Average age is rising around the world——a demographic （人口统计）change that may pose a significant challenge to efforts to slow down climate change.
Hossein Estiri at Harvard University and Emilio Zagheni of the Max Planck Institute for Demographic Research, Germany, have found that energy use increases as we get older, and not just because we tend to get wealthier. An ageing population could mean a greater proportion of society with higher energy use, their study suggests.
They combined two decades, worth of data from thousands of US households and used this to build a model to reveal how energy use varied across 17 age groups between 1987 and 2009. They found that, on average, children's energy consumption （肖耗）climbs as they grow up, before dipping slightly when they leave home. Consumption then rises again when people hit their 30s, before briefly dropping after 55, and then beginning to climb again. The study involved factors such as income, local climate and the age, type and size of a person's home. The increase in energy use at various points in our lifespan （寿命）seems to be the result of life style and how our needs change as we age.
Why does demand grow so much in our 30s? “We need more of everything. More space, a bigger TV two fridges," says Estiri. The study found that, in warmer parts of the US, energy use increases in people over the age of 65—probably as a result of increased use of air conditioning, This suggests that there is a feedback effect between climate change and an ageing population that will only make matters worse.
Heat waves have become more common in the US in recent years and are expected to become more frequent due to global warming. More older people using more electrical energy to keep cool as temperatures rise could add to emissions （排放），and thus drive more warming until our energy supply becomes entirely fossil fuel-free.
“This confluence （汇集）of population, ageing and climate change on energy demand is really important to start thin king about," says Estiri. Benjamin Sovacool at the University of Sussex, UK, says the work shows the importance of demographics when it comes to cutting carbon emissions. Most modelling of climate change mitigation （减缓气候变化的模型） assumes people's energy consumption either stays the same or only changes by a small amount over time.
"This study directly challenges that entire body of research by forcing it to fight with the temporality and complexity of the consumption of energy, says Sovacool.
Catherine Mitchell at the University of Exeter, UK, says the research could have an important influence on policy makers. "What the paper says is that there is a lot of work about how buildings use energy, but probably not enough about how the people in them use energy," she says.
1.By saying “not just because we tend to get wealthier" in Paragraph 2, the writer probably means that .
A.poor people can't bring down the high demand for energy
B.a comfortable life is not the main cause of in creased energy use
C.there are some other reasons leading to the increase in energy consumption
D.people being wealthy or not has nothing to do with the rise of energy consumption
2.What does the author intend to tell us in Paragraph 3?
A.Children consumes more energy when they leave home.
B.Energy consumption drops briefly before people hit 55.
C.The researchers built a model to study the data from US households.
D.Energy consumption varies with the change of lifestyle and demand at different ages.
3.Which of the following statements is Hossein Estiri most likely to support?
A.Energy will stop increasing when people get older.
B.His research could inspire policymakers to change current polices.
C.Various factors influencing energy consumption should be considered.
D.Old people should use fossil fuel-free rather than electrical energy to keep cool.
4.What is the shortcoming of most modeling of climate change mitigation?
A.It is expensive and difficult to promote.
B.It overestimates the household energy consumption.
C.It did not take climate change adaptation into account.
D.It regards energy consumption as stable or as only slightly changing.
5.What can we learn from the last paragraph?
A.More emphasis should be put on people's energy use.
B.The government can't do much without the support of the study.
C.It is the buildings, not the people in side, that consume the majority of the energy.

My family moved to St. Paul, Minnesota last year, where the average winter temperature is around 10 degrees Fahrenheit. Once summer ended, everyone went inside to play ice hockey. I’d been on the ice only a couple of times when I was much younger. When I’d fallen and broken my wrist during my second lesson, I’d decided never to put on ice skates again.
Ben, the friend I made in the new city, volunteered to teach me to skate. Even though he was very patient, I was so embarrassed by my clumsiness that I began to make up excuses for not skating.
One day I discovered a faster route home. It took me past a large frozen pond. I noticed a woman teaching a young girl to skate. The girl was attempting to jump and spin in the air.
Over and over, she pushed off the ground with the toe of her skate. And over and over, she landed hard on the ice.
After I had been watching the girl practice for about a week, one afternoon she suddenly lifted off the ground, spun in the air, and landed on her feet!
The next day I bought myself some brand new skates. Every day on the way home I stopped at the pond and wobbled onto the ice, right next to the girl who had landed her jump. As she perfected her twists and tricks, I taught myself to glide and turn. It was hard being a beginner, and when I fell I had to fight the urge to simply give up. Instead, every time I went down, I just picked myself up and started over again. Soon I was able to keep my balance and skate more confidently. In just a few weeks, I was actually ready to practice the speed skating, fast stops, and quick turns needed for ice hockey. When I was finally ready to show Ben my newfound skating ability, he told me I should join the local hockey league. I tried out and was chosen for a team. By the end of the season, I was part of a winning team.
1.What can we learn about the author?

B.He preferred ice hockey to skating.
C.He had once given up learning skating.

2.Why did the author mention the girl on the pond?
A.To prove the girl was skillful.
B.To suggest the girl inspired him.
C.To show the girl was a quick learner.
D.To explain how he came across the girl.
3.According to the last paragraph, the author’s training was________.
A.easy and basic B.hard but rewarding
C.boring and tiring D.strict but interesting
4.What does the story mainly tell us?

There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries.
Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, “If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families.”
East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market.
Mr. Barrow says, “It needs the government to make some arrangements such as providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, they are asking for food from overseas.”
Economists say that imports reduce local food prices, decrease productivity(生产效率) and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.
1.What is the best title for this passage?
A. Kenya Imports Food from Abroad
B. A World Food Program in Rome.
C. The Poor Suffer from High Food Prices.
D. A Report Published by Three UN Agencies.
2.What do we know about Kenya from the passage?
A. The people in central Kenya are suffering from hunger.
B. At least three and a half million Kenyans lack food.
C. The Kenyan government wants to improve road conditions.
D. People in northern Kenya refuse to ask for food from overseas.
3.What does “they” in the fourth paragraph refer to?
A. The people of northern Kenya.
B. Government officials.
C. The farmers of central Kenya.
D. Kenyan economists.
4.Which of the following statements is TRUE, according to this passage?
A. Gregory Barrow suggests that Kenya make good use of overseas food.
B. People in northern Kenya are suffering the drought less than the central.
C. Economists believe importing food from abroad may cause problems.
D. Kenyan government hopes to buy the native crops at higher prices.

Around the world there is an increase in the demand for reforestation. This is because the consumption of the forests has affected not only the animals living in the area but also the people. And reforestation is about the rebuilding of the forests that have been severely destroyed. It can offer a lot of benefits when the recreation is successful.
1.This includes collecting seedlings(幼苗) that are native in the area to make sure that there is a natural reconstruction of the area. Some additional trees which are not native in the area also need to be planted.
2.The importance of having multiple species of trees is considered to make sure that the needs of other species that will live and grow in the area are met.
Destroying a forest is easy but rebuilding it is really hard.
3.The plan must include accurate spacing on plants and trees. This is to ensure that they won’t cover each other while they grow.
4.The forest greatly helps in the reduction of the air pollution. Trees are responsible for the production of oxygen and absorption of carbon dioxide.
5.It is there for a reason just like everyone else on this planet.
There cannot be a better way to restore the balance of nature than to increase the forest area. We must remember that the forest is a natural habitat of wide variety of animals and plants. In this manner, there is no substitute for reforestation.
A. And global warming will speed up the destruction of forests.
B. Keep in mind that you can’t just plant the seedlings anywhere.
C. Recreations won’t work until all these details have been considered.
D. So a good plan is needed to make the reforestation a successful one.
