  Did you ever imagine having a child that is the exact replica(復制品) of you? Did you ever imagine of having the cure for heart disease or cancer? Well, these fantasies are not far from reach. The way we could reach these fantasies is through a process called cloning. Cloning is the replication of an exact genetic copy of an organism by use of a somatic tissue (or cell) from the donor organism. Cloning can be used in humans, human organs, or even animals. There are many advantages and disadvantages of cloning.

  A benefit of cloning is cloning human organs or body parts. If a person has a dysfunctional(變形) liver or heart then they could get it cloned and get a brand new one. These are some of the benefits of cloning. Even though there are a lot of benefits to cloning, there are also a lot of disadvantages of cloning. One disadvantage is whether cloning is ethical. Cloning will bring up a great controversy on whether cloning is the “right” thing to do or not. This controversy is currently going on right now and will be even a greater controversy if the government allows cloning. Many people think that nature should just take its course. Other people think that cloning will be a very good thing to society. 句型背誦
