Former truck driver Chen Xianjun played a final chord(和弦) on the guitar as he and his band-mates—a salesperson, a farmer, and two doctors—enjoy themselves in the music. Behind them was the photo of a foreigner wearing a warm smile and hugging his guitar. It was 27-years-old Philip Hancock, an Australian teaching English in Chongqing.
Hancock died in May 2018 in Chongqing because of diabetes. His parents obeyed his wish to donate his organs. Hancock’s liver and kidneys save the lives of three people in the band. And his corneas helped the other two, including Chen see the world again.
“Last year, Red cross officials suggested we form a band in memory of Hancock. They said Hancock loved music and dreamed of having his own band one day,” Chen said, “I’m more than fortunate to be able to do this.”
Over the past year, the five “musicians” have learned different instruments in the studio.
The Band for One, a fitting name for the group, finally came to Hangzhou on Nov.7 to celebrate the 10th anniversary of the implementation(实施) of voluntary organ donations in China.
“I was nervous before stepping on the stage, but I think we did a great job," Chen said. ” All of us now have the ability to carry on with our lives, and I believe that’s exactly what Hancock wanted for us.”
1．How many members are there in the band “The Band for One”
A．Four. B．Five. C．Six. D．Seven.
2．What can we learn from the second paragraph
A．Hancock’s parents disagreed with his wish.
B．Hancock died of liver cancer two years ago.
C．Chen Xianjun lost his eyes when he was born.
D．Hancock’s kindness helped save several lives
3．Why did they choose to form a band
A．They all could play music.
B．It was Hancock’s dream.
C．It was the easiest choice.
D．Red Cross Officials could teach them.
4．When did China begin to carry out the voluntary organ donation
A．In 2010. B．In 2015. C．In 2018. D．In 2020.
5．Which of the following word can best describe Hancock 【版权所有：21教育】
A．Careless. B．Hard-working. C．Kind-hearted. D．Cruel.
参考答案：
本文介绍了五名不同职业的普通 ( http: / / www.21cnjy.com )人，在没有任何音乐基础的情况下，互相配合完成了“一个人的乐队”表演。而之所以称为是“为一个人的乐队”是因为这五名表演者都是一位外国友人的器官受捐者，他们身上有不同的器官来自于这位叫汉考克的澳大利亚小伙子。
1．细节理解题。根据第一段“Former ( http: / / www.21cnjy.com )truck driver Chen Xianjun played a final chord(和弦) on the guitar as he and his band-mates——a salesperson, a farmer, and two doctors——enjoy themselves in the music”可知有卡车司机、一个销售人员，一个农民和两个医生共五个人，故选B。
2．细节理解题。根据第二段“Hancock ( http: / / www.21cnjy.com )died in May 2018 in Chongqing because of diabetes. His parents obeyed his wish to donate his organs...the other two, including Chen see the world again.”可知汉考克的肝脏和肾脏拯救了乐队中三个人的生命。 他的角膜帮助了另外两个人，包括陈再次看到世界。所以，汉考克的义举帮助挽救了几条生命，故选D。
3．细节理解题。根据第三 ( http: / / www.21cnjy.com )段“Last year, Red cross officials suggested we form a band in memory of Hancock. They said Hancock loved music and dreamed of having his own band one day,” Chen said,”可知是因为汉考克爱音乐，并希望有一支自己的乐队，故选B。
4．细节理解题。根据第五段“ ( http: / / www.21cnjy.com )The Band for One, a fitting name for the group, finally came to Hangzhou on Nov.7 to celebrate the 10th anniversary of the implementation(实施) of voluntary organ donations in China.”可知终于在11月7日来到杭州，以庆祝在中国实施自愿器官捐赠10周年；根据时间倒推10年，所以中国实施自愿器官捐是2010年，故选A。
5．推理判断题。根据第二段“Hanco ( http: / / www.21cnjy.com )ck died in May 2018 in Chongqing because of diabetes. His parents obeyed his wish to donate his organs. ”可知首先是汉考克自愿捐赠器官去拯救其他人，所以可推知他是一个善良的人，去世后都想着帮助别人，故选C。
（B）
There was a story ( http: / / www.21cnjy.com )many years ago of a school teacher—Mrs.Thompson.She told the children on the first day that she loved them all the same.But that was a lie.There in the front row was a little boy named Teddy Stoddard.He didn’t play well with the other children and he always needed a bath.She did not like him.
Then Mrs.Tho ( http: / / www.21cnjy.com )mpson got to know that Teddy was actually a very good boy before the death of his mother.Mrs.Thompson was ashamed (羞耻) of herself.She felt even worse when,like all her other students,Teddy brought her a Christmas present too.It was his mother’s perfume(香水).

Isn’t fast food delic ( http: / / www.21cnjy.com )ious Aren’t fast food restaurants cool ... The answer to these questions is yes.
However, there are ( http: / / www.21cnjy.com ) growing facts that fast food is one of the worst parts of modern life. And studies have shown that burgers and fried chicken, which we enjoy so much, can cause a lot of health problems.
In spite of (尽管)this ( http: / / www.21cnjy.com ), why are fast food restaurants so attractive(吸引人的) The first and most important reason is that their service is fast. Their staff(员工) are friendly and very smart-looking in their clean and bright uniforms(制服). Moreover, most fast food restaurants are near places that people always pass by. It is so easy to grab a burger and eat on the way to work.
Fast food is often ( http: / / www.21cnjy.com ) so conveniently packed(包装方便) that it will not cause a mess even if you stand and eat it. Fast food restaurants are also very clean. A lot of clever ads(广告) have made them the coolest places in town, but none of them has ever told and will never tell you that too much fast food is not good for your health.
Such attractive p ( http: / / www.21cnjy.com )laces are selling junk food! Isn’t it a pity Is there a way to change the fast food restaurants into special places where you get the best possible, healthy and fresh food
Well, why not
As people real ( http: / / www.21cnjy.com )ize the health problems that fast food causes, it is quite likely that fast food restaurants may go out of date. It may happen sooner or later. 21教育网
Therefore, instead of ( http: / / www.21cnjy.com ) resisting(抵制) fast food restaurants, a better idea may be to persuade(说服) them to change their menu! Fast food restaurants can be places to go to when you want to eat something that will be good for your body. If they could combine(结合) healthy food with their speed of service, delicious tastes and comfortable feelings, that will be the next best thing on the earth for the human beings!

本文是一篇议论文。文章指出人们知道快餐 ( http: / / www.21cnjy.com )会导致一些健康问题，但是快餐店以其美味的食品、快速的服务、干净明亮的制服等吸引着顾客。文章又指出如果快餐店改变菜单，把健康的食物和服务速度、美味和给人的舒适感受结合起来，它将会变成地球上的另一个好地方。
1. D 解析：代词指代题。联系上段中 ( http: / / www.21cnjy.com )的“And studies have shown that burgers and fried chicken, which we enjoy so much, can cause a lot of health problems.”可知，此处指我们喜欢的汉堡和炸鸡能导致许多健康问题，而汉堡和炸鸡属于快餐，所以，this指代“Fast food can cause health problems.”。
2. D 解析：细节理解题。短文前四段 ( http: / / www.21cnjy.com )中出现过快餐的美味、快捷等内容。第四段最后一句“..., but none of them has ever told and will never tell you that too much fast food is not good for your health.”告诉我们快餐对我们健康不利，它不包括在快餐的优点中。故选D。
3. B 解析：词义猜 ( http: / / www.21cnjy.com )测题。结合上句“Moreover, most fast food restaurants are near places that people always pass by.”以及后面的“eat on the way to work”可知，快餐很容易拿到。故选B。
4. B 解析：推理判断题。由第 ( http: / / www.21cnjy.com )四段中“A lot of clever ads(广告) have made them the coolest places in town, but none of them has ever told and will never tell you that too much fast food is not good for your health.”，可知广告从没告诉你也决不会告诉你，吃太多的快餐会对健康不利，由此推知“快餐广告不会告诉大家所有的真相”。
5. D 解析：推理判断题 ( http: / / www.21cnjy.com )。由最后一段，特别是最后一句“If they could combine(结合) healthy food with their speed of service, delicious tastes and comfortable feelings, that will be the next best thing on the earth for the human beings!”可推知，作者建议制作对健康有益的快餐。

Part of Eart ( http: / / www.21cnjy.com )h’s beauty comes from its oceans.Ocean scientists study the chemical make-up of the ocean,weather patterns,the geography of the ocean floor,and many other areas.Their work is exciting,although sometimes dangerous.Using technology to do certain tasks helps.For example,robotic arms are used for very dangerous tasks.
One basic part of ( http: / / www.21cnjy.com ) ocean study is understanding waves and how they work.Wind is the great maker of waves.The waves we know are mostly produced by winds blowing over the sea.They are directly connected with the wind speed and the time that wind lasts.
Sometimes ocean l ( http: / / www.21cnjy.com )ife can be seen in the wave.Living things seem to be staying within the wave,moving slowly inside it as if they were weightless. Besides the beauty of waves,scientists are interested in their technical ways.The diagram of waves shows how scientists examine waves.Waves are measured(测量) from the top (crest) to the bottom (trough).This allows scientists to find out the height of a wave.They also measure waves from crest to crest to determine (测定) the length of a wave.21*cnjy*com
During serious sto ( http: / / www.21cnjy.com )rms,huge waves might cut a sea ship apart.Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave.By understanding the ocean,scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships.The study of waves and the ocean also allows scientists to make sure how certain beaches were formed.By studying the oceans,a great deal can be learned about the surface we live on.
1.Why are robotic arms used Because .
A.certain tasks are very dangerous
B.the tasks are exciting
C.the oceans are beautiful
D.there are many studying areas
2.What can we learn from the second paragraph
A.Waves can make wind.
B.Most waves are produced by winds.
C.Scientists make most waves.
D.Waves have nothing to do with wind.
3.What is th ( http: / / www.21cnjy.com )e meaning of “the length of a wave” according to Paragraph 3
A.The beauty of huge waves.
B.The technical way to study the sea.
C.The distance from crest to crest of a wave.
D.The distance from the top to the bottom of a wave.21世纪教育网版权所有
4.Where is the passage probably from
A.A diary entry. B.A fairy tale.
C.A travel guide. D.A science magazine.21教育名师原创作品

We see humans ( http: / / www.21cnjy.com ) all around us. But when was the first human seen Early humans did not leave behind any written records. However, they left behind many paintings on the walls of the caves(洞穴) where they lived. These paintings tell about their life, and we know these early humans walked on four limbs(四肢) like apes（猿）. Also, they did not live at one place but moved from place to place in search of food and water. 21cnjy.com
Without any tools, e ( http: / / www.21cnjy.com )arly humans used stones, bones of animals, and sharp pieces of wood to dig, hunt and cut their food. They also used these to protect themselves from animals. Since stones were used to make tools, this age was called Stone Age.
With time going ( http: / / www.21cnjy.com ), tools made of bones and stones were replaced with metal(金属的) ones which were stronger, sharper, and long-lasting. Metals were also used for farming and making knives. Copper(铜) was the first metal to be used. www-2-1-cnjy-com
The first fire t ( http: / / www.21cnjy.com )hat early humans noticed was natural fire caused by lightning(闪电). With fire, early humans could now light up dark caves. They could keep themselves warm during cold weather and cook meat. Also the fire could drive animals away.
Early humans noticed n ( http: / / www.21cnjy.com )ew trees growing from the seeds(种子) that fell to the ground from the fruits. This gave them the idea that they could make their own food by planting seeds, which led to farming. With the beginning of farming, early humans began to settle down(定居). They moved out of the caves and lived on farms and near their fields together, then the first villages came up.
Raising animals was a ( http: / / www.21cnjy.com )big event in human history that changed the life of early humans. The wild dogs were probably the first animal to be raised. As time went, goats, sheep, cows, donkeys, and horses were kept, too. This led to herding(畜牧业). Milk, meat and wool came from these animals.
1.Early humans’ paintings don’t tell us _____.
A. when the first human appeared B. how they walked
C. where they lived D. how they lived
2. Early humans had to move around in order to ____.
A. find more cav ( http: / / www.21cnjy.com )es to live in B. protect themselves from animals
C. look for food and water D. make kinds of tools
3. Early humans used fire to ______.
① light up dark caves ② keep themselves warm ③ cook meat
④ drive animals away ⑤ make knives
A. ①②③④ B. ①②④⑤ C. ②③④⑤ D. ①②③⑤
4. Early humans were able to live in one place when _______.
A. they could walk on two feet B. they could use metals
C. they knew how to farm D. they knew how to use fire
5. Which statement is right according to the passage
A. The first tools were made of copper.
B. The first fire noticed by early humans was caused by lightning.
C. The first villages came up before the farming appeared.
D. The first animal to be raised was sheep.
参考答案：
这是一篇说明文。文章主要介绍了早期的人类生活及人类生活的演变过程。
1. A 解析：细节理解题。根据第一段中 ( http: / / www.21cnjy.com )的“These paintings tell about their life, and we know these early humans walked on four limbs(四肢) like apes（猿）. Also, they did not live at one place but moved from place to place in search of food and water.” 可知，通过原始人留在洞穴墙壁上的画可知，他们生活在洞穴中，用四肢行走，不定居而是到处迁徙。但我们不能从画中知道人类最早是从什么时候出现的。故选A。
2.C 解析：细节理解题。根据第一段中 ( http: / / www.21cnjy.com )的“…they did not live at one place but moved from place to place in search of food and water.”可知，他们到处迁徙是为了寻找食物和水。故选C。
3. A 解析：细节理 ( http: / / www.21cnjy.com )解题。根据第四段中的“With fire, early humans could now light up dark caves. They could keep themselves warm during cold weather and cook meat. Also the fire could drive animals away.”可知，原始人利用火可以照亮黑暗的洞穴，用火取暖、煮肉，驱赶动物。故选A。www.21-cn-jy.com
4. C 解析：推理 ( http: / / www.21cnjy.com )判断题。根据第五段中的“With the beginning of farming, early humans began to settle down.”(随着农业的开始，早期的人类开始安定下来。)可推知，原始人开始过定居生活是他们懂得了农耕生活以后，故选C。
5. B 解析：推理判断 ( http: / / www.21cnjy.com )题。根据第三段中的“With time going, tools made of bones and stones were replaced with metal(金属的) ones which were stronger, sharper, and long-lasting.”（随着时间的推移，由骨头和石头制成的工具被金属所取代，这些金属更坚固、更锋利、更持久。）可知，最早的工具不是金属的；根据第四段中的“The first fire that early humans noticed was natural fire caused by lightning”(早期人类注意到的第一场火灾是由闪电引起的自然火灾)；根据第五段中的“With the beginning of farming, early humans began to settle down(定居). They moved out of the caves and lived on farms and near their fields together, then the first villages came up.”可知，人类开始过定居生活是在农耕之后，而不是之前；根据最后一段中的“The wild dogs were probably the first animal to be raised.”可知，最早驯养的野生动物是狗而不是羊。故选B。

Once there were ( http: / / www.21cnjy.com ) many thousands of Gourma Desert (沙漠) elephants in Mali,a country in West Africa.Now,there are fewer than four hundred.21·cn·jy·com
Why did the ( http: / / www.21cnjy.com )number of the elephants drop so quickly On the one hand,the elephants’ main lake,their only water source (来源),dried up.On the other hand,the land which the elephants lived on was overused by humans.
To protect th ( http: / / www.21cnjy.com )e elephants’ living environment,the Mali Elephant Project (MEP) was started in 2007.MEP met with local people and helped them make rules of using land and water.As a result,the situation became better and there was more food,forest and grassland.
However,from 2012 to ( http: / / www.21cnjy.com )2016,poaching (偷猎) and illegal trade in the elephants increased rapidly.Eighty-three elephants were lost in 2015 alone,and another fifty-one elephant were killed in 2016.“If this situation goes on,all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily,the voi ( http: / / www.21cnjy.com )ce of MEP was heard.More organizations (组织) have joined together to educate the local people that trading elephants is against the law.Elephant poaching has dropped to a very low level.The local people have learned to live peacefully with the elephants,one of the wildlife treasures in the world.

Scientists say they ( http: / / www.21cnjy.com )’ve developed a new system(系统). It can use “machine learning” to predict when and where lightning(闪电) will strike(闪击). The research was led by engineers from Switzerland.
European resea ( http: / / www.21cnjy.com )rchers have estimated(估算) between 6, 000 and 24,000 people are killed by lightning worldwide each year. The strikes can also cause power cuts, destroy houses and start forest fires. For these reasons, some climate scientists have studied to develop methods to predict and control lightning. But no system has been created to effectively predict lightning.
The new system ( http: / / www.21cnjy.com ) is being tested in the experiments(实验). It used a combination of data(数据资料) from weather stations and machine learning methods. The researchers developed a prediction model. It was trained to tell weather conditions that were possible to cause lightning.
The model was cr ( http: / / www.21cnjy.com )eated with some data. The data was collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data related to(与……有关) four main surface conditions: air pressure, air temperature, relative humidity(相对湿度) and wind speed.
The atmospheric(大气的) d ( http: / / www.21cnjy.com )ata was put into a machine learning algorithm(计算程序), which compared it to records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning happens.
Amirhossein Mostaj ( http: / / www.21cnjy.com )abi is a PhD student who led the development of the new system. He said, “Common systems for collecting such data are slow and complex, and they require expensive collection equipment(设备) like radar or satellites (卫星).”
“Our system uses d ( http: / / www.21cnjy.com )ata that can be gotten from any weather station,” Mostajabi said. “This will improve data collection in the areas which are not covered by radar and satellites or in places where communication systems have been cut,” he added.

If your pencil b ( http: / / www.21cnjy.com )ox is broken, the batteries (电池) in your flashlights run out, or you have some leftover food, how will you deal with these things You will probably throw them all into one rubbish bin. But actually, we need to sort (分类) all the rubbish separately. If you don’t sort your rubbish, all of it will go to a special place where it is buried (埋藏) together. As a result, it will take up some fields. Some rubbish will pollute the groundwater. Some rubbish that can be reused will be wasted.
In recent ye ( http: / / www.21cnjy.com )ars, some Chinese cities have been working hard on rubbish sorting.
Shanghai has called on ( http: / / www.21cnjy.com ) all the people living in this city to sort their rubbish into four groups: wet, recyclable, harmful and dry. Wet waste is known as household waste. They are things you don’t want but pigs can eat. Paper, metal, glass, plastic and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries. Finally, any waste that is not wet, recyclable or harmful will go to the “dry waste” bin.
Many other Chinese ci ( http: / / www.21cnjy.com )ties are also using this way to sort their rubbish. For example, Deyang has been sorting its rubbish into the same four groups since several years ago. Students in Deyang have already received waste-sorting guidebooks. They have studied these books and known how to sort the rubbish.
China is now ( http: / / www.21cnjy.com )improving its waste-sorting efforts. There is still a long way to go. But it's never too late to learn how to -sort your rubbish rightly. We should take an active part in it.
1. How many ( http: / / www.21cnjy.com )bad results will there be if all the rubbish is buried together
A. Two. B. Three. C. Four. D. Five.
2. What does the underlined phrase “take up” in Paragraph 1 mean
A. 处理 B. 改变 C. 占用 D. 从事
3. Which of the following is harmful waste
A. Metal. B. Paper. C. Medicine. D. Glass.
4. What can we learn from the passage
A. Students in Deyang have known how to sort the rubbish.
B. Paper and metal can be thrown into a “dry waste” bin.
C. The whole world is working hard on rubbish sorting.
D. China has already succeeded in sorting the rubbish.

Isn’t fast food d ( http: / / www.21cnjy.com )elicious Aren’t fast food restaurants cool ... The answer to these questions is yes.
However, the ( http: / / www.21cnjy.com )re are growing facts that fast food is one of the worst parts of modern life. And studies have shown that burgers and fried chicken, which we enjoy so much, can cause a lot of health problems.
In spite of (尽管 ( http: / / www.21cnjy.com ))this, why are fast food restaurants so attractive(吸引人的) The first and most important reason is that their service is fast. Their staff(员工) are friendly and very smart-looking in their clean and bright uniforms(制服). Moreover, most fast food restaurants are near places that people always pass by. It is so easy to grab a burger and eat on the way to work.
Fast food is ofte ( http: / / www.21cnjy.com )n so conveniently packed(包装方便) that it will not cause a mess even if you stand and eat it. Fast food restaurants are also very clean. A lot of clever ads(广告) have made them the coolest places in town, but none of them has ever told and will never tell you that too much fast food is not good for your health.
Such attractive places ( http: / / www.21cnjy.com ) are selling junk food! Isn’t it a pity Is there a way to change the fast food restaurants into special places where you get the best possible, healthy and fresh food
Well, why not
As people realize the ( http: / / www.21cnjy.com ) health problems that fast food causes, it is quite likely that fast food restaurants may go out of date. It may happen sooner or later.
Therefore, instead of ( http: / / www.21cnjy.com )resisting(抵制) fast food restaurants, a better idea may be to persuade(说服) them to change their menu! Fast food restaurants can be places to go to when you want to eat something that will be good for your body. If they could combine(结合) healthy food with their speed of service, delicious tastes and comfortable feelings, that will be the next best thing on the earth for the human beings! 21cnjy.com
1. What does “this” in Paragraph 2 refer to
A. Fast food is ( http: / / www.21cnjy.com )delicious. B. Fast food restaurants are cool.

Part of Earth’s beauty ( http: / / www.21cnjy.com ) comes from its oceans.Ocean scientists study the chemical make-up of the ocean,weather patterns,the geography of the ocean floor,and many other areas.Their work is exciting,although sometimes dangerous.Using technology to do certain tasks helps.For example,robotic arms are used for very dangerous tasks.
One basic part of ( http: / / www.21cnjy.com ) ocean study is understanding waves and how they work.Wind is the great maker of waves.The waves we know are mostly produced by winds blowing over the sea.They are directly connected with the wind speed and the time that wind lasts.
Sometimes ocean life ( http: / / www.21cnjy.com ) can be seen in the wave.Living things seem to be staying within the wave,moving slowly inside it as if they were weightless. Besides the beauty of waves,scientists are interested in their technical ways.The diagram of waves shows how scientists examine waves.Waves are measured(测量) from the top (crest) to the bottom (trough).This allows scientists to find out the height of a wave.They also measure waves from crest to crest to determine (测定) the length of a wave.
During serious storm ( http: / / www.21cnjy.com )s,huge waves might cut a sea ship apart.Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave.By understanding the ocean,scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships.The study of waves and the ocean also allows scientists to make sure how certain beaches were formed.By studying the oceans,a great deal can be learned about the surface we live on.
1.Why are robotic arms used Because .
A.certain tasks are very dangerous
B.the tasks are exciting
C.the oceans are beautiful

When Shanghai introdu ( http: / / www.21cnjy.com )ced a new garbage-sorting policy (垃圾分类政策) in July last year,the city’s residents (居民) took some time to get used to it.They joked that every time they took out their garbage,the staff (工作人员) standing by the bins would ask,“What kind of garbage are you ”【来源：21cnj*y.co*m】
Starting on May 1 ( http: / / www.21cnjy.com ),Beijing joined many Chinese cities by introducing a new garbage-sorting policy,People’s Daily reported.Residents should sort their garbage into four groups:kitchen,recyclable,hazardous (有害的) and other waste.
These groups are repre ( http: / / www.21cnjy.com )sented (代表) by four different colors of trash bins—green,blue,red and gray.Those who fail to sort their trash correctly may be fined (被罚款) up to 200 yuan,Xinhua reported.
Some cities like Shan ( http: / / www.21cnjy.com )ghai and Qingdao sort their trash differently.These cities use four different groups:wet,recyclable,harmful and dry.Although their names are different,the groups are actually the same.In fact,wet garbage in Shanghai is kitchen garbage in Beijing.And dry garbage is the same as other waste,China Youth Daily reported.
To help residents sort ( http: / / www.21cnjy.com ) their trash correctly,the Beijing government is offering online guidelines.If people don’t know how to throw away garbage,they can search for it on the WeChat account Guanchenglishi(管城理市) to find out.But searching a key word or taking a photo,people can immediately find out which group their waste belongs to.

We see humans all a ( http: / / www.21cnjy.com )round us. But when was the first human seen Early humans did not leave behind any written records. However, they left behind many paintings on the walls of the caves(洞穴) where they lived. These paintings tell about their life, and we know these early humans walked on four limbs(四肢) like apes（猿）. Also, they did not live at one place but moved from place to place in search of food and water. 21教育名师原创作品
Without any tools, e ( http: / / www.21cnjy.com )arly humans used stones, bones of animals, and sharp pieces of wood to dig, hunt and cut their food. They also used these to protect themselves from animals. Since stones were used to make tools, this age was called Stone Age.
With time going, to ( http: / / www.21cnjy.com )ols made of bones and stones were replaced with metal(金属的) ones which were stronger, sharper, and long-lasting. Metals were also used for farming and making knives. Copper(铜) was the first metal to be used.
The first fi ( http: / / www.21cnjy.com )re that early humans noticed was natural fire caused by lightning(闪电). With fire, early humans could now light up dark caves. They could keep themselves warm during cold weather and cook meat. Also the fire could drive animals away.www.21-cn-jy.com
Early humans noti ( http: / / www.21cnjy.com )ced new trees growing from the seeds(种子) that fell to the ground from the fruits. This gave them the idea that they could make their own food by planting seeds, which led to farming. With the beginning of farming, early humans began to settle down(定居). They moved out of the caves and lived on farms and near their fields together, then the first villages came up.
Raising animals was a ( http: / / www.21cnjy.com )big event in human history that changed the life of early humans. The wild dogs were probably the first animal to be raised. As time went, goats, sheep, cows, donkeys, and horses were kept, too. This led to herding(畜牧业). Milk, meat and wool came from these animals.
1.Early humans’ paintings don’t tell us _____.
A. when the first human appeared B. how they walked
C. where they lived D. how they lived
2. Early humans had to move around in order to ____.
A. find more c ( http: / / www.21cnjy.com )aves to live in B. protect themselves from animals
C. look for food and water D. make kinds of tools
3. Early humans used fire to ______.
① light up dark caves ② keep themselves warm ③ cook meat
④ drive animals away ⑤ make knives
A. ①②③④ B. ①②④⑤ C. ②③④⑤ D. ①②③⑤
4. Early humans were able to live in one place when _______.
A. they could walk on two feet B. they could use metals
C. they knew how to farm D. they knew how to use fire
5. Which statement is right according to the passage
A. The first tools were made of copper.
B. The first fire noticed by early humans was caused by lightning.

Once there wer ( http: / / www.21cnjy.com )e many thousands of Gourma Desert (沙漠) elephants in Mali,a country in West Africa.Now,there are fewer than four hundred.
Why did the num ( http: / / www.21cnjy.com )ber of the elephants drop so quickly On the one hand,the elephants’ main lake,their only water source (来源),dried up.On the other hand,the land which the elephants lived on was overused by humans.
To protect the el ( http: / / www.21cnjy.com )ephants’ living environment,the Mali Elephant Project (MEP) was started in 2007.MEP met with local people and helped them make rules of using land and water.As a result,the situation became better and there was more food,forest and grassland.
However,from 20 ( http: / / www.21cnjy.com )12 to 2016,poaching (偷猎) and illegal trade in the elephants increased rapidly.Eighty-three elephants were lost in 2015 alone,and another fifty-one elephant were killed in 2016.“If this situation goes on,all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily,the voice of ( http: / / www.21cnjy.com ) MEP was heard.More organizations (组织) have joined together to educate the local people that trading elephants is against the law.Elephant poaching has dropped to a very low level.The local people have learned to live peacefully with the elephants,one of the wildlife treasures in the world.21*cnjy*com
