We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.

试题分析：本文围绕着人类移民火星而展开论述。首先从火星与地球的相似之处讲到移民火星在理论上的 可行性以及搬迁过程，继而又谈论了人类因人口的急剧增加而向外空发展的必要性。最后分析了人类科技的发展和成就大大增加了使火星适合人类居住和人类移民火星的可能性。
小题1:A主旨大意题。文章首段提出human beings will move to Mars，然后围绕此话题展开论述，所以文章中心应该是将火星地球化问题。所以A选项正确。
小题2:B词意猜测题。由后句so that Earth’s life forms can survive there.可判断为了让地球上的生命能在火星上存活，就要改变火星上的条件以便更适合地球上生命的生长，所以alter应该是改变的意思。
小题3:D推理判断题。由第二段Terraforming means altering a planet’s surface so that Earth’s life forms can survive there.可知使火星地球化的目的是让地球上生命能在火星上存活，故D选项正确。
小题4:A细节理解题。文章第二段Mars resembles the earth in many aspects。。。和 These resemblances have caused many people to consider a centuries-long project: to terraform Mars.，由此可知A选项正确。
小题5:A推理判断题。A 乐观的；B 否定的；消极的；C 怀疑的；D 客观的。从文章倒数第二段While the possibility of such a project is small, it is not impossible可知作者对此事持乐观态度。

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.
小题1: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. |
| A．Satisfied | B．Doubtful | C．Worried | D．Hopeful |
| 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 |
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.
小题1: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 |
| A．Supportive. | B．Opposed. | C．Indifferent. | D．Objective. |
| 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 |
| 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. |

How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (内燃发动机烟雾) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and then enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排气净化器) that reduce automobile emissions. Govemments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (无铅燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in car ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, which is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
小题1:What tends to give rise to the highest death toll according to the passage?
| A．The lack of tight environmental protection standards. |
| B．The increasing numbers of the diesel cars and trucks. |
| C．The frighteningly high death rate from deadly cancer. |
| D．The world’s serious air pollution such as soot and dust. |
| A．consequence | B．solution | C．reform | D．design |
| A．the diesel soot is too small to be seen |
| B．the diesel soot is much too poisonous to breathe |
| C．the diesel soot roots in lungs and gets into blood |
| D．the diesel soot can also contribute to deadly cancer |
| A．the global economic growth is mainly to blame for air pollution and climate change |
| B．the developing countries are repeating the same mistakes as the developed ones made |
| C．the ecological situation and air pollution in India are becoming worse and worse |
| D．the unbeatable air is increasingly becoming a major killer throughout the world |
| A．the making of tougher environmental regulations alone is of little use |
| B．more sever regulations should be made to handle air pollution |
| C．the urban construction in western developed countries is the best choice |
| D．the pace of development has to be slowed down to reduce air pollution |
The latest edition of the annual Institute of International Education（IIE）and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.
Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.
Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.
Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.
The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
小题1:Which ranked the third place sharing US higher education?
| A．Saudi Arabia | B．South Korea | C．Canada | D．India |
| A．The US colleges are better than those in China. |
| B．Each family in China has only one child. |
| C．China lacks enough educational resources. |
| D．Chinese students can enter varieties of US colleges. |
| A．The number of Chinese students going to the US has increased by 23%. |
| B．The University of California has contributed to Asian education greatly. |
| C．Chinese student populations in the US mainly consist of undergraduates. |
| D．Chinese students know more about US higher education than before. |
| A．Chinese College Students Rush to US Schools |
| B．The Large Number of Chinese Students in the US |
| C．Chinese Students Make Up Largely Foreign Students in the US |
| D．Asian Middle School Students in the US Universities |
