Recently scientists have worked out a way to judge roughly where a person has lived using strands(缕) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid（列阵）falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can establish a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a frame of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
“It’s not good for pinpointing (精确定位),” he said. “It’s good for ruling out many possibilities.”
64. What can we learn from the passage about the latest discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
65. What does the underlined word “identical” in paragraph 3 probably mean?
A. similar B. fantastic C. beneficial D. healthy
66. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.

LOS ANGELES-British singing sensation Susan Boyle’s first album quickly climbed to No. 1 on U.S. album charts on Wednesday with sales of 701,000 copies, beating new releases by Adam Lambert and Rihanna and becoming the best-selling debut(首次演出) of 2009. Boyle, 48, a frumpy Scottish singer, who became an international YouTube phenomenon after appearing on TV show “Britain’s Got Talent”, also topped the British album charts earlier this week.
Her “I Dreamed a Dream” release through Sony Music Entertainment, marked the best U.S. opening of a female artist's debut album since Nielsen SoundScan began tracking sales in 1991, Billboard.com said. It was also the fastest selling album in Britain this year and has topped the charts in Australia and Ireland.
Billboard said only one album in SoundScan’s tracking history had seen a bigger opening week than Boyle. U.S. rapper Snoop Dogg’s album “Doggystyle” sold 803,000 copies in its first week in 1993—before traditional album sales began tumbling(falling rapidly) in the face of piracy(盗版) and a shift to digital sales.
Although Boyle finally failed to win “Britain’s Got Talent”, her April trial hearing for the show has been viewed more than 300 million times on the Internet.
In a good week for stars of TV talent shows, “American Idol” runner-up Adam Lambert’s debut album “For Your Entertainment”, also released through Sony, debuted at No.3 on the Billboard 200 with 198,000 copies sold. Lambert’s strong showing followed headline news coverage of his bad televised live performance at the American Music Awards 10 days ago in which he aroused oral sex with a dancer and kissed a male keyboard player.
R&B singer Rihanna’s “Rated R”, her first studio album since being attacked by her then-boyfriend Chris Brown in February, bowed in at No.4 with 181,000 copies—the best sales week in the 21-year-old singer’s career.
Italian singer Andrea Bocelli held onto the No.2 spot for a third week with his “My Christmas” album with 218,000 new copies sold during the week, SoundScan said.
60. According to the passage, what albums were released through Sony Music Entertainment?
A. Doggystyle and I Dreamed a Dream.
B. For Your Entertainment and I Dreamed a Dream.
C. Rated R and Doggystyle.
D. My Christmas and For Your Entertainment.
61. What do you learn from the passage?
A. Doggystyle marked the biggest opening week in SoundScan’s tracking history.
B. I Dreamed a Dream was the fastest selling album in English-speaking countries.
C. Upon its release, Boyle’s first album ranked first on album charts on Wednesday.
D. Boyle became world-famous after she won Britain’s Got Talent.
62. Who may perform crazily and leave audience a bad impression?
A. Susan Boyle. B. Andrea Bocelli. C. Rihanna. D. Adam Lambert.
63. From the passage we can conclude _______.
A. The albums could have sold better if it had not been for piracy and a shift to digital sales
B. Boyle became world-famous because she was a female artist.
C. Being attacked by her then-boyfriend might decrease the sales of Rihanna’s Rated R.

The iPad, a new e-tablet gadget will take online activities truly mobile. It will allow you to read the news in bed, play multiplayer game on any surface, check a recipe in a busy kitchen or view a large-scale Google map.
It will declare a new age of online media production, taking newspapers and magazines down the new stage. Online versions can now become truly interactive. The editor of Time magazine Richard Stengel said, “The iPad will transform the way journalism works. It will become a new way of storytelling”.
Perhaps most important to the masses, it is a traditional computer but so convenient to use. There are no cords(电线), and it’s totally mobile. You press a button and it comes on in seconds. To add a program, you just download it from the Internet. There is no file directory, so you won’t be confused with file locations.
Since almost everyone uses a computer in the office or at school, the need for the traditional desktop model at home is disappearing. Slate Magazine’s Farhad Manjoo calls the iPad the perfect alternative to the full home computer system.
However, opinions are summarized as a simple statement: If you are a tech-head you will hate it, if you are everyone else you will love it. It’s “laughably absurd” on one blog and a “magical revolution” on another.
This first version of the iPad lacks many basic features. Tech-heads dislike the device not because of what it offers, but because of what it doesn’t offer. It doesn’t have flash or a camera. It can’t access many of the world’s mobile applications, and it has a very restricted APPLE store. Based on purely technological grounds, the iPad is said to lack more than it gives.
But if you are not part of the technologically well-versed, and you love the iPod and iPhone, “this device is for you,” said Steve Jobs, Apple’s CEO.
But no matter how you feel about the iPad, as a tech-head or an everyman, there’s no arguing with its appeal. Love it or hate it, the iPad sold over 600,000 units on its opening weekend, surpassing(超过) the iPhone’s record sales in 2007.
It’s uncertain how long it will take to hit the tech markets here in China, but when it does, expect the iPad fashion to continue. Apple predicts it will sell over 7.1 million units in the first year. Maybe not magical, and definitely not absurd, but if the iPad follows in the footsteps of the iPhone and iPod, you could be reading this newspaper on it in the near future.
56. Which of the following is NOT the reason why people think the iPad a “magical revolution”?
A. The iPad will make online activities truly mobile.
B. The iPad will predict a new age of online media production.
C. The iPad is sure to take the place of the full home computer system.
D. The iPad can make many world’s mobile applications accessible.
57. Which of the following statements is false according to the passage?
A. Unlike those traditional computers, the iPad can save you much trouble.
B. The iPad set up a new record sale when it first came onto the market.
C. The iPad will probably hold a big share in the tech market in China.
D. The iPad depends on cords to download a program from the Internet quickly.
58. What technological problem do experts think the iPad has?
A. The iPad is lacking in what other computers can offer.
B. People might misunderstand its magical features.
C. Reporters and journalists don’t have to efficiently with the help of the iPad.
D. Compared with the iPhone and iPod, iPad might confuse the users more easily
59. Which of the following would be the best title for the passage?
A. Why do People Love the iPadB. The Popularity of the iPad
C. Loving and Hating the iPad D. A Magical Revolution

Climate has been a major driver of armed conflict in Africa, research shows—and future warming is likely to increase the number of deaths from war. US researchers found that across the continent, conflict was about 50% more likely in unusually warm years.
Writing in Proceedings of the National Academy of Sciences (PNAS), they suggest conflict arises when the food supply is not enough in warm conditions. Climatic factors have been mentioned as a reason for several recent conflicts. One is the fighting in Darfur in Sudan that has killed 200,000 people and forced two million more from their homes. Previous research has shown an association between lack of rain and conflict, but this is thought to be the first clear evidence of a temperature link.
The researchers used databases of temperatures across sub-Saharan Africa for the period between 1981 and 2002, and looked for connections between above average warmth and civil conflict in the same country that left at least 1,000 people dead. "Studies show that crop output in the region is really sensitive to small shifts in temperature, even of half a degree or so," research leader Marshall Burke, from the University of California at Berkeley, told BBC News.
"Our findings provide strong motivation to increase investments in African adaptation to climate change by such steps as developing crop varieties less sensitive to extreme heat and promoting insurance plans to help protect farmers from negative effects of the hotter climate," said Dr Burke. "If the argument is that the trend towards rising temperatures will increase conflict, then we need to do something around climate change, but more fundamentally we need to resolve the conflicts in the first place."
If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be unimaginable. If temperatures rise across the continent as computer models project, future conflicts are likely to become more common, researchers suggest. Their study shows an increase of about 50% over the next 20 years.
When projections of social trends such as population increase and economic development were included in their model of a future Africa, temperature rise still emerged as a likely major cause of increasing armed conflict. At next month's UN climate summit (峰会) in Copenhagen, governments are due to debate how much money to put into helping African countries prepare for and adapt to negative effects of climate change.

Around half of all teenagers in the UK are putting themselves at risk of food poisoning because they don't wash their hands before eating or after visiting the toilet, a new survey indicates, To coincide with National Food Safety Week, researchers from the Food and Drink Federation (FDF) conducted a survey of over 500 people aged between 11 and 19 about their hygiene and eating habits. Their survey showed that 57 percent of teenagers admitted to not always washing their hands after visiting the toilet or before lunch at school. Of these, over two-thirds ate lunch, such as sandwiches or a burger, with their hands.
Furthermore, 40 percent of those who do wash their hands do not always use soap. And 75 percent said they dry their hands on their clothes when in a hurry—damp hands spread around 1,000 times more germs (病菌) than dry ones. Excuses that teenagers gave for not washing their hands ranged from not having enough time (24 percent) to dirty and unhygienic facilities (26 percent) and forgetfulness (22 percent).
Food safety expert Hugh Pennington, professor of Microbiology at Aberdeen University, said, "The best news about food safety is that one doesn't have to be a rocket scientist to do it properly. The had news is that even a simple and obvious thing like hand washing—which protects incredibly well—is seen by many people as good health theory, but not actually put into practice."
Martin Paterson, deputy director general of the FDF, said that teens' hygiene habits before eating were a recipe for disaster, adding that although most know how food poisoning could occur, the majority do not take simple measures to prevent it. "Of course teenagers don't want to be overprotected," he said, "but with up to 5.5 million cases of food poisoning a year, we clearly need to keep informing people of simple food hygiene messages in fun and imaginative ways, to remind people of all ages how they can continue to enjoy their food safely."
53．The author implies that it is important to dry hands because .
A．some students dry their hands on their clothes
B．wet hands can cause students to catch cold
C．damp hands are more likely to spread germs
D．damp hands take 1,000 times longer to dry
54．By saying "one doesn't have to be a rocket scientist to do it properly" (Para. 3), Hugh Pennington means "____".
A．it isn't necessary to go to outer space to practice food safety
B．practicing food safety isn't as important as space exploration
C．it's not a must to practice food safety
D．practicing food safety isn't terribly difficult
55．Educated about food poisoning, most teenagers .
A．still get food poisoning at least once a year
B．still fail to take simple measures to avoid it
C．are able to avoid food poisoning
D．are concerned about their food safety
56．What is the main message conveyed in the text?
