文档简介
第一单元Todays trumpet (喇叭,小号) is one of the worlds oldest instruments. It is the result of many centuries of development. Although it looks nothing like the ones of old days, there are many similarities. All trumpets are hollow tubes (管) They are all blown. And they all use the players lips to produce their basic sound. The trumpet developed as players and makers worked to improve its design, size, shape, material, and method of construction. They wanted to create an instrument that would produce a beautiful and attractive tone, enable the performer to play all the notes of the scale, extend the range higher and lower, make it possible to play more difficult music, and in general, be easier to play well. The remarkable way in which the modern trumpet achieves these goals is a measure of the success of all those who struggled to perfect this magnificent instrument. The trumpet is actually the leading member of an entire family of related instruments. There are trumpets of several different sizes, and in several different keys. There are cornets (短号), bugles (军号), flugelhorns (粗管短号), and a number of others that are all similar to the trumpet in the way they are made and played. The trumpet family is much more than a group of related instruments that can stir one with their sound, or narrow tubes of metal capable of producing a variety of musical sounds. It is a link to many different periods of history and to people of many cultures. From the use of trumpets in ancient religious ceremonies to the part they play in modern rock bands, the trumpet family of instruments has much to tell about civilization and its development. 1.How do trumpets all resemble each other?(C)A.

The links between different people.Language is a way to communicate with each other. We started to learn language when we were born. However, people are used to speaking their native language, so immigrants are having many problems between the first generation and the second generation because they dont have the same native language. Also, the second generation is losing their identity. Especially in America, there are many immigrants that came from different countries to succeed in the States. Because they suffer in lots of areas such as getting a job and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more successful. Because of this situation, their children are losing their ethnic identity and, even more, they are ignoring their parents whose English is not very good. I think most immigrants are trying to preserve their native language in their new country, but this doesnt help very much in getting a good job. My aunt didnt teach Korean to her children in order to help them succeed in the US; she did so, hopefully, to help them establish a Korean identity. Though the second generation is born in the new country, they often get confused about their identity. My cousins told me that when they visited Korea a few years ago, they felt different from other Koreans. They could even feel it just strolling around the street because they wore different clothes. We must realize that language is important and valuable for many reasons. Immigrants should make an effort not to be ignored by their children and to make their children understand their heritage by teaching them the parents language. This is important in helping the second generation establish their identity. 6.Which people are having trouble with language?(D)A. Natives.B. People of the 2nd generation.C. People when born.D. Immigrants.7.Why are children ignoring their parents?(C)A. Children have lost their identity.B. Parents cause children to suffer.C. They speak different languages.D.

It is much more than just a great workout. You get to be outside of the confines of a gym and be together with nature. You breathe in the fresh, clean air while the city life you endured all week just fades away. You are suddenly transported somewhere else. You are suddenly in a place where you can appreciate the untouched, simplistic beauty of nature. The trees are green, the wild flowers are growing and the woods are filled with activity. Once you experience it, youre hooked. Whether hiking in the deserts of Arizona or the mountains of Alberta, you suddenly realize you are not alone and there is something much bigger at work. There is a realization that life is precious and you think deeply about your life. Another wonderful part of hiking is that you can participate at any level and it is, for the most part, free. It is a great way to escape the rat race, even during the week. If you have any problems you need to solve, hiking is really good for clearing your head and removing stress. If hiking sounds intimidating to you, it is essentially walking on a whole new level. Experts have spoken about the benefits of walking for years. Walking doesnt stress your legs as much as running and countless studies agree walking leads to weight loss and better health. It is good for your heart, reduces illness and has even been shown to enhance your thinking. So why wouldnt you want to do it? 1.What makes hiking different from other forms of exercise?(D)A. It is a great workout.B. It is a summertime activity.C. It is an activity that slows breathing.D. It is an exercise that is done outside.2.What disappears for someone who is hiking?(C)A.

Precious things.3.Once you take up hiking in nature as something you do, you _B_.A. feel much bigger than beforeB. love it and want to do it oftenC. wish you lived outside of the cityD. look for new hiking places, like Arizona4.How do you feel after youve begun hiking?(D)A. Intimidated.B. Thoughtful.C. Lonely.D. Free from stress.5.How is running different than walking?(A)A. Running is harder on the legs.B. Running is better for weight loss.C. Running is good for a persons heart.D. Running is a cause for improved thinking.Whether or not vegetarianism should be advocated for adults, it is definitely unsatisfactory for growing children, who need more protein than they can get from vegetable sources. A lacto-vegetarian (part milk, part vegetable) diet, which includes milk and milk products such as cheese, can, however, be satisfactory as long as enough milk and milk products are consumed. Meat and cheese are the best sources of usable animal protein and next come milk, fish and eggs. Slow and careful cooking of meat makes it more digestible and assists in the breaking down of the protein content by the body. When cooking vegetables, however, the vitamins, and in particular the water-soluble (溶解于水的) Vitamin C, should not be lost through over-cooking. With fruit, vitamin loss is too small to be important, because the cooking water is normally eaten along with the fruit, and natural chemicals in the fruit help to hold in the vitamin C. Most nutrition (营养) experts today would recommend a balanced diet containing elements of all foods, largely because of our need for sufficient vitamins. Vitamins were first called added food factors when they were discovered in 1906. Most foods contain these other substances necessary for health, in addition to carbohydrates (碳水化合物), fats, minerals and water. The most common deficiency in Western diets today is lack of vitamins. The answer is variety in food. A well-balanced diet, having sufficient amounts of milk, fruit, vegetables, eggs, and meat, fish or chicken (i.e. any good protein source), usually provides the minimum daily requirement of all the vitamins. 6.Vegetarianism is not suitable for growing children because they _A_.A. need more protein than vegetables can supplyB. cannot digest vegetablesC. use more energy than adultsD. cannot easily digest milk and milk products7.A lacto-vegetarian can eat _B_.A. cheese, beef, and nutsB. carrots, milk, and riceC. potatoes, ham, apples, and beansD. tomatoes, bacon, and oranges8.Slow and careful cooking of meat _C_.A. preserves the vitaminsB. breaks down the vitaminsC. makes it easier to digestD. reduces the protein content9.The reason why the vitamin loss in fruit is not important is that _D_.A. vitamins in fruit are not removed by cookingB. chemicals are often used in the cooking of fruitC. fruit has too few vitamins to be important to ones dietD. the cooking water is usually eaten along with the fruit10.Most nutrition experts today believe the food we eat should contain _C_.A. more meat than vegetablesB. more vegetables than meatC. fruit, cereals and fish as well as meat and vegetablesD. as many different kinds of vegetables as possibleEngineers of the Woods In the forests of North America, where the winters are often long and cold, small lakes can be found along the streams. Sometimes these lakes are natural, sometimes they are man-made, and sometimes they are the constructions of beavers (海狸). You can tell a beaver lake by its dam. To make the dams, the beavers lay sticks and branches on top of each other to form an effective barrier against the water of the stream. Near the dam the beavers lay sticks and branches. Usually this barrier is similar to a small island in a lake. This is the house where a beaver family spends the winter, protecting themselves from enemies and from the cold. The beavers are able to keep dry in the center of the house, which is above water level. The beavers work hard to make their house. They cut down trees, gather branches and put them together with mud. Most of the summer is spent on this kind of work, but in winter the beavers work pays off. Their house protects them from bears as well as the cold. The beaver is related to animals such as rats and mice. The beaver, however, is much bigger than his relatives. An adult beaver may weigh more than 50 pounds, and his body may be about three feet long. His tail will add ten to twelve more inches to his length. His back feet are webbed, which help him swim rapidly. His front feet are similar to a pair of strong hands. With them he can carry wood and stones. His eyes, nose and ears are small, but he has two huge front teeth. These teeth are always growing, and he must keep them sharp by constant use. The teeth of an adult beaver are yellow from the bark of trees that he bites. Men attach great value to the beaver because beavers can be sold to make expensive clothing. Beavers have almost disappeared from Europe because trappers (设阱捕兽者) have killed so many of them. Beavers might easily have become extinct in America, too, but laws were passed to protect them before they were all killed. The beaver likes family life, and lives with the same mate all his life. Several youngusually two to fiveare born every year. The little beavers stay with their parents for two years before mating and setting out on their own. They share the work of building dams, constructing homes and raising the young. When there are too many beavers in one place, some of them will group together in another place. They usually choose a spot near some fairly deep lake or river, where there are trees. The bark of trees is eaten as food. Then the wood is used for building. Sometimes the lodges are built on the bank of the water, but usually they are built on an island in the water. If there is no island already there, the beavers make one by piling sticks and mud on the bed of the river until the top is a few inches above the level of the water. The top is carpeted with small pieces of wood leaves. A roof of sticks and lots of mud is then built over this floor. Food for the winter is taken to the lodge before the weather gets too cold. Some of itthe larger piecesis stored on the bottom of the lake or river, near the entrance to a tunnel leading up to the lodge. There are sometimes several such entrances, under the surface of the water. Wood that is kept under water may be stuck in the mud, or weighted down with stones. Beavers prefer to work at night. One beaver, on a single night, can cut down a tree that is eight inches around. After cutting down the tree, the beaver cuts the trunk into pieces that can be carried. He uses these as the base for the dam. A small dam may be enlarged after several years, in order to flood a large surface and provide living space for more beavers. Under favorable conditions, a dam may last for a hundred years or more. Naturally, other animals use these dams as bridges, forcing the beavers to keep the dams in good repair. The dams must be strong enough to hold up against the pressure of ice in spring and sometimes, holes are made by the beavers, after heavy rains, to allow excess water to run off. Another type of work beavers do is canal digging. When they have used up the good trees near their home, they must bring more wood from farther away. To accomplish this, they may dig a canal (运河) to float the trees to the place where they are needed. Beaver dams help people because they prevent floods and bring water to farms. It is fortunate that these animals have not been allowed to disappear completely. 1.The stick and branch dams made by beavers are similar to _B_.A. houses where people spend the winterB. small islands in a lakeC. barriers against the water of the streamD. dams that are man-made2.Beavers spend most of the summer _B_.A. hiding from bearsB. making their houseC. keeping coldD. looking for mice and rats3.To help it swim quickly, a beaver has _D_.A. small earsB. strong front feetC. a long tailD. webbed back feet4._C_ have (has) protected beavers from becoming extinct.A.
