Ⅳ. Read the passage and choose the best answers.
Plants Crying in Pain
Try to think about this: You sit down and begin to eat a tomato. Suddenly, the tomato starts to scream! This would never really happen. But a new study shows that plants make sounds when they are stressed.
Some scientists did the study. They used ultrasonic(超声的) microphones to record the sounds of tomato plants in boxes. They listened to three groups of plants.
The first two groups made sounds 30 to 50 times every hour. The third group only made the sound once every hour. “When tomatoes are not stressed at all, they are very quiet,” a professor said.
Scientists believed that animals and insects may listen to the sounds. For example, the sound can tell them that the plant is stressed and not good for laying eggs on. When an animal wants to eat plants, it can also use sound to choose which one to eat.
The scientists also listened to other crops such as wheat and corn. They also made more sounds when stressed. Scientists said it can help farmers in the future. They can better take care of the crops by “hearing” how plants feel.
(
A. what the new study found B. where the sound comes from
C. why scientists made the study D. how tomatoes find the sound
(
A. feel as stressed as the plants
B. know when to help the plants rest
C. find out the best plants to use or eat
D. protect themselves from dangerous plants
(
A. look after the crops better B. stay safe while planting
C. talk to their crops easily D. get more wheat than corn
(
A. Crops may grow better when we touch them often.
B. Farmers may eat more tomatoes after learning about the sound.
C. Scientists may study the sound better after watching the plants.
D. Tomatoes may make more sounds when we cut off their stems.

解析
【分析】
首先逐题梳理解题思路：24题需定位第三段内容，判断段落主旨；25题定位第四段，提取动物利用声音的相关信息；26题定位最后一段，查找研究对农民的帮助；27题需结合全文逻辑，排除不符合原文的选项，进行合理推断。
【解析】
24题：第三段详细介绍了三组番茄植物的发声频率差异，核心是呈现新研究的发现（受胁迫番茄发声更频繁），对应选项A；B选项“声音来源”、C选项“研究原因”、D选项“番茄找声音”均与第三段内容不符。
25题：第四段指出动物和昆虫可通过植物声音判断其是否受胁迫，从而选择适合产卵或食用的植物，选项C“找出合适的使用或食用植物”符合文意；A选项“感受植物的压力”、B选项“知道何时帮植物休息”、D选项“保护自己免受危险植物”均未在原文提及。
26题：最后一段明确说明该研究未来能帮助农民“通过‘听’植物的感受更好地照顾作物”，对应选项A；B选项“种植时安全”、C选项“轻松和作物交流”、D选项“比小麦多产”均与原文不符。
27题：A选项文中未提及触摸植物的影响；B选项无农民吃更多番茄的表述；C选项研究已开展，并非推断内容；D选项番茄被切断茎属于受胁迫状态，结合研究中“受胁迫植物会发声”的结论，可合理推断该选项正确。
