2017·全国卷Ⅱ·阅读理解D篇——对接课标主题：自然灾害与防范，安全常识与自我保护
When a leafy plant is under attack, it doesn't sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked. It's a plant's way of crying out. But is anyone listening？Apparently. Because we can watch the neighbors react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other Scientists don't know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn't a true, intentional back and forth.
Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear. Our senses are weak. There's a whole lot going on.

(六)在语境中赏表达之美
1．(赏用词之美)Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get.
赏析：句子运用getting bitten表达被动，“get＋过去分词”可以表示突然发生而未曾料到的情况，此处get更利于强调动作和进行两层含义。两个形容词particular和neighboring(高级词汇)的使用很好地限定了特性和范围，表意具体、清晰。
2．(赏意境之美)Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear.Our senses are weak.There's a whole lot going on.
赏析：句子描绘出了一个鉴于我们的感官的局限性，超出我们视听范围的、正在发生着很多事情的“world”，并使用了“far busier, noisier and more intimate”等进行修饰说明，从而引发读者无限的想象，激发读者对地球与宇宙奥秘进行探索的渴望。
3．(赏修辞之美)①They pump out perfumes designed to attract different insects who are natural enemies to the attackers.Once they arrive, the tables are turned.The attacker who was lunching now becomes lunch.
②Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself.Perhaps the neighbors just happened to “overhear” the cry.
赏析：句①the tables are turned运用了比喻的修辞手法，用“桌子翻了(局势发生了逆转)”这一具体、浅显、熟悉的情境把自然界“正在吃午餐的袭击者现在变成了午餐”这么一种情境说明得浅显易懂，给人以鲜明的印象。
句②运用了拟人的修辞手法，用描写人的词来描写物，通过made a cry of pain，talking to itself, overhear赋予物以人的动作、行为、思想、感情、活动。能使读者对所表达事物产生鲜明的印象，产生强烈的感情，引起共鸣，令文章更生动形象。
