    The world's oceans will likely lose about one-sixth of their fish and other creatures within 100 years if climate change continues on its current path. Every degree Celsius that the world's oceans warm, their biomass is expected to drop five percent, a study found.

    The study predicts that if there is no change in the rate of worldwide greenhouse gas production, there will be a 17-percent loss of biomass by the year 2100. But, if the world reduces carbon pollution, biomass losses could be limited to only about 5 percent.

    Warming temperatures are the biggest issue. But climate change also produces oceans that are more acidic and have less oxygen. This also harms sea life. Much of the world depends on the oceans for food or work.

    The findings make sense and the possible effects of the predicted losses of animal life are huge. "Climate change has the potential to cause serious new conflicts over ocean resource use as the human population continues to grow," said scientists.

    Marine biologist Boris Worm, who helped run the study, added that the "building blocks of marine life—plankton and bacteria—may decline less heavily."

    "Those marine animals that we use directly, and care about most deeply, are predicted to suffer the most," said Worm. He works at Canada's Dalehousie University.

    Scientists had already believed climate change would likely reduce future ocean life. But past computer-based studies looked at only part of the picture or used only one model. The latest study used six different computer models to give the best picture look yet, William Cheung said.

    University of Georgia marine biologist Samantha Joye was not part of the research. But she praised the study as well researched and extremely detailed, and called it "an urgent call for action".

(1)、What does the underlined word "biomass" in paragraph 1 refer to?
A、Ocean temperature. B、Total marine life. C、Sea condition. D、Ocean level.
(2)、Why do scientists think that climate change might cause conflicts?
A、It may reduce the sea resource. B、It leads to the extinction of marine life. C、It pollutes the environment of the ocean. D、It may increase the world population.
(3)、Which sea animals will be harmed the worst by sea warming?
A、The largest ones. B、The ones in deep oceans. C、The bacteria on sea surface. D、Those we humans need most.
(4)、What makes this study different from previous studies according to William Cheung?
A、Purpose of the study on oceans. B、Computers used in the research. C、Improvement of research methods. D、Discovery of damage of climate change.

    Reducing the amount of sleep affects students' performance at school. An American study asked schoolteachers to look at the effects of sleep restriction(限制) on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.

    {#blank#}1{#/blank#} Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C. The Publication Sleep also reported the findings.

    The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.

    {#blank#}2{#/blank#} During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.

    The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficulty remembering old information. {#blank#}3{#/blank#}

    The study did not find that sleep restriction caused hyperactivity(极度活跃) in the children. {#blank#}4{#/blank#}

    Doctor Fall one said that the results provided experts and parents with a clear message: {#blank#}5{#/blank#}

A. The sleeping time that the students have can be changed easily.

B. They also had trouble learning new information, completing difficult work and following directions.

C. During one week, the children went to bed and awoke at their usual time.

D. The teacher should restrict the amount of sleep of the students.

E. Gahan Fallone did the study at the Brown Medical School and Bradley Hospital in the state of Rhode Island.

F. The teachers reported that students were, in fact, a little less active at school when they got less sleep.

G. When a child has learning problems, the issue of sleep must be considered among the possible causes.

    For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up to date. They're documenting why teaching is such a fruitful w ay to learn, and designing creative ways for young people to take part in instruction.

    Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others? One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings(兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They arrange college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic.

    But the most cutting-edge tool under development is the "teachable agent" — a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil.

    Computer scientists have created an animated(动画的)figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are inspired to help Betty master certain materials. While preparing to teach, they organize their know ledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking.

    Feedback from the teachable agents further improves the tutors' learning. The agents' questions forces student tutors to think and explain the materials in different ways, and watching the agent solve problems allow s them to see their know ledge put into action.

    Above all, it's the emotions one experiences in teaching that improve learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they develop pride and satisfaction from someone else's accomplishment.

    Three months after Hurricane Katrina in 2005, Rebecca Sell, then 24, a photojournalist for Fredericksburg photographed a New Orleans couple worriedly examining water-spotted photo albums. As she took the photo, something within her clicked. "I told them I could take the ruined pictures, copy them and give them digitally restored (修复) photos," she recalls. Although a bit sceptical, the couple agreed. Rebecca took their photos home, restored them and took them to the couple at their temporary home. "It felt so good to be able to do that for them," says Rebecca.

    When her editor, Dave Ellis, saw the photo of the couple, he suggested they go back and restore damaged photos for even more people. So in January 2006, with paid time off from the paper, the two set up shop in Pass Christian. After posting a notice in the community newsletter, Rebecca and Dave received 500 photos in four days. For each, the pair took a new digital picture, then used high-tech software to erase water spots and restore colors. It just so happened that a popular website linked to Dave's blog about the experience, and soon Operation Photo Rescue, as it came to be known, had emails from hundreds of volunteers, including photographers and restoration experts, eager to help.

    Though digital restoration is a painstaking process, mending irreplaceable family pictures means the world to victims like Emily Lancaster, 71, who took out piles of ruined photo albums after Katrina, never thinking the mess could be saved. But she just couldn't bear to part with a few treasured pictures, including a portrait of her father, who had passed away, and a photo of her husband as a boy. Then she heard about Operation Photo Rescue. "I didn't have a whole lot of hope they could fix them, but they did," Emily says. "Almost every day I think about all the pictures I've lost. I'm so happy to have these two."

    In the five years since Katrina, Operation Photo Rescue has collected thousands of pictures ruined by floods, hurricanes and tornadoes. Volunteers make "copy runs" to disaster areas across the country to gather damaged photos from survivors; operating costs are covered by donations. "It's great to be able to give people some of their history back," says Rebecca. "One person told me that thanks to us, her grandmother got to see her photos again before she passed away. Moments like that remind me why I do this."

    Scientists are attempting to extract (提取) cells from a 40,000-year-old horse in hope of using the sample to clone the extinct (灭绝的) species back into existence. The male baby horse was discovered in 2018 in permafrost (永冻土) in northeastern Siberia of Russia.

    A team of scientists from South Korea and Russia believes the young horse, called the Lenskaya or Lena horse, was about 20 days old when it died. The species of horse, now extinct, is between 30,000 and 40,000 years old. Thanks to the terrible coldness, the animal's tissue was preserved enough for the scientists to obtain samples.

    Semyon Grigoriev, head of the lab at the Mammoth (猛犸象) Museum of the North-Eastern Federal University in Yakutsk, said the horse was "well - preserved" and a "great find". There is no damage to the horse's body and even its hair is undamaged. The unfortunate animal, according to Gngo-riev, "could have drowned after falling into some kind of a natural trap."

    Hwang Woo-suk, a researcher from South Korea working on the project, said, "If researchers find a cell, they will do their best to clone the animal. If we get live cells from this ancient baby horse, it would be wonderful in terms of cloning."

    After that, they will make a cloned embryo (胚胎) and a female horse carry it as its mother. Hwang said modern-day horses are "very similar to the ancient one," so there would be no problem getting help from a modern-day female horse.

    The scientists are hoping the experiment on the baby horse will give them experience in progressing toward their ambitious goal-bringing back the extinct woolly mammoth.

    "If we manage to clone the horse-it will be the first step to cloning the mammoth." Hwang said.

    A disastrous fire surrounded Notre Dame(巴黎圣母院)destroyed large parts of the Gothic architecture on Monday.

    "Notre Dame is our history, our literature, part of our spirit, the place of all our great events, our wars, our liberations, the center of our lives" French President Emmanuel Macron told reporters in front of the still burning Paris landmark and promised to rebuild Notre Dame.

    "Notre Dame is burning, and I know the sadness felt by so many fellow French people. But tonight, I'd like to speak of hope too, "he said, announcing the launch of a fundraising campaign.

    "Let's be proud, because we built this cathedral(大教堂)more than 800 years ago, we've built it and, throughout the centuries, let it grow and improve it. So I gravely(严肃地)say tonight: we will rebuild it together." he added.

    The disastrous fire engulfed(吞没)the upper reaches of Paris'towering Notre Dame Cathedral as it was undergoing renovations(翻新).

    Tourists and Parisians looked on horrified from the streets below. France's Interior Ministry said firefighters might not be able to save the structure.

    The fire collapsed the cathedrals' spire(尖顶)and spread to one of its landmark towers "Everything is burning; nothing will remain from the frame," Notre Dame spokesman Andre Finot told French media. The 12th-century cathedral is home to incalculable(不可计算的)works of art and is one of the world's most famous tourist attractions, due to Victor Hugo's novel The Hunchback of Notre Dame.

    The cause of the fire was not known, but French media quoted the Paris fire brigade(消防队)as saying the fire is "potentially linked" to a 6 million- euro($6.88 million)renovation project on the church's spire and its 250 tons of lead. Officials opened an investigation as Paris police said there were no reported deaths. Some 400 firefighters were battling the fire well into the night.

Humans act with purpose, but much is still unknown about how we become purposeful agents — that is, how we develop the ability to willfully make things happen. In a recent study to explore agency's mysterious roots, we tried to catch infants (婴儿) in the act of discovering their own agency, thereby revealing the process of agency formation.

Researchers place a baby into a cradle with a mobile suspended above. Then a scientist ties one end of a string to the mobile and the other to the infant's foot. Now if the baby moves, the toy will, too. By observing babies in this setup, scientists can watch as the infants learn and recall a simple cause-and-effect interaction: kick a foot and the mobile moves.

As predicted by the researchers, infants kicked significantly more when their foot was tethered (拴住) to the mobile than when it was not. However, when an experimenter pulled the string to make the mobile move instead, infants moved less than when the mobile was at rest. Furthermore, when we freed the babies' foot from the mobile, they kept on kicking at higher rate to make the toy respond — and were visibly frustrated when that did not happen.

Our observations also pointed to a notable pattern: The babies' initial movements consisted of twisting and pushing without clear direction. But once tethered to the mobile, the more intensely they moved, the more their attention was drawn to the effect their kicking had on it. At some point, the infants must have figured out that they had agency, thus the aimless movements became intentional action — a highly coordinated exchange between the tethered infant and the mobile.

The baby-mobile study emphasizes how understanding the relationship between an organism and its environment is essential to uncovering the origins of directed behavior. The experience of agency emerges only when an organism senses it is coupled to its environment. In this way of thinking, the interaction and relationship between the two are crucial for purpose to arise.
