It might be flattering(讨人喜欢的 ), but how would you feel about having a little brother or sister who is also your twin? A laboratory experiment conducted last fall suggests
8、 it may someday be possible. For the first time ever, scientists made exact copies, or clones(克隆 ), of a human embryo. Although the embryos grew for only six days, cloned embryos could theoretically be implanted in a womans womb(子宫 )and develop into normal babies. Or they could be frozen and implant
9、ed years later. The scientists developed their cloning technique to make it easier for childless couples to have babies by in vitro(在体外的 )fertilization. In this procedure, sperm(精子 ) from the man fertilizes an egg from the woman in a laboratory dish. In most case, doctors must try implanting several
10、 embryos before one stays in the womb.Cloned embryos would give them many more embryos to implant. But the technique could also be used for other purposes. Parents might freeze embryos cloned from their children so that they could be replaced if any of them died.The clones would also be ideal donors
11、 if the children needed organ transplants. Another possibility: Childless couples could go to a bank of frozen embryos and choose a child just like one whos already living. Some people are concerned that these couples might pick only beautiful, successful children. The ethical dilemmas(困境 )of clonin
12、g have not yet been discussed fully because the public assumed it was a long way off.

Most antibiotics are used by physicians to fight various diseases caused by harmful microbes. A few are
17、 used to treat certain cancers. Antibiotics are sometimes called“ wonder drugs because they can cure many diseases that once were often fatal. The number of deaths that are caused by pneumonia and scarlet fever has declined drastically since people began using antibiotics. 2. There are more than 70
18、clinically useful antibiotics, Antibiotics fight pathogenic microbes and cancer cells by interfering with their normal cell processes. In most cases, this interference can occur in one of three ways: prevention of cell wall formation, disruption of the cell membrane, and disruption of chemical proce
19、sses. 3. The contents of bacterial cells are enclosed in a membrane that is surrounded by a rigid wall that prevents the cells from splitting open. Penicillins and some other antibiotics destroy pathogenic microbes by hindering the formation of this wall. Human cells do not have nor need rigid cell
20、walls and so are not damaged by these antibiotics. 4. Some antibiotics, including nystatin, disrupt the cell membrane of certain microbes. This membrane controls the movement of materials in and out of the cell. If the membrane is disrupted, vital nutrients may escape from the cell, or poisonous sub
21、stances may enter and kill the cell. But the membranes of human cells are not affected because these antibiotics disrupt cell membranes that contain elements found only in microbial cells. 5. All cells produce proteins and nucleic acids, which are vital to the life of any organism. Some antibiotics
22、fight disease by interfering with the chemical processes by which these substances are produced.For example, streptomycin prevent certain kinds of microbes from producing proteins, and rifampin interferes with the formation of nucleic acids. Human cells produce proteins and nucleic acids in much the
23、 same way that microbial cells do. But these processes differ enough so that some antibiotics interfere with chemical activities in microbial cells but not in human cells. 23 A. Autibiotics destroy pathosenic microbes by preventing the formation of the walls surrounding the membranes of the microbia
24、l cells that prevent the cells from split- ting open. B. More than 70 clinically useful antibiotics have been in- vented to fight pathogenic microbes and cancer cells by interacting with their normal cell processes. C. Human cells are not surrounded by a membrane D. Some antibiotics disrupt the cell
25、 membrane of certain microbes, letting vital nutrients to escape form the cell or poisonous substances to enter and kill the cell. E. Nystatin is used to disrupt the wall surrounding the membrane. F. Some antibiotics fight disease by interfering with chemical activities in microbial cells but not in

Other researchers previously succeeded in using similar techniques to produce pote
