閱讀理解awhen a leafy plant is under attack, it doesnt 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. its a plants 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 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” 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(親密的)than the world we can see and hear. our senses are weak. theres a whole lot going on.1.what does a plant do when it is under attack?a.it makes noises.b.it gets help from other plants.c.it stands quietly.d.it sends out certain chemicals.2.what does the author mean by“the tables are turned”in paragraph 3?a.the attackers get attacked.b.the insects gather under the table.c.the plants get ready to fight back.d.the perfumes attract natural enemies.3.scientists find from their studies that plants can.a.predict natural disastersb.protect themselves against insectsc.talk to one another intentionallyd.help their neighbors when necessary4.what can we infer from the last paragraph?a.the world is changing faster than ever.b.people have stronger senses than before.c.the world is more complex than it seems.d.people in darwins time were more imaginative.答案1.d2.a3.b4.cbbenjamin west, the father of american painting, showed his talent for art when he was only six years of age. but he did not know about brushes before a visitor told him he needed one. in those days, a brush was made from camels hair. there were no camels nearby. benjamin decided that cat hair would work instead. he cut some fur from the family cat to make a brush.the brush did not last long. soon benjamin needed more fur. before long, the cat began to look ragged(蓬亂). his father said that the cat must be sick. benjamin was forced to admit what he had been doing.the cats lot was about to improve. that year, one of benjamins cousins, mr. pennington, came to visit. he was impressed with benjamins drawings. when he went home, he sent benjamin a box of paint and some brushes. he also sent six engravings(版畫) by an artist. these were the first pictures and first real paint and brushes benjamin had ever seen.in 1747, when benjamin was nine years old, mr. pennington returned for another visit. he was amazed at what benjamin had done with his gift. he asked benjamins parents if he might take the boy back to philadelphia for a visit.in the city, mr. pennington gave benjamin materials for creating oil paintings. the boy began a landscape(風(fēng)景)painting. william williams, a well-known painter, came to see him work. williams was impressed with benjamin and gave him two classic books on painting to take home. the books were long and dull. benjamin could read only a little, having been a poor student. but he later said, “those two books were my companions by day, and under my pillow at night.”while it is likely that he understood very little of the books, they were his introduction to classical paintings. the nine-year-old boy decided then that he would be an artist.5.what is the text mainly about?a.benjamins visit to philadelphia.b.williams influence on benjamin.c.the beginning of benjamins life as an artist.d.the friendship between benjamin and pennington.6.what does the underlined sentence in paragraph 3 suggest?a.the cat would be closely watched.b.the cat would get some medical care.c.benjamin would leave his home shortly.d.benjamin would have real brushes soon.7.what did pennington do to help benjamin develop his talent?a.he took him to see painting exhibitions.b.he provided him with painting materials.c.he sent him to a school in philadelphia.d.he taught him how to make engravings.8.williams two books helped benjamin to .a.master the use of paintsb.appreciate landscape paintingsc.get to know other paintersd.make up his mind to be a painter答案5.c6.d7.b8.d第三節(jié) 任務(wù)型閱讀cycling in asia: opening new roads to sustainabilityasias rising middle class may be driving the increase in car ownership, leading to traffic congestion and air pollution in the regions cities, but this status symbol may be slowly giving way to an old lovecycling.more asians are jumping on a bicycle for fresh air and to lead a more environmentally-friendly and active lifestyle in recent years as staying sedentary inside a car for hours on end could take a toll on ones health, and be hard on the wallet because of the high cost of fuel and maintenance.in a new study of vehicle ownership in 44 countries by pew research center, households around the world own bicycles more than motorcycles and cars. japan and thailand rank second and third in terms of bike ownership globally, although these two countries also rank high in car ownership, with 81 per cent and 51 per cent of their populations owning at least one vehicle. china is also leading the world in the number of bike-sharing schemes, with about 170 bike-sharing systems operating in the country. singapore, known for its efficient public transport system but having no established culture of cycling as a transport option, is one of the countries now keen to change that. it is spending $43 million on bike lanes and cycling facilities as part of a national cycling plan.adb (asian development bank) is looking at including bicycles as part of a public transport network in some cities in southeast asia through bike-sharing schemes. many cities around the world including amsterdam and copenhagen have shown the successful integration of bike-sharing programmes in public transport systems.in another form of bike-sharing, cycling has also become a solution to help poor students in rural communities access bicycles as a form of sustainable transport. a non-profit group bike for the philippines is lending bicycles for free to help poor students in the country who still need to walk three kilometres to school because of lack of access to public transport or who have no ability to pay for its high costs.united kingdom-based bamboo travel says their clients are increasingly interested in cycling tours when they plan their trips to asia.“in the last few years we have seen demand for cycling excursions grow quickly.and we find a lot of our clients now request some time cycling in places where before they used to do sightseeing by car.clients of all ages have become healthier and more environmentally conscious in recent years and cycling has grown as a result,” ewen moore, sales director at bamboo travel, tells eco-business.“theyre very attractivea fun and healthy way to do some sightseeing,” said moore.cycling in asia: opening new roads to sustainability
