Scientific discoveries have changed man’s life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored.
Scientific discoveries have also changed man’s moral atmosphere. Ethical (伦理的) issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.

举一反三

This is a dangerous world we live in．The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, etc．You know this because you have heard all the statistics on the news and in the paper． But do you really have an accurate idea what they mean? The numbers are growing up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little．
This growing trend of reporting only part of the information is becoming dangerous．For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide．This chemical, found in most cancerous tumors（肿瘤）, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once．After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth．The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background．
The point of this article is that one should be aware of what is and is not being said．When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths．Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view．For example, look again at the statistics that suggest skiing is safe．Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really the most dangerous? If you think about it, you realize far fewer people go skiing each year than the number of people who are in danger of a lightning strike．When you think about it, skiing is more dangerous than you might at first think when looking at statistics．If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s．To be warned is to be prepared．
小题1:In the first paragraph, what problem does the writer want to warn us?

A．We are now living in a dangerous world．

B．We get a lot of false statistics from the media．

C．Statistics alone without full background doesn’t give us an accurate pictures of things．

D．There are around us more and more murders, diseases, etc．

小题2:Why does the writer use the example in the second paragraph?

A．To argue that high school students are easily persuaded．

B．To show the danger of reporting only part of the information．

C．To prove what is necessary to us might be dangerous．

D．To warn us of the harmful substance around us．

小题3:Relative information is often left out because__________．

A．Relative information is not that important．

B．too much information will make readers feel confused．

C．the author is trying to show what he or she says is true．

D．readers are not able to analyze so much information at once．

小题4:What can we learn from the passage?

A．We should learn to think critically and look at problems from all sides．

B．Some measures must be taken to protect our dangerous world．

C．The growing trend of reporting only half-truths is getting out of control．

D．Teenagers ought to improve their ability of telling right from wrong．

(NEW YORK)---Scientists have discovered small signs of awareness in some vegetative(植物人的) brain injury patients and have even communicated with one of them---findings that are beneficial to how to assess and care for such people.
The new research suggests that standard tests may ignore patients who have some consciousness, and that someday some kind of communication may be possible.
In the strongest example, a 29-year-old patient was able to answer yes-or-no questions by picturing specific scenes the doctors asked him to imagine.
“We were stunned when this happened,” said one study author, Martin Monti of the Brain Sciences Unit in Cambridge. “I find it really amazing. This was a patient who was believed to be vegetative for five years.”
Ever since a research paper four years ago described obvious signs of awareness in a vegetative patient, families of patients have been demanding brain scans, said Dr. James Bernat, a spokesman for the American Academy for Neurology.
But experts said more study is needed before the specialized brain scans could be used in medical treatment. “It’s still a research tool,” Bernat said.
Experts also pointed out that only a few tested patients showed evidence of awareness. And they said it is not clear what degree of consciousness and mental abilities the signs imply.
They also noted that the positive signals appeared only in people with traumatic(外伤的) brain injury---not in patients whose brains had been lacking in oxygen, as can happen when the heart stops.
The new study used brain scanning called functional MRI, for 23 patients in a vegetative state and 31 that are minimally(极微地) conscious.
Patients are said to be in a vegetative state if they are tested and found unable to do such things as move on command or follow a moving object with their eyes. Minimally conscious patients show signs of awareness, but they are minimal and discontinuous.
小题1: What is the practical use of the research?

A．It leads to studying how to cure vegetative patients.

B．It attracts society to pay more attention to vegetative patients.

C．It helps doctors know whether patients are vegetative or not.

D．It drives the government to care about vegetative patients.

小题2:What does the underlined word “stunned” in Paragraph 4 probably mean?

A．Relaxed

B．Amazed

C．Excited

D．Worried

小题3:One is considered vegetative if _______________.

A．his eyes can’t follow a moving thing	B．his brain only has a little oxygen
C．he has a traumatic brain injury	D．his heart stops beating

小题4:The passage mainly deals with ________________.

A．how to recognize a vegetative patient	B．the significance of a new scientific finding
C．how family members look after a vegetative patient
D．the latest findings on awareness in some vegetative patients

To switch or not to switch, that is the question．Google’s announcement of its Nexus One smartphone（智能手机） happened over a week ago and I’m still receiving lots of e-mails from readers asking the same question: Should they give up their iPhone for the Nexus One?
Some people with iPhones, disappointed by American Telephone&Telegraph’s inadequate service and the high monthly cost, are wondering if they have really got something to replace it．Does the Nexus One offer the functions that Apple has led them to expect?
I’m on the fence myself, even though I never thought I’d be interested in anything but the iPhone．From my experience using the Nexus One, and from talking to people who have made the change, it’s not necessarily about the differences between the iPhone and the Nexus One．The phones are extremely similar in design and general feel．Instead, the decision can be made based on the software（软件） services you use on your desktop．
My friend Chad Dickerson received a pre-launch Nexus One from Google three weeks ago．He said Google’s phone feels connected to certain services on the Web in a way the iPhone doesn’t．“Compared to the iPhone, the Google phone feels like it’s part of the Internet to me,” he said．“If you live in a Google world, you have that world in your pocket in a way that’s cleaner and more connected than the iPhone．”
Personally, the phones work perfectly with their own software, but both of them don’t make an effort to play well with other services．
小题1:Why are some iPhone users expecting a new type of phone?

A．Because their old ones are out of date．

B．Because they accept Google’s announcement．

C．Because of the limited service and high cost．

D．Because of the terrible software they can use．．

小题2:What’s the author’s attitude towards the new phones in the third paragraph?

A．Negative

B．Neutral

C．Indifferent

D．Positive

小题3:In Chad Dickerson’s opinion, the Nexus One is ________ the iPhone．

A．better than

B．worse than

C．as good as

D．as bad as

小题4:The best title of the passage might be ________．

A．Apple’s New Smartphone

B．Torn Between Two Phones

C．Good Services Matter

D．Google’s New Smartphone

Hungry for the brightest students, many of the country’s stronger universities are actively discounting tuition （学费）．And it’s the high achievers, rather than the needy students, who are getting a good chunk of the money．The practice is remarkably widespread, reaching almost all but the 30 or so Ivy and other top colleges that forbid good grades-based financial aid．Schools are also becoming more aggressive in raising their discounts．At the DePauw University Website, enter an SAT or ACT score, grade point average and class rank, and a computer program immediately tells you what kind of "award"．Only "the real unlucky" pay full price any more．
About 76% of first-year students got some form of discount this year at 331 private schools．Average award per student: $7,000．At small schools with tuition under about $20,000, the average discount is even higher, with some schools returning over half their tuition．
Carnegie Mellon even tells students it will "negotiate（讨价还价）" and perhaps match financial-aid packages if kids are offered bigger awards at other schools．Much as banks and insurers offer special rates to their best customers, schools are giving the biggest breaks to their top students．Public four-year colleges, too, are offering discounts．
The flip side of big discounts is that less money is available to improve academic programs and keep school infrastructure （基础设施） up to date．Universities that have sharply increased their tuition discount rates have seen graduation rates fall, and that’s true even among highly selective schools．They get the students in the door, but don’t have the services to keep them．
小题1:From the first paragraph, we can judge that _______．

A．all the universities don’t offer tuition discounts．

B．Ivy and other top colleges offer financial aid to the high achievers

C．the needy students get more money from the universities

D．the graduation rates of the students from highly selected schools fall

小题2:The underlined words “flip side” in the last paragraph probably mean “_______”．

A．advantage

B．disadvantage

C．bad practice

D．good function

小题3:Which of the following statements is TRUE according to the passage?

A．The brightest students are not at all hungry for stronger universities．

B．About 76% of first-year students got an award of $ 20,000 per year．

C．Public colleges never offer discounts to the students．

D．Colleges should concentrate more on the services to keep the students

小题4:This passage mainly talks about _______．

A．the great benefit of offering lower tuition

B．college tuition discounts in popularity

C．the top students in need of tuition discounts

D．reducing graduation rates due to big discounts

Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
　 But that doesn’t have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
　 Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
　 Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
　 No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.
小题1:What is the real cause of the potentials water crisis.

A．Only half of the world’s water can be used.

B．The world population is increasing faster and faster.

C．Half of the world’s water resources have been seriously polluted.

D．Humanity has not placed enough value on water resources.

小题2:As is indicated in the passage, the water problem _________ .

A．is already serious in certain parts of the world.

B．has been exaggerated by some experts in the field

C．poses a challenge to the technology of building reservoirs(水库)

D．is underestimated by government organizations at different levels

小题3: According to the author, the water price should _______ .

A．be reduced to the minimum	B．stimulate domestic demand
C．go with its real value	D．take into account the occurrences of droughts

小题4:In order to raise the efficiency of the water supply, measures should be taken to ______ .

A．guarantee full protection of the environment

B．centralize the management of water resources

C．increase the sense of responsibility of agencies at all levels

D．encourage local and regional water resources
