2016年5月达仁中学高三英语模拟试题 4(时间：100分钟；满分120分)第一部分 阅读理解（共两节，满分40分）第一节 （共15小题，每小题2分，满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。AI was born an albino (白化病人) in Pennsylvania in 1945. No one in my family had ever known what an albino was and what it meant to be an albino.My family and friends treated me like everybody else. That was just about the best thing they could have done. It helped me trust myself, so when troubles came along, I could deal with them.Like most albinos, I had terrible eyesight, but the fact that I could hardly see didnt bother me that much.Kids would tease me, calling me “Whitey”. People stared at me when I held reading material right at the tip of my nose so that I could see it well enough. Even when I was eight, movie-theatre clerks started asking me to pay full price because I “looked older”.The worst part for me was that because my eyesight was so bad, I couldnt play sports very well. I didnt give up trying, though. I shot hoops (投篮) every day. And I studied harder.Eventually, I got better at school and loved it. By the time I got to college, I was double majoring, going to summer school and busying myself with every activity I could find. I had learned to be proud of being an albino. I did my best to make “albino” a positive word. And I decided to make my living with my eyesand in sports.I couldnt see very well to play sports, but with a solid education and a drive to do it, I could make a living involved in the area I loved. Ive done it now for over thirty years in print and in video, and now in cyberspace. People make jokes about how Im the only “blind editor” they know, but the jokes are affectionate, some of them signs of respect.I was just a proud albino kid from the coal country of Pennsylvania. I now realize that being born an albino helped me to overcome difficulties, gain confidence and be proud of my personal achievement.21.

But a dog has a much shorter life spanabout 12 to 15 years longthan 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 least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech is planning to introduce their business to UK 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 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 pricearound 63,000 (614,000 yuan). But if you cant 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 of the original one.Dog owners will also have to accept the fact that personality is not “clone-able”. Apart from genes, personality is also determined by upbringing and environment, which are both “random elements that cloning technologies simply cannot overcome”, Professor Tom Kirkwood at Newcastle University, UK, told The Telegraph.Perhaps bringing our dogs back with 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 comi
