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
Buildings can become greener. They can use more recycled steel and can be built in off-site factories，greatly reducing lorry journeys. But no other building material has environmental credentials（认证）as exciting and overlooked as wood.
The energy required to produce a laminated（复合的）wooden beam is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing，wooden buildings contribute to negative emissions by storing the stuff. When a mature tree is cut down，a new one can be planted to replace it，capturing more carbon. After buildings are pulled down，old beams and panels are easy to recycle into new structures. And for improving older buildings to be more energy efficient，wood is a good insulator（绝缘体），A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium one.
A race is on to build the world's tallest fully wooden skyscraper. But such buildings are still uncommon. Industry disunity，cut-throat competition for contracts and low profit margins（差额）mean that most building firms have little money for greener construction methods beyond what regulation requires
Governments can help urge the industry to use more wood，particularly in the public section. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be changed to take account of the emissions that exist in materials. This would favour wood as well as novel ways of producing other materials.
Construction codes could be adjusted to make building with wood easier. Here the direction of travel is wrong. Britain，for instance，is banning the use of wood on the outside of tall buildings after 72 people died in a tower fire in London in 2017.That is a nonsense. Grenfell Tower was covered in aluminium and plastic，not wood. Modern cross-laminated wood panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world's buildings into line.

D.The environmental costs of buildings rely on carpentry.
An international team of astronomers in Washington D.C. announced Wednesday it had success fully captured the first-ever image of a black hole and published it.
The picture shows the black hole having a dark center，encircled by a bright orange and yellow ring spreading outward. Black holes are areas in space where gravity is so strong that nothing-not even light-can escape them. They are believed to be formed by collapsed（陨落的）stars. The presence of black holes affects the surrounding environment in extreme ways. They are not easy to capture on camera because they are surrounded by thick dust material and extremely hot gases.
But scientists say they were able to produce the new image from data collected from a series of radio telescopes around the world. Harvard University scientist Sheperd Doeleman，who leads the Event Horizon Telescope（EHT）project，announced the image discovery. "We are delighted to be able to report today that we have seen what we thought was unseeable. We have also taken a picture of it." He explained that the image resulted from a combined effort involving all eight of the EHT radio telescopes working at the same time. It has a mass 6.5 billion times greater than Earth's sun.
Researchers said that the EHT project created an Earth-sized "virtual（虚拟的）telescope" to capture the highest possible image quality. The size and shape of the shadow matches the precise Predictions of Einstein's general theory of relativity.
Sheperd Doeleman said the new image provides the first visual evidence to confirm that theory. It also helps to unlock the mystery of black holes. "We didn't see something that was unexpected. We saw something that really had a ring to it. "
Even though the data was first gathered in 2017, it required a huge effort to produce the image published on Wednesday.
1.Which is True about the black hole?
A.It has a dark surface.
B.It consists of thick dust.
C.It is visible to the eye
D.It swallows everything approaching it.
2.What does the underlined word "They" in Paragraph 2 refer to?
A.Black holes.
B.Collapsed stars.
C.Extreme ways.
D.Hot gases.
3.How did scientists get the image?
A.By collecting available data.
B.Through the cooperation of radio telescopes.
C.With the help of a huge camera.
D.From Einstein's general theory of relativity.
4.What does the image discovery contribute to?
A.Uncovering the secret of black holes.
B.Confirming people's wisdom.
C.Testing the function of virtual telescopes.
D.Providing first-hand evidence for astronomers.
Ed Jackson："I want to be the first quadriplegic（四肢瘫痪者）to climb Everest，"
Former Wasps player was told he would never walk again after an accident in 2017.
"It was a lovely day like this and we had a barbecue." Ed Jackson says as he remembers the accident which broke his neck，ended his rugby career and left him paralyzed（瘫痪）with a medical prediction that he would never walk again. "I walked to the edge of a feature pool with a waterfall at one end. I couldn't tell which was the deep end so I dived in，fell straight to the bottom，and hit the top of my head. When I tried to stand up I couldn't. Luckily my dad was in the pool. He's a retired doctor and he knew it was a spinal cord（脊柱）issue."
Jackson survived surgery but was told that his paralysis was almost certainly permanent. "After five days of trying to move my toes with nothing happening，I thought there's a good chance they're right."
"Every night on my own，I imagined what it would be like for my wife to look after me for the rest of my life. If this was going to continue all my life，I would never have forgiven myself." In the dark，his mind was at war with itself. "That fear of the unknown is terrifying. Every day I would stare at my toe and try to move it."
On day six his toe twitched（抽动）！The next few months became a series of his exciting moments. Jackson kept chasing those wins.
Once Jackson could walk he decided to climb Snowdon to coincide with the first anniversary of the accident. On 1 April 2018，with a heavy brace on his leg，Jackson reached the summit of Snowdon.
Climbing is exhausting and dangerous for a quadriplegic but，with his face lit by sunshine，Jackson uncovers a previously secret dream. "I want to be the first quadriplegic to climb Everest. I would love that to be where the story of my recovery ends. And then I just want to go on laughing and living.
1.What was Jackson doing when the accident happened？
A.Barbecuing. B.Swimming.
C.Playing rugby. D.Diving.
2.What do we know about Jackson?
A.He was able to walk six days later.
B.Doctors' prediction had no effect on him.
C.The accident left him deadly injured.
D.He climbed Snowdon to repay his family's concern.
3.What might be the main drive for Jackson to get better?
A.His father's first aid. B.The successful surgery.
C.His affection for his wife. D.His desire to climb.
4.What can be a suitable title for the text?
