21、 Sleep plays an important part in repairing the body and keeping us healthy, but with all of the demands of modem living, getting a good night's sleep can be a challenge. Using electronic products such as computers and smartphones has been considered to disturb sleep because of the blue light given off by their LED displays. Yet, new research has shown that screen time alone may not be as harmful as we thought before.
Scientists at the University of Manchester measured the impact of colored light on the sleep patterns of mice to learn more about how different colors act on the body. They said that twilight (暮色) could provide a physical signal to tell you when to sleep. So, using brighter, warmer lights in the day and cooler lights in the evening could be better for people's health.
“Melanopsin (黑视蛋白) makes people easily feel the difference of brightness. Researchers try to change the impacts of light on sleep by adjusting the brightness signals identified by melanopsin,” said Dr Tim Brown, a senior lecturer at the School of Medical Sciences and one of the study's authors. So not being exposed to blue light and staring at your electronic products for a long time could really help adjust your sleep.”
However, reducing brightness may be more helpful than simply controlling the amount of blue light. And blue light remover that warms up the screens of computers or smartphones by increasing yellow light could actually be harmful to sleep. Harvard Medical School links exposure (接触) to blue light at night to cancer and heart disease. The health warnings about blue light run deeper than disturbed sleep. Though sunlight is the main source of blue light, the way we stare at computers and smartphones for long periods gives cause for concern.
【1】Why did scientists conduct the research according to Paragraph 2?
A.To know people's screen using habits.
B.To test the effects of electronic products on sleep patterns.
C.To find out the influence of colored light on physical health.
D.To change people’s negative feelings toward colored light.
【2】What is the main feature of melanopsin?
A.It avoids lots of harm to our eyes.
B.It provides the most suitable light.
C.It makes people see things clearly.
D.It presents information of brightness changes.
【3】What can be inferred from the last paragraph?
A.More blue light at night harms people’s skin.
B.Sunlight provides people with helpful blue light.
C.Using yellow light on the screen could protect people’s eyes.
D.Turning down screen brightness before sleep can reduce health risks.
【4】In which section of a newspaper may this text appear?
A.Health.
B.Business.
C.Technology.
D.Entertainment.
22、 The final bell rings at a high school in downtown Los Angeles. Nearly every student walking out of the school gate studies a screen, with their head bowed down. Over the past decade, such scenes have become quite common — at least in the United Sates. Research indicates that American millennials look at their phones 150 times a day on average.
In the meantime, the number of American teenagers reporting feelings of depression has grown significantly. Some people blame the increase on the Great Recession following 2008 and other social changes. However, a big new study suggests a different explanation —the rise of social media. Jean Twenge, a psychology professor at San Diego State University, led the study.
With data collected from more than 50,000 American teenagers, she found that those who spent lots of time on social media were more likely to agree with remarks such as “The future often seems hopeless.” Those who used screens less, spending time playing sports or socializing with friends in person, were less likely to report feelings of depression.
This, in fact, is not the first time that scientists have found that social media can rob people of their happiness. One study published in 2016 asked a randomly selected group of adults to quit Facebook for a week. It turned out that they reported feeling less depressed at the end of the week than those who continued using it.
Some research, however, suggests that social-networking sites can promote happiness if used to engage directly with other users, rather than just to feel jealous of happy moments someone shares online. This provides a reminder that it is users’ attitudes that shape their experiences on social media.“I often remind myself that it's all filtered," reflects Sarah, a junior at the high school in Los Angeles. “People only post what they want you to see, so it can seem that their life is superior to yours.” But when asked if she has ever considered deleting her social media accounts, Sarah looks confused.“No. I would feel lost.”
【1】What is the topic of the passage?
A.Feelings of depression. B.The rise of social media.
C.Addiction to recreation. D.The use of smart phones.
【2】What can we learn from the two studies in paragraph 3 and 4?
A.Sports and socialization are supposed to be encouraged.
B.Most American teenagers have sunk into hopelessness.
C.Social media have negative effects on people's feelings.
D.People are not in a position to live without social media.
【3】According to Sarah, what is the right attitude to others’ happy moments shared online?
A.Jealous. B.Critical. C.Concerned. D.Tolerant.
23、 The high Andes mountains of Peru are a hummingbirds’ paradise(蜂鸟的天堂), rich in wildflower nectar(花蜜)and low in natural enemies. But there’s one problem: the cold.
Nighttime temperatures often dip below freezing in these rainy tropical highlands. How does a six-gram bird that needs nectar from 500 flowers a day just to survive get enough extra energy to keep itself warm all night? It doesn’t. Instead, as temperatures drop, these hummingbirds enter a state known as torpor(冬眠). One species, the black metaltail, cools to 3.26℃, the coldest body temperature ever recorded in a bird or non-hibernating mammal(非冬眠的哺乳动物), researchers report in Biology Letters.
“They’ re cold as a rock,” says Blair Wolf, a physiological ecologist at the University of New Mexico in Albuquerque. “If you didn’t know better, you’ d think they were dead. Cooling to near-death temperatures lets the hummingbirds save precious energy, allowing them to survive the cold night and get ready to feed the next day.”
Standing upright, the birds pointed their bills upwards, loosened their feathers and stopped moving. All of the species entered some kind of torpor, but the black metaltail cooled the most, dropping from a daytime temperature of about 40℃ to just above freezing.
“During the day, these hummingbirds’ hearts can beat 1,200 times a minute to power their crazy lifestyle. But during torpor, their heart rates drop to as low as 40 beats a minute. It’ s an astonishing drop,” Wolf says, “and it could allow these high-altitude birds to cut their energy use by about 95 percent. By not wasting energy trying to stay warm, these birds can live as high as 5,000 meters above sea level.”
When the sun begins to rise, the hummingbirds start warming about a degree a minute by shaking their muscles. “You see the bird trembling there, then all of a sudden its eyes pop open and it’ s ready to go, ” Wolf says.
【1】What makes Andes mountains a perfect living place for hummingbirds?
A.Its high altitude. B.Its climate conditions.
C.Its animal species diversity. D.Its abundance of wildflowers.
【2】How does the black metaltail hummingbird survive cold nights?
A.By freezing itself nearly solid. B.By eating enough nectar before dusk.
C.By stopping breathing and heartbeats. D.By hiding its bill in its loosened feathers.
【3】What do Wolf’ s words reflect about the hummingbirds?
A.They tremble for warmth at night. B.They consume no energy at night.
C.They are quite adaptive. D.They have a big heart.
【4】The hummingbird’ s warming process _________.
A.ends before sunrise B.takes 40 minutes or so
C.is rather difficult D.happens with its eyes open
24、 Not all the historians in Canada are historians of Canada. Case in point: Timothy Brook.
Brook was born and schooled in Toronto, and he now teaches in Vancouver. But he’s a historian of China, and his recent book Vermeer’s Hat seems at first to be about Holland in the period of the Dutch masters. When I met Brook recently in Vancouver, he did seem truly a global historian. Vancouver is his home, but Vermeer’s Hat has been published around the world.
Brook was just in from Oxford, UK, where he taught part of the year, by way of New York, where Vermeer’s Hat had just been given the Lynton History Prize. He was about to go to California, where he was due to lecture. Still, the author and the book---and the hat---say something fresh about Canada and the world.
“I’ve been looking at Vermeer since 1971,” says Brook. Looking at Dutch interior (室内的) scenes from the mid-1600s, he noticed maps, Chinese porcelains (瓷器), South American silver, Virginia tobacco—all marking the influences of the wide world. In Brook’s telling, Vermeer’s masterworks become doorways to the world, and not least to the largest, richest nation in the world, the China of the late Ming Empire, a field in which Brook happens to be a specialist.
Brook used global history as a way to find common ground with fellow historians. “The sixteenth century is the age of discovery, but the seventeenth century is the age of people starting to move the possibility of a global economy, intercultural relations across the globe,” he said.
It proved not hard for this Canadian historian of the world to find Canada in world history--or the world in Canadian history. In Vermeer’s 1658 painting of a Dutch soldier in a wonderful hat, the felt (毛毡) for the hat was probably made in Lachine, from French la Chine meaning China. Established in Canada by de Champlain, the town was so named because Champlain, like other explorers the French explorer Samuel was hoping to get through Canada to China.
【1】Which was the line of Brook’s recent journey back home .
A. Toronto--Oxford→ Vancouver
B. Oxford→ New York→ Vancouver
C. California→ Toronto→ Vancouver
D. New York→ California→ Vancouver.
【2】Which is discussed in Brook’s Vermeer’s Hat?
A. The Lynton History Prize
B. Ways to give good lectures
C. The Ming Dynasty of China
D. A hat Vermeer wore for years
【3】What can we infer about Vermeer?
A. He was a Dutch painter
B. He was a French explorer
C. He was a UK publisher
D. He was a US teacher
【4】What can be suitable title for the text?
A. The Influences of masters’ books
B. An age of moving and possibilities
C. The Importance of Cultural Exchange
D. A Canadian Historian Thinking Globally
