(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．RelaxedB．AmazedC．ExcitedD．Worried
小题3:One is considered vegetative if _______________.
A．his eyes can’t follow a moving thingB．his brain only has a little oxygen
C．he has a traumatic brain injuryD．his heart stops beating
小题4:The passage mainly deals with ________________.
A．how to recognize a vegetative patientB．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
Drunken driving –sometimes called America’s socially accepted form of murder—has become a national epidemic (流行病). Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts, but the drunken killing has recently caused so many well-publicized tragedies, especially concerning young children, that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20 years old drivers more than doubled, so the state recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop “responsible attitudes” about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests in many areas already, to a marked drop in accidents, some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was “obviously drunk” and later drove off the road, killing a 9-year-old boy.
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years national prohibition of alcohol that began in 1919, which President Hoover called the “noble experiment”. They forgot that legal prohibition didn’t stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.

This is the age of being busy．Many of us live in busy places and have busy lives．Even the roads are busy as we try to get from here to there．Adults are busy going to jobs and taking care of their families．Kids are busy，too，going to school and doing lots of homework after school and on weekends．
Busy isn’t bad，necessarily．If you’re not busy enough you might be bored．But if you’re too busy．you might break down．For instance，if you have a soccer game that runs late on a school night and you haven’t eaten dinner or done your homework．that’s a not—so—fun kind of busy．We wanted to know what kids thought，so we did a KidsPoll about being busy with 882 girls and boys aged 9 to 1 3．
Almost all of them said they felt stressed because they were too busy．About half said they felt this way once in a while or some of the time．But l 7％said they felt this way most of the time and 24％said they felt like this all the time! Oh dear，that’s no fun．
Only 4％of kids said they wanted less free time and l8％said they already had just the right amount．But，no big surprise，61％of kids wish they had a lot more free time．If they had more time．most would spend it hanging out or playing with friends．
Often，adults plan large parts of a kid’s day，especially during the school year．Kids can’t tell their parents they’ll be skipping school(逃学)today to get more free time!But they can tell their parents they’d like to play a game or read a book during their free time instead of watching TV．
小题1:．The purpose of the first paragraph is to
A．introduce the topic B．support the main idea

小题2:．According to the passage，the Kidspoll is done to carry out research on
A．how kids arrange their free timeB．what kids think of being busy
C．how many kids felt stressed D．what kids do with fheir study
小题3:．According to the KidsPoll，what conclusion can we draw?
A．91％of the kids think being busy is no fun．
B．22％of the kids don’t need more free time．
C．61％of the kids spend free time playing．
D．24％of the kids like the busy way．
小题4:．From the passage，we can infer that the writer agrees kids can
A．spend their free time hanging or playing out
B．get a lot more free time from their parents
C．have a right amount of free time with permission
D．get more free time from school work sometimes
The United States is full of cars. There are still many families without cars, but some families have two or more. However, cars are used for more than pleasure. They are a necessary part of life.
Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.
Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile away from the school. When the children are too young to walk too far, their mothers take turns driving them to school. One mother drives on Mondays taking her own children and the neighbors' as well. Another mother drives on Tuesdays, another on Wednesday, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.
More car pools should be formed in order to put fewer cars on the road and use less gas. Too many cars are being driven. Something will have to be done about the use of cars.
小题1: The United States is filled with cars, but             .
A．not every family has a car B．few families have two cars or even more

     Each new school year brings fresh reminders of what educators call the summer learning gap．Some call it the summer learning setback Put simply, it means the longer kids are out of school，the more they forget．The only thing they might gain is weight．
Most American schools follow a tradltional nine-month calendar with winter and spring breaks and about ten weeks of summer vacation．Some schools follow a year-round calendar. They hold classes ror about eight weeks at a time，with a few weeks off in between．The National Association for Year-Round Education says there were fewer than 3,000 such schools at last count．They were spread among forty-six of the tifty states．
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school．Brenda McLaugblin is research director at the National Center for Summer Learning at Johns Hopkins University．She says studies of year-round schooling have not found strong learning gains．Lead researcher Paul von Hippel said，“Year-round schools don’t really solve the problem of the summer learning setback．They simply spread it out across the year．”
Across the country, research shows that students from poor families fall farther behind over the summler than other students．Experts say this can be prevented．They note that many schools and local governments offer programs that can help．
But calling them“summer school”could be a problem．The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term“summer school”．In American culture，the idea of summer vacation is connected to beliefs about freedom and the joys of childhood．The parents welcomed other terms like“summer camp。”“extra time”and“hands-on learning．”
小题1:According to the first paragraph，the summer learning gap     
A．helps children to gain weight

小题3:Which of the following statements is true?
A．Students from poor families often fall behind after the vacation．
B．Year-round schools can solve the problem of the learning gap
C．There are schools in each state following a year-round calendar

D．Reforming Year-Round Education
People who traveled in the past had to put up with many discomforts which we do not have nowadays, and of course they traveled far more slowly. Roads were bad indeed and you often found you could not get along at all because of the mud. In dry weather many places were thick in dust and when it was stormy, trees might fall across the road and it was nobody’s business to clear them away.
Ordinary people traveled on foot or on horseback, but everyone who could afford it kept a private coach. There were public coaches too. called “stage coaches” because long journeys took several days and were done in stages, with stops over night at inns. Some stage, coaches ran only in the summer months. Others all the year around. They were very slow and crowded and passengers often became in on the way because of the swaying (摇晃).
Break downs were frequent, since many roads were not smooth. So a coach might very easily turn right over. Early in the century coach and wagon builders were encouraged to put very wide wheels on their vehicles. So that these might level the roads a little. But many people complained of this since it slowed travel down a good deal.
Most travelers during the 18th century wrote bitterly about the state of the roads. One visitor to Sussex took six hours to travel nine miles in his coach; another wrote to a friend that on time of his journeys “almost every mile was marked by the overturn of a carriage”.
小题1:Which of the following mainly prevented people from travelling fast in the past?
A．Falling treesB．Thick dust
C．Muddy roadD．Many discomforts
小题2: The underlined word “them” in the first paragraph refers to _____.
A．the discomfortsB．the blocked roads
C．the dusty placesD．the fallen trees
小题3: Public coaches were called “stage-coaches” because ______. 
A．the long journey was broken into several parts
B．they were slow and crowded
C．they stopped for meals at inns
D．they served public people only
小题4: The sentence “almost every mile was marked by the overturn of a carriage” suggests that ______.
A．the coaches were of poor quality
B．the writers liked to describe the road bitterly
C．the road condition was really poor
D．travelling about in the past was extremely slow
School violence is in the headlines again after recent shootings at schools in Pennsylvania, Wisconsin, and Colorado. After hearing the news, it’s natural for students — no matter how old they are or where they go to school — to worry about whether this type of incident may someday happen to them.
So how safe are schools? It’s actually safer to be in a school than in a car. Twice as many 15-to-19-year-olds die in car accidents than in shootings (and that’s all shootings, not just the ones that happen in schools). According to the Centers for Disease Control and Prevention, less than 1% of all homicides (杀人罪) among school-age children happen on school grounds or on the way to and from school. So the vast majority of students will never experience violence at school.
However, some schools have re-evaluated their safety needs in response to the concerns of families and communities. Some now require that guests check in at the office or have more guards on duty. Some schools have fixed metal detectors. Another thing that helps make schools safer is greater awareness of problems like bullying and discrimination. Many schools have practiced programs to fight these problems and to help teachers and administrators know more about protecting students from this type of violence.
The cause of school violence isn’t easy to understand. There is no single reason why students become violent. Some are just copying behavior they’ve seen at home, in the streets, or in video games, movies, or television. There’s one thing experts do agree on, though: Having access to guns or other weapons makes it easier for some people to lash out against the things or people they don’t like.
小题1:Which of the following statements can prove that schools are safe?
A．About 99% of 15- to-19-year-olds are safe at school.
B．Fewer students have died in car accidents than in shootings.
C．Students shot to death at school are half of all students.
D．Fatal shootings of students are less than 1% of all homicides.
小题2: After schools have re-evaluated their safety needs, ________.
A．families will be more concerned about schools
B．communities will be responsible for schools
C．teachers will pay more attention to shootings
D．administrators will arrange to have more guards on duty
小题3:From the last paragraph we can conclude that ______.
A．experts have found no reason for school violence
B．students with weapons are easily upset about things
C．school violence could be copied from violence in society
D．no single reason makes students violent
小题4:We could probably see this passage in ______.
A．an analysis reportB．a realistic novel
C．a case investigationD．a news journal
Many businesses today use conferences as a means of discussing new plans for company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It is an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a web conference will be posted an invitation to the conference with the time and date of the web conference on it. When the conference is ready to begin, all participants (参与者) must sit at their computer and they will be connected over the Internet.
Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.
Any material to be used during the web conference is simply e-mailed to all the participants before the conference. This not only saves paper but also greatly reduces mailing cost for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal computers. Similarly conference organizers don’t have to arrange for food or overnight accommodation (住宿) for participants. All this means that less energy is used.
Many companies actively do many things to reduce their negative impact (影响) on the environment. So web conferencing is much cheaper and greener and more people are willing to host and attend a web conference.
小题1:What is the passage mainly about?
A．Ways of protecting the environment.
B．Green benefits of web conference.
C．Ways of hosting a web conference.
D．Impacts of web conferencing on costs.
小题2:According to paragraph 1, many companies use web conferencing because they________.
A．are interested in using any new technology
B．believe that web conferencing is more convenient
C．want to do something to protect the environment
D．haven’t enough money to hold a traditional conference
小题3:Web conferencing has all of the following advantages EXCEPT _________.
A．saving timeB．promoting understanding
C．saving energyD．saving paper
小题4:The participants of a web conference_________.
A．will be e-mailed an invitation before the conference
B．are required to sit in the office together
C．will receive many paper materials
D．must have access to the Internet
