-What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技術(shù)). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live, Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.

It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

Everyone knows about straight-A students. We see them frequently in TV situation comedies and in movies like Revenge(報復)of the Nerds. They get high grades, all right, but only by becoming dull laborers, their noses always stuck in a book. They are not good at social communication and look clumsy(笨拙的) while doing sports.

How, then, do we account for Domenica Roman or Paul Melendres?

Roman is on the tennis team at Fairmont Senior High School. She also sings in the choral group, serves on the student council and is a member of the mathematics society. For two years she has maintained A’s in every subject. Melendres, a freshman at the University of New Mexico, was student-body president at Valley High School in Albuquerque. He played soccer and basketball well, exhibited at the science fair, and meanwhile worked as a reporter on a local television station. Being a speech giver at the graduation ceremony, he achieved straight A’s in his regular classes, plus bonus points for A’s in two college-level courses.

How do super-achievers like Roman and Melendres do it? Brains aren’t the only answer. “Top grades don’t always go to the brightest students,” declares Herbert Walberg, a professor of education at the University of Illinois at Chicago, who has conducted major studies on super-achieving students. “Knowing how to make the most of your innate(天生的)abilities counts for more. Much more.”

In fact, Walberg says, students with high IQ sometimes don’t do as well as classmates with lower IQ. For them, learning comes too easily and they never find out how to get down.

Hard work isn’t the whole story, either. “It’s not how long you sit there with the books open,” said one of the many-A students we interviewed. “It’s what you do while you’re sitting.” Indeed, some of these students actually put in fewer hours of homework time than their lower-scoring classmates.

The kids at the top of the class get there by mastering a few basic techniques that others can readily learn.

1.The underlined word “nerds” can probably be________ .

A.dull bookworms lacking sports and social skills

B.successful top students popular with their peers

C.students with certain learning difficulties

D.born leaders crazy about social activities

2.What can we conclude from the first paragraph?

A.Most TV programs and films are about straight-A students.

B.People have unfavorable impression on straight-A students.

C.Everyone knows about straight-A students from TV or films.

D.Straight-A students are well admired by people in the society.

3.Some students become super-achievers mainly because_________ .

A.they are born cleverer than others

B.they work longer hours at study

C.they make full use of their abilities

D.they know the shortcut to success

4.What will be talked about after the last paragraph?

A.The interviews with more students.

B.The role IQ plays in learning well.

C.The techniques to be better learners.

D.The achievements top students make.

5.What can we infer from the passage?

A.IQ is more important than hard work in study.

B.The brightest students can never get low grades.

C.Top students certainly achieve all-around developments.

D.Students with average IQ can become super-achievers.

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.”

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.

2.According to a study of by-standers, what will some people do when a man ahead falls down on the sidewalk?

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.

3.We learn from the last paragraph that if we spot trouble,          

A.we should call the ambulance as soon as we can.

B.we should take on the whole responsibility and do something alone.

C.we should stop and evaluate the situation and try to make other people follow.

D.we should turn to other people and ask them to take on the responsibility

4.In order to offer others your timely help, you need to        

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

5.The main purpose of the text is to tell readers        

A.to give others a hand                    B.to be more competent

C.not to risk looking foolish                 D.to stop and evaluate the situation

As the Internet’s influence grows, the potential for danger also escalates (逐步上升). One of these dangers is from cyber-bullying. Cyber-bullying (網(wǎng)絡欺凌) is repeatedly hurting someone else through the use of technology. It consists of sending or posting cruel messages, photos, or videos on the Internet or other electronic media with the intent of damaging the reputation of the target. Imagine being a 13-year-old girl discovering a cell phone picture of her changing clothes for gym class has been sent to all her classmates. Or imagine being an 11-year-old boy who is scared to go to school because an unknown bully sent him an instant message saying that he is so fat that he should kill himself. Cases such as these are happening every day, leading kids to be depressed and unable to concentrate.
Worse yet, parents are oblivious (忽視的) to what is happening. Only 15 percent of parents even know what cyber-bullying is. And anyone who thinks that their child is not a victim or a bully is probably wrong. 90 percent of middle school students have had their feelings hurt online and 75 percent have admitted to visiting a website attacking another student.
Unlike traditional schoolyard bullying, where a bully has a name and a face, cyber-bullying gets much of its power from anonymity (匿名). A cyber bully might design a website posting cruel remarks about a classmate and never tell anyone that he or she was the creator. The cyber-bullying also gets its power from the scope (范圍) of its audience. Within seconds, a cyber bully can send an e-mail to everyone he or she knows, inviting them to take part in an online poll (民意測驗) of who is the ugliest kid in their class. Victims can be picked on day and night from any place.
The good news is that you can help stop cyber-bullying. By making parents and educators aware of what is going on and encouraging them to take quick and strong action when cyber-bullying cases happen, you can help make technology constructive, not destructive, for young people.

  1. 1.

    What can we learn from the second paragraph?

    1. A.
      Not many students have known of cyber-bullying.
    2. B.
      Parents may not know their child is a victim of cyber-bullying.
    3. C.
      Parents know a lot of cyber-bullying.
    4. D.
      Most of the students have not been hurt by cyber-bullying.
  2. 2.

    What does the author think of the cyber-bullying?

    1. A.
      It is not as harmful as people think.
    2. B.
      It is too complex a problem to settle.
    3. C.
      It will not affect the relationship between classmates.
    4. D.
      It can be stopped through our efforts.
  3. 3.

    What will probably be discussed in the following passage?

    1. A.
      How to prevent cyber-bullying.
    2. B.
      What parents and educators think of cyber-bullying.
    3. C.
      How to make parents aware of cyber-bullying.
    4. D.
      How to make good use of technology.
