第一部分选修八Unit2Ⅰ.阅读理解A(2016·上饶市二模) If you've ever had a dog,you know just how deep a connection you can develop with“man's best friend”．But a dog has a much shorter life span(长度)—about12to15years long—than humans,which means every dog owner has to go through the heartbreaking moment when their loving pet passes away.Why not make a clone of that dog then？This is the solution offered by a South Korean company,Sooam Biotech Research Foundation.The company has successfully cloned at least400dogs,mostly for U．S.customers, ever since it pioneered the technique in2005.Now,Sooam Biotech is planning to introduce their business to U．K.dog owners,offering them dogs that look just like their lost ones.Meanwhile,another dog is selected to supply an egg.Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb(子宫)of a female dog.The egg grows into a puppy over the following two months.To clone a dog,researchers first need to take a skin cell from a living dog or one that has just died.The whole process takes less than a day,but it comes at a shockingly high price,around￡63,000(614,000 yuan)．But if you can't afford it now,you can also save the cells in a laboratory and access them at a later date.Just like identical twins of humans,they share the exact same DNA but there will still be small differences between them.“The spots on a Dalmatian clone will be different,for example，”Insung Hwang,head of Sooam Biotech,told The Guardian.However,as magical as cloning might sound,there is no guarantee that the cloned dog will be a perfect replica(复制品)of the original one.Dog owners will also have to accept the fact that personality is not“cloneable”．Apart from genes,personality is also determined by upbringing(培养)and environment,which are both“random elements(因素)that cloning technologies simply cannot overcome”，Professor Tom Kirkwood at Newcastle University,the U．K.,told The Telegraph.Perhaps bringing our dogs back by cloning is not the best way to remember them after all.Kirkwood,a dog owner himself,pointed out:“An important aspect of our relationship with them is coming to terms with the pain of letting go.”文章大意：当你的狗去世的时候，你是否愿意用克隆的方法来得到一只和它一模一样的狗呢？韩国的一家公司现在就在为人们提供这样的服务。
