【推荐2】How do you feel about nature? After spending hours indoors, do you feel better when you visit your local park? Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. In some countries such as the USA, only 10% of the teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty-first century.

Some doctors find nature and health are interrelated. One example of this is the work of Dr. Matilda in Sweden (瑞典). The doctor gave people a maths test. During the test, their heart rates (率) were fast. After the test, one group of people were chosen to sit in a 3D-virtual-reality (虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than the others’. Another good example of how nature is good for health comes from Canada. In Toronto, researchers studied 31, 000 people living in the city. In general, they found that healthier people lived near parks.

Because of studies like these, some countries and cities want nature to be part of people’s everyday life. In Dubai, for example, there are plans for a new shopping mall with a large garden so shoppers can relax outside with trees, plants and water. In Switzerland, “forest schools” are popular. Students study their subjects in the forests and do lots of exercise outside. And South Korea is another good example. It has new forests near its cities and around 13 million people visit these forests every year. So after building cities for so long, perhaps it’s now time to start rebuilding nature.

【推荐3】Forgot your password (密码) or your ID? Well, you’ll never forget your face. Using your face as your ID is quick and convenient. You could take the subway or board a flight with just your face alone. This is how facial recognition (人脸识别) works. It has also been used to catch criminals (罪犯).

In China, facial recognition systems have been used in many areas. In Zhengzhou, people can now get on the subway by using facial recognition technology. They just need to link their online payment systems to the subway’s smartphone app. Students at Peking University can pass through the school’s gate by scanning their face.

However, there are no laws to regulate (规范) the use and collection of facial information. Many citizens are worried about the collection and use of this information by governments and companies. Why is it necessary to collect data (数据) about your face and what will the data be used for? These are some common questions on the facial recognition.

“I feel uncomfortable because I don’t know how the company is using my facial information or whether the company will leak my facial information,” Feng Yi, a tourism company employee (雇员) said. Leaks are a problem because there is a long history of companies failing to protect our data. When someone steals your personal information, you can change your bank card and password, but can you change your face when your facial information is stolen?

As facial recognition is used more and more in our daily lives — from college campuses and subways to street corners and smartphones — we must ask ourselves whether this new technology is worth the risk or not.

1. It’s ________ to use your face as your ID.

A．slow

B．inconvenient

C．quick and convenient

D．complex (复杂的)

2. What has not facial recognition been used to do?

A．To take the subway.	B．To board a flight.
C．To catch criminals.	D．To borrow money from a bank.

3. The underlined word “leak” probably means in Chinese in this passage.

A．收藏

D．泄漏

4. Which of the following is TRUE?

A．Using face as your ID is quick and inconvenient.

B．Students at Peking university can go through any gate with facial recognition.

5. What’s the writer’s attitude (态度) towards facial recognition?

A．The writer suggests that we ourselves should be very cautious (谨慎).

B．The writer doesn’t support facial recognition at all.

C．The writer doesn’t express at all.

D．The writer supports facial recognition.

【推荐1】About 21,000 young people in 17 American states do not attend classes in school buildings.
Instead, they receive their elementary and high school education by working at home on computers. The center for Education Reform says the United States has 67 public “cyberschools(网络学校)” and that is about twice as many as two years ago.
The money for students to go to a cyberschool comes from the governments of the states where they live. Some educators say cyberschools receive money that should support traditional public schools. They also say it is difficult to know if students are learning well.
Other educators praise this new form of education for letting students work at their own speed. These people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say learning at home by computer ends long bus rides for children who live far from school.
Whatever the judgment of cyberschools, they are getting more and more popular. For example, a new cyberschools called Commonwealth Connections Academy will take in students this fall. It will serve children in the state of Pennsylvania from ages five through thirteen.
Children get free equipment for their online education. This includes a computer, a printer, books and technical services. Parents and students talk with teachers by telephone or by sending emails through their computers when necessary.
Students at cyberschools usually do not know one another. But 56 such students finished studies at Western Pennsylvania Cyber Charter School recently met for the first time. They were guests of honor at their graduation.
1. What do we know from the text about students of a cyberschools?

A．They have to take long bus rides to school.

【推荐2】It is a question people have been asking for ages. Is there a way to turn back the aging process in people? For centuries, people have been looking for a “fountain of youth.” The idea is that if you find a magical fountain, and drink from its waters, you will not age.

Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus（下丘脑）. The hypothalamus is part of your brain. It controls important activities within the body. They include growth, reproduction and the way we process food.

Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural stem cells also influence how fast aging takes place in the body.

What are stem cells? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.

Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature.

“Aging speed is controlled, can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells.” He adds that when the hypothalamus starts aging, so does the body. “So when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost, it eventually leads to aging.”

Using this information, the researchers began trying to activate, or energize, the hypothalamus in laboratory mice. They did this by injecting the animals with stem cells. Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination of the animals’ muscles. They also studied the social behavior and cognitive （认知的）ability of the mice. The researchers say the results show that the treatment slowed aging in the animals.

“When we injected the hypothalamus stem cells, which were derived from young mice, we injected them to the middle-aged mice and that was, in fact, to slow down aging. So the mouse aged slowly and they also have increased their lifespan, which is longevity.”

But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings. “If we can translate what we have seen in animals to humans, I think humans, they can function better during later ages, later stage of aging.”

Cai and his team say their studies may have other benefits. They say the findings could lead to new ways to help doctors identify and treat any number of age-related health issues.

1. What do we know about the hypothalamus?

【推荐3】Grandparents are respected in many human societies.But telling stories about old times and overfeeding grandchildren seem like distinctly human traits (特征).Are these classic grandparent behaviors really limited to human beings? Do any animals know their grandparents the way people do? For most species (物种) on Earth,the answer is NO! “Usually, there just aren't grandparents living anymore when an animal is born,” said Mirkka Lahdenperä, a biologist at the University of Turku in Finland. Even if an animal's grandparents are still alive, most species spread out to avoid competing for resources, so the chances of running into a grandparent are small.

But there are a few exceptions, primarily among mammals (哺乳动物) that live in close social groups. Canadian zoologist Anne Innis Dagg described groups of langur monkeys in India in which older females lived with their daughters and grandchildren. The grandmother langurs have a particular job: they protect the group's babies against hurt from humans, dogs and other monkeys. Some female langurs even give their own grandchildren special treatment, cleaning their fur and stepping in when they play too roughly with other young.

Many whale species, too, travel with their families,including both grandmothers and grandcalves. In groups of sperm whales, according to Dagg, old females help babysit the group's young while their mothers dive (潜水) for food. Orca grandmothers often lead their family members and can live for many years after they stop reproducing. In 2015, scientists suggested that these elder orcas help their grandcalves through hard times, because they remember all the best places to find food.
Female elephants rule the whole family. Calves (幼崽) are typically born into groups led by their grandmothers, who can live to around 80 years old. The female elephants form close relationships, said Lahdenperä, and raise their young together. Lahdenperä found that the calves of young mothers were eight times more likely to survive if their grandmothers lived near them than if they didn't. When the calves' mothers were older and more experienced at raising babies, this beneficial “grandmother effect” disappeared even if the actual grandmothers were still around.
It isn't very clear how elephant grandmothers help their inexperienced daughters, said Lahdenperä. It is believed that they may help nurse their grandcalves. But Lahdenperä thinks that the more likely advantage is the wisdom a grandmother elephant has got during her long lifetime.
And what about grandfathers? Studies of humans in recent years have shown that a living grandfather can improve a person's mental health and well⁃being, said Lahdenperä.
But there are signs of that in the animal kingdom, she said. Male animals seldom socialize with their own children, let alone grandchildren. “Males are usually focusing on producing their own children and aren't providing so much care,” Lahdenperä said.
