Passage ThreeQuestions 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.

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.

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.

共用题干New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.“Some”in“some still exist today”(Para. 1)means______.A:some cocoa treesB: some chocolate drinksC: some shopsD: some South American Indians

It may be pointed out that warfare（战争）as practiced by man has no parallel in nature,This is to say that within the more highly developed animal populations of this earth,there is not now.nor has there been similar destruction within a species（物种）itself.In fact,one has to go to the lowliest forms of animal life,such as certain kinds of ants,to find anything comparable to human warfare.It is a curious fact that mankind appears to give the killing of his own kind a good reason by imaging that it is a"law of nature".There are now a lot of wrong ideas about the laws of nature,of which this is one of the most incorrect and fateful（致命的）.Political beliefs have been based upon it with results that have come near to destroying human civilization.The theory that war is a biological necessity.that it is nature′s method of controlling population and believing in the survival（生存）of the strong and the elimination（灭亡）of the weak,is totally wrong and insupportable.Within the last century.when wars have been common all over the world,the human population of the earth has almost doubled.According to Sentence 2,which of the following is true?A.The destruction is similar to the killing of each other within human beings.B.There is not the similar destruction now,but it occurred before.,'C.There is never a time when we may see the similar destruction.D.The destruction is now a thing of the past.
