Unlike what you may imagine, taking good care of a plant can be difficult, especially when it comes to how to water a plant. Many people are not sure how often or how much they need to water their plants. Even some farmers may have the same problem. Luckily, a new technology called GrowStream can help them “talk” to their plants.
GrowStream is a watering system. Its tubes(管子) have special tiny holes in them. When plants need water, they will release(释放) chemicals(化学物质) through their roots. When the holes detect (察觉) these chemicals, they will open. The plants then get water from these holes. As the plants “drink” enough water, they stop releasing these chemicals. And that “tells” the holes to close back up and stop watering.
This system can help save 45 to 50 percent more water than common watering systems. It was created by a company called RDI. The company has brought the GrowStream system to many farms in South Africa. It is also testing the system in the US. It will be used to make the city greener while saving more water.
“GrowStream is more than just a technology,” said Jan Gould, CEO of RDI. “We want it to ‘talk’ to people too. It ‘says’ two things: The earth's natural resources(资源) are not so much, and we should take better care of the planet through new technology.”

答案
36. B 解析:细节理解题。根据第一段中“Many people are not sure how often or how much they need to water their plants.”可知,许多人不确定他们需要给植物浇水的频率或量。故选 B。
37. D 解析:细节理解题。根据第二段中“When the holes detect these chemicals, they will open. The plants then get water from these holes. As the plants ‘drink’ enough water, they stop releasing these chemicals.”可知,当这些孔检测到这些化学物质时,它们就会打开,然后植物从这些洞里吸收水分,当植物“喝”足够的水时,它们会停止释放这些化学物质,由此可见系统通过检测植物释放的化学物质的量来控制供水。故选 D。
38. A 解析:词义猜测题。根据画线词所在句“As the plants ‘drink’ enough water, they stop releasing these chemicals.”可知,当植物“喝”足够的水时,它们会停止释放这些化学物质,“they”指代上文提到的“植物”。故选 A。
39. C 解析:细节理解题。根据第三段中“This system can help save 45 to 50 percent more water than common watering systems.”可知,该系统可以比普通浇水系统节省 45%至 50%的水。故选 C。
40. D 解析:推理判断题。根据最后一段中“We want it to ‘talk’ to people too. It ‘says’ two things: The earth’s natural resources are not so much, and we should take better care of the planet through new technology.”可知,我们也希望它能与人们“对话”,它“说”两件事:地球的自然资源并不多,我们应该通过新技术更好地保护地球,所以新技术能帮助我们更好地保护地球有限的自然资源。故选 D。
