【正文】 There are many reasons for changing plants in this way. International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher yielding(高產(chǎn)的), disease resistant, drought tolerant or regionally adapted to different environments and growing conditions. For example, some genetically engineered plants can live through frost or draught. As a result, famers can make more profit because fewer plants will die. Actually, plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers and by professional plant breeders employed by organizations such as government institutions, universities, cropspecific industry associations or research centers. They have crossbred plants to create the new types of plants that are, for example, bigger, stronger, or more attractive.8．閱讀理解 Benefits and Problems of Genetic Engineering 【點(diǎn)評(píng)】查閱讀理解。根據(jù)本文最后一句And the impact is huge. 可知大聲閱讀對(duì)孩子們未來的發(fā)展影響很大。故D項(xiàng)正確。 （4）推理判斷題。s have a holiday for the read aloud可知小男孩的主意是出去度假來宣傳read loudly的好處。根據(jù)第四段第一句What he said was this: Mrs. Allyn, let39。故B項(xiàng)正確。根據(jù)第三段第一句Years later, I was reading aloud a picture book to a small child in a classroom. 可知作者是在教室里向一個(gè)小孩大聲朗讀一本圖畫書。故A項(xiàng)正確。根據(jù)第一段最后兩句I remember as if it were yesterday, hearing her voice at my side on a cold wintry night.

A.Imitating a developing technique.C.Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said The challenge will lie in persuading the relevant authorities to sponsor these tasks. Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.（1）What is the use of the RemoveDEBRIS satellite? A. s experiment was exciting, but he cautioned against over publicizing it. Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.s Surrey Space Center and includes Airbus, Airbusowned Surrey Satellite Technology Ltd. and France39。 Various panies have plans to send thousands of new satellites into lowEarth orbit, already the most crowded area. The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space. 6．閱讀理解 可知選C。 （3）考查細(xì)節(jié)理解。 出于好奇心，他們做了一系列實(shí)驗(yàn)。 needs and drive cooperative behavior as a result.
