     Trees are useful to man in three important ways: they give him wood and other useful things, they give
him cool places, and they help to stop drought and flood.
     Unluckily, in many parts of the world, man has not found that the third of these points is the most
important. Man wants to make money from trees, so he has cut them down in large numbers, only to find
that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
     This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil, make the rain in, and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
1. The most important points of trees to man is ________.
A. they help him to make money            
B. they give him cool
C. they give him wood and other things      
D. they help him to stop drought and floods
2. In many places forests slowly disappear because ________.
A. many trees have been cut down by man            
B. new trees are not well looked after
C. man has not paid enough attention to planting trees    
D. all the above
3. Land becomes desert after all trees are cut down because ________.
A. roots of trees break up the soil      
B. there are too many rainfalls to make it
C. strong winds bring a lot of sand      
D. no tree keeps the rain and protects the top-soil.
4. Which title best fits the passage?
A. Trees and Man                        
B. The Function of Tree Wood
C. How do People do with Trees?            
D. The Usage of Tree Roots

阅读理解     Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat.
Wind is one of our cleanest and richest power sources(来源) as well as one of the oldest. Evidence shows that windmills(风车)began to be used in ancient Iran back in the seventh century BC. They were first
introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of
using wind power.
    For many centuries, people used windmills to grind(磨碎)wheat into flour or pump water from deep
underground. When electricity was discovered in the late 1800s. people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the1940s
when electricity was available to people in almost all areas of the United States, windmills were rarely
used.
     During the 1970s,people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity .People also realized that the supply of coal and gas would not last
forever .Then, wind was rediscovered ,though it means higher costs. Today ,there is a global movement to supply more and more of our electricity through the use of wind.1. From the text we know that windmillsA. were invented by European armies            
B. have a history of more than 2,800 years
C. used to supply power to radio in remote areas    
D. have rarely been used since electricity was discovered2. What was a new use for wind power in the late 19th century?A. Sailing a boat.                            
B. Producing electricity
C. Grinding wheat into flour.                  
D. Pumping water from underground3. One of the reasons wind was rediscovered in the 1970s is that_________.A. wind power is cleaner                    
B. it is one of the oldest power sources
C. it was cheaper to create energy from wind    
D. the supply of coal and gas failed to meet needs4. What would the author probably discuss in the paragraph that follows?A. The advantages of wind power.            
B. The design of wind power plants.
C. The worldwide movement to save energy  
D. The global trend towards producing power from wind

     The hole in the Earth"s ozone layer (臭氧层)has until now protected Antarctica from the worst effects
of global warming. But scientists have warned that as the hole closes up in the next few decades,
temperatures on the continent could rise by around 3C on average, with melting ice contributing to a
global sea level increase of up to 1. 4 metres.
     In the past decades the western Antarctic has seen rapid ice loss as the world has warmed,but the
other parts of the continent have, paradoxically, been cooling,resulting in a 10% increase in ice in the seas
around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica,
making much of the continent surface colder than usual.
     But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to
repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the
Antarctic will face the full impact of global warming. This means an increase in average air temperatures
of around 3? and a reduction in sea ice by around a third.
     The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who
monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But
once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very
quickly. " Thinning ice sheets cause ice to break away from the continent and to melt even faster.
Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent
decades.
     Johnson believes that international action to reduce global warming is required immediately or it may
be too late. "Everything is connected-Antarctica may be a long way away but it is an important part of
the Earth"s  system," said Johnson. "It contains 90% of the world"s ice, 70% of the world"s fresh water
and that is enough, if it melts completely,to raise sea levels by 63 metres. "
     Even in a worsecase situation scientists don"t expect the ice to entirely disappear,but predict that,
because of the melting ice sheets,average sea level rise will be around 1. 4 metres higher by the end of
the century. 1. The underlined word "paradoxically" (in Paragraph 2) most probably means "________". A. rapidly    
B. approximately
C. contradictorily  
D. apparently2. What is the effect of the hole in the ozone layer on Antarctica?A. It is making much of the continent colder.
B. It is causing the ice to melt faster.
C. It is making the effects of global warming in the region worse.
D. It is reducing the amount of water in Antarctica. 3. What do scientists think is the biggest danger facing Antarctica?A. Rising sea levels.
B. Warming sea water temperature.
C. Water pollution.
D. Growing ice sheets. 4. Which of the following is TRUE according to the passage?A. Antarctica contains most of the world"s fresh water.
B. The average temperature has increased by 3 degree centigrade in recent decades.
C. Antarctica is currently experiencing the full effects of global warming.
D. Ten percent of Antarctica"s ice has already been lost. 5. The BEST title for the passage is ________. A. Our planet in danger
B. Antarctica melting away
C. Action plan to save Antarctica
D. Let"s save the ozone layer

阅读理解     If you are having trouble falling asleep, you are in good company. About 65% of Americans said they
have sleeping problems a few nights each week, according to a recent study by the National Sleep
Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed(沮丧的).
But before you go to a doctor for advice, it is worth examining your sleeping habits one more time. Some
of your favorite evening habits may have something to do with the sleeping problems.
     1.Setting a Bright Alarm Clock.
     The light of your bright alarm clock can prevent you from falling asleep. You can make your room as
dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your
cellphone alarm may also do the trick.
    2.Counting Sheep
     When you just can"t fall asleep, it"s useless to stay in bed to count sheep. If you"ve been trying to fall
asleep for more than 30 minutes, the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it, you"ll be going back to
bed really tired.
     3. Exercising Late at Night
     Daytime workouts(锻炼) will keep you full of energy for hours. That"s why you don"t want to exercise within three hours of hitting the sack. Fierce(剧烈的)physical activity raise your body temperature and
pumps your energy level-both are bad for a good night"s sleep.1. What can we learn from the first sentence of the passage?
A. It"s not good to fail to fall asleep at night.
B. People in a good company often have sleeping problems.
C. There are many people who have sleeping problems.
D. You should find someone to talk to if you can"t fall asleep.
2. The underlined part "hitting the sack" in the last paragraph means "_____".

A. The bad results of getting too little sleep.
B. Why the bright alarm clock keeps you awake.
C. What to do if you can"t fall asleep after 30 minutes.
D. Why watching TV and reading books make people sleepy.
4. By writing the passage, the writer mainly wants to tell us _____.
A. why so many people can"t sleep well at night
B. how to enjoy a good night"s sleep
C. that sleeping problems are troubling more and more people
D. that people may solve their sleeping problems by some habits
