  Trying to Fool the InfertileIt was only eleven years ago that Louise Brown became the first baby to start life outside a mother's womb. Since then,the business of in vitro fertilization - conception in a test tube - has grown even faster than Louise has. Some 200 IVF clinics have sprung up in the U.S.,and they have been responsible for more than 5,000 births. The surging demand stems from the high incidence of infertility:about 1 married couple in 12 has not been able to conceive a child despite a year of trying. IVF dangles one last shred of hope before some of these 2.4 million couples.

  But the procedure remains an expensive long shot,as it fails perhaps 85% of the time. This week the House Subcommittee on Regulation,Business Opportunities and Energy will hold hearings to investigate growing complaints that many heavily promoted IVF clinics misrepresent their success rates. The panel's chairman,Oregon Democrat Ron Wyden,intends to reveal an industry survey showing that the performance of IVF practitioners varies enormously. According to Wyden,half the IVF clinics have yet to achieve a birth,though they may charge up to $ 7,000 for each fertilization attempt. Says the Congressman:"With millions of couples,many of them desperate,spending huge sums of money on technology that has been sold through borderline advertising,you've got a prescription for disaster."

  The top rated clinics can honestly boast that up to 17% of their patients become parents as a result of IVF. But some lesser operations apparently cite similar potential success rates in their come ons,even though their own performance may be far worse. Says Geoffrey Sher,medical director of San Francisco's Pacific Fertility Centers,"The consumer is in the dark. A startling number of programs have never had a single baby born,and they are still quoting statistics." Doctors can start up clinics even if they have little experience or specialized training. "It's very easy for the medical profession to take advantage of infertile couples because they so desperately want children,"observes Carol Peters,chairman of the Texasbased advocates for Parenthood,a political action group.

  Some couples are bitter about their experience with IVF. One 29 year old woman in Dallas underwent several unsuccessful IVF attempts at a total cost of some $17,000. She complains that her doctor never told her that his success rate had dropped from 25% to 5% or that the clinic's new embryologist had never helped produce a birth. Says the woman:" put trust in people,and that doesn't work. I have this desire so bad for a baby,I would do anything to make it work,and I find out I've been ripped off the whole time."

  The industry insists that most customers are not cheated because they are told their chances of having a baby are slim. And many fertility specialists doubt that misleading advertising is as prevalent as Wyden claims. In fact,his assertion that half the clinics have never had a birth may be overstated because at least some of them have not been open long enough for a patient to complete a pregnancy.

  But there is no denying Wyden's contention that the industry has"virtually no oversight." He will soon introduce legislation requiring that IVF labs be certified by the government.  In the meantime,Wyden will publish his survey,listing clinics,the qualifications of their personnel,and their success rate. The report could become a much needed consumer's guide to IVF. In Wyden's view,if a husband and wife put down $ 7,000,they have a right to know what chance they have of getting a joyous return on their investment.

  Ⅱ。 CONTEXTUAL REFERENCE

  Read the following article and figure out the meaning of each word in italics using the context given and wordbuilding skills.

  The world's first test tube baby was born in July,1978 in Britain. Since then about 20 others have been born,mostly in Britain and Australia. And more than 60 women are pregnant and expecting a test tube baby within the next few months.

  Doctors say they have learned a great deal since the first test tube birth. They have made some major improvements in their methods. And they believe the laboratory test tube technique may soon become simple and common.

  The technique is not always successful. Sometimes the egg is not fertilized by the sperm. Often the fertilized egg does not develop in the mother's womb,or it is rejected after a short time.

  Still,the British medical publication  "Lancet" reports that the technique now leads to a normal birth almost 10 percent of the time. Doctors say the test tube technique also appears to be as safe as natural fertilization. Only one test tube baby bas been born with a birth defect. A boy in Australia was born with a heart that will have to be fixed in a medical operation when he is older.

  Doctors believe the laboratory technique offers great hofe to men and women who cannot have babies normally. In the United States,they say it could help as many as 600,000 couples.

  But many persons strongly oppose using the test tube techniques. For example,some American religious leaders charge that the doctors are violating the laws of nature.

  Other opponents note that the world has only limited amounts of food,fuel and other raw materials for its rapidly growing population. Because of this,they say,many nations now have major problems to limit the number of births. And they question that the same time other countries should support programs that increase the number of babies.

  Ⅲ。 CLOZE

  Complete the following passage by filling in the blanks with appropriate words.

  America's first so called test tube baby was born recently. The baby,a girl,   1  more than two and a half kilograms and she is     2      to be in perfect health. Doctors say the     3     is another sign of progress     4     their effort to help men and women     5     cannot have children     6.

  The testtube technique is designed to     7     women who have damaged or     8     Fallopian tubes. These tubes normally     9     the egg cell from a   10   ovaries to the uterus. And normally the male   11   fertilizes the egg when the two cells   12   in the tube.

  In the laboratory test   13   technique doctors first remove an   14   from the mother and keep it for five or six hours   15   a special fluid. Then sperm   16   the father are put    17   the egg. And doctors watch   18    up to one day to see if the egg has  19  fertilized.

  A fertilized egg is kept in the laboratory for up to two days      20     it has divided into four or eight separate cells. Then the egg is returned to the mother's body through the cervix so it can connect to the wall of the womb and develop normally.
