In the United States in the early 1800’s, individual state governments had more effect on the economy than did the federal government. States controlled manufacturing, banking, mining and transportation firms and participated in the construction of various internal improvements such as canals, turnpikes（收费关卡）, and railroads. The states encouraged internal improvements in two distinct ways: first, by actually establishing state companies to build such improvements; second, by providing part of the capital for mixed public-private companies setting out to make a profit.
　　In the early nineteenth century, state governments also engaged in a surprisingly large amount of direct restricting activity, including extensive licensing and inspection programs. Licensing targets reflected both similarities in and difference between the economy of the nineteenth century and that of today: in the nineteenth century, state regulation through licensing fell especially on drug dealers, innkeepers and retail merchants of various kinds. The goods of trade generally came under state inspection and such important raw material as lumber and gunpowder were also subject to state control. Finally, state governments experimented with direct labor and business regulation designed to help the individual laborer or consumer, including setting maximum limits on hours of work and restrictions on price-fixing by business.
　　Although the states dominated economic activity during this period, the federal government was not inactive. Its goals were the facilitation of western settlement and the development of native industries. Toward these ends the federal government pursued several courses of action. It established a national bank to stabilize banking activities in the country and, in part, to provide a supply of relatively easy money to the region, where it was greatly needed for settlement. It permitted access to public western lands on increasing easy term, with a summit in the Homestead Act of 1862, by which title to land could be claimed on the basis of residence alone. Finally, it set up a system of tariffs（关税） that was basically protectionist in effect, although maneuvering for position by various regional interests produced frequent changes in tariff rates throughout the nineteenth century.

With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save these in a dangerous situation. That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark".
Noah's Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of these animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary, Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds and reptiles will probably become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
"The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it's difficult, but this could be                                                                                                                                                                                                      groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
"They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. The cooperation between us is very much needed."

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.
Long ago the Panamint Indians called this place "Tomesha"-- the land of fire. Death Valley's present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.
Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and colorful parts of Death Valley is the Devil's Golf Course, where it seems hard for one to tell reality from dreams. Sand sculptures stand on a frightening ground, as evening shadows move and lengthen.

Taiwan police cannot decide whether to treat it as an extremely clever act of stealing or an even cleverer cheat. Either way, it could be the perfect crime, because the criminals are birds—horning pigeons!
The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.
There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however, may in fact be the work of an even lazier and more inventive criminal mind—one that avoid not only collecting money but going out to steal the car in the first place . Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an ad in the newspaper asking for help.
The theory is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded-under 3,000 Taiwanese dollars –seems too little for a car worth many times more.
Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. “We have more important things to do,” he said.
1. After the car owner received a phone call. He ______.
A. went to a certain pigeon and put some money in the bag it carried
B. gave the money to the thief and had his car back in a park
C. sent some money to the thief by mail            
D. told the press about it

4. The underlined word “they” in the last paragraph refers to ______.
A. criminals                          B. pigeons                 
C. the stolen cars                           D. demands for money
5. We may infer from the text that the criminal knows how to reach the car owners because______.

Was Princess Diana murdered? The verdict（判决）is no according to an inquiry（调查）held into the cause of her death over the last six months.
The big question was whether the deaths of Diana and her boyfriend Dodi A1 Fayed in a deadly car crash in 1997 had been accidental, or whether there was some kind of conspiracy（阴谋）to have them killed.
Dodi’s father Mohamed A1 Fayed, owner of London’s world-famous department store Harrods, has insisted for the last decade that the pair were murdered by spies of the British state who did not want them to marry. But his theories now look to have been blown out of the water.  The court found that Princess Diana and her boyfriend were not murdered but killed due to the “gross, carelessness” of her driver and the paparazzi（偷拍的摄影记者）. Her driver was drunk at the time of the crash and the paparazzi had been running after their car.
So is this the end of the Diana story? British taxpayers may hope so. The inquiry has cost them about ￡10m（140m RMB）. “Thank God it’s over”, was the headline in The Guardian newspaper. UK Prime Minister Gordon Brown said it was time to “draw a line” under the death of the Princess. But Mohamed AI Fayed has refused to accept the judgment. He says the result will come as a “blow” to millions of his supporters around the world, and has not ruled out starting another investigation.
Whatever happens, next, the special place Princess Diana has in the hearts of people around the world is not likely to be forgotten.
1. According to the text, the inquiry focuses on _______.
A. what caused the deaths of Diana and her boyfriend   B. who were the paparazzi
C. how much British taxpayers paid for the case       D. whether the driver was drunk then.
2. By saying the underlined “his theories now look to have been blown out of the water”, the author means that ________.
A. Mohamed lacks confidence in the case   B. Mohamed feels disappointed at the result
C. Mohamed’s idea seems to be believable  D. Mohamed’s idea possibly proves to be wrong
3. Similar to The Guardian newspaper, UK Prime Minister ________.
A. felt sorry for the deadly car crash       B. questioned the purpose of Dodi’s father
C. stood for the court’s judgment         D. blamed the paparazzi for their bad behavior

Tamiflu does not kill but prevents H1N1 from further proliferation (繁衍) till the virus limits itself in about 1-2 weeks (its natural cycle)．H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there．The only way of entry are the nostrils(鼻孔) and mouth/ throat．In a global epidemic of this nature, it's almost impossible not coming into contact with H1N1．
Contact with H1N1 is not so much of a problem as proliferation is．
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1．Frequent hand-washing．
2．"Hands-off-the-face" approach．Resist all temptations to touch any part of face (unless you want to eat or bathe)．
3．Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt)．H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms．Simple gargling prevents proliferation．In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．Don't underestimate this simple, inexpensive and powerful preventative method．
4．Similar to 3 above, clean your nostrilsat least once every day with warm salt water，Which is very effective in bringing down viral population．
5．Strengthen your natural immunity with foods that are rich in Vitamin C ．If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption．
6．Drink as much of warm liquids as you can．Drinking warm liquids has the same effect as gargling, but in the reverse direction．They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm．
7．All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals．
1．What part of a person’s body do H1N1flu viruses mainly infect?
A．one’s lung            B．the upper respiratory tract
C．one’s heart            D．one’s throat and lung
2．H1N1 flu viruses go into our bodies by ________．
A．touching          B．diet      C．breathing  D．dirt
3．What does the underlined word “underestimate” mean ?
A．assign too low a value to
B．drop the cost of
C．pay more attention to
D．calculate the number of money
4．The author presents this passage by ______．
A．telling an interesting story         B．testing an idea by reasoning
C．introducing some practical methods    D．describing some activities in a natural order

Supermarkets are trying out new computers that make shopping carts more intelligent(具备智能的). They will help shoppers find paper cups or toilet soap, and keep a record of the bill.
The touch-screen devices(触摸屏装置) are on show at the Food Marketing Institute’s exhibition here this week, “These devices are able to create value and get you around the store quicker,” said Michael Alexander, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.
Canadian stores will test the Concierge in July. A similar device, IBM’s “Shopping Buddy”, has recently been test-marketed at Stop & Shop stores in Massachusetts.
Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.
“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexander. “They’re not watching 30-second TV ads anymore.”
People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system(系统) that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.
The device also keeps a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.
The new computerized shopping assistants don’t come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.
1. The underlined word “they” (paragraph 1) refers to ______.
A. supermarkets  B. shop assistants    C. shopping carts           D. shop managers
2. Which of the following is the correct order of shopping with computerized shopping carts?
a. Start the system.                                               b. Make a shopping list.
c. Find the things you want.                                  d. Go to a self-checkout stand.
A. abdc                            B. bacd                        C. acbd                        D. bcad
3. We can learn from the last paragraph that ______.
A. intelligent shopping carts cost a large sum of money
B. the Concierge is cheaper than the Buddy devices
C. shop assistants with computer knowledge are well paid
D. average stores prefer the Concierge to the Buddy devices
4. What might be the most suitable title for the text?
A. New age for supermarkets                 
B. Concierge and Shopping Buddy
C. New computers make shopping carts smarter            
D. Touch-screen devices make shopping enjoyable

Special Bridges Help Animals Cross the Road
——Reported by Sheila Carrick
Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Ecopassages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These ecopassages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lions used the passage.
Builders of ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animals overpass!
1. The writer uses the example of “ocelots” to show that ______.
A. wild animals have become more dangerous
B. the driving conditions have improved greatly
C. the measure for protecting wildlife fails to work
D. an increasing number of animals are killed in road accidents
2. From the news story, we know an ecopassage is ______.
A. an underground path for cars                                  
B. a fence built for the safety of the area
C. a bridge for animals to get over a river                    
D. a pass for animals to cross the road
3. When the writer says that animals seem “to be catching on”, he means ______.
A. animals begin to realize the dangers on the road 
B. animals begin to learn to use ecopassages
C. animals are crossing the road in groups                    
D. animals are increasing in number
4. The writer asks visitors and drivers to look around when traveling because ______.
A. wild animals may attack cars                                  
B. wild animals may jam the road
C. they may see wild animals in the park               
D. they may see wild animals on ecopassages

The British royal family is about to be slimmed down. The Queen plans to reduce the number of real royals, it was recently announced. However, there seems little sign of the monarchy (君主) disappearing completely.
Up till the 17th century, the British king or queen was believed to rule by “divine (神的) right”, which was the idea that God chose the king or queen to rule and that he or she was therefore above the law. However, this idea ended with the English Revolution, in which King Charles I was imprisoned and then beheaded (斩首) in 1649.
So what role does the British royal family have today?
Well, the Queen has important formal duties as Head of State, the Queen represents the UK on visits abroad and invites other world leaders to visit the UK. As Head of the Armed Forces: Only the Queen can declare when the UK is at war or when war is over. The Queen also has constitutional duties: She has to sign many government and Commonwealth (英联邦) documents everyday.
In addition, the royal family sends a great deal of its time traveling up and down the country in support of different charity projects.
But republicans in Britain do not believe there should be a royal family. Sometimes, the press and media criticize the royal family as well. One criticism is that British people should have to pay for the royal family through their taxes.
Today, the royal family works hard to be relevant(相关联的) in the modern world. The Queen Speech on television is less formal every Christmas, and is now available as a podcast (播客). In 2005, after graduating from university, Prince William spent time teaching English in Uruguay, the sort of work many young British people do at some time in their lives.
1.    What can be concluded from the first two paragraphs?
A. The British King or Queen is now considered above the law.
B. The British King or Queen is no longer believed to rule by divine right.
C. The royal family played a less important role in Britain in the late 17th century than in nowadays.
D. The English Revolution put an end to the British royal family in 1649.
2.    Which of the following is NOT among formal duties of the Queen?
A. Traveling around the UK.
B. Declaring when the UK is at war.
C. Inviting other leaders to visit the UK.
D. Signing Commonwealth documents every day.
3.    With the example of Prince William in the last paragraph, the author intends to show _____.
A. Prince William is very popular in the UK
B. the royal family is trying to connect better with ordinary people
C. Prince William has made an effort to win young people’s admiration
D. many young British people do voluntary work
4.    According to the article, British people __________.
A. are all in favor of the royal family
B. can talk to the Queen through a podcast
C. pay for the royal family through the taxes
D. criticize the royal family through media and press
