21、 We think of winter as cold and flu season，but the cold temperatures have powerful biological upsides too.
Boosts your brain
【1】 .Studies have found that people perform some cognitive（认知的）tasks like making decisions better when the temperature is cooler. Research has also shown that people are less willing to handle complex tasks in the summer than in the winter.
Burns calories（卡路里）
When it's cold，your body works harder to keep your core temperature，which is typically. about 98.6 degrees. "Our bodies use a considerable amount of energy to keep us warm and to dampen the air we breathe when we're out in the cold，"explains Stacy Tucker，an expert from Kansas City. 【2】 . A recent study showed that participants burned 34 percent more calories when they hiked in 14-to 23-degree temperatures than they did hiking on 50-degree days.
Activates healthy fat
We know accumulating too much ordinary fat or "white fat" can endanger our health. But adults also have small amounts of beneficial "brown fat" that can quicken their metabolism（新陈代谢）and bum more calories 【3】 .
Encourages better sleep
Your body's core temperature drops when you're trying to sleep. 【4】，but it's much faster in winter，says Tucker. Plus，with darker mornings，you naturally sleep later.
【5】
Yes，you might get more colds during the winter. However，studies have shown that the immune system can be activated by colder temperatures，which improves our ability to fight infections，explains Tucker. That said，the flu virus becomes strong in cold，dry air，and time spent indoors increases your chance of infection. To reduce risk，get your annual flu shot，wash your hands frequently，and go outside.
A. Fights infections
B. So fasten your boots
C. Suffers from infections
D. Colder temperatures can help you think more clearly
E. And cold temperatures can activate this useful fat
F. Exercising in the winter makes heart muscles stronger
G. This process can take up to two hours in the summer
22、Peter and Minke van Wingerden have created something wild: a herd of cows floating on the sea. The Dutch husband-and-wife team’s experiment on sustainable agriculture, called Floating Farm, can be found in the port of Rotterdam. The modernist structure houses 40 cows, who collectively produce some 200 gallons of milk a day. In addition to helping nourish (滋养) the local community, the waterborne farm is playing a part in the global conversation about how the climate crisis is pushing farmers to reconsider how—and where—they produce food.
Floods, extreme heating, droughts and even rising night temperatures have sent the food system off balance. The race to outsmart the constant attack of extreme weather has made the world of farming unrecognizable from what it was only decades ago. A team of scientists in Mexico is developing wheat types that can adapt themselves to different climates, while Jack’s Solar Garden in Longmont, Colorado, is a testbed for the emerging method of solar farming.
Rotterdam has already established itself as one of the most climate-adaptive places in the world. Everything from office buildings to entire neighborhoods are built on water in the city, which is 90% below sea level. The Wingerdens’ Floating Farm was a new but necessary attempt. Should a weather crisis arise, a waterborne farm isn’t necessarily stuck in place. A former property developer with a background in engineering, Peter found his inspiration for the Floating Farm in a climate disaster in New York City, where Hurricane Sandy prevented the delivery of fresh food to millions.
The Wingerdens’ model is ripe for reproduction—which is exactly what the Floating Farm’s team of 14 are working on now. Plans are under way for a floating vegetable farm to move into the space next to the current Floating Farm. Permit applications are also out for similar structures in Dubai, Singapore and the Dutch cities of Haarlem and Arnhem.
The new projects will apply lessons learned from Floating Farm. “You need to build a house in order to know how to build a house,” Peter says. The biggest obstacles he sees ahead, however, are not financial or physical, but rather political and administrative. “One of the biggest challenges we come across worldwide is regulations. Cities need to have disruptive thinking, cities need to have disruptive departments, and cities need to have areas where you can say: OK, this is the experimental zone.” Because what Peter and his team are pulling off is of a different order than the typical sustainability measures. “We are not innovative,” he says. “We are disruptive.”
【1】Which of the following is TRUE about the Floating Farm?
A．It is the first modern farming attempt to fight climate change.
B．It is a model of new agriculture in the age of climate crisis.
C．It has outsmarted other forms of farming like solar farming.

【2】It can be inferred from the passage that ___________.
A．90% of the population in Rotterdam live below the sea level
B．The New York City is working hard to fight climate change
C．The local community will not be fed without new farming
D．Waterborne facilities are necessary to the future of Rotterdam
【3】The phrase “disruptive thinking” in the last paragraph means “thinking __________”.
A．in a daring and unusual way
B．in a focused and logical way
C．in a careful and detailed way
D．in a rude and unpleasant way
【4】Which of the following might be the best title of the passage?
A．Is Rotterdam Built on Water?
B．Can Floating Farming Survive?
C．Are Cows at Sea the Future of Farming?
D．Is Extreme Weather Affecting Agriculture?
23、One of the astronomy's most well-known telescopes-the 305-metre-wide radio telescope at Arecibo, Puerto Rico-is closing forever. Engineers cannot find a safe way to repair it after two cables supporting the structure suddenly and catastrophically broke, one in August and one in early November.
The Arecibo telescope, which was built in 1963, was the world's largest radio telescope for decades and has historical and modern importance in astronomy. It was the site from which astronomers sent an interstellar radio message in 1974, in case any extraterrestrial might hear it, and where the first known extrasolar planet was discovered, in 1992. It has also done groundbreaking work in detecting near-Earth planets, observing the puzzling celestial blasts known as fast radio bursts, and studying many other phenomena.
The cables that broke helped support a 900-tonne platform of scientific instruments, which hangs above the main telescope dish. The first cable broke panels at the edge of the dish, but the second tore huge gashes in a central portion of it. If any more cables fail-which could happen at any time-the entire platform could crash into the dish below. The US National Science Foundation(NSF), which owns the Arecibo Observatory, is working on plans to safely lower the platform down in a controlled fashion.
NSF's officials insist that the cable failures came as a surprise. After the first, engineering teams spotted a handful of broken wires on the second cable, which was more crucial to holding up the structure, but they did not see it as a major problem because the weight it was carrying was well within its design capacity.
Some of the observatory's scientific projects may be able to be transferred to other facilities, said Ralph Gaume, the NSF's head of astronomy. And he expects scientists to suggest where to shift their research. Science does continue at other portions of the Arecibo Observatory, which includes more than the 305-metre-dish. They include two lidar facilities that shoot lasers into the atmosphere to study atmospheric phenomena.
【1】What is Paragraph 2 mainly about?
A．The history of building the telescope.
B．The key role of the telescope in astronomy.
C．The benefit of learning astronomical events.
D．The process of locating near-Earth planets.
【2】According to Paragraph 3, we know that________.
A．NSF's officials tried to repair the platform
B．the second cable failure destroyed the platform
C．the scientific instruments broke down due to the cables
D．the platform would not break down if no more cables should fail
【3】Why were NSF's officials careless about the broken wires on the second cable?
A．The cable was not very old.
B．The wires were specially designed.
C．The weight the cable bore did not go beyond its limit.
D．The cable was not as important as the first one.
【4】What will happen to the ongoing scientific projects at the observatory?
A．All of them will be shut down.
B．Some of them will be moved to other facilities.
C．They will be distributed to different scientists.
D．Some of them will be put off.
24、 China successfully sent the 52nd and 53rd satellites of its domestically developed BeiDou Navigation Satellite System (BDS)—the last two medium Earth orbit (MEO) satellites for the BDS-3 constellation (星座)—into space on Monday, marking the completion of the global navigation system’s core constellation deployment (部署) and this year’s BDS satellite launch campaign.
Launched from Xichang Satellite Launch Center, Sichuan Province, on board a Long March-3B carrier rocket with an Expedition-1 upper stage, the two satellites were injected into planned orbits after more than three hours’ flight.
Since the first BDS-3 satellite was launched on November 5, 2017, China has conducted 18 BDS satellite launch missions, successfully sending 30 into their planned orbit, setting a national record for highest mission frequency and success rate.
In-orbit tests will be carried out before the two MEO satellites are commissioned (正式委托). By then the core constellation for the Chinese global navigation satellite system will be successfully completed.
Wang Ping, chief designer of the BDS-3 system, said that the hybrid constellation design, in which three groups of satellites—the Inclined Geo Synchronous Orbit (IGSO), MEO and geosynchronous Earth orbit (GEO)—work in concert in different orbits, was an exclusive BDS innovation and a world first. “Existing global navigation satellite systems, such as the US GPS and Russia’s GLONASS, only have a MEO satellite constellation,” said Wang.
The MEO satellites, in orbit 20,000 kilometers above Earth, are a special type of satellite providing global service, while the IGSO and GEO satellites, in an orbit 360,000 kilometers above Earth, mainly enhance regional service quality, according to Wang. That explained why completion of the MEO constellation was significant, marking the completion of the core network for BDS-3, meaning a stable BDS-3 global coverage without weak points has been carried out.
Feedback shows that the BDS service quality was already comparable to GPS since the end of 2018, and after completing BDS-3, “We will be as good as any GNSS.” Wang said.
【1】How many BDS satellites were sent into their planned orbit successfully?
A．3.
B．18.
C．30.
D．36.
【2】What’s the advantage of BDS compared with GPS and GLONASS?
A．The diverse functions.
B．The excellent service quality.
C．The lower cost of designing it.
D．The ability to work in different orbits.
【3】Why are the MEO satellites important?
A．They enhance regional service quality.
B．They can be put into use immediately.
C．They can enter farther orbits.
D．They can serve the world.
【4】What may be the best title for the text?
A．China Becomes the First Country to Launch a MEO Satellite
B．The Core Constellation of BDS-3 Completes Deployment
C．The BDS-3 System Has Benefited Many Countries
D．Exploring Space Is Very Important to the World

26、Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
The production of fine art is the use of skill and imagination to create aesthetic objects or experiences which can be shared with other people. Photography is thought by some to be a form of fine art; however, others claim that photography is not.
Those who believe that photography is not a form of art present several arguments. They claim a photograph is nothing but an objective record of a particular place at a particular time. Therefore, any beauty that is perceived in the picture is the beauty of the time and place where it was taken, and is not the creation of the photographer. They also argue that sophisticated and expensive equipment often plays a greater role in the success of a photograph than the photographer’s creativity. Even some of the greatest photographers acknowledge that there is a limit to the amount of influence they can have on a final product.
However, there are also many reasons why photography is appreciated on the same level as other recognized forms of visual art. The decisions involved in creating a photograph are analogous to those made by any other artist. A photograph is not just a banal record of the world, but a deliberately created image with its own artistic features. Ansel Adams, the American photographer, commented on this point when he noted: ‘You don’t take a photograph, you make it.’ There is a growing trend for photographers to call themselves artists and their photos are sold for millions of dollars. However, these high prices may not be enough to change people’s perceptions of whether photography is art.
The arguments about whether photography is art have been discussed since the earliest cameras were used. The creative process involved in taking a fine photograph, deciding what, when and how the picture should be taken, is certainly similar to the process of making fine art. However, cameras are also increasingly used to take photographs for non-artistic functions. Although we cannot say that photography itself is necessarily art, we can certainly see that it is a medium that can be used to make art.
