【文章內(nèi)容簡介】 anies 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 bee 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 society39。s ine differently， it raises some poor people above the poverty line. The government collects taxes from the non173。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. 24. The author39。s main purpose to write this article is ________. A． to define what the poverty line is B． to explain why some people live the poverty line C． to find solutions to the problem of poverty D． to show sympathy for those poor people 答案與解析： C 意圖推測題，主題句位于第一段 (Economists study the causes of poverty in order to find solutions to the problem.)。文章首先提出主題，然后圍繞它作了闡述，介紹了美國貧窮人口的一些基本情況：貧困人口的特點，原因等，最后重點講述了政府目前打算解決貧困問題的一些想法，最后又再次強調(diào)經(jīng)濟學(xué)家正在努力尋求更好的解決方案。所以 C項正確。其他各項均不能概括全文。 25． Which of the following is NOT true? A． Ten percent of the Americans live a poor life. B． Poor people are those who live below the poverty line. C． The poverty line rises as the general standard of living rises. D． The poverty line tends to be at the same level. 答案與解析： D 細節(jié)題。由第二段第一句 As the general standard of living in the country rises， the poverty does， too，可知隨著一個國家人民生活水平提高，貧困線的標準也正提高。 26． More than 40 percent of the poor people are children. This is mainly because ________. A． they do not have enough motivation B． they are so young that they don39。t have the right to work C． they fail to get enough education D． they are very poor in health 答案與解析： B 細節(jié)題。由文章第三段中的 By law， children less than 16 years old can39。t work in many ，是因為美國法律沒有給他們工作的權(quán)利。 27． We may concluded from the passage that ________. A． better solutions to the poverty problem are not yet found B． welfare will enable them to be rich C． poor people are sure to go out of the poverty line if they have chances to do business D． employment is the best solution to the poverty problem 答案與解析： A 推斷題。由文章最后一段可知：經(jīng)濟學(xué)家正在尋找更好的解決貧困問題的方案，但目前 (還沒找到 )，絕大部分貧困人口不得不依靠社會福利和低保維持生計。 C Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season. Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter， can also be bad for the health. Choosing the right food, therefore, has bee an area of study in modern life. 28． We can infer from the text that humans and animals ________. A． depend on one sense in choosing food B． are not satisfied with their food C． choose food in similar ways D． eat entirely different food 答案與解析： C 推理判斷題。根據(jù)第一段可知，人用氣味和味道來選擇食物，動物用一種或多種感覺選擇食物，從這點上人和動物是類似的。 29． Which of the following eats only one type of food? A． The white butterfly. B． The small bird. C． The bear. D． The fox. 答案與解析： A 細節(jié)理解題。根據(jù)第二段 “A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden” 可以推斷出這種白蝴蝶只吃卷心菜。 30． Certain animals change their choice of food when ________. A． the season changes B． the food color changes C． they move to different places D． they are attracted by different smells 答案與解析： A 細節(jié)理解題。根據(jù)第二段 “The diet of these animals will be different depending on the season” 可以推斷出這些動物的食物隨著季節(jié)而變化。 31． We can learn from the last paragraph that ________. A． food is chosen for a good reason B． French and British food is good C． some people have few choices of food D． some people care little about healthy diet 答案與解析： D 推理判斷題。根據(jù)最后一段 “We often eat food because we like it and not because it is good for us” 可知我們選擇食物經(jīng)常是因為喜歡而不是對身體有
