　　答案与解析　

　　语篇解读　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 knowledge和include之间为动宾关系。

　　4.to/towards　考查介词。attitude to/towards表示“对……的态度”。

　　5.Obviously　考查词类转换。根据句子结构可知，此处应用副词作状语。

　　6.a　考查固定搭配。keep a diary表示“记日记”。

　　7.writing　考查动名词。by为介词，后接动名词作宾语。

　　8.and　考查固定句型。“祈使句＋and＋陈述句”为固定句型，and表示正向结果。

　　9.more　考查固定词组。what's more表示“而且”。

　　10.as　考查固定搭配。as well表示“也，还”。

　　五、阅读理解

　　(2015·北京卷)

　　Life in the Clear

　　Transparent 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 feet—as 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 they're eating it, or unless something is eating them.”

　　And they are as clear as glass. How does an animal become see­through? It's 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 doesn't absorb or scatter light, at least not very much. Light can pass through it without bending or stopping. That means a transparent object doesn't look very different from the surrounding air or water. You don't see it—you 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 doesn't have pigments, so its tissues won't absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.

　　Animals are built of many different materials—skin, fat, and more—and 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 they're 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.

　　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 groups

　　B. can be easily damaged

　　C. appear only in deep ocean

　　D. 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 extremely 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. gradually

　　C. 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 to ________.

　　A. change the direction of light travel

　　B. gather materials to scatter light

　　C. avoid the absorption of light

　　D. 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 water

　　B. stay see­through even after death

　　C. produce more tissues for their survival

　　D. 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
