第1题:这里有一个控制农业杂草的新办法,它不是试图合成那种能杀死特殊野草而对谷物无害的除草剂,而是使用对所有植物都有效的除草剂,同时运用特别的基因工程来使谷物对除草剂具有免疫力。 下面哪个,如果正确,是以上提出的新办法实施的最严重障碍
A.对某些特定种类杂草有效的除草剂,施用后两年内会阻碍某些作物的生长。 B.最新研究表明,进行基因重组并非想象的那样可以使农作物中的营养成分有所提高。 C.大部分的只能除掉少数特定杂草的除草剂含有的有效成分对家禽、家畜及野生动物有害。 D.这种万能除草剂已经上市,但它的万能作用使得人们认为它不适合作为农业控制杂草的方法。 E.虽然基因重组已使单个的谷物植株免受万能除草剂的影响,但这些作物产出的种子却由于万能除草剂的影响而不发芽。 |

第3题:The invention of both labor-saving tools and tools of intelligence is rarely accidental. Instead, it is usually the product of human need; (21) is truly the mother of invention. People usually devise tools to (22) for natural deficiencies. For example, people invented weapons to defend (23) from physically superior (24) .But (25) is only one incentive for inventions. People also invent (26) tools to (27) certain established tasks more efficiently. For instance, people developed the bow and arrow from the (28) spear or javelin in order to shoot (29) and strike with greater strength. (30) civilizations developed, greater work efficiency came to be demanded, and (31) tools became more (32) .A、tool would (33) a function until it proved (34) in meeting human needs, at which point an improvement would be made. One impetus for invention has always been the (35) for speed and high-quality results--provided they are achieved (36) reasonable costs. Stone pebbles were sufficient to account for small quantities of possessions, (37) they were not efficient enough for performing sophisticated mathematics. However, beads arranged systematically evolved into the abacus. The (38) of this tool can be (39) to the development of commerce in theEast around 3000B、C、, and the abacus is known (40) by the ancientBabylonians,Egyptians,Chinese, etC、 A、substituteB、compensateC、accountD、qualify |

第4题:一份最近的研究报告表明,尽管只有3%在京石高速公路上驾驶的司机为其汽车装备了雷达探测器,但是在因超速而被罚的所有汽车中,却有33%以上的汽车装备了雷达探测器。显然,车上装备雷达探测器的司机比没有装备雷达探测器的司机更有可能经常超速。 以下哪项最可能是上述论证所必须假设的 A、因超速而被罚的司机比超速但没有被罚的司机更有可能经常超速。 B、车上装备雷达探测器的司机比没有装备雷达探测器的司机因超速而被罚的可能性更小。 C、因超速而被罚的汽车数量多于装备雷达探测器的汽车数量。 D、在该报告涉及的时期内,许多因超速而被罚的汽车不止一次被开过罚单。 E、在京石高速路上驾驶的司机比在这份报告中没涉及到的其他高速公路上驾驶的司机更经常超速。 |
