In only two decades Asian Americans have become the fastest-growing US minority．As their children began moving up through the nation’s schools，it became clear that a new kind of culture was coming out．Their achievements are made in the nation’s best universities，where mathematics，science and engineering departments have taken on a decidedly Asian character.This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promise of a good job after college．Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively(客观)．And the money spent on education is more immediately returned in something like engineering than with an arts degree．
Most Asian-American students owe their success to the influence of parents who are determined that their children should 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，such as family value，the importance of education and so on that lead to their success.
Both explanations for academic success worry Asian Americans because of fears that they could cause the native Americans’unhappiness．Many can remember when Chinese,Japanese and Filipino immigrants(移民)were unequally treated because of social separation．Indeed，it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.Few Asian-American students major in human sciences mainly because .
| A．they are afraid they might meet with unfair judgement in these areas |
| B．there is a wide difference between Asian and Western cultures |
| C．they know little about American cultures and Western cultures |
| D．their English is not good enough |
Asian-Americans prefer something like engineering to an arts degree because________.
| A．people majoring in engineering are respected |
| B．people with an arts degree are looked down upon |
| C．they can’t find a job with an arts degree |
| D．they can earn more money after graduation |
While making great achievements at college，Asian-American students________.
| A．are afraid that their academic successes take on a strong Asian character |
| B．still worry about unfair treatment in society |
| C．generally feel it a shame to have to depend on their parents |
| D．feel they are mistreated because of limited knowledge of English |
According to the passage，the major factors determining the success of Asian-Americans are .
| A．Asian culture and the American educational system |
| B．Asian culture and a solid base in basic mathematics |
| C．hard work and parental help |
| D．hard work and a limited knowledge of English |
Wind is the great maker of waves. There are exceptions, such as the tidal waves, sometimes produces by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point)to crest (high point),and it has length—the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same— for all depend upon the depth of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so, for if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.
If we want to find the speed of a wave, we may use the following way:
Speeding="Wavelength×Frequency"
Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.
41.What causes waves according to the passage?
Earthquakes and nothing else. B. Wind and volcanos.
C. Wind and earthquakes. D. Wind and water.
42.Which of the following is true according to the text?
A. The water of a wave moves away across the sea.
B. The water of a wave remains almost in the same place.
C. The water of a wave goes with the passing of the wave.
D. The length of a wave means the distance between crest and trough.
43.The underlined word “succeeding” means__________.
A. reaching an aim B. doing well C. following after D. taking place
44.If the speed of wave 1 is 100 cm/s, and its frequency 10;and the frequency of wave 2 is 300,while its speed is twice that of wave 1.Which of the following is true?
A. The wave-lengths of the two are equal.
B. The wave-length of wave 1 is 10 times longer than that of Wave 2.
C. The wave-length of wave 2 is longer than that of wave 1.
D. The wave-length of wave 1 is longer than that of wave 2.

More and more often we heard of people talking about Karaoke（卡拉OK）。 But what on earth it is about， still remains a question for many people. Karaoke is a sort of acoustic equipment which was invented in Japan around the middle of the 1970's. It means "a band without people" in Japanese. In fact， it is just a music tape without words. This equipment first appeared in some public houses and snack bars， and mainly for the customers to enjoy themselves. Most of the music in Karaoke was popular music. Therefore， at times， when anyone felt like it， he might sing songs to the accompaniment of the music that came from the equipment. Shortly after its invention， Karaoke was spread to the whole world. It was introduced to China and was welcomed by many people. Although you are not a good singer， or even sometimes you may sing out of tune， you can always enjoy yourself by singing Karaoke.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air， water and sunlight. Animals and man cannot make food from air， water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you， you will find that there are two kinds of plants： flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two， three or four， and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.
