Although 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, they have been recorded making ultrasonic cries when stressed, which researchers say could open up a new field of precision agriculture where farmers listen for water-starved crops.
Itzhak Khait and his colleagues at Tel Aviv University in Israel found that tomato and tobacco plants made cries 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 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 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 speculate.
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.
It is even possible to distinguish between the sounds to know what the stress is. The researchers trained a machine-learning model to discriminate 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 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.
“The suggestion that the sounds that drought-stressed plants make could be used in precision agriculture seems feasible if it is not too costly to set up the recording in a field situation,” says Anne Visscher at the Royal Botanic Gardens, Kew, in the UK.
She 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 or any other animal can hear and respond to the sounds the plants make, so that idea remains speculative（推测的）for now, she says.
1.The experiment by researchers at Tel Aviv University shows that_______.
A.tobacco plants make louder sounds than tomato plants when hurt

C.unstressed plants produced sounds of laughter when being watered

Three-Dimensional （3D） movies have been becoming more and more popular in recent years．It seems 3D TV sets may be going into family households in the near future．While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say．
"There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist （眼科医师） in Chicago．He said in a 3D movie, these people face a completely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters．
In normal vision, each eye sees things at a slightly different angle．"When that gets processed in the brain, that creates the perception （感觉） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校准的） in the same way that their eyes and brain are．"If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs
to exert （竭尽全力）," he said．
Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all．He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images．
Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off．
Heineman said older 3D technology used two film projectors（放映机）, one that projected a left-eye image and one that projected a right-eye image．Three-D glasses would allow viewers to see a different image in each eye．
"People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said．
Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems．
"By going to a single digital projector, those problems were solved," he said．Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty （新鲜事物）．"I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said．
1.The text is mainly about ____．
A．the reasons why people like 3D movies
B．how to improve 3D technology
C．the development of 3D technology in recent years
D．causes of headaches and nausea when people watch 3D movies
2.The underlined phrase "took off" could be replaced by "______"．
A．became popular
B．flew in the sky
C．left hurriedly
D．removed one's clothes
3.This article implies that _____．
A．people do not like new things like 3D movies
B．3D TVs will completely take the place of old TV sets
C．3D technology is the most important technology ever
D．those with eye muscle problems should not watch 3D movies
4.We can learn from what Rosenberg said in the last paragraph that
A．a single digital projector could solve all the problems with 3D technology
B．people will gradually become comfortable with 3D movies and TVs
C．the appeal of 3D movies and "TVs may fade
D．most people will actually enjoy the 3D experience

Online shopping is increasing popular among people in recent years. Some people liked to buy goods online. And I don’t like it, because online shopping is more reliable than the traditional sale. Firstly, some dishonest merchant offer customers to false information online. Secondly, consumers can’t feel the items that is usually presented by means of pictures. This means the items delivering may differ from which consumers expect. As a result, they may risk returning the items at their own expense. Thirdly, the items might be damaged during delivery. In word, online shopping isn’t reliable at all.

How has smoking been controlled in recent years?
People were asked to stop smoking in a range of public places—such as doctors’ surgeries, cinemas, theatres and churches—over the second half of the 20th century but it was after the King’s Cross Underground fire on November 18, 1987, caused by a cigarette end which resulted in 31 deaths, that restrictions on smoking in public places gained rapid and widespread acceptance.
How did a ban on smoking in public places come into place?
In 1998 the Smoking Kills White Paper set out a national strategy to reduce smoking prevalence (流行) and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later.
What is the current law?
Any person who smokes in enclosed public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises (营业场所) to permit others to smoke in them.
How was it received?
It was welcomed by most organizations—except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (法律，法规) before it was carried out, while others have gone beyond its basic requirements.
All railway facilities, including platforms, footbridges and other areas—whether or not fitting the definition of an enclosed public space—are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are.
How has it been forced?
Compliance (服从) in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying “work” vehicles. They said that a total ban on smoking in vehicles would end this confusion.
Has it improved health?
Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke.
1.When did the first law come out to ban smoking in public places?
A. 1987. B. 1998. C. 2004. D. 2006.
2.Which of the following behaviors may NOT be against the law?
A. Jack often smokes in the office when he is alone.
B. A taxi driver is smoking with a lady in his car.
C. Tom smokes while thinking of his future at home.
D. Max smokes for relaxation during time-out in the stadium.
3.Who might feel unhappy about the law according to the article?
A. A restaurant owner. B. A company manager. C. A car owner. D. A policy maker.
4.What can you infer from the article?
A. Most heart diseases have been proved to be linked to passive smoking.
B. A new law will soon come out with a total ban on smoking in vehicles.
C. The 1987 fire has convinced more people that smoking is bad for health.
D. Most of the school grounds are not smoke-free, as it is not banned in the law.
