听力原文： Advertisement can be thought of as "the means of making known in order to buy or sell goods or services". Advertisement aims to increase people's awareness and arouse interest. It tries to inform. and to persuade. The media are all used to spread the message, such as, the press, the cinema and commercial radio, television and so on. Other ways of increasing consumer interest are through exhibitions and trade fairs as well as direct mail advertisement.
There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement.
We might ask who pay for the cost of advertisement, the producer or the customer？ Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for advertisement.
It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to increase demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. What is clear is that business would not pay large sums for advertisement if they were not convinced of its value to them.

听力原文： There was once a man who spent all his time in his glasshouse. Flowers was his name, and flowers were his main joy in life. He grew flowers of every color under the sun. He grew these flowers in order to enter them for competition. His greatest hope in life was to grow a rose of an entirely new color that would win him the silver cup for the Rose of the Year.
Mr. Flowers' glasshouse was close to a public path, which was always used by children walking to and from school. Boys were often attracted to throw a stone or two at his glasshouse. So Mr. Flowers did his best to be in or close by his glasshouse at the beginning and end of the school day.
However, it was not convenient or possible to be on guard all the time. Mr. Flowers had tried in many ways to prevent harm to his glasshouse, but nothing that he had done had been successful.
Then, just as he was giving up hope of ever winning the battle, and of growing the Rose of the Year, he had a truly wonderful idea. He put up a large notice made of good, strong wood, some meters away from the glasshouse, where it could be clearly seen from the path. He had painted on the board the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble. The boys were much more attracted to throw stones at the notice than at the glasshouse.

A．To grow beautiful flowers.
B．To grow a rose of new color and win a prize.
C．To grow all kinds of flowers in the world.
D．To take part in the competition.
听力原文： Shop-lifters can be divided into three main categories: the professionals, the deliberate amateurs, and the people who just can't help themselves. The professionals do not pose much of a problem for the store detectives assisted by closed circuit television, two-way mirrors and various other technological devices. The professionals tend to go for high value goods in parts of the shops where security measures are the tightest. And, in any case, they account for only a small percentage of the total losses due to shoplifting.
The same applies to the deliberate amateurs who are, so to speak, professionals in training. Most of them get caught sooner or later, and they are dealt with severely by the courts.
The real problem is the person who gives way to a sudden temptation and is in all other respects an honest and law-abiding citizen. Contrary to what one would expect, this kind of shop-lifter is rarely poor. He does not steal because he needs the goods and cannot afford to pay for them. He steals because he simply cannot stop himself. And there are countless others who, because of age, sickness or plain absentmindedness, simply forget to pay for what they take from the shops. When caught, all are liable to prosecution, and the decision whether to send for the police or not is in the hands of the store manager.
In order to prevent the incredible growth in shop-lifting, some stores are doing their best to separate the thieves from the confused by prohibiting customers from taking bags into the store. However, what is most worrying about the problem is that it is yet another instance of the innocent majority being penalized and inconvenienced because of the actions of a small minority.

A．The professionals who go for high value goods cause great loss to the stores.
B．The deliberate amateurs do not pose much a problem for the stores.
C．Those who can't help themselves account for only a small percentage.
D．All of the shop-lifters will be dealt with severely by the courts.
Have you ever wondered how a nuclear power plant works or how safe nuclear power is？ In this article, we will examine how a nuclear reactor and a power plant work.
Uranium
Uranium is a fairly common element on Earth, which was taken into the planet during the planet's formation. Uranium is originally formed in stars. Old stars exploded, and the dust from these shattered stars aggregated together to form. our planet. Uranium-238 (U-238) has an extremely long life (4.5 billion years), and therefore is still present in fairly large quantities. U-238 makes up 99 percent of the uranium on the planet. U-235 makes up about 0.7 percent of the remaining uranium found naturally, while U-234 is even rarer and is formed by the decay of U-238.
Nuclear Fission (裂变)
A nuclear fission happens when a uranium-235 nucleus with a neutron captures another neutron. The nucleus then splits into two lighter atoms and throws off two or three new neutrons (the number of ejected neutrons depends on how the U-235 atom happens to split). The two new atoms then produce gamma radiation as they settle into their new states. There are three things about this induced fission process that make it especially interesting:
The probability of a U-235 atom capturing a neutron as it passes by is fairly high. In a reactor working properly (known as the critical state) , one neutron ejected from each fission causes another fission to occur.
The process of capturing the neutron and splitting happens very quickly, on the order of picoseconds (1×1012seconds).
An incredible amount of energy is released, in the form. of heat and gamma radiation, when a single atom splits. The two atoms that result from the fission later release beta radiation and gamma radiation of their own as well. The energy released by a single fission comes from the fact that the fission products and the neutrons, together, weigh less than the original U-235 atom. The difference in weight is converted directly to energy at a rate governed by the equation E = mc2.
In order for these properties of U-235 to work, a sample of uranium must be enriched so that it contains 2 percent to 3 percent or more of uranium-235. Three-percent enrichment is sufficient for use in a civilian nuclear reactor used for power generation. Weapons-grade uranium is composed of 90-percent or more U-235.
Inside a Nuclear Power Plant
To build a nuclear reactor, what you need is some mildly enriched uranium. Typically, the uranium is formed into pellets (芯块) with approximately the same diameter as a coin and a length of an inch or so. The pellets are arranged into long rods, and the rods are collected together into bundles. The bundles are then typically submerged in water inside a pressure vessel. The water is used to lower the heat. In order for the reactor to work, the bundle, submerged in water, must be slightly supercritical. That means that, left to its own devices, the uranium would eventually overheat and melt.

Through the establishment of military posts, yet other contributions were made to the development of western culture. Many posts maintained libraries or reading rooms, and some had schools. Post chapels provided a setting for religious services and weddings. Throughout the wilderness, post hands provided entertainment and boosted morale. During the last part of the nineteenth century, to reduce expenses, gardening was encouraged at the forts, thus making experimental agriculture another activity of the military. The military stationed at the various forts also played a role in civilian life by assisting in maintaining order, and civilian officials often called on the army for protection.
Certainly, among other significant contributions the army made to the improvement of the conditions of life was the investigation of the relationships among health, climate, and architecture. From the earliest colonial times throughout the nineteenth century, disease ranked as the foremost problem in defense. It slowed construction of forts and inhibited their military function. Official documents from many regions contained innumerable reports of sickness that virtually incapacitated entire army. In response to the problems, detailed observations of architecture and climate and their relationships to the frequency of the occurrence of various diseases were recorded at various posts across the nation by military surgeons.
Which of the following statements best expresses the main idea of the passage？
A．By the nineteenth century, forts were no longer used by the military.
B．Surgeons at forts could not prevent outbreaks of disease.
C．Forts were important to the development of the American West.
D．Life in nineteenthcentury forts was very rough.
