第一篇 Volunteers are being recruited(征募) to eat raw potatoes in the first human trials of a vaccine grown in genetically engineered vegetables. Researchers in Texas hope that people who eat the potatoes will be protected against common gut(肠，肠子) infections. They believe this technique could prove to be a cost-effective way of growing vaccines in developing countries where such diseases are still killers. Other researchers previously succeeded in using similar techniques to produce potential vaccines Now Hugh Mason and his colleagues at Texas A & M University(得克萨斯农业及机械大学) their plant vaccines on mice and plan to recruit 15 volunteers for a human trial. The team first tested the technique in tobacco plants. They took a strain of Escherichia coli(大肠杆菌) bacteria that causes food poisoning, and identified the part of the poison which binds to its victims gut cells. They then used a modified plant bacterium called Agrobacterium tumefasciens to transfer the segment of DNA which manufactures the binding protein into the tobacco plant. Under normal circumstances, these bacteria transfer packets of DNA into plant cells to force the plant to manufacture the nutrients they need. But in the modified bacteria, the DNA package includes the gene to pro- duce the binding protein. Once the foreign DNA segment was incorporated(结合，合并) into the tobacco's own DNA, the bacteria were killed off with antibiotics. Mason's team then grew these modified tobacco plants and found that they produced the E. coli binding protein. Proof of success came when the tobacco leaves were mashed up(捣碎) and squirted into the stomachs of mice. Mason says that within days the mice started producing specific antibodies to the E. coli poison, but suffered no ill effects from digesting the binding protein. Mason then produced genetically engineered potatoes and fed these to mice, with similar results. Mason's team have used plants to produce vaccines against a number of other infectious agents. For example, they have made a vaccine using a protein from the shell of the Norwalk virus, which causes diarrhoea(腹泻) in children. A third vaccine has also been produced in tobacco using a surface protein from the hepatitis B virus. But Mason says that so far they have only been able to produce small amounts of it in potatoes. Although a vaccine already exists against hepatitis B, a cheaper plant version could make mass immunisation(群众性免疫) possible. One problem with growing potatoes to produce vaccines is that cooking tends to destroy the protein component of the vaccine, so they must be eaten raw. Mason thinks that bananas may be a better option. "One banana could potentially produce a whole host of different vaccines," says Mason. The purpose of this text is______。 A. to prove that doctors don't like vegetables B. to amuse the reader by telling some funny things C. to describe how vegetables can grow vaccines for their own use D. to tell the reader about a cheaper way of growing vaccines

希望得到珍贵的宝石吗？那就去黑洞附近碰碰运气吧。天文学家El前在观测中发现，一些特大质量的黑洞就如同宇宙中的“宝石工厂”，喷射出大量的水晶、红宝石和蓝宝石。这一发现将揭开构成宇宙的第一批恒星的尘埃的来源之谜，同时也为生命的物质之源找到了起点。据美国《科学日报》10月10日报道，一个由多国研究人员组成的小组利用美国国家航空航天局（NASA）的斯皮策太空望远镜对一个编号为PG2112+059的类星体进行了观测。它位于距离地球约80亿光年的一个星系中央。研究人员发现了沙子、玻璃、水晶、大理石和红宝石之类的矿物存在的迹象。由于这些物质在太空的恶劣的环境中无法长时间保留，因此这表明它们是刚形成的。 天文学家认为，星际尘埃逐渐聚集形成了恒星、行星、小行星、彗星等天体，随后才有了地球上的生命体。如今分布在宇宙角落的星际尘埃被认为是与太阳类似的巨大古老恒星在演化到超新星阶段衰亡爆炸时产生的，但是在137亿年“高龄”的宇宙的形成之初，形成那些原始恒星的尘埃又从何而来呢？ 一种观点认为，这些尘埃来自类星体。这种有“宇宙怪物’’之称的天体发现于上世纪六十年代，它的光谱似行星状星云但又不是星云，外形像星团又不是星团，发出的射电如星系又不是星系，它的内部呈螺旋状结构，中心是质量超大的黑洞，周围环绕着尘埃密布的环状星云。科学家认为它们是已知的最为活跃明亮的、正在形成中的星系，黑洞的强大吸引力将物质吸引进去，而由此产生巨大气压又形成“黑洞风”将物质吹离。就是在这场从未停歇的宇宙“拔河比赛”中，催生了恒星和新元素的出现。 最新的观测结果为这一理论提供了有力的证据。研究报告的主要作者、英国曼彻斯特大学的西斯卡·马克维克·肯普说：“我们惊讶地发现那些刚形成的尘埃是从特大质量的黑洞中吹出的风中来的。世界万物最终都来自宇宙尘埃，这揭开了我们来自哪里的所有疑问。”另一名研究小组成员、洛杉矶加州大学的莎拉·盖拉格尔则表示：“类星体就像《芝麻街》中的‘甜饼怪’，它们以风的形式喷射出的物质似乎比它们吸入的物质更多。” 这项研究的报告将发表在本月出版的《天体物理学杂志》上。研究人员还计划在其他类星体周围寻找尘埃的踪迹以进一步证明他们的发现，他们认为，也有可能类星体并不是早期宇宙唯一的尘埃来源。马克维克·肯普表示：“在某些环境下，超新星可能对尘埃形成更重要，而类星体可能在另外一些环境中显得作用更大。” 第 86 题 “由于这些物质在太空的恶劣的环境中无法长时间保留，因此这表明它们是刚形成的”这句话的用意何在？（） <img src='https://img2.soutiyun.com/ask/uploadfile/2439001-2442000/7d187ccd60fca26ce4a2ab0d08087ab2.gif' />
