A group of scientists has found that some plants will scream in a high frequency(频率) when they are under stress(压力)．The scientists carried out the research on tomato plants and pepper plants by breaking their stems(茎) and cutting them off water. When the scientists started cutting the stems， they found that the plants started “screaming” between 20 and 100 kilohertz(千赫)．For the tomato plants，25 Mayday(求救信号) sounds were given out over an hour，and similarly，15 times from the pepper plants.The scientists believe that this scream was probably to warn other plants around and told them the bad was happening.When the scientists cut the plants off water，the tomato plants even cried more Mayday sounds with 35 times in an hour while the pepper plants just 11 times.The plants also acted differently to different kinds of stress.For example，the pepper plants gave out a stronger “scream” when people cut them off water.However，when there was no immediate(立即的) danger，they would scream less than once every hour. The group of scientists said that this changes the way we think of plants.Though they seem quiet，they will scream in fact.We just can't hear them because humans only can hear from 20 hertz to 20，000 hertz. ( )1.When will some plants scream according to the text? A．When the plants face pressure(压力)． B．When the plants grow freely with enough water and sunshine. C．When people pick up their fruits from them. D．When people water them. A 【主旨大意】本文提到植物遇到压力时同样会尖叫，只是由于声频 高于人类听力范围不被人注意。科学家分别拿西红柿树和辣椒树做 实验，当它们被剥夺水或者砍茎时会有不同次数和不同赫兹的尖叫。 细节理解题。根据第二段第一句可得知。 ( )2.The underlined word “warn” in Paragraph 3 means “______”． A．refuse the help from B．inform the danger of C．tell the differences from D．share happiness with B 词义猜测题。根据画线部分前的Mayday可得知。 ( )3.Which one is TRUE according to the text? A．The pepper plants screamed more times than the tomato plants in the test of cutting off stems. B．The tomato plants screamed fewer times than the pepper plants in the test of cutting off water. C．The tomato plants gave out a less strong “scream” when people cut them off water. D．When there was no immediate danger，they would also scream for thousands of times. C 看 解 析 细节理解题。根据第三段25、15与35、11几组数字可知A、B项错 误。根据the pepper plants gave out a stronger “scream” when people cut them off water.可知C项正确。根据when there was no immediate danger，they would scream less than once every hour.可知D项错误。 看 题 干 ( )4.Why can't people hear the scream of plants? A．Because their sound frequency is higher than humans' hearing. B．Because they will scream from 20 hertz to 20，000 hertz. C．Because they only scream beyond 100 kilohertz. D．Because they only scream below 20 hertz. A 细节理解题。根据最后一段最后一句We just can't hear them because humans only can hear from 20 hertz to 20，000 hertz.可知植物尖叫频率不在人类可听到的范围内。根据第三段第 一句When the scientists started cutting the stems，they found that the plants started “screaming” between 20 and 100 kilohertz.可知植物的尖叫频率比人类要高。 ( )5.What's the best title of the text? A．Animals' Scream in Nature B．Strange Frequency in Nature C．Silent Plants under Stress D．Plants' Scream under Stress D 标题归纳题。文章主要讲述植物在压力下会尖叫的 事实。 谢 谢 观 看 Thank you for watching!
