In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:The more the man ran, the greater loss of body fat.The more they ran, the greater their increase in food intake.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.1、What kind of physical problem do many adult Americans have?____A、They are too slim.B、They work too hard.C、They are too fat.D、 They lost too much body fat.2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____A、 30.B、 50.C、100.D、150.3、Is there scientific evidence to support that eating too much is the cause of a "weight problem"?____A、Yes, there is plenty of evidence.B、Of course, there is some evidence to show this is true.C、There is hardly any scientific evidence to support this.D、We don't know because the information is not given4、In comparison with the adult American population today, the Americans of ____.A、ate more food and had more physical activitiesB、ate less food but had more activitiesC、 ate less food and had less physical exerciseD、had more weight problems5、What have modern medical and scientific researches reported to us?____A、Fat people eat less food and are less active.B、 Fat people eat more food than slim people and are more active.C、 Fat people eat more food than slim people but are less active.D、 Thin people run less, but have greater increase in food intake.

Your Bean Steak (素肉排), Sir!What sort of food are we likely to be eating in the year 2000?Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed ( 分配 ).This does not mean, however, that our diet ( 饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.1.Most people believe that food supplies in the future().A、will become a very serious problemB、will be the same as they are todayC、will be enough in quantity but not good in qualityD、will be much better than they are today2.The reason why people are hungry in today's world is().A、poor farming methods and bad distributionB、slow growth of food productionC、food shortages all across the worldD、fast rising population3.The word "bacon" in Line 5, Para.3 most probably is().A、a kind of "meat" made from grainB、meat made from fishC、food for fishD、meat made from pigs4.The word "particular" in Line 4, Para.4 means().A、specialB、choosyC、detailedD、very exact5.The title of this passage suggests that().A、food in the future will be tastelessB、there will be worldwide food shortagesC、diet in the future will be very differentD、science is making rapid progress

More Rural Research is NeededAgricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer,crop scientist,said demand was growing at 2 .5%per year but with modern tech-nologies and the development of new ones,the world should be able to stay ahead.“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition（营养不良）and poverty.” he said.Research is needed to solve food production,land degradation（贫瘠化）and environmental problems. Secure local food supplies led to economic growth which in turn,slowed population growth .Dr. Fischer painted a picture of the world's ability to feed itself in the first 25 years, when the world's population is expected to rise from 5 .8 to 8 billion people.He said that things will probably hold or improve but there'll still be a lot of hungry people.The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in 2020,similar to the current pattern. if there is any change,a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia,South America and South-East Asia.The developing world was investing about 0 .5%,or$8 billion a year,of its agricultural gross domestic product(GDP)on research and developed world was spending 2 .5%of its GDP. Dr. Fischer said more was needed from all countries.He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs（有用的副产品）for Mexico, China or India.“Technologies still need to be refined for the local conditions but a lot of the strategic re- search can have global application,so that money can be used very efficiently.”Dr. Fischer said.Yields of rice, wheat ad maize（玉米）have grown impressively in the past 30 years, espe- cially in developing countries.For example,maize production rose from 2 to 8 tones per hectare between 1950 and 1995.But technologies driving this growth such as high-yield varieties,fertiliz-ers,and irrigation,were becoming exhausted.“If you want to save the land for non-agricultural activities,for forests and wildlife,you're going to have to increase yield.”Dr. Fischer said. What is the picture of Asia's food supplies in the first 25 years?A: Food shortage will not be a problem.B: There will be more hungry people in southern Asia.C: Population growth will result in more hungry people.D: There will be fewer hungry people in East Asia.

When Our Eyes Serve Our StomachOur senses aren't just delivering a strict view of what's going on in the world;they're af-fected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who'ye just eaten.Psychologists have known for decades that what's going on,inside our head affects our senses. For example,poorer children think coins are larger than they are,and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis,France,wanted to investi-gate how this happens. Does it happen right away as the brain receives signals from the eyes or a lit-tle later as the brain's high-level thinking processes get involved.Radel recruited 42 students with a normal body mass index. On the day of his or her test,each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes;others were given an hour to get lunch first. So half the students were hungry when they did the ex-periment and the other half had just eaten.For the experiment,the participant looked at a computer screen. One by one,80 words flashed on the screen for about 1/300th of a second each. They flashed at so small a size thatthe students could only consciously perceive. A quarter of the words were food-related. After each word,each person was asked how bright the word was and asked to choose which of two words they'd seen一a food-related word like cake or a neutral word like boat. Each word ap-peared too briefly for the participant to really read it.Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen,this means that the difference is in perception,not in thinking processes,Radel says.“This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment,I know that our brain can really be at the disposal of our mo-tives and needs,”Radel says.Radel's experiment discovered that hungry people______.A: were more sensitive to food-related words than stomach-full peopleB: were better at identifying neutral wordsC: were always thinking of food-related wordsD: saw every word more clearly than stomach-full people

资料： The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.
As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today’s relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs.
For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor. People are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are Old. Many companies do not hire people over 65 years old, the normal retirement age.
Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job.
Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer.
At the present time, the government thinks it can reduce poverty in the country in the following ways. First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer be below the poverty line. Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer. Then it is more likely that they can find jobs.
Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government collects taxes from the non－poor and gives money to the poor. These payments to the poor are called welfare. In 1975 over 18 million people in the United States received welfare.
Some economists are looking for better solutions to the poverty problem. However, at the present time, many people depend on welfare for a minimally acceptable standard of living.
We may conclude from the passage that _______A.poor people are bound to go out of the poverty line if they have chances to do business
B.welfare will enable people to be rich
C.employment is the best solution to the poverty problem
D.better solutions to the poverty problem are not found yet
