     WASHINGTON -According to statistics compiled by the Federal Bureau of Investigation,
72 officers were killed by criminals in 2011, increased markedly in recently years.
     The 2011 deaths were the first time that more officers were killed by suspects than car accidents.
The number was the highest in nearly two decades, excluding those who died in the Sept. 11 attacks
in 2001 and the Oklahoma City bombing in 1995.
     While the F.B.I. and other law enforcement(执行) officials cannot fully explain the reasons for the
rise in officer homicides, they are clear about the terrible consequences.
     "In this law enforcement job, when you pin this badge on and go out on calls, when you leave
home, you can't guarantee that you will come back," said Sheriff Ray Foster of Buchanan County,
Va.
     After a series of killings in early 2011, Attorney General Eric H. Holder Jr. asked federal authorities
to work with local police departments to try to come up with solutions to the problem.
      The F.B.I., which has tracked officer deaths since 1937, paid for a study conducted by John Jay
College that found that in many cases the officers were trying to arrest or stop a suspect who had
previously been arrested for a violent crime.
     That prompted the F.B.I. to change what information it will provide to local police departments,
the officials said. Starting this year, when police officers stop a car and call its license plate into the
F.B.I.'s database, they will be told whether the owner of the vehicle has a violent history. Through the
first three months of this year, the number of police fatalities has dropped, though it is unclear why.
     Some law enforcement officials believe that techniques pioneered by the New York Police
Department over the past two decades and adopted by other departments may have put officers at
greater risk by encouraging them to conduct more street stops and to seek out and confront (对抗)
suspects who seem likely to be armed. In New York and elsewhere, police officials moved more
officers into crime-ridden areas.
     Some argue that the rise in violence is linked to the tough economy. With less money, police
departments, after years of staffing increases, have been forced to make cutbacks(削减).
     The police chief in Camden, N.J., J. Scott Thomson, whose force of 400 was cut by nearly half
last year because of financing issues, said that having fewer officers on the street "makes it that much
more difficult to create an environment in which criminals do not feel as encouraged to attack anothe
r person, let alone a law enforcement officer."
     "Every stop can be potentially fatal, so we are trying to make sure the officers are ready and
prepared to face deadly force every single day they go out." Ms. Klimt said.

     BEIJING --Seven prestigious universities in China announced Sunday that they would begin using the
same independent exam -- besides the national one -- to test students hoping to gain entrance to them in
2011.
     The seven are Peking University, Beihang University, Beijing Normal University, Nankai University,
Fudan University, Xiamen University and Hong Kong University.
Students who want to gain entrance to any of the seven universities will only have to sit one independent
exam, according to the joint announcement.
    "This will help lighten tile students' load, otherwise they must take several exams for different universities," said the announcement.
    Passing the exam could result in more than one interview chance, giving the students more opportunities to choose their favorite universities.
    China's college entrance exam system is undergoing reform as universities aim to select students based
on independent criteria rather than just using the results of the national exam.
     In 2003, Peking University and another 21 universities were allowed to pilot (试用) the reform by
using their own criteria to independently select five percent of their students.
     Now nearly 80 universities across the country have the right to select talented students based on their
own exams.
     Education experts regard universities selecting students according to independent examinations as
conducive (有助的) to better understanding where the students' talents lie.
    Although this may be the case, it has also created problems as students may sit many different exams
as they often apply for a number of universities.
     To relieve students from such pressures, the national education outline (2010--2020) released in July
this year encourages high-level universities to group together to use the same exams.

1. If students want to be admitted to the seven prestigious universities , they can ______.
A. only pass the interview.B. only take the national exam.
C. only take the independent exam.
D. either take the national exam or the take the independent exam.

2. What's the purpose of students sitting one independent exam to gain entrance to the seven universities ?
A. It can reduce students' load to take several exams.
B. The universities will have the same standard to test students.
C. There will be less trouble marking students' test papers.
D. It can avoid fierce competition among these universities.

3. If students pass the independent exam , they will ______.
A. take the national exam.B. have one or more interview chances.
C. be admitted to one of the universities.
D. he trained to be adapted to universities life and studies.

     TOKYO--- A child-like robot that combines the roles of nurse, companion and security guard is to go on the market to help the growing ranks of elderly Japanese with no one to look after them.
     The "Wakamaru" robot can walk around a house 24 hours a day, warning family, hospitals and security firms if it perceives (觉察) a problem. It will, for example, call relatives if the owner fails to get out of the
bath.
     Cameras implanted in the "eye-brows" of the robot enable it to "see" as it walks around an apartment. The images can be sent to the latest cellphones, which display the pictures.
     Wakamaru, which speaks with either the voice of a boy or a girl, is also designed to provide
companionship, greeting its "papa" when he comes home.
     It is the first household robot able to hold simple conversations, based on a vocabulary of around
10,000 words. It cannot only speak but can understand answers and react accordingly.
     Wakamaru will inform a security firm if there is a loud bang or if an unknown person enters the house
while the owner is out or asleep. It can recognize up to 10 faces.
     But like most robots it cannot climb stairs.
     Mitsubishi Heavy Industry, which developed Wakamaru, adapted Wakamaru from robots it made.
     The idea to use the technology in the home came from a company employee.
     The technology has gained nation-wide publicity in Japan among increasing concern over how to look
after the ever-growing number of old people. The life of Japanese women has shot up to almost 85 years,
the highest in the world.
     At the same time, extended families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents, whom they rarely see because of their long hours at office.
1. Which of the following is true about Wakamaru?
A. It is used in a security firm.
B. It cannot speak but can understand answers.
C. It can go up and down the stairs easily.

     WASHINGTON: An analysis of global temperatures by independent statisticians shows the Earth is
still warming and not cooling as some global warming skeptics are claiming.
     The analysis was conducted at the request of The Associated Press to investigate the legitimacy of
talk of a cooling trend that has been spreading on the Internet, fueled by some news reports, a new book
and temperatures that have been cooler in a few recent years.
     In short, it is not true, according to the statisticians who contributed to the analysis.
     The statisticians, reviewing two sets of temperature data, found no trend of falling temperatures over
time.US government data show the decade that ends in December will be the warmest in 130 years of
record-keeping, and 2005 was the hottest year recorded.
     The case that the Earth might be cooling partly stems from recent weather. Last year was cooler than
previous years. It has been a while since the superhot years of 1998 and 2005. So is this a longer climate
trend or just weather's normal ups and downs?
     In a blind test, the AP gave temperature data to four independent statisticians and asked them to look
for trends, without telling them what the numbers represented. The experts found no true temperature
declines over time.
     "If you look at the data and sort of cherry-pick a microtrend within a bigger trend, that technique is
particularly suspect," said John Grego, a professor of statistics at the University of South Carolina.
     Yet the idea that things are cooling has been repeated in opinion columns, a BBC news story posted
on the Drudge Report and in a new book by the authors of the best-seller Freakonomics. Last week, a
poll by the Pew Research Center found that only 57 percent of Americans now believe there is strong
scientific evidence for global warming, down from 77 percent in 2006.          

1. The first paragraph serves as a (n) _______.

A. explanation      
B. introduction        
C. comment        
D. background

2. According to the passage ,the hottest year in 130 years of record-keeping is _____ .

A. 1998            
B. 2005              
C. 2006            
D. 2010

3. How many factors lead to the idea that the earth is cooling?

A. 2              
B. 3                    
C. 4                
D .5

4. We can learn from the passage that _____.

A. five independent statisticians were given temperature data to look for trends
B. more and more Americans now believe there is strong scientific evidence for global warming
C. The analysis of global temperatures was required by the independent statisticians
D. The earth is not becoming cooler as some people are claiming on the internet

     China Daily Oct.11,2008-The Ministry of Health has called for more awareness from the public on
the mental health of the young,  as part of efforts to mark World Mental Health Day which fell on Friday.

inability to handle interpersonal  relations well,  unstable emotions and pressures from an overload of
studies.A number of experts have also said the onechild policy is another reason leading to poor mental
health in the young.Children are said to be too "spoiled" and "selfish" in a onechild family.

     WASHINGTON-Thanks to strong economic growth and a growing middle class, China has surpassed
India for the first time this decade to become the country that sends the most students to the United States,
according to the annual report the Institute of International Education (IIE) released (发布) on Monday.
     The number of Chinese students in the US has increased by 30 percent during the 2009-2010 academic
year to about 128,000, or 18.3 percent of the total international student population in the country, the report
said.
     "The Chinese economy is booming. The growing middle class are able to send their children abroad for
higher education as many families have only one child and they use all their resources on that child." said
Peggy Blumenthal, executive vice-president of IIE.
     Another reason is that many Chinese parents are attracted by the US higher education system. "American
undergraduate education is really appealing Chinese parents who are thinking about what is needed for China
in the future and how their son or daughter can be employable," Blumenthal said.
     Chinese overseas study agencies expect more Chinese students to go to the US next year, partly due to
the weakened US dollar and more flexible visa policies.
     The study and living costs for an undergraduate Chinese student in the US every year are roughly about
250,000 yuan ($37,000), and the depreciation of the US dollar may save about 10 percent of the cost, said
Liu Qingsheng, a senior manager with Shinyway International, a Beijing-based overseas study consulting
company.
     A more flexible visa policy, which the US started to adopt in 2008, is another major attraction, he said.
1. According to the passage, we know during the 2009-2010 academic year, _____.
A. the number of India students in the US has increased
B. as many as 128,000 international students study in the US

D. more than 18.3 percent of Chinese students study abroad
2. More Chinese students go to US universities because of the following reasons except _____.
A. a more flexible visa policy
B. the US higher education system
C. a proving middle class in China

     LOS ANGELES-Old people who keep walking a relatively long distance may be less likely to suffer
from cognitive(认知的) decline, a new study suggests.
     "By walking regularly, and maintaining a little bit of moderate physical activity, you can reduce your
likelihood of developing Alzheimer's disease and spare brain tissue," Kirk I．Erickson, the study's lead
author, said.Erickson and his colleagues from the University of Pittsburgh began to establish a link between walking and memory in 1989.
     According to the report on their study published online Wednesday in Neurology, an official journal of
the American Academy of Neurology, researchers tracked the physical activity and cognitive patterns of
nearly 300 adults.
     At the very beginning, all participants, on average 78 years old and about two－thirds being women,
were in good cognitive health. The researchers charted how many blocks each person walked in one
week. Nine years later, the participants were given a MRI scan to measure their brain size. All of them
were deemed to be "cognitively normal."
     But after four more years, test showed a little more than one third of the participants had developed a
mild cognitive impairment or dementia.
     By correlating cognitive health, brain scans and walking patterns, the research team found that being
more physically active appeared to lower the risk of developing cognitive impairment.
     As to how much walking would help prevent cognitive decline, the researchers suggested that walking
about six miles, or 9.6 km, per week appears to protect the brain against shrinking in old age.
     The researchers said the relationship between walking and gray matter volume appears to apply only to people who regularly walk relatively long distances.
     The more someone walks, the more gray matter tissue the person will have a decade or more down the road in regions of the brain, namely the hippocampus, the inferior frontal gyrus and the supplementary
motor area, that are central to cognition.
     And among the more physically active participants who had retained more gray matter a decade out,
the chances of developing cognitive impairment were cut in half, the study said. 
1. When did the old people tested in the research begin to show difference in cognitive decline?
A. When they were 78 years old.
B. When they were 87 years old.
C. Between the year 1989 and 1998.
D. Between the year 1998 and 2002.
2. What do we know about the gray matter?
A. The quantity of it has a decisive influence on the cognitive ability.
B. It's something in the muscle that develops from physical activity.
C. It's a brain disease that will damage the cognitive ability.
D. It's some brain matter that can cure brain diseases.
3. Which of the following is closest in meaning to the underlined word "shrinking" in Para.9?
A. worrying.  
B. weakening.
C. widening.
D. wandering.
4. What is TRUE about the research?
A. Men and women differ in the decline of cognition.
B. The research subjects were required to walk blocks per week.
C. The findings suggest the more walking, the better health.
D. There were about 200 women involved in the research.
