Every year farmers in areas which often suffer flood in Southeast Asia lose millions of tons of rice to high water that kills their crops. That large amount of waste may soon be a thing of the past: SUBIA, a gene discovered by researchers which the International Rice Research Insitule (IRRI) and the University of California, allows rice palnts carrying the gene to live completely under water for two weeks.
Flood – resistant(抗水浸) rice turned up among the 110,000 types of seed stored at the institute. It produced disappointingly low yields(产量) , but scientistis were able to transfer the gene into more bountiful varieties. These have shown promising results in tests by growers in India and Bangladesh over the past two years.
This rice success story would not have been possible without the treasure of genetic diversity hidden in the IRRI’s vault (underground room). As the world faces new agricultural challenge – charging climate, bugs and diseases that have developed resistance(抵抗力) to old defenses – such genetic resources are likely to become increasingly valuable. Fortunately, the IRRI is one of more than 1,000 organizations around the world working to protect crop genes. Most plant species grown for food have an associated bank that stores thousands of samples; seeds of landraces, wild relatives, and varieties that are rare, old, or adapted to very specific envionments. The banks ensure that it will be possible to develop new varieties in the future.
The need for these botanical libraries has its roots in modern agricultural practices. According to the U. N. Food and Agriculture Organization, 75 percent of plant diversity has been lost over the last century. Of more than 30,000 eatable species, humans grow just 200 for food; 60 percent of plant calories in our diet comes from wheat, rice, and corn.
72.Accordint to the second paragraph, what can we learn about the flood – resistant rice?
A.It produces a small amount of rice.
B.Scientists have developed many more varieties of it.
C.Sientists have managed to improve its output.
D.It can produce more rice than the other 110,000 types at the institute.
73.From the passage we can infer that .
A.the newly – discovered gene will bring hope to the farmers in the areas often suffering flood
B.scientists will not be able to change the fact that rice plants carrying the gene produce low yields
C.the tests by growers in India and Bangladesh were hopeless
D.110,000 types of seed stored at the Institute are flood - resistant
74.What’s the main idea of the third paragraph?
A.The world faces new agricultural challenges.
B.Such genetic resources are likely to become valuable.
C.Scientists set up banks to store thousands of seed samples.
D.We should owe the rice success story to the seed banks.
75.As to the botanical libraries, the writer thinks they are .
A.useless B.unnecessary C.needful D.needless

解析
Zhao Wenxuan,a film star from Taiwan,has been fond of seeing films since his childhood. He would sometimes go to the cinema for the same film four or five times. He also enjoys literature and art. Before he took the film acting as his career,he had worked in an airline in Taipei, the capital of Taiwan Province. His change of job to acting was quite by chance.
One day,he came across in the paper an advertisement for a leading actor to appear in the film named “Wedding Feast.” Full of excitement,he answered the job ad by telephoning the director of the film — Mr. Li An. It was this telephone call that had changed all his life. At last the director decided him to be the very person for the role. That he could be chosen owed much to his good command of English,natural manners and low pay for his work in the film.
The film “Wedding Feast” proved to be a hit. It won the German Golden Bear Award and entered the competition for one of the Oscar Academy Awards. Also, it was the first Taiwan film that was permitted to be shown in the U. S. Thanks to the film,Zhao Wenxuan became popular in Taiwan, Hong Kong and southeast Asia.
In 1994,Mr. Zhao acted as a leading role in the Hong Kong film,“Red Rose and White Rose”,in which many film stars like Ms Chen Chong from U. S. and Ms Ye Yuqing from the local area participated. This film was named for 10 prizes of the Taiwan Golden Horse Prize and at last it was awarded five prizes for the best play,actress and music. Zhao has regarded the film as one of his favorite films since he stepped into the acting circle.
Since 1993,Mr. Zhao has taken part in the shootings of 13 films, most of which are thought highly of.
Mr. Zhao said the that Taiwan should think to cooperate much with the mainland in the film producing industry and it would benefit each other. In recent years he often came to the mainland for film shooting. He has just completed his performance in the film “Love Affairs” directed by Mr. LiXin,a director from Shanghai Film Studio.
