AAlthough it has been revealed in recent years that plants are capable of seeing, hearing and smelling, they are still usually thought of as silent.But now, for the first time, Itzhak Khait and his colleagues at Tel Aviv University in Israel found that tomato and tobacco plants made sounds at frequencies humans cannot hear when stressed by a lack of water or when their stem is cut.Microphones placed 10 centimetres from the plants picked up sounds in the ultrasonic(超声波的) range of 20 to 100 kilohertz, which the team says insects and some mammals would be capable of hearing and responding to from as far as 5 metres away.A moth(蛾) may decide against laying eggs on a plant that sounds water-stressed, the researchers suggest.Plants could even hear that other plants are short of water and react accordingly, they guess.Plants exposed to drought stress have been shown to experience cavitation—a process where air bubbles(气泡) form, expand and explode inside tissue that transports water.These explosions produce sound, but they have only ever been recorded using devices directly connected to the plant.On average, drought-stressed tomato plants made 35 sounds an hour, while tobacco plants made 11.When plant stems were cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15.Unstressed plants produced fewer than one sound per hour, on average.The researchers trained a machine-learning model to distinguish differences between the plants’ sounds and the wind, rain and other noises of the greenhouse, correctly identifying in most cases whether the stress was caused by dryness or a cut, based on the sound’s intensity(强度)and frequency.Water-hungry tobacco appears to make louder sounds than cut tobacco, for example.Enabling farmers to listen for water-stressed plants could “open a new direction in the field of precision agriculture”, the researchers suggest.They add that such an ability will be increasingly important as climate change exposes more areas to drought.Anne Visscher, working at the Royal Botanic Gardens, Kew, in the UK, warns that the results can’t yet be broadened out to other stresses, such as salt or temperature, because these may not lead to sounds.In addition, there have been no experiments to show whether moths(飞蛾）or any other animal can hear and respond to the sounds the plants make, so that idea remains speculative for now, she says.6．What does the new study find about plants?A．Stressed plants tend to lack water.B．The stressed plants can make sounds.C．Some plants can take in humans’ sounds.D．Some plants can have a bad effect on animals.7．What can we learn about cavitation according to paragraph2?A．It may contribute to the plants’ sounds.B．It may lead to plants experiencing drought.C．It is determined by the number of air bubbles.D．It was identified and recorded for the first time.8．How many sounds does the tobacco plant make one hour on average when cut?A．35B．11C．25D．159．What does paragraph4 mainly talk about?A．why some tobacco makes louder sounds.B．why the surroundings are vital to plants.C．how important the sound’s intensity and frequency are.D．how to distinguish between the sounds to know what the stress is.10．What can best replace the underlined word “speculative” in the last paragraph?A．reasonable B．tentative C．inspiring D．ridiculous【答案】6．B7．A8．D9．C10．B【解析】【分析】本文是说明文。
