   What will power your house in the future?Nuclear, wind, or solar power?According toscientists at the Massachusetts Institute of Technology(MIT)in the US, it might beleaves—but artificial(人造的)ones.

    Natural leaves are able to change sunlight and water intoenergy. It is known as photosynthesis(光合作用). Nowresearchers have found a way to imitate this seemingly simple process.

    The artificial leaf developed by Daniel Nocera and hiscolleagues at MIT can be seen as a special silicon chip with catalysts(催化剂). Similar tonatural leaves, it can splitwater into hydrogen and oxygen when put into a bucket of water. The hydrogenand oxygen gases are then stored in a fuel cell, which usesthose two materials to produce electricity, located eitheron top of a house or beside the house.

Though the leaf is only about the shape of a poker card, scientistsclaimed that it is promising to be an inexpensive source of electricity indeveloping countries.“ One can imagine villages in India and Africa not longfrom now purchasing an affordable basic power system based on this technology, ”said Noceraat a conference of the American Chemical Society.

    The artificial leaf is not a new idea. The first artificial leafwas invented in 1997 but was too expensive and unstable for practical use. Thenew leaf, by contrast, is made ofcheap materials, easy to useand highly stable. In laboratory studies, Nocera showedthat an artificial leaf prototype(原型)could operatecontinuously for at least 45 hours without a drop in activity.

    The wonderful improvements come from Nocera's recent discoveryof several powerful, new andinexpensive catalysts. These catalysts make the energy transformation insidethe leaf more efficient with water and sunlight. Right now, the new leafis about 10 times more efficient at carrying out photosynthesis than a naturalone. Besides, the device canrun in whatever water is available;that is, it doesn'tneed pure water. This is important for some countries that don't have access topure water.

    With the goal to “make each home its own power station” and“give energy to the poor”, scientistsbelieve that the new technology could be widely used in developing countries, especially inIndia and rural China.

(1)、Which of the following orders correctly shows how the artificial leaf is used to produce electricity?

a.artificial leaves split water into hydrogen and oxygen

b.the hydrogen and oxygen gases are stored in a fuel cell

c.the artificial leaves are put in water

d.the fuel cell uses hydrogen and oxygen to produce electricity

A、c,b,a,d B、c,a,b,d C、b,c,a,d D、c,a,d,b
(2)、The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A、build up more power stations in the world B、provide cheaper energy for developing countries C、offer people in developing countries access to pure water D、gain a deeper understanding of the photosynthesis process
(3)、The main idea of this passage is ________.

A、an introduction to the history of artificial leaves B、an invention copying photosynthesis C、giving energy to the poor D、a mixture of water power and solar energy

    Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave and mighty (强大的) forces will come to your help.

    Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had jumped into deep water, forced by courage or circumstance (环境), I had always been able to swim until I got my feet on the ground again.

    Boldness means a decision to bite (咬) off more than you can eat. And there is nothing mysterious about the mighty forces. They are inner powers we have: energy, skill, sound judgment, creative ideas––even physical strength greater than most of us realize.

    Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself facing a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and crazily threw myself at that guy like a bullet (子弹) ––and stopped him cold.”

Boldness—a willingness to get yourself to the extreme—is not one that can be gained overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee (保证) of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

    So, always try to live a little bit beyond your abilities — and you'll find your abilities are greater than you ever dreamed.

    There was a time in the 1960's and 1970's when some people believed that coffee would replace tea as Britain's favourite drink, but that did not happen, and today, tea remains Britain's favourite drink.

    To say that the British are fond of tea is something of an understatement. From the Royal(皇室的) Family down to the homeless and the out-of-work, tea is more than just a pleasure. It is an important part of life!

    The popularity of tea in the United Kingdom has a long history. It was in 1657 that Thomas Garway, the owner of a coffee house, sold the first tea in London. The drink soon became popular as another choice besides coffee.

    In those days, however, tea was not something for anyone. For a century and a half, it remained an expensive drink. Many bosses served a cup of it to their workers in the middle of the morning, thus inventing a lasting British tradition, the “tea break”. But as a social drink outside the workplace, tea was served for the nobility(贵族) and for the growing middle classes. Among those who had the money for tea, it became very popular as a drink to be enjoyed in cafés and “tea gardens”.

    It was the 7th Duchess of Bedford who, in around 1800, started the popular “afternoon tea”, which took place at about four o'clock. At about the same time, the Earl of Sandwich popularized a new way of eating bread with something (e. g. jam) between them, and before long, a small meal at the end of the afternoon with tea and sandwiches had become part of a way of life.

    As tea became much cheaper during the nineteenth century, its popularity spread right through British society. In working-class households, it was served with the main meal of the day, eaten when workers returned home after a day's labour. This meal has become known as “high tea”.

    Today, tea can be drunk at any time of day. Most people in Britain drink tea for breakfast. The mid-morning “tea break” is an institution in British offices and factories. Later in the day, “afternoon tea” is still a way of life in the south of England and among the middle classes, while “high tea” has remained a tradition in the north of Britain.

    Finding a mountain goat resting high on a cliff(悬崖) might thrill many of the millions of tourists who visit Wyoming's Grand Teton National Park every year, but park officials say it might be time for the bearded animals to go.

    The problem, according to the park, is that Grand Teton's 100 or so mountain goats threaten about 80 bighorn sheep. The bighorn sheep numbered as many as 125 just a few years ago. The strong goats spread disease and compete with bighorn sheep for food. Unlike small-sized bighorn sheep, Grand Teton's mountain goats aren't native to the park. They were introduced to the park in the 1960s.

    Grand Teton spokeswoman Denise Germann said, “We've got a management responsibility to protect the native species. After hearing from the public on the proposal (建议) in January, park officials expect to decide as soon as mid-February on what to do about the mountain goats.”

    The goats are reproducing rapidly. Now might be the best time to reduce the animals before they're too many to bring under control, according to the Park Service.

    One wildlife biologist who studies bighorn sheep praised the proposal. Mountain goats' original habitat is nowhere close to where they've been introduced in the U.S. to provide hunting opportunities, said Rob Roy Ramey II, with Nederland, Colorado-based Wildlife Science International, Inc.

    Wildlife managers should get rid of mountain goats not only in Grand Teton but elsewhere to help struggling bighorn sheep, Ramey said. “Unfortunately, state wildlife agencies sell nonnative wildlife viewing opportunities to the public,” Ramey said. “This is not a zoo in the wilderness. It should really be for native wildlife.”
