题目内容
laws of motion, Kepler's principles of planetary movement, Einstein's general theory of relativity. Equally
awe-inspiring are artistic creations in painting, theatre, music, and literature, which have also been brought
about by discovery through personal efforts. What do these extraordinary achievements of well-known
scientists and artists have to do with problem solving?
A great scientific discovery or a great work of art is surely the result of problem-solving activity. The
solution to a problem, we are told, often comes to thinkers in a "flash of insight (顿悟)", although they may
have been turning the problem over in their minds for some time. As a particular form of problem solving,
these creative acts are based on the broad knowledge gained in the past, whether this be of the " public" sort
known to science, or of the "private" sort known to the artist.
Many creative thinkers state that they have completely devoted themselves to the subject matter of the
problem, often over fairly long periods of time. Indeed, it would be strange if they had not done this.
Nothing in such statements supports the idea that there is anything very different about the problem solving
that leads to discoveries of the great contributions to the society. The act of discovery, even in the relatively
predictable (可以预见的) sense that it occurs in everyday learning, involves (涉及) a " sudden insight"
which changes the problem situation into a solution situation. As we have seen, everyday discovery also
0requires that the learner have the knowledge of the rules gained in the past, which is involved in the solution.
B. explain that scientists are more creative
C. show the difference between science and arts
D. prove that arts require more personal efforts
sometimes also depend on their _____.
B. sudden insight
C. admiration of discoveries
D. scientific experiments
B. Long-time study of the subject matter.
C. Various statements about problem solving.
D. Complete devotion to artistic creation.
B. a sudden insight and knowledge from the past are required in making discoveries
C. scientific discoveries or artistic creations are usually unpredictable in nature
D. knowledge of the rules in the past is often developed in the changes of situation

Write NO MORE THAN THREE WORDS for each answer. With an obese (very fat) or overweight population of 66% percent of adults, teaching your kids healthy eating habits is one of the most important things you can do for them as a parent. Most parents and children claim that breakfast is part of their everyday routines. But for many more than you might think, it's not. Children who eat breakfast have higher math grades, have improved reading scores and basically perform better in school. They also tend to have healthier bodies in general, with better-controlled weight levels. When you take them to the grocery store with you, it's doubtless that your children will request the most sugar-filled, fat-injected products on the shelf. But these are not the ones to have in your home-you should avoid buying them at all. Be sure your kids have healthy snacks. Yes, kids like white bread. But any kid can get used to the taste of whole grains. It just takes a little practice. Look for white bread, and add other whole grains into their diet. Start toasting their sandwiches. When it's toasted, it'll be that much harder for them to tell the difference in taste. It's simple, it's true, and it's something you already know: kids who get plenty of exercise are healthier kids. Set limits on the amount of time your child may spend in front of the television or computer screen. Sign them up for plenty of sports and outdoor activities. And best of all, get involved in sports and exercise with them. One of the best things you can do to establish healthy eating habits in your kids is to have them yourself. You can tell your kids every day to eat healthy foods, but if you don't do the same thing yourself, the lesson will never stick.

Write NO MORE THAN THREE WORDS for each answer. Tomatoes are the world's most popular fruit rich in nutrition like Vitamin A, C, fibre and lycopene (番茄红素). Researchers have found that consuming lycopene helps in preventing cancer. Tomato also helps in keeping the skin healthy and young by protecting from harmful rays. Since lycopene is present in the cellular wall of tomato, it is better to consume cooked tomato to have higher concentration of lycopene. So tomatoes are a wonderful fruit. Then how to grow tomatoes? First, there should be regular and even watering in the fields where tomatoes grow. You can also add fertilizer to have better results. Plant the tomato plants with enough space(for example 2 to 3 inch space)between each other to lessen spreading of disease and pests and help the fruits get enough sunlight. Provide support like pole when the plants grow up to prevent from disease and to increase the crop product. In order to make your tomatoes grow well, you should take some useful tips. For example, choose variety based on the season and soil type that you are growing. Planting site should have enough sunlight to have more fruits. Prune(修剪)the tomato plants if necessary to maintain a manageable size. Check tomato plants regularly for any kind of pests and diseases. To people's regret, tomatoes possibly suffer from some diseases during their growth. So you must try your best to prevent them. Soil should be free from debris(残骸)of earlier plant remains and should be treated first before tomato plantation like solarizing(晒) to prevent from pests. It is always better to choose resistant plant varieties and follow crop rotation(轮作)as far as possible.
