阅读理解。     About 97% of the world"s water is salty and is found in our oceans and seas. But, as we can"t drink
seawater, how can it be important?
     Every part of our seas and oceans contains an amazing number of animals and fish that live at different
ocean depths. Most of the different species of animals and fish depend on simple plants for their food.
These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon
dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe.
How important seawater is!
    Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in
large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains
are delicately balanced.
     The bad news about the food chains in the oceans is that they are under threat because of man. People
once thought that the oceans were so big that it didn"t matter if we dumped rubbish into them or caught
huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans
have started to drop.
    Thankfully, the world is taking steps to protect the future of our oceans by introducing international
agreements to protect marine habitats (海域). Most countries have introduced fishing restrictions (限制)
to protect fish stocks in the oceans and new techniques are being pioneered to deal with pollution. Finally,
the importance of protecting oceans is being made known to more people. This is just the beginning of a
long process to protect the oceans for our future. We depend on the oceans for fish which are an important
part of the human diet. How important seawater is! 1. Which of the following is the proper order of the food chain? A. small animals→algae→microscopic animals→large animals man
B. algae→microscopic animals→large animals→larger animals→man
C. small animals→algae→large animals→microscopic animals→man
D. microscopic animals→algae→large animals→larger animals→man 2. People used to think that the rubbish thrown into the sea ____. A. wouldn"t harm the fish in the sea
B. would change the balance of the food chain
C. would be broken down in the sea
D. wouldn"t do much harm to the sea 3. From the passage, we learn that ____. A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. too much fishing has caused the decrease in fish stocks
D. it won"t be long before the problems concerning oceans will be solved 4. Which of the following is NOT a way being used to protect oceans? A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people"s awareness of the need to protect oceans. 5. What would be the best title of the passage? A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.
D. How to deal with seawater pollution.

阅读理解。     The world itself is becoming much smaller by using modern traffic and modern communication means.
Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the
biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We
see it, smell it, drink it and even hear it.
     Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem
was not so serious because there were not so many people. When the land was used up or the river was
dirty in one place, man moved to another place. But this is no longer true.
     Man is now slowly polluting the whole world.
     Air pollution is still the most serious. It"s bad for all living things in the world, but it is not the only one
kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us
angry more easily.
     Many countries are making rules to fight pollution. They stop people from burning coal in houses and
factories in the city, and from putting dirty smoke into the air. Pollution by SO₂ is now the most dangerous
kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there
will be less air pollution.
     The earth is our home. We must take care of it. That means keeping the land, water and air clean. And
we must take care of the rise in pollution at the same time. 1. _____, our world is becoming much smaller. A. Because of the rise in pollution
B. Thanks to science development
C. Because the earth is being polluted day and night
D. Because the earth is blown away by the wind every year 2. Hundreds of years ago, life was _____ it is today.A. much easier than
B. as easy as
C. much harder than
D. as hard as 3. Pollution comes in many ways. We can even hear it. Here "it" means _____. A. rubbish (垃圾)
B. noise pollution
C. air pollution
D. water pollution 4. Air pollution is the most serious kind of pollution because _____. A. it makes much noise
B. it makes us angry more easily
C. it makes our rivers and lakes dirty
D. it"s bad for all living things in the world 5. Which of the following is NOT true? A. Many countries are making rules to fight pollution.
B. The pollution of the earth grows as fast as the world population does.
C. The problem of pollution is not so serious because there are not so many people living on the earth.
D. If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting
    against the problem of SO₂.

阅读理解。     Ask someone what they have done to help the environment recently and they will almost certainly mention
recycling. Recycling in the home is very important of course. However, being forced to recycle often means
we already have more material than we need. We are dealing with the results of that over-consumption in the
greenest way possible, but it would be far better if we did not need to bring so much material home in the first
place.
     The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a
typical household"s waste in the UK. In many supermarkets nowadays food items are packaged twice with
plastic and cardboard.
     Too much packaging is doing serious damage to the environment. The UK, for example, is running out of
it for carrying this unnecessary waste. If such packaging is burnt, it gives off green-house gases which go on
to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to
produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage
customers to buy more than they need. However, a few of them are coming round to the idea that this cannot
continue, encouraging customers to reuse their plastic bags, for example.
    But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with
quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food.
But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
     There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary
material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain
to climb. 1. What does the underlined phrase "over-consumption" refer to? A. Using too much packaging.
B. Recycling too many wastes.
C. Making more products than necessary.
D. Having more material than is needed. 2. The author uses figures in Paragraph 2 to show _____. A. the tendency of cutting household waste
B. the increase of packaging recycling
C. the rapid growth of supermarkets
D. the fact of packaging overuse 3. According to the text, recycling _____. A. helps control the greenhouse effect
B. means burning packaging for energy
C. is the solution to gas shortage
D. leads to a waste of land 4. What can be inferred from Paragraph 4?A. Unpackaged products are of bad quality.
B. Supermarkets care more about packaging.
C. It is improper to judge quality by packaging.
D. Other products are better packaged than food. 5. What can we learn from the last paragraph? A. Fighting wastefulness is difficult.
B. Needless material is mostly recycled.
C. People like collecting recyclable waste.
D. The author is proud of their consumer culture.

     Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about
attitudes to dirt.
    In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical
opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger
was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So
did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt
in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a
bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
     Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor
ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply
and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have
moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter
than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
     Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children
off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an
American immunologist (免疫学家), encourages children to play in the dirt to build up a strong immune
system. And the latter position is gaining some ground.

1. The kings of France and England in the 16th century closed bath houses because _____. A. they lived healthily in a dirty environment
B. they thought bath houses were to dirty to stay in
C. they believed disease could be spread in public baths
D. they considered bathing as the cause of skin disease 2. Which of the following best describes Henry IV"s attitude to bathing? A. Afraid
B. Curious
C. Approving
D. Uninterested 3. How does the passage mainly develop? A. By providing examples.
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance. 4. What is the author"s purpose in writing the passage? A. To stress the role of dirt.
B. To introduce the history of dirt.
C. To call attention to the danger of dirt.
D. To present the change of views on dirt.
