Humans have feelings, and guess what? A new study says plants can sense their environment and answer to stress, just like animals.
Scientists used a machine to watch plants' reactions when they were treated in different ways. When people watered a plant, the machine drew smooth, calm lines. It showed a calm reaction, just like how people feel when they relax. But when someone shook the plant or blew smoke near it, the lines became sharp and shaky. This shows plants might "feel" stress!
A scientist acted meanly—he pretended(假装) to cut leaves with scissors. The machine's lines jumped wildly as he came near! However, when other scientists walked past the same plant, the machine stayed quiet. It seemed the plant only reacted to the "dangerous" person!
Another experiment tested if plants care about other living things. Live fish were dropped into hot water nearby. Surprisingly, the machine recorded strong reactions right away, as if the plants sensed the pain of dying animals.
But how do plants "feel"? They don't have brains, but their cells can send tiny signals when touched. For example, if you tickle a plant's roots, its leaves might curl up!
So what can we do? One gardener said her flowers bloomed brighter when she played soft music. Though we don't fully understand plants yet, treating them with care is always a good idea.
A. Plants might too!
B. Sing to your plants!
C. The most exciting test was about danger.
D. The machine recorded how the plants changed.
E. Plants given kind words grow 20% taller than silent ones.
F. Scientists think plants have a secret connection to all life.

文章大意:本文主要探讨了植物是否具有类似人类的感知能力。
41. A 解析:根据空格前“Humans have feelings, and guess what?”及空格后“A new study says plants can sense their environment and answer to stress, just like animals.”可知,首句以设问引出“人类有情感”,空后提及植物有情感的发现。选项 A“植物也可能有!”符合语境。故选 A。
42. D 解析:根据空格前“Scientists used a machine to watch plants’ reactions when they were treated in different ways.”可知,这里介绍了用机器观察植物反应的实验方法,故空处需具体说明机器的作用。选项 D“机器记录植物如何改变。”符合语境。故选 D。
43. C 解析:根据空格后“A scientist acted meanly—he pretended to cut leaves with scissors. The machine’s... the ‘dangerous’ person!”可知,这里描述了假装剪叶的危险实验。选项 C“最令人兴奋的测试是关于危险的。”符合语境。故选 C。
44. F 解析:根据空格前“Another experiment tested if plants care about other living things. Live fish were dropped into hot water nearby. Surprisingly, the machine recorded strong reactions right away, as if the plants sensed the pain of dying animals.”可知,该段通过“植物对濒死动物的反应”实验,故空处引出对植物与生命关联的推测。选项 F“科学家认为植物与所有生命有秘密联系。”符合语境。故选 F。
45. B 解析:根据空格后“One gardener said her flowers bloomed brighter when she played soft music.”可知,这里举例了播放轻柔音乐善待植物的方法,故空处会与用音乐善待植物相关。选项 B“为你的植物唱歌!”符合语境。故选 B。
