(2). Use your own words to show the writer’s viewpoints.
Example:
A:Which champion athlete can run 100 metres in 8 seconds?
B:I don’t know. But we come across the issue-enhancing drugs. These drugs are developed to help people with illnesses, but in the wrong hands, they create “supreme athletes”.
A: Taking these drugs is known as “doping”,they cause problems for those who abuse them.
B:The sports world does not tolerate doping as it is a fundamental form of cheating.
A: Yes. “Gene-therapy ”will be the next big threat. It is controversial and many people oppose further research into it.
B: I agree. Both doping and gene-therapy violate the Olympic spirit. The spirit of competition-higher,faster, stronger-emphasises taking part rather than winning.That’s why thousands of people are crazy about their hero and the great Olympic!
