Up to the present, many scientists have made great contributions to the understanding of the universe.
One of them is Albert Einstein, a German physicist, who revolutionized our concepts of space and time with his theories of relativity. In 1905 Einstein published his special theory of relativity. The foundation of the theory is the observation that light moves at a constant speed as measured by all observers, whatever its state of motion. One consequence is that measurements of distance and time are not absolute quantities but very relative to the motion of an observer. Another is that energy(E) can be converted into mass(m), and vice versa, according to the formula E=mc2 ,where c is the speed of light. Ten years later, Einstein’s general theory of relativity extended this work to include acceleration and gravity — stating that the two are equivalent. Einstein showed that gravity is actually the warping of space by matter. One consequence is that light will follow a curved path when it passes a massive body. Observations of a small apparent shift in the positions of stars near the sun during a solar eclipse in 1919 showed that the theory was correct.
General relativity was later used to interpret Edwin Hubble’s discovery of the expanding universe. Edwin Hubble discovered a universe of galaxies outside the Milky Way and showed that the entire universe is expanding. In the early 20th century, most astronomers believed that the universe did not extend beyond our Milk Way galaxy. Then in the early 1920s, Hubble pointed the largest telescope in the world (on Mt. Wilson in California) at the mysterious Andromeda nebula. He recognized individual stars within the "nebula" and concluded that it was not a cloud of interstellar gas within our Milky Way, but an entire galaxy very far away. Suddenly, the universe was far larger than most astronomers had imagined. Hubble continued to find galaxies at greater and greater distances. He developed the system for classifying galaxies by their structure, which is still used today. Hubble also discovered that the distant galaxies are moving away from each other and the greater the distance between two galaxies, the faster they are moving away. This simple proportionality between the distance and the speed of galaxies moving away from each other, set forth in 1929, is now known as Hubble’s law. It shows that the universe is expanding.
When we talk about early sky gazers, we can not forget the Danish astronomer Tycho Brahe Before the invention of the telescope, Tycho Brahe revolutionized astronomy by establishing the importance of accurate observations. He invented an improved sextant and used it to make precise observations of the positions of stars and planets.
Brahe completely recalculated Ptolemy’s astronomical tables, which contained many errors, and catalogued over one thousand stars during his lifetime He built Europe’s first observatory and taught the art of observation to a generation of astronomers. In 1572 Brahe made careful observations of a "new star" (actually a supernova) that appeared suddenly in the constellation Cassiopeia He showed that the object was not in the Earth’s atmosphere but was actually beyond the orbit of the moon. This discredited the prevailing theory that the heavens are static and unchanging.
Armed with Tycho Brahe’s very accurate observations of the planets and his own painstaking measurements, Johannes Kepler discovered what we now call Kepler’s laws of planetary motion. These three laws precisely describe the motions of the planets around the sun.
Kepler’s first law states that planets move in elliptical orbits around the sun. This overturned the ancient dogma that the planets move in perfect circles. His second law describes how a planet travels faster in its orbit when it is closer to the sun. The third law describes how the orbital periods of the planets increase with the size of their orbits. Kepler’s laws were based on the Copernican view of a heliocentric universe Newton relied on them when he developed his more general law of universal gravitation.

In ancient times, people believed that planets traveled ().

A
Rotherhithe Rotherhithe may be most famous for its congested tunnel but many young buyers are warming to its riverside charms.
It is still much cheaper than its waterside neighbors. The housing stock is predominately 1980s flats, many arranged in cul-de-sacs(死胡同) and closes around Surrey Quays Road.
The unpopular architecture has led to the area being called the Milton Keynes of London but properties are spacious and unfashionable style has kept prices down.
Paul Mitchell, of estate agents Alex Neil, says, "There is precious little period property, but you will get far more for your money here than a Victorian house with lots of original features down the road in Bermondsey. "
Surry Quays shopping center provides all the amenities of a high street but the area is lacking in fun. However, Southwark Council is in talks to develop the "night time economy" which could well lead to an increase in bars and restaurants to cater for the growing number of young professional residents.
"It is possible to get a good three-bedroom house in Rotherhithe for 280000," says Wumine Jordan Robinson, of agents Burwood Marsh. "About eight minutes’ walk from the Jubilee Line which will have you in Bond Street in 15 minutes. There are not that many areas in London where that is possible."
B
Barnes Barnes sits just across the river from Hammersmith in southwest London, but it could not be more different from the noise and bustle of the opposite bank.
It has been called one of the last true London "villages" with happy residents keeping its old school charms quiet from nosey outsiders and potential developers.
Being by the river and predominately residential gives Barnes an attractively lazy vibe. It has a traditional village green complete with idyllic duck pond and quaint pub. The high street is about as far from the Pound Shop and Primark ambience of its neighbors as is possible.
But buying into Barnes is not cheap. "Family houses are snapped up incredibly quickly," claims Chris Carney, sales negotiator at Boileaus estate agents. "It is very hard to get properties of this size, with outside space so close to London, which is why they are expensive."
Large detached Victorian houses on the two main roads, Casttenau and Lonsdale, normally have between five and seven bedrooms, gardens of 120 ft and off-street parking. These sell for anything between £2 million and £5 million.
By the village green there are rows of immaculate terraced houses on a number of streets that run off Church and Station roads, and four-bedroom houses of this kind sell for around £1 million.
C
Willesden Green Willesden Green has both suffered and benefited from its famous neighbors. Despite its growing popularity, the area remains interesting and multi-cultural, injecting a little bit of soul into what could otherwise become just another yuppie backwater.
"Willesden Green has a diverse range of properties from 1930s semi-detached houses to large Victorian properties and new-builds which attract all kinds of buyers," says Richard Chiti, sales manager at estate agents Ellis & Co.
"The roads bordering West Hampstead are popular, as they are wide, tree-lined streets with sizeable family houses. Properties in and around Dobree Road, which lead down to Kensal Rise, are also in high demand."
Estate agents and residents agree that the area used to be regarded as dangerous and undesirable, but this has changed over the last decade. It’s popular because it is still affordable, although prices have rocketed over the last year.
D
King’s Cross King’s Cross used to be renowned for problems including drugs, prostitution and street crime but a £2 billion regeneration programme should help the area lose its seedy reputation.
The project includes a new Eurostar terminal opening this year and a spruced-up tube station, alongside hundreds of new homes, offices and leisure facilities set to be completed in 2015. Such development has had a predictable effect on house prices.
"There are a lot more amenities now, such as supermarkets, cafes and bars, and the issue people used to have with safety a few years ago has disappeared. " By the canal basin, new-built flats and luxury warehouse conversions from the bulk of property, and at the top end of the market there are stunning penthouses available with views across London.
Much of the new development is centered on the back of the station, off York way, and flats are being sold to eager buyers off plan.
The older properties are mainly mid-Victorian terraces around Caledonian Road and the streets heading towards Angel, and ex-local authority blocks where it is possible to pick up a two-bedroom refurnished flat for under £250000.
Smith adds, "Investment-wise, King’s Cross is a good bet. There is a big rental market here and prices will go up. There are still cheaper properties available, one- to two-bedroom flats in Victorian conversions, or ex-council properties. But people are holding on to them for dear life in the hope they will go up in value. If you find one, it is worth investing in.\

International investors seem incapable of ending their love affair with the dollar. America’s economy has slowed sharply this year, yet its currency has risen to a 15-year high in trade-weighted terms. Against the euro the dollar touched $ 0.88—8% higher than in early January an close to the level at which the European Central Bank and the Federal Reserve jointly intervened to prop up the European currency last September. Why is the euro looking sickly
There are plenty of theories. One is that the markets do not trust the ECB: the euro-area economies are not immune to America’s downturn, yet the central bank still seems more concerned with fighting inflation than with supporting growth.
66. ______
Most economists reckon that the euro is undervalued and expect a rebound over the next year. One of the most optimistic is Goldman Sachs, which is predicting a rate of $1.22 in 12 months.
67. ______
He has found that, over the past decade, movements in the real exchange rate of the euro against the dollar have closely reflected the difference between productivity growth in the euro area and in America. When productivity growth in America has been faster than in Europe — as it was in most of the late 1990s — the euro falls, and vice versa.
68. ______
Mr Owen uses monthly data for productivity growth in manufacturing, a good proxy for the traded-goods sector. Using annual productivity data for the whole economy (which are available over a longer period., the broad relationship between the exchange rate and relative productivity growth in America and Europe seems to have persisted for most of the past 30 years.
Mr Owen reckons that, in the short term, America’s downturn will reduce the productivity gap between America and the euro area — and so boost the euro.
69. ______
Only if the downturn completely kills the belief in America’s new paradigm, and its productivity growth plummets, will the euro be able to rebound more permanently.
The strength of the dollar this year does indeed seem to hinge on a belief among investors that America’s slowdown will be brief, and that in the longer run America remains the best place in which to invest. But they may be underestimating the potential for productivity gains in Europe, as the single currency boosts competition and encourages firms to exploit economies of scale through mergers and acquisitions. The adoption of more flexible working practices in many countries should also help to improve productivity.
Studies in America suggest that the bulk of its productivity gains from information technology come from the use of IT rather than from its production.
70. ______
A. So the euro area, too, should start to enjoy productivity gains over the next decade, as it makes full use of IT. If you believe that Europe really is starting to change, buy euros. If not, stick with the darling dollar.
B. This is exactly what economic theory would predict: Countries with faster productivity growth in the traded-goods sector should see rising real exchange rates.
C. Some euro-skeptics worry that the expanding power of the European Union will eventually lead to the merger of today’s European countries into one new country. They believe that possibility becomes stronger if Britain joins the euro. But pro-euro activist Nick Canning says such fears are unfounded.
D. Another more plausible explanation is that, in an uncertain global economic climate, the dollar has resumed its traditional role as a safe-haven currency.
E. But an analysis by David Owen, an economist at Dresdner Kleinwort Wasserstein, gives pause for thought.
F. But in the long term, he expects productivity growth to remain faster in America — in which case, a sustained rise in the euro is unlikely over the next few years.

Many things make people think artists are weird. But the weirdest may be this: artists’ only job is to explore emotions, and yet they choose to focus on the ones that feel bad.
This wasn’t always so. The earliest forms of art, like painting and music, are those best suited for expressing joy. But somewhere in the 19th century onward, more artists began seeing happiness as meaningless, phony or, worst of all, boring, as we went from Wordsworth’s daffodils to Baudelaire’s flowers of evil.
You could argue that art became more skeptical of happiness because modern times have seen so much misery. But it’s not as if earlier times didn’t know perpetual war, disaster and the massacre of innocents. The reason, in fact, may be just the opposite: there is too much damn happiness in the world today.
After all, what is the one modern form of expression almost completely dedicated to depicting happiness Advertising. The rise of anti-happy art almost exactly tracks the emergence of mass media, and with it, a commercial culture in which happiness is not just an ideal but an ideology.
People in earlier eras were surrounded by reminders of misery. They worked until exhausted, lived with few protections and died young. In the West, before mass communication and literacy, the most powerful mass medium was the church, which reminded worshippers that their souls were in danger and that they would someday be meat for worms. Given all this, they did not exactly need their art to be a bummer too.
Today the messages the average Westerner is bombarded with are not religious but commercial, and forever happy Fast-food eaters, news anchors, text messengers, all smiling, smiling, smiling. Our magazines feature beaming celebrities and happy families in perfect homes. And since these messages have an agenda — to lure us to open our wallets — they make the very idea of happiness seem unreliable "Celebrate!" commanded the ads for the arthritis drug Celebrex, before we found out it could increase the risk of heart attacks.
But what we forget — what our economy depends on us forgetting — is that happiness is more than pleasure without pain. The things that bring the greatest joy carry the greatest potential for loss and disappointment. Today, surrounded by promises of easy happiness, we need art to tell us, as religion once did, Memento mori: remember that you will die, that everything ends, and that happiness comes not in denying this but in living with it. It’s a message even more bitter than a clove cigarette, yet, somehow, a breath of fresh air.

Which of the following is true of the text().

A. Religion once functioned as a reminder of misery.
B. Art provides a balance between expectation and reality.
C. People feel disappointed at the realities of modern society.
D. Mass media are disinclined to cover disasters and deaths.

A new study from the Center for Information and Research on Civic Learning and Engagement (CIRCLE) at Tufts University shows that today’s youth vote in larger numbers than previous generations, and a 2008 study from the Center for American Progress adds that increasing numbers of young voters and activists support traditionally liberal causes. But there’s no easy way to see what those figures mean in real life. During the presidential campaign, Barack Obama assembled a racially and ideologically diverse coalition with his message of hope and change; as the reality of life under a new administration settles in, some of those supporters might become disillusioned. As the nation moves further into the Obama presidency, will politically engaged young people continue to support the president and his agenda, or will they gradually drift away
The writers of Generation O (short for Obama), a new Newsweek blog that seeks to chronicle the lives of a group of young Obama supporters, want to answer that question. For the next three months, Michelle Kremer and 11 other Obama supporters, ages 19 to 34, will blog about life across mainstream America, with one twist: by tying all of their ideas and experiences to the new president and his administration, the bloggers will try to start a conversation about what it means to be young and politically active in America today. Malena Amusa, a 2t-year-old writer and dancer from St. Louis sees the project as a way to preserve history as it happens. Amusa, who is traveling to India this spring to finish a book, then to Senegal to teach English, has ongoing conversations with her friends about how the Obama presidency has changed their daily lives and hopes to put some of those ideas, along with her global perspective, into her posts. She’s excited because, as she puts it, "I don’t have to wait (until) 15 years from now" to make sense of the world.
Henry Flores, a political-science professor at St. Mary’s University, credits this younger generation’s political strength to their embrace of technology. "(The Internet) exposes them to more thinking," he says, "and groups that are like-minded in different parts of the country start to come together. " That’s exactly what the Generation O bloggers are hoping to do. The result could be a group of young people that, like their boomer parents, grows up with a strong sense of purpose and sheds the image of apathy they’ve inherited from Generation X (20世纪60年代后期和70年代出生的美国人). It’s no small challenge for a blog run by a group of ordinary — if ambitious — young people, but the members of Generation O are up to the task.

What can we infer from the passage about Generation X().

A. They are politically conservative.
B. They reject conventional values.
C. They dare to take up challenges.
D. They are indifferent to politics.
