Passage Two Not content with its doubtful claim to produce cheap food for our own population, the factory farming industry also argues that "hungry nations are benefiting from advances made by the poultry industry". In fact, rather than helping the fight against malnutrition(营养不良) in "hungry nations", the spread of factory farming has, inevitably aggravated the problem. Large-scale intensive meat and poultry production is a waste of food resources. This is because more protein has to be fed to animals in the form of vegetable matter than can ever be recovered in the form of meat. Much of the food value is lost in the animal’s process of digestion and cell replacement. Neither, in the case of chicken, can one eat feathers, blood, feet or head. In all, only about 44% of the live animal fits to be eaten as meat. This means one has to feed approximately 9-10 times as much food value to the animal than one can consume from the carcass. As a system for feeding the hungry, the effects can prove disastrous. At times of crisis, grain is the food of life. Nevertheless, the huge increase in poultry production is seen throughout Asia and Africa continues. Normally British or US firms are involved. For instance, an American based multinational company has this year announced its involvement in projects in several African countries. Britain’s largest chicken supplier, Ross Breeders, is also involved in projects all over the world. Because such trade is good for exports, Western governments encourage it. In 1979, a firm in Bangladesh called Phoenix Poultry received a grant to set up a unit of 6,000 chickens and 18,000 laying hens. This almost doubled the number of poultry kept in the country all at once. But Bangladesh lacks capital, energy and food and has a large number of unemployed. Such chicken-raising demands capital for building and machinery, extensive use of energy resources for automation, and involves feeding chickens with potential famine-relief protein food. At present, one of Bangladesh’s main imports is food grains, because the country is unable to grow enough food to feed its population. On what then can they possibly feed the chicken The last paragraph is the author’s ______
A. detailed analysis of the ways of raising poultry in Bangladesh
B. great appreciation of the development of poultry industry in Bangladesh
C. critical view on the development of the poultry industry in Bangladesh
D. practical suggestion for the improvement of the poultry industry in Bangladesh

Passage Three "Hi there. How’s it going" "Oh, fine. Fine. How about this weather, huh" "Well, I guess we can always use the rain." What’s that This story Oh, just a little look at small talk. You know, those seemingly meaningless conversations you have dozens of times a day, Maybe you’re waiting for the elevator. Or in a line at the bank. It all seems pretty trivial. Idle chatter about traffic doesn’t do much more than fill the air with empty words that are quickly forgotten. But you should know that small talk actually has a big place in our lives. Pat Oliver, assistant professor on arts, says that, "Left unchecked, small talk can be an invasion. It’s so powerful. It does something to you." "Every morning after spending an hour and a half on the freeway I start the day with small talk with my secretary," Oliver says, "IfI don’t make small connection with another person, I can’t work." What causes it As a rule, you’re either trying to force something into your life, or you’re using conversation as an invisible force field to keep them out. You can be wanting to connect with another person, and small talk is your introduction to more meaningful conversation. The way people use small talk is usually determined by where they happen to be at the time. Take the elevator, for instance. Now there’s prime territoo,. Nobody knows anyone and there’s no reason to start a conversation, but invariably, someone does. Making conversation in such peaceful social settings, according to Oliver, "can confirm your territory. It’s a way of feeling liked and accepted." The topics of small talk don’t matter. In fact, you don’t want anything more taxing than the weather or the traffic. It’s non-threatening talk in a threatening situation. However, the rules change quickly when you’re with lots of people doing lots of talking. Let’s say you’re at a party. Now it’s time to use small talk as a way of making others feel more comfortable around you, so you don’t look silly standing by the food table alone all night. According to the author, small talk is often used______
A. to protect one’s own privacy
B. to invade other’s private affairs
C. to share a secret between intimate friends
D. to open and maintain channels of communication
Passage Four One of America’s greatest exports to the rest of the world has been entertainment. America, a nation of incredible energy and talent, has flooded the world markets with her films, theaters and songs. In America the two centers where this talent is most brilliantly and successfully essayed are Hollywood and Broadway. Hollywood is a district within the city of Los Angeles. Its name is synonymous with the motion-picture industry. Since the early 1900s, when movie makers found southern California an ideal blend of mild climate and varied geography, it has become the home for cinematic dreams. All the great names of cinema have passed through Hollywood on the road to international careers. Today it still remains the place where dreams are said to come true and fantasies are carefully nurtured. Known as "The Movie Capital of the World", Hollywood is one of the few places where epic films can still be made on such a large scale. Ancient Rome, the Pharaoh’s Egypt or a science fiction film staged somewhere in the Galaxy are all within the imagination of the filmmakers and the industry they control. It is a place where unknowns are discovered and even actors from abroad have come to Hollywood to further establish their fame and recognition. With the coming of television Hollywood began to alter its function. By the early 1960s it had become the source of the majority of U.S. network television entertainment. But, its place as the center of the movie industry in America has remained undiminished and unchallenged. On the east coast of America, however, in New York it is live theater which provides the source of culture and entertainment. Here it is the dramatic stage which dominates the cultural scene. The main avenue which runs through the city is known as Broadway. ①It traverses the length of Manhattan and near the middle clustered the many theaters that have long made it the foremost showcase of commercial stage entertainment in the United States. The term Broadway was at one time virtually synonymous with American theater activity. In the 1980s the street became known as "The Great White Way" because of its brilliant display of lights in the evening. ② As the power and prosperity of New York City grew in the world, so did the number, size and magnificence of the Broadway theaters. Broadway soared into its peak in the mid 1920s. At this time there were over eighty theaters on Broadway but in recent years the number has declined. Yet, it still remain vibrantly active and under constant renewal. American people made Hollywood the center of the movie industry for its______
A. location
B. mild climate and varied geography
C. talented citizens
D. wealth
