Please enjoy some pictures about dinosaurs.霸王龙tyrannosaurus 角龙ceratopsidsTask 3 Background reading for listeningShould humans be cloned?Physicians from the American Medical Association and scientists with theAmerican Association for the Advancement of Science have issued formal public statements advising against human reproductive cloning. Currently, the U.S. Congress is considering the passage of legislation that could ban human cloning.Due to the inefficiency of animal cloning(only about 1 or 2 viable offspring for every 100 experiments) and the lack of understanding about reproductive cloning, many scientists and physicians strongly believe that it would be unethical to attempt to clone humans. Not only do most attempts to clone mammals fail, about 30% of clones born alive are affected with “large offspring syndrome” and other debilitating conditions. Several cloned animals have died prematurely from infections and other complications. The same problems would be expected in human cloning. In addition, scientists do not know how cloning could impact mental development. While factors such as intellect and mood may not be as important for a cow or a mouse, they are crucial for the development of healthy humans. With so many unknowns concerning reproductive cloning, the attempt to clone humans at this time is considered potentially dangerous and ethically irresponsible.In class:Step1 Check-up and lead inStep 2 Fast readingRead the passage quickly and find out the main idea about the text.Step 3 Careful readingI.
