一、用所给单词的正确形式填空
1．Ning Zetao from Henan got great ________ (achieve) in swimming.
【答案】achievements
【详解】句意：来自河南的宁泽涛在游泳项目上取得了很了不起的成绩。“成
绩”achievement，是可数名词，great前无限定词，用复数形式。故填achievements。
2．Li Ming is one of ________ (clever) boys in our class.
【答案】the cleverest
【详解】句意：李明是我们班最聪明的男孩之一。根据“one of ...boys in our class”可知，
此处是one of the+形容词做高级+可数名词复数+比较范围，表示“……中……最……之
一”，clever的最高级cleverest。故填the cleverest。
3．The earth receives ________ (little) heat from the sun in winter than in summer.
【答案】less
【详解】句意：地球在冬天从太阳接收的热量比夏天少。根据than可知，此处用little的比
较级less。故填less。
4．He said that it was ________ (happy) day in his life.
【答案】the happiest
【详解】句意：他说这是他一生中最开心的一天。 根据“in his life”在他的一生中，可知
指的是范围，设空处应用形容词最高级，“happy”的最高级为happiest，最高级前面应加定
冠词the，the happiest作定语修饰名词“day”，故填the happiest。
5．They wanted to challenge themselves in the face of ________ (difficulty).
【答案】difficulties
【详解】句意：他们想在困难面前挑战自己。通过“in the face of”可知，空格处应填名词；
difficulty“困难”，可数名词，根据语境可知，此处应用复数表达不止一种困难，difficulty
的复数为“difficulties”。故填difficulties。
6．The boy wanted to become a famous ________（climb）.
【答案】climber
【详解】句意：这个男孩想成为一名著名的登山者。根据空前“The boy wanted to become”
可知，空处应是climber“登山者”，可数名词；因之前有不定冠词a修饰，故名词应用单数
形式。故填climber。
7．One of the main ________(reason)is that he wants to become brave.
【答案】reasons
【详解】句意：主要原因之一是他想变得勇敢。根据“one of+可数名词复数”表示“……之一”可知，应该填的是reason“原因”的复数reasons，故填reasons。
8．Shanghai is one of the ________ (large) cities in the world.
【答案】largest
【详解】句意：上海是世界上最大的城市之一。根据语境可知，上海是最大的城市之一，
“one of the+形容词最高级+可数名词复数”表示“最……的……之一”，空处需填形容词
最高级，largest为形容词large“大的”最高级。故填largest。
9．The sun is ________ (bright) than all the other stars because it is ________ (near) to the earth.
【答案】 brighter the nearest
【详解】句意：太阳比所有其他恒星都亮，因为它离地球最近。根据“than”可知其前的空
格应用比较级，形容词bright的比较级为brighter；根据“because it is…to the earth.”可知此
处指太阳是离地球最近的那个恒星，应用形容词near的最高级nearest，其前要加定冠词
the表示“最近的那个”。故填brighter；the nearest。
10．Tom is ________ (young) than any other student in his class. So he is ________ (young) in
his class.
【答案】 younger the youngest
【详解】句意：汤姆比班上任何一个学生都年轻。所以他是班上最小的。提示词young“年
轻的”，形容词，比较级为younger，最高级为youngest。根据“than”可知，第一空要用比
较级younger；根据“in his class”可知第二空要用最高级youngest，形容词最高级前要加定
冠词the。故填younger；the youngest。
二、汉译英。
11．当你面对困难时，你一定要勇敢。
You must be brave ________ ________ ________ ________ difficulties.
【答案】 in the face of
【详解】句意：通过中英对照可知，空格处应填“面对”。“in the face of”表示“面对”，

12．虽然我们都尽了最大的努力，但还是输了这场比赛。
________ ________ we all tried our best, we lost the game.
【答案】 Even though
【详解】根据“虽然……但”可知是让步状语从句，用“even though”引导状语从句，句首
首字母大写。故填Even; though。
13．他们冒着生命危险救了那个男孩。
They ________ ________ ________ to save that boy.
【答案】 risked their lives
【详解】表示“冒着生命的危险去做某事”用短语“risk one’s life to do”。句子是一般过去
时，动词用过去式“risked”。主语“他们”是复数概念，用物主代词“their”表示“他们
的”，宾语用复数名词“lives”。故填risked；their；lives。
14．主要的原因之一是她想挑战自己。One of the main reasons is that she wants to ________ ________.
【答案】 challenge herself
【详解】根据中英文对照可知，空格处应填“挑战她自己”；challenge“挑战”，可作动词，
“want to do”表示“想做……”，故空格处应用动词原形challenge；根据“she”可知，此处
填“herself”表示“她自己”，反身代词。故填challenge；herself。
15．你不能放弃你的梦想。
You can’t ________ ________ your dream.
【答案】 give up
【详解】放弃：give up，固定短语；句子的“can’t”为情态动词，其后跟动词原形。故填
give；up。

故填How；high。
17．Radios are not as interesting as computers.（改为同义句）
Radios are ________ ________ ________ computers.
【答案】 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。
18．It is the most beautiful city in China.（改为同义句）
It is ________ ________ than ________ ________ ________ in China.
【答案】 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。
19．He is not so good at English as me. (改为同义句)
I am ________ ________ English ________ ________.
【答案】 better at than him
【详解】句意：他英语不如我好。根据题干，改为同义句，可表达为“我比他更擅长英
语”，be better at“更擅长”，than“比”；him“他”作宾语，故填better；at；than；him。
20．Chinese is useful. English is useful, too. (合并为一句)
Chinese is ________ ________ ________ English.
【答案】 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

能力提升
一、单项选择
21．He ________ in the end, and his ________ made us excited.
A．succeeded; success B．succeeded; successful
C．success; succeed D．successful; succeed
【答案】A
【详解】句意：他最后成功了，他的成功使我们兴奋。
考查词汇辨析。succeeded成功，动词；success成功，名词；successful成功的，形容词。
分析句子结构可知第一空在句中作谓语，用动词succeeded；第二空在句中作主语，用名词
success。故选A。
22．There are many places of interest in Beijing, ________ the Great Wall.
A．include B．included C．including D．includes
【答案】C
【详解】句意：北京有许多名胜古迹，包括长城。

括，-ing形式或介词；includes动词第三人称单数形式。根据“There are many places of
interest in Beijing, ... the Great Wall.”可知此处指包括长城在内的许多名胜古迹，此处用介词
including。故选C。

A．Of; most carefully B．In; the most carefully
C．Of; very carefully D．In; much more carefully
【答案】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。
24．Mother was always the first one ________ in the morning.
A．get up B．to get up C．gets up D．got up
【答案】B
【详解】句意：在早上的时候，妈妈总是第一个起床的人。
考查动词不定式。get up动词原形；to get up动词不定式；gets up单词第三人称单数形式；
got up动词过去式。the first one to do sth.意为“第一个做某事的人”，空处应填动词不定式。故选B。
25．The line is ________ than that one.
A．more longer B．not longer C．much more longer D．many more longer
【答案】B
【详解】句意：这条线不比那条长。
考查形容词比较级。根据than可知，空处用比较级，long的比较级是longer，more用于构
成多音节词的比较级，而long是单音节词；much用来修饰比较级，可以说much longer，
A、C、D错误。故选B。
26．The earth is ________ the moon.
A．as 49 times big as B．49 times as bigger as C．49 times as big asD．as big as 49 times
【答案】C
【详解】句意：地球是月球的49倍大。
考查as...as的用法。as...as“像……一样”，表示倍数的词放在其前面，中间加形容词或副
词原级，故选C。
27．The book is ________ of the two.
A．thinner B．the thinner C．more thinner D．the thinnest
【答案】B
【详解】句意：这本书是两本中较薄的那本。
考查形容词的比较级。thinner更薄的；the thinner更薄的那个……；more thinner错误表达，
thinner前不用more；the thinnest最薄的那个……。根据“of the two”可知是“两者中
较……”的表达，其构成是“the +比较级+of the two”。故选B。
28．She is the first woman player ________ such a prize.
A．to win B．win C．winning D．won
【答案】A
【详解】句意：她是第一位获得这一奖项的女选手。
考查非谓语动词。根据“the first woman player ... such a prize”可知此处表示“第一个获得这
一奖项的女选手”，用动词不定式to win作后置定语。故选A。

【答案】A【详解】句意：如果你不下定决心克服你的坏习惯，你就无法实现你的目标。
考查动词辨析。achieve实现；win赢得；gain获得；require需要。根据“If you don’t make
up your mind to overcome your bad habits,”可知，应是不克服坏习惯就不能实现目标，
achieve one’s goal“实现目标”。故选A。
二、阅读理解
Some popular places to visit are built by people. Other famous places are created by nature. For
example, in the northeast of the United States, there was a famous rock on a high mountain that
looked just like an old man. He had lots of hair, a big nose and a beard．People called him“The
Old Man of the Mountain” and every year more than a million people came to look at him. “The
Old Man of the Mountain”, also known as the Great Stone Face or the Profile, was 1,200 feet (370
meters) above Profile Lake, and measured 40 feet (12 meters) tall and 25 feet (7.6 meters) wide.
The site is located in the town of Franconia, New Hampshire, USA．Scientists think that the
stone face had been there for about 17,000 years.
In May 2003, there was very bad weather near the Old Man of the Mountain.There were very high
winds and the temperature was very cold. The sky was so cloudy that people couldn’t see the
stone face for many days. As soon as the storm was over, people looked for the Old Man and they
couldn’t see him. They discovered that he had fallen apart. The stones that made his face sank
down the mountain. A number of scientists climbed up to see if they could repair the stone face,
but they had to give up. They figured out（断定）that the damage from the weather was just too
bad.
31．Where’s “The Old Man of the Mountain”?
A．In the northeast of the US. B．In the northwest of the US.
C．In the southeast ofthe US. D．In the southwest of the US.
32．What’s “The Old Man of the Mountain” also known as?
A．The Great Stone． B．The Profile．
C．The Stone Face． D．The Rock．
33．How long had the stone face been there?
A．About 12,000 years. B．About 370 years.
C．About 17,000 years. D．About 25 years.
34．What’s the reason for the loss of the stone face?
A．Low winds. B．Hot temperature.
C．Heavy rain. D．Bad storm.
【答案】
31．A 32．B 33．C 34．D
【导语】
文章讲述了许多名胜古迹中有些是由人创造的，而有些是自然形成的。文章主要讲述了美
国东北部的一块著名的石头在高山上看起来像一个老人，但在暴风雨的侵蚀下消失了。【详解】
31．细节理解题。根据第1段第2句“For example, in the northeast of the United States, there
was a famous rock on a high mountain that looked just like an old man. （比如，在美国的东北
部有一块著名的石头在高山上看起来像一个老人。）”，可知“山中老人”在美国的东北
部，故选A。
32．细节理解题。根据第1段第5句“The Old Man of the Mountain”, also known as the Great
Stone Face or the Profile”可知答案选B。
33．细节理解题。根据第1段最后一句“Scientists think that the stone face had been there for
about 17,000 years. （科学家们认为石头脸有17000年了。）”可知答案选C。
34．细节理解题。根据第2段第4句“As soon as the storm was over, people looked for the
Old Man and they couldn’t see him.（ 风暴一停，人们找不到石像了。）”可知石头面消失
的原因是暴风雨；故答案选D。
