2 . Over a four-year period, Swiss researchers have developed a machine that can keep human livers (肝)alive outside of the body for one week.

Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.

The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.

The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.

Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

4 . Young trees don’t just grow; they develop a personality and learn more about their environment and how they should best behave in it. They also help each other out whenever there’s trouble.

Personality, just as among people, varies among trees. Some are anxious, some bold. On the author’s land, there are three oak trees growing close together. One of the oak trees always starts to shed its leaves two weeks earlier than the others. Since they all experience the same temperature, the same soil and the same length of day, such variables can’t be the explanation. So what’s happening? Well, this tree is simply more careful than the others. Whoever holds on to their leaves longer can do more photosynthesis(光合作用) and store more nutrients. However, the longer a tree keeps its leaves, the higher the risk of injury.

Not only do trees make their own decisions, they also learn from their mistakes. A tree, for example, keeping its leaves too long during one year will never make this mistake again. This leads to several other conclusions:trees must notice the temperature and the length of the day and be able to save their experiences somewhere. Obviously, trees don’t have brains, but it is thought that in the sensitive tips of their roots they keep track of information and experiences.

But trees aren’t only clever when it comes to caring for themselves. They also support each other whenever there’s trouble by giving warnings and even taking care of sick and weak conspecifics with nutrients. For example, one time the author found a very old tree stump. Its insides had rotted a long time ago to topsoil. But the wood on the outside of the stump was still living. How was this possible? Well, the stump was nourished by its neighbors with nutrients from the root system, and had been for at least 400 years!

Why do trees do such a thing？It’s simple: it’s better together. Trees need the forest; it protects them from storms, provides the right microclimate and warns them of attacks.

1. Why does the author mention the three oak trees?

A．To illustrate trees can learn from experiences.

B．To show trees can make independent decisions.

C．To explain trees are quite supportive to each other.

D．To prove trees have the same personalities as humans.

2. According to the text, which of the following best describes general features of trees?

A．Anxious and bold.

B．Smart and adventurous.

C．Helpful and well­behaved.

D．Adaptable and supportive.

3. What does the underlined phrase “do such a thing” mean?

A．Give warnings.	B．Offer assistance.
C．Depend on others.	D．Provide nutrients.

4. Where does this text most probably come from?

A．A public lecture.	B．A science book.
C．An experiment report.	D．A travel journal.

5 . Organic food is very popular. It is also expensive. Some organic food costs twice as much as non-organic food, but new parents and pet owners are willing to pay up to 200% more for organic food. However, there are people who think it is a waste of money.

There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals, such as pesticides. In many countries organic foods have special labels. These guarantee that the products are natural.

Some people think organic means locally grown. Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren't enough organic ingredients, such as grain and cattle. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.

Is organic food more nutritious? This is part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals cause health problems such as cancer. Many health professionals disagree. Few studies prove that organic foods prevent health problems. Health specialists worry more about bacteria, such as E.coli and salmonella. These can get into contact with organic and non- organic food. Doctors recommend washing produce very carefully. Handling meat carefully is important too.

Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.

1. What is probably the major concern of organic food consumers?

A．Price.	B．Safety.
C．Freshness.	D．Variety.

2. What is the doctors’ suggestion?

A．Grow your own food.	B．Reduce the use of pesticides.
C．Make sure the food is clean.	D．Buy large companies’ products.

3. Which of the following do most people agree on organic food?

A．It tastes better.	B．It is easier to grow.
C．It contains more fat.	D．It is more nutritious.

4. Where does this text probably come from?

A．A recipe book.	B．A chemistry paper.
C．A medical report.	D．A health magazine.

7 . Pigeons (鸽子) may be considered mice of the sky, but some scientists have found greater value in these urban birds: the blueprint for a new generation of flying machines.

Birds can transform the shape of their wings by fanning out their feathers or moving them closer together. Those adjustments allow birds to cut through the sky more flexibly than rigid drones (无人机). Now, using new insights into exactly how pigeons ‘joints control the spread of their wing feathers, researchers have built a robotic pigeon. This research paves the way for creating more light aircraft, says Dario Floreano, a roboticist in Switzerland not involved in the work.

“What’s really cool about this robot is that you can make adjustments in a robotic wing that you could never do when studying flight in a bird”, says David Lentink, an engineer and biologist at Stanford University. A controllable robotic pigeon solves that problem. In flight tests, Lentink’s team observed that bending only the fingers of one wing eased the robot into a banked turn-offering the first evidence that birds may sometimes use just their fingers to direct in flight. In a second study, Lentink’s group used their robotic wing design to confirm another insight into bird flight: how gaps are prevented from forming between feathers on extended wings.

This is the best set of robotic wings yet for testing how birds adjust their flight feathers to move through the air, says Tyson Hedrick, a biomechanist. But “there’s plenty of room for improvement.” For instance, a future flying robot could include a shoulder joint to investigate how waving a bird’s wings up and down influences flight, he says.

8 . In 1992,Teen Talk Barbie was put on the market with the controversial voice fragment(碎片），＂Math class is hard."While the toy's sale met with strong public reaction,this hidden assumption continues,spreading the belief that women do not boom in science,technology,engineering and mathematic(STEM)fields due to biological inadequacies in math talent.

However,in 2019 Jessica Cantlon at Carnegie Mellon University led a research team that thoroughly examined the brain development of young boys and girls and found no sex difference in brain function or math ability.

Cantlon and her team studied the biological sex differences in math ability of young children.Her team used functional MRI(核磁共振）to measure the brain activity in 104 young children（3-to-10-year-old;55 girls)while watching an educational video covering early math topics,like counting and addition.The researchers compared scans from the boys and girls to evaluate brain similarity.In addition,the team examined brain maturity by comparing the children's scans to those taken from a group of adults(63 adults;25 women)who watched the same math videos.

After many statistical comparisons,Cantlon and her team found no difference in the brain development of girls and boys.In addition,the researchers found no difference in how boys and girls processed math skills while watching the educational videos.Finally,boys' and girls' brain maturity were statistically alike when compared to either men or women in the adult group.

Cantlon said she thinks society and culture are likely directing girls and young women away from math and STEM fields."Typical socialization can make worse small differences between boys and girls that can snowball into how we treat them in science and math,"Cantlon said."We need to be aware of these origins to ensure we aren't the ones causing the sex unfairness."

However,this project is focused on early childhood development using a limited set of math tasks.Cantlon wants to continue this work using a broader scope(范围）of math skills,such as spatial processing and memory,and follow the children over many years.

1. What can we infer after Teen Talk Barbie was on sale?

A．Girls are born with poor math abilities.

B．Math is difficult for both boys and girls.

C．Boys perform no better than girls in math.

D．Math is harder than science and technology.

2. What is the third paragraph mainly about?

A．The result of Cantlon's study.

B．The purpose of Cantlon's job.

C．The method of Cantion's research.

D．The difficulty of Cantlon's work.

3. How will Cantlon further her research?

A．By using a larger variety of subjects.

B．By employing a wider range of math skills.

C．By raising the difficulty of the math tasks.

D．By expanding the number of the children.

4. In which part of a magazine will the text most probably appear?

A．Business.	B．Sports&Health.
C．Entertainment.	D．Popular science.

9 . Australia’s Prime Minister Scott Morrison has expressed regret over his handling of the bushfire crisis damaging the country. The PM has faced mounting criticism over his government’s response to the bushfires and its climate policy.

Since September, bushfires have killed at least 28 people and destroyed thousands of homes. Mr Morrison’s government has been accused of not doing enough to address climate change, which experts say could increase the intensity, frequency and scale of bushfires.

But in the interview, the PM defended his government’s approach, which he said took into account the effect of climate change on the bushfires.

Each year there is a fire season during the Australian summer, with hot, dry weather making it easy for blazes (火焰) to start and spread. Natural causes are to blame most of the time, like lightning strikes in drought-affected forests. Humans can also be to blame. NSW police have charged at least 24 people with deliberately starting bushfires, and have taken legal action against 183 people for fire-related offenses since November, according to a police statement.

Bushfire conditions eased on Saturday, giving firefighters a temporary short break in areas where blazes are still raging. But authorities have warned that the huge fires, spurred by high temperatures, wind and a three-year drought, will persist until there is substantial rainfall.

About half a billion animals have been affected by the fires across NSW, with millions likely dead. The figures for NSW include birds, reptiles, and mammals, except bats. It also excludes insects and frogs, so the real sum is almost certain to be higher, the ecologists said. Almost a third of koalas in NSW may have been killed in the fires, and a third of their habitat has been destroyed, said Federal Environment Minister Sussan Ley.

1. Which of the following statements is true according to the text?

A．The bushfires cause little damage to people’s life in Australia.

B．The PM criticized that his government didn’t take appropriate methods.

C．The PM took active measures to deal with the bushfires damaging the country.

D．Experts say the government’s inadequate action could worsen the bushfires.

2. Which factor has made the huge fires more serious according to authorities?

A．wet weather	B．lightning strike
C．long-lasting drought	D．heavy rainfall

3. What can we infer from the last paragraph?

A．More animals have been affected than the number shows.

B．a billion animals face extinction due to the fires.

C．Koalas are in an immediate danger of dying out.

D．The huge fires have no influence on insects and frogs.

4. Where is the passage probably from?

A．A sci-fi book.	B．A news website.
C．A fashion magazine.	D．A travel journal.

10 . The African grey parrot’s ability to talk and mimic sounds makes it a charming companion. African grey owners often report that their greys oftentimes talk in context and can understand their people’s emotions (情感). The African grey parrot is not just a top talker - this bird is also known for its extreme intelligence, which gives them the name “The Einsteins of the Bird World”.

The bird is medium-sized, dusty-looking and almost pigeon-like. It has a bright red tail, intelligent orange eyes, and a stunning scalloped (扇形的) pattern to its feathers. Their diet in the wild consists mostly of nuts, seeds, fruits, and leafy matter.

At home, African greys need plenty of toys that challenge their intelligence, such as food searching and puzzle toys. Nutri-Berries by Lafeber Company are a perfect choice, which, with a balance of grains, seeds and other nutrients in the shape of a berry, encourages African greys to hold, bite off, and even play with, just as they do in the wild.

African greys seem especially affected by stress and disturbing noise in their environment and can be put more at ease by placing one corner of the cage against a wall as opposed to in the middle of a room.

African grey parrots are more likely to suffer from lack of Vitamin-A/beta-carotene, and therefore benefit from eating vegetables high in beta-carotene, such as cooked sweet potato and fresh kale. Lack of Vitamin-D is another concern, especially for greys on a poor diet. Offering a balanced, pill-shaped diet, such as Nutri-Berries, helps prevent vitamin and mineral shortage.

1. Why are African grey parrots called “The Einsteins of the Bird World”?

A．Because of their brain size.	B．On account of their intelligence.
C．Owing to their rich emotions.	D．Due to their talking ability.

2. What can “Nutri-Berries” probably be?

A．A brand of bird food.	B．Puzzle toys for birds.
C．A type of round fruit.	D．Wild Intelligence games.

3. What is the characteristic of African grey parrots?

A．They may get ill due to lack of Vitamin

B．They prefer to stay in the middle of the room.

C．They are dusty looking with blue eyes.

D．They are smart and love to have fun.

4. Where can we most probably find the passage?

A．In a wildlife magazine.	B．In science fiction.
C．In a travel guide.	D．On a shopping website.
