The most compelling evidence of the risks of carcinogenic effects of environmental polluta

The most compelling evidence of the risks of carcinogenic effects of

environmental pollutants comes from animal data, such as the reproductive

failure and anomalous development witnessed in birds and fish exposed to DDT.

Line But can human health effects of a compound be judged without a consensus of

(5) independent epidemiological studies and experimental findings on humans

subjects？ One would argue not, even though increases in breast cancer have

recently been correlated to exposure to environmental pollutants. Scientists

reviewing worldwide morbidities of certain hormonally responsive organs have

found that while the incidence of breast cancer has been increasing, that of

(10) cancer of the uterus, another hormonally responsive organ, has been

decreasing. There is thus no evident increase in uterine cancer that would

support the claim that a pollutant is causally responsible for the recent increase

in breast cancer. It has been suggested that the increase may be the result of

increased diagnosis, and geographical differences in cancer susceptibility are so

(15) large that the currently available statistics do not permit a definite conclusion.

The primary purpose of the passage is to treat the potential correlation between environmental pollutants and carcinogenic effects in which of the following ways？

A．Explicate the reasons it has been suggested

B．Suggest an alternative correlation

C．Examine its possible implications

D．Criticize the evidence used to support it

E．Present findings that qualifies it

第2题

One of the most strikingly apparent instances of extrasensory perception is the precogniti

ve experience, when a person has a compelling perception of a coming disaster, news of death of a loved one, or a communication from a long-lost friend, and the predicted event then happens. Many who have had such experiences report that the emotional intensity of the precognition and its subsequent verification provide an overpowering sense of contact with another realm of reality. I have had such an experience myself. Many years ago, I awoke in the middle of night in a cold sweat, with a certain knowledge that a close relative had suddenly died. I was so gripped with the haunting intensity of the experience that I was afraid to place a long-distance phone call, (for fear that the relative would trip over the telephone cord or something and make the experience a self-fulfilling prediction). In fact, the relative is alive and well, and whatever psychological roots the experience may have, it was not a reflection of an imminent event in the real world.

However, suppose the relative had in fact died that night. You would have had a difficult time convincing me that it was merely coincidence. But it is easy to calculate that if each American has such a premonitory experience a few times in his lifetime, the actual statistics alone will produce a few apparent precognitive events somewhere in America each year. We can calculate that this must occur fairly frequently, but to the rare person who dreams of disaster, followed rapidly by its realization, it is uncanny and awesome. Such a coincidence must happen to someone every few months. But those who experience a correct precognition understandably resist its explanation by coincidence.

After my experience I did not write a letter to an institute of psychology relating a compelling predictive dream that was not borne out by reality. That is not a memorable letter. But had the death I dreamt actually occurred, such a letter would have been marked down as evidence for precognition. The hits are recorded; the misses are not. Thus human nature unconsciously conspires to produce a biased reporting of the frequency of such events.

"Precognitive experience" most probably means ______

A．some kind of disaster a person experienced in his childhood

B．a vague sense that something will happen and it does happen later

C．the prediction of the death of a close friend

D．uncertainty about an impending accident

Juries in criminal trials do not base verdicts on uncorroborated testimony given by any on

e witness. Rightly so, because it is usually prudent to be highly skeptical of unsubstantiated claims made by any one person. But then, to be consistent, juries should end an all-too-common practice: convicting defendants on the basis of an uncorroborated full confession. Which of the following, if true, most strengthens the argument above？

A．Juries often acquit in cases in which a defendant retracts a full confession made before trial.

B．The process of jury selection is designed to screen out people who have a firm opinion about the defendant" s guilt in advance of the trial.

C．Defendants sometimes make full confessions when they did in fact do what they are accused of doing and have come to believe that the prosecutor has compelling proof of this.

D．Highly suggestible people who are accused of wrongdoing sometimes become so unsure of their own recollection of the past that they can come to accept the accusations made against them.

E．Many people believe that juries should not convict defendants who have not made a full confession.

Birds do it. Chimps do it. Many humans even do it. The pass of food from 【M6】______ one creature to another is certainly an intimate form. of interaction.

The science of kissing is a fascinated thing to think about and 【M9】______ Philematology(the science and study of kissing)is becoming an increasingly popular area of study, for researchers strive to sort out 【M10】______ the mysteries of love and attraction. Though plenty of unanswered questions remain, perhaps its sufficient to say that kissing remains an excellent and exciting human pastime.

After dithering about like this in the cold for two or three minutes, Billy decided that he would walk on and take a look at The Bell and Dragon before making up his mind. He turned to go. And now a queer thing happened to him. He was in the act of stepping back and turning away from the window when all at once his eye was caught and held in the most peculiar manner by the small notice that was there. BED AND BREAKFAST, it said. BED AND BREAKFAST, BED AND BREAKFAST, BED AND BREAKFAST. Each word was like a large black eye staring at him through the glass, holding him, compelling him, forcing him to stay where he was and not to walk away from that house, and the next thing he knew, he was actually moving across from the window to the front door of the house, climbing the steps that led up to it, and reaching for the bell. He pressed the bell. Far away in a back room he heard it ringing, and then at once —it must have been at once because he hadn’t even had time to take his finger from the bell button—the door swung open and a woman was standing there. Normally you ring the bell and you have at least a half-minute’s wait before the door opens. But this dame was like a jack-in-the-box. He pressed the bell—and out she popped! It made him jump.

A、mystery

B、animal story

C、romance

D、historical narrative

第7题

It was about 2 p.m. on Mar. 9 when three Nucor Corp. electricians got the call from their

colleagues at the Hickman (Ark.) plant. It was bad news: Hickman's electrical grid had failed. For a minimill steelmaker like Nucor, which melts scrap steel from autos, dishwashers, mobile homes, and the like in an electric arc furnace to make new steel, there's little that could be worse. The trio immediately dropped what they were doing and headed out to the plant.

No supervisor had asked them to make the trip, and no one had to. They went on their own. There wasn't any direct financial incentive for them to blow their weekends, no extra money in their next paycheck, but for the company their, contribution was huge.

What's most amazing about this story is that at Nucor it's not considered particularly remarkable. "It could have easily been a Hickman operator going to help the Crawfordsville [Ind. ] mill," says Executive Vice-President John J. Ferriola "It happens daily." Nucor has nurtured one of the most dynamic and engaged workforces around. The 11 300 nonunion employees at the Charlotte (N. C. ) company don't see themselves as worker bees waiting for instructions from above. Nucor's flattened hierarchy and emphasis on pushing power to the front line lead its employees to adopt the mindset of owner-operators.

Nucor gained renown in the late 1980s for its radical pay practices, which base the vast majority of most workers' income on their performance. An upstart nipping at the heels of the integrated steel giants, Nucor had a close-knit culture that was the natural outgrowth of its underdog identity. Legendary leader F. Kenneth Iverson's radical insight: that employees, even hourly clock-punchers, will make an extraordinary effort if you reward them richly,treat them with respect ,and give them real power.

Nucor is an upstart no more, and the untold story of how it has clung to that core philosophy even as it has grown into the largest steel company in the U, S. is in many ways as compelling as the celebrated tale of its brash youth. Iverson retired in 1999.

Under CEO Daniel R. DiMicco, a 23-year veteran, Nucor has snapped up 13 plants over the past five years while managing to instill its unique culture in all of the facilities it has bought, an achievement that makes him a more than worthy successor to Iverson.

For a steel maker like Nucor Corp, the electric grid of which ______.

A．fails frequently

B．seldom fails

C．can not bear failure

D．affect little when fails
