Many plants in nature actually clone themselves and reproduce asexually (无性生殖地)3Cloned plants are much more predictable than normal plants, so their yield (产量) is more reliable. Cloned plant

11、s also reproduce faster, limiting the amount of time between planting and harvesting. It is also often cheaper to produce seeds through cloning than through traditional methods. Plants can essentially be optimized so that farmers or individual growers always have the best seeds available. With highe

12、r yield at a faster rate, farms can produce more food for more people while decreasing overall costs.Cloning can be used to wipe out diseases that previously killed off entire fields of crops. This would make plants immune to the kinds of diseases that farmers and gardeners around the world fear eac

13、h year. Crop failures due to disease and virus could become a thing of the past. Also, plants that are near extinction can be brought back to life through cloning.Through cloning scientists can develop super fruits and vegetables of superior (更好的 ) nutritional quality. This could make for a healthie

14、r population overall. This has already been done through selective pollination (授粉), and genetic cloning could take it to the next level.By plant cloning we have a population of identical plants and all these plants equally suffer from the same diseases, but in nature the weak would die and the stro

15、ng would survive. While there are some dangers to consider with plant cloning, there are plenty of benefits that could prove vital to the propagation (繁衍) of the human species.语 篇 解 读 ： 本 文 是 说 明 文 。 文 章 主 要 介 绍 了 植 物 克 隆 的 好 处 。5The underlined word “optimized” in Paragraph 2 is closest in meaning 4

Many

21、planes, ships, and boats are said to have disappeared in this triangle without a trace, which led to the belief that “supernatural” forces exist in this area of the sea.Could there truly be an unnatural force at work in this geographical triangle or are these disappearances merely coincidence?

23、6th century AD. Over the years thousands have reported seeing a long neck appearing from the water with a small head of an unknown creature.

25、stian could convey a message to mankind.解析：选 C 细节理解题。根据 The Georgia Guidestones 部分第二段内容可知，巨石阵很神秘是因为没有人知道是谁建造了它。故选 C。9Why are people unwilling to enter the Bermuda Triangle?AIt is too remote from land.BThe chance of surviving is slim there.CThere are supernatural forces in the area.DAll transportatio

26、ns have disappeared there.解析：选 B 推理判断题。根据 Bermuda Triangle 部分第一段第二句可知，在百慕大三角经常有飞机、轮船和小船失踪；由此可推知，在百慕大三角人们幸存的可能性很小，所以许多人不愿意进入百慕大三角地带。故选 B。610What can we know about Loch Ness Monster?AIt existed in the 6th century AD.BIt is said to have a long neck and a large head.CIt has been living in Loch Ness Lake

27、 for a long time.DPeople havent reached an agreement on its existence.解析：选 D 细节理解题。根据最后一段第一句可知，关于水怪的故事始于公元 6 世纪，并不是说水怪出现在公元 6 世纪，故排除 A 项；根据最后一段第二句中的“with a small head”可知，B 项错误；根据最后一段倒数第二句可知，大多数科学家都不相信有这种水怪生活在尼斯湖中，故排除 C 项；根据最后一段最后一句可知，D 项“人们对它的存在没有达成一致意见”符合原文。故选 D。.阅读七选五Too often an inappropriate vie

28、w gets around us that it is our physical conditions that make us happy or unhappy. As a consequence, physical conditions have been overstated._1_， that is, good standard of living, high goals that we want to obtain, surrounding ourselves with a nice house, nice car, nice clothes, etc. _2_.

33、feEthey should not control your happiness in this momentFWe may think this is the key to our happinessGthey dont realize how to get happy语篇解读：本文是一篇议论文。本文谈论的是人们认为的幸福实际上并没有给人们带来幸福，作者就如何才能得到真正的幸福提出了自己的观点。1选 C 根据上文中的“physical conditions”及下文中的 “good standard of living .nice clothes”可知，C 项“我们通过努力掌控我们身边美好的

34、物质条件来获取幸福”与上文相呼应，与“that is”后面的解释也一致。故选 C。2选 F 根据语境可知，很多时候当我们拥有了良好的生活标准，实现了我们想要的目标，拥有了漂亮的房子、车子、衣服时，我们可能就认为这是幸福的关键所在了。F 项“我们可能会认为这就是幸福的关键了”衔接上文，并与下文构成转折，符合语境。故选F。3选 B 根据语境可知，此处分析了不快乐的人的心理。根据“because they have not obtained their goals”可知，许多人不快乐是因为没有达到目标，and 连接和前面并列的内容。B 项“他们没有拥有生活中想要的”也是人们不快乐的原因，并且和下文联系紧密。故选 B。4选 G 上文提到，拥有了良好物质条件的人仍然感到不幸福，没有达到目标的人也感到不幸福，此处作者给出他们感到不幸福的理由，因为“他们没有意识到如何获得快乐” 。由此可知，G 项与上文衔接紧密。故选 G。5选 E 上文提到，本文传递的信息就是要让你明白，你的欲望会告诉你，在生活中要看重什么。由 however 可知，后面的内容应与前面的叙述形成对比，所以 E 项“这时这些欲望不应该左右你的幸福感”符合语境。故选 E。8
