Question

【題目】 A group of scientists from Sweden have unlocked one of nature's biggest secrets. The scientists have worked out how spiders make such strong silk when they build their webs. The silk that spiders make is strong and even tougher than steel. Being able to produce man-made spider silk has long been a dream of many scientists. Now, researchers from the Swedish University of Agricultural Sciences have, step by step, developed a method that works. They've found that the materials for webs arc in a spider's silk gland (絲腺) as protein. The gland has a level of acidity (酸度) that helps make the protein into very strong silk. The researchers reported that they could produce man-made spider silk by copying the process.

The new man-made silk could be very useful to humans. Doctors are interested in it. They think it can help people get well after a bum. Some doctors believe the new silk could be used to take the place of the torn ligaments (撕裂的韌帶) in the body. Plane makers and makers of protective clothing also see many uses for the new silk.

Senior researcher Anna Rising spoke about how ▲ the new discovery could be. She said, "This is the first successful example of copying spider silk-making process. In the future, this may allow industrial production of man-made silk, which can be used in many fields and make our life much better. The silk could become a valuable material for us."

【3】According to Anna Rising, the new material .

A.will improve our life a lotB.can help fight air pollution

C.will take the place of many other materialsD.can help us make more scientific discoveries

【4】What's the best title for the passage?

A.Spider silk is good for humansB.Scientists from Sweden are great

C.Making spider silk is now possibleD.Making scientific discoveries is hard

Answer 1

【3】A

【4】C

【解析】

文章大意：本文主要介紹了科學(xué)家們制造出一種和蜘蛛絲線一樣堅韌的材料，這種材料將造福人類。

【1】細(xì)節(jié)理解題。根據(jù)第二段第三句They think it can help people get well after a bum. 他們認(rèn)為它能幫助人們在流浪后康復(fù)。根據(jù)第二段第五句Plane makers and makers of protective clothing also see many uses for the new silk. 飛機(jī)制造商和防護(hù)服制造商也看到了這種新絲綢的許多用途。可知，故答案為C。

【2】細(xì)節(jié)理解題。根據(jù)Senior researcher Anna Rising spoke about how ▲ the new discovery could be.高級研究員安娜·瑞斯談到了這個新發(fā)現(xiàn)的重要性。根據(jù)simple簡單的；important重要的；awful糟糕的；boring無聊的。結(jié)合句意可知，此空應(yīng)填important，故答案為B。

【3】細(xì)節(jié)理解題。根據(jù)第三段第三句In the future, this may allow industrial production of man-made silk, which can be used in many fields and make our life much better. 將來，這可能使人造絲的工業(yè)生產(chǎn)成為可能，人造絲可以用于許多領(lǐng)域，使我們的生活更加美好�？芍�，故答案為A。

【4】主旨大意題。根據(jù)A. Spider silk is good for humans蜘蛛絲對人類有好處；B. Scientists from Sweden are great瑞典的科學(xué)家是偉大的；C. Making spider silk is now possible現(xiàn)在制造蜘蛛絲是可能的。D. Making scientific discoveries is hard科學(xué)發(fā)現(xiàn)是困難的。結(jié)合文章大意可知，故選C。
