3 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

When I worked as a nurse, I was on day duty and while my friends were on night duty. On one shift, I remember I sensed something just before going off duty at 11am. I had brought the ward sister her morning tea, so I put down the tea tray. The tray rattled and fell through the window. At first I thought I had accidentally knocked it over, but then I felt the whole building shook and patients screamed.

I realized that we were in the grips of a tremendous earthquake. I caught hold of a nearby patient, who was terribly frightened by it. I pushed her under the bed and held the bed in place while I got under it myself. I then pulled a blanket down between us. As soon as it settled, I decided to try and get the patient safely outside, I carried her out and helped her down to the lawn, where several other people now had gathered.

I knew the ward sister was with another patient, so I went back inside the building. When I reached the ward sister, I found her patient couldn’t walk. We made a seat for her by linking our hands and arms, and carried her outside together. We went back through the building to check no one was left behind. Almost all of the patients had been able to get themselves out of our ward, as far as I knew.

Once our ward was cleared, a doctor called for volunteers to go down to the isolation ward with him to help more people. Another nurse and I went down there. The first thing we saw was a bath in the hallway, We came to the ruined ward. The doctor went in ahead of us through the remains of what had been a doorway. He found one of the nurses partially covered with rubble (碎石). She was still alive so we began to clear the rubble away. Suddenly the aftershock struck. The doctor ordered us to leave. This brave man intended to stay with the trapped nurse and risk his own life.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式，并将答案填写在答题卡上。

Trees provide cool shade and clean air for people     1    (breathe). But would you ever write a letter to a tree? Officials in Melbourne, Australia have discovered that for many the answer is a loud yes. When they carried out a program     2     gave each tree an email address in order to help people identify damage, they     3     (discover) that people preferred to write them love letters instead.

The city is calling it     4     unintended but positive result of their attempt to help people track tree damage. On their urban forest data site, Melbourne assigned (分配) ID numbers and email addresses to each of the city's trees so that it would be     5    (easy) to catch and recover damaged trees than before. Then the emails began to arrive. Instead of some     6    (report) on damage, people began to write fan mail to trees. The writers praised their looks and inner     7    (beautiful). Some told tales of     8     they had helped them survive during bad weather. Some trees even wrote back.

The effort is part of a larger plan. That is to protect Melbourne's 70,000 city-owned trees from reduction and drought. But     9     turns out that Melbournians have always been tree enthusiasts. The government notes that in the 1880s, people wrote asking for     10    (plant) trees to take in bad gases from a nearby factory.

5 . There are nearly 2,800 working satellites in space, which we depend on for technology we use every day, such as video calls, online maps, satellite TV, and weather tracking. Scientists use them to study space and learn more about our planet.

But there are many other satellites in orbit (轨道) that are no longer working. They're among the objects cluttering (使杂乱) up space. Some of these eventually fall back toward Earth, either landing or burning up in the atmosphere. But much of this space junk (垃圾) circles Earth for years. Space junk is a problem. Debris (残骸)   floating around Earth puts technology and future space tasks at risk. Experts are working on ways to solve it.

Orbital debris, a type of space junk, is any human-made object that has slopped working but continues to float around the Earth. This includes satellites that are no longer used and pieces of spacecraft, such as rocket stages. It has been a large problem since the 1960s.

Space junk also includes broken pieces of objects. These occur when satellites hit against things. They also result from an object crashing into an old rocket stage that still contains fuel, causing an explosion (爆炸) . There have been more than 250 space explosions since the 1960s. These tiny broken pieces can damage working satellites, which can affect research in space.

Companies all over the world are working to clean up the area surrounding our planet. A company based in Japan will test the method of using magnets (磁石) to collect space debris. Another mission is led by a company based in Switzerland. It plans to carry out a debris-removal spacecraft in 2025. The craft will get hold of a piece of an old rocket, slow it down, and move it back to Earth. Eventually, the debris will burn out like a shooting star.

Governments are trying to help too. Some are updating their country's space guidelines to limit the amount of debris created. Space is so large that the problem won't be solved by a single organization or a single country. We have to work on this together.

1. What is the biggest harm that space junk does to human beings?

A．It will fall back toward the Earth.	B．It circles the Earth for years.
C．It puts other space objects in danger.	D．It will burn up in the atmosphere.

2. How will the Swiss company clean up the Earth orbit?

A．By making the orbital debris fall back to Earth.	B．By putting the pieces all together.
C．By collecting space junk with magnets.	D．By sending space junk into deep space.

3. What does the author suggest on cleaning up space junk?

A．Strict laws.	B．Global efforts.
C．Stopping in space exploration.	D．Setting up professional organizations.

4. What does the text mainly talk about?

A．Earth and its satellites.	B．The problem of space junk.
C．Ways of cleaning up space junk.	D．The various uses of man-made satellites.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Cities are diverse ecosystems, and a large number of species share our urban areas. As our city spreads, we need think about     1     it is like for other species to have human neighbors.

Because cities     2     (build) for humans, they do not always provide suitable habitats for wildlife. For example, most city parks are kept neat and tidy so that humans will find them     3     (pretty) than before. But when we cut grass or plant flowers, we destroy natural habitats.

When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length of its bottom,     4     made a good home for bats, and soon the bridge was the home of thousands of bats. At first, people were afraid     5     the bats. Now, they have come to value     6     (they) winged neighbors. The bats are a tourist     7     (attract), and they eat lots of bugs every night.

There are also structures built with the objective of     8     (bring) wildlife into the city. The Beijing Olympic Forest Park is a good example. The park     9     (use) native plants and created open, natural spaces for wildlife. The result is a zone where over 160 species of birds can move about     10     (free). If we learn to share our space, we can become better neighbors to the wildlife around us.

7 . Several companies have begun creating paper bottles to replace glass and plastic ones. Paper bottles are easy to recycle, and also weigh less than glass or plastic, meaning they'll require less energy to produce and move around.

A company called Paboco has been working with other companies to develop paper bottles. The companies are creating their own bottle designs, but they're sharing what they learn to promote the development of paper bottle technology

One of the biggest challenges is preventing a paper bottle leaking（泄漏）. The inside of the bottle needs a special coating to make sure the liquid doesn't leak through. Many companies are lining（做衬垫）their bottles with a thin sheet of plastic. Though bottle makers may say this liner can be recycled, many recycling programs don't have the right machines to handle these liners.

A Danish beer company called Carlsberg is working with Paboco on a paper bottle called the "Green Fiber Bottle". Currently the bottle uses a plastic liner. In the future the company hopes to use a "bio-plastic" that will break down naturally over time, And a company named Diageo just announced the first paper bottle whose inside uses a non-plastic coating.

But even without the plastic, paper bottles aren't perfect. Most paper bottles use wood pulp（纸浆）, meaning trees need to be cut down. To solve this problem, Frugalpac, a company from the United Kingdom, has created wine bottles made of recycled paper. Frugalpac still uses a plastic liner, though.

Companies will need to see how long liquids can be stored in the paper bottles and make sure the bottles don't affect the taste. But with so many companies working toward the same goal, it's likely that we can expect to see paper bottles on store shelves in the near future.

1. What is the advantage of paper bottles over other ones?

A．They cost less.	B．They are more appealing.
C．They are easier to produce.	D．They are more eco-friendly.

2. What is the most difficult task to creat paper bottles?

A．Finding recycling liners.

B．Getting the right machine.

C．Preventing the liquid escape.

D．Making sure of the storage time.

3. What does the author think may solve the problem of unperfect paper bottles?

A．Cutting down fewer trees.	B．Using recycled paper.
C．Producing "bio-plastic" liners.	D．Still using plastic liners.

4. What does the author feel about the future of paper bottles?

A．Hopeful.	B．Doubtful.
C．Satisfied.	D．Worried.

8 . Bats are nature's pest hunter. Every night they fly out of their caves to enjoy millions of insects, including some harmful ones. But habitat（栖息地）loss and climate change, as well as infectious diseases are preventing them from doing their job. A new study adds another item to the list wildfires. But not too many—too few.

In California's Sierra Nevada, bats have adapted to occasional fires. But a century of fire-suppression（抑制）policies has kept some areas unburned for long periods, resulting in thicker forests and undergrowth. "We wanted to see how these changes might be influencing bat biodiversity." says ecologist Zack Steel in University of California, who conducted the research.

Steel and his colleagues tracked bats for over four years at six spots in Sierra Nevada. Three of the areas had been recently hit by wildfires, and three remained unburned.

Seventeen bat species call these forests home. The study revealed that eight of them tended to frequent the unburned areas, whereas 11 used the burned areas（some species visited both）. "We expected to see one group of species benefiting from fire—the more open-habitat-adapted species—and another group to be negatively affected by fire and prefer the unburned areas," Steel says. "But even some of those species were occurring more often in burned areas.”

What is ideal, the researchers write, is a combination of unburned areas and ones burned at different levels of severity. The results were published last December in the journal Scientific Reports.

"When there are changes in habitat after a fire, many species benefit in different ways," says University of Connecticut biologist Andrew Stillman. "On the whole, the community becomes more diverse, and that's a good thing for the landscape.”

Extinguishing wildfires early leads to some species losing out on food and resources. "Fire is a natural part of the ecosystem, and many animals require the disturbance from fire to create the types of habitat that they need," Stillman adds. "It shows another negative consequence of keeping wildfire away from fire-adapted forests in California."

1. What can we learn about the research from the text?

A．The researchers kept track of the bats for six years at four spots.

B．11 bat species visited both of the burned and unburned areas.

C．The result of the study was out of the researchers' expectation.

D．The unburned areas were preferred by most of the bat species.

2. What does the underlined word "Extinguishing" mean in the last paragraph?

A．Stopping.	B．Observing.
C．Causing	D．Catching.

3. What is Andrew Stillman's attitude towards wildfires?

A．Negative.	B．Positive.
C．Cautious.	D．Doubtful.

4. Which of the following could be the best title?

A．California Forests	B．Bush Fires
C．Burn Benefits	D．Bats' Habitats

9 . In Ghana, hundreds of schoolchildren are excited to go back to school, on their bamboo bikes. But these hikes aren’t just a green way of getting to classes; they are making a world of difference to students who may have not reached their schools.

Ghana Bamboo Bikes, based in Kumasi in southern Ghana, makes and sells bikes with frames (框架)made from local bamboo. The result is an eco-friendly mix that helps both children and adults avoid a long walk.

Ghana Bamboo Bikes was founded in 2009 by Dapaah and classmate Winnifred Selby after completion of her degree. “When I was in college, I decided to see how best I can do something to give back, especially using our local raw materials,” Dapaah said. Each year, the company donates hundreds of bikes free of charge to kids who face difficulty when going to school.

The project was inspired by Dapaah’s childhood experiences. Raised by her grandfather in a rural village with limited transportation choices, she grew up traveling long distances on foot to get to her school.The company has also created an important source of employment in Kumasi.

Ghana Bamboo Bikes trains and employs men and women as professional craftsmen(手艺人)who harvest the bamboo,shave and sand down the raw materials,assemble(组装)the bikes,and paint them.

This incredible action has grown well over the last decade, with bamboo bikes being purchased by buyers in Europe and the US.And since ten trees are planted with every purchase, the bamboo forests in Ghana are thriving(旺盛的)as well!

1. What is the characteristic of the products of Ghana Bamboo Bikes?

A．They’re free of charge.	B．They’re very fashionable.
C．They’re environment-friendly.	D．They’re intended for adults.

2. What is Winnifred Selby?

A．A professor.	B．A high school student.
C．Dapaah’s manager.	D．A founder of a company.

3. What do we know about Dapaah’s childhood?

A．She led a tough life.	B．She was lacking in love.
C．She was almost starved.	D．She formed the habit of running.

4. What is implied in the last paragraph?

A．Teens in the US love bamboo bikes.

B．Volunteers are badly in need of in Ghana.

C．Sales of bamboo bikes are as important as bamboo forests.

D．The coverage of hamboo bikes is widening beyond Ghana.

10 . 阅读下面材料, 在空白处填入适当的内容（不多于三个单词）或括号内单词的正确形式。

The eruption of hundreds of wildfires across the West of the U.S. is not uncommon as it has become a near-annual occurrence. A massive wildfire forces thousands of people     1     （flee） their homes.     2     （exhaust）firefighters warn of its speed and intensity. Smoke smothers（v. 使窒息）cities and states hundreds of miles away.

Since August 15, 2020 California     3     （witness）900 wildfires, many of which were started by an intense series of lightning strikes. There have been eight fire     4     （death）and more than 3,300 structures destroyed in the flames. The blazes have burned     5     record 2 million acres in California, and the danger for more destruction is so high that the U.S. Forest Service     6     （announce）last Monday it was closing all eight national forests in the southern half of the state.

The fires have spread rapidly during a baking heat wave since mid-August. After a     7     （typical）dry summer, California is heading into     8     normally is the most dangerous time for wildfires when fall comes.

California Oregon and Washington states have seen historic wildfires     9     have burned faster and farther than ever before. Numerous studies in recent years have linked bigger wildfires in the U.S. to global warming, so the real battle is against climate change. Instead of treating the wildfire     10     a threat to be swiftly extinguished, Americans need to learn to live with it, as they have before.
