Directions: There are five reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blackening the corresponding letter on the answer sheet.Passage OneArtificial 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 skill 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 artists-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 ate kept in locked cases, as they are too valuable and fragile for classroom use.31. Which of the following is the best title for the passage?A. An Extensive Collection of Glass Flowers.B. The Live Leopold and Rudolph Blaschka.C. Flowers Native to the United States.D. Materials Used for Artificial Flowers.

It can be inferred from the passage that the goal of Leopold and Rudolph Blaschka was to ______.A. create a botanical garden where only exotic flowers growB. do a thorough study of plant structureC. make a copy of one member of each United States flower familyD. show that glass flowers are more realistic than wax flowers

共用题干Keeping Cut Flowers(鲜切花)1. While everybody enjoys fresh cut flowers around his/her 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 lon-ger when kept at 12℃than when kept at 26℃.Keeping freshly harvested flowers at the right tem-peratures 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 at-tract 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 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 rate at which flowers die?By controlling respiration.How is respi-ration controlled?By controlling temperature .We know that respiration produces heat,but the re-verse(相反的过程)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(漂白剂)can be used in small quantities.It is recommended that 15 drops of chlorine bleach(at 4%solution)be add-ed to each litre of water. The water and solution should also be replaced each day. A few simple facts will help you keep cut flowers________.A: by keeping its original shape and colorB: in the life of cut flowersC: to produce carbon dioxideD: for as long as possibleE: by controlling temperatureF: to replace the water and solution every day
