\(Read the following passage and choose the most appropriate answer from A,B,C or D to answer questions. Rain forests cover less than six percent of the earth’s area, but they have 100,000 kinds of all the kinds of plants on the earth. Three-fourths of known kinds of plants and animals call the rain forest their home. Twenty percent of our different kinds of medicine come from rain forests. The glues on an envelope and in shoes come from tropical plants. Rain forests provide materials for hundreds of other products. Rain forests are also very important to the world’s climate. The Amazon rain forest alone receives about thirty to forty percent of the total rainfall on the earth and products about the same percentage of the world oxygen. Some scientists believe that the decreasing size of rain forests will affect the climate on the earth, making it uncomfortable or even dangerous for life. Saving rain forests is an international problem. One country, or even a few countries, cannot solve the problem alone. The nations of the world must work together to find a solution before it is too late. 1. What percent of the earth’s area do rain forests cover? A. Only 6 percent B. 20 percent C. less than 6 percent D. over 6 percent 2. How many known kinds of plants and animals call the rain forests their home? A. B. C. D. 3. What percent of the total rainfall on the earth does the Amazon rain forests receive? A. about 20 to 30 B. less than 30 C. exactly 30 to 40 D. about 30 to 40 4. According to some scientists, what will the decreasing size of rain forests affect on the earth? A. oxygen B. climate C. plants D. only animals 5. According to the passage, what must the nations of the world do to find a solution? A. work together B. work alone C. save rain forests only D. save their lives \)

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.

What would our world be like if all the wild animals and wild plants vanished? - Would our life still exist then?

1. What would happen to the human beings if the wild life vanished?

A. Many species would quickly become extinct.

B. The human life would be seriously threatened.

C. Species would go on dying out.

D. Tropical forests would be cut down.

2. What is more important than individual kinds of animals and plants?

A. the vanishing of whole habitats. B. the extinction of many species.

D. man’s need of timber and paper. C. the rapid advance of the process of extinction.

3. What does the writer caution us against?

A. cutting down the tropical forests. B. hunting wild animals.

C. draining marshes. D. destroying our environment.

4. What would happen if we cut down forests?

Cutting down forests would cause ……………..

A. the changes of temperature. B. the flood

C. both A and B are correct. D. none are correct.

5. “To threaten” in the passage means …………..

A. to pollute B. to give fear to C. to vanish D. to poison

Enveloped by an ocean of air consisting of 78% nitrogen and 21% oxygen, the planet is the only one in our solar system known to harbor life. Circling the Sun at an average distance of 149 million kilometers (93 million miles), Earth is the third planet from the Sun and the fifth largest planet in the solar system.

 

   Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago. The Earth has a single natural satellite – the moon.

QuestionThe main idea of this passage is that ________.

A. Earth is predominantly water.

B. There are life-supporting characteristics on Eart

C. Earth is the only planet with a moon

D. Earth has no common characteristics with other planets
