It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”
You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不見的) blanket.
Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

My son loves video games very much. He spends hours every day playing video games in his room. Is there any redeeming（補(bǔ)償?shù)模〆ducational value to video games? Some seem like they could help him learn strategy. But I worry others may be too violent or numb（使麻木）his mind.

Some games may improve kids’ hand-eye coordination and problem-solving skills. Games that require kids to actually move or manipulate（操縱）the game through their own physical movement can even get sedentary kids moving, though not as much as they could if they actually played outside or participated in sports or other outdoor acuities. Others, though, don’t have such benefits, and violent video games have been shown that they might increase kid’s aggressive behavior.
Like a lot of aspects of raising kids, when it comes to video games, the healthiest approach is actually self-control.
The American academy of Pediatrics(AAP) recommends that kids should spend no more than 2 hours each day on screen time, including watching TV or movies, or playing computer or video games. So consider setting limits at least that strict to keep game playing from affecting their schoolwork, household responsibilities, and the physical activity your son needs very day.
Make sure that he’s playing games which are suitable for his age group. All video games are rated and labeled by the Entertainment Software Rating Board. Steer clear of（避開）any rated “M” for mature. Those are for ages 17 and older and can contain heavy-duty violence, strong language, and sexual content.
Try to keep the video game console（游戲機(jī)控制板）in a common area of the house, not your son’s room. That way you can catch any inappropriate content in the games he’s playing, and he’ll be in a position to interact with others in the house while he’s playing.
Make sure your son has appealing alternatives, too, such as sports, activities, opportunities to socialize with peers; and downtime to be creative. If you continue to have concerns about his video game activity, talk with your doctor.

The quality of water supply in southern Beijing has been improving in recent years, an official said.
In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform.
"The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said.
In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said.
Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing.
Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances, he said.
According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants.
The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said.
The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said.
Many new communities in southern Beijing are equipped with a network to recycle water.
In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it.
Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015.
Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely heavily on low-end industries such as cement factories and small coal mines, being turned into a bustling commercial center and home to many educational institutions.

What is colour? Why do some of the things around us look red, some green, others blue?
　Colours are really made by reflected(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
　Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat(熱能).The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.
小題1:When something reflects light, we can_______.
A．see its colourB．see its heatC．not see its colourD．see nothing
小題2:In summer _____make people feel cool.

Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste.
In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away.
But instead of being buried in land, some feathers could find a future in plastics（塑料）.
One of the products they have developed is a flowerpot（花盆）. It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it breaks down, it naturally becomes nutrient（營(yíng)養(yǎng)物） in the soil.
The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private（私人） organization（組織）.
Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics.
He says feathers are much stronger and last（持續(xù)） longer than another plant material. "Feathers are stronger. By design, feathers are also more durable（耐用的）. And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly."
He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used.
"Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt.
Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two.
小題1:What do people mainly deal with feathers?
A．Feathers are used to make pillows, coats and other products.
B．Most feathers are paid no attention to.
C．Most feathers are used as nutrient
D．Most feathers are used to make flowerpots
小題2:What’s the advantage of the flowerpots?
A．They won’t last long. B．They can’t break
C．They are environmentally friendlyD．They can be reused
小題3:What does Walter Schmidt think of traditional flowerpots?
A．Too heavyB．Too old
C．Never re-usedD．lasting longer but unnecessary
小題4:What do you think is the main idea of the passage?
A．Chicken and its feathersB．How to deal with feathers
C．feathers made into flowerpotD．New flowerpots

As a senior high school student, my future is always on my mind. To be exact,thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort.Steve Jobs gave a speech to Stanford's graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.
It started when l became a junior, when college came into view.  It's the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn't mean that students shouldn't attend college, but rather that they shouldn't worry so much.  You'll get where you need to go, even if your path is a bit morewinding(蜿蜒的)than you'd like.
Jobs talked about the hardships in his work.  His love of his work helped him carry on and he got where he was meant to be, which restates the point: don't panic.One particular part of his speech stayed with me.  Steve Jobs quoted(引用)thc saying"Stay hungry, stay foolisll" and it has become my motto. Staying foolish is realizing thatyou are still a fool, no matter how much you've learned or experienced.  There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs' level of success is possible to achieve, and I aim to prove that. With the will power to go into the world living every day like it's my last and allowing the future to take care of itself, I will do great things.  In the last moments of my life, I'll be proud of what I have done and hope to have all the wisdom a person could wish for.

There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century．
In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India．In order to reduce fraud（詐騙）, he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay．This finding inspired him to begin investigating fingerprints．In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system．Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist (優(yōu)生學(xué)家). Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system—the first existence．
Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system．In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, they matched Rojas' exactly．She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy（指紋鑒定法）. It's still used in many Spanish-speaking countries．
Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world．
小題1:Herschel had people record their fingerprints so as to_____．
A．develop a fingerprinting systemB．prevent illegal business
C．put them on pieces of clayD．collect and study fingerprints
小題2:Who first came up with the idea of creating a fingerprint classification system?

A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men.
　　The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue of Psychological Science.
　　Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, “What do you regard as your most serious fault of personality or character?”
　　Pessimists were defined as fatalistic(宿命論的)people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation.
　　Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide).
　　A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely(不適時(shí)的) death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. “A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later,” according to Peterson.
小題1:According to the passage, you may be a pessimistic person, if one failure makes you feel________.
A．other people have been unfair to you.
B．other people will help you.
C．you cannot change a bad situation.
D．you can do better next time.
小題2:According to the passage, pessimists may feel all of the following EXCEPT________
A．helpless when faced with difficulties.
B．cheerful when faced with troubles.
C．hopeless when one bad event occurs.
D．guilty when things go wrong.
小題3:Which of the following statements is true, according to the passage?
A．Pessimists believe that everything in life depends on fate.
B．There are more pessimists among women than among men.
C．Most pessimists will end up committing suicide.
D．All pessimists will eventually die from accidents.
小題4:The Terman Life-Cycle Study is a research program that studies________.
A．people over 70 years old.
B．people since their childhood.
C．pessimistic people over 80 years old.
D．only younger people.
小題5:The analysis made by Christopher Peterson and his colleagues shows that pessimistic people________
A．will die from violence if they learn to be optimistic.
B．will more likely die from violence than optimistic people.
C．will die from violence because their IQs are low.
D．will die untimely if they are not able to learn to be cheerful and optimistic.
