Some wonderfully creative uses of X-rays have been in the world of art.But the most impressive one is to uncover what has been covered up.Details unfolded by an X-ray of a painting can ' t be seen any other way.For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas(帆布).These repairs cannot be seen just by looking at the painting.It takes an X-ray to discover where the repairs have been made.
An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery.If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original.If the brushstrokes (笔迹) , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy.
Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different.This is another way X-rays can be used to spot a forgery.A modern artist will try to make a forgery (伪造物) look hundreds of years old by painting dirty varnish(清漆)on it or by using artificial means to get the varnish to look cracked(破裂的).To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious.
It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it.Or artists would paint over others' work —it was their version of recycling.Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes.Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed.
What is the main purpose of the article?

A.To provide information to police who are looking for stolen art.
B.To persuade art dealers to check for fake copies before selling art.
C.To explain how modern technology can be applied in unique ways.
D.To help artists restore damaged artwork to its original appearance.

Scientists have long understood the key role that oceans play in controlling the Earth’s climate. Oceans cover 70 per cent of the surface of the globe and store a thousand times more heat than the atmosphere does. What’s newer is the understanding of how this key component(组成部分) of our climate system responds to global warming.
A brake on global warming—for now
One of the oceans’ most important climate functions is absorbing heat and carbon dioxide(CO2), one of the gases that causes global warming. Acting as something absorbing heat, the oceans have absorbed huge amounts of heat and CO2 in the last forty years.
Fujita explains, “the oceans are saving us from faster climate change—they are putting a brake on the climate system.”
“That’s the good news,” he adds. “The bad news is that the oceans only slow the atmospheric warming. Once the oceans come to balance with a greenhouse-gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter.” But where and how the oceans release this slowly increased heat is uncertain. And as the ocean stores heat, fragile(脆弱的) underwater ecosystems are struggling.
The most recent scientific report from the Intergovernmental Panel on Climate Change(IPCC) also notes with concern that the ocean is acidifying(酸化) because of increased absorption of atmospheric CO2. and thus causing a threat to shell-forming species. Sharp increase in CO2 levels will cause further acidification of the ocean.
Currents distributing heat
Another important role the oceans play is that of distributor(散布者). Oceans deliver heat and life-sustaining nutrition around the globe. Just as blood tube bring oxygen and nutrition to cells in the human body, the ocean’s currents carry oxygen, nutrients and heat throughout the Earth. The ocean distributes 25 to 50 per cent of energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern European a milder climate that it would normally have so far north. A change to the ocean’s circulation patterns could throw Europe into a colder period, even as the rest of the world is experiencing warmer temperatures.
We can infer from the passage that _______.

A.the oceans cause global warming B.the oceans stop global warming
C.the oceans release nutrients and heat D.the ocean ecosystems face more dangers

From the passage we can learn that ocean’s currents _______.

  1. produce oxygen and nutrients around
  2. absorb 25-50% of the energy from the sun
  3. distribute the atmosphere hotter
D. change the ocean’s circulation patterns
Which of the following are the results of the ocean absorbing heat and CO2?
a. It causes further acidification.
b. It makes the atmosphere hotter.
c. It balances the oceans with a green-house gas.
d. It affects shell-forming species.
e. It makes the oceans act as a heat sponge.
f. It controls the Earth’s climate.

A.a-c-f B.a-d-f C.b-d-e D.b-c-e

If the ocean’s circulation pattern changed, ______.

A.Asia would suffer a hotter climate.
B.Europe would become hotter
C.the rest of the world would become warmer.
D.the climate of Europe would become colder.

Shoppers throughout the West, wary(谨防的) of a double-dip recession(经济衰退), are still pinching their pennies. However, Chinese consumers are opening their wallets big time. According to Mckinsey, shop sales in China have grown by 25 per cent annually from 2007 to 2009. Consumer confidence is now at its highest point since 2007 and female shoppers are leading the way.
Chinese women saved just 24 per cent of their income, compared with 55 per cent in 2006, according to a recent study in the magazine Women of China. What’s more, three quarters of Chinese women say that they’re the ones who control the family purse strings, which means they are an “emerging powerhouse within the powerhouse” of China.
In the 1950s women contributed just 20 per cent of household income, which rose to about 40 per cent in the 1990s and then reached 50 per cent last year.
In a recent study of Chinese consumer behavior, Mckinsey found that women tend to shop more frequently than men, and spend more on personal-care products and food. Men, by contrast, tend to spend more of their income on gadgets(小玩意), drinks and alcohol, dining out, and socializing. They also tend to save for the bigger-ticket items, like cars and houses.
Chinese women make up an ever-growing small part of the market—up from 20 per cent a decade ago to 50 per cent last year. It’s estimated that in the next five years women will account for 55 per cent of the$9 billion market. “The future is female,” concludes a January HSBC report on special and expensive goods in China.
According to the passage, Chinese women ________.

A.save less of their income than before
B.are more cautious of spending their money
C.make as much money as men in the 1990s.
D.spend half income on expensive goods
