A pill，code-named HT-0712，may make forgetfulness a thing of the past. It is being developed in the US and could go on sale within five years.
According to the newspaper The Sun，the wonder drug has been nicknamed “Mind Viagra”and has already been shown to boost the memory power of mice and flies. Next it will be tested on humans. This is just one of a number of drugs in a pharmaceutical (制药的) race to develop an increased memory pill. At least 12 US companies are believed to be working on similar projects.
Tim Tully，the founder of US drug company Helicon Therapeutics，who is in charge of the HT-0712 project，gave this practical example of its use for students：“If it takes two weeks to memorize a verse of Shakespeare，with one of these drugs you might be able to do it in two or three days. ”
“The memory drug business appears to be set to become a multi-million dollar industry，”experts say. This summer，100 Americans suffering mild memory loss will test HT-0712 in the first experiment on people.
“You don’t think better than you did before，you just get the facts in with less practice. There is a growing belief that memory and memory loss is just another treatable condition，”says Tully.
However，there is some doubt whether the drugs can really improve memory. In a study by the US’s Yale University Medical School，researchers suggested that the drug might affect other parts of the memory.
1.Which of the following can be most likely to replace the underlined word “boost” in the second paragraph?
A.Reduce. B.Increase. C.Kill. D.Harm.
2.What will happen to the students most probably if they take HT-0712?
A.They will grow taller.

A.dim B.uncertain C.bright D.worried
4.HT-0712 is a pill that .
A.has bad effect on the health of mice and flies
B.has been experimented on dozens of animals
C.will be experimented on humans this summer

| A．The great impact and progress in genetic engineering B．Worries about privacy protection C．Worries about medical use of genetic engineering D．Genetic knowledge helps to predict diseases E．Genetic knowledge may not be properly used AB．The application of genetic engineering in the medical fields |
【小题1】__________
Current research into the human gene system is helping us understand why people have predispositions（易患某病倾向）to certain diseases．Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer．Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be．Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings．
【小题2】__________
The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases．Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes （中风）. But with the research that is now being conducted, we may find cures to many more diseases．In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.
【小题3】__________
Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against．Another problem is that many people do not want to discover their weakness．What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?
【小题4】__________
Many people believe that history has not always shown human decision-making to be bright when it comes to ethical（道德的）choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society．
【小题5】．__________
One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious． 查看习题详情和答案>>
