Passage Three Questions 31 to 35 are based on the following passage. One of the most exciting races ever run is now in progress between doctors fighting malaria(疟疾)and mosquitoes. According to the most recent counts 225 million people a year suffer attacks of malaria and more than two million die. Public health workers around the world are doing all t11ev can to destroy malaria before the mosquitoes that pass on the disease become resistant to the poisons now used against them. It’s a race against time and against difficulties,with millions of lives in danger and the chances of winning not in man’s favour. Malaria,it is true,has been practically wiped out in thirteen countries. including the United States,and is under attack in many others. But it is equally true that in some parts of the world certain types of malaria-carrying mosquitoes have already learned to resist some of the sprays that formerly killed them. Other types of mosquitoes are not killed as quickly by present sprays as they once were. The World Health Organization is helping national governments to get rid of malaria before resistance among the mosquito population becomes so great that new poisons will have to be found to replace those in use at present. Most of the countries in the world have started,or are planning,campaigns against mosquitoes. If the race against resistance is won by man,it is possible that ten years from now dais old evil will have disappeared completely from the America,perhaps from the world. Which of the following statements is NOT mentioned in the passage
A. Malaria is under attack in a number of countries.
B. Some types of mosquitoes have become resistant to the current sprays.
C. New poisons have been put into wide use with the new science.
D. One of human’s challenges is to win the campaigns against mosquitoes.
Passage Two Questions 26 to 30 are based on the following passage. A few years ago it was fashionable to speak of a generation gap,a division between young people and their elders. Parents complained that children did not show them proper respect and obedience,while children complained that their parents did not understand them at all. What had gone wrongWhy had the generation gap suddenly appearedActually,the generation gap has been around for a long time. Many critics argue that it is built into the fabric of our society. One important cause of the generation gap is the opportunity that young people have to choose their own life styles. In more traditional societies,when children grow up,they are expected to live in the same area as their parents,to marry people that their parents know and approve of,and often to continue the family occupation. In our society,young people often travel great distances for their educations,move out of the family home at an early age,marry-or live with-people whom their parents have never met,and choose occupations different from those of their parents. In our upwardly mobile society,parents often expect their children to do better than they did:to find better jobs,to make more money,and to do all the things that they were unable to do. Often,however,the ambitions that parents have for their children are another cause of the division between them. Often,they discover that they have very little in common with each other. Finally,the speed at which changes take place in our society is another cause of the gap between the generations. In a traditional culture,elderly people are valued for their wisdom,but in our society the knowledge of a lifetime may become obsolete overnight. The young and the old seem to live in two very different worlds,separated by different skills and abilities. No doubt,the generation gap will continue to be a feature of American life for some time to come. Its causes are rooted in the freedoms and opportunities of our society,and in the rapid pace at which society changes. The word“around”in paragraph 1 means______.
A. on all sides
B. in every direction
C. near
D. in existence
