Read the passage carefully, then choose the correct answer
The first system of communication of animals is natural. Many kinds of animals have ways of communicating with each other. And one of the most interesting examples is that of bees. These insects communicate with each other by dancing. The most important kind of dance that they do is concerned with food. They get their food from flowers, of course, from plants and trees. When a bee has found some food, it returns to the other bees and can give them three basic kinds of information about the food: which direction it is in, whether it is nearby or a long way away, and whether it is good to eat or poisonous.
The other kind of system of communication of animals is artificial. It means animals learn it; in this case, they learn from man. Several famous experiments have been carried out with chimpanzees, trying to teach them human language.
One of these experiments was done with a chimpanzee called Sarah. Sarah was taught to understand a system of symbols which represented words. The symbols were cut out of coloured plastic, and each different shape stood for a different word. For example, a red square stood for “banana”, Sarah’s favorite fruit. Soon Sarah could not only understand words, but even sentences. She could obey orders: if her human friends put down the symbols for “apple in cup”, she would put the apple in the cup. Later, she began giving the scientists orders – she was writing her own sentences, and she got upset if the scientists did not obey her. We do not yet know whether chimpanzees will ever learn to use language to communicate as freely as human beings do, but the results so far suggest that this is at least a possibility.

Báo cáo của Liên Hiệp Quốc nhìn một hành tinh cô đơn hơn với ít cây cối, động vật hơn
Trái đất đang mất dần các thực vật, động vật và nước sạch với tốc độ đáng kể, theo bốn báo cáo khoa học mới của Liên Hiệp Quốc. đưa ra cách nhìn toàn diện và địa phương về tình trạng đa dạng sinh học. Các cuộc họp của các nhà khoa học ở Colombia đã đưa ra 4 báo cáo về tình trạng động vật và thực vật ở châu Mỹ; Châu Âu và Trung Á; Châu phi; và khu vực Châu Á Thái Bình Dương. Kết luận của họ sau ba năm nghiên cứu: Không nơi nào làm tốt.
Chủ tịch nhóm nghiên cứu, ông Robert Watson, cho biết nền tảng chính sách khoa học-chính phủ về đa dạng sinh học và hệ sinh thái không chỉ là những con vật. Đó là việc giữ cho trái đất có thể sống được cho con người, bởi vì chúng ta dựa vào đa dạng sinh học đối với thực phẩm, nước sạch và sức khoẻ cộng đồng, nhà khoa học Anh và Mỹ nổi tiếng nói. "Điều này đang làm suy yếu sự thịnh vượng của chúng ta, đe dọa chúng ta lâu dài về thức ăn và nước," Watson nói trong một cuộc phỏng vấn. Các nhà khoa học đã chỉ ra cái chết cuối cùng của con tê giác trắng cuối cùng ở châu Phi và sự sụt giảm nghiêm trọng về số lượng con voi, hổ và tê tê, nhưng nói rằng đây chỉ là loài có khả năng nhìn thấy và hấp dẫn nhất đối với các loài đang gặp rắc rối.
Điều gì đang xảy ra là một ảnh hưởng phụ của thế giới ngày càng giàu có và đông đúc hơn với người dân, Watson nói. Con người cần nhiều thức ăn, nước sạch hơn, năng lượng và nhiều đất hơn. Và cách mà xã hội đã cố gắng đạt được đã làm giảm sự đa dạng sinh học, ông nói. Môi trường sống chủ yếu đã bị cắt đứt; các loài ngoại lai xâm lăng; hóa chất đã gây hại cho thực vật và động vật; vùng đất ngập nước và rừng ngập mặn làm sạch ô nhiễm đang biến mất; và vùng biển của thế giới bị đánh bắt quá mức, ông nói. Theo Watson, biến đổi khí hậu do con người gây ra ngày càng tồi tệ hơn và sự ấm lên toàn cầu sẽ sớm ảnh hưởng đến đa dạng sinh học cũng như tất cả các vấn đề khác
Wild animals (and wild plants) and the wild places where they live are seriously threatened almost everywhere. One species has become extinct in each year of this century. But many hundreds are now in danger. Lack of attention would lead to the rapid advance of the process of extinction.
Already many kinds of wild animals have been so reduced in number that their role in the ecosystem is forgotten. Animals like the great apes, the whales, seals etc. thought to be in danger of extinction.
But even more important, perhaps than individual kinds of animals and plants, whole habitats are in danger of vanishing: marshes are being drained, and the world forests, especially tropical forests are being cut down to satisfy man’s needs of timber and paper.

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
VI. Read the text then answer true or false
People use many sources of energy. Ancient people used only their arms, hands, and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy. Energy is one of the basic concepts, or ideas, of physics. It is the ability to do work. Without energy we could live. We need energy to work, and scientists are always looking for new sources of energy.
1. None of the world’s energy comes from the sun. F
2. Wind, steam, and gasoline are sources of energy. T
3. People have never used nuclear energy. F
4. Energy is the ability to do work. T
5. We need new sources of energy. T
