Even as we humans keep polluting the world. Nature somehow keeps finding a way to help correct our mistakes. First, there is a molecule(分子)that helps reduce global warming. Now, a team of Yale students may have discovered something equally amazing — plastic eating fungi(真菌).
Pestalotiopsis microspora(微孢子)is the only known fungus to be able to survive only on plastic. The plastic is so hard that it takes thousands of years to break down on its own.
The best part is that these fungi can do the job even in an oxygenless environment, which means that it could work perfectly even at the bottom of a landfill.
The discovery was the result of an effort between three Yale students who were part of the Rainforest Expedition and Laboratory Program, allowing a selected group of students to visit Ecuador’s rainforest and seek out fungi and bacteria that live inside plants without harming them, which could hold medical or scientific promise. The samples are then brought back to the University’s lab where they do wide testing to see if they are of any practical or scientific use.
In 2008, a student named Pria Anand gathered specimens for one purpose — to find a microbe that could eat plastic. That’s when she came across the Pestalotiopsis microspora. Though she did show the unbelievable characteristics of the fungi, she was unable to get the desired results by the time she graduated, in 2010.
Luckily for her Jonathan Russell, a 2011 graduating student, picked up right where she had left off. By combining her work with research performed by another of Pria’s classmates, Jeffery Huang, he was able to separate the enzyme(酶)in the fungus that is the most effective in breaking down plastic.
Hopefully, experts will take it up from here and make the project a reality and help reduce plastic!

While nature lovers across the world wish all humans to realize the significance of their natural surroundings, many Australians are turning caring for the environment into a way of life.
Julie Astonis, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia’s Brisbane in April, one can still watch colorful blooming (盛开的) flowers in Julie’s little garden, as she tells that in her community, “Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden.
“Gardening is the most popular club in our community,” she says. “A lot of retired people don’t just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year.”
Talking about her people’s sense of care for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog’s waste. “In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass,” says Julie with a smile.“Taking care of the dog’s waste can a1so help to develop children’s sense of responsibility!”
As to protecting water resources, the Australian government has made strict rules for families. Julie says, “We certainly would not use tap water to water the flowers!” She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, connect the water tank with their toilets.
1.From the first three paragraphs we learn that .
A. gardening is popular in most part of Australia

The real point of human nature lies in the social bonds that we make through family, friendships, professional associations and local communities. These bonds produce a sense of common purpose and values, in which groups of people seek hard and enjoy together the things that are for the common good: a sound education, a pleasant environment to live in, a healthy population. This is what the heart of the gift economy (经济) is.
In the past, American companies operating in Japan found it difficult to attract Japanese people, even though, compared with Japanese employers, they offered more generous wages, shorter work hours and better promotion chances. But these were traditionally not so important to the employees, who did not think of their services as being ‘bought’. Rather, they felt they were entering into a long-term—“gift exchange” —relationship with their employer, which was of mutual (相互) benefit.
This relationship had many aspects. At its most basic it related the simple exchange of physical gifts. For example, if the employee got married, the company sent a gift. Another company gift which is popular among Japanese employees is the yearly company vacation. On these organized weekends co-workers share dormitories, eat together and visit the same attractions, largely at the company’s expense. For their part, the main gift given by the employees to their company is their hard work and this is why each Japanese employee gives such great attention to accuracy, and quality in their work. Even the simplest tasks are carried out with extraordinary care.
Now, neighborhood groups use online networks to share tools and skills. Someone who needs a long ladder to repair their roof does not need to go out and buy one; they simply put a message up on the neighborhood discussion board and soon a neighbor will offer theirs. Via the Internet, knowledge and advice can be shared on almost everything, from how a nuclear reactor works to how to plan your holiday. The gift economy is going through a booming time.
1.What is the key point of the gift economy?
A.People’s working hard. B.People’s similar social status.
C.Sharing social interests. D.Accepting social bonds.
2.Why did the Japanese show little interest in American companies?
A.The companies offered them low salaries.
B.They were difficult to get a better position.
C.The companies provided shorter vacations.
D.They didn’t want to sell their services.
3.What does the yearly company vacation inspire Japanese employees to do?
A.Contribute themselves to the company.
B.Exchange physical gifts with each other.
C.Spend less money while talking vacations.
D.Organize more effective weekend parties.
4.What can we infer about the gift economy from the last paragraph?
A.It is changing the Internet services. B.It benefits greatly from the Internet.
C.It is better accepted on the Internet. D.It booms the Internet development.

高三英语单项填空中等难度题查看答案及解析
Even if we have an extremely healthy diet and lifestyle, the human body is programmed to wear out at a maximum of about 120 years, and usually less. We all have a biological clock inside us which determines the moment when our organs cease to function properly. This is because our cells have stopped renewing themselves and our body can no longer repair itself. This is also the moment when we are more likely to begin to suffer from the diseases of old age such as arthritis and Alzheimer’s. However, rapid advances in DNA research are beginning to throw light on the secrets of the ageing process. By the end of this century we could literally have the power of life over death.
Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to live indefinitely. The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing.
Another new area of research involves the oxidation（氧化） theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young.
Perhaps the most immediate advance we are likely to see in the battle to halt（停止）the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing injured bones or even organs like livers and kidneys with ones “grown” in laboratories. By 2050 perhaps every organ in the body, except the brain, will have become commercially available. Recent experiments also show that it may one day be possible to “grow” new organs inside our body to replace worn-out ones, something which lizards and alligators already do.
Suddenly immortality（不死，不朽） seems within reach. We can begin to imagine a future where we are born, we grow to maturity, but we never grow old and die. But do we really want to live forever?
1. When all humans reach a certain age, ________.
A．they suffer the effects of their diet and lifestyle
B．the organs stop to perform appropriately
C．their cells continue to renew themselves
D．they develop arthritis and Alzheimer’s
2. The purpose of showing the case of alligators is to prove ________.
A．alligators are in danger in the wild because of the threat from man, pollution and other animals
B．it is widely accepted that humans have a fixed lifespan
C．there exists an age gene which may control ageing
D．the age gene damages the body
3.The underlined phrase “live indefinitely” in Paragraph 2 probably mean ________.
A．live for a period of time without a fixed end
B．live without a clear aim
C．live in an uncertain way
D．live without being fully grown
4.It can be inferred from Paragraph 4 that ________.
A．by 2050 we might have most of our worn-out organs replaced with new ones commercially
B．never can the ageing process be avoided
C．livers and kidneys are sure to be grown in laboratories by the year 2020
D．lizards and alligators grow new organs inside their body to replace worn-out ones
5. What is the main topic of this passage?
A．DNA researches show how our cells renew themselves.
B．Anti-oxidants are likely to play an important part in keeping people young.
C．How our biological clock works?
D．Eternal（永恒的） youth: new developments in anti-ageing research.
6.By saying “But do we really want to live forever”, the author may probably mean ________.
A．a future where we are born, we grow to maturity, but we never grow old and die is on its way
B．he is uncertain whether we can live forever
C．it remains to be seen whether immortality is a blessing or a curse
D．immortality is no longer a dream
