quickly and find the main idea of each part.Fast ReadingMatch the parts with the main ideas.
Part 1 A
Part 2 B
Part 3 CScientists have found the answer to one of the most important questions of biology. That is how living things reproduce themselves. List four examples to illustrate the application of the genes in our present and future lives. Scientists can use the technology of genetic engineering to insert new genes into human beings to create new characteristics. Read three parts separately.Detailed ReadingPart 1: Answer the questions
1. When and who astonished the scientific community?
2. What had Watson and Crick succeeded in?
On February 28,1953, two scientists named James Watson and Francis Crick astonished the scientific community.Watson and Crick had succeeded in understanding the structure of DNA and how genes are able to reproduce themselves.Part 2: T or F questions
1). People can find murders by comparing DNA.
2). People can have good-looking, very intelligent children by using a technology called genetic engineering.
3). An athlete is inserted an animal gene into his body, but he fails to run faster.

It is possible that we will create only one kind of people.

After the teacher says “begin”, the student who gets up earliest will get the chance to choose and answer the question.DABCEFWhich one do you choose?1. In story A, how did the police put Waters into prison?
2. ... our genes, which pass hereditary characteristics on to our children.
