When a dog bites a man, it usually doesn’t make news. However, this saying change when Beijing and several other Chinese cities announced the “Civilized Dog Raising” campaign in November.
The government will require Beijingers to get licenses for their dogs, and will enforce the one-dog, one-family policy. Police say the "one-dog policy" is aimed at reducing the number of dog bites and lowering the risk of rabies. According to the Ministry of Health, rabies has become the top infectious disease in China. Dangerous dogs and dogs taller than 35 centimeters, such as Great Danes, have been banned from urban areas.
Pet owners are also required to clean up their dog's droppings and make sure dogs are leashed (拴着), especially in public areas. Some public areas, such as banks, are closed to dogs entirely.
Dogs are regarded as man's best friend and the history of raising dogs can be traced back to the stone age. It therefore seems sad that dogs are unwelcome in Beijing. But it is not the case that Beijingers dislike dogs. Actually, there are many dog lovers in Beijing. The city now has more than 550,000 registered dogs, up 20 percent from the previous year.
The problem is, actually, about living space. Different from many Westerners, most Beijingers live in urban apartment buildings, not houses in the suburbs. There is very limited open space for walking dogs. The barking, the waste, and unleashed dogs in buildings, elevators and places people gather can cause fear, fights and frustration.
Beijing is not the only city to have a dog problem. Paris, London, New York and Vienna all face similar challenges and have common rules for dogs and their owners.

Move Earth – it’s no science fiction
LONDON – Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets (彗星) in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA）engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）— by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.
1.What makes the scientists plan to move Earth?
A．A few comets are moving to the direction of Earth.
B．Earth’s working life is coming to an end soon.
C．Earth will become too hot for mankind to keep alive.
D．The moon is moving farther and farther away from Earth.
2.If the plan is successful, Earth will have a working life of ______years.
A．12 billion B．6 billion C．18 billion D．24 billion
3.What serious problems might the plan cause according to the passage?
A．The comet might hit Earth and man might lose the moon.
B．Earth might be moved too far away and man might be frozen to death.
C．The comet might hit Jupiter or Saturn and never return to Earth.
D．Earth’s working life might be greatly shortened.
4.What does the underlined word “compromise” mean?
A．provide B．benefit C．share D．endanger
