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.

D.Policymakers have been working on how to cut down people's energy use.

6.Which column may the article be taken from on the Internet?

A.Health. B.Environment.

C.Human. D.Technology.

Nearly 790 million people around the world do not get enough to eat, most of 1. live in developing countries.

A group of researchers in California may have found a way 2.(help) feed the hungry people. Stephen Mayfield, a professor at the University of California, studies on algae(藻类). He says, “The world, in fact, is not short of calories. 3. it is short of is proteins(蛋白质) and essential fatty acids(脂肪酸). Algae are 4.(natural) very high in proteins and fatty acids and those are sort of the two things that the world really needs.”

Mayfield and his team have made algae 5. different kinds of food. Not only is the algae food rich in protein and fatty acids, but it also 6.(taste) pretty good.

And growing algae uses 7.(little) land than other kinds of protein. Mayfield’s big idea is that algae farms could one day replace the huge amounts of land 8.(use) by farmers to produce protein from cattle or soybeans.

Today, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板）.Riders moved it by pushing their feet against the ground.

In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.

In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a velocipede，but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the velocipede was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.

Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient，and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy，and ridden mostly for entertainment.

It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893，the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson_; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.

1.This passage was most likely written in order to _____.

A．compare bicycles used for different purposes

B．describe the problems early bicycle makers experienced

C．persuade readers to use bicycles for transportation

D．tell readers about the early history of the bicycle

2.Macmillan covered the wheels of his bicycle with iron to _____

A．add weight to the bicycle

B．make the bicycle easier to ride

C．allow the wheels to last longer

D．let the bicycle be more comfortable

3.Which of the following bicycle types was invented by James Starley?

4.Which of the following statements is true according to the passage?

A．Two hundred years ago，bicycles did not exist.

B．The first bicycle could be ridden at a very quick pace.

C．The Michaux brothers called their bicycle a “bone shaker”.

D．Macmillan’s machine had wheels with rubber tires.

5.The information about bicycles in this passage is arranged according to _____.

A．importance        B．time              C．place             D．Interest
