It is sometimes reported that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified(不明的)Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe.Some have been explained in scientific ways. Others have never been explained.
Here is an account of UFOs from a report.
Dennis Bardens,who wrote an article,tells us that he once saw a UFO himself.He was having dinner one night with a friend near Tripoli(的黎波里),Libya(利比亚),and after dinner the two men walked across a yard to his room to look at some papers.Bardens noticed that the moon looked strange that night.
“It wasn"t the moon,”was the reply.
They watched the light and saw that it was moving.It seemed to be an object rather like a big plate.In some ways it looked like smoke with a light on it,but it wasn"t smoke because it didn"t change its shape.It was moving in a regular way.That is to say,it didn"t go suddenly faster or more slowly,and it didn"t go higher or lower.So the two men decided that there must be men in it.
When it came nearer to Libya,Bardens said that he felt eyes looking at him.He was being watched in the darkness.
When it was nearer,they noticed that the bottom parts were brighter than the top.The bottom was yellow and the top was red.Then the object suddenly turned away and left Libya,moving very fast.
On a later day Bardens talked to other people about it,and he found some who had seen it.They all described(描述)it in the same way.Could they all the mistaken?
60.The UFOs are______.
A.flying high up in the sky B.strange flying objects
C.difficult to believe D.very interested
61.A UFO was seen one night______.
A.when they were walking across a yard to Bardens" room
B.while they were looking at the light
C.when Bardens noticed the moon appearing strange
D.while they were having dinner
62.The UFO looked like______.
A.smoke B.light
C.a moving object D.a large plate
63.When the UFO came nearer to Libya,______.
A.it disappeared all at once
B.it suddenly turned away and left
C.it was watched in the darkness
D.Bardens was looking at it
答案
解析
61. 从“……and after dinner the two men walked across a yard to his room to look at some papers.Bardens noticed that the moon looked strange that night.”可以推断A为看到UFO的时间。B项说“他们在看着灯光的同时,看到了UFO”,这是不对的。当他们看到UFO时,Bardens误以为那是月亮,其实那个奇怪的月亮“就是UFO”,因此C也不对。D项内容与“……and after dinner……”中的时间不相符。
62. UFO看起来好像个大碟子(盘子),又像带着一盏灯的烟,但又不是烟。由此,可确定D正确。
63. 当UFO接近利比亚时,突然掉头离开利比亚。A项说“UFO一下子消失了”不对。从“…Bardens said that he felt eyes looking at him.He was being watched in the darkness.”可判断出C项不正确(在黑暗中被注视的是Bardens而非UFO)。

The new lightweight(轻量的) 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(使均匀,使匀质) milk and sterilizing(使无菌) 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.
D. Because the waves can clean the paint.
2. What properties does ultrasound wave have?
A. Homogenizes and sterilizes the milk. B. Mix materials and break droplets.
C. Kill germs and sterilize milk. D. Move liquids quickly.
3. What exists in the raw milk?
A. Little drops of butter fat. B. Small holes.
C. Fat droplets and germs. D. Chemicals.
4. Where is ultrasound wave not used?
A. In the paint manufacture. B. In the shop mixing bread flour.
C. In the film-making company. D. In the dairy industry.

The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rock. At the same time, the land was rising. Today the canyon is 1.5 kilometers and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than 1 billion years old. The width varies from about 200 meters to 29 kilometers across. The rim or top of the canyon is about 2,300 meters above sea level on the South Rim, and about 3,000 meters on the other side. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is dry desert country. The North Rim has tall forests.
The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange colors of the rocks are especially clear and bright. In winter, the canyon is partly covered with snow.
The view from the South Rim of the Grand Canyon is the best. Most visitors come here and stay in campgrounds or hotels. Every point along the canyon’s edge offers a different view.
The North rim of the Canyon is quieter. It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navado Indian lands, and a colorful pink desert called “The Painted Desert”.

Most AsianAmerican students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education.
Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese,Japanese and Filipino immigrants were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

B.they are afraid they might meet with unfair judgment in these areas
