Not only is it useful in making these foods, but it is also beneficial to the consumer because of its high protein content. Gelatin is also commonly used in the photographic industry and in making medicinal capsules The process for producing gelatin is a long and complex one. In the processing of gelatin made from bones, which varies slightly from that of gelatin made from skin, the grease first must be eliminated. Then, the bones are soaked in a solution of hydrochloric acid in order to rid them of minerals and are washed several times in water. Next, the bones are placed in distilled water, heated to over 90"F for a few hours, placed in fresh distilled water, and then heated again at a little over 100F.

第 9 页 共 11 页 Passage 2 Questions 7 through 10 are based on the following reading. Gelatin is a protein substance that comes from the skins and bones of animals. Most people know it as the substance used to make a jellylike salad or dessert. Not only is it useful in making these foods, but it is also beneficial to the consumer because of its high protein content. Gelatin is also commonly used in the photographic industry and in making medicinal capsules. The process for producing gelatin is a long and complex one. In the processing of gelatin made from bones, which varies slightly from that of gelatin made from skin, the grease first must be eliminated. Then, the bones are soaked in a solution of hydrochloric acid in order to rid them of minerals and are washed several times in water. Next, the bones are placed in distilled water, heated to over 90ºF for a few hours, placed in fresh distilled water, and then heated again at a little over lOOºF. A fluid forms from this heating, and it is concentrated, chilled, and sliced. Finally, it is dried and ground. In its anal form, gelatin is white, tasteless, and odorless. 7.What can we assume from this reading passage? . 9. Gelatin made from skin is produced in the same way as that made from bones. Is this statement true? Why? 9.What do you think would be the best title for this passage? 10.Which of the following industries is not mentioned as using gelatin? (A)lawn care (C)pharmaceutical (B)photographic (D)food Passage 3 Questions 11 through 15 are based on the following reading. In recent Years, scientific and technological developments have drastically changed human life on our planet, as we11 as our views both of ourselves as individuals in society and of the universe as a whole. Maybe one of the most profound developments of the last decade-is the discovery of recombinant DNA technology, which allows scientists to introduce genetic material (or genes) from one organism into
another. In its simplest form, the technology requires the isolation of a piece of DNA, either directly from the dna of the organism under study, or artificially synthesized from an rna template by using a viral enzyme called reverse transcriptase. This piece of DNA is then ligated to a fragment of bacterial DNa which has the capacity to replicate itself independently. The recombinant molecule thus roduced can be introduced into the common intestinal bacterium escherishchia coli. which can be grown in very large amounts in synthetic media. Under proper conditions, the foreign gene will not only replicate in the bacteria, but also express itself, through the process of transcription and translation, give rise to large amounts of the specific protein coded by the foreign gene The technology has already been successfully applied to the production of several therapeutically important biomolecules, such as insulin, interferon, and growth hormones. Many other important pplications are under detailed investigation in laboratories throughout the world 11. Recombiant DNA technology consists primarily of (A)producing several therapeutically important biomolecules B)giving rise to large amounts of protein (C)introducing genetic material from one organism into another (D)using a viral enzyme called reverse transcriptase 12. Recombinant DNa technology has been used in the production of all of the following biomolecules (A)growth hormones (C)interferon B)Escherishchia coli (D)insulin 13. Which of the following is not true? (A)The foreign gene will replicate in the bacteria, but it will not express itself through transcription and translation (B)The bacterium Escherischia coli can be grown in large amounts in synthetic media. C)Research continues in an effort to find other uses for this technology (D)Recombinant DNA technology is a recent development 14. Expression of a gene in Escherischia coli require (A)the viral enzyme reverse transcriptase ( B)the process of transcription and translation (C)production of insulin and other biomolecules (D)that the bacteria be grown in a synthetic media 15.
