Unit 2.Cloning

连词成篇

Be Careful about Cloning After a series of initial experiments and corrections, the scientist’s hard work paid off when the twin clone turkeys were hatched with normal feather and claws. This breakthrough possibly enabled people to bring their adorable pets back to life. However, it bothered him from time to time that their health was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely 2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired before he attained his ambition and became a member of an opera chorus to relieve his depression. Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial profits from cloning. When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge, any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may walk into a side road.”
