【题目】 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. 【1】 How can they cause so much trouble?
Viruses are non-living organisms 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. 【2】 Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections bring about 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. 【3】 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? 【4】 “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 theories 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.
【5】 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.
A.But what are viruses?
B.For the time being, these are only theories.
C.Once inside, they try to find a host cell to infect.
D.The answer may be even less satisfactory than it now appears.
E.Until now, no clear explanation for their origin exists.
F.Experts are concerned about the bad effect that it had on people’s health.
G.For this reason, they always have the potential to be dangerous to human life.

【题目】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。
It was a peaceful night. I was sleeping with my brothers, feeling warm and comfortable. Mama was sleeping nearby, covered by snow. Papa was somewhere nearby, watching over us. There was a bright moon and we had all had a good meal of venison (鹿肉) Papa had caught earlier.
“Uncle Louis is coming”, Papa said. We loved Uncle Louis. He was a funny wolf, and always had interesting things to tell us and show us.
A little while later, Uncle Louis appeared. We did not approach him with respect the way we approached Papa. We flew at him, jumped all over him, and rolled him in the snow. Uncle Louis laughed and patted us with his paws. He is black all over, with yellow eyes, and he is very tall.
“It's the longest night of the year” , Uncle Louis said, “Does everyone feel like taking a run through the woods? I want to show you something unusual.”
Hearing that, Papa warned that it was dangerous to go near that pack of humans who lived in the woods.
“They are hardly dangerous”, Uncle Louis laughed, “They are so clumsy and make so much noise. They are not able to get near us--or even see us if we don't want them to. Besides, this is their special night. They are quite peaceful and won't be bothering about wolves.”
“Oh, please, Papa, let us run through the woods with Uncle Louis and see something unusual! “ We all begged.
“It is a fine night”, Papa smiled, “I must admit, I do feel like running.”

【题目】 While studying at Jadavpur University, Banerjee wanted to find a creative and socially beneficial alternative to bricks. Along with his classmates, Banerjee created, a social enterprise called Qube in 2017. Its product is the Plastiqube-an alternative brick made from waste plastic.
Banerjee and his team work with waste collectors to gather garbage, including water bottles and abandoned bags. The garbage is then cleaned, cut up and pressed into blocks by hand. “Each Plastiqube brick costs 5 to 6 rupees （about 8 cents） to make，while the average clay brick sells for about 10 rupees (14 cents),” Banerjee says. What 's more, unlike traditional bricks, Plastiqubes don' t use any mortar (砂浆). “They are basically like Lego bricks,” explains Banerjee, now aged 22. He adds，“There are interlocking designs on the bottom and the top, and they lock between each other.
India is estimated to throw away over 25, 000 tons of plastic waste every day. Around 40% of it is left uncollected. “We’re building something sustainable (可持续的) out of garbage,” Banerjee says. By taking coal and mortar out of the brick making process, Banerjee claims Plastiqubes can reduce energy use by 70 percent, generating a much lower carbon foot-print than traditional bricks.
Each Plastiqube brick contains 1.6 kilograms of waste plastic. They haven't yet been tried out for practical purpose but tests on their fire resistance and long- term steadiness are now in progress. Banerjee believes they will last even longer than traditional clay bricks, while removing waste plastic from the environment for centuries.
Banerjee's innovation has, already won him recognition. He was a regional finalist for the United Nation's 2018 Young Champions of the Earth awards. He is also part of the Yunus and Yunus Global Fellowship. Banerjee will not only encourage young engineers to dream big, but also to think carefully about the environmental impact. “My advice is to start something while keeping a goal that it has to be sustainable in the long term,” he says.
【1】Why did Banerjee invent Plastiqube ?
A.To reduce the cost of bricks.B.To protect the environment.
C.To control the usage of mortar.D.To raise his company 's reputation.
【2】Which of the following makes the new bricks join together?
A.Mortar.B.Lego bricks.
C.Average clay.D.Interlocking design.
【3】How does the text describe the characters of Plastiqube?
A.By explaining the process.B.By analyzing some cases.
C.By listing some data.D.By giving examples.
【4】What can we learn from the text?
A.Banerjee has won lots of national awards.
B.Producing Plastiqube needs little labor force.
C.Plastiqube hasn't been used to build houses.
D.Banerjee likes inspiring teenagers to go for dreams.

【题目】 I'm on the phone with a frustrated customer, and a note appears on my computer screen: You are speaking slower than usual. Speed up. I do, and the message disappears, only to be replaced with another: Continuous Speaking — Finish your thought.
This is Cogito, an artificial intelligence program designed to help customer service workers communicate more clearly, empathize (产生共鸣) with frustrated callers, and improve their overall performance. Cogito listens to the tone, pitch, word frequency and other factors in customer service conversations. When it detects something wrong-an irritated customer, a call center agent taking too long to respond — it displays a note on the agent's computer telling them how to improve.
For anyone who's spent hours of their lives stuck on the phone with an unhelpful or very rude customer service agent, Cogito may seem. like a godsend. And some customer service agents using the software generally say they find it helpful. One employee says that Cogito helped her cut her average call time nearly in half, while another says it helped her speaking slow down.
Cogito has been launched to more than sixty call centers across the U. S. over the past year. The company behind the software, Cogito Inc., has raised more than $ 70 million. “We were 45 people a year ago,” says Cogito CEO Josh Feast, whose. company now has 150 employees. At MetLife, managers say that the program improved customer satisfaction by 13%，and helped agents (who take an average of 700 calls a week) to have more “human” conversations.
Such software as Cogito is unlikely to stop at the meeting room. But like other enterprise software, it could soon spread well beyond call centers and other offices and into our daily lives.
【1】What's the purpose of Cogito program?
A.To speed up customer service workers' speaking.
B.To store the conversations between customers and agents.
C.To improve customer service agents' communication with callers.
D.To complain of frustrated callers.
【2】What can we infer about Cogito in Paragraph 4?
A.Cogito bas been used by sixty call centers in the world.
B.The company behind the software benefits a lot from Cogito.
C.Josh Feast designed Cogito with the help of employees.
D.Customers weren't satisfied with MetLife's service without Cogito.
【3】What's the future of Cogito according to the text?
A.It'll be part of our normal day-to-day life.
B.I'll spread into other offices.
C.I'll tell humans what to do.
D.I'll replace customer service agents.
【4】Where is the text most likely from?
A.A novel.B.A brochure.
C.A guidebook.D.A magazine.
