Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因構(gòu)成) as human beings.What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of' a species, the better its chance of' survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible. Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential(潛在的) resources to be found.Even if' we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration.The techniques may have medical applications which can improve the length or quality of our lives.We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副產(chǎn)品) of technological developments in the space.
While many resources are spent on what seems a small return, the exploration of' space us.While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

閱讀下面的短文,并根據(jù)短文后的要求答題(請(qǐng)注意問題后的字?jǐn)?shù)要求)。
[1]Everyone makes mistakes. How do you react when a family member, friend, or a classmate makes a mistake? Some of us may shout out , complain, or punish. Unfortunately, these reactions to mistakes sometimes greatly hurt both sides. In fact, there is a better way to deal with a mistake.
[2]Reframe(重組) "MISTAKE": Change "MISTAKE" into "MIS-TAKE." Doesn't that have a different feeling? Therefore, a mistake is not so bad as expected. We can learn from it and it is likely to lead to success in the end.
[3]Use mistakes as an opportunity for learning. Most of us want to hide our mistakes, but we may be more willing to share our "MIS-TAKES" and let others learn from them. Either an individual or a family can benefit by openly recognizing and correcting mistakes, rather than pretending that they didn't happen. In fact, a mistake, if corrected quickly and in a creative way, can become ___________for learning.
[4]Think of mistakes as opportunities to prove yourself. A mistake becomes an opportunity to create a close friend or customer. For example, in business, studies show that one of the things all customers want is recovery when the organization has made a mistake. They want us to apologize sincerely. With creative thinking, we can make them satisfied with the way we deal with a mistake.
[5] We have learned to allow people around us to make mistakes. Now give them “protection” when they make a mistake. If you give people both permission and protection, you will get along well with them. Show them how they can turn a mistake into learning something about themselves so they don’t make the same mistake again.
【小題1】What is the passage mainly about? (no more than 10 words)
___________________________________________________________ _____
【小題2】What does the underlined word “it” in Paragraph 2 probably refer to? (no more than 3 words)
___________________________________________________________ _
【小題3】Fill in the blank in Paragraph 3 with proper words.(no more than 4 words)
__________________________________________________________
【小題4】Complete the following statement with proper words.(no more than 3 words)
If we think creatively, we are able to make people feel pleased with the way in which a mistake is_________________.
【小題5】Why should you show people how to turn a mistake into learning something about themselves ? (no more than 12 words)

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s.
In the same way, children are learning to do all the other things: they learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(常規(guī)) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to judge their own understanding, and how to know what they know or do not know.
【小題1】The first paragraph is written mainly to _________.
A.give advice on children’s language learning |
B.tell us the fewer mistakes we correct, the better children will learn a language |
C.suggest children are often too stubborn to accept advice |
D.lead to the topic of the passage |
A.Give children correct answers. |
B.Allow children to make mistakes. |
C.Point out children’s mistakes to them. |
D.Let children mark their own work. |
A.a(chǎn)llow children to learn from each other |
B.point out children’s mistakes whenever found |
C.give children more book knowledge |
D.correct children’s mistakes as soon as possible |
A.listening to skilled people’s advice |

You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved.
“There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.
● Why should I be the one? I’m probably not the most competent(有能力的)person in this crowd. You might think someone older or with more medical knowledge should offer assistance.
● What if he doesn’t really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.
● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public.
“If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”
【小題1】Which is NOT the common thought that stops you from helping others?
A.I’m not the very person capable of setting the problem. |
B.It looks like we should do something. |
C.It must not be a problem as no one else is concerned. |
D.He doesn’t really need my help. |
A.They will call for help and then walk away. |
B.They will stop and offer help. |
C.They will turn away their eyes and go on walking. |
D.They will laugh at him. |
A.we should call the ambulance as soon as we can |
B.we should stop and evaluate the situation and try to make other people follow |
C.we should take on the whole responsibility and do something alone |
D.we should turn to other people and ask them to take on the responsibility |
A.a(chǎn)sk others for help and call the police |
B.get along well with the passers-by who spot the trouble |
C.go directly to the police station |
D.work against the first thoughts that prevent you offering help |
A.to give others a hand |
B.to be more competent |

Long before the white man came to the America, the land belonged to the American Indian nations, The nation of the Cherokees lived in what is now the southeastern part of the United States.
After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing was to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible; there were just too many words. Then he took the 85 sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper.
In 1830, the US congress passed a law. It allowed the government to remove Indians from their lands. The Cherokees refused to go. They had lived on their lands for centuries. It belonged to them. Why should they go to a strange land far beyond the Mississippi River?
The army was sent to drive the Cherokees out. Soldiers surrounded their villages and marched them at gunpoint into the western territory. The sick, the old and the small children went in carts, along with their belongings. The rest of the people marched on foot or rode on horseback. It was November, yet many of them still wore their summer clothes. Cold and hungry, the Cherokees were quickly exhausted by the hardships of journey. Many dropped dead and were buried by the roadside. When the last group arrived in their new home in March 1839, more than 4000 had died. It was in deed a march of death.
