While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA

举一反三
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
小题1:Watchers doubted if any of the vehicles could finish the race because .
| A．they did not have any human guidance |
| B．the road was not familiar to the drivers |
| C．the distance was too long for the vehicles |
| D．the prize money was unattractive to the drivers |
| A．raise money for producing more robotic vehicles |
| B．push the development of vehicle industry |
| C．train more people to drive in the desert |
| D．improve the vehicles for future wars |
| A．can do effortlessly whatever tasks living thing can |
| B．can take part in a race across 142 miles with a time limit |
| C．can show off their ability to turn themselves upside down |
| D．can move from place to place without being driven by human beings |
| A．about eight miles | B．six miles |
| C．almost two miles | D．about one mile |
| A．for a robotic vehicle to finish a 142-mile race without any difficulties |
| B．for a little child who has just learned to walk to reach the cookie on the table |
| C．for a robotic vehicle to deal with a simple problem that a little child can solve |
| D．for a little child to understand the importance of wiping apple juice off its face |
None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth"s surface. They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes andtested. Each small part was examined to learn whether there were minerals in it.
Study of the roots, branches and seeds showed no silver. But there were small amount of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.
If the trees indicated that there was no gold in the ground, the scientists wouldn"t spare money to pay for digging into the ground.
小题1:Scientists were flying over a desert or a hilly wasteland or a mountain region to ________.
| A．train their eyes | B．study the trees | C．look for gold | D．search for minerals |
| A．there were larger amounts of gold in the branches far from the tree trunk than in the seeds |
| B．there were smaller amounts of gold in the tree roots deep in the ground than in the branches |
| C．there were larger amounts of gold in the seeds growing closer to the tree trunk than in the seeds farther from it |
| D．there were larger amounts of gold in the branches than in the leaves on the ends of the branches |
| A．Leaves. | B．Roots. | C．Branches. | D．Seeds. |
| A．Scientists searching for treasure with special equipment. |
| B．New methods of doing geological study. |
| C．Gold could be found in trees and plants. |
| D．A new method of searching for minerals. |
George F．Madaus and his colleagues at Boston College analyzed not only the six most widely used national standardized tests， but also the tests designed to accompany（go with）the four most commonly used science and math texts in fourth-grade，eighth-grade，and high-school classrooms．Though curriculum（teaching program）experts argue that schools should place greater emphasis on problem solving and reasoning， the new study shows that the tests focus on lower-level skills—primarily mechanical memorization of routine formulas（公式）．
Researchers surveyed more than 2，200 math and science instructors，interviewing in depth some 300 teachers and administrators．Especially in schools with high minority enrollments，teachers reported feeling pressured to help students perform well on these tests．Some states judge schools and some schools determine teacher assignments（工作安排）based on students" test scores．
“With so much worry，”Madaus says，“teachers feel forced to focus their instruction on drilling what the tests will measure—at the expense of the more valuable，higher-level skills．”
小题1:The author of this article states that ____ _ ．
| A．the tests don"t affect teaching in most elementary and high schools |
| B．the science and math teaching is influenced by the present tests |
| C．no study is performed on tests for the National Science Foundation |
| D．the United States exerts a strong influence on science and math teaching |
| A．the students can not get high score from the tests |
| B．scores from the tests are not important |
| C．instructional emphases are unfavourable |
| D．teaching doesn"t focus on the quality of education |
| A．emphasis of teaching is on problem solving and reasoning |
| B．curriculum is good for national standardized tests |
| C．the tests mainly center around the memorization of some formulas |
| D．routine formulas are not useful for students to memorize |
| A．evaluate（评估）students" skills every year |
| B．suffer so much worry on the texts |
| C．teach what will be tested |
| D．focus their instruction on useful drillings |
Remember your mother’s age. As children, we often do not think of our mother as having an age. Even when we become conscious of her as an individual, age does not change our view; she is still our mother. Knowing our mother’s age, not just in numbers of years but in terms of her psychological and physical state, often helps us to understand her better.
Listen to your mother. I have found that sometimes the things my mother told me long ago are remarkably useful. If your mother knows that you respect her point of view, even if you do not share it, it will help her feel close to you.
Remember that your mother has a past. A key step in managing our relationship with our mother is to find out about her early life. Niclle’s mother suffered much during the Second War World War. “My parents are both Jewish-Turkish. They met in France and married young for love. They were in their twenties when war broke out and because they were Jews, they had to go into hiding. She does speak to me about the war, and I think it is important to know what she went through. It is a part of her life that must have affected her deeply. ” Sometimes, in learning about our mother’s past, we know that it can encourage us to think about her whole life.
Ask your mother about your childhood history. My grandparents died when I was young. If you are fortunate enough to have living family, think of your life as a jigsaw puzzle and ask as many questions as you can to put the picture together. Understanding your roots and your childhood can help you now more clearly who you are, as part of a family which you share with your mother.
Keep a sense of humor about your mother. When we hear about someone else’s misfortunes with their mothers and are amused by them, our laughter is one of recognition. I have often listened to stories of difficult mothers and I have also listened to the following piece of advice they have found most helpful is: “Don’t have a sense of humor failure about your mother. ”
Remember that managing your mother is really about managing yourself. Taking any measure to managing our mother is the issue of how we manage ourselves. No matter how difficult we find her, it is important to remember that is not her behavior it self that is causing us discomfort, but the way we feel about her behavior. We should follow the way of her life. At the heart of managing your mother is being able to accept your flawed self. Only then are you able to accept your mother—-with all her failings.
小题1:The followings are the steps you can take to get on with your mother EXCEPT________.
| A．Remember your mother’s age and past |
| B．Share your roots and your childhood with your mother |
| C．Have a sense of humor failure about your mother |
| D．Managing your shortcoming while managing your mother |
| A．拼图玩具 | B．浏览迷宫 | C．填充字谜 | D．游戏人生 |
| A．It will help you have a better relationship with your mother if you respect her opinion. |
| B．You should follow a most useful piece of advice——a sense of humor. |
| C．The key measure of managing our mother is how we manage ourselves. |
| D．It is unreasonable to expect our mother to change totally from the way she was brought up. |
| A．to give information about how we think of your mother. |
| B．to improve the relationship with your mother. |
| C．to keep a sense of humor about your mother all day long. |
| D．to accept your mother—-with all her failings. |
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!
小题1:When the star begins to die ______.
| A．there is no fuel left in it | B．its outer layer goes into space first |
| C．a huge explosion will happen | D．it doesn’t give off light any longer |
| A．The gravity inside the star is very strong. | B．The light can’t go out of the star. |
| C．The star becomes smaller and smaller | D．The dying star shines very brightly. |
| A．continues becoming smaller and smaller all the time |
| B．goes into another universe and becomes a white hole |
| C．can pull in everything we know of in the world |
| D．will appear at another place at a different time |
| A．A New Scientific Discovery: Black Holes |
| B．How Do Black Holes Come Into Being? |
| C．What Are Black Holes? |
| D．Travel Through A Black Hole |
