Disposing(處理)of waste has been a problem since humans started producing it.As more and more people choose to live close together in cities,the waste-disposal problem becomes Increasingly difficult.
During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site.Residents or trash haulers(垃圾拖運(yùn)者)would transport household rubbish,rotted wood,and old possessions to the site.Periodically(定期的)some of the trash was burned and the rest was buried.The unpleasant sights and smells caused no problem because nobody lived close by.
Factories,mills,and other industrial sites also had waste to be disposed of.Those located on rivers often just dumped the unwanted remains into the water.Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society.The first problem is space Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas rarely have empty land suitable for this purpose.Property is either too expensive or too close to residential(住宅區(qū)的) neighborhoods.Long-distance trash hauling has been a common practice but once farm areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city areas is almost nonexistent.
Awareness(意識(shí)) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however,continues to grow.
Recycling efforts have become commonplace,and many towns require their people to take part.Even he most efficient recycling programs,however,can hope to deal with only about 50 Percent of a city’s reusable waste.

A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou，Hunan Province on May 17.Nine people were killed and 16 injured.
Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them?
People are always racking their brains to find a way of preventing buildings’ collapse. Better materials and technology help，but they are not a solution.
Just like humans，a building has its own life cycle from “birth” to “death”．If we know when a building is going to collapse，we can repair it in advance or get out of it before it falls.
Now，scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports.
The research was led by Nancy Sottos，a professor at the university’s Beckman Institute，and Douglas Davis，a graduate research assistant.
The secret behind the colorchanging material is a type of molecule (分子)．A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle，holding hands. Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule. If one person lets go of his or her hands，the molecule changes color.
The research team put the molecule into a soft material. When the researchers stretched the material，it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red.
The major problem is that light can get rid of the red color. When the team shone bright light on the molecule，the broken bond was fixed，and the color disappeared.
If the bright light keeps the red color from appearing，the material’s warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab.
【小題1】What does the passage mainly introduce?
| A．The collapse of an overpass in Zhuzhou，Hunan Province. |
| B．The Sichuan earthquake |
| C．A material that turns red before it breaks. |
| D．A way of preventing building from collapsing. |
| A．suffering a lot | B．collecting beyond imagination |
| C．losing a lot | D．thinking very hard |
| A．Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn’t been warned. |
| B．There is no building that will never collapse. |
| C．A new material has been applied to buildings to warn people of collapse. |
| D．A colorchanging material can turn red before it breaks. |
| A．The colorchanging molecules are certain to be used outside the lab. |
| B．There will be no collapse with the help of the colorchanging material. |
| C．There is a long way to go before the material can be applied. |
| D．The problem caused by bright light will be solved by scientists. |

Throughout the world, boys and girls prefer to play with different types of toys. Boys typically like to play with cars and trucks, while girls typically choose to play with dolls. Why is this? A traditional sociological explanation is that boys and girls are socialized and encouraged to play with different types of toys by their parents, peers, and the “society”. Growing scientific evidence suggests, however, that boys’ and girls’ toy preferences may have a biological origin.
In 2002, Gerianne M. Alexander of Texas A&M University and Melissa Hines of City University in London surprised the scientific world by showing that monkeys showed the same sex-typical toy preferences as humans. In the study, Alexander and Hines gave two masculine toys (a ball and a police car), two feminine toys (a soft doll and a cooking pot), and two neutral toys (a picture book and a stuffed dog) to 44 male and 44 female monkeys. They then assessed the monkeys’ preference for each toy by measuring how much time they spent with each. Their data showed that male monkeys showed significantly greater interest in the masculine toys, and the female monkeys showed significantly greater interest in the feminine toys. The two sexes did not differ in their preference for the neutral toys.
If children’ s toy preferences were largely formed by gender socialization, as traditional sociologists’ claim, in which their parents give “gender appropriate” toys to boys and girls, how can these male and female monkeys have the same preferences as boys and girls？They were never socialized by humans, and they had never seen these toys before in their lives.
【小題1】Traditional sociologists believe boys’ and girls’ toy preferences ________.
| A．a(chǎn)re passed down from their parents |
| B．a(chǎn)re largely formed in later life |
| C．have nothing to do with gender socialization |
| D．have a biological origin |
| A．a(chǎn)lso have a sex typical toy preference |
| B．a(chǎn)lso play toys as humans do |
| C．have no toy preferences |
| D．like to play different toys at different time |
| A．find more evidence for traditional sociology |
| B．test the intelligence of monkeys |
| C．test whether monkeys like to play toys |
| D．find out why boys and girls prefer different toys |
| A．only the male monkeys showed interest |
| B．the female monkeys showed more interest |
| C．the male and female monkeys showed the same interest |
| D．neither the male nor the female monkeys showed any interest |

When 18th-century scientists first came across Australia’s platypus(鴨嘴獸), they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal.
While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (針鼴鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鱷魚), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
【小題1】 What can we learn about the platypus according to the text?
| A．It has a lower body temperature than other mammals. |
| B．It only closes its eyes when underwater. |
| C．It’s the only poisonous mammal in the world. |
| D．It feeds its young on wild animal meat. |
| A．The crocodile. | B．The echidna. | C．The duck. | D．The dog. |
| A．its natural enemy | B．its appearance |
| C．its walking pose | D．its daily diet |
| A．is hunted for its meat | B．is in danger of extinction |
| C．is endangered by air pollution | D．is well-protected now |
| A．Platypus, a Trick? |
| B．Platypus, the Only Warm-Blooded Mammal |
| C．The Characteristics of Platypus |
| D．The Strange Mammal —Platypus。 |

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （紅外線）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （殺蟲劑）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害蟲）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.
【小題1】 Plants will emit an increased amount of heat when they are______________.
| A．sprayed with pesticides |
| B．facing an infrared scanner |
| C．in poor physical condition |
| D．exposed to excessive sun rays |
| A．estimate the damage to the crops |
| B．measure the size of the affected area |
| C．draw a color-coded map |
| D．locate the problem area |
| A．resorting to spot-spraying |
| B．consulting infrared scanning experts |
| C．transforming poisoned rain |
| D．detecting crop problems at an early stage |
| A．the lack of official support |
| B．its high cost |
| C．the lack of financial support |
| D．its failure to help increase production |
| A．the desire of farmers to improve the quality of their produce |

Did you get a flu shot this year？For the first time，the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine.
Vaccines battle diseases caused by bacteria and viruses.A weakened form of the germ (病菌) is introduced into the body.The body makes special substances called antibodies (抗體) to fight the germs.If the actual germs were to attack，the antibodies would fight.Because there are many kinds of flu viruses，scientists must create a new vaccine formula (處方) each year.Researchers must make a prediction.
It is like forecasting the weather.Sometimes they are right on，and sometimes they are off.But even when the vaccine does not closely match circulating flu types，it can make the illness less serious.
“The flu vaccine is not as effective as the polio (小兒麻痹癥) vaccine or the measles vaccine，” says Dr.William Schaffner of Vanderbilt University School of Medicine.“It’s not a great vaccine，but it is in fact quite a good vaccine.”
But a flu vaccine doesn’t work for everyone.There are certain people who should be careful about taking it，because the vaccine is produced in eggs.Those who are allergic (過敏的) to eggs should not take it.If you have a fever，you should wait until you recover.
Some people are afraid that they might get the flu from the flu shot.Scientists say that it is not possible，because the viruses in the flu shot are inactivated.But some minor side effects such as lowgrade fever and body ache could occur.If they do，they begin soon after the shot and usually last only one to two days.
Did you know？Smallpox was the first disease people tried to prevent by putting a virus into a healthy person.In 1796，English scientist Edward Jenner placed some infected material under a boy’s skin.
【小題1】The underlined word “vaccine” (in Para.1) refers to________.
| A．virus used for fighting against disease |
| B．a(chǎn)ntibody to fight the germs |
| C．formula to fight against disease |
| D．germ to be injected into the body |
| A．is as effective as the polio and the measles vaccines |
| B．is worse，compared with the polio and the measles vaccines |
| C．does help to make illness less serious |
| D．is quite good because it works for everyone |
| A．those who are not allergic to eggs can take the flu vaccine |
| B．not all the flu vaccines are effective for everyone |
| C．you should go to a doctor if you have a fever after taking the flu vaccine |
| D．it is possible that some people might get the flu from the flu shot |
| A．they’ll be allergic to eggs |
| B．their bodies will ache for 5 days |
| C．they probably have a low fever |
| D．they won’t catch a flu ever after |

Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留）into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. "The brain is not passive while you sleep. It's quite active. You can do quite a lot of things while you are asleep."
But the results don't mean that Spanish vocabulary tapes now have a place on the nightstand. L, Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster（垃圾車）in July knows, smells can cause a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale. But scent of fresh bread causes a long, deep inhale.、rzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers' noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or meat, was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.
【小題1】We can infer from the passage that
| A．while sleeping, we can learn whatever we want to learn |
| B．we will increase the size of inhale if we catch a pleasant smell |
| C．the knowledge we learned while sleeping will be forgotten in the next waken day |
| D．when walking by a bakery, the fresh bread will cause a nose-jerk reaction |
| A．One can’t acquire complicated knowledge during the sleeping hours. |
| B．Spanish vocabulary tapes now have a place on the nightstand |
| C．Researchers have tried to find evidence that the new words can be learned during sleep. |
| D．Complicated information can make its way into the brain during sleep |
| A．giving instructions | B．a(chǎn)nalyzing human brains |

Going Green
For career（職業(yè)） changers thinking about growth and advancement potential, forget the blue-collar and white-collar categories: Green is the way to go. According to Bracken Hendricks, a senior fellow at the Center for Global Progress, careers that promote environmental responsibility will become main stream within a decade. “The growth in green careers will be like the Internet boom, which not only created new jobs, but also had an influence on the overall economy（經(jīng)濟(jì)）,” he says.
The increasing environmental problems and need for eco-friendly products and services are creating a new job section of green-collar jobs. Many countries of the world have realized the importance and need for energy-saving products and services. It is expected that by 2025 about 25% of the jobs in developed countries will be of green-collar jobs. Doesn’t the data look promising for the future?
Green-collar jobs have become a bright career chances for all. And jobs will pop up at every income level, from environmental manager to gardener. For example, many countries including the United States have understood that fossil fuels have negative effect on the environment which can later become a serious danger to mankind. As a result, possibilities are being explored to find alternatives to satisfy demands in a better way. The increasing demand of newer resources（資源） has creating the need for experts and researchers who can find better ways to deal with the ongoing needs. In addition, in order to meet the increasing demands of environment-friendly equipment, both green product designer and educated and trained workers are needed. Management of environmental organizations also demands a large number of environmental managers.
Where can you find green-collar jobs? Internet is undoubtedly the best way to find information on almost any matter. Nowadays, different kinds of jobs are being posted online. Search through a couple of job websites to look for a bright future in energy conversion and recycling of waste management. Check regularly and find the right work for yourself. People who read newspapers can also find different kinds of green-collar jobs.
【小題1】Why does Bracken Hendricks mention the Internet Boom in Paragraph One?
| A．To explain the importance of technology. |
| B．To provide evidence of his recent research. |
| C．To indicate the bright future of green careers. |
| D．To inform us of the way of finding green-collar jobs. |
| A．Promoting services. |
| B．Training employees. |
| C．Consuming fossil fuels. |
| D．Developing new resources. |
| A．The requirements for green employees. |
| B．The development of the green industry. |

The airline lost your baggage. The hotel laundry(洗衣房) ruined your favorite shirt. The taxi driver overcharged you. When you're abroad, sometimes things go wrong. Now you can do something about it! Use these tips when you want to express an effective complaint in English.
No matter how unfair the situation, it's best to phrase your complaint politely. In English, you'll sound more polite if you use indirect language. Here are some examples:
“I'm sorry to bother you...” Starting a complaint like this puts the listener who may have heard many complaints that day at ease. Use this phrase if the situation isn't that serious. For example, "I'm sorry to bother you, but I wanted a baked potato, not fries."
“Can you help me with this?” Everyone would much rather be asked to do something than told! So try phrasing your complaint as a request for help: "Can you help me with this? My shirt came back from the laundry without buttons."
“I'm afraid there may be a misunderstanding.” This is a polite way of saying, "Your information is wrong. Please fix it now." You'll most likely use this phrase if you made reservations(預(yù)定) for a flight, hotel or restaurant, and when you arrive, it's not what you expected. For example, "I'm afraid there may be a misunderstanding. I requested a non-smoking room."
“I understand it's not your fault...” Often when you make a complaint, you deal with a person who was not directly responsible for the problem. But the problem isn't your fault, either! This phrase is helpful when you need swift action. Tell the person you're dealing with you understand they're not at fault and then directly state the problem: "I understand it's not your fault, but the airline promised they would deliver my baggage yesterday."
“Excuse me, but I understood that...” Using this phrase lets the person know you're well-informed and are suspicious they might be trying to take advantage of you. Don't say, "Hey! You're trying to cheat me!" Instead, start indirectly by stating what you know to be true: "I understood that the taxi ride to the airport was only 25 dollars." Then give them an opportunity to do the right thing.
【小題1】What’s the purpose of this passage?
| A．To give an introduction of life abroad. |
| B．To give suggestions on how to learn English. |
| C．To offer advice on giving complaints in English. |
| D．To offer guides to those who travel around the world. |
| A．state our complaints politely |
| B．go for the police immediately |
| C．use indirect language to hurt people |
| D．fight against the one who is responsible |
| A．Because the situation is never serious. |
| B．Because the listener may not speak English. |
| C．Because it can help solve the problem more easily. |
| D．Because we should be always in good manners abroad. |
| A．“Can you help me with this?” |
| B．“I understand it's not your fault.” |
| C．“Hey! You’re trying to cheat me!” |
| D．“I'm afraid there may be a misunderstanding.” |
