Drying food is a simple, low-cost way to keep food safe for eating. Drying removes water that small organisms use to break down food into other substances. Some of these substances may be poisonous to humans.

A device that uses the sun is a good way to dry food. There are several kinds of solar dryers. The easiest to build is called the direct dryer. The sun shines directly on the food being dried. The direct dryer is a box with holes in it so that air can enter and leave the box. It has a cover made of clear glass or plastic. When the sun shines into the box, heat is produced. The heat is trapped inside the box and cannot escape back through the cover. The heat dries the food.

The solar dryer works better if the sides of the box are black. This is because dark colors hold heat while light colors reflect it. One way to make the sides black is to use wood that has been blackened by fire.

If you use black paint instead, be sure the paint contains no lead. Lead is poisonous to people, especially children.

The box can be made of almost any material such as wood, concrete or sheet metal. The dryer should be two meters long, one meter wide and twenty-three to thirty centimeters deep. The sides and bottom should have additional material, called insulation, to keep the heat from escaping.

The surface on which the food is placed should permit air to enter from below and pass through to the food. A surface made of wires with small square openings works very well. You should use wire with the largest openings or squares that do not allow the food to fall through. Air that comes in from below the wire surface will also carry away water evaporated from the food as it dries.

A direct dryer will dry most vegetables in two-and-one-half to four hours at temperatures from forty-three to sixty-three degrees Celsius. Fruits take longer, from four to six hours at the same temperatures.

51.Solar food drying is fast, safe and low-cost. It is also healthy because nutrients such as vitamin C are kept in the food. Solar dried food also tastes and looks good.

51.In which way will the food be fried quickly?

A.Let the sun shine directly on the food.

B.Make the sides of the box black.

C.Make wood be the sides of the box.

D.The box must be made of blackened wood.

52.What does the underlined word “evaporate” in the 6th paragraph mean?

A. sink into   B. change into gas or steam    C. flow away    D. flow into

53.According to the text., which of the following statements is true?

A.Water in the food may cause poisonous substances.

B.The sun shines into the box and be trapped.

C.Dark colours hold heat better than light colours.

D.It takes longer for vegetable to be fried.

54.What’s the text mainly about?

A.the way to dry food.

B.Solar Food Dryers

C.The device that uses the sun

D.The way to keep food safe.

Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the measure of progress without a proper appreciation of historical and cultural perspectives.
　　To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a mainly rural society with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient.
　　Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat loss and to reducing biodiversity.
　　All this means that agriculture in the 21st century will have to be very different from how it was in the 20th. This will require thorough thinking. For example, we need to move away from the idea that traditional practices are certainly more sustainable than new ones. We also need to abandon the notion that agriculture can be “zero impact”. The key will be to abandon the rather simple and static(稳定的)measures of sustainability, which centre on the need to maintain production without increasing damage. Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity.
　　What is important is recognizing that sustainable agriculture is not just about sustainable food production.
【小题1】How do people often measure progress in agriculture?

Artificial(假的) flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph.?

The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed. It contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use.?

Which of the following is the best title for the passage??

A. An Extensive Collection of Glass Flowers ?

B. The Lives of Leopold and Rudolph?

C. Flowers Native to the United States?

D. Material Used for Artificial Flowers?

It can be inferred from the passage that the goal of Leopold and Rudolph was to _______.?

A. create a botanical garden where only exotic flowers grew?

B. do a thorough study of plant structure?

C. make a copy of one member of each United States flower family?

D. show that glass are more realistic than wax flowers?

The underlined word “it” refers to _______.?

A. the intention　 B. the collection　　?

C. one member      D. each flower family?

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.

Lewis and his co-workers carried out their study by videotaping the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children." In general the more question-asking the parents do, the higher the children’s IQ scores," Lewis says. "And the more children there are, the less question-asking there is."

The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟，姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are that it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event(扫兴的事).”

Susan Sontag（1933—2004） was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything—to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s，publishing essays in such important magazines as Partisan Review，she appeared as the symbol of American culture life，trying hard to follow every new development in literature，film and art. With great effort and serious judgment，Sontag walked at the latest edges of world culture.
　　Seriousness was one of Sontag’s lifelong watchwords（格言），but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name，she explained what was then a little—known set of difficult understandings，through which she could not have been more famous.“Notes on Camp”，she wrote，represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’ ”.
By conviction（信念）she was a sensualist（感觉论者），but by nature she was a moralist（伦理学者），and in the works she published in the 1970s and 1980s，it was the latter side of her that came forward. In “Illness as Metaphor”—published in 1978，after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格），a concept that effectively blamed the victim for the disease. In fact，re-examining old positions was her lifelong habit.
In America，her story of a 19th century Polish actress who set up a perfect society in California，won the National Book Award in 2000. But it was as a tireless，all-purpose cultural view that she made her lasting fame.
“Sometimes,” she once said，“I feel that，in the end，all I am really defending…is the idea of seriousness，of true seriousness.”And in the end，she made us take it seriously too.
