Does Genetic Research Threaten Our Civil Liberties?

The Current Genetic Research

The science of genetics is a flourishing new industry, nourished in large part by the federally funded Human Genome Project. The goal of this ambitious research endeavor is to identify every gene found in the human body, perhaps 100,000 in all. Several months ago, the U.S. government and a private corporation announced that they had "completed" the "map" of the genome, although actually there are still many gaps. Much related research focuses on genetic diagnostics-- tests designed to identify genes thought to be associated with various medical conditions. More than 50 new genetic tests have been identified in the past five years alone.

The increasing speed, sophistication, affordability, and interconnectivity of computer systems allow the rapid monitoring and matching of many millions of records. A 1994 benchmark study by the ACLU found that "concerns about personal privacy run deep among the American people".

The promotion of an ideology of geneticization fosters the belief that genes are determinative of an individual's behavior, character, and future. Capitalist economic relations have created a scramble (争夺) for venture capital, the altering of patent laws, and calls for mass genetic testing by researchers who trade on the old image of the altruistic scientist to mask their conflicts of interest in testing labs, patents, consulting contracts, etc.

The Technological Society

Technologies are not value-neutral; they usually embody the perspectives, purposes, and political objectives of powerful social groups. The dominant ideology in Western society proclaims that science and technology are value-neutral, and the only problems caused by technologies are either "externalities" (unintended side effects) or abuses. However, because technologies are the result of human interventions into the otherwise natural progression of activities (and not acts of God or of nature), they are themselves actually imbued with human intentions and purposes. Current technologies do not equally benefit all segments of society (and indeed are not intended to do so), although to maximize public support for these developments and to minimize potential opposition, their proponents rarely acknowledge these distributional ramifications (分歧).

The United States is a society in which the differential access to wealth and power has been exacerbated during recent years. Thus, those people with more power can determine the kinds of technological developments that are researched and implemented. Because of their size, scale, and requirements for capital investments and for knowledge, modem technologies are powerful interventions into the natural order. They tend to be the mechanisms by which already powerful groups extend, manifest, and further consolidate their powers. Thus, technologies themselves are not neutral; they are social and political phenomena. Genetic technologies and computerization exhibit these characteristics, and reflect power differentials in the society.

The results of technological advancement appear to offer a good future capabilities of enhanced surveillance (监视) and control over people and events, as well as promises of perfectionism (thus leading to both a loss of privacy and increased opportunities for discrimination by powerful entities). Predictability will replace a tolerance for natural variation and diversity.

Loss of Privacy

Genetic privacy, like medical privacy in general, involves notions of the dignity and integrity of the individual. Is data accurate? Can individuals access their own files? Can the donor correct inaccurate data? Are the custodians faithful and are technical security systems protecting the data where possible? Does the individual have control over which third parties are allowe

If you go down to the woods today, you may meet high-tech trees genetically modified to sp
eed their growthor improve the quality of their wood. Genetically-engineered food crops have become increasingly common, albeit controversial. over the past ten years. But genetic engineering of trees has lagged behind.

Part of the reason is technical. Understanding. and then altering, the genes of a big pine tree are more complex than creating a better tomato. While tomatoes sprout happily, and rapidly, in the laboratory, growing a whole tree from a single, genetically altered cell in a test tube is a tricky process that takes years, not months. Moreover. little is known about tree genes. Some trees, such as pine trees. have a lot of DNA-roughly ten times as much as human. And, whereas the Human Genome Project is more than half-way throughits task of isolating and sequencing the estimated 100,00 genes in human cells. similar efforts to analyzetree genes are still just saplings (幼苗).

Given the large number of tree genes and the little that is known about them, tree engineers are starting with a search for genetic "markers". The first step is to isolate DNA from trees with desirable propertiessuch as insect resistance. The next step is to find stretches of DNA that show the presence of a particular gene. Then, when you mate two trees with different desirable properties, it is simple to check which offspring contain them all by looking for the genetic markers. Henry Amerson, at North Carolina State University, is using genetic markers to breed fungal resistance into southern pines. Billions of these are grown across America for pulp and paper, and outbreaks of disease are expensive. But not all individual trees are susceptible. Dr. Amerson’s group has found markers that distinguish fungus-resistant stock from disease-prone trees.Using traditional breeding techniques, they are introducing the resistance genes into pines on test sites in America.

Using generic markers speeds up old-fashioned breeding methods becauseyou no longer have to wait for the tree to grow up to see if it has the desiredtraits. But it is more a sophisticated form. of selective breeding. Now. however.interest in genetic tinkering (基因修补) is also gaining ground. To this end, Dr.Amerson and his colleagues are taking part in the Pine Gene Discovery Project. an initiative to identify and sequence the 50,000-odd genes in the pine tree&39;s genome. Knowing which gene does what should make it easier to know what to alter.

Oscar and Jack are identical twins, separated when they were babies by their parent'
s divorce.Jack was brought up by their Jewish father in Trinidad, Oscar went to live with their mother's family in Czechoslovakia.In fact Oscar did not know he was Jewish until Jack found him in Germany in 1954.Jack is proud to be a Jew, but Oscar still does not like to talk about his Jewish heritage.Yet the twins are similar in many ways.They both like spicy food and sweet drinks.In school they both did well in sports but poorly in mathematics.

Are thoughts and behavior. determined by heredity (遗传) or by environment? Social scientists have long been interested in this question; the results of "twin studies" are particularly interesting to them.Twin studies of the similarities and differences between twins.There are two types of twins: identical twins, who look exactly the same because they have identical genetic characteristics, and fraternal twins, who have different genetic characteristics.In a 1937 study, Newman, Freeman, and Halzinger found that identical twins are more similar in height and weight than fraternal twins.Because identical twins have the same genetic characteristics, the conclusion was that size is determined more by heredity than by environment.In 1962, James Shields compared the height, weight, and intelligence of identical twins who were brought up together (in the same environment) with those of identical twins brought up apart (in different environments).He found that although the differences were small, identical twins who were brought up together were more similar than those brought up apart.Shields concluded that height, weight, and intelligence are largely determined by heredity.However, because of the differences between identical twins brought up together and those brought up apart, these characteristics may be partly determined by environment.

In the case of Oscar and Jack, heredity seems to determine physical and mental abilities, tastes, and behavior.Environment seems to determine thought.

1.After their parents' divorce, Oscar and Jack ______.

A.went to live with their mother's family

B.were brought up by their father

3.Identical twins are more similar than fraternal twins because_______.

A.they have the same mother

B.they have the same genetic characteristics

C.they were brought up together

D.they were born at the same time

4.The conclusion of Newman, Freeman and Halzinger's 1937 twin study was that_______.

A.size is determined by height, weight, and environment

B.identical twins are taller and heavier than fraternal twins

D.identical twins are more similar than fraternal twins

5.Shield drew a slightly different conclusion from his study because_______.

A.he also compared the intelligence of the twins in his study

B.he compared twins brought up together with those brought up apart

C.only identical twins were included in his study

D.all of the environment factors were carefully controlled

听力原文:For most people, reading a newspaper has become a habit passed down from generati

听力原文: For most people, reading a newspaper has become a habit passed down from generation to generation. I'm sure in a hundred years we will still be reading newspapers.

What basically makes news is what affects our lives — the big political stories the coverage of the wars, earthquakes and other disasters will continue much the same. I think there will be more coverage of scientific research, though. It's already happening in areas that may directly affect our lives, like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are.

It's quite possible that in the next century newspapers will be transmitted electronically from Fleet Street and printed out in our own home. In fact, I'm pretty sure that is how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read.

I think people have got it wrong when they talk about the competition between the different media. They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it's never really pleasant to read something just on a screen.

Questions 29 to 31 are based on the passage you have just heard.

29. What does the speaker say about news in the future?

30. What will probably be on in the newspaper made by yourself?

31. What does the speaker think of different media?

(30)

A.It will cover more big political affairs.

B.It will cover less disasters.

C.It will cover more scientific research.

D.It won't be printed in publishing houses.

The Power of Words: Advertising Tricks The effect that words can have is incredible: to in

The Power of Words: Advertising Tricks

The effect that words can have is incredible: to inform, persuade, hurt or ease pain, end war or start one killing thousands or even millions of people. They can get your point across, or destroy any hope of your ideas ever being understood. A major element of advertising is the words, which ones and in what order. The following is several of the specific tricks that are commonly used in advertising.

Black/White Trick

The black/white, or either/or, trick is making a statement that provides insufficient options to your argument. "Love it or leave it" was a big slogan of the 1960s, and it sounds logical. Nevertheless, it provides no other possible options, such as" Love it, or don't love it, stay or not, you don't have to agree with me if you don't want to. "

The reason this fallacy is often called the black/white fallacy is that it denies any other choices on an issue or idea. Using it gives the impression that everything can be seen in terms of yes or no, true or false, on or off, with no maybes or both true and false depending on circumstances allowed. This fallacy is particularly popular and effective in slogans like" Love it or leave it", "If you're not for me, you're against me", "My country, right or wrong". Note that all of the above actually have other options, but the statements do not allow for them.

A common way in which this trick is used in advertising is by presenting two situations, one with the product and 'the other without. The one with the product shows circumstances that the advertiser presumes the target audience would like to be in, and vice versa for the situation without the product. For example, you have two groups of people: the first is young, beautiful, fit, happy, fun-loving and active; the second is old, ugly, miserable, and passive. The first uses the product; the second doesn't. The assumption is that the purchase of the product makes you a member of the first, that the absence of the product makes you the second. Since most people would rather be the first, and the product is a part of being the first, then people should buy the product. And they do.

Genetic Fallacy

The genetic fallacy makes a prediction about something based on where it came from or its origins. For example, saying" He wouldn't do that--he's from a good family" is making a genetic fallacy. "You can't expect any better from her--she's from the slums" is also using a genetic fallacy. Note that in neither case is there any reference to the individual's personal abilities or lack thereof; only to where they came from. In advertising, this fallacy is used often: "If it's made by [company],it must be good" is an example.

Weasel(含糊其辞的)Words

Weasel words are those words that are tossed into a sentence that change the actual meaning of the sentence while leaving an impression that is different. It's the easiest way to avoid having to take any responsibility for anything you say, or seem to say. For example, the sentence "Our canned corn is as good as fresh cooked corn". The impression given is that the canned corn is as good (whatever that means) as corn on the cob(玉米穗轴) right off the stalk. However, the phrase contains a weasel word:" cooked". Thus, the sentence actually says that the canned corn is as good as corn that has been cooked; now you need to cook it again to serve it. Note the sentence does not say that the canned corn is as good as fresh corn; it's as good as fresh cooked corn.

A favorite weasel word is one of the shortest: if. "If the whole wide world can enjoy [use, buy, desire, etc.] [whatever the product is], then so can you" says absolutely nothing about the product, or even if anyone at all enjoys [uses, buys, desires, etc.] the product. It simply says "if", applied to a totally hypothetical, nonexistent state of being.
