Animal experimentation is the backbone (支柱，基础) of American research and treatment of disease. Each year, 17 million to 22 million animals are sacrificed in the name of science. While 90 percent of them are rats and mice, 180,000 dogs, 50,000 cats, 61,000 monkeys and 554,000 rabbits are done away with in laboratories operated by industry and government.
But the public has raised an outcry (抗议) over these deaths. Spurred vivid reports of cruelty, the animal rights movement is made up of 7,000 organizations with 10 million members. They've documented cases in which monkeys were isolated in steel tanks for 45 days and dogs were bombarded (轰击、辐射) with radiation or chemicals until they bled from the mouth.
Scientists say such incidents are rare. Laws have been passed to govern testing. Many research centers now have committees to review all proposed animal experiments, and computers can be used in place of animals in many experiments. But scientists say they can't do without animals to test new drugs and treatments on animals to make sure they're safe for humans. Animal experiments produced vaccines (疫苗) or treatments for diseases such as diabetes (糖尿病), and techniques used in open heart surgery. They're important to efforts to find a treatment for AIDS.
Animal rights activists have shown they will go to almost any length (奉陪到底). One New York researcher received more than 10,000 protest letters following publicity of her experiments in which she gave drugs to monkeys. The researcher was studying drug addiction. A protester was arrested in Connecticut for placing a pipe bomb outside a company that used animals in tests. After fires and break-ins, many labs have bought electronic locks and alarms for protection. Other targets of the animal rights movement are the fur industry, farms, and school biology classes in which children dissect (解剖) frogs.
The movement has scored some successes. A dozen states no longer allow pounds (兽栏) ── places that accept dogs and cats that have no homes ── to sell animals to scientists. Scientists claim the cost of their work will rise as a result.
The battle between scientists and activists raises a basic question: Can modern society be both humane (仁慈的) in its treatment of living things and advanced in its treatment of disease? It seems certain there will be new restrictions placed on the use of animals in scientific experiments.
1.The main idea of the article is ________.
A.fewer animals should be taken to laboratories
B.Americans are questioning the use of animals in experiments
C.mice and rats make the best subjects for experiments
D.scientific experiments can be carried out without animals

The largest land animal remaining on the earth, the African elephant is of much importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a giant plant-eater, it significantly shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore deciding the conditions of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it both a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, as well as pulls branches off big trees. This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth, which attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants create open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large-hoofed plant-eaters to move around and for small-sized plant-eaters to obtain their food as well.
Scientists are worried now that the African elephant has become an endangered species. If the elephant dies out, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.
1.What is the passage mainly about?
A. Disappearance of African elephants.
B. Forests and savannas as habitats for African elephants.
C. The effect of African elephants' search for food.
D. The eating habit of African elephants.
2.The African elephant influences the ecosystem in the following ways except that .
A. it creates open areas in deep tropical forests as well as woodlands
B. it pulls off the branches and leaves, shutting out the sunshine
C. its eating habit can be made use of by large-hoofed and small-sized animals
D. it encourages some kinds of plants growing in an indirect way
3.According to the passage, which of the following statements is true?
A. Numerous grown plants are the favorites of plant-eaters.
B. The extinction of the African elephant has nothing to do with the ecosystem.
C. Quantities of plants are consumed by African elephants, including branches and underbushes.
D. The forest floor in rain forests is scarcely dotted with new shoots.
4.The passage is developed mainly by .
A. presenting the changes in time order
B. making comparisons and giving examples
C. classifying similarities and differences
D. showing the effect and then explaining the reasons

Natural selection is the process by which one type of animal within a species thrives because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth（灰蛾）is an example of the natural selection process.
In 19th century England, certain types of peppered moths were able to better blend（融合）into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this process occurred comparatively quickly.
At the beginning of the Industrial Age, most peppered moths in England were light-colored and covered with black markings, although a few moths had dark-colored wings. Because the light-colored moths blended into the light-colored bark on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks became covered with soot（烟煤）and became darker. The light-colored moths became easy for birds to see against the dark tree trunks. Since the dark-colored moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-colored to being mostly dark-colored.
In the 20th century, the air cleared up, and the peppered moth population changed again. As tree trunks lighted due to less soot in the air, light-colored moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the coloration of the moths helped them to be “naturally selected” to survive.
1.In 19th century, what was one of the causes of great changes in Great Britain?
A.The surroundings. B.The Industrial Revolution.
C.The natural selection. D.The peppered moth.
2.What can we infer about the peppered moth’s natural selection process?
A.The length of time was unusual.
B.The soot levels in England did not affect it.
C.The color of peppered moths changed at random.
D.It was a good example of environmental protection.
3.What’s the difference between light-colored and dark-colored moths?
A.Dark-colored moths were originally easy to see on trees.
B.Both kinds of moths preferred the dark-colored trees.
C.Birds failed to see light-colored moths.
D.The color of moths was unimportant.
4.Which would most likely happen if soot darkened England’s trees again?
A.Birds would eat fewer moths.
B.Moths would not be able to stay alive.
C.Light-colored moths would disturb people’s life.
D.The population of dark-colored moths would increase.
