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.

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?
小題1:What is mainly described in the passage?

A．A historic discovery.	B．An event of imagination.
C．A research on space.	D．A scientific adventure.

小題2:When the first piece hits the South Atlantic, it causes .

A．an earthquake	B．damages to cities
C．an Earth explosion	D．huge waves

小題3:Why can’t the northern half of the earth escape for long?

A．Because the land is covered with water.

B．Because the light and heat from the sun can not reach the Earth.

C．Because people there can not live at the temperature of zero.

D．Because wars break out among countries.

小題4:By giving the example of dinosaurs, the author tries to prove .

A．animals could not live in the cold climate

B．what happened 65 million years ago was an invented story

C．the human beings will die out in 2094

D．the Earth could be hit by other objects in space

Do you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since researches have shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空間的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries—why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎兒) are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier (障礙物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research. www. .com
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.
小題1:Which of the following is true according to the first paragraph?

A．Women’s brain is 10% less than men’s

B．Grey matter plays the same role as white matter.

C．Grey matter controls thinking in the brain.

D．Both sexes have the same amount of white matter.

小題2:What can we infer from the second and third paragraphs?

A．Women prefer doing many things at a time.

B．Men do better dealing with one job at a time.

C．Women do not need to tell directions.

D．Men have weaker spatial abilities.

小題3:Which of the following do you agree with according to the fourth paragraph?

A．Young boys may be stronger than young girls.

B．More women take up jobs requiring speech skills.

C．Women may have stronger feelings than men.

D．Our ancestors needed more spatial skills.

小題4:What is the writer’s attitude in writing this passage?

A．Defensive.

B．Persuasive.

C．Supportive.

D．Objective.

For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man’s assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training.
Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.
Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective (有缺陷的) or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct.
Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize (訂制) babies before they are born just like picking options at a car store.
小題1:According to the first paragraph,______ .
A. man-made evolution has improved all species
B. man-made evolution has weakened some species
C man-made evolution can make up for all natural losses
D. natural evolution won’t happen without man’s assistance
小題2:What does the underlined part “taken a back seat to” in Paragraph 2 mean?
A. Become powerful assistance to.
B. Become a huge barrier to.
C Speeded up the process of.
D. Played a less important role than.
小題3:What does the third paragraph mainly talk about?

A．Why natural evolution happens so slowly.

B．The way scientists adopt to have genetic defects repaired.

C．The advantages of man-made evolution over natural evolution.

D．How scientists make use of man-made evolution to create new species.

小題4:What can we infer from the passage?

A．Near-sighted parents will be able to produce babies with good eyesight in the future.

B．Doctors and scientists will be responsible for mass production of babies in the future.

C．It is natural evolution that is to blame for the destruction of European wolves and mammoths.

D．Children can now have their memory and intelligence improved with the help of gene treatment.

All around the world, shoppers flock to Wal-Mart to buy everything．In Texas, they come for another reason: to see the wind turbine(渦輪機) , which supplies 5% of the store's electricity．It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant．
The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods．It throws its weight behind environmental responsibility, and the impact could be amazing．"One little change in product packaging could save 1, 500 trees," says Wal-Mart CEO Lee Scott．"If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference．"
Scott wants Wal-Mart to do its part too．He has promised to cut the existing greenhouse-gas emissions （排放） over the next few years and promised to construct new stores that are more efficient．He wants Wal-Mart's fleet (車隊) of more than 7, 000 trucks to get twice as many miles per gallon by 2015．Factories that show Wal-Mart they're cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it's working with consumer-product manufacturers to reduce their packaging and will reward them if they do so．
Some people may doubt it is a bid to attract attention from Wal-Mart's controversial labor and health-insurance practices．But it's not just window dressing, because Wal-Mart sees profits in going green．Scott says, "This is a business philosophy, not a social philosophy．We don't go where we don't think there's a great interest in change．"
Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart's image at a time when his company's reputation is declining．He acknowledges that he launched the plan partly to shield （保護，庇護） Wal-Mart from bad press about its contribution to global warming．" By doing what we're doing today, we avoid the headline risks that are going to come for people who did not do anything," he says．"At some point businesses will be held responsible for the actions they take．" Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit．
小題1:We can infer from the passage that ______．

A．Lee Scott is Wal-Mart's CEO

B．there are 5, 200 stores in the world

C．Wal-Mart has a great influence on the world market

D．Wal-Mart has more than 7, 000 trucks all over the world

小題2:What does the underlined sentence "This is a business philosophy, not a social philosophy．" mean in the fourth paragraph?

A．Wal-Mart predicts huge profits in its green activity．

B．Wal-Mart's green activity is just window dressing．

C．Wal-Mart aims to solve its health-insurance practices．

D．Wal-Mart doesn't have any social responsibility at all．

小題3:What will Wal-Mart probably do in the future?

A．Reduce air pollution in its present stores．

B．Give favorable treatment to its consumers．

C．Ask the factories to reduce their packaging．

D．Demand the fleet of trucks to use more fuel than before．

小題4:What is the main idea of the last paragraph?

A．Provide the background of the green plan．

B．Stress the purpose of Wal-Mart's green plan．

C．Present the risk that Wal-Mart is facing nowadays．

D．Analyze the similarity between Bill Gates and Scott.

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

C．he found a way to degrade plastics in shorter time

D．he could encourage microbes growth in an easier way

小題2:Daniel Burd exposed one plastic sample to dead bacteria to ________.

A．make the live bacteria work better

B．test how effective his method was

C．know which bacteria worked faster

D．control the temperature in the process

小題3:Maintaining the required temperature takes little energy because ________.

A．plastics can get hot easily

B．microbes can produce heat themselves

C．much carbon dioxide is produced

D．the temperature can be controlled

小題4:Daniel Burd got his idea from ________.

A．his school textbook	B．the failure of researchers
C．his everyday work	D．the practice of other people

Recently a Beijing father sent in a question at an Internet forum(論壇) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行話) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!
小題1:By writing the article, the writer tries to .

A．explain some Internet language

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either ．
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind ．If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping （feeling of cold, a noise, a discomfort, etc．） and it may also use your past experiences and the wishes and the interests you have now．This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom．
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment．A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton．He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean．Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem．They believe that dreams are mostly expressions of wishes that do not come true．In other words, dreams are a way of having your wishes carried out．
小題1:From the passage we know that our dreams ___________.

A．are imagination of our daily life

B．are man’s curious look into the future

C．have nothing to do with our feelings

D．are to some degree connected with our feelings

小題2:Older children often dream of examinations probably because ___________.

A．they are interested in exams

B．they are often worried about their studies

C．they hope for a better life

D．they show much interest in their studies

小題3:According to the writer , the explanation of dreams that some scientists made ___________.

A．is considered interesting , but unreasonable

B．gives a good answer to the question why we dream

C．has some value , though not fully convincing

D．has been proved by the findings of their studies

小題4:What is the best title for this passage ?

A．Why People Dream ?	B．New Findings about Dreams
C．Dream Makes Hopes	D．What Dreams Mean ?

If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live in are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography（海洋學）, your interests may be better served by attending school in a place that is on a coastline or near the ocean.
Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.
California is a nice state. Northern California specifically has very good weather. Los Angeles in southern California is another story, though. Life in LA is full of excitement and fast, and sometimes dangerous. As for me, I enjoyed the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as Northern California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.
Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature and peace? Then you probably should stay away from America’s large cities. Are you interested in government? Then Washington D. C. is the only place for you. Whatever you decide, put some thought into it. The place you live in could be the difference between a great study-abroad experience and a state of great suffering on earth.
小題1:What, according to the author, should be considered first if you want to study in the USA?

A．The climate	B．The scenery
C．The study condition	D．The living condition

小題2:What is California like?

A．California is the best place to live in.

B．California is the worst place to live in.

C．California is a state with the largest city.

D．California is a state with different climates.

小題3: If you study in Middle America, you can probably _______.

A．find the best universities

B．feel the real character of the nation

C．meet the most famous professors there

D．face more difficulties

小題4: What can we conclude from the text?
A.All American famous universities lie in nice places.
B. Los Angeles is the most dangerous city in the USA.
C. Washington D.C. is the political centre of the USA.
D. It is always raining in the Midwest of the USA.
