2013高考英语二轮阅读理解（四月）训练（2）及答案i believe that animals possess greater intelligence than most people think. but plants? ive never considered the possibility of plant intelligence. the idea seems absurd.yet ive had friends argue that plant intelligence might exist. what are the differences between plants and animals? they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.new research suggests that plants communicate via networks. plant communication is not a new idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.recent research from vidi researcher josef stuefer at the radboud university nijmegen shows that plants have their own chat systems that they can use to warn each other. therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.many herbal plants such as strawberries and clovers (三叶草)naturally form networks.individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). these connections enable the plants to share information with each other via internal channels. they are therefore very similar to computer networks. but what do plants chat to each other about?recently stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . if one of the plants is attacked by caterpillars (毛虫)，the other members of the network are warned via an internal signal. once warned, the intact (完好无损的)plants strengthen their chemical and mechanical (机体的)resistance so that they are less attractive to advancing caterpillars. thanks to this early warning system, the plants can stay one step ahead of their attackers. the research has shown that this significantly limits the damage to the plants.again, i dont believe this reflects intelligence, but its is certainly fascinating.17.the author thinks that the plant communication_.a.is absolutely a new idea b. is a sign of plant intelligence c.is related to animal communication d.is interesting and fascinating18.which of the following statements about the research is not true?a.most plants have no chat system and are passive organisms.b.individual plants can also remain connected with each other.c.the communication between clover plants can protect them from damage.d.the research is the first to show how clover plants warn each other.19.the authors attitude towards plant intelligence is _.a. unconcerned b. doubtfulc. positive d. hopeful20.whats the best title for the passage?a.does plant communication really exist?b.some discoveries about clover plantc.does plant communication imply intelligence?d.a new study on plant communication参考答案 17-20 dabc*结束aso long as teachers fail to distinguish between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. teaching children to read is not passing reading on to them. it is certainly not endless hours spent in activities about reading. douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible.”teaching and learning are two entirely different processes. they differ in kind and function. the function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. teaching is also a public activity: it can be seen and observed.learning to read involves all that each individual does to make sense of the world of printed language. almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.if teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge? smith has one principal rule for all teaching instructions. “make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”when the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.41. the problem with the reading course as mentioned in the first paragraph is that _.a. it is one of the most difficult school coursesb. students spend endless hours in readingc. reading tasks are assigned with little guidanced. too much time is spent in teaching about reading42. the teaching of reading will be successful if _.a. teachers can improve conditions at school for the studentsb. teachers can enable students to develop their own way of readingc. teachers can devise the most efficient system for readingd. teachers can make their teaching activities observable43. the word “scrutiny” in para.3 most probably means “ _”a. inquiry b. observation c. control d. suspicion44. according to the passage, learning to read will no longer be a difficult task when _.a. children become highly motivatedb. teacher and learner roles are interchangeablec. teaching helps children in the search for knowledged. reading enriches childrens experience45. the main idea of the passage is that a. teachers should do as little as possible in helping students learn to readb. teachers should encourage students to read as widely as possiblec. reading ability is something acquired rather than taughtd. reading is more complicated than generally believed参考答案 41-45dbbac *结束 bthe biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. in the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. the source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.rtca, an organization which advises the aviation(航空) industry, has recommended that all airlines ban such devices from being used during “critical” stages of flight, particularly take-off and landing. some experts have gone further, calling for a total ban during all flights. currently, rules on using these devices are left up to individual airlines. and although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. the difficulty is predicting how electromagnetic fields might affect an aircrafts computers. experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. but, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.the fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. as worrying, though, is the passenger who cant hear the instructions to turn off his radio because the musics too loud.46. the passage is mainly about _.a. a new regulation for all airlines.b. the defects of electronic crashesc. a possible cause of aircraft crashesd. effective safety measures for air flight47. what is said about the over 100 aircraft incidents in the past 15 years?a. they may have been caused by the damage to the radio systems.b. they may have taken place during take off and landing.c. they were proved to have been caused by the passengers portable computers.d. they were suspected to have resulted from electromagnetic interference.48. few airlines want to impose a total ban on their passengers using electronic devices because _. a. they dont believe there is such a danger as radio interference.b. the harmful effect of electromagnetic interference is yet to be proved.c. most passengers refuse to take a plane which bans the use of radio and cassette players.d. they have other effective safety measures to fall back on. 49. why is it difficult to predict the possible effects of electromagnetic fields on an airplanes computers?a. because it is extremely dangerous to conduct such research on an airplane.b. because it remains a mystery what wavelengths are liable to be interfered with.c. because research scientists have not been to produce the same effects in labsd. because experts lack adequate equipment to do such research.50. it can inferred from the passage that the author _.a. is in favor of prohibiting passengers use of electronic devices completelyb. has overestimated the danger of electromagnetic interferencec. hasnt formed his own opinion on this problemd. regards it as unreasonable to exercise a total ban during flight参考答案 46-50cdbca*结束ceveryone gathered around and paddy read out loud, slowly, his tone growing sadder and sadder. the littleheadline said: boxerreceives liff sentence.frank cleary, aged 26, professional boxer, was today found guilty of the murder of albertcumming, aged 32, laborer, last july. the jury (陪审团) reached its decision after only ten minutes, recommending the most severe punishment to the court. it was, said the judge, a simple case. cumming and cleary had quarreled violently at the harbour hotel on july 23rd and police saw cleary kicking at the head of the unconscious cumming.when arrested, cleary was drunk but clear-thinking.cleary was sentenced to life imprisonment with hard labour. asked if he had anything to say, cleary answered, “just dont tell my mother.”“it happened over three years ago,” paddy said helplessly. no one answered him or moved, for no one knew what to do. “just dont tell my mother,” said fee numbly. “and no one did! oh, god! my poor, poor frank!”paddy wiped the tears from his face and said. “fee , pack your things. well go to see him.”she half-rose before sinking back, her eyes in her small white face stared as if dead. “i cant go,”she said without a hint of pain, yet making everyone feel that the pain was there.“it would kill him to see me. i know him so wellhis pride, his ambition. let him bear the shame alone, its what he wants.weve got to help him keep his secret.what good will it do him to see us?”paddy was still weeping, not for frank, but for the life which had gone from fees face, for the dying in her eyes. frank had always brought bitterness and misfortune, always stood between fee and himself.he was the cause of her withdrawal from his heart and the hearts of his children.every time it looked as if there might be happiness for fee, frank took it away.but paddys love for her was as deep and impossible to wipe out as hers was for frank.so he said.“well, fee, we wont go. but we must make sure he is taken care of.how about if i write to father jones and ask him to look out for frank?” the eyes didnt liven, but a faint pink stole into her cheeks. “yes, paddy, do that.only make sure he knows not to tell frank we found out. perhaps it would ease frank to think for certain that we dont know.”10. which of the following is true according to the passage?a. frank was found guilty of murder because he was a pro
