Wilma Subra had no intention of becoming a public speaker. After graduating from college with degrees in chemistry and microbiology, she went to work at Gulf South Research Institute in Louisiana.
As part of her job, she conducted field research on toxic (poisonous) substances in the environment, often in minority communities located near large industrial polluters. She found many families were being exposed to high, sometimes deadly levels of chemicals and other toxic substances. But she was not allowed to make her information public.
Frustrated by these restrictions, Subra left her job in 1981, created her own company and has devoted the past two decades to helping people fight back against giant industrial polluters. She works with families and community groups to conduct environmental tests, interpret test results, and organize for change.
Because of her efforts, dozens of toxic sites across the country have been cleaned up. And one chemical industry spokesperson calls her “a_top_gun” for the environmental movement.
How has Subra achieved all this? Partly through her scientific training.Partly through her commitment to environmental justice. But just as important is her ability to communicate with people through public speaking. “Public speaking，” she says, “is the primary vehicle I use for reaching people.”
If you had asked Subra before 1981 “Do you see yourself as a major public speaker？”， she would have laughed at the idea. Yet today she gives more than one hundred presentations a year. Along the way, she’s lectured at Harvard, testified before Congress, and addressed audiences in 40 states, as well as in Mexico, Canada, and Japan.What did Wilma Subra study for her job before 1981?
| A．Chemistry and microbiology. |
| B．Families affected by toxic chemicals. |

Authorities in Shanghai said Thursday night that another person has died from H7N9 bird flu, bringing the death toll to five around the country. The city has reported six infections (感染) to date, and four have died, said the Shanghai Municipal Health and Family Planning Commission. Of the rest two, there was a four-year-old, the agency said. The baby was recovering from mild illness, it added. The person died at Huashan Hospital on Wednesday and was confirmed infected with the H7N9 bird flu on Thursday.
Also on Thursday, the commission reported the city's third death from the H7N9 bird flu. The case involved a 48-year-old man surnamed Chu, a poultry (家禽) transporter from Rugao in neighboring Jiangsu Province. He developed symptoms(症状) of cough on March 28. After having a fever on Monday, he went to a private clinic for treatment. The man then sought help in the Tongji Hospital in Shanghai in the early hours of Wednesday after his condition worsened. Chu died three hours after being admitted to the hospital. He was confirmed infected with the H7N9 virus on Thursday. Eight people who had close contact with him have shown no abnormal symptoms.
So far, China has confirmed 14 H7N9 cases -- six in Shanghai, four in Jiangsu, three in Zhejiang and one in Anhui, in the first known human infections of the lesser-known type of bird flu. Of all, four died in Shanghai and one died in Zhejiang. China's Ministry of Agriculture said Thursday the H7N9 avian flu virus has been detected from pigeon (鸽子) samples collected at a marketplace in Songjiang District of Shanghai.
After gene sequence analysis, the national avian flu reference laboratory concluded that the H7N9 virus found on pigeons was highly congenetic with those found on persons infected with H7N9 virus. China's health authorities have promised transparency(透明) and cooperation (合作) to the World Health Organization in regards to human infections of the new type of bird flu. The Chinese Center for Disease Control and Prevention said Wednesday that no human-to-human transmission of H7N9 has been discovered.What does the underlined word “confirmed” probably mean?

Silence is unnatural to man．He begins life with a cry and ends it in stillness．In between he does all he can to make a noise in the world, and he fears silence more than anything else．Even his conversation is an attempt to prevent a fearful silence．If he is introduced to another person, and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of envy of the emptiest headed chatterbox（喋喋不休的人）.He knows that ninety-nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure（蜡塑人像）.
The aim of conversation is not, for the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito （蚊子）.But at a dinner party one would rather be a mosquito than a quiet person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would be a foolish man if he waited until he had a wise thought to take part in the buzzing -with his neighbors.
Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are content if they are merely allowed to go on making a noise into other people's ears, though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be successful conservationists.According to the passage, people usually talk to their neighbors_____.

Most people want to know how things are made. They honestly admit, however, that they hardly know a thing when it comes to understanding how a piece of music is made. Where a composer begins, how he manages to keep going – in fact, how and when he learns his trade – all are covered in complete darkness. The composer, in short, is a man of mystery .
One of the first things the common man wants to know about is the part inspiration plays in a composer’s work. He finds it difficult to believe that composers are not much interested in that question. Writing music is as natural for the composer as eating or sleeping for all. Music is something that the composer happens to have been born for.
The composer, therefore, does not say to himself: “Do I feel inspired?” He says to himself: “Do I feel like working today?” And if he feels like working, he does. It is more or less like saying to himself: “Do I feel sleepy?” If you feel sleepy, you go to sleep. If you don’t feel sleepy, you stay up. If the composer doesn’t feel like working, he doesn’t work. It’s as simple as that.What would be the best title for the text?
| A．Composer: a man of mystery |
| B．Practice makes good music |
| C．Relation between sleeping and music |
| D．Music: product of nature |
Most people seem to think that a composer ____.
| A．finds it difficult to write music |
| B．considers it important to have a good rest |
| C．should like to talk about inspiration |

| B．are people full of mystery |
| C．work late at night for their music |

The African elephant, the largest land animal remaining on earth, is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.What does the underlined phrase “setting the terms” most probably mean?
| A．Improving the quality. |

Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill(废渣填埋场),the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.What would be the best title for the text?
| A．Measures of Reducing Dangerous Waste |
| B．Danger of Harmful Waste to Mankind |
| C．Dangerous Waste and Water Pollution |
| D．Environmental Protection |
According to the text, people ________ .
| A．do not produce harmful waste in their daily life |
| B．do not know where to place the dangerous waste |
| C．are not clear about how serious the dangerouswaste problem is |
| D．are not sure about where harmful waste ends |
What troubles industries most in dealing with the dangerous waste problem?
| A．How to get government support. |
| B．How to increase their production. |
| C．How to store harmful waste. |
| D．How to cut down the related costs. |
What can be inferred from the passage?
| A．The polluting industries are not allowed to sell their products. |
| B．Present technologies have settled the harmful waste problem. |
| C．Everyone should obey the government rules for the problem. |
| D．To solve the problem requires the efforts of the whole society. |
