　　Galileo left earth on October 18, 1989．In 1995, it became the first man-made satellite of Jupiter(木星)．

　　Galileo released its 339 kg probe(an exploring machine)in July 1995 and it went into the atmosphere of Jupiter in December．Travelling at 47 km per second, Galileo’s cone-shaped(锥形的)probe became a man-made meteor(大气现象)burning across alien cloud．Within two minutes the drag caused by Jupiter’s atmosphere slowed the probe to a mere 1600 km per hour．

　　The following are some information about Galileo and Jupiter．

　　Galileo’s Mission：

　　Take pictures of Jupiter and its moons

　　Weigh planet and its moons

　　Check temperatures, chemical make-up, magnetic strength, protons(质子), heavy ions(离子), electromagnetic waves and dust particles．

　　Galileo Facts：

　　Weight：2380 kg

　　Dimensions：4.5 m high, 10.9 m long

　　Thermal nuclear power：570 watts

　Jupiter Facts：

　　Fifth planet from the sun(after Mercury, Venus, Earth, Mars), 700 million km from earth at the moment．

　　Largest planet in solar system：

　　Diameter：142 000 km(Earth：12 750 km)

　　Spins on axis(day length)：10 hours(Earth：24 hours)

　　Moons：16

　　Made of swirling(漩涡), hot gases, no rocky surface

　　Gaseous red spot：40 000 km across

答案：1．B;2．B;3．D;4．A;5．D;
解析：

(1)

Galileo是在空间执行任务的人造卫星。

(2)

下文提到了木星的一些数据，这些都是空间探测器带回来的。

(3)

Galileo共有三个使命，测出木星的重量便是其中之一(weigh Jupiter)。

(4)

木星一天有10个小时，地球一天有24个小时。

(5)

木星是由漩涡、热气等组成的(made of swirling，hot gases，no rockey surface)，这种环境不利于生命的活动，因此可以推断上面可能没有生命。

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　America is the land of the automobile. “This country has only 6 percent of the world's population out of 46 percent of the world's cars. Right now, there are 97 million privately owned cars consuming 75 billion gallons of gasoline and traveling an estimated 1,000 billion miles a year. The figures also affirm something we know every time we refill our gasoline tank. The automobile is a very thirty piece of technology. Of the total petroleum supply in the United States, 30 percent goes to quench that thirst. Every year for each passenger car, about 800 gal lons of gasoline are consumed.

　　Other aspects of our commitment to the automobile also bear mentioning here. It takes a great deal of energy to manufacture one automobile - about 150 million BTU's of energy. This is equivalent to 1,200 gallons of gasoline, enough to run a car for about 1,600 miles. We expend energy in the process of shipping cars from factories to showrooms, displaying them for sale and making replacement parts for repairs. One out of six jobs in the nation is associated with the automobile business. About two gallons of gasoline are consumed in the process of making every ten gallons that are pumped into an automobile's gas tank.

　　Building highways and parking lots has used up much of our land. It has been estimated that we have paved over 21,000 square miles of this country's surface, most of it to accommodate the automobile. The automobile is also the largest contributor to our nation's air pollution problem and a very serious one because most of its pollutants are emitted in our large metropolitan areas.

1．To make an automobile, we need ________.

[　　]

A．75 billion gallons of gasoline

B．150 million BTU's of energy

C．1,200 gallons of gasoline

D．800 gallons of petroleum

2．The underlined word “quench” in this passage means ________.

[　　]

A．stop
B．satisfy
C．reduce
D．cool

3．The main idea of this passage is ________.

[　　]

A．what the automobile costs and brings

B．how to make the automobile

C．the energy the automobile costs

D．the problem the automobile has brought

　　The government-run command post in Tunis is staffed around the clock by military personnel, meteorologists and civilians．On the wall are maps, crisscrossed with brightly colors arrows that painstakingly track the fearsome path of the enemy．

　　What kind of invader gives rise to such high-level monitoring? Not man, not beast, but the lowly desert locust(蝗虫)．In recent months, billions of the 3-inch-long winged warriors have descended on Algeria, Libya, Morocco and Tunisia, blackening the sky and eating up crops and vegetation．The insect invasion, the worst in 30 years, is already creating great destruction in the Middle East and is now treating southern Europe．The current crisis began in late 1985 near the Red Sea．Unusually rainy weather moistened the sands of the Sudan, making them ideal seedbed for the locust, which lays its eggs in the earth．The insect onslaught threatens to create yet another African famine．Each locust can eat its weight(not quite a tenth of an ounce)in vegetation every 24 hours．A good-size swarm of 50 billion insects eats up 100,000 tons of grass, trees and crops in a single night．

　　All ﹩150 million may be needed this year．The U．S．has provided two spraying planes and about 50,000 gal．of pesticide．The European Community has donated ﹩3．8 million in aid and the Soviet Union, Canada, Japan and China have provided chemical-spraying aircraft to help wipe out the pests．But relief efforts are hampered by the relative mildness of approved pesticides, which quickly lose their deadly punch and require frequent replications．The most effective locust killer dieldrin has been linked to cancer and is banned by many Western countries and some of the affected African nations．More than 5 million acres have been dusted with locust-killing chemicals; another 5 million will be treated by the end of June．

　　On May 30, representatives of Tunisia, Algeria, Libya, Morocco and Mauritania will meet in Algiers to discuss tactics to wipe out the ravenous swarms．The move is an important step, but whatever plan is devised, the locust plague promised to get worse before the insects can be brought under control．
