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 (腦震蕩) 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 (外傷的) 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.
小題1:The passage is most probably a ________.
A.news report B.research report
C.story for soccer players D.text for doctors
小題2: In which way can researchers find the structural changes in the brain?
A.Computerized test B.Questionnaire
C.Scanning D.M.R.I. technique
小題3: From the passage we can conclude that frequent heading may have ________.
A.significant effect on brain B.little effect on one’s brain
C.nothing to do with the brain injury D.one’s memory improved
小題4:What is likely to be the cause of memory loss?
A.Playing soccer frequently B.Tests of their memory
C.White matter loss D.Information processing
小題5:The underlined word “fumbling” is closest in meaning to ________?

A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
小題1:According to the text, Driver Alert ______.
A.a(chǎn)ims to reduce tiredness-related accidents
B.has gone through testing at laboratories
C.a(chǎn)ims to prevent drivers from sleeping
D.has been on sale for 12 months
小題2:How should a driver respond to the sounds from Driver Alert?
A.By sounding a warning.B.By touching the wristband.
C.By checking the driving time.D.By pressing the steering wheel.
小題3:We can learn form the text that the driver needs to stop for a break when his response time is ______.
A.a(chǎn)bout 400 millisecondsB.below 500 milliseconds
C.over 500 millisecondsD.a(chǎn)bout 4 minutes
小題4:When the driver gets sleepy while driving, Driver Alert ______.
A.moves more regularlyB.stops working properly
C.opens the window for the driverD.sounds more frequently and loudly

As they migrate, butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may use some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.
To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate(補(bǔ)償, 彌補(bǔ)). Many migrating birds do the same thing.
The study also found that butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help farmers decide when to spray their crops.
小題1:What's the main idea of the text?
A.Insects migrate with the seasons.
B.The wind helps insects greatly in migrating.
C.Windsurfing insects have real direction.
D.Scientists have trouble in observing insects.
小題2:Scientists originally thought that _____.
A.insects always waited for their favorable winds
B.insects chose the winds they wanted to ride
C.insects were just blown about by the wind
D.insects positioned themselves in the winds
小題3:It is not easy to study the migrating behavior of the insects because ______.
A.the little creatures can fly very fast
B.their flight is long and high above ground
C.the wind's direction is hard to forecast
D.they have no regular migrating courses
小題4:According to the passage, the findings can ____
A.increase insects in number
B.instruct farmers when to spray their crops
C.prevent climate warming
D.help protect insects

根據(jù)短文內(nèi)容,從下框的A—F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng)。選項(xiàng)中有一項(xiàng)為多余項(xiàng)(E涂AB,F涂AC)
A Avoid asking your child too many questions
B Tell your child stories about your growing up
C Don’t judge or criticize your child
D Listen to your kids with respect
E Provide pressure-free conversation opportunities
F Ask children gently what they think
   If your child has gone from a continuous chatterbox to making conversations that consist mostly of yes and no, it’s time to consider these tips on how to talk to kids, so you’ll know what’s going on in your child’s world.
小題1:  
The quickest way to get kids to shut up and, as a result, shut you out of their lives is to continuously press them about things. A more effective way is to sit back and patiently wait for them to open up in a low-stress family and then be prepared to listen.
小題2:  
Parents can sometimes make kids at a young age decide it is best not to talk about something when they are criticized. If you really want to know what’s on your child’s mind, then avoid passing judgment and focus instead on why something seems important to your child.
小題3:
If you want to raise a creative and independent thinker, stop telling your child what he ought to feel or think. You can gently encourage additional conversations by simply asking why he feels the way he does or what he would do in a certain situation.
小題4:  
You may think you’re just asking questions out of curiosity when communicating with your child, but an endless stream of questions about what they did, whether everyone got along, if they went to the bathroom, ect., are enough to make anyone shut up! Practice patience and let your kids open up on their terms.
小題5:
Kids can relate to you and other adults when you tell your stories happening when you were their age. Talking to kids by telling them about things like something embarrassing that happened or the first crush(迷戀) you had helps them to connect with you and understand that you might actually know what they are going through!

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(猶豫). 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.
小題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
小題2:One can never learn a foreign language well only by_______.
A.much practice B.studying the dictionary
C.learning through useD.using the language
小題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

(D)
You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.
小題1:You can see the book because_______.
A.your eyes are close to it B.it reflects some of the sunlight
C.it has light of its ownD.your eyesight can get to it
小題2:The underlined word “l(fā)uminous” means_______.
A.visibleB.a(chǎn)ll colorsC.giving off lightD.sunlight
小題3:________ have light of their own.

Back those photos up
The images were striking.Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions.
If that doesn't move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos.
Here is a brochure (手冊(cè)) on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad.
Scanning
The first step for those old photos is to scan them and save them to a digital format (格式).Most,printers come with scanners these days, so that's an easy but extremely time-consuming step.
Storing the photos
With your scans in place, import the photos into your computer, and back them up.
You could make multiple copies of the disks and spread them to loved ones.Or you could choose external (外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer.
Online backup
If you need lots of space, look at a pure online backup service, Caronite.
Caronite backs up 300 million files daily.Once you sign up, it starts to pick up everything you have on your hard drive.But photo collection on your computer's main hard drive charges for $ 59 a year.
Cloud Storage
For folks who don't need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft's SkyDrive let you store files online by yourself, share and instantly access them.All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive.But if you want more, you need to pay.
Bottom Line
The hard drive or flash drive is the cheapest and easiest.But drives can fail.Online services are more expensive, but more secure.With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are.
小題1:What can we know from the passage?
A.Scanning photos takes little time but costs a lot.
B.The hard drive or flash drive is the cheapest and safest.
C.Google Drive offers unlimited free photo storage on line.
D.Caronite charges for backing up photos from hard drive.
小題2:Which of the following allows storing files automatically?
A.Caronite.B.Dropbox.C.SkyDrive.D.Flash drive.
小題3:The main purpose of the passage is to ______.
A.tell real stories about storage services
B.introduce some of the storage services
C.describe the functions of storage services
D.a(chǎn)rgue about the advantage of storage services

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.
Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.
“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.
The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.
“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近親交配) problems ... and at the end these species may disappear,” he added.
Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.
The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.
Other consequences could include the spread of invasive species and infectious diseases, it said.
The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(紅樹林), inland waters, forests, savannahs(非洲大草原) and grasslands.
The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.
The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.
It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.
小題1:What does the author tell us in Paragraph 2?
A.The theme of global climate negotiations in Durban.
B.The subject of research done by Eduardo Rojas.
C.Causes of damage done to ecosystems.
D.Harmful effects of damage done to ecosystems.
小題2:Why are animals living in mountains, islands and coastal areas most affected?
A.They are frequently attacked by invasive species and infectious diseases.
B.They have difficulty finding enough food for survival.
C.They can hardly find mates to produce their young.
D.They have little chance of moving to other places.
小題3:To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT ______.
A.restoring damaged ecosystems
B.limiting world population growth
C.creating movement channels for animals
D.urging governments and local communities to take action
小題4:What does the underlined word “mitigate” in the last paragraph mean?
A.increase or further improve something.
B.Make full use of something.
C.Make something become less serious.
D.Move from one place to another.
小題5:What would serve as the best title for the passage?
A.Animals at risk due to climate change.
B.Global warming and its consequences.
C.Climate change and ecotourism.
D.Solutions to animal distinction.

Earlier this year, the Environmental Protection Agency proposed a stricter nationwide health standard for smog-causing pollutants that would bring substantial benefits to millions of Americans. With a final rule expected by the end of this month, some opponents, mainly from industrial and oil-producing states, are pushing back. They say investments required to produce cleaner air are too expensive and not scientifically justified.
Lisa Jackson, the E.P.A. administrator, needs to stick to her guns. This is only the first of several political tests to come this fall, as she also seeks to tighten rules governing individual pollutants like mercury and global warming gases like carbon dioxide.
The health standard she is proposing covers ground-level ozone, commonly known as smog, which is formed when sunlight mixes with pollutants from factories, refineries, power plants and automobiles. Ozone is a major health threat, contributing to heart disease and various respiratory (呼吸道的) problems.
Ms. Jackson’s proposal—to reduce the permitted level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billion—is sensible, no matter what industry’s defenders may claim. It had been recommended by the agency’s independent scientific panel but rejected by the Bush administration, which proposed a weaker standard.
Industry will have to make investments in cleaner power plants, and new technologies may be required. As it is, about half the counties that monitor ozone levels are not yet in compliance with current standards, let alone the proposed standard.
Fears about burdening industry raised by critics like George Voinovich, a Republican of Ohio, and Mary Landrieu, a Democrat of Louisiana, cannot be dismissed out of hand, especially in the middle of a recession (蕭條). But the health benefits, E.P.A. says, far outweigh the costs, and the time frame for compliance (服從) is generous.
小題1:Why are some people strongly against a stricter limitation of smog-caused pollutants?
A.Because they have to live a poorer life.
B.Because they think they have to spend more money.
C.Because they hold different political view.
D.Because they want to make more money.
小題2: What does Ms Jackson propose to do?
A.To reduce the permitted smog level as much as possible.
B.To raise the permitted smog level as much as possible.
C.To keep the permitted smog level from 60 to 70 to 75 parts per billion.
D.To lower the permitted smog level from 75 to 60 to 70 parts per billion.
小題3:What is the attitude of the author to the smog-controlling issue?
A.Objective.B.Subjective.C.Critical.D.Unknown.
小題4:Which of the following can serve as the best title of the whole passage?
A.Cleaner power plant on the way.
B.Say no to smog pollutants.
C.Lower smog pollutant, better our life.
D.Debate on smog pollutants.
