Tapescript Listening Test Yourself D English 12

High in dense bamboo forests in the misty mountains of southwestern China lives one of the world's rarest mammals: the panda. Pandas feed mainly on bamboo shoots and leaves. Occasionally they eat other plants, fish or small animals. Pandas eat fast and they eat a lot. They spend 12 hours a day doing it.

Pandas are extremely endangered today. There are only about 600 of these black-and-white bears in the wild and a hundred in captivity. One of the reasons is that the survival rate of the cubs is very low: more than half of them die shortly after birth. Chinese government is considering cloning the panda in their efforts to save this animal.

Ở những ngọn núi sương mù phía tây nam Trung Quốc trong những rừng tre cao dày đặc là nơi sinh sống của một trong những động vật có vú hiếm nhất thế giới: gấu trúc. Gấu trúc ăn chủ yếu đọt măng và lá. Đôi khi chúng ăn các loại thực vật khác, cá hoặc động vật nhỏ. Gấu trúc ăn nhanh và rất nhiều. Chúng dành 12 tiếng một ngày để làm việc đó.

Ngày nay gấu trúc đang bị đe dọa nguy. Chỉ có khoảng 600 con gấu đen trắng trong tự nhiên và một trăm con bị giam nhốt.

Chính phủ Trung Quốc đang xem xét nhân bản gấu trúc trong việc nỗ lực cứu loài vật này.

Rất khó biết ngày xưa có bao nhiêu con voi sống ở lục địa này, nhưng có lẽ có ít nhất 3-5 triệu con ở Phi châu vào đầu thế kỉ 20. Người ta luôn săn voi để lấy thịt, da và ngà. Khi dân số tăng và vũ khí trở nên tiến bộ hơn, loài voi phải đứng trước mối đe dọa lớn hơn. Vào cuối thập niên 70 và đầu thập niên 80 số lượng voi đã giảm khủng khiếp vì việc săn trộm tăng. Người ta ước tính rằng hiện nay có khoảng 500.000 con voi và chúng đang sống ở một số ít quốc gia. Lệnh cấm mua bán ngà voi trên khắp thế giới đã được ban hành năm 1989. Nhờ những hành động kịp thời, một số quần thể voi, đặc biệt những đàn voi ở Nam Phi, đã phục hồi suốt thập kỉ vừa qua. Tuy nhiên, vô số mối đe dọa vẫn còn với voi Phi châu.

Guide to answer Writing Test Yourself D English 12

Rhinos are one of  the endangered animals that are on the verge of extinction. Rhinos are large animals and need a lot of space to live in. Now people can find them in grasslands, tropical and sub-tropical forests in Africa and southern Asia. A rhino is about from 1,2 to 1,8 meters high and weighs from 1,000 to 3,000 kg. Their main food is grass and plants. A rhino's average lifespan is about 40 years.

It is estimated that there are now about 17.000 rhinos in the world. But there is a great decline in the population of rhinos due to the hunting and poaching, and especially their habitat destruction.

World Wildlife Fund has been working to conserve rhinos for over 40 years. It has launched rhino conservation projects to protect this species from extinction by translocating rhinos to the conservancy run by local communities.

• Câu 1:

  Exercise 1: Read the passage carefully and choose the correct answer.

  Plants and animals hold medicinal, agricultural, ecological value. Endangered species must be protected and saved so that future generations can experience their presence and value.

  Plants and animals are responsible for a variety of useful medications. In fact, about forty percent of all prescriptions written today are composed from the natural compounds of different species. These species not only save lives, but they contribute to a prospering pharmaceutical industry worth over $40 billion annually. Unfortunately, only 5% of known plant species have been screened for their medicinal values, although we continue to lose up to 100 species daily. The Pacific yew, a slow-growing tree found in the ancient forests of the Pacific Northwest, was historically considered a "trash" tree. However, a substance in its bark was recently identified as one of the most promising treatments for ovarian and breast cancer. Additionally, more than 3 million American heart disease sufferers would die within 72 hours of a heart attack without digitalis, a drug derived from the purple foxglove.

  There are an estimated 80,000 edible plants in the world. Humans depend upon only 20 species of these plants, such as wheat and corn, to provide 90% of the world's food. Wild relatives of these common crops contain essential disease-resistant material. They also provide humans with the means to develop new crops that can grow in inadequate lands such as in poor soils or drought-stricken areas to help solve the world hunger problem. In the 1970s, genetic material from a wild corn species in Mexico was used to stop a leaf fungus that had previously wiped out 15% of the U.S. corn crop.

  Plant and animal species are the foundation of healthy ecosystems. Humans depend on ecosystems such as coastal estuaries, prairie grasslands, and ancient forests to purify their air, clean their water, and supply them with food. When species become endangered, it is an indicator that the health of these vital ecosystems is beginning to unravel. The U.S. Fish and Wildlife Service estimates that losing one plant species can trigger the loss of up to 30 other insect, plant and higher animal species. The northern spotted owl, listed as threatened in 1990, is an indicator of the declining health of the ancient forests of the Pacific Northwest. These forests are the home to over 100 other old-growth dependent species, which are at risk due to decades of unsustainable forest management practices. Pollution off the coast of Florida is killing the coral reefs along the Florida Keys, which serve as habitat for hundreds of species of fish. Commercial fish species have begun to decline, causing a threat to the multi-million dollar tourism industry, which depends on the quality of the environment.
