Passage 1

Bananas are one of the world’ s most important food crops. They are also one of the most valuable exports. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses. For example, the Cavendish banana is most popular in North American and European markets. However，some kinds of fungus organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plant’s leaves. Farmers put anti-fungal chemicals on their crops up to once a week.

Another fungal disease is more serious. Panama disease attacks the roots of the banana plant. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America.

The International Network for the Improvement of Banana and Plantain supports research on bananas. The group has headquarters in France and other offices in the major banana-growing areas of the world. The group says that more research must be done to develop improved kinds of bananas. The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five hundred different kinds of bananas. Food and Agriculture Organization of the United Nations has said that the Cavendish banana represents only 10% of world production.

The U.N. agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This happened earlier to another popular banana because of its genetic weakness against disease.

Passage 2

“Can I see my baby？” the happy new mother asked. When the bundle was in her arms and she moved the fold of cloth to look upon his tiny face, she gasped. The doctor turned quickly and looked out of the tall hospital window. The baby had been born without ears.

Time proved that the baby’ s hearing was perfect. It was only his appearance that was imperfect. When he rushed home from school one day and threw himself into his mother’s arms, she sighed, knowing that his life was to be misfortunate. He cried out the tragedy, “A boy, a big boy... called me a freak (怪人)．”

He grew up, handsome. A favourite with his fellow students, he might have been class president, but for that. He developed a gift, a talent for literature and music. “But you might communicate with other young people，” his mother blamed him, but felt a kindness in her heart.

Two years went by. One day, his father said to the son, “You’ re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’ s a secret.” The operation was a brilliant success, and a new person emerged.

Later he married and entered the diplomatic service. One day, he asked his father, “Who gave me the ears? Who gave me so much? I could never do enough for him or her.” “I do not believe you could，” said the father, “but the agreement was that you are not to know... not yet.”

The years kept their secret, but the day did come. He stood with his father over his mother’ s casket. Slowly, tenderly, the father stretched forth a hand and raised the thick, reddish brown hair to reveal the mother had no outer ears.

“Mother said she was glad she never let her hair be cut，” his father whispered gently, “and nobody ever thought Mother less beautiful, did they？”

66．Why did Mother gasp when she saw her newborn baby? A. Because her son had a tiny face. B. Because she saw her son crying. C. Because her son was born imperfect. D. Because her son was in her arms.

67．Which word can describe Mother’ s feeling when the son threw himself into her arms? A. Nervous. B. Sympathetic. C. Proud. D. Angry. 68．Who gave the son the ears? A. …… 此处隐藏：5540字，全部文档内容请下载后查看。喜欢就下载吧 ……
