(NEW YORK)---Scientists have discovered small signs of awareness in some vegetat
题型：不详难度：来源：
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.

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．． |
| A．Negative | B．Neutral | C．Indifferent | D．Positive |
| A．better than | B．worse than | C．as good as | D．as bad as |
| A．Apple’s New Smartphone |
| B．Torn Between Two Phones |
| C．Good Services Matter |
| D．Google’s New Smartphone |
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 |
| A．advantage | B．disadvantage | C．bad practice | D．good function |
| 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 |
| 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 |
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. |
| 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 |
| A．be reduced to the minimum | B．stimulate domestic demand |
| C．go with its real value | D．take into account the occurrences of droughts |
| 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 |
Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast (抨击) the use of emoticons as “infantile (幼稚的) just like the people who use them” He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent (明显的) from the comment that goes before the emoticon,” he argues.
In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’ s an emoticon gene.”
It’s an interesting opinion, but it is not shared by all.
In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (融入) something beyond language. They reach to our need to be with and communicate with people.
All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking.
Friends, however, send me messages and e-mails full of emoticons. I have no problem with this. I don’t regard any of my friends as lazy or immature (不成熟的). It’s just a question of individuality. :)
小题1:According to the article, emoticons are popular because ______.
| A．most of them look funny |
| B．they are easy for lazy people to use |
| C．they add feeling and character to a communication |
| D．a reader cannot understand a message without them |
| A．Instant Message chatters are childish. |
| B．It’s enough to use language in digital communication. |
| C．Men never use emoticons. |
| D．There is an emoticon gene in everybody. |
| A．feels he has no difficulty using emoticons |
| B．thinks emoticons don’t suit him |
| C．encourage his friends to use emoticons |
| D．believes that emoticons are suitable for everyone |
| A．Advice on language used over the Internet. |
| B．The history of emoticons. |
| C．Arguments over the use of emoticons. |
| D．Reasons for the popularity of emoticons. |
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown"s business and engineering schools．They began thinking about ways to sleep better．They discovered they weren"t alone in burning the midnight oil．Around 20% of Americans get less than six hours of rest a night．
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative （有回复作用的） stages of the sleep cycle: REM （rapid eye movement） and deep sleep．What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors a
nd scientists．Their company, Zeo, based in Newton, Mass, launched its product in June, 2009．The Zeo device uses a headband with tiny sensors （传感器） that scan your brain for signs of four sleep states- REM, light, deep and waking sleep．The smart alarm clock displays a graph of your sleep pattern and wakes you as you"re not in REM sleep （which is when you"re least groggy）．In the morning you can upload the data to the company"s Web site, and so track your sleep over time．Most of the feedback comes in the form of Zeo"s ZQ score showing how well you"ve slept．
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO．
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm．
For now the company is selling Zeo online only．Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels．
小题1:Who will support Zeo?
| A．People full of imagination． | B．People suffering sleeping problems． |
C．P eople having access to the Internet． | D．People having bad lifestyles． |
| A．To wake them up on time in the morning． |
| B．To earn enough money for their study． |
| C．To improve the quality of people"s sleep． |
| D．To enjoy their life while working at night． |
| A．spent much time and money | B．were widely supported by scientists |
| C．worked by themselves all the time | D．attracted many investors |
| A．Zeo has a direct effect on users" lifestyles． |
| B．It needs more personal efforts to make Zeo function better． |
| C．A large quantity of Zeo devices have been sold in Australia． |
| D．Consumers can go to the Zeo company to purchase Zeo in person． |
