Do you want to live forever? By the year 2050,you might actually get your wish-if you are willing to leave your biological body and live in silicon circuits (半导体电路). But long before then, perhaps as early as 2020,some measures will begin offering a semblance of immortality (虚的永生).　　

Researchers are confident that the technology will soon be able to track every waking moment of your life? Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your　 personal chronicles (履历). By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.

Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to microseosors under your scalp (头皮) and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.

At first, the Soul Catcher's companion system-the Soul Reader-might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities (永生实体). Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.

For people who choose not to live in silicon, semblance of immortal it would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.

1.The main idea of this passage is that_____ .

A. human beings long for living forever

B. there are many difficulties in making the Soul Catcher

C. people can live forever as technology develops

D. the invention of Soul Catcher has great importance

2.According to this passage, a Soul Catcher will be______ .

A. a new machine on which research measures have already been made

B. a new invention in order to catch and keep human's thoughts

C. made by British scientists to offer something that looks like living forever

D. made of silicon circuits which can catch people's nervous activity

3.We can infer from the passage that semblance of immortality is______.

A. to be a reality sooner or later

B. far from certain

C. just an idea that couldn't be realized at all

D. a fading hope

4.The meaning of the underlined word revitalize, in the fourth paragraph is close to___　　 .

We are all faced with challenges constantly in every area of our lives.　 1 The truth is that you will have to deal with difficult problems throughout your life, whether it is in your personal life or career. Most of us get really afraid and run away from problems because we don’t want to accept reality. Running away from your problems is the worst thing you can do to deal with the challenges you are faced with. Here are some tips for you on learning how to deal with everyday challenges.Please bear in mind that you shouldn’t overact when coming across challenges. Overacting to a problem will cause you to make bad decisions. 2　 Next time you are faced with a challenge, stay calm so you can make smarter decisions.　 3　 If you cannot accept reality, you will feel very frustrated with your life. Once you can accept reality, you will be able to be calmer and think more clearly about how to get a step closer towards your goals every day.Many people make a habit of blaming others for all their problems. They fail to take full responsibility for the decisions they have made in life. The more you blame others for the challenges you are faced with, the more you will make people dislike you and not want to be around you.　 4 Don’t compare your lifestyle with others. Of course, it is really difficult not to compare ourselves with other people. However, the more often we do that, the more frustrated we will feel. 5 The key thing to remember is that you create your own story and success in life.

If you’ve spent any amount of time boating, fishing, or bird-watching at lakes and rivers, you have most likely seen fishes jumping out of the water. I have seen it many times. Certainly, fishes will exit water in desperate attempts to escape enemies. Dolphins take advantage of the behavior, forming a circle and catching the frightened fishes in midair. But just as we may run fast from fun or from fear, different emotions might motivate fishes to jump.

Mobula rays (蝠鲼) aren’t motivated by fear when they throw their impressive bodies — up to a seventeen-foot wingspan (the distance from the end of one wing to the end of the other) and a ton in weight — skyward in leap of up to ten feet. They do it in schools of hundreds. They usually land on their bellies, but sometimes they land on their backs. Some scientists think it might be a way of removing parasites (寄生虫). But I think that the rays are enjoying themselves.

In the clear waters of Florida’s Chassahowitzka National Wildlife Refuge, I watched several schools of fifty or more mullets(鲻鱼) moving in beautiful formation. Their well-built bodies were most evident when they leaped from the water. Most of the time I saw one or two leaps by a fish, but one made a series of seven. They usually land on their sides. Each jump was about a foot clear of the water and two to three feet in length.

Nobody knows for sure why the fish leaps. One idea is that they do it to take in oxygen. The idea is supported by the fact that mullets leap more when the water is lower in oxygen, but is challenged by the likelihood that jumping costs more energy than is gained by breathing air. It is hard to imagine they will feel any fresher when back in water.

Might these fishes also be leaping for fun? There is some new evidence. Gordon M. Burghardt recently published accounts of a dozen types of fishes leaping repeatedly, sometimes over floating objects — sticks, plants, sunning turtle — for no clear reason other than entertainment.

1.What can we say about the dolphins in Paragraph 1?

A.They have great escaping skills. B.They are easily frightened.

C.They are very clever. D.They love jumping.

2.What do the ray and the mullet have in common when jumping?

A.Both do it in groups. B.Both land on their bellies.

C.Both jump many feet out of water. D.Both make leaps one after the other.

3.What’s the author’s attitude towards the idea mentioned in Paragraph 4?

A.Anxious. B.Indifferent.

C.Approving. D.Questionable.

4.Why do fishes leap according to Gordon?

A.To remove parasites. B.To amuse themselves.

C.To take in more oxygen. D.To escape enemies.

If you think that running marathons will help you live a long and healthy life，new research may come as a shock．According to a recent scientific study，people who do a very strenuous workout are as likely to die as people who do no exercise at all．

Scientists in Denmark have been studying over 1，000 joggers（慢跑者） and non-joggers for 12 years．The death rates（率） from the sample group suggest that people who jog at a moderate(适合的) pace two or three times a week for less than two and a half hours in total are least likely to die．

The best speed to jog at was found to be about 5 miles per hour．The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers．The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉)．Over time，this can cause serious injuries．

Peter Schnohr，a researcher in Copenhagen，said，“If your goal is to decrease（减少） risk of death and improve life expectancy，jogging a few times a week at a moderate pace is a good strategy（策略）．Anything more is not just unnecessary，and it may be harmful．”

The implications（含义） of this are that moderate forms of exercise such as tai chi，yoga and brisk walking may be better for us than “iron man” events，triathlons（三项全能） and long-distance running and cycling．According to Jacob Louis Marott，another researcher in the study，“You don’t actually have to do that much to have a good impact（影响） on your health．And perhaps you shouldn’t actually do too much”．

1.The underlined word “strenuous” in Paragraph l is closest in meaning to“___________”．

A．hard　　　　　　　　 B．regular

C．practical　　　　　 D．flexible（灵活的）

2.The author presents some figures in Paragraph 2 to ___________．

A．suggest giving up jogging

B．show risks of doing sports

C．provide supportive evidence（证据）

D．introduce the research process（过程）

3.According to the scientists，why is too much exercise harmful？

A．It may injure the heart and arteries．

B．It can make the body tired out．

C．It will bring much pressure．

D．It consumes too much energy．

4.What can be inferred from the text？

A．No exercise at all is the best choice．

B．More exercise means a healthier life．

C．Marathons runners are least likely to die．

D．Proper exercise contributes to good health．
