21、 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 (症状) are similar to the common cold or the flu, but it’s potentially more dangerous.
Viruses could be deadly, like HIV and Ebola (埃博拉). 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 (入侵) 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 (引起) 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 at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils (化石) 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 reasonable 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.

22、 Artificial flesh is growing ever closer to the real thing. Scientists in Australia have now created a new jelly-like material which they claim has the strength and lasting usage of actual skin, ligaments(韧带）,or even bone.
“With the special chemistry we’ve engineered in the hydrogel(水凝胶）,it can repair itself after it has been broken like human skin can,” explains chemist Luke Connal from the Australian National University. “Hydrogels are usually weak, but our material is so strong it could easily lift very heavy objects and can change its shape like human muscles do.”
Having a wet and soft material with such remarkable properties could be very important for the development of next-generation soft robotics and biomedical devices. Creating a shape-changing hydrogel that has multiple functions has proved an ongoing challenge for scientists, even with natural inspiration from sea creatures, such as jellyfish, sea cucumbers, and Venus fly traps.
While some hydrogels can withstand mechanical stress, others have self-healing properties, and a few more have the abilities to memorize shapes or change colours. As far as the ANU researchers know, no one else has been able to incorporate all these functions into one all-encompassing gel. At least, not at the speed and efficiency they’ve achieved.
Using this material, the researchers made extremely thin films of “flesh” without any breakage.
When these films were heated or cooled, they then changed into different shapes, bending one way or the other before returning back to their original state along with the temperature. If temperature is somehow used as a control, the authors think this gel could one day be moved like an artificial muscle. Researchers are trying to modify their temperature control technology accordingly and make a significant step towards turning this hydrogel into practical use.
【1】What do you know about the new material according to the text?
A.It looks like the jelly and functions like the robot.
B.It can be easily repaired by scientists after being broken.
C.It is likely to be the most multifunctional hydrogel at present.
D.It can hardly go back to its original shape after heated or cooled.
【2】What is the author’s attitude towards the future of the dynamic hydrogel?
A.Indifferent.
B.Neutral.
C.Negative.
D.Positive.
【3】What is the best title for the text?
A.Getting scientific inspiration from nature.
B.Lifting heavy objects by dynamic hydrogels.
C.Creating a new kind of flesh with chemistry.
D.Enabling artificial robots to heal themselves.
【4】What will the author most probably talk about in the following paragraph?
A.The characters of artificial flesh.
B.The creation of the dynamic hydrogel.
C.The shapes and colors of artificial flesh.
D.The application of the dynamic hydrogel.
23、After ruling the tennis world for almost five years,Roger Federer is adjusting to life at NO.2.But,like any king whose throne has been taken away,the Swiss star is already planning secretly bis return to power,beginning at this week's US Open.
The problem is,many experts think he will never do it.They blame everything from age and tough competition to his racket and psychology.
For years Federer,had enjoyed the view from the top.Competitors saw him as undefeated,and for the most part he was.However,before the 2008 season began,Federer had an illness that stole his strength and clearly affected his play on the court.Ever since,he has struggled to return to form,winning just two of his last 14 tournaments.
"Twenty-seven is an age when your body starts talking back to you."tennis great John McEnroe told the New York Times.
Pancho Sefura,another tennis great,noted that Federer is also facing a maturing crop of young talents."There are too many great players now,"he said,naming Britain's Andy Murray,21,and Latvia's Ernests Gulbis,20.
US magazine Sports Illustrated tennis columnist Jon Wertheim suggested that part of Federer's problem could be his insistence on using a small racket.He says that the smaller head demands ball control.But we see time and again that racket makers try to get players to use a certain stick-one they would like to market to consumers and it has a negative effect on the professional game.
Sports psychologist Jim Loehr told the Times that Federer is probably feeling "a sense of doubt"after being considered as undefeated for so long.If Federer is to recover his state of being undefeated,Loehr said he must overcome his doubt."Federer doesn't need fame and money.But he has to get better.He has to go t.o a whole new level.That's the only way he stays in the game,"he said.
As for beginning his first Grand Slam in ages as the NO.2 seed,Federer said it might be for the best."Five years almost,I was expected to win every tournament I entered,"he said,"so maybe Rafael Nadal now feels what I had to feel for a very long time.It will be interesting to see how he handles it."
【1】What does the underlined part "your body starts talking back to you" in Para.4 mean?
A. Your body often argues with you.
B. You can do whatever you want.
C. Your strength is beginning to decline.
D. You are more easily to have quite terrible diseases.
【2】From the passage,we know the main reason why Federer's throne was taken away is that .
A. he is becoming older and older
B. he insisted on using a small racket
C. he is facing a maturing crop of young talents
D. he had an illness that stole his strength
【3】What can be inferred from the passage?
A. Now it is Nadal who has replaced Federer as the No.1 tennis player.
B. the racket makers aim at the players' better performance in games.
C. It is impossible for Federer to return to power.
D. Federer has never won a Grand Slam before.
【4】What's the best title of the passage?
A. Nadal—The No.1 Tennis Player
B. Federer—Always Undefeated
C. State of Mind Plays a Important Role
D. Federer Hopes to Recover His Magic
24、The summer is so hot and sticky, why would we want to sweat even more by exercising? Or is it just I who think like that? Sweat and clothes sticking to our bodies as we move make exercise seem rather uncomfortable. What can be done to fix it?
Researchers at MIT have come up with a solution. They’ve developed a workout suit with flaps that open as the wearer begins sweating. As the person cools off, the flaps shrink until they assume their original position.
Sounds cool, sounds practical. These flaps are lined with live, microbial ( 微生物的)cells. These cells can detect when the body is heating up too much, and in response, expand. It’s just as if they were working within any other organism, recognizing patterns of heating and cooling, then responding appropriately to maintain body temperature. It seems kind of strange to have living cells (that aren’t your own) on you, right? Not to fear, these cells have been believed safe. Plus, there’s a material in the suit that helps the flaps/cells hover ever so slightly above the exerciser's skin. The flaps start opening as soon as people start feeling warm and sweaty, and the bit of space between the suit and the skin helps develop that feeling of cool and refreshing air as they move. For more information about flaps, click here.
According to Gadgetify.com, researchers have also been working to apply this technology to running shoes as well. Moisture-responsive workout clothing has the potential to revolutionize sport fashion industry. People can stay drier, cooler and fresher at the end of the workout, which sounds better than leaving the gym with a trail of sweat and a red face. It’s possible that the comfort of these suits can make people enjoy exercising more and exercise with more intensity.
【1】What’s the purpose of the first paragraph?
A．To introduce the topic.
B．To show his dislike of summer.
C．To give an example.
D．To tell of his dream.
【2】What can’t be learned from the passage?
A．When a person doesn’t sweat, the flaps will come to its original position.
B．The flaps themselves can float slightly around the exerciser’s skin.
C．When a person sweats, the flaps will expand.
D．The flaps are essential to cooling exercisers down.
【3】What’s mainly talked about in the last paragraph?
A．The influence of the technology.
B．The efficiency of the technology.
C．Different reviews on the technology.
D．Author’s attitude to the technology.
【4】Where does the essay come from?

25、Face shape lets AI spot rare disorders
People with genetic syndromes（综合征）sometimes have revealing facial features, but using them to make a quick and cheap diagnosis can be_____ given there are hundreds of possible conditions they may have. A new neural network that analyses photographs of faces can help doctors _____ the possibilities.
Yaron Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the overall impression of faces and _____ a list of the 10 genetic syndromes a person is most likely to have.
They _____ the neural network, called DeepGestalt, on 17,000 images correctly labelled to match more than 200 genetic syndromes. The team then asked the AI to _____ potential genetic disorders from a further 502 photos of people with such conditions. It included the correct answer among its list of 10 responses 91 per cent of the time.
Gurovich and his team also_____ the neural network’s ability to distinguish between the different genetic mutations (变异) that can lead to the same syndrome. They used photographs of people with Noonan syndrome, which can result from mutations in any one of five genes. DeepGestalt correctly identified the genetic source of the physical appearance 64 per cent of the time. It’s clearly not _____, but it’s still much better than humans are at trying to do this.
As the system makes its assessments, the facial regions that were most helpful in the determination are _____ and made available for doctors to view. This helps them to understand the relationships between genetic make-up and physical appearance.
The fact that the diagnosis is based on a simple photograph raises questions about_____. If faces can reveal details about genetics, then employers and insurance providers could, in principle, _____ use such techniques to _____ against people who have a high probability of having certain disorders. _____, Gurovich says the tool will only be _____ for use by clinicians.
This technique could bring significant_____ for those who have genetic syndromes. The real value here is that for some of these ultra-rare diseases, the process of diagnosis can be many, many years. This kind of technology can help narrow down the search space and then be confirmed through checking genetic markers. For some diseases, it will cut down the time to diagnosis dramatically. For others, it could perhaps add means of finding other people with the disease and, _____, help find new treatments or cures.
【1】A.convincing B.tricky C.reliable D.feasible
【2】A.bring about B.result from C.narrow down D.rule out
