A．a lot of B．even C．more 【答案】B 【解析】句意：她甚至比她的朋友瘦。 考查副词辨析。 a lot of很多，修饰名词；even甚至；more更多，构成比较级。根据空后“thinner”是比较级“更瘦的”可知，该空应用来修饰比较级，even符合语境。故选B。 18．The sun finally comes out after days of rain.

A．longer and longer B．shorter and shorter C．long and long 【答案】A 【解析】句意：夏天白天变得越来越长。 考查常识、形容词辨析和形容词比较级的用法。longer and longer越来越长；shorter and shorter越来越短；long and long错误表达。根据常识可知，夏天白天会变得越来越长。此处应用“比较级+and+比较级”结构表示“越来越……”。故选A。 二、用所给词的适当形式填空 1．The weather is getting (cold) and (cold). 【答案】 colder colder 【解析】句意：天气变得越来越冷了。“cold”是形容词，意为“寒冷的”。句中“get”为系动词，后接形容词作表语，“比较级+and+比较级”是固定结构，意为“越来越……”，“cold”是单音节形容词，其比较级形式直接在词尾加“er”，即“colder”。故colder；colder。 2．There are (many) people in the park today than yesterday. 【答案】more 【解析】句意：今天公园里的人比昨天更多。 “than”是比较级的标志词，这表明句子是在将今天公园里的人数和昨天公园里的人数进行比较，所以要用“many”的比较级形式“more”，表示“更多”。故填more。 3．Mary is not (tall) than me. She is as (tall) as me. 【答案】 taller tall 【解析】句意：玛丽不比我高。她和我一样高。第一空，根据“than”可知，要用形容词“tall”的比较级“taller”，表示“更高的”；第二空，“as+形容词原级+as”是固定结构，意为“和……一样……”，所以用“tall”的原形。故填 taller；tall。 4．Which is (dangerous), a tiger or a lion? 【答案】more dangerous 【解析】句意：老虎和狮子，哪个更危险？根据“a tiger or a lion”可知是两者之间的比较，空格处需填入形容词比较级，dangerous的比较级是more dangerous。故填more dangerous。 5．We all know the Yellow River is the second (long) river in China. 【答案】longest 【解析】句意：众所周知，黄河是中国第二长河。根据“the second”可知，此处含有最高级的含义，结构为“the+序数词+形容词最高级”，此处指第二长河，应用longest。故填longest。 6．The more carefully you drive, the (safe) you are. 【答案】safer 【解析】句意：你开车越小心，就越安全。根据“The more carefully you drive, the ... you are.”可知，“the+比较级，the+比较级”表示“越……越……”，故此处应用safe的比较级safer。故填safer。 7．It was raining even (heavy) when we returned home yesterday. 【答案】more heavily 【解析】句意：昨天我们回家的时候，雨下得甚至更大了。rain是动词，意思是“下雨”，需要用副词来修饰。heavy是形容词，副词形式是heavily；even常用来修饰比较级，强调程度的进一步加深；heavily是多音节副词，其比较级是more heavily，表示“更大程度地；更猛烈地”。故填more heavily。 8．Yuan Longping, one of the (great) scientists, won respect all over the world. 【答案】greatest 【解析】句意：袁隆平，最伟大的科学家之一，赢得了全世界的尊重。one of the+形容词最高级+可数名词复数“最……的……之一”，此处应用great的最高级。故填greatest。 9．Wu Ming is the (tall) in his class. 【答案】tallest 【解析】句意：吴明是他们班最高的。根据“Wu Ming is the…in his class.”以及所给单词可知，此处说的是班级里最高的，应填形容词tall的最高级形式tallest。故填tallest。 10．Rick is my (good) friend in my class. 【答案】best 【解析】句意：里克是我班上最好的朋友。根据“Rick is my...friend in my class.”可知，此处用形容词最高级形式，good的最高级为best，best friend表示“最好的朋友”。故填best。 三、完成句子 1．安擅长数学。我比她擅长数学得多。 Ann is maths. I’m maths than her. 【答案】 good at much better at 【解析】根据中英文对照可知，空格处缺少“擅长”以及“擅长得多”的英文翻译。“擅长”对应英文“be good at”。“擅长得多”对应英文“much better at”，good比较级是better。故填good；at；much；better；at。 2．Their eyes are big. Tom’s eyes are bigger. (合并为一句) Tom’s eyes are than . 【答案】 bigger theirs 【解析】句意：他们的眼睛很大。汤姆的眼睛更大。本句也可表示“汤姆的眼睛比他们的大”；根据“than”可知，用形容词比较级bigger，than后用theirs代替their eyes。故填bigger；theirs。 3．Jack is the tallest student in his school. (用比较级改写句子) Jack is any other student in his school. 【答案】 taller than 【解析】句意：杰克是他学校里最高的学生。题目要求用比较级改写句子，即“杰克比他学校里任何其他学生都高”；the tallest是最高级形式，其对应的比较级是taller，“比……”用than。故填taller；than。 4．heavier  You   than   are   me(.) ______________________________________ 【答案】You are heavier than me. 【解析】根据所给标点可知，此句为陈述句，You“你”，作主语；heavier“更重的”，形容词，与系动词are连用；than“比”，me“我”。故答案为：You are heavier than me.“你比我重。” 5．我们坚信中国将越来越强大。 We believe China will be . 【答案】stronger and stronger 【解析】对照中英文提示可知，缺少“越来越强大”，可以用“比较级+and+比较级”结构。“强大”用形容词strong，作表语，比较级为stronger。故填stronger and stronger。 6．Jim is taller than the other two.（改为同义句） Jim is of the three. 【答案】 the tallest 【解析】句意：Jim比另外两个人都高。也就是说Jim在他们三个人中是最高的。题干为用比较级表示最高级，所以可以直接用tall的最高级tallest进行同义句转换。此外，形容词的最高级前通常要加定冠词the。故填the；tallest。 7．I think Shanghai is bigger than any other city in China. (改为同义句) I think Shanghai is city in China. 【答案】the biggest 【解析】句意：我认为上海比中国其他任何城市都大。改为同义句，此处表达的是上海在中国城市中是最大的，应使用形容词最高级形式：the biggest。故填the biggest。 8．English is important. Chinese is important, too. (将两句合并成一个句子) English is important Chinese. 【答案】 as as 【解析】句意：英语很重要。语文也很重要。“as + 形容词原级 + as”是一个常用结构，意为“和……一样” ，用于两者之间的同级比较。在此句中“as important as”表明英语与语文一样重要，故填as；as。 9．Cynthia is 13 years old. Susan is 13 years old, too. (合并一句) Cynthia is old Susan. 【答案】 as as 【解析】句意：辛西娅13岁了。苏珊也13岁了。根据内容可知，Cynthia和Susan年龄一样大，as......as“和……一样”。故填as；as。 10．哪一个更大，太阳还是地球? Which is , the sun or the earth? 【答案】bigger 【解析】据句意可知，此处是在对太阳和地球的大小进行比较，询问“哪一个更大”，所以需要用形容词“big”的比较级形式。“big”的比较级是“bigger”，用来表示两者中更大的一个。故填bigger。 题型一 补全对话 根据下面对话中的情境，在每个空白处填入一个适当的语句，使对话恢复完整。 Teacher: I’m going to test you now by asking a few questions.
