Buster Brown was a thief-and a good one，too，he thought . He’d never been caught by the police because he never took chances． He was always prepared for any unforeseen event or emergency.
Confidently，he stood outside the house of his intended victim(受害者)and read the sign on the front gate of the house．“Don't worry about the dog—be aware of the owner!”it said．Buster smiled and found his way in．
The house looked quite normal outside，but inside it was very exotic with fascinating objects on display．As he began putting them into his bag，a dog came into the room．It stopped when it saw Buster，then wagged its tail madly and went over to him，licking his outstretched hand．
"Good boy，”Buster whispered． “What a great guard dog you are—trying to lick me to death.”
Satisfied he'd made friends with the dog，Bluster began to wander round the house，choosing items to put in his bag．His skilled eye picked out only the best antiques(古董)：a pair of silver candleholders，a silver tea-and-coffee service，etc．．His new friend，the dog，sat and watched，as if wondering what was happening．
“Well，boy，”Buster whispered，finally．“That might do．Any more and I won't be able to carry it!”He swung the heavy bag onto his shoulders, just as the lights came on, nearly blinding him. He shielded his eyes with his hand.
"You're a very silly person," the figure(身影) in the doorway said. As the man came closer, Buster could see he was well dressed. His face seemed familiar, but Buster couldn't quite be sure of the place where he had seen him before.
"You should have taken more notice of the sign outside," the man rasped. "I knew about this attempted robbery last week and I also know you will end up behind bars for 20 years. Fancy trying to rob the house of the world's greatest fortune-teller(算命先生)!"

First the ground shook in Haiti, then Chile and Turkey. The earthquakes keep coming hard and fast this year, causing people to wonder if something evil (邪恶的) is happening underfoot. It’s not.
While it may seem as if there are more earthquakes occurring, there really aren’t. The problem is what’s happening above ground, not underground, experts say. More people are moving into big cities that happen to be built in quake zones, and they’re rapidly putting up buildings that can’t withstand (经受) earthquakes, scientists believe. And around-the-clock news coverage (报道) and better earthquake monitoring(监测) make it seem as if earthquakes are ever-present.
“I can definitely tell you that the world is not coming to an end,” said Bob Holdsworth, an expert in tectonics (筑造学) at Durharn University in the UK.
A 7.0 magnitude quake in January killed more than 230,000 people in Haiti. Last month, an 8.8 magnitude quake--- the fifth-strongest since 1900—killed more than 900 people in Chile. And two weeks ago, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9, according to the US Geological Survey. This year is off to a fast start with 40 so far—more than in most years for that time period.
But that’s because the 8.8 quake in Chile generated a large number of strong aftershocks, and so many quakes early this year skews (扭曲) the picture, said Paul Earle, a US seismologist (地震学家).
Also, it’s not the number of quakes, but their devastating impacts(破坏性的影响) that gain attention, with the death tolls (死亡人数) largely due to construction standards (building standard) and crowding, Earle added. “The standard mantra (咒语) is earthquakes don’t kill people, buildings do, ” he said.
There have been more deaths over the past decades from earthquakes, said University of Colorado geologist Roger Bilham. In an opinion column last month in the journal Nature, Bilham called for better construction standards in the world’s big cities.
Of the 130 cities worldwide with populations of more than 1 million, more than half are prone (倾向于) to earthquakes, Bilham said.
Developing nations, where populations are growing, don’t pay attention to earthquake preparedness, Bilham said.” If you have a problem feeding yourself, you’re not really going to worry about earthquakes.”
Another reason quakes seem worse is that we’re paying attention more. The Haiti earthquake quickly followed by the 8.8 in Chile made everyone start to think.
But it won’t last, said US disaster researcher Deniis Mileti. “People are paying attention to the violent planet we’ve always lived on,” Mileti said.” Come back in another six months if there has been no earthquakes, most people will have forgotten it again. ”

To what degree can a computer achieve intelligence？The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child’s age returns. “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com.
Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. Artificial Intelligence, he must overcome two problems.
The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
From the text we can infer that www.intellicast.com is a website .

A．where we people can find Smarter Child

B．which is specially designed to help Smarter Child

C．where weather forecasts are made

D．which is about artificial intelligence

It is probably most difficult for Smarter Child to.

C．Smarter Child	D．The Future of Internet

People have wondered for a long time how their personalities and behaviors are formed．It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive．
Social scientists are, of course, extremely interested in these types of questions．They want to explain why we possess certain characteristics and exhibit certain behaviors．There are no clear answers yet, but two distinct schools of thought on the matter have developed．As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory．The controversy is often referred to as “nature and nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors．That our environment has little, if anything, to do with our abilities, characteristics, and behavior is central to this theory．Taken to an extreme, this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts（本能）．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act．A behaviorist, B．F．Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings．The behaviorists’ view of the human being is quite mechanistic; they maintain that, like machines, humans’ respond to environmental stimuli（刺激） as the basis of their behavior．
Socially and politically, the consequences of these two theories are far-reaching．In the US, for example, blacks often score below whites on standardized intelligence tests．This leads some “anature” proponents to conclude that blacks are genetically lower in status than whites．Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do．
Either of these theories cannot yet fully explain human behavior．In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes．That the controversy will continue for a long time is certain．
This passage is mainly concerned with．

A．relation between personality and behavior

B．relation between behavior and environment

C．different accounts of patterns of human behavior

D．different theories of the formation of human behavior

D．To present an argument in the field of social science．

A new power plant in Nakoso, Japan, might someday change everything for coal plants．Since the new power plant fired up in September, the designer, Mistubishi, is expecting to prove it's possible to burn coal without polluting．This technology is known as integrated gasification combined cycle （IGCC）．Proving IGCC works should give Mitsubishi's US partner, NRG Energy, the jump other hurdles to building new clean plants．
The project promised to solve the problem of the ages for power plants: how to produce cheap, clean, reliable electricity．No existing technology can do all three perfectly．
The problem is IGCC isn't there yet．It costs about 20 percent more than traditional plants．And even though it's easier to collect the resulting carbon dioxide from an IGCC plant than a traditional plant, there's no proven way to get rid of the greenhouse gas．One plan is to drill a shaft（通道） to pump the carbon dioxide underground, into saltwater formations．But there's no guarantee it will remain underground forever．
NRG administrators think solving the IGCC riddles is worth the trouble because they expect the U．S．will soon limit the amount of carbon dioxide that power generators may give out ．
"With the additional cost of IGCC, to just voluntarily build something that's 20 percent more expensive, that’s commercial suicide," NRG chief administrator, David Crane said．
NRG administrators expect the cost to decline after six or seven plants are built．But other industry experts think it will take about a dozen plants for the price to be competitive with traditional coal plants．
Takaya Watanabe, a vice general manager of Mitsubishi, admits that the cost challenges are difficult．“It’s good for a company to say we want to be green, but unless someone is willing to pay, it's a dream．It won't keep our family eating rice," he said．
What is expected of the new technology?

A．To make electricity without polluting the air．

B．To produce energy without burning coal．

C．To keep the use of electricity cheaper．

D．To pump carbon dioxide more easily ．

What's the biggest problem the companies are faced with?

A．How to pump greenhouse gases．

B．How to deal with the high cost．

C．How to get along with other partners．

D．How to improve the new technology．

What can be inferred from the passage?

A．New technologies are unacceptable to people．

B．It's unlikely to build more new power plants．

C．The companies are run on a tight budget．

D．Going green is easier said than done．
