6．easiest 7．inventors 8．winners 9.awake 10.illness
【详解】
1．句意：迪克决定通过少吃和多做运动来减肥。
本题考查固定短语。短语：lose weight减肥。根据前面的lose是动词后面应该接名词，提示词weigh是动
词“称…重量”，应该用名词重量，故填weight。
2．句意：杰克逊在那么短的时间内解决这个问题有困难。
本题考查固定搭配。have difficultly in doing sth.做某事有困难，根据所给单词solve是动词解决，动名词形
式是solving，故填solving。
3．句意：中国比加拿大拥挤的多。
本题考查形容词比较级。根据后面的than提示可知本题应该是比较级，前面的a lot是多的意思，用于比较
级前，加强语气，more than是比…多，根据常识可知中国要比加拿大拥挤，故填more crowded。
4．句意：教育孩子是一种帮助拯救熊猫的方式。
本题考查动名词做主语。根据提示词teach是动词，动词不能直接做主语，要用动名词的形式，后面的panda是名词前面用动词save，故填Teaching save。
5．句意：现在处于危险中的野生动物需要我们的保护。
本题考查名词。所给词protect是保护的意思，空前面的our是形容词性物主代词，后面要加名词，
protection是名词形式的保护，故填protection。
6．句意：我认为使你强壮的最简单的方法之一就是多锻炼。
本题考查形容词最高级。one of+the+形容词最高级，是“最…之一”的意思，easy的最高级形式是
easiest，故填easiest。
7．句意：爱迪生是世界上最伟大的发明家之一。
本题考查固定搭配。根据常识我们知道爱迪生是发明家，根据提示词invent是动词发明、创造，表示人的
名词是inventor，根据前面的one of后面接可数名词复数，故填inventors。
8．句意：屠呦呦是2015年诺贝尔奖的获得者之一，我们都以她为骄傲。
本题考查固定搭配。根据句子结构one of后面接名词复数，表示…之一，win是动词，名词是winner，名
词复数是winners，故填winners。
9.句意：我进来时婴儿醒着。根据空前的系动词was可知，空处应该用形容词作表语，wake的形容词形式
是awake，意为醒着的。故填awake。
10.句意：他父亲因病看起来很苍老。“his”在本句中是形容词性物主代词，后接名词；“ill”是形容词，表
示“生病的”，其名词形式为“illness 疾病”，故填illness。
二、完成句子，每空一词。
11．这头大象比这只大熊猫重很多倍。
This elephant __________ __________ __________ __________ than this panda.
12．科学家们说现在有不到2,000只大熊猫生活在森林里。

20．因为他正在想事情，没有看路，所以他撞了墙。
As he was thinking and not looking, he ________ ________ a wall.
【答案】
11．weighs many times more 12. fewer than living
13. die of illnesses 14. fewer and fewer cutting down
15. setting up 16. in great danger 17. died from
18. or so 19. are very special to 20. walked into
【详解】
11．本题考查比较级。短语：more than 超过；many times 许多倍。本句是一个陈述事实的句子，用一般
现在时，主语this elephant是第三人称单数，所以weigh重量也用第三人称单数形式weighs，故填weighs
many times more。
12．本题考查比较级以及现在分词。fewer than后面接可数名词，根据2000 pandas是名词复数，是可数名
词所以前面要用fewer than。根据空前面的there are now可知这句话用现在进行时，句中含有there be的现
在进行时，由there+be动词+sth.+动词的现在分词，所以后面的生活live用现在分词living，故填fewer than
living。
13．本题考查固定短语。die of死于…（直接原因），熊猫宝宝死于疾病是直接原因用die of，根据题干可
知本题用的一般现在时，babies是复数，后面的谓语动词要用动词原形，illness是疾病的名词，死于…后
面加名词，故填die of illness。
14．本题考查固定短语。fewer and fewer 越来越少，修饰可数名词复数。cut down砍伐，题干中that从句
中主语是people，根据后面的are可知是人们正在砍树，用进行时，故填fewer and fewer cutting down。
15．本题考查固定短语。短语：set up 建立，根据句意汉语提示可知是正在建立用现在进行时，主语是可
数名词单数，结构是is+动词ing，故填setting up。
16．本题考查固定短语。短语：in danger处于危险中。根据空前面的be动词are可知此处是指一种状态，
处于危险中用固定短语in danger，极度危险在名词danger前加形容词great，故填in great danger。
17.根据中英文对照可知，英文表达中缺少“死于”的英语表达，死于die of/from，在句中作谓语；die of
主要用于指疾病、衰老等自身的原因造成的死亡，die from主要用于指环境、事故等外部原因造成的死亡，根据空后的a traffic accident可知，此处指事故造成的死亡，应该用die from，根据Last month可知本句为
一般过去时，动词应该用过去式died from。故填died；from。
18.根据中英对照，可知这里缺少“大约”这一表达，短语or so，意为“大约”。故填or so。
19.根据中英文对照可知，缺少“对……很特殊”。be special to表示“对……是特别的”，主语为“These
presents”，be动词用are；very“非常，很”，副词，放在形容词前表示程度。故填are；very；special；to。
20.“撞到”可用walk into表示，根据“As he was thinking and not looking”可知，动作发生在过去，应使用
过去式，故填walked；into。
能力提升
一、单项选择
21．He had to be in hospital for some days because of his .
A．illness B．business C．trip D．birthday
【答案】A
【详解】句意：由于生病，他不得不在医院住了几天。

22．________ 30 workers will go to work in that company.
A．Other B．Others C．Another D．The others
【答案】C
【详解】句意：另外30名工人将去那家公司工作。
考查不定代词辨析。Other 其他的，表泛指；Others 其他的，相当于“other+名词”，表泛指；Another 另
外的，表泛指；The others 其他的，相当于“the other+名词”，表特指。由于题干中的30位员工没有特指，
排除D；空格后有名词，排除B；“数词+other+名词复数=another+数词+名词复数”为固定结构，故选
C。
23．In order to help pandas more babies, scientists are doing a lot of research.
A．prepare B．imagine C．produce D．receive

A．falls over B．fell over C．fell off D．falls off
【答案】B
【详解】句意：那个运动员跑得很快，以致于跑的时候摔倒了。

A．each two years B．every two years C．each two year D．every two year
【答案】B
【详解】句意：她的叔叔每两年从美国回来一次，来看望她的祖父母。
考查频度的表达。结合给出四个选项可知，空格处需填“每两年”的表达；英语中表达动作或事情发生的
频率可以用“次数+a+时间计量单位（day/week/month/year...）”或“every+时间单位（two days/two
months/two years...）”，故选B。
27．The clothes in the other store are ______, but ______as those in this store.

阅读单选（2022春·广东·八年级统考期末）
Do you remember the elephant “tour group” in Yunnan? Where are they now? They are back at their home!
In March, 2020, a family of 15 wild Asian elephants left their habitat in Xishuangbanna, Yunnan Province.
Since then, they had kept going north, through mountains, forests, rivers and even city streets. Along their journey,
they ran into villages and ate farmers’ corn. But no one blamed（责怪）them. “It is OK. They are just hungry,” a
farmer said.
Scientists guessed that the elephants were losing their habitat, so they might go north to look for a new home
with more food. Or the group might lose its way because its leader had no experience！
To help the elephants get home and protect them, the government used 76 police cars and trucks, as well as
five diggers and nine drones（无人机）. Police and scientists closely watched them. They watched the group’s
movement and sent warnings（警示）to nearby people not to get close to the elephants. They also helped them
with food and drink. Finally, the elephants ended their trip safely and happily after 17 months and a 500-kilometer
journey.
The Asian elephant is the largest land animal in Asia. Yunnan is the only habitat for wild Asian elephants in
China. The province has built 11 nature reserves. There are only 300 of them in China. The WWF is working hard
to save them.
1．In the article, the underlined word “habitat” means ________.
A．school B．home C．friends D．villagers
2．How many possible reasons for the elephants’ move to the north are there in Paragraph Three?
A．Two. B．Three. C．Four. D．Five.
3．To help the elephants, the government did the following EXCEPT ________.
A．giving them food and drinks B．watching them closely
C．using different machines D．building roads for them
4．Which is TRUE about Asian Elephants?
A．They are dangerous to humans. B．People work hard to protect them.
C．They live in different provinces in China. D．They are the largest animals in the world.
5．Which is the best title for the passage?
A．Welcome Back Home! B．Elephants on the Way!
C．Elephants are Our Friends! D．Protect the Elephants!【答案】
1．B 2．A 3．D 4．B 5．D
【导语】
本文主要讲述了2020年3月份一个由15只野生亚洲象组成的家庭离开了它们在西双版纳的栖息地，去寻
找新的家园，这一路上政府施以援手。云南省已经设立了11个自然保护区，在中国只有300个。世界自然
基金会正在努力拯救它们。
【详解】
1．细节理解题。根据“In March, 2020, a family of 15 wild Asian elephants left their habitat in Xishuangbanna”
及“so they might go north to look for a new home with more food”可知，离开了原本的栖息地，去寻找新的
家园，所以划线单词与home同义，故选B。
2．细节理解题。根据“the elephants were losing their habitat”及“Or the group might lose its way”可知，第三
段一共提到了两点原因，故选A。
3．细节理解题。根据“To help the elephants get home and protect them, the government used 76 police cars and
trucks, as well as five diggers and nine drones（无人机）. Police and scientists closely watched them”及“They
also helped them with food and drink”可知，不包括“为它们建马路”，故选D。
4．推理判断题。根据“The province has built 11 nature reserves…The WWF is working hard to save them”可
知，政府和世界自然基金会都在努力拯救亚洲象，也就是说人们努力来保护它们，B表述正确，故选B。
5．最佳标题题。通读全文可知，本文通过讲述野生亚洲象组团离开栖息地的情况来呼吁人们要保护亚洲
象，所以D选项“保护大象”符合本文标题，故选D。
