They are all cloned(克隆) dogs, China Daily reported. The dogs were born in August. They were cloned from two police dogs that have helped police solve many murder cases(谋杀案).Early in 2019, scientists took some cells(细胞) from the dogs' skin and created cloned embryos(胚胎). Then, they put the embryos into three mother dogs. One mother gave birth to four dogs, while the other two gave birth to one each. The cloned dogs' DNA is a 99­percent match with their “fathers”．It is hoped that the cloned dogs will be as talented as their “fathers” because they are cloned. The cloned dogs are just four months old, but have already shown that they are brave and clever, as well as having good memories, according to Ma Jinlei, a police officer at the center. So it will take less time and money to train them.The world's first cloned dog was born in South Korea in 2005. However, animal cloning is still a hot talk. The world's first cloned animal, Dolly, the sheep, died at the age of 6 in 2003, about 6 years earlier than most sheep. Some people have questioned whether cloning technology is safe.What's more, some people worry that cloning technology may be used on humans someday and therefore may cause some ethical(道德的) problems.()49.When the six cloned dogs came to the police dog training center, they were ________.A．one month old B．three months oldC．half a year old D．six years old()50.People trained the six dogs to ________．A．help blind peopleB．help police solve casesC．develop cloning technologyD．do scientific experiments()51.Paragraph 3 mainly talks about________．A．how cloned dogs help police solve casesB．why cloned dogs are better than normal dogs C．the technology of cloning dogsD．the advantages of cloned dogs()52.The example of Dolly shows that ________．A．cloned animals live bad livesB．animal cloning is not newC．cloning technology is widely used on animals D．it is hard to say whether cloning is good or not ()53.What can we learn from the passage? A．Cloned animals can help people in some ways. B．Cloning technology is safe for the animals. C．Cloning technology will be used on humans. D．The six cloned dogs won't live very long.参考答案Ⅰ.1.mirror 2.necessary 3.should4．grades 5.sharingⅡ.6.broke7.loud8.saying9．feel10.kidsⅢ.11.at12.like13.for14.In15．about16.from17.to18.of19．as20.forⅣ.21.As long as22.the same as23．are different from24.bring out25．is similar toⅤ.26.A考查连词短语。
