Opinions are divided.Some believe that human cloning is a good thing. Firstly, They think if people had too much work to do , they could get their own clone to help them. That wouldn’t be cheating because it would still be themselves doing the work. As a result, they would have so much time to rest and have fun. What’s more, human cloning could alsosolve the problem of finding the organs for organ transplants. Sothat it could help people lead longer and healthier lives.However, others are against it .They think human cloning is a terrible idea, which could cause a lot of problems. First of all, it could cause family confusion. If people were cloned , how could their clone fit into their family? Remember, their clone would be exactly like them. In addition, clone could cause problem for society. If everyone decided to be cloned there would be a population of explosion.In my opinion, I ’d prefer to have human cloning . In that case, we can clone people with special talents that would be helpful for social development.People are against the human cloning and the argument Paragraph 1Writer’s opinion about thetopic Paragraph 2People are for the human cloning and theargument Paragraph 3Introduction of thetopic Paragraph 4Task 2：Read the passage to fill in the formTask 3：find out topic sentences in each paragraph.Paragraph 1 Topic sentence________________________________________________________________1)______________________________________________________________2) _____________________________________________________________3)______________________________________________________________Opinions _____ whether we choose to be treated by Chinese traditional Medicine _____________________.（人们关于是否选择使用中药治疗的看法不同）。
