第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项
A
Some young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.
In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.
Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."
His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.
That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.

In the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact（影响）on the environment. After all, you were jumping into your car, driving across town, coughing out emissions（产生排放）and using gas all the way. But now that we're used to staying at home and streaming movies, we might get a littleproud. After all, we're just picking up our phones and maybe turning on the TV. You're welcome. Mother Nature.
Not so fast, says a recent report from the French-based Shift Project. According to "Climate Crisis: The Unsustainable Use of Online Video", digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 1. 6 kilograms of carbon dioxide emissions. That's like driving 6. 28 kilometers. And in the European Union, the Eureca project found that data centers（where videos are stored）there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.
Streaming is only expected to increase as webecome more enamored ofour digital devices（设备）and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world's population will be online.
You're probably not going to give up your streaming services, but there're things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it's also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you're not using your devices.
4. What topic is the first paragraph intended to lead in?
A. The environmental effects of driving private cars.
B. The improvements on environmental awareness.
C. The change in the way people seek entertainment.
D The environmental impacts of screaming services.
5. What does the underlined phrase become more enamored of" in paragraph 3 probably mean?
A. Get more skeptical of.
B. Become more aware of.
C. Feel much crazier about.
D. Get more worried about.
6. What can we infer about the use of streaming services?
A. It is being reduced to protect the planet.
B. Its environmental effects are worsening.
C. It is easily available to almost everyone.
D. Its side effects have drawn global attention.
7. Which of the following is the most environmentally-friendly?
A. Watching downloaded movies on a mobile phone.
B. Downloading music on a personal computer.
C. Uploading a lot of images of the same thing.
D. Playing online games over mobile networks.
C
Salad plants have already been grown in old sheltersand tunnels. Urban farming is a regular topic of interest at places like the World Economic Forum (WEF) in Davos, where leaders consider whether the world's food system, blamed for causing both obesity and malnutrition, can be fixed. There are already plenty of urban farming projects around the world, particularly in the US, Japan and the Netherlands, from urban fish and plant farms to vertical farming.
“It's becoming an expanding industry,” said Richard Ballard, one of the founders of the farm Growing Underground. “There're several other businesses starting up in London in containers, and there are other vertical farms around the country now.”
Growing Underground is not a standard farm. The rows of crops could be in almost any tunnel, but these plants are 100 feet below Clapham High Street and show that urban agriculture is, in some cases at least, nota fad. The underground farm has occupied a part of the Second World War air-raid shelters for nearly five years, and Ballard is planning to expand into the rest of the space later this year.
Growing Underground supplies herb and salad mixes to grocery shops, supermarkets and restaurants. Being
in London creates an advantage, Ballard says, as they can harvest and deliver in an hour.
He adds other advantages. Being underground means temperatures never go below 15℃surface greenhouses need to be heated. They can do more harvests: 60 crops a year, compared with about seven in a traditional farm. Electricity to power the lights is a major cost, but the company believes renewable energy will become cheaper.
Similar British companies include the Jones Food Company in Lincolnshire, while in the US AeroFarms has several projects in New Jersey, and Edenworks in Brooklyn.
8. What do we know about urban farming?
A. It leads to a healthier lifestyle.
B. It is rarely discussed at the WEF.
C. Different farming methods are used.
D. Local governments pay efforts to develop it.
9. Which of the following best explains "a fad" underlined in Paragraph 3?
A. A dream that's easy to realize.
B. A field controlled for a long time.
C. An approach to a serious problem.
D. A fashion that’s popular for a short time.
10. What can we learn about the underground farm?
A. It is more productive than a traditional farm.
B. It provides food directly to the customers.
C. Its major products are herbs and salads.
D. It uses less energy than a greenhouse.
11. What can be a suitable title for the text?
A. Current food system causes health problems
B. Growing Underground attracts more people
C. Traditional farming will be replaced soon
D. Urban farming isstill thought costly and time-consuming
D
When you walk with a backpack, do you know how the things inside move from side to side? Now scientists havefigured out how to tap into that movement to produce electricity.
Picture a pendulum (摆锤) fixed to a backpack frame and stabilized with springs on either side. The pack’s weight is attached to the pendulum, so the pendulum swings side to side as you walk.Then a machine is driven by that swinging movement, and spits out electrical current to charge a battery.
Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O2and CO2. Walking with the slightly swinging 20-pound load, the device (设备) did not significantly affect the volunteers’ metabolic (新陈代谢的) rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of acceleration they’d feel in a regular pack, which might mean
greater comfort for a long hike. And the device did produce a steady trickle (涓流) of electricity. If you up the load to 45 pounds, the swing of the pack could fully charge a smart phone only after 12 hours. The details are in the journal Royal Society Open Science.
The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices. It is particularly useful for those who work in remote areas, as these people often carry a lot of weight in a backpack for their exploration.
But here’s a realconundrum: the energy-harvesting device currently weighs five pounds. The researchers say that’s about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load, to ensure the pack charges you up without weighing you down.
12. What does Paragraph 2 mainly talk about?
A. How the device works.
B. What the device looks like.
C. Who the device is designed for.
D. Why scientists designed the device.
13. Which of the following describes the device?
A. It greatly affected the volunteers metabolic rate.
B. It harvested energy as the volunteers walk.
C. It failed to produce steady electricity.
D. It was useless for a long walk.
14. What does the underlined word “conundrum” in the last paragraph mean?
A. Problem.
B. Method.
C. Bond.
D. Decision.
15. What will the researchers try to do next?
A. Increase the charging speed of their device.
B. Find smarter alternatives to batteries.
C. Reduce the weight of their device.
D. Put their device on the market.
