It is so hot and active that even the Suns

6、gravity cannot hold its atmosphere in check! Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma, and the stream of plasma coming from the Sun is called the solar wind. The more ac

7、tive the Sun, the stronger the solar wind.The solar wind constantly streams toward the Earth, but dont worry because a protective magnetic field surrounds our planet. The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles. The

8、charged particles become trapped in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earth s magnetic field, the magnetic field first gets squeezed and then the magnetic field lines break and reconnect.The breaking and reconnecting of the magnetic field lines can ca

9、use atomic particles called electrons trapped in the belts to fall into the Earth s atmosphere at the poles. As the electrons fall to the Earth, they collide with gas molecules in the atmosphere, creating flashes of light in the sky. Each atmospheric gas glows a different color. Oxygen and nitrogen

10、glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky, they create the Northern Lights and the Southern Lights.Watching auroras is fun and exciting, but normally you can only see them in places far north like Alaska and Canada. The movement of

11、the aurora across the sky is usually slow enough to easily follow with your eyes but they can also pulsate, flicker, or even move like waves. During solar maximum, auroras are seen as far south as Florida, even Mexico!Auroras often seem to be very close to the ground, but the lowest aurora is still

12、about 100 kilometers above the ground, a distance much higher than clouds are formed or airplanes can fly. A typical aurora band can be thousands of kilometers long, a few hundred kilometers high, but only a few hundred meters thick.We hope you are able to travel to far-north places like the Arctic

13、Circle and see the Northern Lights at least once during your lifetime. We know you will never forget it!16. The Suns gravity is too weak to keep its plasma from flowing to the Earth.A. Right B. Wrong C. Not mentioned17. The Earth is quite safe with a magnetic field surrounding it to protect it from

14、the attack by the solar wind.18. Some scientists are worrying about the possible disappearance of the Earths protective magnetic field in the future.19. The auroras are formed when the electrons falling into the Earth s atmosphere at the poles and colliding with gas molecules in the atmosphere.20. Y

15、ou cannot sec the Northern Lights unless you are in Alaska or Canada.21. Tens of thousands of tourists take special trips to Norway and Sweden every year to watch the Northern Lights.22. An aurora is generally close to the ground and is very long and thick.16-22 BACAB CB第 3 部分：概括大意与完成句子。下面的短文后有 2 项测

Maglev is short for magnetic levitation1, which means that these trains float over a guide way using

17、the basic principles of magnets to replace the old steel wheel and track trains.If youve ever played with magnets, you know that opposite poles attract and like poles repel each other. This is the basic principle behind electromagnetic propulsion. Electromagnets are similar to other magnets in that

18、they attract metal objects, but the magnetic pull is temporary. You can easily create a small electromagnet yourself by connecting the ends of a copper wire to the positive and negative ends of an AA-cell battery. This creates a small magnetic field. If you disconnect either end of the wire from the

19、 battery, the magnetic field is taken away.The magnetic field created in this wire-and-battery experiment is the simple idea behind a maglev train rail system. There are three components to this system： A large electrical power source, metal coils lining a guide way or track, and large guidance magn

20、ets attached to the underside of the train.The big difference between a maglev train and a conventional train is that maglev trains do not have an engine-at least not the kind of engine used to pull typical train cars along steel tracks4. The engine for maglev trains is rather innoticeable. Instead

21、of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combines to propel the trains.The magnetized coil running along the track, called a guideway, repels the large magnets on the trains undercarriage, allowing the train to levitate between 1

22、to 10 cm above the guideway. Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the train along the guideway. The electric current supplied to the coils in the guideway walls is constantly alternating

23、to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.Maglev trains float on a cushion of air, eliminating friction. This lack of friction

24、 allows these trains to reach unprecedented ground transportation speeds of more than 500 kph, or twice as fast as the fastest conventional train. At 500 kph, you could travel from Paris to Rome in just over two hours.23. Paragraph 3 _24. Paragraph 4 _25. Paragraph 5 _26. Paragraph 6 _A. The Main Co

28、 The telescope is called WISE and is about as wide around as a trashcan. Dont let its small size fool you： WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects in the known universe,including asteroids, faint stars, blazing galaxies and giant clouds of dust

29、where planets and stars are born.“Im very excited because were going to be seeing parts of the universe that we havent seen before,” said Ned Wright, a scientist who directs the WISE project.Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit （this means it crosses close to the north and south poles with each lap）. Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the
