| The United States has a major racial
problem on its hands. True, Britain is facing a similar problem, but for the
time being it is in America that it is graver. The only way to solve it is
through education. Negroes should know about the contributions that black
individuals and groups have made towards building America. This is of vital
importance for their self-respect, and it is perhaps even more important for
white people to know. For if you believe that a man has no history worth
mentioning, it is easy to assume that he has no value as a man. Many people believe that, since the Negro’s achievements do not appear in the history books, he did not have any. Most people are taken aback when they learn that Negroes sailed with Columbus, marched with the Spanish conquerors of South America and fought sid A.

The Tough Grass That Sweetens Our Lives
Sugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose（蔗糖）and was chewed on for its sweet taste. Over time,sugar cane became a highly valuable commercial plant,grown throughout the world. _________(46) Sugar became a vital ingredient in all kinds of things ,from confectionery（糖果点心）to medicine , and, as the demand for sugar grew ,the industry became larger and more profitable.__________(47)Many crops withered（枯萎）and died,despite growers' attempts to save them ,and there were fears that the health of the plant would continue to deteriorate. In the 1960s ,scientists working in Barbados looked for ways to make the commercial species stronger and more able to resist disease. They experimented with breeding programmes,mixing genes from the wild species of sugar cane,which tends to be tougher, with genes from the more delicate,commercial type. ___________(48)This sugar cane is not yet ready to be sold commercially,but when this happens,it is expected to he incredibly profitable for the industry. ____________ (49)Brazil , which produces one quarter of the world's sugar, has coordinated an intema- tional project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo. Teams of experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health. Despite all the research ,however, we still do not fully understand how the genes function in sugar cane. ___________(50)This gene is particularly exciting because it makes the plant resistant to rust,a disease which probably originated in India,but is now capable of infecting sugar cane across the world.Scientists believe they will eventually be able to grow a plant which cannot be destroyed by rust. ________（46） A.Since the 1960s,scientists have been analysing the mysteries of the sugar cane'S genetic code. B.Unfortunately,however,the plant started to become weaker and more prone to disease. C.The majority of the world'5 sugar now comes firm this particular commercial species. D.One major gene has been identified by Dr Angelique D'Hont and her team in Montpeller,France. E.Eventually,a commercial plant was developed which was 5 percent sweeter than before,but also much stronger and less likely to die from disease. F.Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed. [填空题]蒸发器分为（）和（）两大类，其中冷却液体的蒸发器有（）和（）两种。
