Reading Comprehension
Cloning technology made its first leap from science fiction to science fact in 1997. That year, Scottish researcher lan Wilmut created the world's first animal clone:a sheep named Dolly. In making Dolly, Wilmut defied(对…挑战) nature because Dolly was produced without the union of male and female sex cells.
The method that Wilmut used to create Dolly is neither a top-secret nor hard to understand. First, he removed an egg cell from an adult female sheep. Then, he used a fine needle to suck out(吸出) the egg' s nucleus(细胞核), the structure that houses a cell' s DNA(deoxyribonucleic acid(脱氧核糖核酸). DNA contains the biological material that determines what an organism looks like and how it functions.
Next, Wilmut removed a skin cell from another sheep-the sheep he wished to copy. Placing the empty egg cell and the skin cell side by side, he forced the two cells to fuse by zapping(用辐射线照射) them with a charge(电荷) of electricity. By doing that, Wilmut created an egg from one animal that contained the DNA of another.
The new egg cell divided and developed into an embryo(胚胎). Wilmut then implanted(移植) the embryo in he womb(子宫). In time, the embryo developed into a lamb sheep-Dolly.
For years later, a whole barnyard of animal clone, including sheep, mice, cows, pigs, and goats, has, come to life in labs around the globe. Now, the race is on how to produce the first human clone although many people are strongly against it.

Newton was a great English scientist. He always gave all his attention (注意)to his work. One morning he got up very early because he was working on a very difficult problem. As he was thinking hard about the problem, he didn't go to have his breakfast. His servant Mary thought he needed food, so she brought an egg and a pan (锅子)of water to his room. But Newton wanted to be alone."Plase leave the egg and I will boil(煮)it," he said. The servant put the egg on the table by the side of Newton's watch and said," Please boil the egg for four minutes and it will be ready." Then she left the room. When she returned about an hour later, Newton was standing by the fire-place(壁炉). He had put the watch in the pan and was holding the egg in his hand. He didn't know that he had made a terrible mistake.
