Question

【题目】 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 (丝腺) 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 (撕裂的韧带) 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."

【1】The man-made silk can be used (o do many things EXCEPT .

【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

【4】C

【解析】

文章大意：本文主要介绍了科学家们制造出一种和蜘蛛丝线一样坚韧的材料，这种材料将造福人类。

【1】细节理解题。根据第二段第三句They think it can help people get well after a bum. 他们认为它能帮助人们在流浪后康复。根据第二段第五句Plane makers and makers of protective clothing also see many uses for the new silk. 飞机制造商和防护服制造商也看到了这种新丝绸的许多用途。可知，故答案为C。

【2】细节理解题。根据Senior researcher Anna Rising spoke about how ▲ the new discovery could be.高级研究员安娜·瑞斯谈到了这个新发现的重要性。根据simple简单的；important重要的；awful糟糕的；boring无聊的。结合句意可知，此空应填important，故答案为B。

【3】细节理解题。根据第三段第三句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. 将来，这可能使人造丝的工业生产成为可能，人造丝可以用于许多领域，使我们的生活更加美好。可知，故答案为A。

【4】主旨大意题。根据A. Spider silk is good for humans蜘蛛丝对人类有好处；B. Scientists from Sweden are great瑞典的科学家是伟大的；C. Making spider silk is now possible现在制造蜘蛛丝是可能的。D. Making scientific discoveries is hard科学发现是困难的。结合文章大意可知，故选C。
