In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus (病毒) kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops.
Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri.
The lab mainly works on genes (基因), the chemical “computer programs” found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering.
Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes.
That’s just the beginning, Wambugu believes. Genetically modified (转基因的) foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.
小题1:The text is written mainly to _______.
| A．tell us sweet potatoes are in danger of being attacked by a virus |
| B．introduce Wambugu’s contribution to genetic engineering |
| C．introduce a new way of killing plant viruses |

William Porter rented this house in Austin and lived there with his wife Athol and daughter Margaret for about two years. Many objects in the museum belonged to the Porters. Others did not. An important piece in the room is the original photograph over here. It was taken there in the house about 1895. The piano there goes back to the 1860s. His wife took lessons on it when she first moved to Austin.
Porter did not start his career as a successful writer. He worked at a farm, land office and bank. He also loved words and writing. The museum has a special proof of Porter’s love of language --- his dictionary. It is said that he had read every word in that dictionary.
Later William Porter was forced to leave Austin because he was charged with financial wrongdoing at the bank and lost his job. Because he was afraid of a trail (审判), he left the country secretly. But he returned because his wife was dying. After her death, he faced the trial and became a criminal. He served three and a half years in a prison in Ohio.
William Porter would keep his time in prison a secret. But there was one good thing about it. It provided him with time to write. By the time he was freed, he had published 14 stories and became well known as O.Henry.
Porter later moved to New York City and found great success there. He published over 180 stories in the last eight years of his life.

A. Americans can explore their history
B more visitors will be attracted to Austin
C. visitors can learn about O.Henry’s life

小题2:What do we know about the piano in the house?
| A．It was hated by Porter’s daughter. |
| B．It has a long history of about 150 years. |
| C．Porter’s wife gave music lessons on it. |
| D．Porter usually created music on it. |
| A．With a dictionary he used. | B．With the records they keep. |
| C．Using the books they wrote. | D．Using the photograph they keep. |
| A．He didn’t want to lose his job. | B．He didn’t want to make trouble. |
| C．He meant to save his wife’s life. | D．He was charged with a crime. |

When James was a teenager, his father 36 him to a fur factory where he worked . This was during the Great Depression. The 37 was to get James a job.
James entered the factory, and immediately felt as if the 38 had closed in around him. The room was dark and hot, the windows covered with dust, and the 39 were packed tightly together, running like trains. The fur hairs were flying, 40 a thickened air, and the workers, 41 the pieces of fur together, were bent over their needles 42 the boss marched up and down the rows, searching for them to go faster .James could hardly 43 . He stood next to his father, frozen with fear, hoping the boss wouldn’t 44 at him, too.
During lunch break, his father took James to the boss and pushed him in front of him, 45 if there was any work for his son. But 46 there was hardly enough 47 for the adult labours, for no one would give it up once he took a job.
Thus, for James, it was a 48 . He hated the place. He made a 49 that he kept to the end of his life: he would never do any work that brought 50 to someone else, and he would never allow himself to 51 money off the seat of others.
“What will you do?” his mother, Eva, would ask him.
“I don’t know,” he 52 say. He ruled out law, because he didn’t like 53 , and he ruled out medicine, because he couldn’t take the 54 of blood.
“What will you do?”
55 , my best professor I ever had became—he thought it was the job not to hurt anybody.
