(2019·山东潍坊模考)语篇类型：说明文 主题语境：植物
Plants cannot run or hide, so they need other strategies to avoid being eaten. Some curl up their leaves; others produce chemicals to make themselves taste bad if they sense animals drooling (垂涎) on them, chewing them up or laying eggs on them—all signals of an attack. New research now shows some flora can feel a plant－eating animal well before it launches an attack, letting a plant prepare a preemptive (抢先的) defense that even works against other pest species.
高考英语二轮复习训练题
When ecologist John Orroek of the University of Wisconsin—Madison sprayed snail slime—a liquid the animals release as they slide along—into soil, nearby tomato plants appeared to notice. They increased their levels of an enzyme (生化酶), which is known to prevent plant-eating animals. “None of the plants were ever actually
attacked.” Orroek says. “We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.”
Initially Orroek found this defense worked against snails; in the latest study, his team measured the slimy warning impact on another potential threat. The investigators found that hungry-caterpillars (毛虫), which usually eat tomato leaves greedily, had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance. This nonspecific defense may be a strategy that benefits the plants by further improving their overall possibilities of survival, says Orroek, who reported the results with his colleagues in March in Oecologia.
The finding that a snail's approach can cause a plant response that affects a different animal made Richard Karban curious, a plant communications expert, who was not involved in the study. “It is significant that the plants are responding before being damaged and that these cues are having such far-ranging effects，” Karban says. The research was comprehensive, he adds, but he wondered how the tomato plants felt chemicals in snail slime that never actually touched them.
“That's the million-dollar question，” Orroek says. He hopes future research will make out the mechanisms that enable plants to sense these relatively distant cues.
篇章导读：本文是一篇说明文。新的研究表明，植物能感知到动物即将发动的攻击。
1.What can be a suitable title for the text？ A.Watchful Plants
B.Greedy Animals
高考英语二轮复习训练题
C.A Snail's Approach D.A Defense Attack
答案：A 标题判断题。由第一段第三句中的“New research now shows some flora can feel a plant－eating animal well before it launches an attack”可知，新的研究显示，植物能感知到动物即将发动的攻击。故A选项“警惕的植物”为最佳标题。
2.John Orroek sprayed a liquid into soil to ________.
A.make nearby tomato plants grow better B.give tomato plants a warning C.keep plant-eating animals away
D.inform plant-eating animals of danger
答案：B 细节理解题。由第二段中的“We just gave them cues that suggested an attack was coming”可知是为了警示它们攻击即将来临。
3.Why is the example of “caterpillars” mentioned in Paragraph 3？ A.To introduce another animal. B.To confirm the result of the study. C.To appeal to people to protect animals. D.To analyse different resistance chemicals.
答案：B 推理判断题。由第三段第二句可知，饥饿的毛毛虫对接触过蜗牛黏液的叶子不再有食欲，所以判断出第三段提到毛毛虫的例子是为了确认研究结果。
4.What does Richard Karban really want to know？ A.How tomato plants become aware of danger.
B.What the chemicals in the snail slime are. C.Whether the research is of practical value. D.What the finding of the research is.
答案：A 推理判断题。由倒数第二段最后一句中的“but he wondered how the tomato plants felt chemicals in snail slime that never actually touched them”可知，但是他想知道番茄植物是如何感受到蜗牛粘液中的化学物质，而这些化学物质从未真正接触过它们。所以判断出Richard想知道番茄植物是如何感知危险的。
strategy n. 策略 defense n. 防卫；辩护 activate vt. 激活；使活动
第四段第一句：The finding that a snail's approach can cause a plant response that affects a different animal made Richard Karban curious, a plant communications expert, who was not involved in the study.
译文：蜗牛的接近会引起植物对不同动物的反应，这种发现使Richard Karban
