The Green Microgym in Portland，Oregon has all the usual stuff you'd expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕获）the energy you create while riding, converts（转换）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流电流）into any standard wall outlet-for this reason，the product line's name is Plug Out-and the energy created is used before the building draws power from the grid（电网）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．Members of the Green Microgym earn gift certificates for_______．
| A．using the man-powered exercise equipment |
| B．saving electricity for local businesses |
| C．producing green electricity to power their phones |
| D．paying higher membership fees |
The spin bikes made by Resource Fitness are different from those by Green Revolution in that_______.
| A．they are easier to ride |
| B．they are more expensive |
| C．they don't have wires connected |
| D．they can not store extra electricity |
What might prevent the green exercise equipment from getting more popular？
| A．People's unwillingness to go green． |
| B．The high cost of making it. |
| C．Safety problems concerning electricity. |
| D．Lack of certificates． |
The underlined words“make the switch”in the last paragraph most probably mean_____.
| A．change to a different gym |
| B．use green exercise equipment |
| C．switch on the spin bikes |
| D．add a battery to the machine |
The State Council declared Wednesday it would restart China's nuclear power program, ending the hiatus（中断）in nuclear construction since Japan's Fukushima nuclear disaster last year.
China has been the most courageous country in building nuclear power, with the largest number of plants currently under construction. Nuclear power is facing a tough time in developed countries. The Japanese public is demanding the closure of all the country's nuclear power plants. China is at the forefront of nuclear power development. But it has been forced into this position.
Rapid economic development coupled with improvements in people's life both demand more electricity. It is impossible to exploit fossil resources forever as the supply of coal, oil and natural gas is limited. China has no choice but to develop nuclear power.
China must be the safest user of nuclear power. It should become a leading country in developing nuclear power technologies and increasing the world's knowledge of nuclear power.
It needs to do at least two things. First, it needs to promote safety in nuclear power plants, based on the technologies of the West. The former Soviet Union, the US and Japan all had severe nuclear accidents, proving there are risks. China should try to remove these risks.
Second, China should establish effective communication mechanisms（机制）between the government, power plants and the public. It's wrong to think the government can control every aspect of nuclear power plant construction.
The opposition to nuclear power program in developed countries has prevented them from building new plants, but they already have many. These governments are reluctant to close these plants despite strong opposition, because they cannot find better substitutes.
Nuclear power only occupies 1.8 percent of China's current electricity grid（输电网）, much lower than the proportion in many developed countries. China's nuclear power plan should introduce the advantages of the technologies of other countries and also be creative in providing security. Its space technology is not the most advanced, but its launch safety measures have proven to be among the best.
China's high-profile high-speed railway development has drawn a lot of controversy, as will the active attitude towards developing nuclear power. But China cannot just copy what the developed countries have done. The development of nuclear power must be unique to China and it must be a ground-breaking success. But now, the real test lies ahead. In the third paragraph the writer focuses on ______.
| A．the reason why China is to develop nuclear power |
| B．the difficulty China has in developing nuclear power |
| C．the measures China will take to develop nuclear power |
| D．the benefits China will have by developing nuclear power |
What attitude do people in developed countries have towards nuclear power program?
| A．Supportive. | B．Opposed. | C．Indifferent. | D．Objective. |
. If the Chinese government is to develop nuclear power, it needs to ______.
| A．copy exactly what the developed countries have done |
| B．depend entirely on domestic scientists and technologies |
| C．avoid people’s involvement in nuclear power plant construction |
| D．do everything in its power to guarantee safety in nuclear power plants |
What is the future of China’s nuclear power program according to the text?
| A．It will be unique but can hardly pass too many tests. |
| B．It will be full of controversy but carried out firmly. |
| C．It will be on a smooth way to a ground-breaking success. |
| D．It will receive much opposition from developed countries. |
WASHINGTON(Reuters)‑People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer (胰腺癌), an unusual but deadly cancer, researchers reported on Monday.
People who drank mostly fruit juice instead of sodas did not have the same risk, the study of 60,000 people in Singapore found.
“Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits,” said Mark Pereira of the University of Minnesota, who led the study.
“The high levels of sugar in soft drinks may be increasing the level of insulin(胰岛素) in the body, which we think contributes to pancreatic cancer cell growth,” President said in a statement.
Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and his colleagues said they followed 60,524 men and women in the Singapore—Chinese Health Study for 14 years.
Over that time, 140 of the volunteers developed pancreatic cancer. Those who drank two or more sweetened soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer.
Pereira said he believed the findings would apply elsewhere.
“Singapore is a wealthy country with excellent healthcare. Favorite pastimes(消遣) are eating and shopping, so the findings should apply to other western countries.” he said.
But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious.
“Although this study found a risk, the finding was based on a relatively small number of cases and it remains unclear whether it was a causal(因果的) connection or not.” Said Mayne, who serves on thee board of the journal, which is published by the American Association for Cancer Research.
Pancreatic cancer is one of the deadliest form of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34, 290 die of it.We can infer from Pereira’s word that_________
| A．the healthcare in Singapore should be greatly improved |
| B．2 soft drinks a day are considered harmful to health |
| C．87 out of 140 volunteers developed pancreatic cancer |
| D．sugar might not be the only cause of pancreatic cancer. |
How does Susan seem to feel about the findings of the study?
| A．Satisfied | B．Doubtful | C．Worried | D．Hopeful |
The best title of the text might be_______
| A．The Deadliest Forms of Cancer |
| B．Drink Fruit Juice Instead of Sodas |
| C．A Study in University of Minnesota |
| D．Sugary Soft Drinks Lead to Cancer |

The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis’s Swamp (沼泽地) creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack’s dare. They liked camping, but not near this swamp.
“So,” Martin asked as they sat watching the hot coals. “How did this place get its name ? ”
“Are you sure you want to hear it ? It’s a scary story,” warned Jack.
“Of course!” cried out Tom. “If there were anything to be scared of, you wouldn’t have chosen this place!”
“Ok, but don’t say I didn’t warn you,” said Jack, and he began this tale.
“Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in . In those days, the area looked quite different ---- it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice.
“ ‘You are clearing too much land, ’ warned one old man. ‘ The land is a living thing. It will hit back at you if you abuse it. ’
“ ‘ Silly fool,’ said Dennis to himself. ‘If I clear more land, I can grow more crops. I’ll become wealthier. He’s just jealous!’”
“Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants.”
“What happened? ” Martin asked. It was growing colder. He trembled, twisting his body closer to the fire.
“The land hit back ---- just as the old man warned, ” Jack shrugged. “Dennis disappeared Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found.”
“What a stupid story, ” laughed Tom. “Plants can’t …” Before he had finished speaking, he screamed and fainted (晕倒). The other two boys jumped up with fright, staring at Tom.
