Cutting global warming pollution would not only make the planet healthier, it would make people healthier too, new research suggests.
Cutting carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies released Wednesday and published in a special issue of The Lancet British medical journal.
“Relying on fossil fuels leads to unhealthy lifestyles, increasing our chances for getting sick and in some cases takes years from our lives,” US Health and Human Services Secretary Kathleen Sebelius said in a telecast (電視廣播) briefing from her home state of Kansas. “As greenhouse gas emissions go down, so do deaths from cardiovascular (心血管的) and respiratory diseases (呼吸疾病). This is not a small effect.”
Instead of looking at the health ills caused by future global warming, as past studies have done, this research looks at the immediate benefits of doing something about the problem, said Linda Birnbaum, director of the US National Institute of Environmental Health Sciences.
Some possible benefits seemed highly speculative (投機(jī)的,推測的), the researchers conceded (承認(rèn),給予), based on people driving less and walking and cycling more. Other proposals studied were more concrete and achievable, such as reducing cook stoves that burn dung (糞便), charcoal and other polluting fuels in the developing world.
And cutting carbon dioxide emissions also makes the air cleaner, reducing lung damage for millions of people, doctors said.
“Here are ways you can attack major health problems at the same time as dealing with climate change," said lead author Dr. Paul Wilkinson, an environmental epidemiologist at the London School of Hygiene and Tropical Medicine.
Wilkinson said the individual studies came up with numbers of premature deaths prevented or extra years of life added for certain places.
For example, switching to low-polluting cars in London and Delhi, India, would save 160 lost years of life in London and nearly 1,700 in Delhi for every million residents, one study found. But if people also drove less and walked or biked more, those extra saved years would soar (高聳,高漲) to more than 7,300 years in London and 12,500 years in Delhi because of less heart disease.
小題1:What does the passage mainly about?
A.How can people live longer.
B.Cutting carbon dioxide emissions saves life.
C.Global warming threatens people’s lives
D.People should stop relying on fossil fuels
小題2:The new research differs from past studies in that ________.
A.it focuses on the immediate benefits of cutting carbon dioxide emissions
B.it studies the bad effects arising from future global warming
C.it is believed by most people
D.it mainly targets at developing countries
小題3:According to Kathleen Sebelius ________.
A.sometimes it takes years to see the bad effects caused by consuming fossil fuels
B.without greenhouse gas emissions, people would not die of cardiovascular and respiratory diseases
C.the main reason why people get sick is that they rely on fossil fuels
D.death from cardiovascular and respiratory diseases are closely related to greenhouse gas emissions
小題4:It can be inferred from the passage that ________.
A.London and Delhi have already benefited from reducing greenhouse gas emissions
B.switching to low-polluting cars would save 160 lives in London every year
C.walking and biking instead of driving will reduce the chance of heart disease
D.a(chǎn)ttacking health problems and dealing with climate change are contradictory

When my brother and I were young, my mom would take us on Transportation Days.
It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the train, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home—our first car ride of the day.
The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a  failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.
Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light­rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.
On Transportation Days, we might stop for lunch on Chestrut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river?
I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me.
小題1: According to the writer, what was the greatest benefit of her Transportation Days?
A.Building confidence in herself.
B.Reducing her use of private cars.
C.Developing her sense of direction.
D.Giving her knowledge about vehicles.
小題2: The underlined word “paralyzed”(in Para.5) is closest in meaning to “________”.
A.displayedB.justifiedC.ignoredD.ruined
小題3: Which means of transportation does the writer probably disapprove of?
A.Airplane.B.Subway.C.Train.D.Car.

In general, people talk about two groups of colours warm colours and cool colours. Researchers in psychology think that there are also two groups of people people who prefer warm colours and people who prefer cool colours.
The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colours are green, blue and violet. These colours, unlike warm colours , are relaxing. Where there are cool colours, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colours than in a room with cool colours. He suggests that a warm colour, such as red or orange is a good colour for a living room or restaurant. People who are relaxing or eating do not want time to pass quickly. Cool colours are better for offices or factories if the people who are working there want time to pass quickly.
Researchers do not know why people think some colours are warm and other colours are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue and violet are cool. Perhaps warm colours remind people of warm days and the cool colours remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.
小題1:Which of the following colours belong to cool colours?
A.Yellow, green.B.Blue, violet.
C.Black, blue.D.Brown, white.
小題2:Which of the following statements is not true?
A.Sociable people like warm colours.
B.Warm colours can make people excited.
C.People who like to be with others don’t like red.
D.Where there are warm colours, people want to be active.
小題3:Which is the right colour for different rooms?
A.Red or orange for offices.
B.Orange for dining-rooms.
C.Blue for bedrooms.
D.Red for studies.
小題4:What is the main idea of the last paragraph?
A.It shows the reason why people think some colours are warm and others are cool.
B.Warm colours remind people of warm days.
C.Cool colours remind people of cool days.
D.People have an agreeable opinion of warm colours and cool colours.

A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.
When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.
At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.
“In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.
“If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.
“People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.
小題1:The author wrote the passage mainly to tell us _____.
A.the importance of blankets
B.how to choose the perfect blanket
C.different materials used to make blankets
D.the history and usage of blankets
小題2:The underlined word “rouse” in Paragraph 2 is the closest in meaning to “______”.
A.wake upB.take upC.make upD.pick up
小題3:What do we know from the passage?
A.Body temperature rises when we fall asleep
B.The perfect sleep temperature should be above 70 degrees F.
C.Weighted blankets should be at least 30 pounds.
D.People are advised to use their own blankets.

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.

Can we give a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot.
1. Protect wildlife habitat.
Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the only habitats that are left untouched by habitat destruction.
2. Reduce the threat of invasive (入侵的) species.
The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (資源) and habitat. They can even prey on native species directly, forcing native species towards extinction.
3. Place decals (貼花紙) on windows.
It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.
4. Slow down when driving.
Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障礙) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.
小題1: What would be the best title for this passage?
A.How animals go to extinction
B.The importance of protecting wildlife
C.What to do to help save wildlife
D.How to protect wildlife habitat
小題2:By writing the underlined sentence, the writer means that _____.
A.more parks and reserves should be built
B.we should have more habitats free of destruction
C.there is a need for improvement in parks and re-serves
D.parks and reserves are good examples of protecting wildlife
小題3:People are advised to put decals on windows to _____.
A.decorate the houses and beautify the environment
B.protect the windows from birds hitting
C.a(chǎn)ttract more birds to make homes nearby
D.a(chǎn)void birds hitting the windows by mistake

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
C.Strange Species
D.The Smallest Backbone Animal
小題2:65.Where does the smallest backbone animal live?
A.It lives in highly acidic rainwater.
B.The species lives in the acidic waters of dark tea-coloured swamps.
C.It was put in the Natural History Museum in London.
D.Its habitat disappears completely.
小題3:66.According to the passage, the forest fires in 1997 have led to the fact that______.
A.many places where these animals lived have been damaged
B.the population of the specieshas increased
C.there are many animals in the acidic peat swamps today
D.a(chǎn)griculture doesn’t affect the living space of these animals
小題4:67.Dr Britz’s words imply______.
A.the habitat will be more after a period of time
B.many peat swamps that they surveyed have already survived
C.he wants to find more miniature fishes before their habitat disappears
D.he wants to have further research

Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, “the father of medicine”, was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad.
Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname(綽號(hào))for the vegetable, in fact, was “poor man’s bread”, because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with it.
Watercress is a member of the mustard(芥菜) family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems(莖)contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them.
The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is  best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach—another dark green vegetable—in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food.
小題1:From paragraph 1, we can learn that________.
A.watercress is usually grown in wet areas
B.the ancient Greeks only used watercress for medicine
C.watercress is the most ancient vegetable known to man
D.the Romans rubbed watercress on their heads to cure baldness
小題2:The underlined word “it” in paragraph 2 refers to “_________”.
A.butterB.watercressC.breakfastD.bread
小題3:Which of the following is TRUE about watercress?
A.It belongs to the same family as spinach.
B.It contains mustard oils only in leaves.
C.It can help guard against cancer.
D.It is rich in vitamins C and B.
小題4:Compared with older watercress, young watercress      .
A.has lighter green leaves
B.contains more minerals
C.is better for medical use
D.is more suitable for eating raw
小題5:What would be the best title for the text?
A.The history of watercressB.watrcress, a medicinal plant

Scientists Alan M.Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物學(xué))testing.Improvements in cell and tissue culture technologies,for example,allow a growing number of tests to be performed on human cells alone.Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals.
Since the late 1990s,Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants (好戰(zhàn)分子).At a hearing,a Senate.committee listened to testimony(證詞) against Huntingdon employees and financial institutions providing services to the company.One experimentation witness at the hearing insisted that any means necessary were justified(辯護(hù)) to spare animals’ lives;he has previously accepted the idea of murder to that end.
Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically(倫理道德地)preferable to experimenting on humans or giving up cures that could save human lives.But for the sake of people and animals alike,the development and acceptance of animal substitutes deserve enthusiastic support.
In some instances, substitutes are already thought as good or better than animals,but supervising agencies(監(jiān)督機(jī)構(gòu))have yet to catch up.In both the European Union and the U.S.,scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals.Thus,animal-loving Americans might turn to persuading the EPA and the FDA to speed validation(確認(rèn))of new methods so that they can be more widely employed.And animal advocates(保護(hù)者) who want to influence business could consider investing in the small biotech’s and large pharmaceutical(藥品的) companies that are working to develop alternatives to animals in research.
小題1:_____ plays a leading role in replacing the use of animals in testing.
A.Huntingdon Life SciencesB.Improvement in technologies
C.Animal-fights militantsD.Scientists Alan and Thomas
小題2:Accordingly, the animal-rights militants hold the view that_____.
A.a(chǎn)nimals shouldn’t be used in toxicology testing
B.a(chǎn)nimals should enjoy equal rights with human beings
C.a(chǎn)nimals should live wildly and freely
D.we should protect animals from being killed casually
小題3:From the passage,we can find _____.
A.the use of animals in testing has been stopped abruptly
B.a(chǎn)nimal substitutes are not preferable
C.supervising standards contribute to the continued use of animals in testing
D.only Huntingdon Life Sciences is accused
小題4:What’s the main idea of the passage?
A.Saving animals and people.
B.The new trend in toxicology testing
C.The use of animals in testing is against human nature
D.New technology changes the fate of animals
小題5:The writer’s attitude towards replacing the use of animals in toxicology is____.
A.a(chǎn)rbitrary(武斷的,隨意的)B.pessimistic
