A typical large supermarket offers around 20,000 items for sale and it wants to make sure that its customers see as many of them as possible. That's why you'll normally find the essential goods like bread, vegetables and meat in completely different parts of the store. Products with a high profit margin are always placed on shelves within easy reach of the customer, while lower margin items like sugar or flower are on the top or bottom shelves. Many people make shopping list before they visit supermarkets. But even so, around 60% of all supermarket purchases are the result of decisions that are taken in the store. For this reason, supermarkets try to attract their customers by placing certain kinds of product next to each other. In the UK, beer will often be found next to items for babies because research shows that fathers of babies buy them on their way home from work and will buy beer at the same time. Research has also shown that this kind of impulse buy happens more frequently when no sales assistants are nearby. Supermarkets have made selling such a fine art that their customers often lose all sense of time. When interviewed, customers normally guess they've only spent half an hour in the supermarket even when they have been there for over 45 minutes. But that shouldn't be too surprising. Any really profitable supermarket knows that it should keep its clocks well hidden.12. Where are goods with a high profit margin usually found?A. On the bottom shelves.B. On clearly marked shelves.C. On easily accessible shelves.D. On the top shelves.

The water level of oceans rises and falls alternately twice a day. This movement of water is called the tide. Tides are causer by the pull of the sun and the moon on the earth' s surface; since the moon is closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise because the water is pulled away from the earth. As the moon disappears over the horizon, the pull lessens and the water level settles back towards the ocean bottom. When the water reaches its highest level, we have high tide. And when the water comes to its lowest level, we have low tide from its lowest point, the water rises gradually for about six hours until it reaches high tide. Then it begins to fall continuously for about six hours until it reaches low tide. Then the cycle begins again.63. Which of the following may be the best title for the passage? A. The Moon and Ocean B. The Moon and the Tide C. Water Levels D. The Pull of the Moon and the Sun 64. The pull of the moon on the earth' s surface is stronger than that of the sun because ________ .A.

Starvation is the most fearful and the most dreaded of all the anxieties that haunt (萦绕) the minds and the imaginations of mankind. Mankind’s every effort has been directed to combat it and will continue to do so until the end of time. Its prevention has been the greatest motivation that ever kept men braced up in the struggle. It is the real enemy. Yet like every other enemy its presence brings forth the best that is in us and urges us to do greater things in the struggle. In the continuous fight against hunger and cold, man has progressed wonderfully and done more than what was absolutely necessary to merely guard against starvation. His future progress can only be made through keeping up the fight.The fight is the same now as it was when our early ancestor struggled with some living things and with their flesh satisfying his inward desire and with their skin keeping out the cold so that he might live, and for the time being to keep the anxiety at bay. The forces we have to fight now are different, but the struggle is the same. As he succeeded in conquering his victim to make his existence secure, so must we conquer the forces that are opposed to us or we will perish. Unlike our early ancestor, whose task is simple in the struggle for existence, we have to fight not only the natural conditions, but artificial ones which society has created.In the struggle we have conquered as far as getting enough to eat and enough to wear is concerned, for we have produced both in abundance and far in excess of what our necessities require. Foodstuffs are gathered and harvested every year in quantities so great that their consumption would be impossible. Various clothing material is manufactured in such quantities that nakedness should have become impossible. We have achieved so much in providing food and clothing that it is strange that some are still hovering on the brink of starvation. Productivity is continuously increasing and the quality of production is continually improving. Yet with all this we are haunted by starvation. Its dread presence is ever felt.1. In the sentence “… that ever kept men braced up in the struggle” (Paragraph One), the underlined phrase means _____.A) securedB) cheered up C) depressedD) bound up2. From the first paragraph, we learn that _____.A) mankind has been on the brink of starvation all the timeB) mankind has progressed a lot in the struggle against starvation C) mankind won’t win the battle against starvationD) mankind keeps fighting only for more food to meet their needs3. We have more difficulties in the struggle against starvation, because _____.A) our conditions are more complicated than before B) we have to make more people’s existence secureC) the natural conditions are worsening all the timeD) we are confronted with different kinds of starvation4. What do we learn from the passage about the supply of food and clothing now?A) We have enough food, but some are still naked.B) We have insufficient food and enough clothing materials.C) We have already produced sufficient food and clothing materials. D) People should produce more food and clothes to satisfy themselves.5. We are still haunted by starvation probably because _____.A) quality of what we produce is inferiorB) population growth is too fastC) the productivity is continuously getting lower.D) there may be some other problems with mankind.
