It is generally believed that we are getting cleaned when we step under a shower. We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about. A showerhead carries thousands of bacteria called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness (身體不舒服). When you turn on the water, the bacteria go from the showerhead onto and into your body.
This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. The scientists investigated bacteria in all kinds of human environment, including showers．Pace's team looked at 45 showerheads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.
But Pace said that they pose few threats to the health．Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your showerhead every few months.
However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.
Pace explained that he wanted to understand the natural microbial environments of public places. This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.
【小題1】From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because .
| A．it’s easy to get a cold when taking a bath |
| B．the showerhead carries many bacteria causing illness |
| C．we don’t get cleaned while showering |

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。 |

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）,” 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?

Barack Obama, Lady Gaga and Steve Jobs—what do they have in common? They are, of course, all Americans. And according to a survey by social networking site badoo. com, they all best illustrate(舉例說明) the word “cool”. 
But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.
Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy(哲學). “Cool” relates to ideas of grace(優(yōu)雅) under pressure.
“In Africa, ” he writes, “coolness is a positive quality which combines calmness, silence, and life.”
The modern idea of “cool” developed largely in the US in the period after World War II. “Post-war ‘cool’ was in part an expression of war-weariness (n. 厭戰(zhàn)情緒)
. . . it went against the strict social rules of the time,” write sociologists Dick Pountain and David Robins in Cool Rules:Anatomy of an Attitude.
But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies(欺凌弱小者). In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.
Today the focus of “cool” has changed to athletics (體育運動) stars. Often in movies about schools, students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.
But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.
“Call it the Harry Potterization of America—a time when being smart is the new cool,” writes journalist Joe Sunnen.
【小題1】Barack Obama, Lady Gaga and Steve Jobs are mentioned in the first paragraph to ________.
| A．introduce the topic | B．draw our attention |
| C．tell us what they have in common | D．tell us what is “cool” |

| C．didn’t observe rules and authorities |
| D．had all kinds of “bad” manners |
| A．do very well in their studies |
| B．a(chǎn)re very skilled at sports |
| C．a(chǎn)re good at chess and other thinking games. |
| D．have supernatural powers like Harry Potter |
| A．It is generally considered “cool” to be independent-minded and not to follow the crowd. |
| B．“Cool” was used as early as the 15th century. |
| C．Disobeying one’s parents and the authorities is considered “cool” among American young people nowadays. |
| D．Getting the first place in an exam can also be considered “cool”. |
| A．The origin of the word “cool”. |
| B．The kinds of people who are “cool”. |
| C．The changing meaning of the word “cool”. |

The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology（納米技術(shù)）, which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology（微電子技術(shù)）we use, such as the silicon chips of computers.
Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases.
The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this “absence of evidence” is not being taken as “evidence of absence”. In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods.
One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle（顆粒）size that should concern us, but its functionality. Take gold, for example, which is a famously inert (惰性) substance, and valuable because of it. It doesn’t rust or corrode because it doesn’t interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface area of many pea-sized balls with the same weight of the single basketball. The pea-sized balls have a surface area many hundreds, indeed thousands of times bigger than the basketball, and this allows them to interact more easily with the environment. It is this increased interactivity that changes their functionality—and makes them potentially more dangerous to health or the environment.
【小題1】Why does the writer mention microtechnology in the first paragraph?
| A．to introduce the topic of nanotechnology |

| C．to help us know more about microtechnology |
| D．to compare microtechnology with nanotechnology |

While students in Hainan are quite used to clear skies, Beijing teenagers are not so lucky. As another warm winter approaches, the city can expect the normal clouds of smoke caused by air pollution.
But things may start to improve soon. The government is co-operating with a US-based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel engines(柴油機)by 40 percent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them.
“We encourage the development of public transports. But at the same time we need to reduce pollution from them, ”said an official.
Efforts are being made to improve the capital’s environment with tighter controls on emissions(排放). Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed.
Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index(指數(shù))gave just 100 days as good.
“I am glad to see an improvement, ”said a senior 1 boy living in the northwest of Beijing. “Compared to other places, the air quality of Beijing is still worrying though. I hate pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn’t see a car only metres away from me in fog. ”
In early October, the skies were covered by such a thick fog that a display show by the visiting French Air Force was called off.
Rapid development, industry, traffic fumes and sandstorms from the desert all contribute to the city’s bad air.
【小題1】 The passage is mainly about .
| A．a(chǎn) programme aiming at improving Beijing’s air quality |
| B．progress made in Beijing’s air quality |
| C．Beijing’s air pollution |
| D．the differences between Hainan and Beijing |
| A．Clean fuel technology will be used in public transports. |
| B．Some factories have been asked to cut production. |
| C．Some construction sites have been told to be closed. |
| D．A display show of airplanes has been called off. |
| A．far more still needs to be done |
| B．nothing else needs to be done |
| C．a(chǎn)ll traffic has to be closed |
| D．the development of the city has to be slowed down |
| A．Beijing’s air quality is getting worse and worse. |
| B．Rapid development, industry, traffic fumes and sandstorms are all the causes of bad air quality. |
| C．People see clouds of smoke in the sky in the winter of Beijing. |
| D．The government is making efforts to stop air pollution. |

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.” |

If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(過錯). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受責備), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
【小題1】The main reason for one’s poor memory is that _______.
| A．his memory is not often used |
| B．he does not use his name or legs for some time |
| C．his father or mother may have a poor memory |
| D．he can’t read or write |
| A．you can’t use them any more |
| B．they will become stronger |
| C．they will become neither stronger nor weaker |
| D．they become weak and won’t become strong until you use them again |

How can we measure animals’ emotions? A new study of animal’s emotions suggests that, as in humans, emotions can tell animals about how dangerous their world is, and guide the choices that they make. The article of the study by Bristol University’s professor Mike Mendl was published online.
An animal living in an environment where it is often threatened by predators(捕食者）will develop a negative emotion or “mood”, such as anxiety. However, one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state.
The researchers say that these emotional states not only show the animal’s experiences, but also help it decide how to make choices, especially in unclear situations. This could have good or bad results. An animal in a negative mood state will make a safety-first with a “pessimistic” response to an unclear event. For example, it considers a noise in the grass as a signal of the predator. At the same time, an animal in a positive mood state will benefit from a more “optimistic” response. It considers the noise as a signal of prey(獵物）.
Professor Mike Mendl, head of the Animal Welfare and Behavior Research Group at Bristol University’s School of Clinical Veterinary Science said, “ We can use “optimistic” or “pessimistic”decision-making as a symbol of an animal’s emotional state. Recent studies by our group and others suggest that this is a meritorious new approach to studying a variety of animal species.”
“Public interest in animal welfare remains high, with widespread concern about the way in which animals are treated, used and included in society. To understand how animals should be treated, we need to better understand their emotional lives,” Mike Mendl said. The researchers believe Mike Mendl’s study can help them to better understand and assess an animal’s emotions.
【小題1】When an animal is in a negative mood state, _______.
| A．its response to an unclear event is pessimistic |
| B．it will pay little attention to an unclear event |
| C．it is easy for it to make right decisions |
| D．it has more opportunities to get food |
| A．valuable | B．useless | C．fashionable | D．hopeless |
| A．the animals with positive emotions live longer |
| B．there is no way to assess an animal’s emotions |
| C．few people care about animal welfare nowadays |
| D．the environment can influence animal’s emotions |
| A．tell people to build more protected areas for animals |
| B．explain animals should be regarded as people’s friends |
| C．raise people’s interest in studying animals |
| D．make people know how to treat animals properly |
| A．Different kinds of Animals’ Emotions |
| B．Emotions Helps Animals to Make Choice |
| C．The Living Environment of Wild Animals |
