The use of the mobile Internet in Britain grew eight times as fast as the growth of the PC Internet, according to the latest study from research firm Nielsen Online. Of course, the actual number of Britons surfing the PC Internet is much higher. A recent report found that from April to September in 2008, the number of Britons using the mobile Internet increased by 25 percent, from 5.8 million to 7.3 million. However, the number of Britons surfing the PC Internet is 35.5 million, up only 3 percent. As expected, the report found that the mobile online audiences are younger than the PC-based users, with 25 percent of mobile Internet users aged 15-24 years old, compared to 16 percent for PC-based users. Also as expected, there are more people aged over 55 surfing the PC Internet (23 percent) than those on the mobile Internet (12 percent). This last figure —12 percent of those aged over 55 surfing the mobile Internet, however, surprised me because I had expected to be lower. Mobile audiences are interested in sites that can provide immediate information, or immediate access like BBC News, Google Search, Sky Sports, BBC Weather and G-mail. BBC News is visited by nearly one in four British mobile Internet users, or 1.7 million people. Three of the most popular sites, BBC Weather, Sky Sports and G-mail, actually have a greater reach on the mobile Internet than they do on the PC Internet. BBC Weather gets 21 percent of all mobile users with 17 percent on the PC-based Internet.

阅读快车系列答案Scientists are worried that an asteroid(小行星) will possibly hit the earth in 2036. If scientists are right, planet earth is 24 years away from a major disaster.
Scientists have been monitoring the progress of a 390-metre-wide asteroid ever since it was discovered last June. They have announced that it could hit the earth, causing huge damage, in 2036.
NASA estimates that the impact from the asteroid named after Apophis and ancient Egyptian demon(魔鬼) would release more than 100,000 times the energy released in the nuclear explosion over Hiroshima. Thousands of square kilometers would be directly affected by the explosion. The whole planet would see the effects of the dust released into the atmosphere.
This is the worst possible scenario(情景) of any asteroid in recorded history.
Having more than 20 years’ warning of possible impact might seem plenty of time. But scientists insist that there is actually very little time left to decide.
Luckily, however, they aren’t short on ideas for deflecting the asteroid. The favored method is also probably the easiest—throwing a spacecraft at the asteroid to change its direction. The European Space Agency plans to test this in the next decade.
One idea that seems to have no support from astronomers is the use of explosive, although this sounds more likely to the public or Hollywood producer.
At present, scientists are trying to make a better estimate of how much time we have, through more observations.
In spring of next year, there will be another chance for radar observation of Apophis. This will help astronomers calculate the orbits of the asteroid more accurately.
If, at that stage, they can’t rule out an impact with the earth in 2036, the next chance to make better observations will not be until 2016, then 2029.
“If we wait until 2029 and the worst—case scenario turns out to be true, it would seem unlikely that we’d be able to do anything about 2036,” warns Prof Fitzsimmons.
1.What does the underlined word “deflecting” most probably mean?
|
A．making it smaller. |
|
B．observing it clearly enough. |
|
C．dividing into pieces. |
|
D．changing its direction. |
2.According to the scientists’ observation, _______.
|
A．the asteroid named Apophis will explode in 2036. |
|
B．the asteroid named Apophis might hit the earth in 2036. |
|
C．the asteroid named Apophis is 24 years old. |
|
D．there is plenty of time to decide the way we deal with the asteroid. |
3.What is the impact from Apophis if it hits the earth?
|
A．It will damage Hiroshima. |
|
B．Thousands of square kilometers would see the effects of the dust released into the atmosphere. |
|
C．It might be the worst damage caused by asteroids in recorded history. |
|
D．The whole planet would be directly affected by the explosion. |
4.It can be inferred from the text that _____.
|
A．Hollywood producers will explode Apophis to avoid its hit. |
|
B．There are only two chances for scientists to make better observations if they can’t grasp the chance next year. |
|
C．NASA plans to throw a spacecraft at Apophis to change its direction. |
|
D．It is supportive from astronauts that we explode the Apophis. |
