Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week,she held her breath as the air became a charcoal grey haze(炭灰色的陰霾).The 39­year­old businesswoman has lived in Beijing for a decade,and this past month,she said,brought the worst air pollution she has ever seen.It gave her husband a cough and left her seven­year­old daughter housebound(足不出戶).“My husband as well as I is working here,so we have no choice,” she said.“But if we had a choice,we'd like to escape from Beijing.”
The extended heavy pollution over the last month,which caused punishment in return for a day last week-called the “airpocalypse” by internet users- has largely changed the way that Chinese think about the country's air.On one day,pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO).Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January,Beijing's air was worse than that of an airport smoking area.
The smog's(煙霧) most threatening aspect is its high concentration(濃度) of PM 2.5 - particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream,causing breathing infections,lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year,65% of them in Asia.

German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper,published this March in Psychology and Aging,examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96.The surveys were conducted every year from 1993 to 2003.
Survey respondents (受訪者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10,among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction,while middle­aged adults (age 40 to 64) more accurately predicted how they would feel in the future.Adults of 65 and older,however,were far more likely to underestimate their future life satisfaction.Not only did they feel more satisfied than they thought they would,the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,”wrote Frieder R.Lang,a professor at the University of Erlangen­Nuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (預防措施),”the authors wrote.
Surprisingly,compared with those in poor health or who had low incomes,respondents who enjoyed good health or income were associated with expecting a greater decline.Also,the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions.Illness,medical treatment and personal loss could also have driven health outcomes.
However,the researchers said a pattern was clear.“We found that from early to late adulthood,individuals adapt their expectations of future life satisfaction from optimistic,to accurate,to pessimistic,”the authors concluded.
小題1:According to the study,who made the most accurate prediction of their future life satisfaction?
A.Optimistic adults.
B.Middle­aged adults.
C.Adults in poor health.
D.Adults of lower income.
小題2:Pessimism may be positive in some way because it causes people________.
A.to fully enjoy their present life
B.to estimate their contribution accurately
C.to take measures against potential risks
D.to value health more highly than wealth
小題3:How do people of higher income see their future?
A.They will earn less money.
B.They will become pessimistic.
C.They will suffer mental illness.
D.They will have less time to enjoy life.
小題4:What is the clear conclusion of the study?
A.Pessimism guarantees chances of survival.
B.Good financial condition leads to good health.
C.Medical treatment determines health outcomes.
D.Expectations of future life satisfaction decline with age.

(2013·高考福建卷,B)Your glasses may someday replace your smartphone,and some New Yorkers are ready for the switch.Some in the city can’t wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
“ I’d use it if I were hanging out with friends at 3 a.m.and going to the bar and wanted to see what was open,”said Walter Choo,40,of Fort Greene.
The smartphone­like glasses will likely come out this year and cost between $250 and $600,the Times said,possibly including a variation of augmented(增強的) reality,a technology already available on smartphones and tablets (平板電腦) that overlays information onto the screen about one’s surroundings.So,for example,if you were walking down a street,indicators would pop_up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
“As far as a mainstream consumer product,this just isn’t something anybody needs,”said Sam Biddle,who writes for Gizmodo.com.“ We’re accustomed to having one thing in our pocket to do all these things,”he added,“and the average consumer isn’t gonna be able to afford another device (裝置) that’s hundreds and hundreds of dollars.”
9to5Google publisher Seth Weintraub,who has been reporting on the smartphone­like glasses since late last year,said he is confident that this type of wearable device will eventually be as common as smartphones.
“It’s just like smartphones 10 years ago,”Weintraub said.“A few people started getting emails on their phones,and people thought that was crazy.Same kind of thing.We see people bending their heads to look at their smartphones,and it’s unnatural,”he said.“ There’s gonna be improvements to that,and this a step there.”
小題1:One of the possible functions of the smartphone­like glasses is to ________.
A.program the opening hours of a bar
B.supply you with a picture of the future
C.provide information about your surroundings
D.update the maps and GPS in your smartphones
小題2:The underlined phrase“pop up”in the third paragraph probably means“ ________”.
A.develop rapidly
B.get round quickly
C.appear immediately
D.go over automatically
小題3:According to Sam Biddle,the smartphone­like glasses are ________.
A.necessary for teenagers
B.attractive to New Yorkers
C.available to people worldwide
D.expensive for average consumers
小題4:We can learn from the last two paragraphs that the smartphone­like glasses ________.
A.may have a potential market
B.are as common as smartphones
C.are popular among young adults
D.will be improved by a new technology

(2013·宜春五校聯(lián)考)Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station.
Once inside,the cow is rewarded with food.As the cow eats,a robotic arm cleans and connects the animal to the milking machine.A few minutes later,milking is complete.The gate is opened,the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still,she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot costs 175,000 dollars.The second costs 150,000 dollars.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day.
小題1:From the first paragraph,we can infer ________.
A.the robotic system is designed to reduce labor
B.cows can be raised by robots in the future
C.robots direct cows into milking stations
D.cows are kept clean by robots on some farms
小題2:Besides milking cows,the robotic system also can ________.
A.adjust the temperature of milking stations
B.judge the quality of fresh milk
C.improve the appetite of cows
D.keep fresh milk for two weeks
小題3:Why is the robotic system not popular now?
A.Because young people have no interest in it.
B.Because it is difficult to learn how to use it.
C.Because people can't afford to buy it.
D.Because it usually causes the waste of milk.
小題4:According to Doug,what is the wage of an employee per year?
A.$150,000~$175,000.
B.over $75,000.
C.$150,000~$30,000.
D.$30,000~$35,000.

With 10, 600 bicycles in circulation,Paris city officials are hoping the program will provide people with more environmentally friendly transportation.

It seems both Parisians and tourists are taking advantage of the program.Since its launch a little over two weeks ago,Vélib has already seen almost half a million rentals.And,with the addition of 10,000 more bikes and 700 more stations in the next 12 months,city officials expect at least 200,000 regular users by year end.
Parisian Olivier Bioret has already gone for a spin on one of Vélib’s vehicles and plans to make use of them more often.
“It’s a real pleasure—when,like me,you don’t have space enough in your flat to have your
own bike—to be able to discover.to cross Paris and not have to take the subway,”he said.
As a socialist and longtime green activist,Mayor Bertrand Delanoe regards Vélib as just a part of his plan to reduce car traffic and,thus,lower pollution by 2020.
Apart from its environmental benefits,Vélib is also being praised as a way of collecting money for the city,for all the money from rentals goes to the city government.
Paris is not alone in its attempt to profit from the power of the bicycles.
Across the globe,cities such as Barcelona,which stated its bike-share program in March with 1,500 vehicles and 100 stations,and New York,which launched a five-day trial program last month,are using bicycles as a way to cut back on both traffic and pollution.
However,it remains to be seen whether people’s acceptance of these programs is simply a
passing fashion or whether this movement has the power to take root and transform the face of public transportation around the world.
小題1:The real purpose of Vélib is________.
A.to help people save money and space
B.to make some money for the city government
C.to provide convenience to both Parisians and tourists
D.to reduce traffic and pollution in the city
小題2:Which of the following is TRUE according to the passage?
A.There will be 700 stations in one year’s time.
B.There will be over 20, 000 bikes in use in a year.
C.In the first two weeks there were nearly a million rentals.
D.There will be 200, 000 regular rentals each day by year end.
小題3:We can know from the passage that_________.
A.other cities also have such programs
B.Parisians can use the bicycles free of charge
C.Paris sets an example to many other cities
D.Paris is the first city to start such a program
小題4:As to the future of the program,the author is_________.

Science Daily—Kids may roll their eyes when their mothers asks them about their school day, but answering her may actually help them learn. New research from Vanderbilt University reveals that children learn the solution to a problem best when they explain it to their mom.
“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”
Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.
“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
小題1:According to the passage, a mom had better ________.
A.give a kid some help when he is explaining his problem
B.just listen while a kid is explaining his problem
C.work together with a kid toward the solution to a problem
D.leave a kid alone when he meets a problem at school
小題2: If she wants to help a child with his schoolwork, a mom ________.
A.should know the answer to a problem first
B.should pay attention to the child’s feedback.
C.may not know the answer herself
D.should not interrupt the child
小題3:Who will be the least help to a kid when he is explaining, according to Rittle-Johnson?
A.The kid’s mom.
B.The kid’s grandmother.
C.A peer.
D.A relative the kid doesn’t know.
小題4:Which of the following best gives the main idea of the passage?
A.Children learn better when their mom is hearing their explaining.
B.Children learn better if they find the solution to a problem themselves.
C.Parents should not provide any assistance to their children’s schoolwork.
D.A mom should listen more to their children when they have problems at school.

Fear is an emotion like others such as happiness, anger, hurt, sadness. We need emotions to process information we receive and decide how to respond. Being afraid of fast cars, for example, is something that might protect us from harm. Being afraid of the consequence of a choice may prevent us getting into trouble.
Fears in young children commonly center on certain animals like snakes or big dogs. Fears are caused often because of experiences or ideas expressed by others, and at times, the media. Many normal fears during the early years, like men with beards, or large dogs, disappear with age. Those relating to personal failure and ridicule (嘲笑) remain through adulthood and may need special help to overcome.
Children’s fears are often trivial, but that doesn’t mean they should be ignored. They need to be recognized and accepted as real for that child. Only when we help children understand their fears can they grow normally in their ability to deal with them.
Research shows that as a child grows up, the center of his fears changes a lot. Things like divorce, a teacher who “shouted at me”, people with guns, bullies, big boys, or “making fun of me” top the list of childhood fears.
We can not always prevent these experiences from happening, but it’s essential that children be allowed to freely express their emotions without judgment. Sympathy and a caring listener will help ease the pain of these fears. Read books and stories to your child about children who have experienced similar fears. This helps children talk about their fears and find ways to cope. With all emotions, fears become less of a problem for children as they gain self-confidence and they find that fear is normal and can be dealt with.
小題1:According to Paragraph 2, we can know that fears in young children_______.      .
A.only center on frightening animalsB.are not born but learned
C.can make sure of their safetyD.need special help to deal with
小題2:The underlined word “trivial” in the third paragraph probably means “_______”.
A.smallB.seriousC.harmfulD.common
小題3:In dealing with children’s fears, the final goal of the parents is to _______.
A.stop unpleasant experiences happening to children
B.let children know about the nature of fear
C.create an environment where there is nothing to fear
D.develop children’s ability to treat their fear on their own
小題4:From the passage we can learn that ________ .
A.some childhood fears may have a lasting influence
B.children should avoid the media to reduce their fear
C.fears can be judged according to the environment
D.children with similar fears can communicate easily

When did you last go outside for sports? Some students might need a while to remember. But for students in Yangzhou University it is easy to remember as they need to run in the morning at least three times a week during their two terms. The university even uses fingerprint punch-in clocks(指紋簽到機) to manage students’ records. However, some students still try to skip(不參加) morning running. To them, sports are just not important enough.
Now colleges are seeing a change in the student lifestyle from outdoor enthusiasts to indoor couch potatoes and Internet addicts. The Internet and various on-campus services, from food delivery to laundry, are leading to a student culture of staying in dormitories. A student can have every need met without leaving the dormitory.
In the past two years Zhang Yi, 20, a junior majoring in law at Yangzhou University, has never been outside for sports except during physical education class. “I don’t think there is anything wrong with sleeping late in the morning and wanting to stay in the dormitory in my spare time. I have more fun doing things on my computer than playing on the sports ground in wet clothes.” said Zhang.
“With social networking sites, online games and micro-blogging added to already tight schedules, sports are often the last thing to be considered.” said Cheng Jie, 21, a senior majoring in civil engineering at the Southeast University in Nanjing.
But Jin Yinghua, a professor at Beijing Sports University, said that sports are not only for keeping fit, but also an irreplaceable(不能替代的) “education” for students. Sports are not only a way for students to train their body, but also an important way to learn responsibility, teamwork and devotion.
小題1:The first paragraph mainly tells us ________.
A.the fingerprint punch-in clocks are widely used
B.some college students have poor memories
C.students cannot skip morning running any more
D.the problem of students skipping sports is serious
小題2:According to Cheng Jie, college students ________.
A.love sports more than anything else
B.prefer Internet games to sports
C.enjoy sleeping late in the morning
D.are too busy with study to do any sports
小題3:Professor Jin thinks that _______________.
A.sports play an important role in students’ over-round development
B.the most important goal for students to do sports is to keep healthy
C.universities should take tough measures in student management
D.the spirit of responsibility can be developed in more than one way
小題4:The best title of the passage would be________.
A.Morning running at collegesB.A new college life
C.Sports losing attractionD.P.E. class at colleges
