Questions 36 to 45 are based on the following passage. It was 10 years ago, on a warm July night, that a newborn lamb with took her first breath in a small shed in Scotland. From the outside, she looked no different from thousands of other sheep born on __36__ farms. But Dolly, as the world soon came to realize, was no __37__ lamb. She was cloned from a single cell of an adult female sheep, __38__ long-held scientific dogma that had declared such a thing biologically impossible. A decade later, scientists are starting to come to grips with just how different Dolly was. Dozens of animals have been cloned since that first little lamb — mice, cats, cows and, most recently, a dog — and it’s becoming __39__ clear that they are all, in one way or another, defective. It’s __40__ to think of clones as perfect carbon copies of the original. It turns out, though, that there are various degrees of genetic __41__. That may come as a shock to people who have paid thousands of dollars to clone a pel cat only to discover that the baby cat looks and behaves __42__ like their beloved pet — with a different-color coat of fur, perhaps, or a __43__ different attitude toward its human hosts. And these are just the obvious differences. Not only are clones __44__ from the original template (模板) by time, but they are also the product of an unnatural molecular mechanism that turns out not to be very good at making __45__ copies. In fact, the process can embed small flaws in the genes of clones that scientists arc only now discovering. 36（）
