    The effects of coffee consumption on health have long been a subject of conflict and uncertainty.Since the 1980s,some have spoken out against coffee as harmful to health,while others have welcomed coffee for its supposed benefits to health.

    According to a scientific report,mild coffee consumption,three to five cups per day,can he taken as a healthy dietary pattern,along with other healthful behaviors.The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson's disease.

    According to Dr.Donald Hensrud of Mayo Clinic,high consumption of coffee has health risks.Dr.Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body.Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.

    According to conclusions from a recent study led by Dr.Gregory Marcus,a doctor from the University of California San Francisco,daily moderate consumption of caffeine,less than 4 cups,is not associated with these issues.

    Until the scientific community reaches a general agreement on the effects of coffee consumption on human health,it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.

    When informed of these possible health benefits and harms of drinking coffee,Harwood,a high school student stated,"Even though there might be some negative effects of drinking coffee,for the most part,coffee drinking sounds good for health.Not to mention I need coffee to stay awake."

(1)、What is the people's attitude towards the effects of coffee on health according to Paragraph 1?
A、Disapproving. B、Tolerant. C、Doubtful. D、Mixed.
(2)、What does the underlined word "moderate" in Paragraph 4 probably mean?
A、Personal. B、Slight. C、Reasonable. D、Heavy.

    Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.

    Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.

    But others are doubtful about the link between happiness and growing older.

    "The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.

    In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.

    Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago's Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.

 Despite the conflicting findings about aging and happiness, the good news is that there doesn't appear to be a limit to how much happiness one can achieve in one's life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”

    Astronauts in the space stations for long missions often work very long days. Tasks are scheduled(安排) so tightly that break times are often used to finish the day's work. It's especially hard for long missions on the International Space Station (ISS). ISS crew members usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, Internet phone and through private video meetings.

    While astronauts cannot go to a baseball game or a movie in space, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crew member put together a collection of family photos, messages, videos and reading materials for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. Today, the Internet can be used on the ISS, giving astronauts the chance to do some “web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

    Many astronauts say that one of the most relaxing things to do in space is to look out of the window and stare at the universe and the Earth's vast land mass and oceans.

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize — which is often referred to as the Nobel Prize in architecture —on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements.

    Wang's works show a deep understanding of modern architecture and traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

    "Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created, "he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are," said Wang.

    The study of traditions should be combined, with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.

Plastic-Eating Worms

    Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场),and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.

    Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass--apparently broken down by enzymes(酶)from the worms' stomachs. Their findings were published in Current Biology in 2017.

    Federica Bertocchini, co-author of the study, says the worms' ability to break down their everyday food-beeswax--also allows them to break down plastic "Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, "she explains. "The wax worm evolved a method or system to break this bond. "

    Jennifer Debruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?

    Bertocchini agrees and hopes her team's findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process-not simply "millions of worms thrown on top of the plastic."

Choose the one that fits best according to the information given in the passage you have just read.

What is a TEDx event?

TEDx brings the spirit of TED's mission of "ideas worth spreading" to local communities around the globe. A TEDx event is a local gathering where live TED-like talks and videos previously recorded at TED conferences are shared with a community. TEDx events are fully planned and coordinated independently, on a community-by-community basis. All TEDx events present multiple issues and a diversity of voices from many disciplines. After all, what's the fun without a little variety?

If you want to organize a TEDx event, you'll need to apply for a TEDx license. No one is qualified to organize an event without being granted a license by TED.

So you want to organize a TEDx event?

Before you start you should know the TEDx rules, which are non-negotiable and mandatory.

General rules

* We value and welcome young organizers, but if you're under 18 years old, you must be supervised by an adult. TED doesn't grant licenses to individuals associated with controversial or extremist organizations.

* TED allocates one location-based license series per application. You must live in the city for which you are applying for a license. Your TEDx event must happen in the city for which you received the license.

* Your event must maintain the spirit of TED itself: focused on the power of ideas to change attitudes or lives. Your event may not exceed (超过) one day in length.

* Up to 100 individuals may attend your event. Only individuals who have attended an official TED conference may organize an event with more than 100 attendees. Having attended one or multiple TEDx events or TEDWomen does not qualify you to host an event for more than 100 guests.

* TEDx events are named after locations, such as cities, neighborhoods, streets etc., and aim to serve that named community. Event names must comply with the guideline laid out in naming your event.

Special attentions

※ A TEDx event is not a platform for professional speakers, such as motivational speakers and professional life coaches. Its purpose is to give a platform to those who don't often have one.

※ A TEDx event cannot be used to raise money, not even for a charity.

※ A TEDx event can't be co-branded with an institution except under specific license types – for a college or university, or for internal events (for corporations and organizations).

※ TEDx events may not be used to promote spiritual or religious beliefs, commercial products or any kind of political agenda.

※ Every TEDx event either shows only TED Talk videos to its audience, or shows both TED Talk videos and live speakers from the community. For events less than half a day in length, two TED Talks videos are required to be shown. For longer events, 25% of the total number of talks must be official TED Talk videos.
