Why do some people flush when they drink alcohol? This effect is a common reaction to alcohol among East Asians. It affects about 36 percent of Japanese, Chinese and Koreans.
For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation, increased heart rate, shortness of breath and headaches.
The cause is a genetic difference that they are born with called an ALDH2 deficiency (缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus (食道) from drinking alcohol.
The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.
Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world’s population.
Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increased the risk of esophageal cancer.The underlined word “flush” in Paragraph 1 probably means “_________”.

I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent.
I no longer consider myself the center of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today.
So here’s what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion, the bigger pay-check….
Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure, it is work. Pick up the phone. Send an e-mail. Write a letter. And realize that life is the best thing and that you have no business taking it for granted.
It is so easy to waste our lives, our days, our hours, and our minutes. It is so easy to exist instead of to live. I learned to live many years ago. Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what , today, seems to be the hardest lesson of all.
I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned.
By telling them this: Read in the backyard with the sun on your face. Learn to be happy. And think of life as a deadly illness, because if you do, you will live it with joy and passion as it ought to be lived.

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid
to cut the emission of greenhouse gases blamed for global warming.Thanks to special bacteria in their stomachs, kangaroo farts contain no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, livestock passing wind contribute a surprisingly high percentage of total emissions in some countries."Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government."And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said.Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.The idea is controversial（争议）, but about 20 percent of health conscious Australians are believed to eat the national symbol already."It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal（散养动物）," said Peter Ampt of the University of New South Wales's institute of environmental studies.
56. According to the passage, global warming is now mainly caused by _____ .
A. methane B. carbon dioxide C. livestock passing wind D. not mention in this passage
57. What does the underlined phrase “the idea”（paragraph 9）refer to?A. Australians should give kangaroo-style stomachs to cattle and sheep.B. The bacteria could make the digestive process much more efficient.C. Australians should farm fewer cattle and sheep and just eat more kangaroos.D. The bacteria could potentially save millions of dollars in feed costs for farmers.
58. How will Australian scientists solve the problem of global warming?
A. Eating more kangaroos.
B. Killing more cattle and sheep.C. Letting cattle and sheep pass less wind.D. Transferring the special bacteria in kangaroos’ stomachs to cattle and sheep.

Across the world, 1.1 billion people have no access to clean drinking water. More than 2.5 billion people lack basic sanitation (卫生设备).
The combination proves deadly. Each year, diseases related to inadequate (不充足的) water and sanitation kill between 2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe drinking water is a precondition (前提) for health and the fight against child death rate, inequality between men and women, and poverty.
Consider these facts:
The average distance that women in Africa and Asia walk to collect water is 6 kilometers.
Only 58 percent of children in sub-Saharan Africa are drinking safe water, and only 37 percent of children in South Asia have access to even a basic toilet.
Each year in India alone, 73 million working days are lost to water-born diseases.
Here are three ways you can help:
(1) Write Congress
Current US foreign aid for drinking water and sanitation budgets only one dollar per year per American citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.
(2) Donate to a project with a faith-based organizations
Many US religious groups already donate to water and sanitation projects, working with partner organizations abroad. Simply a single project by a US organization can make safe water a reality for thousands of people.
(3) Support nonprofit water organizations
Many US-based nonprofits work skillfully abroad in community-led projects on drinking water and sanitation. Some organizations are large, others small, some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them generously.
53. The passage is probably written for .
A. Americans B. people in developing countries
C. religious leaders D. nonprofit water organizations
54. What is the problem that the facts exposed?
A. Inequality between men and women.
B. Many people have no access to clean drinking water.
C. Less effort has been made to improve the basic sanitation.
D. Children suffer most from the lack of basic sanitation.
55. The purpose of the passage is to arouse people to .
A. help the developing countries
B. help solve the water shortage and sanitation problem
C. support nonprofit water organizations
D. help get rid of water-related diseases around the world
56. Which is the best title of the passage?
A. From Water Shortage and Sanitation to Poverty
B. Developing World, A Place Needs Help
C. Water Shortage and Sanitation, What Can We Do?
D. Water Shortage and Sanitation

Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.
The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”
The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.
Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.
The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.
49. The underlined word “scenario” in Paragraph 2 probably means .
A. imagination B. intention C. expectation D. prediction
50. From the passage, we can infer that .
A. corals have no difficulty in adapting the temperature change
B. if we take quick actions we can avoid the destruction of corals
C. we can find corals in many areas of the seas or oceans
D. the algae help corals to live
51. Which of the following is NOT the cause of the destruction of coral on the Great Barrier Reef?
A. Direct sunshine. B. Over-fishing.
C. Global warming. D. Pollution.
52. By saying “Coral has a narrow comfort zone” (Para. 3), the author means .
A. coral can only live in a small area
B. coral prefers a crowded place
C. coral can hardly adapt to the temperature change
D. coral grows best in a small area
