B
What happens inside the skull of a soccer player when repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.

All parents know that one of their most important tasks is to prepare their children for an independent life, but any parent can tell you that it’s hard to let go of your children. That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking. Years of experience means that parents often do know best, but on the other hand the young, being less bound by tradition, are often more creative, more able to find new solutions to old problems. Revolutions are led by the young.
Good teachers make the growth of critical thinking (批判性思维) easier in their students, only to find that this lead to a questioning of the teachers’ basic beliefs. Schools encourage parents to become involved, but are often embarrassed when parents have doubts about some of the educational methods being used. Governments encourage unimportant groups to empower themselves in order to participate fully in the development process. And they are often surprised when the new leaders of these groups turn around and attack the policies or decisions of that same government. However, the rebellious (叛逆的) young and the newly unimportant groups are important in social development. They are not necessarily representatives of those they want to represent in their demands, but their voices must be heard.
Good parents know that just forbidding (禁止) particular behaviors does not prevent their children from finding ways to engage in these forbidden activities. Indeed, sometimes the forbidden fruit is more inviting, just because it is not accepted by authority. Parents must work with their children to educate them on the facts, know as much as possible about the lives of their children, provide a good example, encourage more wholesome activities but also support their children when they don’t follow what is expected of them. But the most important point is that they also need to learn how to let go.
小题1:By saying “Revolutions are led by the young.”, the author indicates that young people are more _______.| A．conventional | B．realistic | C．creative | D．heartbreaking |
小题2:From the second Paragraph we know ________.| A．teachers’ basic beliefs should be questioned by students | | B．schools encourage parents to question their education methods | | C．government is satisfied with the new leaders’ attack on the policies | | D．the voice of the rebellious young should be heard by the government |
小题3:In order to educate children well, parents should _______.| A．forbid particular behaviors in their daily life | | B．know them well and set a good example to them | | C．educate them with facts and expect much of them | | D．know as much as possible about their children |
小题4:From the passage we can learn that the author prefers _______.| A．free parenting | B．traditional parenting | | C．critical parenting | D．smart parenting |
小题5:What is the best title of the passage?| A．Letting Go – for Children’s Independent Life | | B．Parents’ Task – in Children’s Development | | C．Way of Growth – for the Young Groups | | D．Teaching Methods – for Teachers and Schools |

Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.
A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.
One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.
The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).
小题1:What’s the main idea of the first paragraph?| A．Explaining why there is a lack of rain at times. | | B．Introducing several different patterns of rainfall. | | C．Telling us how to avoid problems caused by rain. | | D．Giving the idea that there are ways to manage rain water. |
小题2:According to the second paragraph, “Rain Gardens" are likely to _____.| A．harm the environment in the short run | | B．become popular over the next few years | | C．be turned down by most new developments | | D．be too expensive for common people to accept |
小题3:We can learn from the third paragraph that _____.| A．floods are often the results of small rains | | B．a heavy rain is less difficult for plants to absorb | | C．the rain garden helps send rainwater back into the air | | D．larger amounts of rainwater flow straight off in city environments |
小题4:According to the last paragraph, what does the rain garden help to clean?| A．The plants | B．The ground. | C．The water. | D．The street. |

Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.
小题1:Paying students who show improvement in tests __________.| A．has been done in most American schools | | B．is becoming a growing practice in the USA | | C．is not very popular with teachers | | D．only aims at high scores at school |
小题2:According to the text, Robert Schaefer _____________.| A．is a very excellent teacher | | B．thinks highly of paying students | | C．thinks students will show improvement in study in the future | | D．thinks people should make a careful plan for the paying program |
小题3:From the last paragraph we can see __________.| A．EBCWRU has got great success in its paying program | | B．not all the students in EUCWRU have made progress in all subjects | | C．only students who study math can get paid | | D．EBCWRU will go on with the paying program |
小题4:The text is mainly written to _____________.| A．persuade teachers to give students more prizes | | B．tell people how to become an excellent student | | C．introduce something about American paying students program | | D．explain the advantages of American paying students program |

BEIJING — China’s education authority will tighten the widely criticized policy of “extra credits” for the national college entrance examination to ensure a fairer chance for all exam-takers.
Under the policy, high school students who win awards in national Olympic competitions could get ‘‘extra credits’ up to 20 points for the national college entrance exam. Students with talent in sports and students who are from ethnic groups can also benefit from this policy. The extra credits have increased these students’ chances of being admitted by famous universities. Some parents were found to have helped their children fabricate(伪造)award experiences or falsify qualifications to get extra credits.
“It has harmed education equality，” the ministry said.
Xiong Bingqi, vice-chief of the 21st Century Education Research Institute, said the policy is designed to help students who have special talents but may be weak in academic performance to have a chance to receive higher education. uIt will still be needed but it is time to make the rules fairer," he said.
The ministry said it will reduce the range of competitions whose winners can get extra credits, and limit the winners, privileges(优先权).
The new policy will apply to students who begin high school in 2011, it said.
Chen Lei, a mother of a 10-year-old girl, said she welcomed the ministry"s policy adjustment as she does not want her daughter to become an Olympic competition geek.
But not all the Chinese parents welcomed the new policy. “It is like a thunderbolt for me. My - 13-year-old son has spent so much time studying Olympic math，and participated in so many technological competitions during vacations. It is useless now,” said Dong Wen, a 43-year-old mother.
A student said, “Many students have changed the current study plan, and they can abandon the competition. I will be interested in learning the courses which can improve my abilities.”
Yuan Guiren, minister of education, told China Daily that the reform is an attempt to consider the overall quality of an applicant. “But the country will not stop the national college entrance examination as it is still the most objective way to evaluate talent in China，” lie said.
小题1:It can be inferred from the passage that_____.| A．high school students with talent in sports are weak in academic performance | | B．students who win awards in Olympic competitions can’t get extra credits in 2011 | | C．the number of competitions whose winners can get extra credits will be smaller | | D．the extra credits have reduced students" chances of being admitted by famous colleges |
小题2:What does the underlined word “geek” probably mean?| A．a winner | B．a smart learner | C．a competitor | D．a dull student |
小题3:Which person in the passage was strongly against the new policy?| A．Xiong Bingqi | B．Chen Lei | C．Dong Wen | D．Yuan Guiren |

In order to know a foreign language thoroughly(完全地), four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly with confidence and without hesitation(犹豫). Thirdly, we must be able to write it. We must be able to make sentences that are correct in grammar.
There is no short way to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use learning by heart long lists of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must “Learn through use”. Practice is important. We must practice speaking and writing the language whenever we can.
小题1:The most important things to learn a foreign language are_______.| A．understanding and speaking | | B．hearing, speaking, reading and writing | | C．writing and understanding | | D．memorizing and listening |
小题2:One can never learn a foreign language well only by_______.| A．much practice | B．studying the dictionary | | C．learning through use | D．using the language |
小题3:“Learn through use” means_______.| A．we use a language in order to learn it | | B．we learn a foreign language in order to use it | | C．we can learn a language well while we are using it | | D．both B and C |
