1、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them fｏｒas long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Fｏｒexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. 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 ｏｒinsects, such as bees, fｏｒpollination (粉). After that, they quickly dry up ａｎｄ　die. The process by which flowers consume oxygen ａｎｄ　produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape ａｎｄ　color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, ａｎｄ　fｏｒflowers 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 factｏｒin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty ｏｒotherwise 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 liter of water. The water ａｎｄ　solution should also be replaced each day. Respiration plays a key role____. 【单选题】

A.by keeping its original shape ａｎｄ　color

B.in the life ofthe cut flower

C.to produce carbon dioxide

D.fｏｒas long as possible

E.by controlling temperature

F.to replace the water ａｎｄ　solution every day

正确答案:B

答案解析:本题其实与上面第24题意思相似，都是在说呼吸的作用。通过对第24题的分析我们知道呼吸在花朵一生中起到了重要作用，选项B符合题意，故选B。

答案解析:本题的题设具有迷惑性，选项A和选项F都与“花朵的呼吸”有关，但是选项1是说如何控制呼吸，而选项F是说如何停止呼吸。回到原文，我们发现作者并没有提到停止呼吸，只是说要通过降低温度来控制呼吸，故选1。

4、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. The VLT will allow scientists to see events____. 【单选题】

A.its detecting power

B.millions of light years away in space

C.the location of the VLT

D.as an example

E.the birth of the earth

F.the rotation of the earth

正确答案:B

答案解析:文章第2段最后一句提到了这句话的意思。
