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.

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.
【小題1】With global temperature increased by 1–2 °C, _______.

A．crops yields could be increased in tropical regions
B．food production could rise throughout the world
C．chances are that food resources would be threatened overall
D．mid-latitude areas are likely to experience positive impacts
【小題2】The underlined word “hypothermia” in Paragraph 6 possibly means a serious medical condition caused by_______.
A．lower temperature than normal
B．higher temperature than normal
C．more cases of malnutrition
D．cases of waterborne diseases
【小題3】According to the passage, climate change has both positive and negative effects on ______.
A．food supplies and buildings
B．freshwater resources and homes
C．human health and food supplies
D．human health and homes
【小題4】The passage is mainly meant to tell us _______.
A．how global warming leads to changes in the climate
B．how climate change affects people worldwide
C．why climate change affects our crop growth
D．why climate change contributes to all bad results

The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health. There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine(咖啡堿)in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much. Caffeine makes your heart beat fast. Because of this, the International Olympic Committee(IOC) has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

Is crying good therapy? Experts say yes. Having a good weep at the weekend is becoming more popular among office workers in China.
“I need to cry to let my feeling out,” said 22-year-old Guo Meng, a smart-looking young woman. “I remember one day when I got home I felt so down but I had no one to talk to, so I just curled up(蜷縮) with my teddy bear and cried myself to sleep,” Guo said. The next day, she said, she felt much better and life seemed not so bad after all.
Because crying is taken as a sign of weakness, people make a great show of being strong and not displaying emotion. Psychologists and medical practitioners agree that crying is beneficial for mental health but people still regard it as a sign of failure and bottle up their feelings. A famous Chinese author once said to cry is normal, and even brave. Those who display their emotions can deal with their troubles bravely after the tears dry, while those who soldier on let problems fester（惡化）.
In the Chaoyang district of Beijing, there is a special place for people to cry their sadness out. It is called “Cry Bar”. On the door of each of its “cry rooms” there is a saying encouraging people to let the tears flow freely.
“Crying is a kind of therapy, but it needs some direction,” said Milulu, a psychologist.
“People should realize the point of crying is to relieve pressure, but some of the young people who come to the Cry Bar simply sit and weep. The purpose of crying is to make it easier to improve your life after the tears dry, not to get lost in bad memories.”
Crying is only one way of relieving pressure, and we need to face problems squarely and solve them once the tears have dried, said Mululu.
【小題1】Crying _____ made Guo Meng feel better.

A．with some friend B．a(chǎn)ll the night with a toy
C．during her sleep D．in bed before sleep
【小題2】According to the third paragraph, people usually make great efforts to_____.
A．get rid of their sadness B．bottle up their feelings
C．a(chǎn)ct on psychologists’ advice D．face their troubles bravely
【小題3】What should the customers do at the Cry Bar?
A．Think of every sad experience they’ve had and cry
B．Keep crying as loudly as long as possible.
C．Satisfy any desire to cry and weep until it is gone.
D．Hold back their tears until they can’t help but cry.
【小題4】From the text, we can learn that crying ____.
A．is to relieve pressure B．must help to solve problems
C．means facing problems squarely D．can’t weaken sad feelings.

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour (跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what about making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.
Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."
Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.
【小題1】Parkour has become popular throughout the world because of________.

A．its founder, David BelleB．the film, Casino Royale
