听力原文： Each day every person in the United States throws away more than five pounds of garbage. There is more garbage now than ever before and most of it is made up of the packages and cans in which we buy our food. The traditional way of getting rid of solid wastes is quickly becoming inadequate. Many cities are experimenting with newer ways of handling their growing piles of garbage. One of these new ways is "recycling" .Through recycling usable materials are taken out of garbage and made into something else. These usable parts of garbage are put through the cycle of going from a raw material to a finished product again.
In some cities a machine called Hydrapulper is being used to help recycle garbage. A Hydrapulper is like a huge mixing machine. The garbage is dropped onto a conveyor belt that feeds the machine. At the same time, water is pumped into the Hydrapulper. With a mixing action, the Hydrapulper throws out the heavy metal objects that can later be sold as waste metal, the rest of the garbage -- paper, food, plastic, rubber, glass, wood, leaves, and other items -- falls apart. The waste is then mixed with water and carried to another piece of equipment where glass, sand, and small pieces of metal are thrown out. With the Hydrapulper, up to 95 percent of the original garbage is made again useful. The rest is turned into furnace ash.

B: Yes, Professor Smith. We did.
S: Who's your lab partner, Bob？
B: Anne Wilson.
S: Well, Anne, can you and Bob go over the procedure for the class？
A: Sure. Firs(we put ten grams of crushed limestone in a bottle.
S: Anything special about the bottle？
B: It was a gas - collecting bottle with a one - hole stopper and bent glass tubing.
S: Very good. So you put the limestone in a gas - collecting bottle. Then what？
A: Then we poured in ten milligrams of hydrochloric acid, put on the stopper, and collected a bottle of carbon dioxide.
S: Right, What was the method of collection？
A: Water displacement.
S: Good.
A: Then, we lit a magnesium ribbon and put it in the bottle or carbon dioxide.
B: And carbon deposits began to form. on the bottom of the bottle, You see, we didn't have any problem with procedure.
A: Well, we had a little problem getting the magnesium ribbon to stay lit until we could get it into the bottle.
B: Okay. But we did it. The big problem was that we really didn't understand what happened. Did the magnesium combine with the oxygen in the carbon dioxide？
S: You have just answered your own question, Bob. The burning magnesium broke the carbon - oxygen bonds in the carbon dioxide, and then the oxygen combined with the magnesium to produce magnesium oxide.
A: And the carbon was freed to deposit itself on the bottle.
S: Exactly.
(23)
A．To discuss the results of the lab experiment.
B．To answer Bob' s question about the lab experiment.
C．To explain the method of collection by water displacement.
D．To prepare the students to do the lab experiment.

Of course, the truth is not so simple. This century, the work of cognitive(认知的) psychologists had illuminated the subtle forms o？ daily learning on which intellectual progress depends. Children were observed as they slowly grasped concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed (哄) into finding the total. Such studies have suggested that the basics of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers is itself far from innate.
What does the passage mainly discuss？
A．Trends in teaching mathematics to children.
B．The use of mathematics in child psychology.
C．The development of mathematical ability in children.
D．The fundamental concepts of mathematics that children must learn.

The basic theory of the greenhouse effect is quite simple. The earth's atmosphere consists【C8】______of oxygen and nitrogen,【C9】______there are small concentrations of various "greenhouse" gases-【C10】______carbon dioxide, water vapor, and methane(沼气)-- which play a very important role in【C11】______the planet's "heat balance". As their name suggests these gases have a similar effect on glass in a greenhouse: They let heat from the sun【C12】______, and keep it in.
The atmosphere is more or less transparent to the【C13】______solar radiation which warms the earth(ground or oceans)on which it falls.【C14】______it has been heated, the earth is warmer than space and gives【C15】______energy in the form. of in visible long-wave infrared radiation. This【C16】______for nighttime cooling. Greenhouse gases【C17】______some of this long-wave radiation, and reradiate it in the lower atmosphere.
The gases【C18】______act rather like a blanket by preventing some infrared radiation from leaving the earth-atmosphere system.【C19】______certain limits, the more greenhouse gases present, the more infrared radiation will become【C20】______, and the higher the surface temperature of the earth.

t the benefits of drinking Chinese tea for such things as losing weight and staying alert, but the following points may be something new to you.
Chrysanthemum (菊花) tea, made of white chrysanthemums, is a must for office workers in the closed environment with radiation contamination.The white chrysanthemum is regarded as an ideal herb in Traditional Chinese Medicines (TCMs), which can clear away the heat and poisonous substance accumulated in the body.According to TCMs, the herb can aid in the prevention of sore throat and promoting the reducing fever and cooling you down.It is also well known for making people more alert and is often used to waken them.Ancient Chinese adopted the tradition of drinking chrysanthemum wine in autumn, believing the wine would keep healthy.
Since it’s impossible to drink wine in the office, TCMs doctors highly recommend the chrysanthemum tea, instead, especially for those who suffer from serious radiation pollution or experience dry mouth.However, doctors suggest that weak people (who are very sensitive to cold and always have cold hands and feet) should take less chrysanthemum tea, which will make them feel colder.
Mugwort (艾蒿) tea is another popular tea in China.If you drink a lot of water before sleep, you’ll find yourself looking tired and pale the next morning, and you may feel as bad as you look.Mugwort tea will help you eliminate tiredness and recover your high spirits.Only several grams of mugwort are needed for a cup of tea.The tea may also be effective for weight loss.
Unlike other teas, the fruit tea is very flavorful with a light sweet taste.The small red berry is not a common fruit, but a kind of traditional Chinese medicine that helps maintain good eyesight and get rid of the waste in bodies.Watching the lovely cherries swelling up in the glass is an enjoyable process, and adding several white chrysanthemum in the tea can make the tea more tasty and beautiful.
46.Why is chrysanthemum tea necessary for the office workers in the closed environment？()
A.It can help reduce radiation pollution
B.It can provide the weak with warmth and energy
C.It may be effective for weight loss
D.It may be a treatment to cold in autumn
47.What is the medicinal use of the white chrysanthemum？()
A.It makes people stay in shape

Wedding Customs around the World
Wedding Ceremonies
A wedding is celebrated with some kind of ceremony almost everywhere in the world. The ceremonies vary greatly among different nations and different religions. But whatever the form. of a marriage ceremony, it serves the important purpose of announcing to the community that a male and a female have been joined in matrimony (婚姻) .
The wedding ceremony may be a religious one performed by a churchman. In Western societies it may be a civil ceremony performed by a civil official, such as a mayor or a judge. Or it may be only a couple's declaration, before witnesses, of their intention to marry. In some places a transfer of property makes a marriage binding. In other places blood is drawn from the hands of the bride and groom. The blood is mixed, sealing the union. Among some people the marriage rite consists only of' the bride and groom's sharing the same food.
Marriage is one of the seven important religious ceremonies of the Catholic Church. The marriage is held in a church with the service conducted by the priest in the language of the country. The couple stand at the altar (圣坛) . The priest asks each in turn, "Do you take name of partner here present for your lawful wife/husband, according to the rite of our Holy Mother, the Church？" In turn, each answers, "I do. ' They then repeat the marriage vows after the priest. The priest blesses the union: "In the name of the Father, and of the Son, and of the Holy Spirit. Amen." The priest sprinkles the couple with holy water and blesses the ring or rings.
Many traditional customs are observed at Jewish weddings, although they are not required by Jewish law. Usually the Jewish priest, the bride and groom, and their attendants stand under a decorated cover called a chupah (犹太教举行婚礼用的彩棚) . The present use of the chupah began during The Middle Ages among the Eastern European Jews. The Jewish priest conducts the service. During the ceremony the bride and groom make appropriate vows and take part in the ring ceremony. The Jewish priest blesses a cup of wine, from which the bride and groom beth drink. The Jewish priest talks to the couple about the sacredness of marriage and responsibilities of the bride and groom. After the Jewish priest has pronounced them man and wife, a wine glass is often placed on the floor. The groom steps on the glass and breaks it. Scholars disagree about the symbolism of the custom, but many believe that the breaking of the glass recalls the destruction of the temple in Jerusalem, reminding the couple that even at the moment of greatest joy, there may be sorrow.
The Muslim marriage is a civil and religious contract between the bride and groom. The religious ceremonies and celebrations vary with the customs of the country in which the marriage is held. People of wealth begin the celebrations two or three days before the wedding and continue for two or three days after. The bride is elaborately dressed in bright colors and wears her finest jewelry. The wedding takes place at the home of the bride. The service is performed by Muslim priest, before at least two male witnesses or one male and two female witnesses and then the vows are exchanged.
Wedding Customs
Many of the customs associated with wedding ceremonies are based on neither church nor civil law. They developed from wedding customs of earliest times and come from many lands.
The wearing of a bridal veil dates back to early Greek and Roman times. The veil was thought to conceal the bride from evil spirits. The veil is also believed to have been worn as an indication of the bride's innocence and purity.
The wedding ring is the most widely used symbol of marriage today, as it has been for centuries. The word "wedding" comes from the old English word "wed", which means "promise" or "pledge". During Anglo-Saxon times, a promise to marry was
A．A civil official.
B．A judge.
C．The bride's father.
D．A priest.
第10题
People appear to be born to compute. The numerical skills of children develop so early and so inexorably (坚定地) that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy--one plate, one knife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that they have placed five knives, five spoons, and five forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment.
Of course, the truth is not so simple. In this century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped--or, as the case might be, bumped into--concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have since demonstrated that young children, when asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed (说服) into finding the total. Such studies have suggested that the rudiments (基本原理) of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers--the idea of a oneness, a twoness, a threeness that applies to any class of objects and is prerequisite (先决条件) for doing anything more mathematically demanding than setting a table--is itself far from innate.
After children have helped to set the table with impressive accuracy, they ________.
A．are able to help parents serve dishes
B．tend to do more complicated housework
C．are able to figure out the total pieces
D．can enter a second-grade mathematics class
