Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Recently, the news has been filled with reports of the "bird flu." Asia is on a region-wide health alert, with governments slaughtering millions of chickens to contain outbreaks of the bird flu in Thailand, Vietnam, Cambodia, South Korea, Japan and China.
Influenza—commonly called "flu"—is one of the oldest and most common diseases known to man. It can also be one of the deadliest. The great "Spanish flu" pandemic(传染病) of 1918-1919 was considered the worst plague in history, killing up to 40 million people with half of the world's population infected in only a few months.
Influenza can also infect many different warm-blooded animals, such as birds. However, the "flu" virus usually develops different variants that are specialized for each species of animal that they infect. Cross species infections are rare.
A flu strain called influenza A(H5N1) appears to have made a successful jump from birds to humans. The viral strain(病毒株) was first isolated from, South African birds in 1961. The first known human infection occurred in a Hong Kong child in May of 1997. By the end of 1997, there were 13 confirmed cases and four deaths, all in Hong Kong. In an attempt to stop the spread of the disease, Hong Kong authorities ordered the slaughter of all chickens, ducks, geese, and domestic pigeons.
Human infected with H5N1 so far are thought to have caught the disease from fowl and no person-to-person transmissions have been reported. The World Health Organization, however, feats that the bird flu is highly adaptable and might leap the species barrier. It says anyone exposed to the disease should be isolated to avoid contact with sufferers of regular human influenza.
The recent outbreak of bird flu results in______.

听力原文： Have you ever noticed advertisements which say "Learn a foreign language in 6 weeks, or your money back! From the first day your pronunciation will be excellent. Just send..." and so on？ Of course, it never happens quite like that. The only language that is easy to learn is the mother tongue. And think bow much practice that gets! Before the Second World War people usually learnt a foreign language in order to read for literature of the country. Now speaking the foreign language is what most people want. Every year many millions of people start learning one. How do they do it？
Some people try at home with books and records or tapes; some use radio or television programs; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like language learning at school. A few people try to learn a language fast by studying for 6 or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary, they need the language in order to do their work better. For example, scientists and doctors chiefly need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the student's work for him.

听力原文： The climate of the west coast is the most moderate in Canada. Summers are coast and fairly dry and winters are mild, cloudy and wet. Even in mid-winter, average temperatures are usually above freezing.
The central plain from the Rocky Mountains to Great Lakes is characterized by cold winters, short but hat summers, and light snow and rain.The large water-surfaces of Central and Eastern Canada produce considerable modification in the climate. Southern Ontario and Quebec experience cold, damp winters and hot, humid summers.
Most of Atlantic Canada has a humid climate owing to its marine character. Nevertheless, it experiences weather systems arriving from the dry continental interior as well as from the sea. The combined influence of these systems creates some of the most variable day-to-day weather conditions to be encountered anywhere in Canada.
The north-central part of Canada is usually snow-covered for more than half of the year, with a frost flee period of barely two months. Rain is relatively light. Further north, on the islands along the Arctic coast and round Hudson Bay, the land is always frozen. Average temperatures stay above freezing for only a few weeks of the year. The Arctic Islands and the northern border of the mainland do not have a summer season of the kind known in Southern Canada.
