词义猜测题(一)据逻辑,猜词义(2015北京C)Life in the ClearTransparent animals let light pass through their bodies the same way light passes through a window.These animals typically live between the surface of the ocean and a depth of about 3,300 feetas far as most light can reach.Most of them are extremely delicate and can be damaged by a simple touch.Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone.They never touch anything unless theyre eating it, or unless something is eating them.”And they are as clear as glass.How does an animal become seethrough? Its trickier than you might think.The objects around you are visible because they interact with light.Light typically travels in a straight line.But some materials slow and scatter(散射)light, bouncing it away from its original path.Others absorb light, stopping it dead in its tracks.Both scattering and absorption make an object look different from other objects around it, so you can see it easily.But a transparent object doesnt absorb or scatter light, at least not very much. Light can pass through it without bending or stopping.That means a transparent object doesnt look very different from the surrounding air or water.You dont see ityou see the things behind it.To become transparent, an animal needs to keep its body from absorbing or scattering light.Living materials can stop light because they contain pigments(色素) that absorb specific colors of light.But a transparent animal doesnt have pigments, so its tissues wont absorb light.According to Johnsen, avoiding absorption is actually easy.The real challenge is preventing light from scattering.Animals are built of many different materialsskin, fat, and moreand light moves through each at a different speed.Every time light moves into a material with a new speed, it bends and scatters.Transparent animals use different tricks to fight scattering.Some animals are simply very small or extremely flat.Without much tissue to scatter light, it is easier to be seethrough.Others build a large, clear mass of nonliving jellylike(果冻状的)material and spread themselves over it.Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does.They need to look uniform.But how theyre doing it is still unknown.One thing is clear:for these larger animals, staying transparent is an active process.When they die, they turn a nontransparent milky white.文章大意:你见过透明生物吗?本文介绍了透明的海洋生物。作者为我们介绍了物体之所以不能透明的原理,从而让我们理解没有什么器官组织的透明生物能够保持透明的奇特性。1According to Paragraph 1, transparent animals_.Astay in groupsBcan be easily damagedCappear only in deep oceanDare beautiful creatures答案:B细节理解题。根据文章第一段第三句Most of them are extremely delicate and can be damaged by a simple touch.可知,透明生物非常脆弱,轻轻的触碰都可能使其致命,故选B项。2The underlined word “dead” in Paragraph 3 means_.AsilentlyBgraduallyCregularlyDcompletely答案:D词义猜测题。文中画线词所在句的句意为:其他的物质吸收光线,完全阻挡光的传播途径。由后面一句中的look different fromother objects around it以及you can see it easily可知,物体不能透明是因为散射光线和吸收光线,光线被完全吸收时变得不透明。由此可以判断句中的dead是副词,意为“完全地”。3One way for an animal to become transparent is to_.Achange the direction of light travel Bgather materials to scatter lightCavoid the absorption of lightDgrow bigger to stop light答案:C细节理解题。根据第五段第一句To become transparent, an animal needs to keep its body from absorbing or scattering light.可知,动物要想变透明就需要阻止身体吸收或散射光线,故C项是变透明的一个方法。4The last paragraph tells us that larger transparent animals _.Amove more slowly in deep waterBstay seethrough even after deathCproduce more tissues for their survivalDtake effective action to reduce light spreading答案:D推理判断题。文章最后一段第一句说较大的透明动物面临巨大挑战,因为它们必须尽可能让所有身体组织像水一样降低光线传播的速度。故选D项。(二)由解释,猜词义(2015湖北B)What Theresa Loe is doing proves that a large farm isnt a prerequisite for a modern growyourown lifestyle.On a mere 1/10 of an acre in Los Angeles,Loe and her family grow,can (装罐) and preserve much of the food they consume.Loe is a master food preserver,gardener and canning expert.She also operates a website,where she shares her tips and recipes,with the goal of demonstrating that everyone has the ability to control whats on their plate.Loe initially went to school to become an engineer,but she quickly learned that her enthusiasm was mainly about growing and preparing her own food.“I got into cooking my own food and started growing my own herbs(香草) and foods for that fresh flavor,”she said.Engineer by day,Loe learned cooking at night school.She ultimately purchased a small piece of land with her husband and began growing their own foods.“I teach people how to live farmfresh without a farm,”Loe said.Through her website Loe emphasizes that “anybody can do this anywhere.”Got an apartment with a balcony (阳台)?Plant some herbs.A window?Perfect spot for growing.Start with herbs,she recommends,because “th
