6、ular 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

7、when being attacked .Its a plants way of crying out.But is anyone listening？Apparently.Because we can watch the neighbours 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

8、to the attackers.

9、ause they heard the alarm and knew what to do. Does this mean that plants talk to each other? Scientists dont 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”

10、the cry. So information was exchanged, but it wasnt 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. Theres a whole lot going on.语篇解读：研究发现，植物受到昆虫攻击时，会通过两种方式实施自我保

15、说的预测自然灾害，文中没有提及；C项属于曲解文意，原文说的是“Does this mean that plants talk to each other? Scientists dont know.”，不是C项所说的“有意识地谈话”。由原文中的“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 itseff.”可知第一个遭受袭击的植物的本意并不是为了帮助邻居，故D项错误。答案B4What can

17、考)Crime fighters could have a new tool at hand. Researchers have developed a cuttingedge technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by law enforcement.DNA testing is commonly used for identification because DNA is unique to each individual (个体

18、). However, environmental and chemical processes can degrade DNA, limiting its usefulness over time. Protein (蛋白质) in hair, on the other hand, is more stable than DNA but can also have variations (变体) that may be unique to the individual.“Our analysis process can be used universally，” says Ms. Huang

19、. “One of our samples (样本) even included dyed hair and the test was 100 percent accurate. The test was able to distinguish East Asians, Caucasians and South Asians.”Dr. Beauchemin says she has got in touch with law enforcement agencies about using the new technology. She is also planning to collect

23、rad Hart?AChemical materials. BProtein in hair.CDNA variations. DBlood samples.解析细节理解题。根据最后一段中的“This method will be a gamechanger”并结合第二段内容可推知，Brad Hart认为通过鉴定头发中的蛋白质来辨明一个人的身份是最有用的，故选B。gamechanger在此处表示“力挽狂澜者”。答案B7Whats the advantage of the proteinbased identification over DNA testing?AStability. BPopu

24、larity.CSecurity. DConvenience.解析细节理解题。根据第二段的最后一句“Protein (蛋白质) in hair, on the other hand, is more stable than DNA but can also have variations (变体) that may be unique to the individual”可知，以头发里的蛋白质为基础的检测手段与DNA检测相比最大的优势就是其稳定性，故选A。答案A8What can be inferred from the last paragraph of the text?ADNA test

25、ing will soon reach its full potential.BProteinbased identification remains to be improved.CProteinbased identification has replaced DNA testing.DDNA testing develops as rapidly as proteinbased identification.解析推理判断题。根据最后一段可知，这种新的技术还有待改善，故选B。答案B.七选五阅读填空(2018云南高中毕业生统一检测一)Courage is a personality qual
