     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".

1. The underlined word "scenario" in Paragraph 2 probably means _____.[     ]
A. imagination
B. intention
C. expectation
D. prediction 2. 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 3. 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. 4. 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

     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.

1. The passage is probably written for _____. [     ]
A. Americans
B. people in developing countries
C. religious leaders
D. nonprofit water organizations 2. 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. 3. 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 4. 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

完形填空。     Here"s a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting
for prolonged periods-even if you also exercise regularly-could be    1    for your health. And it doesn"t matter
where the sitting takes place-at the office, at school, in the car or before a computer or TV-just the overall
number of hours it    2   .
     Research is preliminary, but several studies    3    people who spend most of their days sitting are more likely
to be fat, have a heart attack or even die.
     In an editorial    4    this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish
School of Sport and Health Sciences suggested that authorities rethink how they define    5    activity to highlight
the dangers of sitting.
     While health officials have issued guidelines    6    minimum amounts of physical activity, they haven"t
suggested people try to limit how much time they spend in a seated    7   .
     "After four hours of sitting, the body starts to send    8    signals," Ekblom-Bak said. She explained that genes
regulating the amount of glucose and fat in the    9    start to shut down.
     Even for people who   10  , spending long stretches of time sitting at a desk is still harmful. Tim Armstrong,
a physical activity expert at the World Health Organization, said people who exercise every day-  11   still spend
a lot of time sitting-might get more benefit if that exercise were spread across the day,   12   in a single bout.
     That wasn"t   13   news for Aytekin Can, 31, who works at a London financial company, and spends most
of his days sitting   14   a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art 
  15    wrestling, and also does Thai boxing.
     "I"m sure there are some detrimental   16   of staying still for too long, but I hope that being   17   when I can
helps," he said. "I wouldn"t want to think the sitting could be   18   dangerous."
     Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years,
researchers found people who sat   19   had a higher death risk, independently of whether or not they exercised.
     Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from
working at their desks to sitting in cars.
     Experts said more research is needed to   20   just how much sitting is dangerous, and what might be
possible to offset those effects.

     Good nutrition and a balanced diet will help your children grow up healthily. No matter how old your kids
are, you can take steps to improve nutrition and to encourage smart eating habits. Here are some suggestions.
     Family Meals
     Family meals are comforting for both parents and kids. Children like to guess what they are going to have
and parents get the chance to introduce new foods to children and to find out which foods they like and which
ones they don"t.
     Teens may turn up their noses at your plan of a family meal. It is not surprising because they"re trying to
establish independence. Yet studies find that teens still want their parents" advice, so they use the mealtime as
a chance to reconnect.
     Stocking Up on Healthy Foods
     Kids, especially younger ones, will eat mostly what they can get at home. That"s why it"s important to
control the supply lines-the foods which you serve for meals and have on hand for snacks. You should have
enough fruits, vegetables, lean meat and other good sources of protein, such as eggs and nuts, and healthy
snacks, such as yogurt, peanut butter and whole-grain biscuits.
     Being a Good Example
     The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the
adults they see every day. By eating fruits and vegetables and avoiding fast food and sugary drinks, you"ll be
sending the right message.
     No Conflicts over Foods
     Parents might find themselves shouting at children to get them to have healthy foods in front of them. This
in fact can make children dislike what they are asked to eat.
     Get Kids Included
     Most kids will enjoy making the decision about what to make for dinner. Talk to them about making choices
and planning a balanced meal. It can help prepare them to make good decisions on their own about the foods
they want to eat.
1. Family meals provide the chances for parents to do the following things EXCEPT _____.
[     ]
A. guessing what kids are going to have
B. finding what kids like and dislike
C. introducing new foods to kids
D. reconnecting with kids
2. The underlined sentence in the third paragraph probably means _____.
[     ]
A. teenagers may be interested in your plan of a family meal
B. teenagers may help you to make a plan of a family meal
C. teenagers may show no interest in your plan of a family meal
D. teenagers may refuse to help you to make a plan of a family meal
3. According to the article, which should NOT be done by parents?
[     ]
A. Forming a healthful eating habit themselves.
B. Forcing kids to have vegetables.
C. Stocking up on some fruits at home.
D. Making meal plans with kids.
4. What"s the best title for the passage?
[     ]
A. How to eat healthily.
B. How to grow up healthily.
C. Help kids form healthful eating habits.
D. Help kids know what a healthful meal is.
请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词或词组(每个空格
填词最多不超过三个单词)。
     You are what you eat so maybe it"s time you started eating sensibly. Experts at the first Chinese Students
Nutrition and Health Festival in Kunming last week singled out (挑选) several bad eating habits.
     ●Watching television while having meals or snacks (零食).
     Doing this means you don"t pay attention to your food, forget how full you are, and so overeat. It can also
cause digestion (消化) diseases. One way to avoid this is only to eat in certain areas of your home.
     ●Replacing meals with snacks.
     Many students think that eating small snacks can help them diet. But it often results in overeating and health
problems related to a lack of vegetables, carbohydrates (碳水化合物), proteins and vitamins. Snacking only
works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt (酸奶).
     ●Having drinks rather than water.
     Fizzy (有气泡的) drinks and fruit juice are usually high in calories and sugar, which can cause weight
problems. Water is important in making your brain cells and every organ in your body work properly. For
your body to burn fat, it needs at least eight glasses of pure water a day. Liquids like soda (苏打水) and
coffee actually take water away from your body.
     ●Choosing meat and certain vegetables over others.
     Different foods provide different kinds of nutrition. If you don"t have a balanced diet, this can result in
malnutrition (营养失调) and a weaker body.
     ●Eating throat tablets (润喉片) as if they were sweets.
     If you eat throat tablets when you have no throat disease, they may affect the bacteria (细菌) in your
mouth and cause real throat problems.

     Most rain forest lie close to equator (赤道), where the climate is often mild and there are long hours of
sunshine. The warmth of the land heats the air above, causing it to rise and tiny drops of water to fall as rain.
The rainfall can reach at least 98 inches a year. This wet, warm world with plenty of sunlight is perfect for
plants to grow, so the trees grow fast with green leaves all the year round. The trees themselves also have an
effect on the climate. They gather water from the soil and pass it out into the air through their leaves. The wet
air then forms clouds, which hang over the treetops like smoke. These clouds protect the forest from the
daytime heat and night-time cold of nearby deserts, keep temperatures fit for plant growth.
     Rain forests slightly farther away from the equator remain just as warm, but they have a dry season of
three months or more when little rain falls. Tree leaves fall during this dry season and new leaves grow when
the wet season or monsoon (雨季) begins. Thus these areas are known as the "monsoon forest".
     Another type of rain forest grows on tropical mountains. It is often called the "cloud forest" because clouds
often hang over the trees like fog.
     The rain forest is the ideal place for the growth of many different trees. Most of them depend on animals
to eat their fruits and spread their seeds. When the fruits are eaten, the seeds inside them go undamaged through
animals, stomachs and are passed out in their droppings. The seeds lying on the forest floor then grow into
new trees.
1. The climate of the rain forests near the equator is _____.
[     ]
A. mild, wet and windy
B. hot, rainy and foggy
C. warm, wet and sunny
D. hot, wet, cloudy
2. We can learn from the passage that _____.
[     ]
A. tree leaves are green all the time in the monsoon forest
B. there is a dry season in the cloud forest on tropical mountains
C. clouds help the plants in the rain forest near the deserts to grow
D. the formation of climate in the rain forest has little to do with the trees
3. According to the passage _____ play the most important role in the spreading of seeds.
[     ]
A. animals
B. droppings
C. fruits
D. winds
4. This passage is most likely to be found in _____.
[     ]
A. a travel guide
B. a storybook
C. a technical report
D. a geographical book
