Excerpt: ( from How Do Animals Move?)
Many animals scurry up tree trunks to escape enemies or find food. Some live in the treetops. Many of these animals are not only expert climbers, but they also have found interesting ways to get from tree to tree.
How Do Animals Adapt? and How Do Animals Move? are comprehensive explorations of animal adaptations and movement for young readers. Both are part of a 21 book series, The Science of Living Things.
In How Do Animals Adapt? readers learn how animals adapt to survive with respect not only to climate, darkness, food and defenses but also to offspring and people. These adaptations are well explained in double page spreads (跨报刊两版的文章) with examples clearly depicted (描绘) in photographs and diagrams and developed through their accompanying captions (图片文字说明).
As the title suggests, movement is the focus of How Do Animals Move? Beginning with a description of the explanation of movement, the reader is exposed to the many different ways of animals movement in the air, on land, under ground and in the water. Several unconventional (新奇的) variations (e.g. looping of inchworms, the rectilinear motion of snakes) are included. Once again, the photographs and diagrams plainly support the double page spread discussions of animal movement.
The language of both titles is simple enough for young readers without talking down to them. In both books, terminology (术语) is featured in bold. Some of these words are explained in the basic glossary(术语汇编)while the majority are explained clearly in the text. Many of these terms provide readers with some fascinating, uncommon words (e.g. brachiation, potassium, skein, and estimate). As do many of Kalman’s book, both of these titles have a table of contents, glossary and index (索引) which are all enough to introduce young readers to the nature of these tools.
Both titles would make excellent additions to any science collection for young readers.

This is a rabbit. It is running into its hole. You will say, “What has this to do with language?” Can you see the rabbit’s tail? When a rabbit sees something dangerous, it runs away. Its white tail moves up and down as it rurns and warns other rabbits that there is danger. The rabbit has told them something without making sound. It has given them a signal.
Many other animals use this kind of language. For example, when a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air.
____53____ A dog barks when a stranger comes near. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way by making sounds like “Oh!” or “Ah!” when we are frightened or pleased.
But we have something that no animal has a large number of words that have the meanings of things, actions, feeling or ideas. We are able to give each other information, to tell or inform other people what is in our mind or how we feel. ____54___ No animal has the wonderful power of language.
____55____ Perhaps he began by making sounds like those made by animals. Perhaps he made low rough sounds like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him --- water splashing(溅), bee humming(发出嗡嗡声), a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he made more and more new words. This is what we mean by language.
____56____ Today there are about fifteen hundred different languages in the world. Each contains many thousand words. A very large English dictionary, for example, contains four or five hundred thousand words. But we do not need all these. To read a book you need to know only about two thousand words. Before you leave school, you will learn only a few thousand more.

A. Some animals say things by making sounds.
B. No one knows how man learned to make words.

While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flower for a week or more without preservatives ( which contain biocides (杀虫剂) that kill bacterial and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water. 2. ( ) An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowered at the right temperatures is probably the most important aspect of flower care. 3. ( ) The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), supplies the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4. ( ) How, then, to control the speed at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature, we know that respiration produces heat, but the reverse (反面) is also true. Thus by keeping low temperatures, respiration is reduced and the cut flower will age more slowly. 5. ( ) Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach be added to each liter of water. The water and solution (溶液) should also be replaced each day. |
