A new study by Harvard University adds weight to the idea     1     being selfless can help us live longer. Selfless     2     (act) such as volunteering help us live longer, according to the new research. A study of 13,000 adults in the US found that people over the age of 50, who volunteer for two hours a week have     3     (little) chance of developing disease compared to those who don’t.

“Our results how that volunteering among older adults doesn’t just strengthen communities, but     4     (enrich) our own lives by strengthening our bonds to others, helping us feel a sense of purpose, and protecting us     5     feelings of loneliness, depression and hopelessness,” said the co-author of the study, Dr Eric Kim of Harvard. Loneliness could be as damaging to a person’s health     6     smoking 15 cigarettes per day. “If you are able to do so, you not only can help to heal and repair     7     world, but you can help yourself as well,” he said.

The Harvard study will increase the motivation to develop public health interventions (干预)     8     (base) on volunteering, which is what the UK-based charity Volunteering Matters campaigns for. “Some cities     9     (be) pioneering this idea several years ago, and I hope we have the willingness     10     (do) so in a post -COVID-19 society as well. ”said Dr Kim.

3 . News that dolphins form friendships may not come as much of a surprise to anyone paying attention to the animal world.     1    . They form their friendships with those that have a common interest.

For the research, scientists study the lives of a population of bottlenose dolphins in the Western Australian World Heritage area of Shark Bay. These dolphins are unique in their use of marine sponges (海绵体) as tools to find food.     2    . The method is taught by their mothers and helps the “spongers”, as the ones who do it are called, find food in deeper water. Both male and female dolphins can be spongers, but the study focused just on males.

    3    . But for the study, they selected a group of 37 male dolphins, including 13 spongers and 24 non-spongers. They found that the spongers spent more time with other spongers and that the bonds were based on similar foraging (觅食) techniques and not relatedness or other factors.

    4    , so it was long thought to invest time informing close bonds with other males. This study suggests that male dolphins form social bonds based on shared interests. Interestingly, while male spongers spent more time looking for food than non-spongers, both groups spent an equal amount of time socializing.

“Male dolphins in Shark Bay exhibit fascinating strong social bonds.     5    . They are critical to each male’s mating success. We were very excited to discover alliances of spongers, dolphins forming close friendships with others with similar traits,” says Dr. Simon Allen, the leading author of the study at the University of Zurich.

A．The method satisfies the needs of male dolphins

B．Foraging with a sponge is a time-consuming activity

C．The researchers used the data from 124 male dolphins

D．These strong bonds between males can last for decades

E．Male dolphins spend a lot less time resting and travelling

F．They are the only ones to ever have been observed doing this

G．But a new study throws light on how much they do it like we do

4 . Scientists and engineers are preparing for possible travel into interstellar (星际的) space, the area in between stars, in the distant future. A new report examines the possible problem of changes in language on long space trips. Two American researchers have explored one possible problem with such travel. They considered the possibility that changes in human language could develop overtime and lead to major communication problems with people on Earth.

The language experts are professors Andrew McKenzie from the University of Kansas, and Jeffrey Punske of Southern Illinois University. The two recently published a paper, which considers very long trips necessary to reach interstellar space, estimated to be about 18 billion kilometers from Earth. It also examines the possibility of future colonization (殖民地的开拓) of distant stars.

Languages naturally change as communities grow more isolated from each other, the researchers note in the paper. The long isolation of a community could lead to enough differences in language to make it impossible for community members back home to understand. “If you’re on this spaceship for 10 generations, new concepts and social issues will emerge, and people will create ways of talking about them,” McKenzie said in a statement. Such vocabulary would become specific to only that spaceship.

“People on Earth might never know about these words, unless there’s a reason to tell them. And the further away you get, the less you’re going to talk to people back home,” McKenzie said. The researchers noted that in addition to new words being used, the language of people traveling on spaceships and living in colonies would experience many other changes. For example, the sounds of different letters would likely change overtime, affecting not only individual words, but the whole “grammatical system”, the paper states.

Major changes in word and sentence structure could also create systematic language barriers overtime, the researchers said. “Given more time, new grammatical forms can completely replace current ones,” McKenzie said.

5 . A study by the University College London (UCL) has shown that staring at long wavelength light for three minutes every day can significantly improve vision in those aged 40 and above.

Cells in the retina (视网膜) of the eye begin to worsen at around 40 years of age. According to the researchers, the pace of this ageing is caused partly by a decline in the cell mitochondria, whose role is to produce energy and boost cell function. Professor Glen Jeffery of the UCL Institute of Ophthalmology said, “As you age, your visual system declines significantly, particularly once over 40. Your retinal sensitivity and your color vision are both gradually undermined (破坏), and with an ageing population, this is an increasingly important issue.”

To try to stop or change this decline, the researchers sought to restart the retina’s ageing cells with short bursts of long-wave light. They recruited 24 people, aged between 28 and 72, who had no ocular (眼睛的) disease to take part in their study. The participants were given special LED torches to take home and were asked to gaze into its deep red 670nm light beam for three minutes a day for two weeks, They were then retested for color vision as well as for vision at low light levels. The ability to detect colors improved by up to 20% in some people aged around 40 and over. But the effect was not seen in younger individuals who were aged below 40.

Scientists believe the discovery could pave the way for new eye therapies that are affordable and can be done by the patient at home. Prof. Jeffery said, “Using simple brief exposure to light wavelengths that recharge the energy system which has declined in the retina cells, is rather like recharging a battery.   The technology is simple, safe and very promising.

1. What does Jeffery express in paragraph 2?

A．Age affects the visual system.	B．It’s necessary to protect eyesight.
C．The ageing population is now serious.	D．Weak color vision is mainly caused by ageing.

B．It aims to improve the vision of the elderly.

C．People’s eyesight can be improved by long-wave light.

D．Participants over 40 benefited more from the study.

3. What is the significance of this discovery?

A．It helps people save more electricity.	B．It’s practical and has medical value.
C．It saves many aged people with ocular diseases.	D．It’s the most effective treatment for vision loss.

4. Where is this text most likely from?

A．A travel guidebook.

B．A popular novel.

C．A fashion magazine.

D．A health journal.

6 . I was trained as a gymnast in Hunan, China, in the 1970s. The government wanted to transfer (转学) me to a school for athletes while my parents wanted me to become an engineer, because they firmly believed there was only one sure way to happiness: a safe and well-paid job. But my dream was to become a Chinese opera singer. Although I tried everything I could to go to opera school, I knew I was too old to be trained and my dream would never come true.

But that’s so unfair. So I was determined to find another calling — books. I satisfied my hunger for parental advice from the Fu Lei’s Family Letters by Fu Lei and Zhu Meifu, found my role model of an independent woman from Jane Eyre, learned to be efficient from Cheaper by the Dozen, and inspired myself to study abroad after reading Complete Works of Sanmao and Lessons from History.

I came to the U. S. in 1995 where I started comparative reading. Comparing and contrasting give scholars a more complete understanding of a topic. So I thought, well, if comparative reading works for research, why not do it in daily life too? So I started reading books in pairs. They can be about people who are involved in the same event — Benjamin Franklin by Walter Isaacson and John Adams by David McCullough, for example, or friends with shared experiences. I also compare the same stories in different genres or similar stories from different cultures, as Joseph Campbell did in his wonderful book The Power of Myth.

Books have given me a magic portal (入口) to connect with people of the past and the present. I have come to believe that coming true is not the only purpose of a dream. Its most important purpose is to get us in touch with where dreams come from, where passion comes from and where happiness comes from. Even a shattered (遭受极大打击的) dream can do that for you. So may books be always with you.

1. What’s the purpose of paragraph 1?

A．To provide background information.	B．To list some examples.
C．To make a comparison.	D．To summarize the paragraphs below.

2. From which book did the author get the motivation to study abroad?

A．Fu Lei’s Family Letters.	B．Jane Eyre.
C．Cheaper by the Dozen.	D．Complete Works of Sanmao.

3. What is paragraph 3 mainly about?

A．The future of comparative reading.

B．The concept of comparative reading.

C．The writer’s experiences of comparative reading.

D．The writer’s achievements of comparative reading.

4. What is the best title for the text?

A．How I Chase My Dreams	B．How Books Open My Mind
C．Why I Am Keen on Comparative Reading	D．Why a Shattered Dream Changes My Life

7 . From prehistoric (史前的) cave paintings to modern-day dog shows, humans’ love and fascination for animals has long remained. The following projects show you how humans are working to create a brighter future for animals.

Big Cats Initiative

This has the primary goal of stopping the decline in the population of big cats worldwide since 2009. In Africa, this means ensuring the monitoring and protection of species like lions and cheetahs, whose numbers have declined sharply over the last century. With the Initiative’s help, these species will continue to live in their natural habits, safe from illegal hunting, environmental degradation (恶化), and other human influences. Find it on: Explore Kruger National Park.

Polar Bears International

Climate change has threatened the world’s polar bear populations: As the planet warms, these creatures risk losing more of their icy habitat than ever before. This project works to reduce greenhouse gas emissions that cause the melting of the Arctic sea ice upon which polar bears depend, and to raise awareness about the plight (困境) of this beautiful animal. Find it on: Canadian Polar Bear Experience.

Vembanad Wetlands Conservation Program

Since 2005, the program has worked to protect the habitat of plants and animals in the wetlands of Vembanad Lake in India. The organization also teaches and monitors sustainable fishing practices there; travelers will learn from fishermen how fishing practices are carried out in a way that does no damage to these important waters. Find it on: Iconic India.

Sea Turtle Conservancy

Sea turtles depend on seagrasses. When these grasses die, the turtles a replaced at serious risk. This has a cyclical effect: seagrasses, like regular grass on land, depend on regular “mowing” to continue growing, and without turtles to feed on it, the grass itself stops thriving, which threatens hundreds of other species who use seagrasses for shelter. Find it on: Explore Costa Rica.

1. Why was Big Cats Initiative setup?

A．To prevent big cats from illness	B．To monitor the population of big cats.
C．To protect the endangered big cats.	D．To stop the environment from worsening.
