It had been a pleasantly warm day, without much wind, and enough cloud to prevent the heat of the sun becoming too great．Charles had spent a long time studying the level of the water in the boat, and had discovered that, by evening, it had fallen very slightly．This, it would seem, must mean that the boat was not taking in water which was fortunate, because any attempt to empty it out suggested greater effort than he felt equal to．One other immediate problem had held his wandering thoughts for a few moments at long intervals．This was the problem of his friend Harcourt．The thing to do, Charles realized, was to put poor Harcourt in the sea, It should be a simple matter and take no more than a few seconds．Charles arranged in his mind exactly how it could most easily be done, but his body did not react to the suggestions of his mind．Charles thought his hands might be too badly burnt to use．But then, suddenly, almost without knowing how he did it, Charles moved, stood up, bent over the body of poor Harcourt, lifted it and let it slip as gently as possible into the sea．Afterwards he stood in the stern of the boat for a long time, watching the color of the sea deepen and the sky become increasingly farther off with the coming of night．In a curious way he felt strangely happy．The problem of his rescue had not yet begun to trouble him.

    After a time Charles’s returning interest in living showed itself in the simple form of hunger．With some difficulty, owing to the water in the boat, he explored its stores and found food and water in airtight tins．He also found a neat package wrapped in green oiled silk．He unwrapped it and found maps．Neat, beautifully designed and printed, spotlessly new, they lay across his knees and he was no longer alone in a world of water．At that moment these clean official maps were as comforting as the sound of a human voice, as cheering as a candle in darkness.

“Get up, you lazy-bones!” Still rubbing his sleepy eyes, Li Ming had to rise．“I worked till far into the night,” he murmured, half to himself, “Daddy, I was dreaming a strange dream．I was an emperor...”

    “A pupil, who always can’t finish his homework, wants to be an emperor?”

    “Why not? The Minister of Education was just in front of me．I ordered him to give those whose parents are teachers many exercises, much homework! Nonsense! (废话)” shouted the man impatiently．“Have breakfast, then go on with your lessons!” “But it is Sunday, Daddy．”

Modern technology has developed in a manner which often conflicts with the environment．Nevertheless, it is possible and practical to achieve a high level of technology without altering the overall natural environment.

    There are two basic methods of conserving(保护) the natural environment．One is alternative technology in which techniques (such as windmills and solar energy) must be found for providing power．The other is to try to minimize the effects of modern technology by the more efficient use of materials and more effective pollution control．There comes a point when the quality of life can no longer be improved because of the high population density(密度) and the largely unsuccessful at tempts to meet its demands.

    Present energy policies of the western world are considering new energy sources to meet the demands of a growing population．The main sources used have been oil, gas, and coal- which are in limited supply- and nuclear power, which has problems concerning radioactive waste storage．Wind and solar energy are alternative possibilities, but only solar energy is likely to become a main power source for many countries.

    Many of the materials used daily in a technological society are destined(注定) to be discarded, Rags, paper, metal, glass, and plastics are all substances that could be recycled or reused．Research is being done to determine methods of separating useful products from industrial and domestic waste.

    The processing of sewage requires considerable amounts of electricity．Many sewage treatment plants in the U.S．have become self-sufficient by using the methane gas(沼气) given off by sewage．This is collected in gas holders and burned to produce heat and create electricity．The solid waste itself is often used for soil enrichment.

1．Modern technology is harmful to the natural environment because ________

A．of industrial pollutants.

B．it has become too expensive.

C．it has become too complicated.

D．it consumes all natural resources.

2．Alternative technology suggests that ________

A．new ways be found to burn coal, oil and gas.

B．solar energy and wind power be considered.

C．new ways be found to store radioactive waste.

D．the present energy resources be fully used.

3．Methane gas in used to ________

A．conserve(保存) industrial residues (废料).

B．create recycled paper products.

C．provide electricity to process sewage.

D．treat with the raw sewage.

4．From the selection, we can determine that ________

A．conservation technology is a necessity.

B．nuclear power is the energy source of the future.

C．problems of energy conservation are not worldwide.

D．all the industrial and domestic wastes can be reused and recycled.

5．Processing sewage requires large quantities of ________

A．water.

B．electricity.

C．gas.

D．oil.

Where you do your food shopping often affects your grocery bill．It’s best to check the prices in nearby stores for the foods you buy all the time．You can then decide which store gives you the best prices．Check, too, for other features that may be useful to you．Which store offers the freshest foods? Which store has off-street parking and will cash your checks?

    Small stores often will deliver orders to your home．If you do not need this service, you will do better shopping at a large chain(连锁店)．The large chain markets offer more varieties and have better prices.

    For most people it is best to choose a store with good prices and stay with it．Store-hopping(逛街) for sales on certain foods may save you pennies, but it can be costly in time and gas.

    The meat, poultry(禽), and fish items in your menu usually cost the most．Studies show that one-third of the money spent on food goes for these items．To take advantage of the best buys at the meat counter, you need to be aware of the many cuts(切块) of meat that are available．Also, you must know how to use them in meals．Keep in mind that the economy of a cut depends on the amount of cooked lean meat it serves as well as its price per pound．Often the cut with a low price per pound is not the best buy．What counts (有价值) is the amount of lean meat and the number of servings(一份菜) it will provide．For example, a high-priced meat with little or no waste may be a better buy than a low-priced cut with a great deal of bone or fat．So when you visit the market, be a smart shopper and take time to make the right choice.

1．For foods you buy all the time, it is good to check different stores to find ________.

A．the freshest foods.

    For hundreds of years the madder plant was our only source of yellow dye. The dye was extracted from the roots of the plant and sold all over the world．The great plantations in Southern France were devoted to the cultivation of the madder plant until 1869．In that year German scientists discovered that the dye could be produced artificially. A chemical that was extracted from coal tar was their answer. Alizarin, as it is called, was cheaper to produce, easier to use and more permanent (永久的) in coloring. The dyers of cloth turned to this new product, and the madder growers of France had to look for new crops to cultivate.

1．Our only source in formers times for yellow dye was ________.

A．chemicals

B．coal tar

C．plant

D．German plantations

2．The chemists discovered ________.

A．a better dye

B．coal tar

C．the madder plant

D．yellow dye

    The cold is the most common of man’s ailments(疾病). Yet it stumped(难住)the medical authorities. Many of more terrible diseases have come under the control of modem man as the result of the knowledge gained in the lab of science research. Investigators have thought that the cold is usually caused by a virus(病毒). However, no method of studying this virus has been devised(提出). The chimpanzee(黑猩猩)is the only animal to which the disease can be given experimentally. The use of this animal is limited by its cost and by the fact that so many of the animals die of pneumonia during the experiments. This leaves for all practical purposes only human volunteers to be used in research projects. Many people of prisons have helped in this work, but because of .these limitations, research into the cause and cure of colds has progressed very slowly.

Research into the cause and cure of colds has________.

A．gone ahead very slowly

B．gone ahead very quickly

C．been very common

D．been impossible

As a result of his twelve victories over the invading Saxons, Arthur brought a 24- year period of peace to his people. In 542 his nephew Modred led an unsuccessful revolt against Arthur. Arthur defeated Modred but was mortally wounded in the battle.

The best title is ________.

A．The Silures

B．The Pendragon

　　  Some people believe that they can study just as well or even better when the music - makers are turned on. Experiments among workers, however, have proved that they work better when there is no noise. They get their work done quicker and better when the place is quiet. Actually, the student who studies to the tunes of the hi-fi set has to waste part of his energy ignoring the tape deck or radio. If he does not fight the sounds, then, while he is listening, he is an inefficient studier. Noise, even good music, uses up some of the energy that is needed for concentration. The facts seem to show that it is not true that people can study better with music in the air.

A suitable title for this passage is  ________.

A．Radio music and study

B．Experimentation

C．Noise

D．Music
