No air means death. Although we can"t see it, there is air around us. So air is everything and it gives life
to every living thing. Bad air makes people ill. We must have fresh air to keep us in good health.
In the city there are a great many people and there are too many cars running on the roads. The gas which
the cars spread out is full of poison. Every day we breathe it in again and again. This makes us feel sick.
Besides so many cars, there are many factories too. From the chimneys of these factories, we get the
smoke usually in black and grey colour. This kind of smoke, when it mixes the air, is dangerous to our health.
It is because smoke contains many poisonous solids and gases. So in order to keep us healthy we have to go
out to the countryside to breathe more fresh air. Or we can go up hills to get more fresh air. |

Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about
our diets, our bodies soon become loose and fatty and our systems slow moving.
There are some aspects (方面) of our unhealthy lives that we cannot avoid. I am thinking of such features
of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects
of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport
or other. While it is true that every weekend you will find people playing football and hockey in the local park,
they are outnumbered a hundred to one by the people who are simply watching them.
For those who do not particularly enjoy competitive sports - and it is especially difficult to do so if you
are not good at them - there are such separate activities as cycling, walking, jogging and swimming. What
often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are
doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only
half way to good health, because, according to the experts, you must also master the art of complete mental
and physical relaxation (放松). It has to do with deep breathing, emptying your mind of all thoughts,
meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems
for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have
improved in a material sense we have found it increasingly necessary to go back to forms of activity-physical
effort on the one hand and relaxation on the other - which were the natural way of life of our forefathers. |

| [ ] |
A. the causes of unfitness
B. bad features of modern living
C. the things we can completely do away with
D. unavoidable things in town |

| [ ] |
A. don"t do them very often
B. don"t do them actively enough
C. find it hard to get out of our armchairs
D. don"t find them interesting |
| 3. To be healthy we must _____. |
| [ ] |
A. keep fit and active
B. keep fit and learn to relax
C. be active and practise Yoga
D. have a sound mind |
| 4. Our forefathers were healthy because _____. |
| [ ] |
A. their way of life closely connected with both exercise and relaxation
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted |

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, 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." |
| 1. What can be the best title of the passage? |
| [ ] |
A. Sea Life Facing Danger
B. Scientist Researching Seawater
C. Oceans Becoming More Acidic
D. Climate Change Affecting Seawater |
2. Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a. Sea life is endangered.
b. CO2 goes into the surface water.
c. The ocean chemistry is affected.
d. CO2decreases the PH and makes the seawater more acidic.
e. CO2 levels in the atmosphere go up. |

A. a-b-c-d-e
B. e-b-c-d-a
C. a-e-b-c-d
D. e-d-c-b-a |
| 3. Scientist Robert Dore came to the conclusion based on ______. |
| [ ] |
A. his research and analysis
B. the expectation of other scientists
C. some former theory
D. a major cause of climate change |
| 4. What does the passage want to tell us most? |
| [ ] |
A. It takes time to make a scientific study.
B. Atmospheric CO2 is doing harm to sea life.
C. Robert Dore is a committed and serious scientist.
D. Measures should be taken to prevent the potential catastrophe. |

Could you stand the noise of a street-sweeping truck going up and down the street outside of your house
three times a week at 4 a.m.? The noise-described by Blomberg as "loud as a NASCAR (全国运动汽车竞赛
协会) race car but at a speed of 5 miles per hour-annoyed him so much that he tried to persuade the city to
rearrange for street sweeping to begin at 6 a. m. He also founded the non-profit Noise Pollution Clearinghouse,
an organization that provides research and information to others whose request for quiet might otherwise fall
on deaf ears.
Hearing loss is the most obvious medical consequence of noise pollution, but it is hardly the only one,
explains environmental psychologist Airline Bronzaft. In her research, Bronzaft found that constant noise
exposure can reduce children"s learning ability and cognitive (认知的) development."Most importantly, each
day, you"ve got to take a break from sound regularly." says Bronzaft.
"The bad news," says Blomberg, "is that the last century was the noisiest in history. The good news," he
continues, "is that the greener we get, the quieter we"ll also get." Electric cars and lawn equipment make less
noise, just as more fuel-efficient vehicles. Improved technology can also provide measures to make the
problem less serious. Police cars could replace those loud sirens (警报器) with models that better aim the
sound in one direction.
"I don"t think you can name a noise source that I can"t find a way to make it quieter," says Blomberg. But
the real challenge is to change people"s attitudes." In the 1960s, we made it unacceptable to throw litter out of
the window of your car," he says. Today it"s time to recognize that"noise is to the soundscape as rubbish is
to the landscape." The goal is to "create a culture where you do not throw your "noise" litter out of the
window." |

In many societies, there is often greater acceptance of light skin than dark skin. Light skin may be seen
as a mark of beauty, intelligence and success. These beliefs can lead to social pressure even within the same
racial or ethnic group, if some members are darker skinned than others.
The result is that skin lightening has become a common activity across Africa, Asia and other areas of
the world. More and more people with dark skin are using skin-lightening products, even if they may face
health risks.
They believe that having whiter skin will improve their lives. Many people think they will have a better
chance of getting a job or marrying into a better family. Or they want to look like what their society generally
considers beautiful.
Some beauty care products and soaps contain chemicals that make skin lighter. This process is also called
bleaching. But some of the chemicals are extremely dangerous. One of the chemicals has been linked to
kidney (肾) damage and some kinds of cancer. It also causes low birth weight in babies when mothers use it
during pregnancy.
At first, bleaching products make the skin color lighter. But after long-term use they can cause problems.
They can even make some skin darker. The chemicals in the products block and break down the natural
process that gives color to skin. The skin loses its natural barrier to protect against sunlight. Then the skin
can become thick and discolored. Usually the person will use more of the product in an effort to correct the
problem, but this only makes it worse.
Fatimata Ly treats skin conditions in the Senegalese capital, Dakar. Doctor Ly says skin bleaching has
become a problem throughout Senegal. She says the chemicals are now more dangerous because they are
stronger. Some cases have resulted in blackened fingernails, infections and permanent skin damage.
And these are not the only risks. Experts say some people who change their skin color suffer emotional
damage. They feel regret and sadness. They feel that instead of risking their health, they should have learned
to love and accept their skin color as it was. |
| 1. Which of the following words can replace the underlined word "bleaching"? |
| [ ] |
A. whitening
B. changing
C. lighting
D. pleasing |
| 2. Why has the skin lightening become a common activity all over the world? |
| [ ] |
A. There are many products that can make the dark skin light.
B. Many people with dark skin have no confidence.
C. Relatively speaking, light skin has more advantages over dark skin.
D. People with dark skin are forced by the pressure of their families. |
| 3. According to the text the following are the risks using the bleaching products EXCEPT ______. |
| [ ] |
A. blackened fingernails
B. permanent skin damage
C. emotional damage
D. a waste of time and money |
4. From the text we can conclude the writer"s attitude toward using the bleaching products is
probably ______. |
| [ ] |
A. supportive
B. positive
C. doubtful
D. negative |

Illegal removal of coral (珊瑚) along Sri Lanka"s coastline increased the amount of destruction on the
island by last December"s tsunami, say researchers.
Harindra Fernando, a fluid dynamicist (力学家) at Arizona State University in Tempe, made the connection
after a visit to his native Sri Lanka earlier this year. While serving as a scientific expert and translator for a
BBC-documentary team, he chatted with locals who said they saw the tsunami turn sideways when it hit
coral-which would have made it less powerful than in coral-free areas. Fernando linked this to trucks he had
seen last year carrying piles of coral away from the sea.
Using the eyewitness reports, estimates (估算) of wave heights, and a series of divers to check the
presence or absence of corals, Fernando and his colleagues produced a map of coral gaps and wave flooding
along Sri Lanka"s southwest coast.
The tsunami reached significantly farther inland through the gaps: in one instance, the water traveled 1.5
kilometres long and knocked a passenger train off its tracks, killing 1,700. But only a few kilometers away,
where the coral was still undamaged, the wave travelled just 50 metres inland and caused no deaths.
There is a similar phenomenon. In Nicaragua in 1992, a tsunami poured through a break in the coral reef
made to let boats through. "Within this passage, water went one kilometre inland," says Fernando. "But
nearby, where the coral was undamaged, there were still beach umbrellas standing."
In Sri Lanka, coral is illegally mined to provide souvenirs for tourists, or to be used in house paint. Coral
harvesters sometimes blow it up with dynamite (炸药) in order to collect fish at the same time. Often, the
reefs in the best shape are those in front of hotels, as the hotel owners maintain them for the tourists.
Fernando hopes that his findings will encourage the Sri Lankan government to enforce (实施) its laws against
coral mining. |
