Asteroids are bigger versions of the meteoroids that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth. Buy $50 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one.the scientists say, we'll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall.it would be the end of the world. “If we don't take care of these big asteroids, they'll take care of us, says one scientist. “It's that simple. The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday rocks than from a great nuclear fleet set against them, said a New York Times article.

Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.
  One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.
Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack(群)by using extreme measure. You can teach your dog its subordinate(从属的)role by teaching it to show submission to you. Most dogs love performing tricks for you to
pleasantly accept that you are in charge.
  Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.
51. Behavior problems of dogs are believed to _______.
A. be just part of their nature
  B. worsen in modern society
