1.1 what: (研究对象,研究结论)
Talking plants have long been a thing of myths and legends. Many cultures have stories of talking trees that give advice as well as warnings to people. Alexander the Great and Marco Polo were said to have visited such a tree in India. And in some modern stories, such as the film Avatar, trees can communicate with animals and people.
With us long believing that talking plants are fantasy, new research has revealed something amazing: it appears that plants can communicate after all.
Tip:要准确把握科普类说明文的主题,首段是关键,阅读过程要特别留意语篇标志词(如however,but等)的含义,还要留意“new research/recent study/scientists”以及“long believe,think/show/suggest/indicate/reveal”等引出观点与研究的标志词。


how:(研究的结论如何得出,研究过程)
It has been known for some time that plants use chemicals to communicate with each other. This happens when a plant, say a bean plant, gets attacked by insects. The plant releases tiny amounts of chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I'm being attacked!” When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals. Some of these chemicals drive insects away. Others attract insects - the wasps! The wasps kill the insects that are eating the bean plants. Scientists hope to learn more about this plant warning system, so that we can use it to grow crops without pesticides.
More surprisingly, plants also use sound to communicate. People can't hear these sounds, but plants are making them. Some plants make noises with their roots. Corn and chilli plants do this. T...Some trees make clicking noises when there is not enough water, indicating drought is arriving.
Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest. Scientists call this system the “wood wide web” It is in some ways similar to the Internet we use. .... within the wood wide web.

③The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding (编码) experiences into different categories. For example, one participant’s experience of “We sat and listened to the waves at the beach for a while” was assigned the categories “sitting at beach” and “listening to waves.”

4.Which of the following is the best title for the text
A.More Women Are Exercising to Prevent Dementia
B.Middle-Aged Women Need to Do More Exercise
C.Fit Women Are Less Likely to Develop Dementia
D.Biking Improves Women’s Cardiovascular Fitness
①The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New research found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia(失智症)in later life—and if they did, it came on a decade later than less sporty women.

D. A reasonable doubt about the research process.
⑤Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of “f” and “v” increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today.

14. What did the follow-up study focus on
A. The size of the groups. B. The dominant members.
C. The discussion process. D. The individual estimates.
④In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates Did they follow those least willing to change their minds This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together.” Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain the potential implications for group discussion and decision-making are enormous.

(2020·全国Ⅰ卷,阅读理解D)
 ①The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown, Ohio, for example, discovered that greener areas of the city experienced less crime. In another, employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
②The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further—changing the actual composition of plants in order to get them to perform diverse, even unusual functions. These include plants that have sensors printed onto their leaves to show when they're short of water and a plant that can detect harmful chemicals in groundwater. “We're thinking about how we can engineer plants to replace functions of the things that we use every day,”explained Michael Strano, a professor of chemical engineering at MIT.
③One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano's team found that they could create a faint light for three and a half hours. The light, about one thousandth of the amount needed to read by, is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self powered street lamps.
④In the future, the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one off treatment that would last the plant's lifetime. The engineers are also trying to develop an on and off “switch”where the glow would fade when exposed to daylight.
⑤Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)—such as the distance from a power plant to street lamps on a remote highway—a lot of energy is lost during transmission(传输). Glowing plants could reduce this distance and therefore help save energy.
