     Yasuda is 95 years old. He and his colleagues, looking for easier ways to search the Web and send
e-mail, represent a potential market for Apple (AAPL)'s iPad. The company has sold 3.27 million iPads
since its launch in April, but doesn't break down sales figures by customer age, making it impossible to
know with certainty how many old people are buying them. However, evidence suggests it's popular
with the old.The iPad's intuitive interface (直观界面) makes it attractive to old citizens around the world,
says Takahiro Miura, a researcher at the University of Tokyo: "The iPad is a good tool for the elderly
because it's very forgiving of mistakes." Miura's team uses computers to help train senior citizens to rejoin
the workforce. "Unlike the PC, it doesn't require previous(先前的) knowledge," he says.
     James Cordwell, a technology analyst at Atlantic-Equities in London, says the iPad's popularity with
the elderly is helping Apple reach beyond its traditional base of younger customer. "The world's
population, especially in developed markets, is getting older, and it's probably a market where Apple has
least entered," Cordwell says. Elderly users are "a key source of growth for them in the future."
     The elderly in Japan, who make up an estimated 22 percent of the population, may prove particularly
quick to accept the iPad. They spend more than any other group in the country except for those under 30, according to a report by Japan's Cabinet Office. Motoo Kitamura, 78, a former gas salesman, bought an
iPad to help him communicate with his 2-year-old grandson and prevent against dementia(痴呆). "Trying
new things like that is a good mental exercise," he says.
1. Which of the following is TRUE according to the passage?
A. The iPad was only intended for elderly people.
B. The use of iPad requires previous knowledge.
C. The use of iPad is mentally useful to the old.
D. Only the elderly in Japan can use iPad.
2. What can we infer from Paragraph 1?
A. The old get a bit strike from the iPad.    
B. The iPad causes a heavy burden to the old.
C. The iPad is accepted by the old.          
D. The old are very familiar with the iPad.
3. Which of the following is NOT the advantage of the iPad over the PC?
A. It has intuitive interface.          
B. It is easier to operate.
C. It is more accessible to beginners.      
D. It is a good mental exercise.
4. What can we learn from the passage?
A. The old are the largest consumers in Japan.
B. The iPad is traditionally accepted by the young.
C. The old in Japan are fond of latest hi-tech products.
D. The old customers will soon replace the younger ones.
5. What could be the best title for the passage?
A. The iPad Leads Apple to the Elderly
B. Ipad Hits Japan's Store Shelves
C. Ipad's Arrival in Tokyo Causes Japanese to Excite
D. AAPL Tries to Balance the Old and the Yong

     When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that
eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are
interested in what the bears leave behind; their poop (排泄物). At a recent meeting in Denver, Professor Brown
at the university presented her research showing how panda poop could inspire a new way to obtain energy
from plants, which are a renewable energy source. Usually, plants can be called biomass (有机燃料) when
they are used as an energy source.
     Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists
something about breaking down biomass. Pandas - or at least the bacteria in their stomachs - are very good at
getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda
has only one stomach. Bamboo comes in, and poop goes out.
     Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two
pandas. Ya Ya and Le Le living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break
down biomass, including one that had never been found in pandas. Brown says that because the poop contains
bacteria that break down biomass, it could also be used to break down other types of biomass.
     Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and
then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn
biomass - like grass or other plants - into fuel.
     Brown says she doesn't mind handling panda poop."It's probably the most pleasant material to work with,"
she says,"My colleagues and I have been working with other poop for a long time, and we can assure you it
has a fairly pleasant smell associated with it."

A. to explore a new way to get energy from plants
