The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect. According to a newly published study，cats seem to be able to predict the location of hiding prey （猎物） using both their ears and an inborn （天生的） understanding of how the physical world works. In a recent experiment，Japanese researchers taped 30 domestic cats reacting to a container that a team member shook.Some containers rattled （发出响声）；others did not.When the container was tipped over，sometimes an object fell out and sometimes it didn't. It turns out that the cats were remarkably smart about what would happen when a container was tipped over.When an object did not drop out of the bottom of a rattling container，they looked at it for a longer time than they did when the container behaved as expected. "Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects，" lead researcher Saho Takagi says in a press release.The researchers conclude that cats' hunting style may have developed based on their common-sense abilities to infer where prey is，using their hearing. Scientists have explored this idea with other lovely creatures；babies.Like cats，babies appear to engage in what's called "preferential looking" — looking longer at things that are interesting or unusual than things they perceive as normal. When babies' expectations are disturbed in experiments like the ones performed with the cats，they react much like their animal friends.Psychologists have shown that babies apparently expect their world to be consistent with the laws of physics and cause and effect as early as two months of age. Does the study mean that cats will soon grasp the ins and outs of cause and effect？Maybe.Okay，so cats may not be the next physics faculty members at America's most important research universities.But by demonstrating their common sense，they've shown that the divide between cats and humans may not be that great after all.（1）What do we learn from a newly published study about cats？ ____ A．They can be trained to understand the physical world.B．They know what kind of prey might be easier to hunt.C．They have a natural ability to locate animals they hunt.D．They are capable of telling which way their prey flees.（2）What may account for the cats' response to the noise from the containers？ ____ A．Their inborn sensitivity to noise.B．Their unusual sense of direction.C．Their special ability to perceive.D．Their mastery of cause and effect.（3）In what way do babies behave like cats？ ____ A．They focus on what appears odd.B．They view the world as normal.C．They do what they prefer to do.D．They are curious about everything.（4）What can we conclude about cats from the passage？ ____ A．They have higher intelligence than many other animals.B．They interact with the physical world much like humans.C．They display extraordinarily high intelligence in hunting.D．They can aid physics professors in their research work.

For taking super-sharp pictures of space, the best telescope is the Hubble, in orbit above the earth. But astronomers can't use it whenever they like; they have to bid for time on the already over-burdened instrument. After about 2010, when the aging Hubble starts to fail, astronomers won't be able to go to it at all. That's why space watchers are always looking for clever ways to take super-clear images from the ground without the blurring of the atmosphere. And it's why a recent piece of news from Cambridge University and Caltech made scientists take notice. By wedding a new electronic light detector to the Hale Telescope in California, astronomers were able to snap at least one space photo that was literally twice as sharp as a comparable Hubble image and 50,000 times cheaper. The concept behind the detector (探测器), which is known, cutely, as the Lucky Camera, is very simple: The earth's altering atmosphere acts as a lens, which changes moment by moment as pockets of warmer or cooler air constantly pass in front of a given object. That's why stars blink and why telescopes on the ground can be only so sharp. The stars blink for the Lucky Camera too. So the computer that runs the Lucky Camera saves those rare, perfect images instead of the rest. And because a single 1⁄20-second exposure of an object in space is almost invisible, the computer combines the good images and produces one that could be used. Still, the Lucky Camera isn't a true replacement for the Hubble. Since it has to throw away most of its images, it isn't very efficient. Yes, it took a picture sharper than the Hubble could, but it took a lot longer. The instrument is also limited to a patch of sky only about 1⁄120th the width of the full moon; the Hubble's field of view is 150 times as large. And the Hubble can see ultraviolet (紫外线) and infrared (红外线) light, which the atmosphere blocks. Ultimately, says Mackay, "we're not competing with the Hubble. We're simply trying to provide another choice when the Hubble dies."1. Why can't the Hubble satisfy the need of astronomers?A) Because it has been overburdened and becomes unavailable. B) Because it flies too far away for astronomers to go onto it.C) Because it is too expensive and aging.D) Because it is too complicated and always fails in function.2. Which of the following best describes the difficulty of taking super-sharp images from the ground?A) The climate changes from time to time so there is not enough sunshine.B) Stars blink from time to time so it is difficult to catch the sight of them.C) Warmer air or cooler air changes the function of the lens of the telescope.D) The atmosphere changes from time to time so the images of the objects in space are distorted. 3. How does the Lucky Camera work?A) It takes pictures with a detector in space and produces a combined one.B) It takes many pictures on the ground and produces a combined one.C) It takes many pictures of the space and selects the best ones. D) It takes pictures with a wide field of view and produces the largest one.4. Which of the following is true about the Lucky Camera?A) It is very efficient in taking supper-clear pictures.B) It has a wider field of view than the Hubble.C) It can see ultraviolet light.D) It takes sharper pictures than the Hubble could. 5. According to the passage, the Lucky Camera is a(n) ________ of the Hubble.A) competitorB) replacementC) backup choice D) improved version

53.根据下面资料，回答It is well that young men should begin at the beginning and occupy the most subordinate positions. Many of the leading businessmen of Pittsburgh had a serious responsibility thrust upon them at the very threshold of their career. They were introduced to the broom, and spent the first hours of their business lives sweeping out the office. I notice we have janitors and janitresses now in offices, and our young men unfortunately miss that salutary branch of business education. But if by chance the professional sweeper is absent any morning, the boy who has the genius of the future partner in him will not hesitate to try his hand at the broom. It does not hurt the newest comer to sweep out the office if necessary. I was one of those sweepers myself. Assuming that you have all obtained employment and are fairly started, my advice to you is "aim high". I would not give a fig for the young man who does not already see himself the partner or the head of an important firm. Do not rest content for a moment in your thoughts as head clerk, or foreman, or general manager in any concern, no matter how extensive. Say to yourself, "My place is at the top." Be king in your dreams. And here is the prime condition of success, the great secret: concentrate your energy, thought, and capital exclusively upon the business in which you are engaged. Having begun in one line, resolve to fight it out on that line, to lead in it, adopt every improvement, have the best machinery, and know the most about it. According to the author, to achieve his ambition, a young man should ____________. A.B. A. have the genius of being a future partner C.D. B. start at the grassroots and aim high E.F. C. work as a sweeper first to be a senior manager G.H. D. devote himself entirely to his work

Living in an urban area with green spaces has a long-lasting positive impact on people's mental wellbeing， a study has suggested． UK researchers found moving to a green space had a sustained positive effect， unlike pay rises or promotions， which only provided a short-term boost． Co-author Mathew White， from the University of Exeter， UK， explained that the study showed people living in greener urban areas were displaying fewer signs of depression or anxiety． "There could be a number of reasons，" he said， "for example， people do many things to make themselves happier： they strive for promotion or pay rises， or they get married． But the trouble with those things is that within six months to a year， people are back to their original baseline levels of well-being． So， these things are not sustainable； they don't make us happy in the long term． We found that for some lottery （彩票）winners who had won more than £ 500，000 the positive effect was definitely there， but after six months to a year， they were back to the baseline． " Dr． White said his team wanted to see whether living in greener urban areas had a lasting positive effect on people's sense of well-being or whether the effect also disappeared after a period of time． To do this， the team used data from the British Household Panel Survey compiled by the University of Essex． Explaining what the data revealed， he said： "What you see is that even after three years， mental health is still better， which is unlike many other things that we think will make us happy． " He observed that people living in green spaces were less stressed， and less stressed people made more sensible decisions and communicated better． With a growing body of evidence establishing a link between urban green spaces and a positive impact on human well-being， Dr． White said， There's growing interest among public policy officials， but the trouble is who funds it． What we really need at a policy level is to decide where the money will come from to help support good quality local green spaces．"（1）According to one study， what do green spaces do to people？ ____ A． Add to their sustained happiness．B． Improve their work efficiency．C． Help them build a positive attitude towards life．D． Lessen their concerns about material well-being．（2）What does Dr． White try to find out about living in a greener urban area？ ____ A． How it affects different people．B． How long its positive effect lasts．C． How strong its positive effect is．D． How it benefits people physically．（3）What did Dr． White's research reveal about people living in a green environment？ ____ A． Their stress was more apparent than real．B． Their decisions required less deliberation．C． Their memories were greatly strengthened．D． Their communication with others improved．（4）According to Dr． White， what should the government do to build more green spaces in cities？ ____ A． Find financial support．B． Improve urban planning．C． Involve local residents in the effort．D． Raise public awareness of the issue．
