We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans,  killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-­year ­old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute,
has discovered a way to make plastic bags degrade(分解) in as few as 3 months, a finding that won him first prize at the Canada－Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue.
Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted(調(diào)制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” said Daniel Burd.
小題1:Daniel Burd won first prize at the Canada－Wide Science Fair because________.
A．he found a new kind of microorganism
B．he contributed much to environmental protection

Kids have their own ideas about money---some are sensible and others are not so wise.
Twelve-year-old Amanda thinks it’s        to save and not blow your money right away  “ so you can         other things”.
When it comes to credit cards, eight-year-old Jeremie says when the monthly        comes in “ you sign it and then you give it back” ---leaving out the part about actually        it.
These kids are        far away from the working world, but the ideas they’re forming about        could affect how much they save, how they use credit cards and how much debt they finally take on in later life.
High school business teacher Jeff Balch said his students had        knowledge about money other than spending. “ They don’t know most things because        talks to them about them---as in their parents,” said Balch, “The discussions tend to be in terms of kids        too much money, but no one tells them why, where their money goes.
Mitch Murphy said students’ message to the task force was to “ make it       ”. “ It may be difficult to have a 14-or 15-year-old student get too        about retirement planning, ” Murphy said, “ But if you want to talk about a cellphone contract or a debt card,they will be engaged in.” Murphy said learning financial literacy (能力)　    ,  well        getting into the work force, should stay with Canadians for life and        the country as a result.
Sandra Martin said children can start learning about money when they learn to       . “ Sit down with the flyers and look at how much things cost,” Martin said. Babysitting and birthday money could be        and there would be a(n)        as to how much could be debited(借) every month, she said.
“ The reality is that we’re not spending with cash anymore. If you’re always in         of your child’s money, then they’re never going to learn what it means to save for something that’s      .”
Balch said he tries to make his students realize the differences between needs, wants and priorities(優(yōu)先權(quán)). If they haven’t learned self-control and if they haven’t learned how to        money, they can easily spiral(螺旋上升) out of control.

The next time your face turns red after tripping(絆倒) over your own feet in public, don’t try to hide it—a new study finds that showing your embarrassment actually makes other people view you as more reliable.
Researchers at the University of California have carried out the study and found that embarrassment is a good signature of a person to whom you can entrust valuable resources.
Not only are the findings useful for people seeking cooperative and reliable team members and business partners, but they also make for helpful dating advice.“Moderate(適度的) levels of embarrassment are signs of virtue. Our data suggests embarrassment is a good thing, not something you should fight.”said Matthew Feinberg, who led the study.
While the most typical gesture of embarrassment is a downward gaze to one side while partly covering the face, a person who feels shame, as distinguished(區(qū)別) from embarrassment, will typically cover the whole face, Feinberg said.
The results were got from a series of experiments. In the first experiment, 60 college students were videotaped describing embarrassing moments, such as making incorrect assumptions(假想) based on appearances. The college students also participated in the “Dictator Game” which is used in economics research to measure altruism(利己主義). For example, each was given 10 raffle tickets(獎(jiǎng)券) and asked to keep a share of the tickets and give the reminder(提示物) to a partner.
The findings, published in the Journal of Personality and Social Psychology, showed that those who showed greater levels of embarrassment tended to give away more of their raffle tickets, indicating(﹦showing) greater generosity.
小題1:According to the passage, which of the following is thought to be reliable?
A．A person who feels shame.
B．A person who hides his embarrassment.
C．A person who shows his embarrassment.
D．A person who gives away more raffle tickets.
小題2:We can infer from Paragraph 3 that ________.
A．it’s useless to fight our embarrassment
B．people should try to overcome their embarrassment
C．embarrassed people are not good at doing business
D．people who show embarrassment can be good business partners
小題3:The “Dictator Game ” is used to _________.
A．measure the students’ economic status
B．test whether a student is generous or not
C．determine the different levels of embarrassment
D．record how each student reacts during embarrassing moments
小題4:We learn from the last paragraph that those who showed greater levels of embarrassment ____.
A．proved to be more generousB．kept more of the raffle tickets
C．didn’t care for raffle ticketsD．were less reliable

Expensive and new gloves allow chatterboxes（話匣子）to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves are known as “Talk to the Hand” and cost £1,000 a pair. They fixed a speaker unit into the thumb and a microphone into the little finger that can be connected to any mobile handset using Bluetooth.
Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned（承擔(dān)）the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.
Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale. O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to £260 to those who recycle gadgets including phones, handheld consoles, MP3 players and digital cameras.
Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my ‘Talk to the Hand’ project will get people to think again about the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim.”
Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There’s a pressing need for all of us to look at outdated handsets, and all the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”
小題1:The underlined word “O2” in Paragraph 2 is probably the name of ______.
A．a(chǎn)n artistB．a(chǎn) companyC．a(chǎn) mobileD．a(chǎn)n exhibition
小題2:Consumers can buy the “Talk to the Hand” gloves ______.
A．in the exhibition
B．from Mr Miles
C．when they are mass produced
D．a(chǎn)fter they recycle the gadgets
小題3: The purpose of the project is to _______.
A．promote the technology of IT
B．enable people to talk to their hands
C．raise people’s awareness of recycling
D．a(chǎn)ttract visitors’ attention in the exhibition
小題4:What is the passage mainly about?
A．New mobiles that are fashionable.
B．Outdated handsets that are upgraded.
C．Outdated gadgets that can be used for recycling.
D．New gloves that can be used for making phone calls.

Unlike traditional commercials, Public Service Advertisements（PSA）are primarily designed to inform and educate rather than sell a product or service. The goal of a PSA is not to make a big sale, but rather to change public opinion and raise awareness for a problem.
Smokey Bear has been a recognized symbol of the protection of America’s forests from fire. It is created to educate the public about the dangers of wildfires. Smokey Bear was started in 1944 with the slogan, “Smokey Bear Says—Care will prevent 9 out of 10 forest fires”. Smokey Bear’s later slogan,  “Remember! Only You Can Prevent Forest Fires”, was created in 1947 by the Advertising Council in America. In April 2001, the message was changed to “Only You Can Prevent Wildfires”.
The wildfire prevention campaign with Smokey Bear is one of the longest and most successful campaigns in advertising history. The Advertising Council often was in partnership with other organizations and groups to create various advertising for Smokey Bear since 1944.
The Advertising Council teamed with Walt Disney Company to create a series of PSAs. The ads feature（以···為形象）characters form the classic film Sleeping Beauty and aim to reach parents and children. The lovely Bambi also appeared in the advertisements. Mickey Mouse is much more popular throughout the country.
Those PSAs, which appear on television, on the radio, in the newspaper and on the website continue to remind Americans about the importance of wildfire prevention have helped to reduce the number of acres burned annually by wildfires. According to recent survey, Smokey Bear and his famous words of wisdom “Only You Can Prevent Wildfires” are recalled by 3 out of 4 adults.
In addition to the PSA campaign, Smokey Bear has his own U.S. postage stamp and website for more information about wildfire prevention. From the website, you can also learn all about wildfires and how we can protect our forests.
小題1:PSA are primarily designed to     .
A．educate the publicB．change people’s status
C．discuss a problemD．sell products or services
小題2:Which of the following is true of the Smoky Bear?
A．It is one recognized symbols of Walt Disney cartoons.
B．It firstly appeared in America in 1944 with no slogan.
C．It is created to warn Americans of the dangers of wildfires.
D．Its slogan changes every three years.
小題3:How does the author support his topic in Paragraph 4?
A．By summing up.B．By giving examples.
C．By comparison.D．By asking questions.
小題4:According to this text, Smoky Bear      .
A．helps a lot to reduce wildfires in America
B．isn’t popular among the American pupils
C．has set up its own website to advertise products
D．becomes the symbol of the Advertising Council

The smallest animal with a backbone（脊椎） known to science, a fish from the carp family, has been discovered in the peat swamps （沼澤）of Indonesia. Mature（成熟的）females of the fish species （種類）Paedocypris reach just 7.9mm in length.
The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London.
“This is one of the strangest fish that I’ve seen in my whole career,” Dr Britz said. “It’s tiny, and it lives in acid. I hope that we’ll have time to find out more about them before their habitat disappears completely.”
The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else.
The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost.
“Many of the peat swamps we surveyed（調(diào)查）throughout South-East Asia no longer exist,” Dr Britz said. “Populations of all the miniature（微型的）fish of peat swamps have decreased or disappeared.”
Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.
小題1:64.Which of the following would be the best title for the passage?
A．The Strangest Fish
B．Acidic Peat Swamps

School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to learn some facts or a formula by heart. It is actually quiet easy to learn a certain fact in history or a formula(公式) in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientist, such as Einstein, Newton and Galileo, didn’t get everything from school. But they were all so successful and invented so many things for men. They worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.
小題1:According to the passage, a good teacher should be one who is to_________.
A．help his students to gain a good memory.
B．train his students’ ability to learn
C．teach his students everything he knows
D．have his students studying long hours
小題2:If a student want to learn better, the most important thing for him to do is_______.
A．to learn all the useful facts and formula by heart
B．to do everything as his teacher have said in class
C．to absorb (吸收) as much knowledge from his teacher as possible
D．to think more while he is studying
小題3:The main reason for the success of the great scientists is that________.
A．the teachers who had taught them were all experienced.
B．they used to work and study without a moment’s rest.
C．they had received more schooling than other people
D．they know how to study and worked hard
小題4:What’s the good advice the writer gives us?
A．We can learn better without teachers
B．We should do more asking and thinking while studying
C．We should pay enough attention to classroom
D．Book knowledge is of little use

How long you live has a lot to do with your environment and lifestyle, but exceptional(特別的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因譜)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(標(biāo)志基因組). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
小題1:Which of the following is TRUE according to Paragraph 2?
A．Most long-living people have special long-life-related genes.
B．Ninety percent of the participants lived to 100 years of age.
C．All the long-living people have only one signature genetic cluster.
D．Scientists know how the integration of the genes helps people live long.
小題2: Perls may most likely agree that         .
A．most people living extremely long benefit from not smoking
B．living longer just depends on certain genetic recipes
C．environmental factors play an important role in long-living
D．being mentally active has nothing to do with living an old age
小題3: Which of the following is FALSE according to the text?
A．Remaining socially engaged helps a person to live long.
B．A genetic recipe can accurately predict who may live to 100 and beyond.
C．Perls is the first to think living longer is just a matter of genes.
D．The older he gets, the more likely the genes contribute to his extended years.
小題4:Which of the following would be the best title for the text?
A．Genes May Predict Who Lives to 100B．Environment And Genes
C．Genes, the Secret of Long LivingD．Lifestyle And Genes

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino （厄爾尼諾）. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韋）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication（出版物）Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
小題1:El Nino is known as ___.
A．the changing of the weather in southern Africa
B．the warming of waters in the Pacific Ocean
C．the weather which brings drought（旱災(zāi)）to Africa
D．the weather phenomenon（現(xiàn)象）that brings heavy rains to Africa
小題2:Scientists study El Nino in order that ___.
A．they can provide a kind of early warning to the place that will suffer from drought
B．they can tell why Zimbabwe has little or no rain
C．they can do some research work in this field.
D．they can put all this information into their computers.
小題3:Which of the following is TRUE according to the passage?
A．Scientists come to understand how El Nino appears.
B．Three scientists from the USA work on this subject.
C．Southern Africa suffered a serious drought and many people died from hunger.
D．El Nino has something to do with Zimbabwe’s poor crops.
小題4:Which of the following is NOT true according to the article?
A．The computer is used in this research work.
B．Scientists know when an El Nino appears by means of the computer program.
C．The scientists published their results of the research work.
D．Nature is the name of the article written recently by the scientists.
小題5:What’s the best title for this passage?
A．Appearance of El Nino is Predictable（可預(yù)測(cè)的）
B．Drought in Zimbabwe
C．Early Warning System
D．Weather in Africa
