Scientists are worried that an asteroid(小行星) will possibly hit the earth in 2036. If scientists are right, planet earth is 24 years away from a major disaster.
Scientists have been monitoring the progress of a 390-metre-wide asteroid ever since it was discovered last June. They have announced that it could hit the earth, causing huge damage, in 2036.
NASA estimates that the impact from the asteroid named after Apophis and ancient Egyptian demon(魔鬼) would release more than 100,000 times the energy released in the nuclear explosion over Hiroshima. Thousands of square kilometers would be directly affected by the explosion. The whole planet would see the effects of the dust released into the atmosphere.
This is the worst possible scenario(情景) of any asteroid in recorded history.
Having more than 20 years’ warning of possible impact might seem plenty of time. But scientists insist that there is actually very little time left to decide.
Luckily, however, they aren’t short on ideas for deflecting the asteroid. The favored method is also probably the easiest—throwing a spacecraft at the asteroid to change its direction. The European Space Agency plans to test this in the next decade.
One idea that seems to have no support from astronomers is the use of explosive, although this sounds more likely to the public or Hollywood producer.
At present, scientists are trying to make a better estimate of how much time we have, through more observations.
In spring of next year, there will be another chance for radar observation of Apophis. This will help astronomers calculate the orbits of the asteroid more accurately.
If, at that stage, they can’t rule out an impact with the earth in 2036, the next chance to make better observations will not be until 2016, then 2029.
“If we wait until 2029 and the worst—case scenario turns out to be true, it would seem unlikely that we’d be able to do anything about 2036,” warns Prof Fitzsimmons.
【小題1】What does the underlined word “deflecting” most probably mean?
A.making it smaller. |
B.observing it clearly enough. |
C.dividing into pieces. |
D.changing its direction. |
A.the asteroid named Apophis will explode in 2036. |
B.the asteroid named Apophis might hit the earth in 2036. |
C.the asteroid named Apophis is 24 years old. |
D.there is plenty of time to decide the way we deal with the asteroid. |
A.It will damage Hiroshima. |
B.Thousands of square kilometers would see the effects of the dust released into the atmosphere. |
C.It might be the worst damage caused by asteroids in recorded history. |
D.The whole planet would be directly affected by the explosion. |
A.Hollywood producers will explode Apophis to avoid its hit. |
B.There are only two chances for scientists to make better observations if they can’t grasp the chance next year. |
C.NASA plans to throw a spacecraft at Apophis to change its direction. |
D.It is supportive from astronauts that we explode the Apophis. |

Our lives were supposed to be more flexible and family-friendly thanks to the technology at our fingertips. But in this age of BlackBerrys, recession pressures, working at home after hours and on weekends, family time may not be working out the way we thought.
Busy parents who expected more time with the kids are Finding that more work hours at home don't necessarily translate into quality time with them.
A new generation of parents needs to discover the meaning of "quality time," researchers say. “Personally, just given the life I lead, I think there is something to this idea of quality time- spending productive time with children vs. just being around,” says Peter Brandon, a professor at Carleton College. He says engaging or interacting with a child in activities such as reading or playing counts as quality time rather than "passive monitoring," such as washing the dishes while the child is watching TV.
“This time with children pays off,” Brandon says. He notes that good parent-child relationships result in children being happier and more successful, including at school.
As parents struggle to be more available to their kids, new research on work and family schedules to be presented Friday at the meeting in Dallas includes a study that shows parents' availability is on the decline because more parents are in the workforce. Although parents today may be spending more time on child care, they are less available overall.
Working parents who spend less time with their children should try to make sure the time they do spend is communicating with them, vs. doing the dishes or spending more time on themselves, Brandon says “The trade-off is not necessarily taking away time from your kid,” he says "You're taking away time from other things”
【小題1】The first paragraph mainly intends to tell us that .
A.technology lets parents work at home |
B.parents are satisfied with their work |
C.technology makes our lives much easier |
D.the family time is not always satisfying |
A.some families are not experiencing quality time |
B.it's enough for parents to stay with their children |
C.parents enjoy engaging in work-at-home activities |
D.working hours at home can transform into quality time |
A.just, being around with children |
B.work time is separate from family time |
C.spending instructive time with children |
D.letting the children do whatever they want to do |
A.the time with children is of little value |
B.the time with children costs quite a lot |
C.the time with children leads to good result |
D.the time with children has a bad effect on them |
A.How to spend more time at home |
B.How to do the dishes in a proper way. |
C.How to spend more time on working at home. |
D.How to take away time in a much proper way. |

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(蝗蟲(chóng)). 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.[來(lái)源:Zxxk.Com]

Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide produced by burning of coal, oil, wood, together with industrial pollution, are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere and so raising the temperature of the earth.
The evidence for global warming can now be seen in the world’s changing climate statistics. In Europe, eight of the last ten years have seen record high temperature. For northern Europe, this has generally been a change for the better. Gardens can now even grow tropical plants in England, though London may never see a “White Christmas” again. On the other hand, the countries around the Mediterranean Sea, and those south of the Sahara desert are receiving even less rain than before. In sub-Saharan Africa the crops are drying out in the fields and people are dying of starvation. In the Americans, the climate is becoming more extreme—the summers are getting hotter and the storms are becoming more violent. In 1999 the southern United States was struck by a series of destructive hurricanes, while the end of 1999 saw the worst floods ever in Venezuela. Meteorologists expect such trends to continue, and indeed to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and more extreme weather conditions, scientists are closely monitoring sea levels around the world. These are slowly rising, as the northern and southern polar ice-caps start to melt. This will have serious consequences for low-lying countries near the sea, such as the coral islands in the Pacific, and Bangladesh where the River Ganges already floods the delta(三角洲) every year. Already parts of these places are disappearing under the rising tides.
