Botswana lies immediately to the north of South Africa. It is bordered on the north and west by Namibia, on the north and east by Zimbabwe, and is connected by a narrow strip of land on the northern border to Zambia. Its territory consists almost entirely of a broad, flat, arid subtropical plateau(高原), though there are hills in the eastern part of the country.
In the northwest, the Okavango River empties into the Kalahari sands, creating the largest inland river delta in the world. While the Okavango Delta is home to relatively few large animals in comparison to other areas of Botswana, its clear waters and countless small islands are home to a variety of birds, plants, and smaller species of animals.
Nearby is Chobe National Park, a beautiful grassland reserve(保护区) that has gained international fame for its large elephant population. Southeast of Chobe are Botswana's large Makgadikgadi salt pans, home to numbers of blue wildebeest, several antelope species, and those international lovers of salt pans, flamingos(a kind of birds).
Almost the entire remaining portion of the country is covered by the Kalahari Desert--a varied environment of sand and grassland. Although this area of Botswana is where few people live, it is one of the richest wildlife areas in all of Africa.
Botswana's two largest parks, the Central Kalahari Game reserve and Gemsbok National Park, are found in this region.
Botswana's climate can get rather cool, particularly during the dry winter months of June to August when night occasionally brings frost. The rainy summer months (December through March) are best avoided for those interested in enjoying the best game viewing conditions.

DOES the Yangtze River still have baiji（白鳍豚）, the graceful, grey dolphin with tiny eyes and a long narrow beak? Since November 6, a team of scientists from China, Switzerland, the United Kingdom, the United States, Germany and Japan have been searching for any sign of the freshwater dolphin on the middle and lower sections of the river. After six weeks, they came back empty-handed.

Wang Ding, of the Chinese Academy of Sciences, who is the head of the team, said he has seen a sharp decline in the baiji population over the past few decades. However, he is still unwilling to call the species extinct, and adds, “We will try every effort to save them as long as they are not found to be extinct.”

The baiji is shy and nearly blind and is one of the world’s oldest dolphin species. It dates back some 20 million years and is found only in the Yangtze. It's listed as one of the 12 most endangered animal species in the world.

Around 400 baiji were believed to be living in the Yangtze until the 1980s. 1 A 1997 survey spotted 13. Two years later their numbers were down to two.

The rapid disappearance of this dolphin over the past two decades coincided with the rapid expansion of economic development along the river. Research on some dead baiji collected in recent years showed that more than 90 per cent of the deaths were caused by human activities.

One reason is that over-fishing has cut the dolphin's food sources. Dams built along the river and neighbouring waterways have also kept them from swimming into and out of their habitats (居住地). Meanwhile, waste discharge (排放) has seriously polluted the river. And heavy river traffic has greatly reduced their living space.

The disappearance of the baiji would be the first instance of a large aquatic (水生的) mammal being driven to extinction since hunting killed off the monk seal around 1952.

1．Which of the following statements is true?

       A．The baiji is already extinct.

       B．Man is mainly responsible for the sharp decline in the number of baiji.

       C．There are about 12 baijis now in China.

       D．Human activities make the baiji almost blind.

2．What does the underlined sentence mean?

       A．People don’t find out the fact that the baiji is already extinct.

       B．We shouldn’t give up saving the baiji despite its limited number.

       C．Our effort is worthless if we can’t protect the baiji.

       D．Effort will lead to more population growth of the baiji.

3．Monk seal is talked about in the last paragraph in order to show        .

       A．baijis might be faced with the same threat as monk seals

       B．the monk seal is one of the large aquatic mammals

       C．mammals are more likely to be killed off

       D．the number of monk seals was very small

4．According to the passage, all the measures to help save baiji are mentioned except        .

       A．reducing the number of the ships traveling in the river

       B．building fewer dams along the river

       C．limiting and controlling the amount of fishing

       D．conducting more scientific research on the baiji
