Digital television broadcasting, the “TV of the 21st Century”, was launched in Japan on Dec．1, 1999．

　　At first, the service is limited only in three of Japan's largest cities Tokyo, Osaka and Nagoya, but the Japanese government is aimed to make it available in all major Japanese cities by the end of 2006．The government says that by July 24, 2011, analog (模擬) television broadcasting in Japan will officially be a thing of the past．

“As we mark 50 years since the start of analog television broadcasting in 1953, I believe we are at a historic moment as television evolves one step further,” said Japanese Prime Minister Junichiro Koizumi．

　　For now, it's estimated that about 12 million families around the area of the three above-mentioned cities can enjoy the service of digital television broadcasting．But because of Japan's mountainous terrain (地形), actual viewers may be as low as 300,000, according to scientists．

　　To watch digital television broadcasting, viewers need to get a digital TV set or attach a tuner (調(diào)諧器) to an ordinary one．

　　Scientists say the service of digital television broadcasting may not become popular in Japan for a while because most Japanese are not familiar with it now．A recent survey found 40 percent of Japanese TV viewers know nothing about the digital broadcasting technology．

1．What may limit the number of the viewers of digital television broadcasting?

[　　]

A．The TV viewers lack the digital television broadcasting technology．

B．Most Japanese are living in mountains．

C．The majority of Japanese are unwilling to fit a tuner to an ordinary TV set．

　　Watching 3D films such as Avatar could give some viewers headaches, experts have warned．

　　The success of James Cameron's science-fiction blockbuster(賣座的大片), which has already taken more than ＄1 billion(￡600 million)at the box office, is fuelling a surge in popularity for three-dimensional movies and new 3D television sets．

　　But prolonged viewing may result in an aching head, according to Dr Michael Rosenberg, an ophthalmology(眼科學)professor at Northwestern University Feinberg School of Medicine in Chicago．

　　He said："There are a lot of people walking around with very minor eye problems, for example a minor muscle imbalance, which under normal circumstances the brain deals with naturally．"

　　Watching a 3D movie confronts viewers with an entirely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," he said．

　　Dr Deborah Friedman, a professor of ophthalmology and neurology(神經(jīng)學)at the University of Rochester Medical Center in New York, said："If your eyes are a little off to begin with then it's really throwing a whole degree of effort that your brain now needs to exert．This disparity for some people will give them a headache．"

　　Experts say there are no studies tracking how common it is to get a headache after watching a 3D film．

　　Rick Heineman, a spokesman for RealD, which provides 3D equipment to cinemas, said headaches and nausea were the main reasons 3D technology never took off before．

　　But he said new digital technology addresses many of the problems that had previously caused sore heads．

(1)

What can we learn from what Dr Michael Rosenberg said?

C．

D．

People come into very minor eye problems and a minor muscle imbalance when watching 3D films．

(2)

What does the underlined word “prolonged” in the 3rd paragraph mean?

[　　]

A．

constant

D．

Rick Heineman said that 3D technology would never take off headaches and nausea in future．
