Good Genes Mean Long Life

Scientists have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes you have.

For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern (组合).

The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.

The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.

Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.

The studies show that tiny mutations (变异) in the make-up of some genes can greatly increase a person’s lifespan (寿命). Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.

David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.

“If we know which genes control longevity (长寿) then we can … target them with drugs. That makes it possible to slow down ageing,” he told The Times.

“Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged (义不容辞的) to take it.”

1.According to the article, which of the following is the most important if a person is to live to the age of 100?

2.According to the article, the ApoC3 gene is found in ________ of people over 100 years old.

3.Which of the following statements is TRUE of the research led by Professor Nir Barzilai?

4. According to David Gems, ________.

American researchers have discovered that human brains and sleep patterns are confused by devices(装置) that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of insomnia.

Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it.

A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone (荷尔蒙) called melatonin that makes us sleepy.

Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive (干扰的)during the night when the brain thinks it should be dark.

Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp(灯) light doesn't affect the brain as it does not look straight into a person's eyes.

“Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating (刺激) to the brain to make it more awake and delay your ability to sleep，” Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN.

“And I think more importantly, it could also be enough to affect your circadian (昼夜节律的) rhythm. This is the clock in your brain that determines when you sleep and when you wake up. ”

Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, “I wish people would just take a boring book — an old­fashioned book — and read by a lamp.”

1.The underlined word “insomnia” in the first paragraph probably means “________”．

A．being unable to eat properly

B．brain injury

C．being unable to fall sleep

D．lack of energy

2.Melatonin is the hormone that ________.

A．makes us sleepy

B．helps us relaxed

C．prevents us from waking up

D．makes us excited

3.The bedside lamp light doesn't affect the brain because ________.

A．it doesn't give out blue light

B．it's not as bright as your laptop

C．it doesn't enter your eyes directly

D．it is adjustable

4.We can conclude from the passage that ________.

A．one who uses his laptop often before bedtime can have his body clock disturbed

B．using a laptop before bedtime is more harmful than using an iPad

C．we'd better not do anything before going to bed

D．the best time to go to bed is before 9 pm

Now scientists have discovered the first evidence that the animals actually behave like their masters. Just like children, they adopt a “look and learn” approach which means they can mimic (模仿) human's actions when going about their tasks.

Biologists and psychologists at the universities of Vienna and Oxford designed an experiment to test the theory that dogs do have the ability to copy what they see, using a simple wooden box. In the study, ten owners showed their dogs how to open the wooden box, sometimes using their heads to push a handle and sometimes using their hands.

In the first part of the test, five dogs were rewarded with a piece of sausage for copying their owners' actions. The other five were rewarded with food for not copying, and using other methods. With each dog the experiment was repeated hundreds of times, and the time taken for a dog to get it “right” on 85 percent of attempts (17 goes out of 20) was recorded. The dogs encouraged to mirror their owners reached this point almost three times sooner on average than those rewarded for not copying them. In the second part of the test, all the dogs were only rewarded for copying the method their owners used. The five dogs previously rewarded for copying their owners reached the 85 percent mark more than twice as the other five.

In a paper published in Proceeding of the Royal Society, they concluded, “Like humans, dogs can't help imitating actions they see.” Going further, they said, “The results suggest the imitative (模仿的) behavior of dogs is shaped more by their developmental interactions with humans than by their evolutionary (进化的) history of domestication (驯化).”

Caroline Kisko, from the Kennel club, said, “A dog's behavior is influenced much like that of a child learning right from wrong and adopting similar patterns of behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore positively influence the behavior of their pets.”

1.What's the best title of the passage?

A. Dogs Are Intelligent Animals

B. Dogs Are like Children Most

C. Dogs Behave like Their Masters

D. Dogs Can Complete Simple Tasks

2.The underlined part “they” in Paragraph 4 most probably refers to ________.

A. the dogs' masters

B. the magazine's publishers

C. all the people involved in the experiment

D. the biologists and psychologists

3.The researchers believe dogs' imitative behavior comes mainly from ______.

A. domestication　　　　　　　 B. human rewards

C. evolution　　　　　 　　　 　 D. human-dog interactions

4.What can be inferred from the last paragraph?

A. Masters should influence their dogs as early as possible.

B. A man's bad behavior may influence his dog.

C. Dogs can't be influenced by men easily.

D. Dogs always behave positively.

On Tuesday, scientists announced that they have discovered the bones of four settlers in Jamestown, Virginia. Jamestown was the first permanent English settlement in what become the United States. The bones were unearthed under the floor of a Jamestown church which was discovered in 2010 and is considered as America，s first Protestant church.

The Jamestown Rediscovery Foundation at Historic Jamestowne and the Smithsonian's Museum of Natural History announced that the settlers held high leadership positions. The men, Rev.Robert Hunt,Capt. Gabriel Archer,Sir Ferdinando Wainman,and Capt. William West, all played a role in the Jamestown settlement. After being lost to history for more than 400 years, the discovery of their remains provides new clues about their life and the importance of religion in the 1600s.

“This is a very important discovery,” Jamestown Rediscovery Foundation President James Horn said in a statement. “These men were among the first founders of English America."

About 100 people settled along the James River in what would become the first English settlement m 1607. During that time, settlers in Jamestown were faced with famine and disease The colony was nearly wiped out due to conflict with Native Americans in the area and with other English settlers.

"They lived and died at a hard time in the history of the settlement , when Jamestown almost ended in  failure," Horn said. “The bones of these men help fill in the stories of their lives ”

The Smithsonian and the Rediscovery Foundation found the remains in November of 2013. Scientists used 3-D technology to locate the exact gravesites of the men. The team wanted to identify its findings before announcing the discovery. They identified the men using historical records and studied the chemicals of the bones to learn what the men ate and where they came from.

Findings from the burials will go on display within weeks at Historic Jamestowne. The site also plans to honor the men and will keep their bones in a safe place for future study.

1.The bones found in a Jamestown church_____________.

Researchers Jose Cordova and Erich Astudillo have discovered a new molecule(分子) that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay(腐烂). The new molecule they call “Keep 32” has been found to kill the bacteria.

The two have applied for a patent(专利) on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep them at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year.

The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they’ve discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey’s. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved.

Over the years many products have come on the scene with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride(氟化物) into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks.

1.The underlined word “them” in Para. 2 refers to _________.

A. oral care products B. food products

C. new molecules　 　　 D. the harmful bacteria

2.The phrase “come on the scene” in Para. 4 is closest in meaning to __________.

A. performed　　　　　　 B. occurred

C. existed　　　　　　 　 D. arrived

3.What has been a way to reduce tooth decay and even the loss of teeth over the years?

A. Using the molecule “Keep 32”.

B. Killing the bacteria Mutans.

C. Introducing fluoride into drinking water.

D. Cooperating with some big companies.

4.This passage mainly tells us that ___________.

A. many health problems are closely connected to tooth decay

B. the discovery of a new molecule will greatly benefit health care

C. two researchers are discussing their patent with companies

D. researchers discover a molecule that can kill tooth decay-causing bacteria

The fact that ants are fascinating insects has been known for some time. Now, scientists have discovered a large number of wood ants living in an abandoned underground storehouse in Templewo, Poland, despite having no obvious source of food.

Polish zoologist Wojciech Czechowski and his team began studying the underground colony in 2013. They found the ants built a 60-cm high nest in the soil directly over the storehouse vertical air pipe. As years passed, the metal covering on the pipe eroded, leaving behind a hole that thousands of worker ants accidentally slip into each day as they go about their daily chores. The scientists say that there are no sources of food in the storehouse. This means that the insects live in a state of near starvation.

In July 2015, the researchers disturbed part of the ant nest in search of larvae (幼虫), cocoons(茧), and queens. They found nothing, leading them to suspect that the lack of food and cold temperatures made reproduction impossible and that the group tending the nest is entirely made up of non-reproductive female workers. Their population is refilled every year, by a new rain of unfortunate ants that slide down the hole. The researchers say that when they returned in January 2016, the nest had been repaired. It appears that despite the terrible conditions, the worker ants do not stop constructing their nest.

Wood ants are known for their ability to adapt to bad living conditions. In this case, the millions of worker ants trapped in the storehouse have no choice. But instead of losing hope, they are making the best of the situation—a classic example of “when life gives you lesions make lemonade.”

1.How did the wood ants arrive in the storehouse?

A. They fell down there by accident.

B. The research team brought them there.

C. The storehouse builders left them there.

D. They were attracted by the environment.

2.What does the underlined word “eroded” in Paragraph 2 probably mean?

A. Expanded.　　 B. Rotted.

C. Exploded.　　 D. Melted.

3.What did the researchers find in the nest?

A. Larvae.　　 B. Cocoons.

C. A queen.　　 D. Worker ants.

4.Why did the population of wood ants remain steady?

A. They had enough food.

B. They were able to reproduce.

C. They adapted to the conditions.

D. They had new comers to join them.

Spreading truth and knowledge

If you have ever talked to doctors in the hospitals, you may find that many of them are quite serious and speak in a range of terms that may be difficult to understand. But Zhang Wenhong, the leader of the Shanghai team of experts in the treatment of novel coronavirus pneumonia, is one of the exceptions. He caught the public's attention for his recent frank and funny speech.

Zhang's words first went viral (走红) on the internet after he said in late January that he had dispatched (派遣) doctors and nurses who are members of the Communist Party of China (CPC) to frontline hospitals to treat coronavirus cases.

“When becoming CPC members, we vowed (发誓) that we would always prioritize people's interests. . . in the face of difficulties,” Zhang said. “This is the moment we live up to the pledge (誓言). All CPC members must rush to the frontline. No bargaining.” Such a hardcore declaration of his attitude won widespread applause among internet users. A person's morals are witnessed most in a critical situation. Nothing could win more recognition from the people than the down-to-earth behavior of the CPC members,” said Yang Haiyan, a 32-year-old Shanghai resident.

One month later, when Zhang advised local residents to reduce the risk of spreading the virus by staying at home, he said in Shanghai dialect: “If you don't stop seeing friends, you will see them again in the ICU.”

Though chased by the media, Zhang described himself as a medical worker who must speak out now, but will return to keeping a low profile after the outbreak ends.

“I spoke because of the fear among the public, owing to limited knowledge of the contagion (传染病),” said Zhang on Feb 26. “However, once the curtain of this coronavirus incident falls, it may be hard to find me. I'll just hide myself in a corner, studying complicated patient cases and doing some reading, silently. ”

1.What has made Zhang Wenhong so popular online?

A.The way he treats his patients.

B.His honest and humorous speech.

C.His pledge to fight against the virus.

D.His broad knowledge of the novel coronavirus.

2.He dispatched CPC members to frontline hospitals because he believed that 　　　　 .

A.they would bargain less

B.they are more professional

C.they should take the lead as they had vowed

D.they would be calmer in a critical situation

3.What can we conclude from Zhang Wenhong's words in the last two paragraphs?

A.He doesn't like to speak in public.

B.He mainly treats people with complicated diseases.

C.He is not a person who is after fame and attention.

D.He is looking forward to taking a break after the epidemic.
