题目列表(包括答案和解析)
History is full of cases where dreams have been a pathway to creativity and discovery. A striking example is provided by Dr. Otto Loewi, a pharmacologist and winner of a Nobel Prize. Loewi had spent years studying the chemical transmission of nerve impulses (脉搏). A tremendous breakthrough in his research came when he dreamed of an experiment three nights in a row. The first two nights he woke up and wrote down the experiment quickly and untidily on a pad. But the next morning, he couldn’t tell what the notes meant. On the third night, he got up after having the dream. This time, instead of making notes he went straight to his laboratory and performed the crucial experiment. Loewi later said that if the experiment had occurred to him while awake he would have rejected it.
Loewi’s experiment gives some insight into using dreams to produce creative solutions. Inhibitions (拘谨) are reduced during dreaming, which may be especially useful in solving problems that require a fresh point of view.
Being able to take advantage of dreams for problem solving is improved if you “set” yourself before retiring. Before you go to bed, try to think intently about a problem you wish to solve. Steep yourself in (潜心于) the problem by stating it clearly and reviewing all relevant information. Then use the suggestions listed in the previous section to catch your dreams. Although this method is not guaranteed to produce a novel solution or a new insight, it is certain to be an adventure. About half of a group of college students using the method for a week recalled a dream that helped them solve a personal problem.

A．very little is really known about the meaning of dreams
B．it is possible to “catch” one’s dreams by planning before going to sleep

C．comparing and exploring historical cases
D．telling in time order about one man’s research
3．If Loewi had thought of the experiment while awake, he would have .
A．asked someone else to do it B．thought it was a bad idea
C．tried it out on his own D．thought it was a wise idea
4．The author probably thinks that .
A．Loewi should not have conducted his experiment
B．dreaming is of very little value to most people
C．inhibitions may stop someone thinking of useful ideas
D．college students should not try out dream experiments
5．The author seems to be in favor of according to the passage.

Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知识库) which may be called experience, and the college students will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical (理论的) part -- the explanations of why things happen -- is frequently quite fantastic (神奇的) . But the demonstration (示范) and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he.
Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore (风俗). All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in this wide, confused wilderness and how often scientific discoveries of what had existed in this area long age.

Work your brain!
Between 2 and 3 pounds of wonder，it controls everything we say，do or think，who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein，fat, 100,000 miles of blood vessels and 100 billion nerve cells，it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its intricacies(复杂性)are stunning，far beyond anything most of us can imagine. To keep this work of art as polished(有光泽的) as possible we need to eat right，exercise and keep mentally stimulated(刺激)．
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone(荷尔蒙)in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It's very important that we tell people to be physically active and mentally active，” said neurologist Malcolm Stewart.
“People cannot stop aging，but you're able to reduce the damage；you're able to keep the function up.”
Following are Dr.Stewart's advice for improving brain health：
| Nutrition | Avoid fast food. Follow the old adage(格言，谚语)：For breakfast，eat like a king；for lunch，like a queen；for supper，like a beggar. |
| Exercise | Do a combination of stretching aerobic and musclestrengthening every day. |
| Mental games | Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. |
| A．inform us how the brain works |
| B．give us advice on how to keep the brain healthy |
| C．tell us that the brain plays an important role in our lives |
| D．show how special the brain is to us |
| A．interesting | B．strange | C．significant | D．amazing |
| A．keeps our mind sharp |
| B．helps improve our memory |
| C．gives our brain a rest |
| D．is good for brain cells communicating with each other |
| A．eating a good lunch | B．doing puzzles |
| C．eating a large supper | D．taking aerobic exercise |

In the college-admissions wars, we parents are the true fighters. We’re pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. I’ve twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids’ college background as a prize demonstrating how well we’ve raised them. But we can’t acknowledge that our obsession(痴迷) is more about us than them. So we’ve created various justifications（辩解）that turn out to be half-truths, prejudices or myths. It actually doesn’t matter much whether Aaron and Nicole go to Stanford.
We have a full-developed panic; we worry that there won’t be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. What causes the hysteria(歇斯底里) is the belief that scarce elite（精英）degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All seems right but mostly wrong. We haven’t found any convincing evidence that selectivity or prestige matters. Selective schools don’t systematically employ better instructional approaches than less selective schools. On two measures—professors’ feedback and the number of essay exams selective schools do slightly worse.
By some studies, selective schools do enhance（提高） their graduates’ lifetime earnings. The gain is reckoned at 2-4% for every 100-point increase in a school’s average SAT scores. But even this advantage is probably a statistical fluke(偶然). A well-known study examined students who got into highly selective schools and then went elsewhere. They earned just as much as graduates from higher-status schools.
Kids count more than their colleges. Getting into Yale may signify intelligence, talent and ambition. But it’s not the only indicator and, surprisingly, its significance is declining. The reason: so many similar people go elsewhere. Getting into college is not life’s only competition. In the next competition—the job market and graduate school—the results may change. Princeton economist Alan Krueger studied admissions to one top Ph.D. program. High scores on the GRE helped explain who got in; degrees of famous universities didn’t.
So, parents, take it easy（lighten up）. The stakes (利害关系) have been vastly exaggerated. Up to a point, we can rationalize our pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be destructive. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction. They may have been so conditioned to being on top that anything less disappoints.
