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、 Sonoma County is adding artificial intelligence to its wildfire fighting. The county has entered into an agreement with the South Korean firm Alchera to equip its network of fire-spotting cameras with software that detects wildfire activity and then issues a warning to authorities.
The technology examines past and current images of terrain (地形;地势) and searches for certain changes, such as flames burning in darkness, said Chris Godley, the county’s director of emergency management. But emergency workers will first have to“teach”the system to distinguish between images that show fire smoke, and others that might show clouds, fog etc. The software will use feedback from humans to improve its algorithm(算法) and will eventually be able to detect fires on its own — or at least that’s what county officials hope.
“It’s kind of like learning how to read,” Godley said. “What letters can I put together to make up a word?” The county activated the technology Wednesday and received 16 positive reports of smoke — all of which turned out to be permitted burns, he said. Once a seasonal ban on controlled burns goes into effect in April or May, the county plans to speed up the testing and feedback phase. The hope is that by November, the system will no longer need to be taught and can start providing reliable intelligence. Godley said. “It’s going to take us a while to make sure we get the bugs out and that we really can depend on it because ultimately this is a lifesaving mission.”
The technology is intended to help officials investigate potential fire starts earlier so they can get personnel out to them more quickly and issue necessary warnings. Officials expect other places will adopt it if the technology is successful, particularly because it plugs into the camera network that’s already in place statewide.
“We ultimately believe its potential could be realized in a year or two,” Godley said. “And it could really have a dramatic impact here in California.”
【1】What does the system first have to do before being put into work?

B．AI is applied to monitor terrains in California.
C．A new tool to help detect wildfire in California.
D．A new way to put an end to wildfire in California.
23、The invention of the 1D barcodes revolutionized supermarkets and general market management. But shortly after their introduction, their disadvantages were clear. There was an instant demand to be able to encode (编码) more than 20 alphanumeric characters (字符) that the traditional barcodes could hold.
Denso Wave, a Japanese company, at the time, was in the business of manufacturing 1D barcode scanners. Listening to feedback from users of the 1D barcode scanners they were selling, they put together a development team to come up with a solution.
One of the key targets was to ensure that no matter what barcode they designed, it can be scanned very fast. It took the team nearly 18 months, and eventually they came up with a barcode that could hold up to 7,000 alphanumerical characters and could be scanned up to 10 times faster than any other code at the time. In 1994, the QR Code was born.
The QR Code quickly spread outside of Japan and were approved for many standards globally. But that wasn’t the end of the development of the QR Code. After all, nothing is perfect at its beginning and people soon began to present more requirements to Denso Wave. The variations (变体) of the QR Code were soon developed.
One of the biggest reasons why the QR Code has been able to be used widely is that Denso Wave made the decision to make the QR Code publicly available. This means anyone can use it without paying any fees. Denso Wave do hold a patent for the QR Code, but have declared that they have no intention to exercise it.
It wasn’t until 2002 that the first smartphones came to market with the QR Code scanner, and this really accelerated the technology. Once widespread on phones, almost anyone can read these codes and doesn’t require expensive hardware to do so. It is believed that Nokia is the first to bring this technology to a mobile device.

24、As new year approaches, crowds around the world may be expecting fireworks to light up the sky. But the fireworks could finally lose their appeal with the growing use of drones (无人机) for light shows. One obvious example was drone light show in the opening ceremony of Tokyo Olympics.
Ollie Howitt, a technician at SkyMagic, which used 300 drones to create a display for London’s new year celebration, said demand had increased substantially. She added that drones were increasingly able to fly in greater density and for longer. Howitt also said there were benefits of drones, “They give out no pollutants, they’re reusable, and there’s no fallout or that kind of thing. So in that sense they are a very sensible choice.”
Robert Neff, the general manager at Mercia Harbor, also said the decision to use a drone display at the harbor was down to a number of factors, including the impact of fireworks on animals — from wildlife to the pets of boat owners. “They’ve often commented on how much suffering is caused to their pets by the fireworks,” he said.
But not everyone agrees. Hans Rosling, a spokesperson from the British Fireworks Association said drones could also pose environmental problems. “Suggestions are that drones have less of an impact on the environment, but we have concerns about electrical demand and use of lithium (锂) batteries which are known not to be all that ‘green’,” he said. “The impact of firework use on the environment has been shown to be minor and very short-lived and recent studies have suggested that there is likely to be more pollution from a couple of cars driving to an event than caused by fireworks at an event.”
And there are issues with drone light displays, which need to receive specific safety approval from certain authorities. Some suggest the use of drones doesn’t mean shutting off fireworks. The bangs of fireworks create a sound feeling that is hard to replace. Meanwhile, others prefer the chance to tell stories in the sky by using a series of image.
【1】Why does the writer talk about the Tokyo Olympics in Para 1?
A．To attract readers’ attention to the Olympics.
B．To advocate setting off fireworks in the new year.
C．To introduce the popular use of drones for light shows.

26、阅读下面短文，然后按要求写一篇150词左右的英语短文。
Big or small, rejection affects us all. Harry Potter was rejected. So was The Twilight Saga. If authors J. K. Rowling and Stephenie Meyer hadn’t kept trying with publisher after publisher, we’d all have missed out on some great adventures.
Rejection doesn’t have to be about the big thing like not getting into your top college, not making the team, or not getting asked to the prom (舞会). Everyday situations can lead to the feeling of rejection, too, like if your joke doesn’t get a laugh, if no one remembers to save you a seat at the lunch table, or if the person you really like talks to everyone but you.
Feeling rejected is the opposite of feeling accepted. But being rejected (and we will all be at times) doesn’t mean someone isn’t liked, valued, or important. It just means that one time, in one situation, with one person, things didn’t work out.
Rejection hurts. But it’s impossible to avoid it altogether. In fact, you don’t want to — people who become too afraid of rejection might hold back from going after something they want. Sure, they avoid rejection, but they’re also 100% guaranteed to miss out on what they want but won’t try for.
