General Electric introduces the iron of tomorrow. The iron can clean itself. Inside where irons get dirty. Because it cleans itself each and every time you empty it.How? With a push of a magic blue button.
The magic blue button.The first thing you’ll notice that’s different about this iron is the blue button on the side. It’s marked “Self Clean”. Push this blue button, and you can wash out loose mineral deposits that remain and block up inside. Push this button, and you’ve made life a lot easier.
Less chance of brown spotsSure, Self Cleaning Iron is going to cut down on brown spots. (Those ugly spots that happen on nice, cleanly pressed clothes.) Because a Self Cleaning Iron becomes clean each time you press that magic blue button.Steams much longerCommon sense tells you that if you’ve an iron that blocks less often it has to stay younger for a long period of time. In other words, it steams much longer. That’s another joy of owning General Electric’s Self Cleaning Iron.What does it mean to youToday you are doing so much more than just running a house and running after the kids. You’re working. You’re going to school. It’s all part of your lifestyle. The iron can change that lifestyle. By giving you less trouble before you iron. If we can make it easier for you to be a better wife, a better mother, a better housemaker, we want to. The new Self Cleaning Iron is another one of Home-Makers from General Electric.

举一反三
The earth is made up of many layers (层). 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 (裂缝) 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
Later，they found it was easier to tell the exact time by looking at the shadows.Thus， the sundial(日晷) was invented.
The sundial proved a useful timepiece in sunny weather. However，another typc of timepiece was necessary for cloudy weather and nigh time.A sand glass was another common measurer of time.Two glass bottles were connected by a very small opening. The top bottle was filled with sand，which dropped slowly into the botton one in a certain period of time.Hour glasses were widely used then.Three—minute sand glasses are still used in many homes to time the boiling of eggs.
The real ancestor of modern clocks was the water clock.In China ,an early water clock was made up of several bowls. Water trickled(滴) from one bowl to another to keep the clock going. Visitors to the Beijing Palace Museum can still see the old water clocks showing the time there.
In the Middle Ages a wateless clock was invented which worked by means of weights. To keep the weight falling at the same speed，a system of wheels was invented. The pendulum(钟摆) was soon developed to control the speed of the wheels. Thus the modern form of clock came into being.
9.Which of the following is the correct picturr of a sand glass?
A. B. C. D.10.Three minute sand glasses are still used in many homes .
A.to boil eggs B.to measure the time of boiling eggs
C.to hold the boiled eggs D.to have eggs boiled
11.If you visit Beijing Palace Museum, you .
A.will see the old water clocks broken
B.will find the time shown by the old water clocks is wrong
C.can find the old water clocks still telling the time there
D.will find the old water clocks have gone
12.In the Middle Ages the weight falling speed of a clock was kept by .
A.several bowls B.a system of wheels
C.a system of pendulum D.several springs
This discovery was chosen by Science, one of the world’s leading magazines, as the most important scientific achievement of 2004 last Friday.
“This little, wheeled, one-armed box went around another planet and has done something no human has ever managed,” according to Science. “It has discovered another place in the universe where life could once have existed.”
“Although we still can’t say that life could have existed in this environment, it is now certain that there was water on Mars,” said Steve Squyres, one of the scientists working on the Mars mission. The evidence comes from pictures and chemical readings taken by Opportunity. It includes marks on rocks like those caused by flowing water on Earth and salty chemicals like those found in dried-out sea-beds. Scientists said the new evidence proved beyond doubt that water has been existed on Mars. But it is still unknown whether the water on Mars was like an ocean or just ice.
While Opportunity has not found any signs of life, the presence of water means life is possible. “In everything we know about life on Earth, there is no example without liquid water,” Squyres said. “So water is important for the search for life on Mars.”
Researchers agree that a future mission (任务) should bring back physical samples (样品). But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth. “The problem here is how to get the samples back,” Squyres replied. “I think it is our responsibility to limit any risk.”
1. ________ prove that water existed on Mars.
A. The physical samples with salty chemicals B. The marks on rocks and salty chemicals
C. Scientific achievements of 2004 D. Creatures from Mars
2. Which of the following is true according to the text?
A. It is now certain that there was water on Mars.
B. The water on Mars was like an ocean.
C. Evidence of life on Mars has been found.
D. Search for life on Mars is a great risk to humans.
3. How did scientists draw the conclusion that there was water on Mars?
A. The world’s leading magazine has announced the fact.
B. Scientists have taken many pictures and chemical readings on the Mars.
C. Astronauts have got some rocks from Mars.
D. Scientists have made a study of the pictures and readings sent back by Mars detector.
4. It can be inferred that, if the creatures from Mars came to Earth, ________.
A. they would be kind to humans B. they would be cruel to humans
C. they would be a great danger to Earth
D. it would be hard to say whether it would be a good news or bad news
In his first State of Union message since taking office a year ago, President George Bush promised to wipe out illiteracy(文盲) in the next decade and declared that“by the year 2008, U.S students must be first in the world in math and science achievements. ” They have a long way to go. American students were placed 14th in a recent general science test conducted in 16 countries. In a separate survey of chemistry students, the United States came 12 out of 14. In a mathematics test, they were last. According to Bush, there are 17 million illiterates in this country of 245 million people. Other estimates put the number as high as 23 million. In percentage terms, that ranks the United States alongside Niearague and below Cuba. “This nation,”Bush said in his State of the Union address, “will not accept anything but excellent in education.” Bush, who has declared himself “Education president”, and senior officals of his administration are warning that the United States will be unable to compete in the world without an educated workforce.
How to increase educational standards is a matter of debate in a country whose schools have no uniform national curriculum and are subject to a confusing variety of state and local controls. Most experts think that the problem lies at the elementary and high school"levels rather than with universities-but even their graduates show huge gaps in general knowledge. Among the root causes most frequently mentioned in education debates is the low respect in which U.S. society holds teachers-in contrast to Japan and Germany. In Japan teaching is a profession of high prestige(威望) and high pay. In the United States teachers are near the bottom of the society.
5.By“the United States came 12 out of 14”(Para. 2), the author means .
A.the United States ranked 12th not 14th in the chemistry test
B.the United States ranked 12th in the chemistry test conducted by 14 countries
C.the United States progressed from 14th to 12th in the chemistry test
D.the United States ranked 12th in chemistry test and 14th in general science test
6.The cause of low educational level in America include the following EXCEPT that .
A.some problems exist in primary and secondary education
B.society keeps teachers in low respect
C.America pays more attention to economy instead of education
D.America has no uniform national courses
7.Which of the following statements can be inferred from the passage?
A.President Bush carried out his promise made in his first State of Union message.
B.The education in Japan and Germany is in higher level.
C.According to Bush, the number of illiterates accounts for 9% of the total.
D.Teachers in the United States enjoy good treatment and great respect.
8.Which of the following is the right order of the least-first of the percent of illiterates?
A.Germany, Cuba, Nicaragua. B.Germany, Nicaragua, Cuba.
C.Nicaragua, Japan, Cuba. D.Cuba, Japan, Nicaragua.
The generation of electricity through nuclear power came directly from the original work on the atom bomb. Because of the increase in demand for energy and the possibility of decreasing supplies of oil and natural gas, the interest in electricity has increased. One of the by-products of nuclear power stations is plutonium (钸) produced from unclear fuel: plutonium is ingredient (成分) in bomb-making. It means that there are far more opportunities for the manufacture of bombs.
This brings the problem to a full circle again. How can something so valuable and useful be controlled so that it works for the benefit and not the destruction of man?
9. The effects of dropping the first atomic bomb ________.
A. are not over B. may go on forever
C. could last much longer D. will not be over in the near future
10. The writer says that enough atomic bombs have already been manufactured to ________.
A. wipe out Japan B. last forever
C. act as a peace-keeping device D. destroy all living things
11. The advantage of less developed countries being able to make atomic devices is that it ______.
A. gives them more opportunities for work B. will help poor countries to become richer
C. will enable them to make better explosives D. will be of great value to them
12. The second paragraph tells us that the increased demand for electricity today ________.
A. has led to the decrease in supplies of oil
B. means that more countries are interested in nuclear power
C. has increased the risk of accidental explosions
D. has increased the very means of producing more atomic bombs
