the rush of energy as waves came over you."?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.
Scientists are working to use that energy to make electricity. Most waves are created when winds blow
across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those
ripples get bigger and bigger and turn into waves," Taylor said."Waves are one of nature"s ways of picking up
energy and then sending it off on a journey."
When waves come toward the shore, people can set up darns to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.
"The resource is huge," said Janet Swain of the Worldwatch Institute. "We will never run out of wave
power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal.
Oceans cover three-quarters of the Earth"s surface-that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still
unknown. What is more, wave power could affect fishing and boat traffic.
Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs
and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

B. speeding up
C. gathering
D. improving
B. build more small power stations on the oceans
C. reduce the cost of turning it into electric power

grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one metre
apart. The plant is often pruned so that it remains only 60 to 90 centimetres high. Pruning is important
because it encourages the growth of tender shoots, or young leaves. It is from these shoots that the best tea
is got.
Practically all the tea pickers are women. The estates prefer to employ women pickers because they are
more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are
the parts used for processing (加工) tea. The pickers carry large baskets into which they throw their pickings.
A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be
picked from the plants about every ten or fifteen days.
Processing tea shoots into the familiar dry tea leaves requires great care and skill. There are various
methods of processing depending on the type of tea required.For black tea,the young green leaves are first
spread out shelves to dry. This process removes much of its water and the leaves become soft. After this, the
leaves are passed through heavy rollers.This operation will press the leaves for juices which give the tea both
its colour and taste.Then the leaves are spread out on floors and left to ferment (发酵) under wet conditions.
Fermentation develops the rich taste of black tea.The fermented leaves are then dried with a hot-air blower
until they become rolled-up black leaves.The final step is to sort and grade them before the black tea is ready
for sale to countries all over the world.
B. frequent watering
C. regular use of chemicals
D. growing the plants high in the mountain
B. they can throw their pickings more easily into the baskets
C. their fingers fit them better for the job.
D. they can more easily find the twin leaves.
B. Four.
C. Five.
D. Six.
B. To persuade readers to buy tea from Sri Lanka.
C. To tell a story that had happened in the tea gardens.
D. To inform readers of tea growing, picking and processing.
A supporter of co-educational schools would probably say that schools should be like the societies they
belong to. In Hong Kong, men and women mix socially on a day-to-day basis. In many fields men are even
likely to have female bosses. It is, therefore, desirable that boys and girls grow up together,go to school
together, and prepare themselves for a society that does not value sexual separation.
Some would go on to argue further that growing up with members of the opposite sex is important for
personal development. Regular contact (接触) can remove the strange ideas about the opposite-sex and lead
to more natural relationships. Single-sex conditions are seen as leading to more extreme opinions, and possibly
even as encouraging homosexuality (同性恋), though there is no proof that this is the case.
Those who are against coeducation often also fix their attention on the sexual side. Some parents fear that
close contact with members of the opposite sex is dangerous for teenagers. They want their children to be
attentive to their studies. Such parents feel uncomfortable with modern ways and the free mixing of the sexes.
A stronger argument comes from research into school results. Girls grow up earlier than boys, tend to be
more orderly and are likely to be better at languages. In a mixed class,boys who might do well in a single-sex
class become discouraged and take on the rule of troublemaker. Certainly in the UK this situation has greatly
alarmed (惊动) the government for it to be encouraging co-educational schools to have some single-sex
classes. In the UK the best schools are all single-sex, strongly suggesting that co-education is not the best
answer. This may, however, not be as simple as it looks.It may simply be that the famous old schools that
attract the best students happen to be single-sex, rather than that being single-sex makes them better schools.
means that _____.
B. students in co-educational schools cannot have extreme opinions
C. students in co-educational schools are likely to be homosexual
D. single-sex school conditions may or may not have effects on the students.
B. co-educational schools may lead to love affairs between boys and girls
C. co-education will help develop a better understanding about the opposite sex
D. co-education can make boys perform well in mixed classes
B. single-sex education
C. single-sex classes in co-educational schools
D. co-educational classes in single-sex schools
B. being single-sex does not necessarily make a school better
C. co-educational schools are better for both sexes in personal development
D. because boys cannot compete with girls in study,they go to single-sex schools
Imagine Children"s Literature Festival last autumn. Each child (aged 12-13) beatified a box and wrote a story
on the subject of collections to throw inside it. The boxes were spread within the Royal Festival Hall"s
Ballroom. Some were left empty to encourage
The subject chosen by Luren was an imaginative one. "It"s a sort o f Cinderella (灰姑娘) story," she told
me, inspired by a collection of letters from her cousin, ha the story these become love letters, burned by a
creel stepmother. Lauren"s best friend Charlotte is the stepmother. "I"m in Charlotte"s story too," says Lauren,
"and I get run over." Charlotte"s tale was inspired by the girls" coin collection."We"ve collected foreign coins
for years-since our families went on holiday to Tenerife." she explains."That was before the Euro, so we put
pesetas in." Lauren continues: "I fred a coin in the road, go to get it and get run over. I"m in hospital and then
I die." Charlotte adds: "Or she might not die. I haven"t decided yet."
Millie Murray, who is a tea-novel author, thinks that setting the subject of collections was a useful
inspiration to their creativity rather than a restriction (限制). "In the beginning I thought, "Will the children be
able to do it?"" she says. "But it"s been fruitful. Some have their own collection, some have parents who do,
and some have wlstten complete stories. It"s made them think about something they wouldn"t have otherwise,
winch can only be a good thing."
B. To write stories on the subject of collections.
C. To encourage visitors to write their own stories.
D. To have their friends for characters in the stories.
B. collection
C. inspiration
D. foreign coin
B. both of them developed their imagination
C. both of tram will die in each other"s stories
D. Latwen"s cousin posted her some love letters
B. it was good for parents to have collections
C. inspirations were very useful in writing stories
D. setting collection subjects restricted inspirations
week, contained mindless memorization of big words like "batholith" and "saprophyte" She learned by heart the
achievements of famous scientists who did things like "improved nuclear fu-sion (核聚变)"-never mind that
she hasn"t the least idea of what nuclear fusion means. Eliza-beth did very well (she"s good at memorizing things ). And now she hates science. My eighth-grad-er son,Ben,also suffered from science education. Week after
week he had to perform lab experiments with answers already known.Ben figured out how to guess the right
answers, so he got good grades. Now he hates science, too.
Science can provide an exciting way to develop children"s curiosity. Science education should teach ways
to ask questions and week answers. But my children got the mistaken idea in school than science is difficult
dull and has no relation to their everyday interests.
As a physicist, I am saddened and angered to see "the great science turnoff" I know that science is
important in our lives.Yet studies prove that our schools are turning out millions of graduates who know
almost nothing about and have almost no interest in science. What"s gone wrong? Who is to blame?
B. both Elizabeth and Ben could become scientists
C. Elizabeth had to learn much about great scientists
D. Ben was good at trying new ideas in lab experiments
B. answer students" questions in delightful ways.
C. smooth out difficulties in lab experiments
D. explain the special terms clearly
B. the way science is taught in school
C. the achievements of famous scientists
D. students" poor records in science classes
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
