In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert' s prediction, the atmosphere will be 3℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere (北半球), possibly resulting in an alteration of the earth's chief food growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.
However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and "cold" spots (that is, the relatively less hot spots) on the sun. As the sun rotates (使旋轉(zhuǎn)), every 27. 5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.
Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia (慣性) of the earth's climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat .
It can be concluded that a concentration of carbon dioxide in the atmosphere would_________.
A. mean a warming-up in the Antarctic
B. raise the temperature of the earth' s surface
C. prevent the sun's rays from reaching the earth's surface
D. explain the cause of great changes in the climate in the northern hemisphere
The article was written to explain ___________.
A. the greenhouse effect
B. the solar effects on the earth
C. the causes affecting weather
D. the models of solar-weather interactions
Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is__________.
A. mainly because the levels of carbon dioxide are rising
B. partly due to changes in the output of solar energy
C. possibly because the ice caps in the poles are melting
D. only due to the effect of the inertia of the earth' s climate
On the basis of their models, scientists believe the opinion that__________.
A. the climate of the world should be becoming cooler
B. the new Ice Age will be delayed by the greenhouse effect
C. the man-made warming effect helps to increase the solar effects
D. it will take thousands of years for the inertia of the earth's climate to take effect
If the assumption about the delay of a new Ice age is correct, ____________.
A. ice would soon cover the northern hemisphere
B. the greenhouse effect could work in favor of the earth
C. the best way to overcome the cooling effect would be to burn more fuels
D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly

Twenty-first century humanity has mapped oceans and mountains, visited the moon, and surveyed the planets. But for all the progress, people still don’t know one another very well.
That brings about Theodore Zeldin’s “feast of conversation”－events where individuals pair with persons they don’t know for three hours of guided talk designed to get the past “Where are you from?”
Mr. Zeldin, an Oxford University professor, heads Oxford Muse, a 10-year-old foundation based on the idea that what people need is not more information, but more inspiration and encouragement.
The “feast” in London looks not at politics or events, but at how people have felt about work, relations among the sexes, hopes and fears, enemies and authority, the shape of their lives. The “menu of conversation” includes topics like “How have your priorities(優(yōu)先考慮的事) changed over the years?” Or, “What have you rebelled against the past?”
As participants gathered, Zeldin opened with a speech: that despite instant communications in a globalized age, issues of human heart remain. Many people are lonely, or in routines that discourage knowing the depth of one another. “We are trapped in shallow conversations and the whole point now is to think, which is sometimes painful,” he says. “But thinking interaction is what separates us from other species, except maybe dogs…who do have generations of human interactions.”
The main rules of the “feast”: Don’t pair with someone you know or ask questions you would not answer. The only awkward moment came when the multi-racial crowd of young adults to seniors, in sun hats, ties and dresses, looked to see whom they would be ‘intimate’ with for hours. But 15 minutes later, everyone was seated and talking, continuing full force until organizers interrupted them 180 minutes later.
“It’s encouraging to see the world is not just a place of oppression and distance from each other,” Zeldin summed up. “What we did is not ordinary, but it can’t be madder than the world already is.”
Some said they felt “l(fā)iberated” to talk on sensitive topics. Thirty-something Peter, from East London, said that “it might take weeks or months to get to the level of interaction we suddenly opened up.”
1.What can the “conversations” be best described as?
A．Deep and one-on-one. B．Sensitive and mad.
C．Instant and inspiring. D．Ordinary and encouraging.
2.In a “feast of conversations”, participants ______.
A．pair freely with anyone they like
B．have a guided talk for a set of period of time
C．a(chǎn)sk questions they themselves would not answer
D．wear clothes reflecting multi-racial features.
3.In paragraph 6, “they would be ‘intimate’” is closest in meaning to “______”.
A．they would have physical contact B．they would have in-depth talk
C．they would be close friends D．they would exchange basic information
4.From the passage, we can conclude that what Zeldin does is ______.
A．a(chǎn)n attempt to promote thinking interaction
B．one of the maddest activities ever conducted
C．a(chǎn) try to liberate people from old-fashioned ideas
D．a(chǎn)n effort to give people a chance of talking freely

The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun’s family.
Two of them, Mercury (水星) and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths.
We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional (成比例的) to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed.
Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree.
1.There are ________ that travel around the sun in the sun’s family.
A．nine planets B．eight planets
C．one star and ten planets D．the earth and the sun
2.Which two planets make the longest trips around the sun among all the planets in the solar system?
A．Mercury and Venus. B．Neptune and Pluto.
C．Saturn and Uranus. D．Mars and Jupiter.
3.From the passage we can see__________
A．a(chǎn)ll the objects, big or small, must exert the same pull on one another
B．large objects exert the same pull on anybody as small objects
C．small objects exert the same on large ones
D．each object in the universe exerts a pull on all other objects
4.From the sentence “The pull between two bodies is proportional to the product of their masses.” We can infer that the pull between__________
A．the sun and the moon is greater than between the sun and the earth
B．the earth and the moon is greater than that between the sun and the earth
C．the sun and the earth is greater than that between the earth and the moon
D．the sun and the earth is the same as that between the earth and the moon
