15、读学习习惯会影响学习效果，本文就如何养成良好的学习习惯给我们提出了建议。1.saying考查词类转换。由不定冠词a可知此处应用saying(谚语，格言)。2.shows考查动词的时态、语态和主谓一致。此处陈述的是客观事实，应用一般现在时；句子的主语为“An apple a day keeps the doctor away”，谓语动词用第三人称单数形式，且主语与show为主谓关系，故填shows。3.included考查过去分词。high scores and abundant knowledge included为独立主格结构，作状语，high scores and abundant kno

17、ent 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 Joh
18、nsen, 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
19、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
20、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
21、 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. Acco
22、rding 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 scat
23、ters. 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
24、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
25、 an active process. When they die, they turn a nontransparent milky white.语篇解读本文是一篇说明文，向读者介绍了透明的动物，并解释了它们透明的原因。1.According to Paragraph 1, transparent animals _.A. stay in groupsB. can be easily damagedC. appear only in deep oceanD. are beautiful creatures答案与解析B考查细节理解。根据文章第一段第三句话“Most of them are ex
26、tremely delicate and can be damaged by a simple touch”可知透明的动物很容易被伤害，故答案为B项。2.The underlined word “dead” in Paragraph 3 means _.A. silently B. graduallyC. regularly D. completely答案与解析D考查词义猜测。根据第三段中第四句话前半句其他的动物吸收光，可以猜出后面是完全地阻止光的传播，画线单词的意思应为“完全地”，故答案为D项。3.One way for an animal to become transparent is
27、to _.A. change the direction of light travelB. gather materials to scatter lightC. avoid the absorption of lightD. grow bigger to stop light答案与解析C考查细节理解。根据第五段第一句话可知，要想变得透明，动物需要避免它的身体吸收光或散射光，故答案为C项。4.The last paragraph tells us that larger transparent animals _.A. move more slowly in deep waterB. sta
28、y seethrough even after deathC. produce more tissues for their survivalD. take effective action to reduce light spreading答案与解析D考查推理判断。根据最后一段可知，较大的动物保持透明是一个积极的过程，而根据前文我们知道保持透明需要减少光的扩散，故答案为D项。六、短文改错(2016辽宁五校高三联考)This morning, I was jogging in the park when I caught the sight of a wallet on a bench.
