These days it’s cheaper to throw that broken DVD player, cell-phone or TV out and buy a new one. This “ replace-rather-than-repair” mentality is polluting the planet with electronic waste. According to the UN Environment Program, we are throwing away an estimated 50 million metric tonnes of electronics waste    (e-waste) per year. But this is not ordinary garbage. Our electronics leak harmful heavy metals — such as mercury and arsenic — along with equally poisonous chemicals that end up in our soil and eventually our water.
You’ve probably participated in a community recycling event and left feeling good about shipping off that old computer to be recycled. Chances are it was shipped overseas where it’s polluting someone else’community.
Guiyu city in Southeastern China has become known as the e-waste city where low-paid workers use whatever means available to remove electronics in hopes of recovering the copper, microchips, aluminum, gold and silver and plastic that can be resold. Any leftover waste is simply thrown into the nearby river or piled up high in the streets, poisoning the children growing up here.
So what can you do with your e-waste? Robert Houghton, President and founder of Redemtech, an asset management and recovery firm, recommends you vote with your dollar. Buy from companies who have a take-back program that guarantees your discarde electronics are handled proper.
“ Consumers want to do business with companies who are demonstrably    good with corporate responsibility and dealing with e-waste, ” said Houghton.
There are   plenty of charitable   organizations that will    take your  used electronics and donate them for charitable causes:
? Electronic Recycling  Association (Canada) (ERA) collects old    computers for donation to libraries and other organizations across Canada.
? eBay’s Rethink Initiative pairs up consumers with businesses that refurbish (再磨光)old computers for donation.
? TechSoup has a thorough   listing of resources for those who would  like   to donate or recycle hardware，buy recycled hardware or find a refurbisher.
? The Charitable    Recycling Program  accepts all cell-phones    and    has a listing of charities it helps with its program.
? Call2 Recycle has set up drop off points across Canada in a number of stores. You can drop off your cell-phone and also your rechargeable batteries from handheld electronic products.
小題1:When there is something wrong with electronics, what is a popular trend among people nowadays?
A．To keep a DIY way.B．To put them away themselves.
C．To purchase what they like.D．To donate them to charities.
小題2:Guiyu city in Southeastern China is mentioned here to show us ____.
A．there is an ideal place in the world for e-waste
B．there is a good example in the world for recycling
C．the recycling events in Canada benefit people overseas

Against the supposition that forest fires in Alaska，Canada and Siberia warm the climate，scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions.Usually large fires destroyed forests in these areas over the past decade.Scientists predict that with climate warming，fires may occur more frequently over the next several centuries as a result of a longer fire season.Sunlight taken in by the earth tends to cause warming，while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate.Earlier studies by other scientists had suggested that fires in northern regions sped up climate warming because greenhouse gases from burning trees and plants were released into the atmosphere and thus trapped heat.
Scientists found that right after the fire，large amounts of greenhouse gases entered the atmosphere and caused warming.Ozone (臭氧) levels increased，and ashes from the fire fell on far­off sea ice，darkening the surface and causing more radiation from the sun to be taken in.The following spring，however，the land within the area of the fire was brighter than before the fire，because fewer trees covered the ground.Snow on the ground mirrored more sunlight back into space，leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere，” scientists said.They tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire，and found a measurement closely related to the global air temperature.Typically，fire in northern regions occurs in the same area every 80 to 150 years.Scientists，however，found that when fire occurs more frequently，more radiation is lost from the earth and cooling results.Specifically，they determined when fire returns 20 years earlier than predicted,0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases，but 0.9 watts per square meter will be sent back into space.The net effect is cooling.Watts are used to measure the rate at which energy is gained or lost from the earth.
小題1:According to the new findings，taking steps to prevent northern forest fires may________.
A．result in a warming climate
B．cause more forest fires
C．lead to a longer fire season
D．protect the forests there
小題2:The following are the immediate effects after a forest fire EXCEPT________.
A．large amounts of greenhouse gases enter the atmosphere
B．the levels of ozone which is a type of oxygen increase
C．snow on the ground mirrors more sunlight back into space
D．ashes from the fire fall on the ice and darken the surface
小題3:Earlier studies about northern forest fires________.
A．had analyzed all aspects of how northern fires influenced climate
B．had indicated that forest fires would pollute the atmosphere
C．had suggested that people should take measures to protect environment
D．had suggested that the fires would speed up climate warming
小題4:We can infer that forest fires in Alaska，Canada and Siberia may________.
A．warm the climate as the supposition goes
B．cool the climate by reflecting more sunlight into atmosphere
C．make more space for the growth of young trees
D．help to gain more energy rather than release more energy

Founded in 1966，Seacamp，the first program dedicated to the education of youth in marine(海洋的) sciences，is the result of a cooperative effort of parents，scientists，businessmen and camp leaders.Preservation practices and a respect for the marine environment are the philosophy of the Seacamp.
Seacamp’s tropical marine location in the lower Florida Keys enables it to offer a truly unique marine science program.This program is the heart of Seacamp.Young scientists participate in a variety of courses under the guidance of academically trained marine science instructors and biologists.All science activities include studies in both the field and the laboratory.Each session,140 to 160 campers come to Seacamp，mostly from the US，but also from across the world.There are about 30 international campers each summer from an average of twelve countries.Many Seacamp program graduates have gone on to careers as environmental educators and marine scientists.
One of Seacamp’s unique aspects is that campers create their schedules.In addition to science classes，campers choose from a variety of programs to ensure that there is something interesting and exciting for everyone.Campers interested in journalism may work on the camp newspaper，SEASCOPE，which is published periodically during camp sessions.Arts activities are also included.Photography allows campers to take home memories of friends，wildlife，and underwater experiences.
Seacamp teaches the fun and skills of sailing.It’s an excellent way for future marine scientists to become familiar with the winds，tides and currents that are of primary concern in oceanography.Basic Red Cross certification is offered to beginners in sailing.The Red Cross course in advanced lifesaving is taught at Seacamp.The course is designed to increase the campers’ ability to recognize and avoid dangerous water conditions and practices and to use self­rescue skills to get out of dangerous situations.
Parents may bring campers by car to Big Pine Key.Counselors(輔導員) also meet participants at the Miami International Airport on the opening day of camp and accompany them to Big Pine Key on a bus.The fee for round­trip service is $90.To join the Seacamp adventure，interested campers should contact Seacamp for an application.
We love to talk about camp！For more information or to ask any questions you might have，please give our friendly staff a call and we’ll be glad to help!

According to body language expert Robert Phipps，the way people sleep at night actually determines a lot about the type of personality they have.Phipps has identified four sleeping positions that affect personality.
Phipps found that worriers，those who stress the most，tend to sleep in the fetal(胎兒的)position.He found that this is the most common bedtime position，with nearly 58 percent of people sleeping on their side with knees up and head down.The more we curl up(蜷曲)，the more comfort we are seeking，according to Phipps.
The second most common position is the log.Sleeping with a straight body，with arms at each side，as if they are standing guard at Buckingham Palace，indicates stubbornness，and these people(the 28 percent who sleep this way)often wake up stiffer than when they went to sleep.
“The longer you sleep like this，the more rigid your thinking is and you can become inflexible，which means you make things harder for yourself，”according to Phipps.
Yearner(向往型)sleepers are next on the list.About 25 percent of people sleep in this style—on their side with arms stretched out in front，looking as if they are either chasing a dream or perhaps being chased themselves.Yearners are typically their own worst critics，always expecting the best results，explained Phipps.These people often wake up refreshed and eager to face the challenges of the day ahead.
Perhaps the most peculiar(奇怪的)of sleep styles is the freefaller position.This sleep style makes up 17 percent of the population.They sleep face down with arms stretched out.These people，according to Phipps，feel like they have little control over their life.Not only is this the strangest of sleep styles，but also the least comfortable，and people may wake up feeling tired and have no energy.
In conclusion，Phipps has only one more thing to add：“A good night's sleep sets you up for the following day and our sleeping positions can determine how we feel when we wake.”
小題1:Which of the following is the best title of the passage?
A．A Good Night's Sleep Sets You Up for the Following Day
B．Your Personality Depends a Lot on How You Sleep at Night
C．How You Sleep at Night Affects What You Do the Next Day
D．Which Sleeping Position Helps You Sleep Comfortably
小題2:Which of the following pictures is the fetal position?

小題3:The underlined word“rigid”is closest in meaning to “________”．
A．stubbornB．flexible
C．comfortableD．strange
小題4:Which of the following shows the structure of the passage?
CP：Central 　P：Point　Sp：Sub?point

Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.
"Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
"Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded.
小題1:According to the passage, students who date in middle school may_____
A．have poorer academic performances
B．be more likely to hurl others
C．enjoy better school lives
D．are less likely to use alcohol and tobacco
小題2:When doing his study, Orpinas_____.
A．followed a group of students of 6th and 12th grade
B．completed a survey and a report each year
C．completed questionnaires about the students’ academic efforts
D．found that the students’ study skills have connection with their frequency of dating
小題3:Study skills may include the following behaviors and qualities Except_____
A．being diligentB．being well organized
C． being kind and helpfulD．finishing assigned schoolwork
小題4:What can possibly happen to the school couples after they break up?
A．They don’t want to see each other any longer.
B．Their attention to studying will be affected.
C．They will miss their ex-partners sometimes
D．They will think it reasonable to get depressed.
小題5:Orpinas’ attitude towards dating in middle school is_____
A．supportive B．positiveC．negativeD．indifferent

Anyone who doubts if children are born with a healthy amount of ambition need spend only a few minutes with a baby eagerly learning to walk. No matter how many times the little ones stumble in their first efforts, most keep on trying, determined to master their amazing new skill. It is only several years later, many psychologists and teachers agree, that a good number of kids seem to lose their natural drive to succeed. For the parents of such kids, whose own ambition is often tied to their children's success, it can be a painful experience.
Figuring out why the fire went out is the first step. Assuming that a kid doesn't suffer from a learning disability, or isn't involved in some family crisis(危機) at home, many educators attribute a sudden lack of motivation to a fear of failure or classmate pressure.“Everything is within the kids' control；their intelligence is changeable,”says Lisa Blackwell, a research scientist at Columbia University. More than any teacher or workshop, Blackwell says,“Parents can play a key role in conveying this message to their children by praising their effort and progress rather than emphasizing their “smartness” or praising high performance alone. Most of all, parents should let their kids know that mistakes are a part of learning.”
Some experts say our education system, with its strong emphasis on testing and separation of students into different levels of ability, also bears blame for the disappearance of drive in some kids.“These programs shut down the motivation of all kids who aren't considered gifted and talented. They destroy their confidence,” says Jeff Howard, a social psychologist. Howard and other educators say it's important to expose kids to a world beyond homework and tests, through volunteer work, sports, hobbies and other extra­curricular activities.
“The problem of the issue is that many students experience education as irrelevant to their life goals and ambition,”says Michael Nakkual, a Harvard education professor. The key to getting kids to aim higher at school is to free them of the idea that class work is irrelevant, and to show them how doing well at school can actually help them fulfill their dreams beyond it. They need to understand that you have to learn to walk before you can run.
小題1:According to the passage, the parents of kids with no ambition ________.
A．don't do a very good job on teaching them to walk
B．are to blame if the kids do poorly in school
C．feel pain because their own ambition is connected to their kids' success
D．should take part in extra­curricular activities with kids
小題2: The underlined part “the fire went out” probably means ________.
A．the motivation was suddenly lost
B．the fear of failure was suddenly gone
C．the learning disability was suddenly lost
D．the fire was suddenly gone
小題3:All the following can contribute to a sudden lack of ambition EXCEPT ________.
A．learning disabilityB．classmate pressure
C．emphasis on testingD．extra­curricular activities
小題4:What is the most important thing for parents in motivating their kids?
A．Punishing kids who don't display ambition.
B．Emphasizing smartness and high performance.
C．Telling kids that mistakes are a part of learning.
D．Praising the effort and progress they have made.

There are quite a few advantages of wearing school uniforms. The idea may seem disagreeable at first, but considering all the positive effects coming from wearing uniforms you would be more likely to enjoy them.
Teachers love school uniforms because it helps provide an orderly learning environment. Having students dressed in uniforms may teach them how to present themselves in a neat and professional manner. It gives students the opportunity to learn how to dress like young ladies and gentleman. And they can focus their attention on academics rather than style.
Purchasing (購買) school uniforms is easy and needs less hesitation and consideration. No matter what the school’s policy is, there are only specific essential (基本的) pieces to the wardrobe (服裝) that are necessary, so it won’t break the bank. A few wardrobe items can last a long time. Parents could also enjoy an easy morning, as it will take less time to choose a set of clothes for the school day.

Getting dressed before school becomes less of a chore(瑣事) when students are limited in their choices, so there shouldn’t be any trouble about choosing an outfit for the day and getting ready quickly. Some students may not like the lack of individuality(個性) with a uniform, but some school dress code policies may offer them the opportunities to show their unique styles.
Uniforms today are also becoming trendier and can be seen in many areas of pop culture. Celebrities(名人)and fashion designers are using uniforms as inspiration for new looks which also appeal to students.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection. ,科Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement（侵犯）. Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties（版稅）. In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because _____________.
A．people did not know how to put out the fire
B．Elias Howe thought Thimonnier had stolen his invention
C．the sewing machines was couldn’t work finally
D．workers who feared the loss of their jobs to a machine set fire
小題2:Which of the following is NOT TRUE according to the passage?  
A．Singer is an American inventor and manufacturer.
B．The Singer sewing company became more practical.
C．The foot treadle helped to make the sewer’s hands free.
D．Singer made improvements to the design of sewing machines.
小題3:Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?
A．Because the judge was against Singer for his surly attitude.
B．Because Howe had already patented the lockstitch used by Singer.
C．Because Singer had borrowed money from Howe and never repaid it.
D．Because Singer and Howe had both invented the same machine.
小題4:Which of the following would be the best title for this passage?
A．A Stitch in Time Saves Nine
B．The Case between Howe and Singer
C．Patent Laws on the Sewing Machine
D．The Early History of the Sewing Machine
