13、ls in Medical Experiments,Task 05,A People have different opinions on using animals for research. B. 1. The case for using animals in research: a. Every drug anyone takes today was tried first on animals. b. Future medical research is dependent on the use of animal. c. Medical research is also a goo
14、d way of using unwanted animals.,Task 05,2. The case agaist using animals in research: a. Animals suffer a lot during the experiments. b. Much of the research is unnecessary. c. Animals have the same rights as humans do. 3. Some alternative ways for scientists to do their research: a. Using cell cul
15、ture. b. Using computer modeling.,Task 05 Script,Every year aobut seventeen million animals are used in Laboratory experiments. But in many countries today, a difficult question is being asked: do we have the right to use animals this way“ People who are for using animals in research argue that the
16、use of animals in medical research has many practical benefits. Animal research has enabled researchers to develop treatments ofr many diseases, such as heart disease and depression. It would not have been possible to develop vaccines for diseases like smallpox and polio without animal research. Eve
17、ry drug anyone takes today was tried first on animals. Future medical research is dependent on the use of animals. Which is more important: the life of a rat or that of a three-year-old child? Medical research is also an excellent way of using unwanted animals. Last year, over twelve million animals
18、 had to be killed in animal shelters because nobody wanted them as pets.,Task 05 Script,However those who are against it point out that the fact that humans benefit cannot be used to justify using animals in research any more than it can be used to justify experimenting on other humans. Animals suff
19、er a lot during these experiments. They are forced to live in small cages, and they may be unable to move. Much of the reaearch that is carried out unnecessary anyway. Animals have the same rights as humans do - to be able to move freely and not to have pain or fear forced on them. Researchers must
20、find other ways of doing their research, using cell culture and computer medeling. There should be no animals in research laboriatories at all.,Tiger Cub,Task 06,A. 1. No. 2. Because zoo officals want him to produce cubs with another female tiger, so they dont want him to become too interested in th
21、is family. B. 1. The young tigers are four months old. 2. Each of them weighs about 13 kilograms. 3. They eat horse meat and drink their mothers milk. 4. People with comupters can see the daily life of these teigers by visiting the National Zoos Website at www.si.edu/natzoo. C. 1.C, 2.C, 3.B,Task 06
22、 Script,Visitors to the National Zoo in Washington D. C. can see three new young tigers. The rare babies met the public for the first time late last month. Chip ONeal tells us about them. The mother tiger sat nearby on the grass as her babies rolled, chased and bit each other playfully. Then Korench
23、y also jumped into the games. Her cubs were born at the zoo four months ago. They are called Mike, Eric and Chrisy. The new young tigers at the National Zoo each weigh about 13 kilograms. Their fur is dark orange with black stripes. They eat horse meat and drink milk from Korenchy. Korenchy and her
24、babies are Sumatran tigers. Sumatran tigers came from the Indonesian island of Sumatran. They are now in danger of disappearing from the earth. Fewer than 500 of these tigers remain in the world. That includes about 60 living in zoos in North America.,Task 06 Script,Korenchy came to the National Zoo
25、 from the Jakarta Zoo in Indonesia. The girl was part of the Sumatran Tiger Species Survival Program. Korenchy has given birth to live cubs three tines. The father of her new cubs is Rokan, a Sumatran tiger who arrived two years ago from another zoo. Korenchy and Rokan had their babies the natural w
26、ay instead of the scientific method often used to produce young animals in zoos. A wire fence separates Rokan from his babies. Zoo workers who care for Rokan say he reaches through the fence to wash the cubs with his tongue. They say this means he recognizes Mike, Eric and Chrisy as his cubs. Howeve
27、r, zoo officials are hoping that Rokan will produce more cubs with another female Sumatran tiger at the zoo, so they do not want him to become too interested in this family. The National Zoo hopes to keep the Sumatran tiger cubs for at least 18 months before sending them to Other zoos. That is about
28、 the age when most tiger cubs in the wild leave their mothers. The National Zoo has placed cameras in the Sumatran tigers living area, so people with computers can see them. To do this, use your computer to find the National Zoos Website at www. si.edu/natzoo.,Cats and Dogs,Task 07,A. 1. Cats have b
29、een more popular, because there are more pet cats in American homes. 2. About 8,000 years 3. They probably arrived in the United States from Europe. 4. No. B. 1. The care of cats has become a big business, because cat owners: a. buy tons of food especially prepared for cats. b. buy toys and other eq
30、uipment. c. buy things with images of cats on them. d. bury their dead pets in special burial grounds.,Task 07,B. 2. People who prefer cats say cats: a. give their owners pleasure. b. need less care. c. suffer less from being alone. d. are more independent. C. 1.F, 2.F, 3.T, 4.F, 5.F,Task 07 Script,
31、An old expression says, “Mans best friend is his dog.“ Today, however, it seems that cats have replaced dogs as the most popular pets in American homes. Americans have more than sixty-two million pet dogs. But even more cats - more than sixty-four million - live in American homes. These pet cats may
32、 have long hair or short hair. They are different colors and sizes. Some are costly animals that take part in competitions. Many more are common American mixtures of several kinds of cats. Most house cats live a good life. They are not expected to work for their food. Instead, they rule their homes
33、like furry kings and queens. They wait for their owners to serve them. Americans are increasingly serious about their cats. These concerns have made the care of cats into big business. Each year, cat-owners buy tons of food especially prepared for cats. They buy toys and other equipment. They buy je
34、welry and clothes for themselves with images of cats on them. Some owners even bury their dead pets in special burial grounds.,Task 07 Script,Humans have loved and respected cats for centuries. Scientists have evidence that cats and people lived together as long as eight-thousand years ago. The smal
35、l house cat was once a highly honored animal. In ancient Egypt, for example, people who killed a cat could be punished by death. Early in American history cats were not treated as gods, however. They probably arrived in the United States with settlers and traders from Europe. These cats worked. They
36、 killed rats and mice. Sometimes, Americans mistreated their cats. During the early days of the nation, religious extremists believed that some cats were working for the devil. Black cats were especially suspected of being evil. Later, American families who had enough food began taking cats into the
37、ir homes. People cared for the cats because the animals gave them pleasure. The cats thanked people for feeding them by making a purring sound. This pleasant noise usually means a cat is happy.,Task 07 Script,Animal experts offer several reasons why cats have become so popular as house pets. They sa
38、y cats need less care than dogs. And cats do not seem to suffer as much as dogs from being alone if the owners are away. Still, millions of other people do not like cats at all. They say dogs are better and more loving pets. They say cats do not have much feeling. They believe cats stay with people
39、only to be fed. Cat owners defend their pets against such criticism. They say cats are just much more independent than dogs. A student of animal medicine explains the situation this way: Dogs follow you around. They want you to talk to them and play with them a lot of the time. Cats like more space
40、and more privacy. This does not mean they do not love their owners.,Task 08,Task 08,Little Steve has a pet rabbit, Bunny. He plays with it every day after school. One day his mother sees that her little boy is holding Bunny by the ears. From time to time he gives the poor rabbit an angry shake and s
41、ays: “How much is two plus two?” “Steve,” says his mother, “Why do you treat your poor little Bunny that way?” “Well,“ explains Steve angrily, “Our teacher says that rabbits multiply very quickly, but this dummy cant even add.“,Whales and Dolphins,Whales and Dolphins,Task 09 Script,Most mammals live
42、 on land, but not all of them. Millions of years ago, some mammals went back to the sea and lived there. The legs of these animals disappeared, and after a long time they looked like fish. These animals became whales and dolphins. Whales and dolphins are still like other mammals in many ways. They are warm-blooded and they breathe air. They also have big brains. That is why they are more intelligent than fish. Whales have the biggest brains in the world. Their brain is bigger than the brain of a human being.,
