示“不如爸爸高”，才能构成“虽不及父亲高，但高于母亲”的对比逻辑。“not so…as”意为“不如……”，符合语境。 3．My new pencil case is as ________ as yours. But mine is more beautiful than yours. A．big B．bigger C．biggest D．the biggest 【答案】A 【详解】句意：我的新铅笔盒和你的一样大。但是我的比你的更漂亮。 根据“My new pencil case is as ___ as yours.” 可知，“as + 形容词原级 + as” 为固定结构，表示 “和…… 一样”，中间需要填入形容词原级。 4．He runs ________ fast ________ his brother. They always tie (平局) in the race. A．so; as B．as; as C．as; so D．not as; as 【答案】B 【详解】句意：他跑得和他哥哥一样快。他们总是在比赛中打成平局。 so…as常用于否定句和疑问句；as…as表示“和……一样”，用于原级比较；as…so搭配错误；not as…as表示“不如……”。根据后句“They always tie in the race”可知两人速度相同，肯定句中表示“和……一样……”，应用结构“as+副词原级+as”。 5．Mary looks so slim. She eats the ________ meat and the ________ vegetables of us. A．least; most B．fewest; most C．most; fewest D．fewest; least 【答案】A 【详解】句意：玛丽看起来很苗条。她在我们当中吃最少的肉和最多的蔬菜。 least最少的（修饰不可数名词）；most最多的；fewest最少的（修饰可数名词复数）。meat是不可数名词，不能用fewest修饰；根据“slim”可知为了保持苗条应吃肉少、蔬菜多，因此第一空填least，第二空填most。 6．—Lily, what do you think of Chengdu and Chongqing? —As a guide, I think Chengdu is ________ lively ________ Chongqing. I like both of them. A．less; than B．as; as C．more; than 【答案】B 【详解】句意：——莉莉，你觉得成都和重庆怎么样？——作为一名导游，我认为成都和重庆一样充满活力。我都喜欢它们。 less…than不如……；as...as和……一样；more than比……更……。根据答语后句“I like both of them.”可知，说话者对两个城市持同等喜爱的态度，推测前句是在表达两个城市活力程度相当，应填as; as。 7．Amy sings ________ beautifully ________ her sister. They both have sweet voices. A．so; as B．more; than C．as; as D．less; than 【答案】C 【详解】句意：埃米唱歌和她姐姐一样动听。她们都有甜美的嗓音。 so…as…用于否定句：not so…as不如……；more…than…比……更……；as…as…和……一样……；less…than…不如……，比……更差。此句为肯定句，结合后句“They both have sweet voices.”，说明两人歌唱水平相当，用as…as。 8．Kate dances as _________ as Lucy. They are both good at dancing. A．well B．better C．the better D．best 【答案】A 【详解】句意：凯特跳舞和露西一样好。她们都擅长跳舞。 well好地，副词；better更好地，比较级；the better更好，比较级；best最好地，最高级。as+形容词原级/副词原级+as“和……一样……”，固定搭配；此处应用副词修饰动词dances，故用well。 9．The ________ you practice speaking English, the ________ you will learn it. A．more; better B．much; well C．most; best D．many; good 【答案】A 【详解】句意：你练习说英语越多，你将会学得越好。 more更多，比较级；better更好，比较级；much多，原级；well好，原级；most最多，最高级；best最好，最高级；many多，原级；good好，原级。本题考查“the + 比较级，the + 比较级”结构，表示“越……，就越……”。此结构要求两处均使用形容词/副词比较级。应填more；better。 10．This story is ________ interesting that all of us want to read it again. A．such B．so C．very D．too 【答案】B 【详解】句意：这个故事如此有趣，我们所有人都想再读一遍。 such如此；so如此；very非常；too太。根据句中“that all of us want to read it again”以及形容词“interesting”可知，本句适用so + adj. + that...“如此……以至于……”结构，应填so。 11．Lucy’s schoolbag is ________ as Lily’s. They are both pink and the same size. A．as beautiful B．more beautiful C．most beautiful D．so beautiful 【答案】A 【详解】句意：露西的书包和莉莉的一样漂亮。它们都是粉色的，大小也一样。 as…as用于原级比较，表示“和……一样”；more beautiful是比较级；most beautiful是最高级；so…as多用于否定句。结合后文两者外观、大小一致的语境，此处表达二者的书包一样漂亮，应填as beautiful。 12．There is ________ water in this bottle than in that one. Let’s buy some more. A．few B．fewer C．little D．less 【答案】D 【详解】句意：这个瓶子里的水比那个瓶子里的少。我们再去买一些吧。 few少的；fewer更少的；little少的；less更少的。根据句中的“than”可知应用比较级；又因为“water”是不可数名词，fewer修饰可数名词复数，less修饰不可数名词，应填less。 13．The new type of car is not as ________ as the old one, and it’s more environmentally friendly. A．expensive B．less expensive C．more expensive 【答案】A 【详解】句意：这种新型汽车不像旧款那么贵，而且更环保。 expensive昂贵的；less expensive更便宜的；more expensive更贵的。根据句中固定结构‌not as + 形容词原级 + as‌（和……不一样）的语法规则，此处需要填入形容词原级，应选‌expensive‌。 14．—How many students can the hall hold? —________ 500. It’s not very big. A．At most B．At least C．More than D．As many as 【答案】A 【详解】句意：——这个大厅能容纳多少名学生？——最多500人，它不是很大。 At most至多；At least至少；More than超过；As many as多达。根据后文“It’s not very big.”可知大厅空间不大，容纳人数存在上限，只有At most符合语境，其余短语均暗示人数较多或下限为500，和后半句语义矛盾。故选A。 15．—Do you have ________ free time than before? —Yes. Because I have ________ homework to do. A．more; fewer B．less; more C．fewer; more D．less; fewer 【答案】B 【详解】句意：——你现在的空闲时间比以前更少吗？——是的。因为我有更多的作业要做。 less更少，修饰不可数名词；more更多，修饰可数或不可数名词；fewer更少，修饰可数名词复数。“free time”和“homework” 均为不可数名词，fewer修饰可数名词复数，因此排除fewer，根据句意逻辑，作业变多导致空闲时间变少，选项B符合语境， 16．Swimming is not ________ difficult as playing ball games for me. A．so B．such C．too D．quite 【答案】A 【详解】句意：对我来说，游泳不像球类运动那么难。 so如此，那么；such这样的；too太；quite相当。固定搭配“not as/so...as”意为“不如……那样……”，中间接形容词原级。根据句中的not和as可知此处应用so或as，选项中只有so符合语境。 17．Chinese students have ________ weeks ________ in winter than American students. A．fewer; off B．less; on C．more; off D．more; on 【答案】C 【详解】句意：中国学生在冬季比美国学生有更多的休假周数。 weeks是可数名词复数，less用来修饰不可数名词，排除B；have...off为固定搭配，意为“休假”，排除D；根据实际情况，中国寒假通常比美国寒假时间长，fewer意为“更少”，语意不符，应用表示“更多”的比较级。应选more; off。 18．The new school library is much ________ the old one, but it has many more books. A．as big as B．bigger than C．smaller than D．not as big as 【答案】C 【详解】句意：这座新校图书馆比旧图书馆小得多，但它的藏书数量要多很多。 as big as和……一样大；bigger than比……更大；smaller than比……更小；not as big as不如……大。much只能修饰形容词/副词比较级，用来加强比较的程度，排除选项A和D。后半句but表转折，若选bigger than（更大），前后都是优势，逻辑冲突，排除。应填smaller than。 19．The ________ friends you have, the happier you will be. A．many B．more C．most D．much 【答案】B 【详解】句意：朋友越多，你就越快乐。 many许多（原级）；more更多（比较级）；most最多（最高级）；much许多（修饰不可数名词）。此处是固定句型“the+比较级，the+比较级”，符合该结构的只有more。 20．The red car costs ________ the blue one, but it’s more fuel‑efficient. A．as much as B．as many as C．so much as D．so many as 【答案】A 【详解】句意：这辆红色汽车的价格和蓝色汽车一样，但它的燃油效率更高。 much大量（修饰不可数名词）；many大量（修饰可数名词复数）；so much as和……一样（多用于否定句）；so many as和……一样多（多用于否定句，修饰可数名词）。句中价格为不可数概念，且为肯定句，应选as much as。 21．This lake isn’t as large ________ the ocean, but it’s the ________ freshwater lake in this country. A．as; largest B．like; largest C．like; large D．as; large 【答案】A 【详解】句意：这个湖不如海洋大，但它是这个国家最大的淡水湖。 as像，如；largest最高级；like像；large原级。句中“isn’t as large...the ocean”提示第一空考查短语not as...as...，意为“不如……”；范围状语“in this country”及空前定冠词the提示第二空应用形容词最高级 largest。故选 A。 22．Suzy’s painting isn’t as ________ as her classmates’, but her idea is ________ of all. A．colourful; the best B．colourful; best C．more colourfully; the better D．most colourful; best 【答案】A 【详解】句意：Suzy的画不如她同学的画色彩丰富，但她的想法是所有当中最好的。 第一空：as...as中间用原级，且主语是painting，系动词是is，故用形容词colourful；第二空，根据of all可知是在所有之中比较，用最高级，且最高级前加the，故用the best。 23．Sam is ________ his twin brother Tom, because Sam always tells us jokes but Tom hardly ever laughs. A．as serious as B．not as serious as C．more serious than D．not more serious than 【答案】B 【详解】句意：萨姆不如他的双胞胎兄弟汤姆严肃，因为萨姆总是给我们讲笑话，但汤姆几乎从不笑。 as serious as和……一样严肃；not as serious as不如……严肃；more serious than比……更严肃；not more serious than不比……更严肃。根据“Sam always tells us jokes”可知萨姆幽默，而“Tom hardly ever laughs”表明汤姆严肃，因此萨姆不如汤姆严肃。 24．— Is your hair as________ as Mary’s? — No, her hair is________than mine. A．longer; long B．long; long C．long; longer D．longer; longer 【答案】C 【详解】句意：——你的头发和玛丽的一样长吗？——不，她的头发比我的更长。 考查形容词原级和比较级的用法。longer更长的；long长的。第一空“as…as”结构要求中间用形容词原级，因此用long；第二空出现“than”，需要用形容词比较级，因此用longer。故选C。 25．—Is that your brother? —Yes.
