He returned from his first visit to the place in late autumn, and could not get back until the snow melted in the following spring.Then he went to the pilot of a small plane, who earned his living by carrying hunters over parts of the country where there were no roads and no railways.He asked the pilot to take him back to the piece of forest.
The pilot did not know the place, so the hunter showed it to him on the map.“But there is nowhere to land there,” said the pilot.“I have flown over that we can’t land anywhere between this river and these mountains.”
“I thought you were a wonderful pilot,” said the hunter, “some of my friends said you could land a plane on a postage stamp.”
“That’s right,” answered the pilot.“I can land a plane where nobody else can.But I tell you there is nowhere to land in the place you are talking about.”
“And what if I tell you that another pilot did land me there last spring？” said the hunter.
“Is that true？” asked the pilot.
“Yes, it is.I swear it.”
Well, this pilot could not let himself beaten by another, so he agreed to take the hunter.
When they reached the place, the hunter pointed out a small spot without trees in the middle of the forest, with a steep rise(陡坡) at one end.The pilot thought there was not enough room to land there, but the hunter said that the other pilot had done so the year before, so down went the plane.When it came to the rise, it turned right over onto its back.As the hunter climbed out, he smiled happily and said, “Yes, that is exactly how the other pilot managed it last time.”.

Losing your ability to think and remember is prettyscary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia andage-related memory loss. After age 50, it's quite common to have trouble remembering the names of people, places andthings quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston. The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brainthat are important to learning, memory and planning. Changes in brain cells can affectcommunication between different regions of the brain. And blood flow can be reduced asblood vessels narrow. Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. Butif you forget the plot of the movie or don't remember even seeing it, that's far moreconcerning, Daffner says. When you forget entire experiences, he says, that's "a red flag that something more seriousmay be involved." Forgetting how to operate a familiar object like a microwave oven, orforgetting how to drive to the house of a friend you've visited many times before can also besigns of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can causeconfusion and memory loss, including health problems like temporary stoppage of breathingduring sleep, high blood pressure, or depression, as well as medications (药物) likeantidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to checkon medications, health problems and other issues that could be affecting memory. And the bestdefense against memory loss is to try to prevent it by building up your brain's cognitive (认知的) reserve, Daffner says. "Read books, go to movies, take on new hobbies or activities that force one to think in novelways," he says. In other words, keep your brain busy and working. And also get physicallyactive, because exercise is a known brain booster.Why does the author say that one needn't be concerned about memory slips？ 1..Why does the author say that one needn't be concerned about memory slips？()

B、They occur only among certain groups of people.
C、Not all of them are related to one's age.
D、They are quite common among fifty-year-olds.
截取一段明文如下:
The Mutual Information Analysis (MIA) is a generic side channel distingui she that has been introduced at CHES 2008. This paper brings three contributions with respect to its applicability to practice. First, we emphasize that the MIA principle can be seen as a toolbox in which different (more or less effective) statistical methods can be plugged in. Doing this, we introduce interesting altematives to the original proposal. Second, we discuss the contexts in which the MIA can lead to successful key recoveries with lower data complexity than classical attacks such as, eg. using Pearson's correlation coefficient. We show that such contexts exist in practically meaningful situations and analyze them statistically. Finally, we study the connections and differences between the MIA and a framework for the analysis of side- channel key recovery published at Eurocrypt 2009. We show that the MIA can be used to compare two leaking devices only if the discrete models used by an adversary to mount an attack perfectly correspond to the physical leakages.

me of medical science. Activists deny that we are trying to help and say it is () of our evil and cruel (). A more reasonable argument, however, can be advanced in our (). Life is often () to animals and human beings. Teenagers are flung from trucks and suffer severe head (). Young children () able to walk find themselves at the bottom of swimming pools while a parent is occupied with something else. From everyday germs to gang (), no life is free of pain. Physicians hoping to relieve the eternal suffering of these tragedies have only three choices: 1) create an animal model of the problem to understand the process and test new therapies; 2) experiment on human beings (some experiments will succeed, most will fail); or 3) leave medical knowledge static, hoping that () discoveries will lead us forward.
