Today, ultrasonic(超聲的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解，使溶解) in liquids. Paint manufacturers(制造商) use ultrasound to do a better job of blending colors. The companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film.
The new lightweight(輕量的) type of washing machine uses ultrasonic waves to get clothes clean. Its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. The sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. There is also a new kind of dishwasher that works in much the same way.
Ultrasonic waves can shake a liquid so fast that tiny holes form all through it. The liquid is actually torn apart by this action. Almost as soon as these holes are made, they fall together again. The result is a powerful pounding action. In the dairy industry this is used for the double purpose of making homogenized(使均勻，使勻質) milk and sterilizing(使無菌) it at the same time. If you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. In order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. The result is called homogenized milk. When the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from www.nmet168.com)
1. Why does a paint manufacturer use ultrasound to do a better job of blending colors?
A. Because it is cheap to use ultrasound to blend colors.
B. Because the waves move the liquid so quickly that it can make materials mix quickly or dissolve in liquids.
C. Because they can mix chemicals by the use of sound waves.

B
Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics. but sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge. it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.
The best way to get rid of a negative serf-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍) yourself on the back, you’ll know you’re well on your way. Good luck!

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技術). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future. 
6. According to the passage, human death is now mainly caused by        .
A. diseases and aging                                 B. accidents and war
C. accidents and aging                        D. heart disease and war
7. In the author’s opinion, today’s most important advance in technology lies in        .
A. medicine          B. the Internet     C. brain cells                     D. human organ
8. Humans may live longer in the future because        .
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine
9. How long can humans live in the future according to the passage?
A. Over 100 years.                             B. More than 120 years.
C. About 150 years.                                   D. The passage doesn’t tell us.
10. We can learn from the passage that        .
A. human life will not last more than 120 years in the future
B. humans have to take medicine to build new skin cells now

"Time is a problem for children," states a news report for a new Swiss watch. Children in some countries" learn time slowly" because" they don’t wear watches" and " parents don’t really know how to teach them time. " The children grow up with this handicap and become adults (成人) —and then can’t get to work on time. Is there an answer to this problem? Of course — it’s the Flik Flak, made by a famous Swiss watch company.
The Flik Flak is being marketed as something teaching watch for children aged 4 to 10. The watch itself does not teach children how to tell time, of course; it merely " takes their imagination" by presenting the " hour" hand as a beautiful red girl named Flak and the " minute" hand as a tall blue boy named Flik. Flik points to related" blue" minutes on the dial, while Flak points to " red" hour numbers. The characters and colors combined with parental help, are supposed to teach young children how to tell time.
The watch comes equipped with a standard battery (電池) and a nylon band (尼龍表帶). Peter Lipkin, the United States sales manager for the Flik Flak, calls it " childproof if it gets dirty you can throw the whole watch in the washing ma­chine. " The product is being sold in select department stores in Europe, Asia and the United States for a suggested price of $25. Parents who buy the watch may discover that it is one thing to tell time; it’s quite another for them to be on time.
1. From the news report we know that ______.
A. parents are patient when teaching children time
B. parents have little idea of how to teach children time
C. children are likely to learn time quickly
D. children enjoy wearing the Flik Flak watch

C. the Flik Flak can take children’s imagination
D. children usually have trouble telling time if they don’t wear watches
3. The underlined word handicap in Para. 1 means
A. displeasure        B. discouragement        C. disappointment     D. disadvantage
4. The United State sales manager calls the new watch " childproof" because ______.

The volcano is one of the most surprising frightening things of nature. Maybe you have seen pic­tures of these " fireworks " of nature. Sometimes when a volcano erupts, a very large wall of melted rock moves down the side of a mountain. It looks like a " river of fire". Sometimes volcanoes ex­plode, throwing the melted rock and ashes high into the air. But where does this melted rock come from?
The earth is made up of many layers (層). The top layer that we see is called the crust. Under the crust are many layers of hard rock. But far, far beneath the crust the rock is so hot that it is soft. In some places it even melts. The melted rock is called magma. Sometimes the magma breaks out to the surface through cracks (裂縫) in the crust. These cracks are volcanoes.
Most people think of mountains when they think of volcanoes. But not every mountain is a volca­no. A volcano is simply the opening in the earth from which the magma escapes. The hot magma, or lava as it is called, cools and builds up on the surface of the earth. Over thousands of years, this pile of cooled lava can grow to be very, very big. For example, the highest mountain in Africa, Kilimanja­ro, is a volcano. It rises more than 16,000 feet above the ground around it.
8. The underlined word "erupts" means ______.
A. moves down   B. breaks away    C. builds up       D. suddenly throws out lava
9. Which words in the passage have the same meaning as "melted rock"?
A. volcano and crust                B. crust and hard rock
C. magma and lava                D. volcano and magma
10. Which is the correct order of the layers of the earth (beginning with the top layer)?
A. crust — hard rock — magma — soft rock
B. crust — hard rock — soft rock — magma
C. agma — soft rock — hard rock — crust
D. volcano — cracks — magma — crust
11. The best title of the passage should be______.
A. The Volcano        B. Kilimanjaro Volcano   C. The Mountains   D. The Melted Rock

We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸發(fā)) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
59. According to the passage, the root cause for weather changes on the Earth is ______.
A. the atmosphere surrounding the Earth                         
B. water from oceans and lakes
C. energy from the Sun                   
D. greenhouse gases in the sky
60. Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.
A. absorbed by the clouds in the lower atmosphere
B. reflected by the gases in the upper atmosphere
C. lost in the upper and lower atmosphere
D. used to evaporate water from the oceans and lakes
61. We learn from the passage that _______________.
A. all living things on the Earth depend on the Sun for their food
B. a forest looks dark in winter because it absorbs solar energy
C. only 0.023% of the energy from the Sun is made use of on the Earth
D. greenhouse gases allow heat energy to escape from the Earth’s surface

Federal regulators Wednesday approved a plan to create a nationwide emergency alert (警報) system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates (估計) more than 48 billions text messages are sent each month.
The plan comes from the Warning Alter and Response Network Act, a 2006 federal law that requires improvement to the nation’s emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alter the public about emergencies.
“The ability to deliver accurate and timely warning and alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alter system by carriers — telecommunication companies — is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alters.
There would be three types of messages, according to the rules.
The first would be a national alter from the president, likely involving  a terrorists attack or natural disaster. The second would involve “approaching threats,” which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (綁架)emergencies, or so-called Amber Alerts.
The service could be in place by 2010.
61. What is the purpose of the approval plan?
A. To warn people of emergencies via message.
B. To popularize the use of cell phone.
C. To estimate the monthly number of messages.
D. To promote the wireless industry.
62. The improvement to the present system is in the charge of ______.
A. CTLA.   B. the Warning Alert and Response Network
C. FCC    D. federal regulators
63. The carriers’ participation in the system is determined by _______.
A. the US federal government  B. mobile phone users
C. the carriers themselves       D. the law of the United States
64. Which of the following is true of cell phone users?
They must accept the alert service. 
B. They may enjoy the alert service for free.
C. They must send the alerts to others.
D. They may choose the types of messages.
65. An alert message will NOT be sent if __________.
A. a child loses his way         B. a university shooting happens
C. a natural disaster happens   D, a terrorist attack occurs
66. Which of the following would be the best title for the test?
A. Cell Phone Alerts Protecting Students
B. Cell Phone Alerts by Wireless Industry
C. Cell Phone Alerts Natural Disasters
D. Cell Phone Alerts Coming Soon

When a magazine for high school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate（旋轉）so they could follow the sun to take maximum advantage of its light and heat. Walls would “give light” and “change color with the push of a button.” Food would be replaced by pills. School would be taught by electrical impulse（電脈沖）while we sleep. Cars would have radar（雷達）. Does this sound like the year 2000? Actually, this article was written in 1958 and the question was, “what will life be like in 1978?
The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accuately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on Cities wrote: Cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in “airbuses”, large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents “almost unheard of”. Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was “The city of 1982”.
If the professionals sometimes sound like high school students, it’s probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accuate, and generally it is. But there have been some big mistakes in the field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers.
One forecaster knew that predictions about the future would always be subject to significant error. In 1957, H.J. Rand of the Rad corporation was asked about the year 2000, “Only one thing is certain,” he answered. “Children born today will have reached the age of 43.”
小題1:How many examples does the author offer to describe the future life?
A．ThreeB．FourC．FiveD．Six
小題2:The high school students’ answers to “What would life be like in 1978?” sound __________.
A．accurateB．imaginativeC．correctD．foolish
小題3:In the second paragraph, the writer gives examples to show _________.
A．predicting about the future can be done in a humorous way
B．no predictions are based on careful research
C．experts are always better than others in figuring out what the future will be like
D．forecasting the future is not an easy job even for experts in this field
小題4:From the third paragraph we can learn that _________.
A．economy forecasting is rather a new field
B．experts began economy forecasting in 1929
C．the predictions about economic situation caused the investors to lose lots of money
D．good, accurate forecasting helped the stock market overcome the difficulties
小題5:H.J.Rand’s prediction about the year 2000 shows that ________.
A．it is easy to figure out in advance what will happen
B．it is difficult to figure out in advance what will happen
C．only professionals can figure out in advance what will happen
D．very few professionals figure out in advance what will happen
