Stephen Hawking was born in Oxford, England, on January 8, 1942. At the age of 17, he entered University College, Oxford. He wanted to study mathematics, but took up the study of physics when math was unavailable. He received a Ph.D. in physics despite being diagnosed (诊断) with Ameliotrophic Lateral Sclerosis (肌萎缩性脊髓侧索硬化症) while at Oxford in 1963. In 1985 he became ill with pneumonia (肺炎), and since then has required 24-hour nursing. Dr. Hawking’s determination, along with the help of his family and associates, has allowed him to continue to work. In 1970 he began studying black holes. His research led him to predict that black holes send out radiation in the X-ray to gamma-ray(伽马射线) range of the spectrum (光谱). In the 1980s he returned to an earlier interest, the origins of the universe. He has co-authored many publications, such as 300 Years of Gravity and The Large Scale Structure of Space time. Dr. Hawking has also written books such as A Brief History of Time, Black Holes and Baby Universes and other Essays, The Universe in a Nutshell and others. He continues to give lectures, despite having been unable to speak since 1985, with the aid of a speech synthesizer (合成器) and a portable computer. He currently holds Isaac Newton’s chair as the Lucasian Professor of Mathematics at Cambridge University in England.Hawking went to University College, Oxford, in order to _____.

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.
