walk again Newts 蝾螈 in the same situation on the other hand can grow limbs back on their own Scientists have known for a long time that certain animals can re grow limbs but they haven t quite figured out how these creatures do it Researchers have now come up with some new ideas Their work may give people the ability to regrow lost limbs The researchers started with two simple experiments when you cut a newt s leg at the ankle only the foot grows back when you cut off a leg at the very end the whole leg grows back In both cases the regrowth begins with stem cells Stem cells can develop into nearly any type of cell in the body How do a newt s stem cells know when to grow only a foot and when to regrow a whole leg This question relates to another mystery In newt s a cut off leg will grow back only if the nerve bundle 神经束 in it also grows back but if something prevents the nerve bundle from growing the stem cells at the wound won t re grow a new leg In its study a British team focused on a protein called n AG When the team prevented nerves in a limb from growing but added the n AG protein to stem cells in the limb the limb still regrew That protein seems to guide limb regrowth People have proteins that are similar to n AG Further research into these materials may someday help human limbs recover by themselves 16 A newt will regrow its leg if A its ankle was cut off but the nerve bundle was good B its leg was cut off and the nerve bundle stopped growing C its leg was cut off and the nerve bundle could grow back D its ankle and the nerve bundle could grow back 17 What do the underlined words these materials refer to A Nerve bundles and proteins B Proteins similar to n AG C Stem cells and proteins D Stem cells and nerve bundles 18 The first sentence of the passage A acts as a lead in 5 B shows where researchers got their new ideas C states the author s opinion D describes the result of researchers studies 19 What s the purpose of studying the newts A To find out whether newts would regrow after being cutting off B To find out the similarity between human and newts C To find out what is n AG D To find a way of helping human limbs recover by themselves 答案与解析 16 C 根据文章倒数第二段第二句 a cut off leg will grow back only if the nerve bundle in it also grows back 可知被割掉的肢体重新长出来的条件是其中的神 经束也能长回来 17 B 根据文章最后一段中的 People have proteins that are similar to 可知对这些类似于蛋白质的研究 科学家有一天能够帮助人类的肢体自动恢复 18 A 本文主要介绍对蝾螈肢体再生的研究 因此文章的第一句起引入话题的作用 19 D 从文章最后一句可以看出科学家对蝾螈研究的最终目的就是找到帮助人类肢体 自动恢复的方法 七选五 Students will need to use all of their skills in order to understand the reading
