The headline of a newspaper presents the heart of the news in brief form. Because of space
limitations head-line writers tend to use short verbs and nouns. Scanning the headlines gives a hasty look at the major news of the day. Headlines are often presented in steps. Each section adds to the news presented in the top headline, If you have only a little time, you may wish to read the headlines and follow up only a few stories you are particularly interested in.
点击查看答案
The first paragraph, or lead of a news story answers certain questions that might be asked by a reader. A lead answers some or all of these questions: "Who？ What？ When？ Where？ Why？ How？" Once again, if you are pressed for time, you can get a great deal of information by reading just the lead.
The news article develops the information presented in the head-line and the lead. News articles are usually written so that paragraphs may be clipped off the end without damaging the story. Since news columns must fit the space provided, putting the most important information at the beginning makes sense. You will not, of course, read every news item every day.
Please give a heading to the passage.
How to read ______.

SECTION 2Optional Translation（30 points) What Is the Force of Gravity？If you throw a ball
SECTION 2 Optional Translation (30 points)
What Is the Force of Gravity？
If you throw a ball up, it will come down again. What makes it come down？ The ball comes down because it is pulled or attracted towards the Earth. The Earth exerts a force of attraction on all objects. Objects that are nearer to the Earth are attracted to it with a greater force than those that are further away. This force of attraction is known as the force of gravity. The gravitational force acting on an object at the Earth's surface is called the weight of the object.
All the heavenly bodies in space like the moon, the planets and the stars also exert an attractive force on objects. The bigger and heavier a body is, the greater is its force of gravity. Thus, since the moon is a smaller body than the Earth, the force it exerts on an object at its surface is less than that exerted by the Earth on the same object on the Earth's surface. In fact, the moon's gravitational force is only one-sixth that of the Earth. This means that an object weighing 120 kilograms on Earth will only weigh 20 kilograms on the moon. Therefore on the moon you could lift weights which are six times heavier than the heaviest weight that you can lift on Earth.
The Earth's gravitational force or pull keeps us and everything else on Earth from floating away to space. To get out into space and travel to the moon or other planets we have to overcome the Earth's gravitational pull.
Entry into Space
How can we overcome the Earth's gravitational pull？ Scientists have been working on this for a long time. It is only recently that they have been able to build machines powerful enough to get out of the Earth's gravitational pull. Such machines are called space rockets. Their great speed and power help them to escape from the Earth's gravitational pull and go into space.
Rockets
The powerful space rocket works along the same lines as a simple firework rocket. The firework rocket has a cylindrical body and a conical head. The body is packed with gunpowder which is the fuel. It is a mixture of chemicals that will bum rapidly to form. hot gases.
At the base or foot of the rocket there is an opening or nozzle. A fuse hangs out like a tail from the nozzle. A long stick attached along the body serves to direct the rocket before the fuse is lighted.
When the gunpowder bums, hot gases or exhaust gases rush out of the nozzle. The hot gases continue to rush out as long as the gunpowder bums. When these gases shoot downwards through the nozzle the rocket is pushed upwards. This is called jet propulsion. The simple experiment, shown in the picture, will help you to understand jet propulsion.

“Two centuries ago, Meriwether Lewis and William Clark left St. Lois to explore the new la
nds acquired in the Louisiana Purchase,” George W. Bush said, announcing his desire for a program to send men and women to Mars. “They made that journey in the spirit of discovery... America has ventured forth into space for the same reasons.”
点击查看答案
Yet there are vital differences between Lewis and Clark’s expedition and a Mars mission. First, Lewis and Clark were headed to a place amenable to life; hundreds of thousands of people were already living there. Second, Lewis and Clark were certain to discover places and things of immediate value to the new nation. Third, the Lewis and Clark venture cost next to nothing by today’s standards. In 1989 NASA estimated that a people-to-Mars program would cost $ 400 billion, which inflates to $ 600 billion today. But the fact that a destination is tantalizing does not mean the journey makes sense, even considering the human calling to explore. And Mars as a destination for people makes absolutely no sense with current technology.
Present systems for getting from Earth’s surface to low-Earth orbit are so fantastically expensive that merely launching the 1,000 tons or so of spacecraft and equipment a Mars mission would require could be accomplished only by cutting health-care benefits, education spending or other important programs or by raising taxes. Absent some remarkable discovery, astronauts, geologists and biologists once on Mars could do little more than analyze rocks and feel awestruck beholding the sky of another world.
It is interesting to note that when President Bush unveiled his proposal, he listed these recent major achievements of space exploration: pictures of the rings of Saturn and the outer planets, evidence of water on Mars and the moon of Jupiter, discovery of more than 100 planets outside our solar system and study of the soil of Mars. All these accomplishments came from automated probes or automated space telescopes. Bush’s proposal, which calls for “reprogramming” some of NASA’s present budget into the Mars effort, might actually lead to a reduction in such unmanned science, the one aspect of space exploration that’s working really well.
Rather than spend hundreds of billions of dollars to hurl tons toward Mars using current technology, why not take a decade or two decades, or however much time is required researching new launch systems and advanced propulsion？ If new launch systems could put weight into orbit affordably, and if advanced propulsion could speed up that long, slow transit to Mars, then the dreams of stepping onto the Red Planet might become reality. Mars will still be there when the technology is ready.
The drive to explore is part of what makes us human, and exploration of the past has led to unexpected glories. Dreams must be tempered by realism, however. For the moment, going to Mars is hopelessly unrealistic.
George Bush’s comparison of Lewis and Clark’s expedition and a Mars mission is mentioned
A．to show that both are of the same and immediate value.
B．to encourage the American people to venture into space.
C．to display the same spirit of discovery in space exploration.
D．to stress that a Mars mission lacks sound and solid basis.

Personal space, an updated form. of Edward T. Hall's 1966 proxemics, is the region surroun
ding each person, or that area which a person considers his domain or territory. Often if entered by another being without this being desired, it makes them feel uncomfortable. The amount of space a being (person, plant, animal) needs falls into two categories, individuate individual physical space (determined by imagined boundaries), and the space au individual considers theirs to live in (often called habitat).
点击查看答案
What distance is appropriate for a particular social situation depends on culture. It is also a matter of personal preference. Personal space is highly variable. Those who live in a densely populated environment tend to have smaller personal space requirements. Thus a resident of India may have a smaller personal space than someone who is home on the Mongolian steppe, both in regard to home and individual.
Personal space can be determined on a habitat level by profession, livelihood, and occupation. It can also be heavily affected by a person's position in society, with the more affluent a person being the larger personal space they demand. While it is highly variable and difficult to measure accurately the best estimates for personal physical space place it at about 24.5 inches (60 centimeters) on either side, 27.5 inches (70 centimeters) in front and 15.75 inches (40 centimeters) behind for an average westerner.
In certain circumstances people can accept having their personal space violated. For instance in romantic encounters the stress from allowing closer personal space distances can be reinterpreted into emotional fervor. Another method of dealing with violated personal space, according to psychologist Robert Sommer, is dehumanization. He argues that, for instance on the subway, crowded people imagine those infiltrating their personal space as inanimate. Changing perceptions about personal space and the fluctuating boundaries of public and private in European culture since the Roman Empire have been explored in "A History of Private Life", under the general editorship of Philippe Aries and Georges Duby, published in English by the Belknap Press.
Which of the following is NOT true？
A．Personal space means the space one occupies as a resident.
B．The research of personal space originated from promexics.
C．Not only human beings need personal space.
D．Imagined boundaries and habitat consist one's need of personal space.

听力原文：What is the shape of the universe？ The question has baffled and obsessed humankin
听力原文： What is the shape of the universe？ The question has baffled and obsessed humankind since civilization first gazed up towards the heavens. The world has yet to receive a satisfactory explanation. Now a new study hints at a possible answer. Contrary to the traditional interpretation, the study suggests the universe is finite and bears a rough resemblance to a soccer ball, or to put it more accurately, the universe looks like a 12-sided volume bounded by pentagons. Based on the new theory, a model has been made to help illustrate the alleged shape of the Universe. If proven by further evidence and inspection, the model would represent a major discovery about the nature of the cosmos.
"What makes the discovery exciting now is it's not a matter of idle speculation," said Jeffrey Weeks, a US mathematician, "There's real data to look at and there's the great possibility of getting a definite answer." Weeks has announced hints that the Universe is actually relatively small, with a hall-of-mirrors illusion which tricks us into thinking that the space stretches on forever.
While studying cosmic background radiation observed by NASA's Wilkinson Microwave Anisotropy Probe, Jeffrey Weeks, together with a team of French cosmologists, arrived at this new discovery. It is still in question whether the theory is correct. However, the idea itself is indeed appealing and inspiring.
(26)
A．A new discovery in Mathematics.
B．A new program conducted by NASA.
C．A new theory on the shape of the universe.
D．A new planet detected in space.
