The world’s astronomers came to their senses yesterday and approved a new definition of the word “planet” that would drop tiny Pluto from the club and relegate it instead to a lesser realm of “dwarf planets.” It was a welcome step away from a proposal that would have kept Pluto as a planet but meantime opened the door for dozens of small, icy bodies on the fringes of the solar system.

The important vote came after fierce debate at a meeting of the International Astronomical Union, which had been considering a proposal to define a planet as any object that orbits a star and is large enough for its own gravity to pull it into a spherical (球形的) shape. That definition was scientifically precise but led to results that offended common sense. An asteroid, a small moon, and another icy ball like Pluto would suddenly have risen to planet-hood, swelling the number of planets to 12, with many more icy rocks likely to qualify as more was learned about them.

Fortunately, the astronomers have now added another requirement to the definition. Planets must not only be large enough to be round, they must also have cleared out the neighborhood around their orbits. Pluto would not qualify — it orbits in a belt of icy debris on the edge of the solar system. Neither would an icy rock nicknamed Xena, which orbits in that same zone, nor Ceres, a big asteroid that marches in the company of other asteroids. Pluto’s moon, Charon, which had qualified under the first proposal, is also out of the running.

Pluto, with its small size and oddball orbit, should never have been deemed a planet in the first place. Henceforth there will be eight planets, at least three dwarf planets, and tens of thousands of “smaller solar system bodies,” like comets and asteroids. Our only regret is that the astronomers chose the name “dwarf planets” for Pluto’s new category instead of abandoning the word entirely when discussing these less-than-planetary bodies.

46. We can know from the passage that the new definition of planet __________.

A. has been welcomed by all walks of life

B. will kick the Pluto out of the planet group in the solar system

C. still makes the Pluto as a planet

D. will enlarge the number of planets in our solar system into permanently 12

47. After the new definition of “planet” was put forward, all of the following are regarded as planet except________.

A. Venus               B. Ceres                       C. Mars                 D. Jupiter

48. The writer’s attitudes towards the new definition of “planet” is________.

   A. welcome             B. indifferent         C. hostile               D. neutral

49 If the original definition of “planet” had not been changed, there would be the following consequences except that ________.

   A. thousands of icy rocks in space will be classified as planets

   B. some asteroids big enough to pull itself into a spherical shape will be regarded as planets.

   C. the Pluto will be relegated to “dwarf planet”

   D. there will be at least twelve or even more planets in the solar system.

50. We can infer from the article that the decision to apply new definition to “planet”________.

   A. has won universal support from scientists.

   B. has been severely criticized by many astronomers

   C. has not been made inconsiderately.

   D. has been banned by the International Astronomical Union

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

For many years, scientists have warned that smoking tobacco is bad for health. Yet people around the world continue to smoke. The World Health Organization estimates that more than four million people die each year from the effects of smoking. That number is increasing.

Scientists have identified more than forty chemicals in tobacco smoke that cause cancer in humans and animals. Nicotine (尼古丁) is the major poison in cigarettes that gives pleasure to smokers. The American Cancer Society says nicotine can kill a person when taken in large amounts. It does this by stopping the muscles used for breathing. Also, studies have found that nicotine can be as harmful as alcohol or the illegal drugs. So experts say it is better never to start smoking and become dependent on nicotine than it is to smoke with the idea of stopping later.

Smoking tobacco is the leading cause of lung disease. Smoking also has been linked to heart disease, stroke and many kinds of cancer. American government health experts say smoking affects not only the smoker. Tobacco smoke also affects the health of people who do not smoke. Smokers may harm the health of family members and people at work. Tobacco smoke causes an estimated 3,000 non-smoking Americans to die of lung cancer each year.

Therefore, it can be seen that smoking begins to cause damage immediately. All cigarettes can damage the body. And there is no safe way to smoke.
