Before going outside in the morning, many of us check a window thermometer (温度计) for the
temperature. This helps us decide what to wear. 1_____. We want our food to be a certain coldness
in the refrigerator. We want it a certain hotness in the oven. If we don"t feel well, we use a thermometer
to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in
the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the
Fahrenheit scale. But most other countries use the Centigrade scale. Both systems use the freezing and
boiling points of water as their guide. 2_____.
The most common kind of thermometer is made with mercury (水银) inside a clear glass tube. As
mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts (收缩). That is
why on hot days the mercury line is high in the glass tube. 3_____.
First. Take a clear glass juice bottle that has a cap; fill the bottle with coloured water. Tap a hole in
the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw
(吸管) through the nail hole. 4_____.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the
water lever easily. 5_____.
As the temperature goes down, the water will contract, and the lever in the straw will come down.
Perhaps you will want to keep a record of the water lever in the straw each morning for a week. |
A. We use and depend on thermometers to measure the temperature of many other things in our daily
lives.
B. Thermometers measure temperature, by using materials that change in the same way when they are
heated or cooled.
C. Now that you know this rule you can make a thermometer of your own that will work.
D. The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise
even higher.
E. They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212
degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.
F. Take wax (you may use an old candle if you have one) and melt some of it right where the straw is
struck into the cap to seal (把..粘住) them together.
G. People use thermometers which are made by themselves when travelling around the world. |

We are all called upon to make a speech at some point in life, but most of us don"t do a very good job.
This article gives some suggestions on how to give an effective speech.
So, you have to give a speech-and you"re terrified. You get nervous, you forget what you want to say,
you stumble over words, you talk too long, and you bore your audience. Later you think, "Thank goodness,
it"s over. I"m just no good at public speaking. I hope I never have to do that again."
Cheer up! It doesn"t have to be that bad. Here are some simple steps to take the pain out of speech
making. Ask yourself the purpose of your speech. What is the occasion? Why are you speaking? Then,
gather as many facts as you can on your subject. Spend plenty of time doing your research. Then spend
plenty of time organizing your material so that your speech is clear and easy to follow. Use as many examples
as possible, and use pictures, charts, and graphs if they will help you make your points more clearly. Never
forget your audience. Don"t talk over their heads, and don"t talk down to them. Treat your audience with
respect. They will appreciate your thoughtfulness.
Just remember: be prepared. Know your subject, your audience, and the occasion. Be brief. Say what you
have to say and then stop. And be yourself. Let your personality come through so that you make person-to-
person contact with your audience.
If you follow these simple steps, you"ll see that you don"t have to be afraid of public speaking. In fact,
you may find the experience so enjoyable that you volunteer to make more speeches! You"re not convinced
yet? Give it a try and see what happens. |

Solar energy for your home is coming. It can help you as a single home owner. It can help the whole
country as well. Whether or not solar energy can save your money depends on many things. Where you
live is one factor and the type of home you have is another. Things like insulation (绝缘材料), present
energy costs, and the type of system you buy are added factors.
Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very
limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature
will say that"s all. The only way we can delay hearing those words is by starting to save energy now and
by using other sources, like the sun.
We won"t have to worry about the sun"s running out of energy for another several billion years or so.
Besides, the sun doesn"t offer as many problems as other energy sources. For example, fossil fuel (矿物
燃料) adds to already high pollution levels. With solar energy, we will still need sources of energy, but we
won"t need as much. That means we can cut down on our pollution problems. With all these good points,
why don"t we use more solar power? There are many reasons for this. The biggest reason is money. Until
now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy.
All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say
that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But
new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being
rationed (限量供应). Solar energy is now in its infancy (初期). It could soon grow to become a major part
of our nation"s energy supply. |
| 1. What"s this passage mainly about? |
| [ ] |
A. Something about solar energy and pollution.
B. Solar energy.
C. Energy and pollution.
D. Energy and money. |
| 2. Solar energy can help us _____. |
| [ ] |
A. escape punishment from nature
B. become home owners
C. get rid of present energy
D. save our precious fuel |
| 3. The sun is an endless source of energy, and it will not run out of energy for _____. |
| [ ] |
A. several million years
B. several hundred years
C. several billion years
D. several thousand years |
| 4. Which of the following statements is TRUE? |
| [ ] |
A. Energy from coal would not pollute our living environment.
B. Energy from natural gas would not pollute our living environment.
C. Energy from the sun would not pollute our living environment.
D. Energy from oil would not pollute our living environment. |
| 5. Solar energy is now in its infancy, _____. |
| [ ] |
A. but in the future it will become an important part of our nation"s energy supply
B. so we will build more power plants
C. and the supply of electricity will be rationed throughout the country
D. so we don"t need it |

Ten Chinese 3 , enjoying a holiday in a National Forest Park, were driving down a road. As their bus
turned a corner, the men were suddenly 4 by what they saw. Three 5 animals, covered with long
black hair, were crossing the road. On seeing the animal, the engineers immediately stopped and 6 them.

D. correct | | 阅读理解。 | Before a new type of airplane goes into service, every part of it is tested again and again. But there are two
tests that are more important than all the others.
The first is called the "tank test". A modern airplane must fly very high in the sky. Air must be pumped into
the plane so that the passengers can breathe. The metal structure (结构) of the plane has to be very strong for
this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure
(压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail,
the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or
container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it
is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank
as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made
stronger.
The most dangerous test happens when the new plane is going through test flights in the air. The test pilot
must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to
fall like a stone. It is the pilot"s job to find out how he can get control of the plane again. These two tests are
examples of how planes are made safe before they ever carry passengers. | | 1. By doing the "tank test", the engineers can find out _____. | | [ ] | A. the power of the airplane engines
B. the amount of air in the plane
C. the strength of the plane structure
D. the pressure inside and outside the plane | | 2. What will happen to the plane under the "tank test"? | | [ ] | A. It will be tested by pilots.
B. It will be broken.
C. It will be made stronger.
D. It will be filled with water. | | 3. According to the text, why are test flights most dangerous? | | [ ] | A. Too much air may get into the plane.
B. The plane may explode in the air.
C. The pilot may lose control of the plane.
D. The engines may be damaged. | | 4. What might be the most suitable title for the text? | | [ ] | A. How Airplanes Are Made and Tested
B. Two Important Tests on Airplanes
C. The Importance of Flying Safely
D. The Danger of Testing Airplanes | | 阅读理解。 | Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This
kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for
years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary (暂时的). This is the most common type. It usually disappears
quickly and does not require any special attention. The second kind, situational loneliness, is a natural result
of a particular situation-for example, a family problem, the death of a loved one, or moving to a new place.
Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually
does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type,
chronic (长期的) loneliness usually lasts more than two years and has no specific cause. People who
experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many
chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy
and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart
disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can
be a very sad, and sometimes dangerous condition. | | 1. How would you treat temporary loneliness according to the passage? | | [ ] | A. Talk to friends.
B. Just ignore it.
C. Go to see a doctor.
D. Ask your teachers for guidance. | | 2. "It" in the last sentence of the second paragraph refers to _____. | | [ ] | A. temporary loneliness
B. situational loneliness
C. a new place
D. sleeplessness | | 3. Why do psychologists want to help chronically lonely people? | | [ ] | A. Chronic loneliness can cause family problems.
B. Chronic loneliness can cause serious illness.
C. Chronic loneliness can not be overcome.
D. Such people are harmful to society. | | 4. What is the best title for the passage? | | [ ] | A. Three kinds of loneliness
B. Loneliness and Diseases
C. Loneliness and Social Contacts
D. Chronic Loneliness | 最新试题
