Being able to tell human faces apart is a skill that almost every person has,although some are far better at it than others.But a new study says that this is not just a skill that humans have. Even fish can do it.

Following up on research studying different species’(物种)abilities to recognize human laces(sheep,dogs,cows,horses,and birds have all been tried),the researchers from the University of Oxford decided to pick an animal that does not have an evolved neocortext,the part of the brain that processes sight and sounds,and doesn’t have a close relationship with humans.That way,there would be no reason why these test subjects(实验对象)would have a past history of identifying human faces.

So they picked the archerfish,a reef fish variety that shoots water into the air to knock its prey(猎物)out of the sky.They used this adaptation to have the fish spray water at a face on a monitor hanging over their tanks for a reward.Most of the fish were able to pick apart their learned face,even when colors were taken away.

This study gives more support to the assumption that distinguishing between faces is not just a skill that big-brained organisms are born with.It is possible that a good percentage of recognizing faces is learned over time.The development of neocortext may contribute only to quickly processing a large number of faces in varying situations.

But more work needs to be conducted to find a deeper link to this possible learned behavior. The sample size of this study was very small-only eight fish were used altogether.Also,the faces displayed were only white,female faces from a German database,shown in a front view, with no expressions.Other animal trials have shown that some species,like pigeons,respond more to different angles and varied expressions.

1.The archerfish were picked as test subjects because they

A.have no evolved neocortext

D.have a past history of recognizing human faces

2.What is the finding of the research?

A.Some animals possess the ability to tell human faces apart.

B.Some animals gain the ability to recognize faces by learning.

C.The fish’s ability to tell human faces apart is a natural skill.

D.The fish’s ability to recognize human faces is related to neocortext.

A.To show more faces in a front view.

B.To display more white,female faces.

C.To test more fish samples to gather more data.

D.To test pigeons’ response to varied expressions.

4.Where is this text most likely from?

A.A diary. B.A biography. C.A mystery. D.A magazine.

Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID-19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing —the NCP’s symptoms are similar to the common cold or the flu, but it’s potentially more dangerous.

Viruses could be deadly, like HIV and Ebola. But what are viruses? How can they cause so much trouble?

Viruses are non-living organisms (有机体) approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.

Viruses can infect every living thing – from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human life. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger no noticeable reaction.

Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.

But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. “Tracing the origins of viruses is difficult”, Ed Rybicki, a virologist (病毒学家) at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils and because of the tricks they use to make copies of themselves within the cells they’ve invaded”.

However, there are three main hypotheses (假说) to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.

For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.

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

A.Viruses have nothing to do with the common cold.

B.Viruses are really small living organisms.

C.Viruses can’t reproduce unless they find a host cell.

D.Viruses enter our bodies mainly through the mouth, nose and hair.

2.Which of the following might explain the origin of viruses?

A.They evolved from the fossils of large organisms.

B.They evolved from parasites into independent organisms.

C.They evolved from the T-cells in animals.

D.They evolved along with their host cells.

3.The underlined word “plausible” in the last paragraph probably means ________.

A.reasonable B.common

C.creative D.unbelievable

4.What can we conclude from the text?

A.Viruses live longer in human host cells than in animals’.

B.Viruses will become more like bacteria as they evolve.

C.It may take a long time to understand the origin of viruses.

D.The author is optimistic about future virus research.

About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?

Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!

Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in tur consumed by larger animals. These food chains are delicately (微妙地) balanced.

The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.

Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most counties have introduced fishing restrictions (限制) to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!

1.From the passage, we learn that _________.

A.most fish and sea animals live at the surface of the seas

B.it is very difficult to break the balance of a food chain

C.over-fishing has caused the decrease in fish stock

D.it won’t be long before the problems concerning oceans will be solved

2.What does the underlined phrase “cope with” mean in Chinse?

A.处理 B.保护 C.增加 D.检验

3.Which of the following is NOT a way being used to protect oceans?

A.The use of international agreements.

B.Forbidding fishing to protect fish socks.

C.The use of new techniques.

D.Raising people’s awareness of the need to protect oceans.

4.What would be the best title of the passage?

A.The Importance of Sea Water

B.Life in the Oceans

C.How to Protect Food Chains

D.How to Deal with Seawater Pollution

A cat with an accent sounds like a character in children’s tale, but Swedish scientists are trying to figure out if domestic cats actually do have different “dialects” based on their geographical location. They also want to understand if the owner’s voice might have a role to play in the way cats’ meow（猫）. If they’re successful, the team of scientists from Lund University. hope to put together a “dictionary” of cat sounds.

The project will be carried out over the next five years. SchÖtz explained that she and her team will use phonetic（语音）analysis to compare cat sounds from two parts of Sweden-Stockholm and Lund-with different human dialects, and figure out if the cats from these regions also have different dialects. They will focus on tune, voice, and speaking style in the human speech that is addressed to cats, and also cat sounds that are addressed to humans.

While it all sounds rather fanciful, the main idea behind the project is to improve the human-cat relationship. Since their domestication（驯化）about 10,000 years ago, cats and humans have learned to “talk” through audio（声音的）and visual signals. Even today, wild cats have no need for meowing in adulthood, while domestic ones continue to meow as a way of communicating with humans. And by understanding more about this communication, SchÖtz and her team hope to influence the way cats are treated in animal hospitals, shelters, and care homes.

The team will record voices of about 30 to 50 cats in different situations, for example when they want access to desired locations, when they are content, friendly, happy, hungry, annoyed, or even angry-and try to identify any differences in their phonetic patterns. They want to know if cats prefer pet-directed speech or prefer to be spoken to like human adults.

The project is yet to begin officially, but the researchers have already started testing their equipment and techniques by recording a few cats’ meowings. And they’ve already made a few interesting observations. In one of the recordings, they noticed that when a cat is begging for food its meows rise slowly. But the opposite happens when the cat is unhappy. By the year 2021, SchÖtz and her team hope to have entirely broken the cats’ code by interpreting all their meowings.

1.Carrying out the research, Swedish Scientists will mainly investigate ______.

A.how cats vary the melody of meows B.how cats communicate with their owners

C.how cats meow with a funny mood D.how cats are treated around the world

2.The main purpose of the project done by Swedish scientists is to ______.

A.find out where the cats live B.understand the cats’ lifestyle

C.build up the human-cat relationship D.make up a dictionary of cat sounds

3.According to the passage it can most probably be inferred that ______.

A.the owners’ voice plays a key role in the way cats meow

B.the research could bring about the cats’ welfare changes in shelters, for instance

C.the owners understand entirely the cats’ need through their meows

D.domestic cats live a happier life than wild ones

4.What attitude does the author hold towards the prospect（前景）of the research？

A.Optimistic. B.Pessimistic.

C.Unconcerned. D.Skeptical.

The values of artistic works, according to cultural relativism(相对主义), are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

History has witnessed the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries, Unique works of this kind are different from today’s popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

In a 1757 essay, the philosopher David Hume argued that because“the general principles of taste are uniform(不变的) in human nature,”the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

1.According to the passage, what do we know about cultural relativism?

A.It introduces different cultural values.

B.It explains the history of artistic works.

C.It relates artistic values to local conditions.

D.It excites the human mind throughout the world.

2.In Paragraph 2, the artists are mentioned in order to show that _____　　 .

A.great works of art can go beyond national boundaries

B.history gives art works special appeal to set them apart

C.popular arts are hardly distinguishable from great arts

D.great artists are skilled at combining various cultures

3.According to Hume, some works of art can exist for centuries because_____　　　 .

A.they are results of scientific study

B.they establish some general principles of art

C.they are created by the world’s greatest artists

D.they appeal to unchanging features of human nature

4.Which of the following can best serve as the title of the passage?

A.Are Artistic Values Universal?

B.Are Popular Arts Permanent?

C.Is Human Nature Uniform?

D.Is Cultural Relativism Scientific?

For a long time, hikers in Japan have considered a bear bell essential. Its tinny ring is said to scare off the huge creatures. Nowadays, however, bear bells are increasingly useful on the way to the shops as well as in the wild. “The number of animals whether bears, boars or monkeys- is expanding, and they are going into villages and towns,” says Hiroto Enari of Yamagata University.

Japan is home to many species of wild animals, including both black and brown bears. It's estimated that the number of bears has been rising since 2000. In 2018, the number was close to 13,000. The reappearance has its roots in human demography (人口统计学): the reduction of Japan's population is especially obvious in rural areas, where it is deeply influenced by ongoing urbanization. Usually, the bears are afraid of entering a village with people around. The appearance of bears is more seen in villages where the population is falling fastest.

Hunting is declining in Japan, too. Government data suggest that the average hunter is now 68 years old. The country's many forests and mountains provide an expansive habitat for wild animals. Indeed, wild areas are growing as foresters and farmers die off. Bears become particularly bold, running into villages for persimmon.

While some welcome the reappearance of bears, others suffer from it. Every year bears injure scores of people, and kill several. Besides, deer can cause damage to farmland. Simple solutions, such as changing the layout around villages or putting up fences, are rarely used. Instead, many bears are caught or killed. In 2013 the government resolved to reduce half the number of certain types of deer, boars and monkeys by 2023. “Japan is struggling to adapt to the changing power balance between animals and people," says Mr. Enari.

1.Why is a bear bell necessary for Japanese hikers?

A.Because it is tinny and convenient.

B.Because it can be used in the wild.

C.Because it can make special noises.

D.Because it can frighten wild animals away.

2.What makes the number of bears increasing so rapidly in Japan?

①Hunting is not as popular as it used to be.

②Bears can enter villages without people's permission.

③Japan' s population in the countryside is falling fast.

④Foresters and farmers are not allowed to kill bears.

A.①④ B.②④ C.①③ D.②③

3.The underlined word “resolved" is closest in meaning to “_________________”.

A.chose B.determined C.managed D.refused

4.What can be inferred from the last paragraph?

A.Japan is trying to balance animals with humans.

B.People are in favour of the reappearance of bears.

C.Changing the layout or putting up fences is useless.

D.The reappearance of bears is harmful to human beings.
