Any normal species would be delighted at the prospect of cloning. No more nasty surprises

like sickle cell or Down syndrome—just batch after hatch of high-grade and, genetically speaking, immortal offspring! But representatives of the human species are responding as if someone had proposed adding Satanism to the grade-school Curriculum. Suddenly, perfectly secular folks are throwing around words like sanctity and retrieving medieval-era arguments against the pride of science. No one has proposed burning him at the stake, but the poor fellow who induced a human embryo to double itself has virtually recanted—proclaiming his reverence for human life in a voice, this magazine reported", choking with emotion".

There is an element of hypocrisy to much of the anti-cloning furor, or if not hypocrisy, superstition. The fact is we axe already well down the path leading to genetic manipulation of the creepiest sort. Life-forms can be patented, which means they can be bought and sold and potentially traded on the commodities markets. Human embryos are life-forms, and there is nothing to stop anyone from marketing them now, on the same shelf with the Cabbage Patch dolls.

In fact, any culture that encourages in vitro fertilization has no right to complain about a market in embryos. The assumption behind the in vitro industry is that some people's genetic material is worth more than others' and deserves to be reproduced at any expense. Millions of low-income babies die every year from preventable ills like dysentery, while heroic efforts go into maintaining yuppie zygotes in test tubes at the unicellular stage. This is the dread "nightmare" of eugenics in familiar, marketplace form—which involves breeding the best-paid instead of the best. Cloning technology is an almost inevitable byproduct of in vitro fertilization. Once you decide to go to the trouble of in vitro, with its potentially hazardous megadoses of hormones for the female partner and various indignities for the male, you might as well make a few backup copies of any viable embryo that's produced. And once you've got the backup organ copies, why not keep a few in the freezer, in case Junior ever needs a new kidney or cornea?

The critics of cloning say we should know what we're getting into, with all its Orwellian implications. But if we decide to outlaw cloning, we should understand the implications of that. We would be saying in effect that we prefer to leave genetic destiny to the crap shooting of nature, despite sickle-cell anemia and Tay-Sachs and all the rest, because ultimately we don't trust the market to regulate life itself. And this may be the hardest thing of all to acknowledge, that it isn't so much 21st century technology we fear, as what will happen to that technology in the hands of old-fashioned 20th century capitalism.

We learn from the first paragraph that

A.nonreligious folks received cloning with open arms.

B.the scientist was encouraged to popularize his ideas;

C.some people moved strongly against cloning technique.

D.a technician was condemned and sentenced to death.

第1题
Natural selection describes the biological process in which the differences of individuals
within a population influences their abilities to survive and reproduce in an environment. The differences in individuals is a result of their genetic inheritance from their parents. In a population, any characteristic which blocks reproduction success tends to decrease generation by generation. In time, the ill-adapted die out. On the other hand,the individuals who do survive and reproduce will tend to produce offspring which are better adapted to the environment. Natural selection tends to promote adaptations that will increase the organism's ability to survive in an environment.

Natural selection can serve to stabilize a population if the new traits, called mutations, are eliminated when they appear because they are not as well-adapted to the environment. The opposite effect is obtained when a new trait is introduced which allows individuals to adapt better over time, the species will change as this mutation becomes more widespread in the population. In human beings, increased brain size helped individuals to adapt better, and so brain size increased gradually in the species. Changes in the overall genetic makeup of a population are normal when there are environmental changes, especially sever environmental disruptions. Specialized adaptations to specific environments can lead, over time, to the development of subpopulation of individuals, ones who are better adapted to particular soil conditions food sources and so on. Given enough time, these subpopulations may develop into separate species, such as zebras and horses, living in distinct environments and not interbreeding.

Individuals in a population differ from one another because______.

A.they have different success generation by generation

B.they are ill-adapted and eventually die out

C.they have different genetic inheritances

D.they want to survive and reproduce successfully

改错:We use language every day

We use language every day. We live in a world of words. Hardly any moment passes with someone talking, writing or reading. Indeed, __1__languages is most essential to mankind. Our lives increasingly depend on fast and successful use of language. Strangely enough, we know __2__more about things around us than on ourselves. For example, language __3__is species specific, that is, it is language that differs human from __4__animals. However, we do not know yet how exactly we inquire language __5__and how it is possible for us to perceive through language; nor we __6__understand precisely the combinations between language and thought, __7__language and logic, or language and culture; still less, how and when language started. One reason for this inadequate knowledge of language is that we, like language users, take too many things for granted. __8__Language comes to every normal person so naturally that a few __9__

of us stop to question what language is, much less do we feel the necessity to study it. Language is far more complex than most people have probably imagined and the necessity to study it is far greater than some people may have assured. Linguistic is a branch of science which __10__takes language as its object of investigation.

听力原文:W: Well, it's sort of attractive, but in the end I still find it a pretty depress
ing place.

M: Do you? Why?

W: The animals are out of their natural environment. They're just here for humans to look at. There's nothing natural about it.

M: Yeah, but if we didn't have any zoos, a lot of species would just, well, they'd face extinction.

W: Do you really believe that?

M: Well, don't you? I mean they have good breeding projects for some species that are dying out. Um, anyway, I think, there's a trend towards developing zoos to become education centers, stimulating information for kids and displays, and that kind of thing.

W: What we need to do is to take care of the natural environment, make sure that they've still got a place where they can live in the wild.

M: Well, yeah, OK. But it's just not happening, is it? I think in reality you've got to have zoos.

W: Well, I just can't agree with that. I mean, what is the pleasure in watching animals pacing up and down in cages?

M: Look, zoos are changing. Some older zoos put animals in cages, but what about safari parks? The animals are fine there. They've got a lot of space and people see them in a much more natural setting.

W: Well, maybe you're right.

What are the man and woman talking about?

A.About the building of the zoo.

B.About the lay-out of the zoo.

C.About the function of the zoo.

D.About the attractiveness of the zoo.

听力原文:W: I would like to have a dog of my own.Do you have any ideas of dogs?M: Oh, dogs

听力原文:W: I would like to have a dog of my own. Do you have any ideas of dogs?

M: Oh, dogs are social animals and without proper training, they will behave like wild animals.

W: It sounds terrible. How will they behave when they are not properly trained?

M: They will spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you.

W: Then I dare not keep the dog at my home.

M: Don't be so scared. The key to preventing or treating behavior. problems is learning to teach the dog to redirect its normal behavior. to outlets that are acceptable in the domestic setting.

W: Would you please offer me some suggestions on training dogs?

M: Certainly. One of the best things you can do for your dog and yourself is to train it to obey you. Obedience training doesn't solve all behavior. problems, but it is the foundation for solving just about any problem.

W: Is there any other significance of training?

M: Yes. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.

W: Oh, the relationship between people and dogs seems very important.

M: You are right.

A.Dogs are social animals.

B.Dogs are wild animals.

C.Dogs can bite their owners.

D.Dogs can obey to their owners if properly trained.

第9题
Naturally, in a group of animals as diverse as the snakes, and with so many varied enemies
, there are numerous defensive reactions and devices. There is, however, one general pattern of hehaviour, in the presence of a suspected enemy the first reaction is to try to escape observation; if this fails, the next resort is flight to some inaccessible retreat, but if this is not possible, or is circumvented, various kinds of intimidatory gestures and warning devices arc brought into play ;in the last resort the snake attacks. This pattern varies with the circumstances; some stages may be omitted or combined unpredictably whilst some notoriously irascible species may dispense with all the preliminaries and attack almost at once, though seldom or never without some provocation. The difficulty is to know what constitutes provocation, a matter that is apt to be debatable in other fields!

Amongst the factors that increase aggressiveness are hunger, the mating season and surprise, with the last mentioned the commonest ; when hunting for food or for mates, activity and the aggressive instinct are both at their peak, but it is when it is caught unawares that the normal chain of re- actions tends to become telescoped. Owing to their poor sense of hearing, snakes are very liable to be, quite literally, caught napping and a similar situation arises during their periods of temporary blindness just before sloughing begins. By far the greatest number of snake-bite accidents result from the unwitting disturbance of resting snakes, and this hazard is much increased with species that are well camouflaged and whose natural instinct is to trust to this concealment as their principal defence. As well as differences in aggressiveness between individuals of the same species according to the circumstances and conditions, there are also notable differences between species ,even closely allied species; and the reports of those who have been attacked may understandably be lacking in objectivity. So it is impossible to forecast, even in outline, how any encounter will develop.

The Hamadryad, for example,is usually credited with being amongst the most aggressive of snakes ,and there are many accounts of unprovoked attacks ;yet on one occasion fourteen men and seven dogs passed and returned within two yards of a nest and no snake was seen although the fe- male, which guards the nest, could not have been far. away.

One very well-known student of snakes once parked his car under some trees near Nairobi and on his return found a small green snake on it. Being preoccupied at the moment he gave it only a cursory glance and, thinking it was a common harmless tree-snake, bundled it unceremoniously into his pocket ;it was, as he later discovered to his horror, a young Green Mamba, but it made no attempt to bite despite the rough treatment it had received.

The proportion of the snakes of the world that have some forms of procrypsis(i. e. resemblance to the background)is very high, but the frequency with which the resemblance results in accidents suggests that it is incorrect to regard it as primarily a "protective" device. There is every advantage to a predatory animal in being unobserved until its prey comes within striking distance, but it is distinctly hazardous to allow an enemy to approach closely with the hope ,but no certainty, of remaining undetected. The commonest type of proerypsis is the result of colours that harmonize with hose of the normal background, associated with patterns that disrupt the animal' s outline or produce "counter shading" whereby those parts of the body that will be seen in shadow and appear dark, are lighter in colour whilst highlight areas are dark-coloured.

The snake's general pattern of behaviour in defence suggests that______.

A.when in doubt, it will attack

B.it will usually do its best to avoid trouble

C.attack is its chief form. of defence

D.it is completely unpredictable

听力原文:M: Hello. This is Greg Rice reporting live in Barrow, Alaska.

W: Hello, Greg. Is everything going smoothly?

M: Yes. I've just arrived here in Barrow, Alaska, to bring you live coverage of what appears to be the results of a huge meteorite impact, perhaps the largest in recent history, that occurred just twelve hours ago. The exact location of the impact is unknown, but estimates put it about 20 kilometers south of Barrow based on shock waves felt throughout the region.

W: Are there any witnesses?

M: Yeah. Some witnesses say they saw a bright light streaking through the sky, accompanied by a roaring boom, moments before the impact. It's unknown whether there are any casualties, but it is unlikely considering this sparsely populated area.

W: It's said that such impacts were commonplace during the formation of our solar system, and many believe that a meteorite 10 kilometers in diameter which crashed into Earth 65 million years ago led to the mass extinction of many animal species including the dinosaurs.

M: You're right. But it is often difficult to calculate the number of such large impacts on Earth because erosion and vegetation make it difficult to spot them. In recent years, astronomers have focused more of their attention on the paths of many uncharted space rocks or asteroids floating out there in the hope that we might be able to determine the threat they pose on mankind...This is Greg Rice reporting from Alaska.

W: Thanks, Greg...We'll keep you up-to-date on any development there.

(23)

A.An alien spacecraft landing.

B.The impact of a meteorite.

C.A volcanic eruption.

D.The blizzard conditions in Alaska.
