Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two periods—clinical or temporary death and biological death. Clinical death occurs when the important organs, such as the heart or lungs, have stopped to function, but have not suffered permanent damage. The organism (有机体) can still be revived. Biological death occurs when changes in the organism lead to the “breaking up” of important cells and tissues. Death is then unchangeable.
Scientists have been seeking a way to lengthen the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic (麻醉的) sleep. By slowing down the body’s metabolism (新陈代谢), cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery (动脉). The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe (注射器) and ran with it around the room. It showed that Keta had nothing different from any other healthy animal.

【推荐2】A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.
Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants(抗氧化剂), iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.
Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, “From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy.”
“It’s thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells,” Ambrosone said.
Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. “But there was no strong empirical data for that recommendation,” Ambrosone said.
So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy’s effectiveness. They looked for evidence in an earlier study on diet exercise, lifestyle and cancer results.
In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.
The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.
1. Why did Ambrosone and other researchers conduct the study?A.To know about the patients’ lifestyle. |
B.To see whether patients take supplements. |
C.To seek evidence for the recommendation. |
D.To examine chemotherapy’s effectiveness. |

【推荐3】Ms. McIntyre, 38, worked as a publisher. She suffered brain cancer and her health got worse despite some medical treatment. But she realized that in a way, she was luckier than some other people. She had insurance to help pay for her medical care. But Ms. McIntyre and her husband, Mr. Gregory, knew that many people with cancer face tough decisions because of the costs of medical care and wind up owing far more than they can pay.
Though her health was failing, Ms. McIntyre decided to help pay off the medical debts of as many people as she possibly could. The couple began donating money to a group called RIP Medical Debt, which is committed to working to pay off the unpaid medical debts of others. The group can pay off medical bills for about 100 times less money than they cost. In other words, for every 100 donated, the group can pay off 10,000 in unpaid medical bills.
Unfortunately, Ms. McIntyre passed away before long. Mr. Gregory posted a message for Ms. McIntyre on her social media accounts. “If you’re reading this, I have passed away,” the post began. Then the post explained, “To celebrate my life, I’ve arranged to buy up others’ medical debts and then destroy the debts.”
The couple had set up a page on a website to raise money for this purpose. They had hoped to raise about $20,000. Nevertheless, Ms. McIntyre’s last post attracted a lot of attention. The donations on her web page quickly passed the total goal. In less than a week, the site had raised 10 times more than expected and the donations are still coming in. By November 22, 2023, Ms. McIntyre’s web page had raised over $627,000, or enough money to pay off about $60 million in medical debts.
Mr. Gregory planned a special event in December to celebrate Ms. McIntyre’s life and to announce how many millions of dollars of medical debts her efforts had paid for.

【推荐1】China has abolished (废除) its controversial birth restrictions, reversing (彻底改变) nearly four decades of family planning policies as birth rates fall.
China began implementing (实施) the one-child policy in the 1980s to slow population growth. But in recent years concern is accumulating that an ageing and shrinking workforce could slow China’s economy, while gender imbalances could lead to social problems. And the limit was raised to two children in 2016 as the nation tried to rejuvenate (使恢复活力) its ageing population of 1.4 billion.
However, child births have not increased as much as forecast since the two-child policy came into force. Couples have been in no rush to start larger families since the policy was loosened, with 17.9 million babies born in 2016 — just 1.3 million more than in the previous year, half of what was expected, according to the National Bureau of Statistics. Births in 2017 even slipped to 17.2 million, well below the official forecast of more than 20 million.
And there has been an assumption that the government will further ease restrictions. Other changes include a one-month cooling-off period before a divorce, during which either party (一方当事人) can withdraw their application.
News of the changes lit up social media. “So they want us to have more babies and fewer divorces? ”wrote one user on Weibo, China’s equivalent of Twitter. “The created generation, us only children, let’s gather together and prepare to work into old age,” another user wrote. “Having children is good, which eases the government’s health care cost for the elderly. ”
Hong Fincher said it remained to be seen how the Chinese government would adopt any changes. She said incentives(激励) to have more children had not worked and that the government might resort to other measures.
1. Why was the one-child policy adopted in the 1980s?A.Because of the booming population. | B.Because of the severe social problems. |
C.Because of the imbalanced gender ratio. | D.Because of the rapidly ageing population. |

【推荐2】My daughter, Liora Saraik, aged 13, is beautiful, positive and humorous. Her father and I love her, but she has life-long conditions: uncontrolled epilepsy and autism. She meets the government’s definition of vulnerable and should have been able to go to school when lockdown started.
So why are we not sending her to school? On the first day of the lockdown, I spoke to a school staff member on the phone. “It’s up to you, of course, but I wouldn’t send her,” he said. “I can’t see how it can be safe.”
Many of the pupils like Liora, can’t speak or understand simple words such as food, drink, toilet. They don’t know anything about the virus. Many are also violent to parents and teachers and they are not able to stop biting, punching and kicking. Liora is not violent to others, but she is to herself, banging her own head with her fists when in pain or frustrated.
Liora’s head teacher, Adrian Carver, says if he lets more children into school, they could simply die of contracting coronavirus. He has to run desperate parents away, which he hates doing, as he knows it is not easy for us.
But clearly he has no idea of how hard it is for thousands of families in the crisis to care for their vulnerable children full-time. Parents like myself can’t provide what a school can offer. We have constant big challenges with personal care, and with sleep deprivation, as our children are often up in the night. Without school, it’s not only our children who are vulnerable, it’s the whole family.
So what do we need? I want recognition at the highest level for families caring for their disabled children. I want professional carers to be valued and paid properly for their specialist skills caring for children like Liora. Skilled carers leave their jobs because their wages are so low. We parents are in a constant fight with each other, first to get carers and then to keep them — we are like rats in a trap.

Some historians believe that he is based on a real person, Samuel Wilson. During the War of 1812, Wilson sold meat to American troops. Wilson labeled the meat barrels (桶) US. This meant that it was for the army. At that time, US was not used to mean “United States”. An officer asked what the US on the barrels meant. A soldier replied, “United States”, meaning Samuel Wilson.
The Uncle Sam image (形象) today shows a man with a beard, a stars and stripes (星条旗) top hat, and a suit. Thomas Nast created this image in about 1838. It represented the government in Nast’s political cartoons. Some people believe that Nast based his image on Dan Rice, a popular entertainer. Rice performed while wearing a top hat and suit.
Others think it was James M. Flagg that drew the most famous image of Uncle Sam in 1917, during World War I. It shows a serious man pointing a finger at the viewer and says “United States”. Flagg drew this enduring image to encourage Americans to join the U.S. Army. It has been used for this purpose ever since.
Today, Uncle Sam is a symbol of the United States that is recognized around the world.

【推荐1】Bonnie often walks on two legs, like humans. And you can find the 32-year-old great ape copying her keepers by sweeping the floor of her zoo home. Sometimes she uses a piece of cloth to clean the window.
“Apes (猿) in general are very clever, but Bonnie is surely even more so,” said Erin Stromberg, a great ape keeper who works with Bonnie and recently wrote a research paper about her ability to whistle.
Bonnie is one of the six adult great apes at the National Zoo. Bonnie and other great apes are part of a research project. Scientists there are trying to learn more about the way the great apes think and act. One part of the project is to learn whether great apes can develop a way to remember long lists.
Stromberg helped with a project on Bonnie’s unusual ability to whistle. Years ago Bonnie started to whistle, probably after hearing a keeper do it. In the project, Stromberg made different whistling noises to see if Bonnie could repeat them. She did. Bonnie’s whistling shows some apes have the ability to learn a new sound from another species.
The finding is especially important because, Stromberg said, it can help scientists better understand how human speech developed. Great apes, after all, are the closest relatives to human beings in the animal kingdom.
Bonnie was born in 1976 at a zoo in New Mexico and arrived at the National Zoo in December 1980. Bonnie has physical features common to great apes, such as a large belly. Her dark red coat makes her easy to spot on a visit to the zoo.

【推荐2】Once an Englishman named Larry Belmont went to Russia for a holiday. After he got back, some of his friends came. “I had a very dangerous trip while I was in Russia,” Larry said. “I went to see a friend in the country when the sun went down, I was still travelling through a forest in a sleigh(雪橇). It was a long way from my friend’s house when about twenty wolves began to follow my sleigh.”
“It was very dark in the forest. There was thick snow on the ground. First I heard the wolves. The noise was terrible! Then I saw long, grey forms among the trees, and soon the wolves were near me. They were running very fast, and they didn’t seem to get tired like the horses.”
“What did you do?” one of Larry’s friends asked.
“When the wolves got very near,” Larry answered, “I put up my gun and shot the first wolf dead. Then all the other wolves stopped and ate it, so my sleigh got away from them for a few minutes. Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another one of them, and the others stopped once more to eat it. The same thing happened again, and my horses became more and more tired and ran slower and slower until, after two hours, only one wolf was still alive and following me.”
“Wasn’t it too fat to run?” one of Larry’s friends asked.

【推荐1】Ann started to work last summer. In order to have a holiday, she saved as much as she could and, this January, she booked a package tour to Spain. She left London airport early on the morning of the first Saturday in August. She was very excited, as this was her first trip abroad. When she arrived at Barcelona airport, the weather was beautiful.
At the hotel, she found that her Spanish money wasn’t in her handbag. All she had was a small purse with ten English pounds in it!
Ann found a place to change her English money for Spanish money. She would stay here for two weeks. After changing her money, Ann bought some cheese, some bread and some oranges. When she got back to the hotel, she told the tour guide that her doctor had told her not to eat much food, so she’d just have breakfast each day. This was all right, as she knew breakfast was included in the price of hotel.
For the rest of her holiday, Ann swam in the hotel or lay on the beach. She also went for long walks with Jane, a Scottish girl. However, when the others went to interesting places, Ann always said she wasn’t well. In fact, her holiday wasn’t bad, except that she was always hungry.
On the last day, Jane asked her why she never ate with them in the hotel restaurant. The food was excellent. Ann told her all about her money problem. Jane looked at her for a minute, and then said, “But didn’t you know? The price of this tour includes everything!”

【推荐2】No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
Let’s take a man we’ll call Mr. Fielder, for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn’t make the bricks for his house, grind the wheat for his flour, or cut his trees into boards. He also did not make the plows (犁), the work boots, or any of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people’s attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this primitive form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today’s world.

【推荐3】“Smombies”— people walking while staring at their smartphones are very real and a growing cause for concern. To let people pay more attention to their surroundings to avoid serious accidents, government in a small German town has come up with a more positive solution — embedding (嵌入) traffic lights in the pavement to make them noticed by people always looking down at their phones.
The safety measure was taken. Authorities in Augsburg decided to act, installing ground level traffic lights at two tram (电车) stops last Tuesday. The lights flash red when a tram is coming, or when the regular traffic light turns red. “We realized that the normal traffic light isn't in the line of sight of many pedestrians these days,” said Tobias Hermes, a city official. “So we decided to have an extra set of lights — the more lights we have, the more people are likely to notice them.”
Some Augsburg people appear to be quite happy with the idea. “I think it makes sense,” Jack Smith said, speaking to The Augsburg Alleghenies. “One always sees young people these days running over red lights. This makes it more obvious that you need to stop.”
Others, however, found the need for ground traffic lights unnecessary and even frightening. “I find it scary that smartphone users are so engrossed that they need to install lights in the ground so that they notice the tram coming,” one person told the local paper.
But do this kind of pavement-embedded lights actually work? One interviewed teenager believes not really. “To be honest, I didn't even notice it,” he told The Augsburg Alleghenies. "Maybe it’d be useful at night, but I didn’t realize it was there until just now.”
