Scientists at Tel Aviv University have conducted a six-year study, proving that plants produce a noise in certain stressful situations. The plants make a high frequency clicking sound which cannot be heard by humans, and when they are lacking water, or being damaged, the clicks become far more regular. The plants could make various sounds, depending on whether they are thirsty or injured.
For the scientists’ research, some plants were placed in a soundproof box and recorded by two microphones. Some plants were badly in need of water, others were cut, and a control group was left undamaged. The researchers used AI technology to separate the noises. Being able to identify the particular calls of the plants up to 3-5 metres away, the technology successfully discriminated between the sounds made depending on whether the plants were dry or cut.
While farming has become a science itself, there’re still a lot of estimates involved. If farmers were able to receive accurate information directly from their crops, they could adopt a much more efficient method of care and also be able to better identify and control diseases in a crop. All this can be achieved by using microphones and sensors to translate this new information.
On average, the human ear can hear sounds up to around 20 kHz, whereas the sounds produced by plants are in the 40-80 kHz region, far beyond our hearing capabilities. However, the sounds produced by plants can probably be heard by various animals. Though this has yet to be proven, these creatures may use this information for their benefit, choosing which plants to eat, for example.
Furthermore, a study in 2014, led by Reda Hassanien of China Agricultural University in Beijing, proved that plants reacted to sound waves, with some plants significantly increasing their yield. While it’s still unknown if one plant could react to another’s noises, it seems likely. Indeed, the same research facility is now ready to test this assumption.
1．Which of the following can best replace the underlined word “discriminated” in Paragraph 2
A．Balanced. B．Compared.
C．Distinguished. D．Captured.
2．What benefit may farmers get from this research
A．Managing their crops purposefully and effectively.
B．Protecting their crops against diseases directly.
C．Adding to the variety of crops to some extent.
D．Saving their time on farming significantly.
3．What is now sure about the sounds produced by plants according to the researchers
A．They improve the crop production.
B．They go beyond humans’ hearing range.
C．They assist animals in searching for food.
D．They help plants communicate with each other.
4．What may future research focus on
A．Whether plants can react to each other’s sounds.
B．Whether creatures can react to sound waves.
C．How to judge the types of plants by sound.
D．How plants communicate with another’s noises.
5．The writer wrote the passage to tell us .
A．plants may help increase yield in farming by sound
B．plants can communicate like humans by various sounds
C．plants repeat the identical sound in the face of danger
D．plants can produce diverse sounds in difficult situations
五、课文语法填空：
Imagine mountains wrapped in silver water, shining in the spring sun. Summer s 1 the mountains turn bright green with growing rice. During autumn, these same mountains are gold, and in winter they are covered in s 2 of white frost. These are the colours of the Longji Rice Terraces.
These terraces were built by the local Zhuang and Yao people. R 3 as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top.
So why did these people go 4 so much trouble to turn the entire mountains into terraces Firstly, building the terraces meant that they could increase the areas in which they could grow rice. Secondly, the 5 terraces catch the rainwater and prevent the soil from being washed away.
But perhaps what is most significant is the way in which people have worked in 6 with nature to make these terraces and grow rice. The terraces are cleverly designed, with hundreds of waterways that 7 with each other. During the rainy season, it is along these waterways that rainwater moves down the mountains and into the terraces. The sun heats the water 8 turns it into vapour. This forms clouds from which rain falls down onto the mountain terraces once again.
Although modern technology could help produce more crops, these terraces still mean a lot to the local people for 9 traditions hold much value. Today, the Longji Rice Terraces attract thousands of visitors who come to admire this great wonder c 10 by people and nature working together.
