Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now
a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming
sea life. 
     Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean
for almost two decades.
     "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change
in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been
able to record this increasing quantity of atmospheric CO2 into the ocean."
     Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be
absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact
on shellfish and coral in particular.
     "As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid (酸),
carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and
that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
     The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
     The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his
colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then
moved to those depths. Or there could be a biological explanation.
     "It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on
a whole variety of sea life from fish to coral. It's potentially catastrophic."

     Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains,
in the waves, or on the grassland, you should be aware that your sport of choice might have great influence
on the environment.
     Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside,
but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal
and Spain, golf is often held responsible for serious water shortage in some local areas.
     There are many environment-friendly sports. Power walking is one of them that you could take up today.
You don't need any special equipment except a good pair of shoes; and you don't have to worry about
resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it
will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you
feel less anxious, sleep well and have better weight control. 
    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying
products made from recycled materials. But the final goal should be"green gyms". They are better
replacements for traditional health clubs and modern sports centers. Members of green gyms play sports
outdoors, in the countryside or other open spaces. There is no special requirement for you to start your
membership. And best of all, it's free.
1. The author thinks the golf is resource-hungry because of the following EXCEPT that _____.
A. Golf wastes large areas of countryside
B. Golf runs out of much water
C. Keeping golf court in good condition needs too much energy
D. Golf is bad for people's health
2. According to the passage, which of the following is an environment-friendly sport?
A. swimming in the pool
B. hiking in the hills
C. playing basketball in the gym
D. motor racing in the desert
3. The reason why the author uses power walking as an example mainly is that ______.
A. it improves our health
B. it is an outdoor sport
C. it uses fewer resources
D. it is recommended by experts
4. The passage is developed mainly by _____.
A. examples and explanation
B. comparison and persuasion
C. facts and descriptions
D. figures and conclusion

     Positive thinkers admit when they feel frustrated (受挫折的) or depressed, they don't ignore it.
But they don't blame themselves either. Instead, they try to understand the negative thoughts and
feelings and counter (反击) them with more positive ones.
     So how do you stay positive, maintain motivated and sustain (保持) healthy behaviors? Here are
some tips:
     Look for a good role model. There is always someone who seems to be doing just what you want
to be doing. Maybe they've scheduled exercise into their workday and switched from coffee to green tea.
Learn from a successful friend, family member or colleague. Ask them how they keep healthy and follow
in their footsteps.
     Try some positive self-talk and avoid negative-talk. Take a minute to give yourself an ego boost. Repeat
some motivational words out loud to yourself. Negative talk such as"I can't do it," "I'm fat," is dangerous
for your well-being and healthy goals. Try to avoid the negative self-talk before it harms you. Remind
yourself that you deserve happiness and can make positive changes.
     Get support. Tell your friends and family about your healthy habits. It helps to have an encouraging
network.  
     Reward yourself. Treat yourself to something for your healthy efforts. Take a nice bath, get a massage,
and enjoy a new DVD or CD.
     Have a plan. Making a plan to exercise or eat healthy lunches with a friend can mean the difference of
sticking with your goals or falling off track. If you've planned for an activity, you'll likely stick with it.
You may even find that writing down your goals and steps to achieve them can help you stay on track.
Take it day by day or week by week. The process of writing down your personal action plan is a good
way to keep you honest and watch your progress or failures.
1. By writing the text the author intends to _______.
A. offer some advice on how to stay positive
B. persuade readers to learn from a role model
C. provide some solutions to personal problems
D. inform readers of some tips on physical health

A. to get lost in deep thought.
B. to think about the hardships.
C. to check what mistake you made.
D. to make you feel better about yourself.
3.Which of the following would the author Not agree to?
A. Saying some positive words to yourself helps you to feel good.
B. By staying with your companion you can avoid the negative-talk.
C. A successful friend, relative or colleague can be your role model.
D. Creating a helpful network is a good way to keep you motivated.
4.To make sure that you always stay on track, what should you do?
A. Eat out with your best friends.

     To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly
and drink alcohol in a proper amount. That is according to a study published this Monday in the Public
Library of Science Medicine Journal.
     After tracking more than 20,000 people aged 45-79 years in the United Kingdom from about
1993-2007, Kay-Tee, Khaw of the University of Cambridge and his colleagues found that people who
adopted these four healthy habits lived an average of 14 years longer than those who didn't.
     "We've known for a long time that these behaviors are good things to do, but we've not seen this
benefit before," said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council."The
benefit was also seen regardless of whether or not people were fat and what social class they came from."
     Study participants (参与者) scored a point each for not smoking, regular physical activity, eating five
servings of fruits and vegetables a day and moderate alcohol intake.
     Public health experts said they hoped the study would inspire governments to introduce policies helping
people to adopt these changes. But because the study only observed people rather than testing specific
changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviours
would surely gain 14 years.
     "We can't say that any person could gain 14 years by doing these things," said Doctor Tim Armstrong,
a physical activity expert at the World Health Organization." The 14 years is an average across the
population of what's theoretically (理论上) possible."
     "Most people know that things like a good diet matter and that smoking is not good for them", Susan
Jebb said,"We need to work on providing people with much more practical support to help them change."
1. Which of the following doesn't belong to the four healthy habits?
A. Eating five servings of fruits and vegetables a day.
B. Doing proper exercise in the morning every day.
C. Having a cigarette before going to bed every day.
D. Drinking alcohol in the proper amount every day.
2. We can learn from the passage that _____.
A. the study observed people as well as tested specific changes
B. Susan Jebb did not take part in the study
C. there is no need for people under 45 adopt these good habits
D. only those from first class can benefit from these healthy behaviours
3. What can be inferred from the passage?
A. Governments should take measures to help people change their bad habits.
B. People aged 45-79 have bad habits in the United Kingdom.
C. All the people are well aware of the harm of their bad habits.
D. People have adopted the four healthy habits after knowing they're good.
4. What would be the best title for this passage?
A. Smoking and Drinking Cuts You 14 Years
B. Healthy Habits Could Gain You Extra 14 years

     It was a village in India. The people were poor. However, they were not unhappy. After all, their
forefathers had lived in the same way for centuries.
     Then one day, some visitors from the city arrived. They told the villagers there were some people
elsewhere who liked to eat frog's legs. However, they did not have enough frogs of their own, and so
they wanted to buy frogs from other places.
     This seemed like money for nothing. There were millions of frogs in the fields around, and they were
no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were
sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money.
For the first time, the people were able to dream of a better future. But the dream didn't last long.
     The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More
worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
     The villagers decided that they couldn't just wait to see the crops failing and the children getting weak.
They would have to use the money earned to buy pesticides (杀虫剂) and medicines. Soon there was no
money left.
     Then the people realized what was happening. It was the frog. They hadn't been useless. They had been
doing an important job-eating insects. Now with so many frogs killed, the insects were increasing more
rapidly. They were damaging the crops and spreading diseases.
     Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of
insects and frogs. These sounds of the night now have a much deeper meaning.
1. From Paragraph 1 we learn that the villagers _____.
A. worked very hard for centuries
B. dreamed of having a better life
C. were poor but somewhat content
D. lived a different life from their forefathers
2. Why did the villagers agree to sell frogs?
A. The frogs were easy money.
B. They needed money to buy medicine.
C. They wanted to please the visitors.
D. The frogs made too much noise.
3. What might be the cause of the children's sickness?
A. The crops didn't do well.
B. There were too many insects.
C. The visitors brought in diseases.
D. The pesticides were overused.
4. What can we infer from the last sentence of the text?
A. Happiness comes from peaceful life in the country.
B. Health is more important than money.
C. The harmony between man and nature is important.
D. Good old days will never be forgotten.

     Feel tired lately? Has the doctor said he can't find, even with the most advanced equipment, anything
wrong with you?
     Then consider this, you might be in a state of sub-health. Sub-health, also called the third state, is
explained as a borderline state between health and disease. This is believed to be caused by the stress people
have in their everyday lives.
     According to a survey by the World Health Organization, over 45 percent of sub-healthy people are
middle-aged or elderly. The percentage is even higher among people who work in management positions as
well as students at exam-time.
     Symptoms (症状) include a lack of energy, depression, slow reaction, insomnia (失眠),nervous, poor
memory, or sometimes shortness of breath, sweating and aching in the waist and legs.
     Medical experts are offering some advice to reduce pains. They consider the key to preventing and
recovering from sub-health is to form good living habits, exercise regularly, and take part in open air
activities.
     As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables,
fruits, and fish, as they are rich in vitamins and are important to the body. They also say that a balanced diet
is very helpful in avoiding sub-health.
     Anyhow, work is not all of the life. Your life and work are an entire whole. Satisfy your needs, create
calmness in your day and renew your spirit. You will find that focusing on forming more balance in your life
can help your work improve, You will be more relaxed, better able to focus and better able to produce high
quality work.

     There is a growing problem of what to do with electronic waste such as old televisions, computers,
radios, cellular telephones and other electronic equipment.
     Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People
do not know what to do with old televisions or computers so they throw them in the trash.
     National Solid Wastes Management Association (NSWMA) state programs director Chaz Miller says
the large amount of electronic waste Americans produce is not unexpected.
     The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic
items are dumped each year, and there is a push by more states to ban the waste from landfills (垃圾填埋场)
and create recycling programs. They can be torn apart and sorted for useable parts.Mike Fannon who runs
the plant in Baltimore, says, "There are a lot of valuable metals that can be recovered and reused instead of
just putting them in the landfill, and in certain components there are some materials that should not really
be in the landfill," Fannon explained.
     Fannon says nearly 20 percent of electronic waste is recycled nationwide.Thirteen years ago, it was only
about 6 percent.Recycling rates continue to rise as more communities have banned electronics from landfills
in an effort to keep e-waste poisons like lead (铅) and mercury (汞) out of garbage dumps.
     This year several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other
states have also adopted landfill bans, e-waste recycling programs or both.Chaz Miller says more can be
done to boost electronic waste recycling.
     "We can do much better," noted Miller. "I think clearly our goal should be to do as well as we do recycling
newspapers."
1.Which of the following does NOT belong to e-waste?
A. Old televisions.
B. Old computers.
C. Old cell phones
D. Old newspapers.
2.Why is e-waste banned from landfills in many states?
A. Because it can not be recycled.
B. Because it might damage the environment.
C. Because it can be shipped to other countries.
D. Because the landfills are already full.
3.According to Mike Fannon, what might be the best way of dealing with e-waste ?
A. Recycling it.
B. Selling it.
C. Burying it.
D. Breaking it.
4.What can we learn from the passage?
A. At present, less then 10 percent of e-waste is recycled.
B. Chaz Miller works for EPA.
C. All states in the US have banned e-waste from landfills.
D. Experts are optimistic about the future of e-waste.

     What does it mean to relax? Despite hearing this term thousands of times during the course of our lives,
very few people have deeply considered what it's really about.
     When you ask people what it means to relax, most will answer in a way that suggests that relaxing is
something you plan to do later-you do it on vacation, when you retire, or when you get everything done. This
means, of course, that most other times (the other 95 percent of your life) should be spent nervous, restless,
rushed, and mad. Could this explain why so many of us perform as if life were one great big emergency
(紧急事件)? Most of us put off relaxation until our " in-basket (收文篮)" is empty. Of course it never is.
     It is useful to think of relaxation as a quality of heart that you can own on a regular basis rather than
something left for some later time. You can relax now. It's helpful to remember that relaxed people can still be
super achievers and, in fact, that relaxation and creativity go hand in hand. When I'm feeling upright, for
example, I don't even try to write. But when I feel relaxed, my writing flows quickly and easily.
     Being more relaxed includes training yourself to react differently to the dramas (戏剧) of life-turning your
melodrama (情节剧) into a sweet-drama. It comes, in part, from reminding yourself over and over again
(with loving kindness and patience) that you have a choice in how you respond to life. You can learn to relate
to your thinking as well as your situation in new ways. With practice, making these choices will translate into
a more relaxed self.
1. The writer intends to tell us _____.
A. how to find chances to relas
B. what realxation really means
C. when to relax
D. the ways to relax
2. The underlined word " it" in the second paragraph (last sentence) probably refers to _____.
A. life
B. emergency
C. relaxation
D. in-basket
3. According to the passage most people think of relaxation as _____.
A. something planned to do in the future
B. something to be done now
C. something never to be done
D. something to be done like a dream
4. What is the writer's attitude towards relaxation?
A. Only by relaxing can one achieve something
B. No one really understands what relaxation is.
C. relaxation is a good state of mind one should keep every day.
D. 95 percent of your life should be spent in a relaxed way.
