Climate change could affect food supplies, water resources, human health and homes.
If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2°C and 6°C by 2100. This doesn’t sound much, but a 5°C change is the difference between the current warm period and an ice age.
Global warming leads to other changes in the climate: melting ice, more evaporation(蒸發(fā)), changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise.
These changes could affect crop growth as drought, increased evaporation and shrinking glaciers（冰川）disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1–2 °C is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 °C or more could threaten global food resources, as all regions are likely to experience negative impacts overall.
Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera（霍亂）becoming more widespread.
Climate change could lead to a variety of health impacts – both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as hypothermia, overall a warming world is likely to have negative effects on human health.
Scientists also expect damage to homes and buildings from more intense hurricanes, heavier rainfall and rising sea levels. Climate change is likely to affect infrastructure by increasing the risk of both coastal and inland flooding around the world, owing to a combination of heavier rainfall, rising sea levels and increased storm damage. Homes and buildings could also be affected by the thawing of frozen ground and greater risk of forest fires.
The consequences of climate change will have an impact on people around the world.

Exploit your parking space
An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement for free on Letpark or Atmyhousepark.
Rent a room
Spare room? Not only will a lodger(房客) earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
Won’t want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your space.
Live on set
Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free — but you will be charged if your home gets picked.
Use your roof
You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment(around￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.
【小題1】If you earn ￡5000 from renting a room in one year, the tax you need to pay will be based on ______.
| A．￡800 | B．￡500 | C．￡4500 | D．5000 |
| A．On Letpark. | B．On Roomspare. |
| C．On Grashpadder. | D．On Roommateeasy. |
| A．sign an agreement with the government |
| B．pay around ￡14,000 for the equipment |
| C．sell the roof to some energy companies |
| D．keep the roof unchanged for within 25 years |

Although considered an excellent exercise, jumping rope has never received widespread acceptance because of two reasons. First, most people recognize jumping rope as an excellent form of cardiovascular(心血管的)exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes in order to achieve a beneficial physical effect. Second, many regard it as somewhat boring and overly repetitive(重復(fù)乏味的)—not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun as long as you find a proper way to practise it. Instead of doing the usual two-foot bounce(跳)over and over again, players good at rope-jumping often change their pattern every 10 or 20 jumps: a single bounce, a double-bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Nowadays researchers are discovering that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres(半球)to perform equally to each other.
In short, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
【小題1】 One reason that can explain why rope-jumping has not spread widely is that
.
| A．it benefits the cardiovascular system |
| B．it is too difficult for people to learn to jump |
| C．it is believed to be boring and repetitive |
| D．it requires little equipment, time and space |
| A．there is only one proper way to follow |
| B．the usual way should not be used again |
| C．the easiest way is always the best one |
| D．there are different kinds of ways to follow |
| A．only prepares the brain for learning |
| B．is suitable for students only |
| C．helps both brain hemispheres work together |
| D．can be dangerous for old people |
| A．He is strongly against it. |
| B．He is for it. |
| C．The passage doesn’t mention it. |
| D．He knows little about it. |

Dr. Sylvia Earle wants you to stop eating fish. It's not because fish are endangered, though wild fish stocks in many oceans are very low. It's not because they're bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they're smart.
"Fish are sensitive, they have personalities," says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. "I would never eat anyone I know personally."
There's a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether.
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. "While it may seem conspicuous that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables," says Dr. Lynne Sneddon. "Really, it's kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?"
Fishermen and (fried) fish lovers are skeptical. "I've never seen a smart fish," says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. "If they were very smart, they wouldn't get caught."
"For years, everyone's been telling us to eat fish because it's so good for us," says another diner. "Now I've got to feel guilty while I'm eating my fish? What are they going to think of next? Don't eat salad because cucumbers have feelings?"
【小題1】According to Dr. Sylvia Earle, he would stop eating fish as a result of the following reasons EXCEPT ___________ .
| A．Fish are sensitive and have personalities |
| B．He knows fish very well |
| C．Fish are dangerous to eat because the water is polluted |
| D．Fish are clever |
| A．opposed | B．optimistic | C．indifferent | D．supportive |
| A．obvious | B．easy | C．impossible | D．necessary |
| A．Human beings should stop eating fish |
| B．We would feel guilty if we continued eating fish |
| C．People eat fish because fish are delicious |
| D．Cucumber is a kind of vegetable or fruit |
| A．To advise people to stop eating fish. |
| B．To introduce a topic of whether people should eat fish. |
| C．To advise people not to stop eating fish. |
| D．To tell us that fish will feel pain when caught and transported. |

Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgment(判斷) to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day’s work.
Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛).
Ability(能力) to sleep is largely a habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(藥) should never be taken except when suggested by a doctor.
【小題1】We know from the passage is enough for the health of a pupil.
| A．equal or more than eight hours | B．seven hours or so |
| C．Eight hours or so | D．Less than eight hours |
| A．forming the habit of taking sleep-producing drug. |

A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air.
China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both particulate pollution of the air and life expectancy in the two regions.
While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the researchers, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of 一Technology. "This study provides a unique setting to answer the life expectancy question because the(heating) policy dramatically changes pollution concentrations（含量），，，Greenstone said in an email. "Further, due to the low rates of migration in China in this period, we can know people's exposure over long time periods," he said.
The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Riv饑which divides China into north and south. It was in effect for much of the 1950-198,0 period of central planning, and, though discontinued after 1980, it has left a legacy（遺留） in the north of heavy coal burning, which releases particulate pollutants into the air that can harm human health. Researchers found no other government policies that treated China's north differently from the south.
The researchers collected data for 90 cities, from 1981 to 2000, on the annual daily average concentration of total suspended（懸浮的）particulates. In China, those are considered to be particulates that are 100 micrometers or less in diameter, sent out from sources including power stations, construction sites and vehicles. Among them, PM2.5 is of especially great health concern because it can go deep into the lungs.
The researchers estimated the impact on life expectancies using death data from 1991-2000． They found that in the north, the concentration of particulates was 184 micrograms per cubic meter一or 55 percent higher than in the south, and life expectancies were 5.5 years lower on average across all age ranges.
【小題1】The main idea of this passage is that＿·
| A．research in China finds air pollution shortened life expectancy |
| B．the government provided free coal for heating in North China |
| C．coal burning causes bad air quality across China |
| D．a(chǎn) new study finds different particulates in South China |
| A．power stations | B．construction sites |
| C．the free heating policy | D．gases from vehicles |
| A．coal is no longer used for heating in North China |
| B．a(chǎn)ir quality was comparatively better in South China |
| C．southerners burned coals for heating in the 1980s |
| D．people preferred to live in South China after 1980 |
| A．dirty clouds | B．particular smoke |

Eat nuts, live longer. Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective.
Researcher Ying Bao is with the Department of Medicine at Brigham and Women’s Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses’ Health Study, which tracks the well-being of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study.
Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades.
“What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying.”
Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams.
Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart.
Bao says researchers are planning studies to find out how nuts are beneficial to human health.
The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation.
【小題1】People who often eat nuts ________.
| A．a(chǎn)re more likely to live longer than people who often eat fruits |
| B．don’t need to go to hospital |
| C．may live longer than people who don’t eat nuts |
| D．don’t have to do sports |
| A．illness | B．health | C．diet | D．habit |

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （oppositely） affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不動的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?
【小題1】Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
| A．beauty should be overweight |
| B．a(chǎn) fat man is usually a cheerful character |
| C．fatness was considered something good at one time |
| D．fatness leads to an increased risk of disease |
| A．go on a diet | B．do regular physical activity |
| C．give up smoking | D．go to the gym |
| A．people who help you do exercise | B．places where you can do exercise |
| C．a(chǎn) kind of shoes | D．a(chǎn) form of vehicles |
| A．a(chǎn)n increased risk of diseases | B．a(chǎn) happier life |
| C．a(chǎn) cheerful character | D．a(chǎn) beauty |
| A．how to keep fit and avoid fatness. | B．increased risks for overweight people. |
| C．the dangers of exercise in the gym. | D．the benefit of a balanced diet. |
