第二篇Teaching poetry No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it. All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling "interpretation" of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting(背诵) it. I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn’t time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is " a criticism of life", and " a heightening(提升) of life". It is "an approach to the truth of feeling", and it " can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies. I am not saying that every English teacher must teach poetry. Those who don’t like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few thing s about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it. Which of the following is NOT mentioned as a function of poetry（）

Keeping Cut Flowers 1.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.2.An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12oC than when kept at 260c. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.3.Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide (二氧化碳), called respiration (呼吸), generates the energy the flower needs to give the flower its shape and colour. 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 rate at which flowers die By controlling respiration. How is respiration controlled By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining 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, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water. The water and solution should also be replaced each day. Paragraph 4（）
