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.

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

A.Water in the food may cause poisonous substances.

People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues（线索）that will help them or someone else to find it again.

In Britain a few years ago, a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.

One of the most popular adventure stories ever written is Robert Louis Stephenson's “Treasured Island”, an exciting story about a young boy, Jim Hawkins, who is captured by pirates (海盗) and later finds some buried treasure.

Then there is the true story about a man who had to travel overseas for a year. He did not trust banks, so he buried his life savings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.

And then there was the man who buried his savings, all in bank notes, in a waterproof（防水的）bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.

And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.

以下是一些新闻报道的信息：

[A]. Science magazine published the study about orangutans. The scientists collected evidence from years of observations in six areas on Borneo and Sumatra. The scientists found that the animals demonstrated a total of twenty-four signs of cultural activity. Several actions were demonstrated in some orangutan groups, but not others.

[B]. The Environmental Investigation Agency and Telapak released the report. Telapak is an environmental group based in Indonesia. The Environmental Investigation Agency operates in several countries. The two groups say Indonesia controls ten percent of the world's tropical rainforests.

[C]. Richard Sandor is the chairman of the C-C-X. He praised the companies forming the group for demonstrating leadership. He said they believe that an active way to deal with global warming helps everyone. The group said its members want to reduce costs they may face from future rules on greenhouse gas emissions. Trading credits may help businesses find the most effective methods to reduce pollution. Members also hope to improve their public image on environmental issues.

[D]. Their most detailed effort involved ninety-nine kinds of birds, insects and plants in North America and Europe. They found that the territory where these plants and animals live has moved north by an average of six kilometers every ten years. In Europe, some butterflies now live as much as one hundred kilometers to the north because of changes linked to higher temperatures.

[E]. The new report says many areas experienced unusual weather in two thousand and two. Most of Asia, for example, was warmer than usual. India had unusually high temperatures in April and May. The extremely hot weather caused hundreds of deaths. There also were extremely dry conditions across India. Parts of Africa experienced unusual heavy rains. Yet other areas in Africa had unusual dry weather.

[F]. Hydrogen is the most common element in the universe. Hydrogen is a colorless gas. On Earth, it is present in large amounts in natural gas, coal, plants and water. By weight, hydrogen produces the highest energy levels of any known fuel. When burned in an engine, hydrogen releases no harmful pollution into the environment. When powering a fuel cell, the only waste is water. However, hydrogen is difficult to store. It also burns easily.

The scientists found that some of the animals use sticks as tools to remove insects from holes in trees. Other orangutans use leaves to crush insects or gather water.

59. Professors Parmesan and Yohe used similar methods to examine one hundred and seventy-two kinds of wildlife.
