Detail reading Step1 Choose the best answers. 1. The film Jurassic Park is popular because _____.

A. people are interested in the subject of cloning

B. all the actors are dinosaurs

C. it was directed by a scientist who clones dinosaurs

D. it proves very interesting 2. Which of the following is true? ____ A.Mice were cloned in 1981. B. Dolly the sheep was the first cloned animal. C. The name of the cloned cow is “Bison”

D. China was successful in cloning mammals. 3. From the first paragraph, how many kinds of animals have been cloned since 1950s?

Seven: frogs, mice, cows, sheep, calves, cats, dog. Step2 Give some reasons why it is either impossible or unsuitable to clone extinct animals. Reason 1:

You need perfect DNA Reason 2:There is not enough diversity for cloned animals to overcome new diseases. Reason 3:It would be unfair to clone any extinct animals if they would have to live in a zoo. Step3 Diversity in a group of cloned animals Advantage of diversity If there is a new illness, some of these animals

may die, but others will survive and passed on the ability to resist that disease to their children Disadvantage of diversity They would all have the same arrangement of genes and so they might all die of the same disease.

Conclusion: The chance of dinosaurs returning to the earth is

_merely a dream_____________.

语言知识点

1. The popularity of films such as Jurassic Park, in which a scientist clones several kinds of extinct dinosaurs, proves how the idea struck a mixture of fear and excitement into people’s hearts.
