Ⅳ. Read and judge（爸爸和Xiaopu、Xiaojiang也在讨论天气对植物的影响。读一读，判断句子的对错，对的用T表示，错的用F表示）
Dad: Kids, there are many plant weather tricks around us. Do you know?
Xiaopu: Yes. For example, mimosa plants shrink when touched, but they also close on their own before rain because they “sense” humidity in the air!
Xiaojiang: Grandma said willow leaves flip upside down before rain!
Dad: Yes! Willow leaves have tiny hairs on their backs that catch the humidity in the air. When humidity rises, they flip to show the dry side!
Xiaotian: But how do plants know the weather’s changing, Dad?
Dad: Plants are super sensitive to temperature, light and humidity. For example, morning glories use light-sensitive cells to “decide” when to open or shut. They’re like natural temperature meters and humidity meters.
Xiaopu: So next time I’ll check the garden before leaving home to decide if I need an umbrella!
Dad: Haha. All of you will be “Plant Weather Experts”! Though plants give us clues, we should always check the real weather forecast by ourselves!
Xiaopu, Xiaojiang, Xiaotian: We will!
QUICK TIPS
含羞草一碰就会收缩，而且在下雨前它们也会自动合拢，因为它们能“感知”到空气中的湿度！
柳叶背面有细小的绒毛，能留住水分。当湿度升高时，它们就会翻转过来，露出干燥的一面！

【分析】
本题为英语阅读判断正误题，解题思路如下：①先通读全文，理解文章围绕“植物与天气的关联”展开的内容；②逐题提取题目中的关键信息（如含羞草、柳叶、植物的特性、牵牛花、天气预报等），以此为定位词回到原文找到对应语句；③对比题目描述与原文内容，完全一致则判断为T，存在不符则判断为F。
【解析】
1. 定位原文Xiaopu的表述：“mimosa plants shrink when touched, but they also close on their own before rain”，可知含羞草不仅触碰时收缩，下雨前也会自动合拢，题目中“only fold up when touched and don’t react to rain”与原文不符，故判断为F。
2. 定位原文Dad的表述：“Willow leaves have tiny hairs on their backs that catch the humidity in the air”，可知柳叶的绒毛在背面，题目中“on their fronts”与原文不符，故判断为F。
3. 定位原文Dad的表述：“Plants are super sensitive to temperature, light and humidity”，与题目描述完全一致，故判断为T。
4. 定位原文Dad的表述：“morning glories use light-sensitive cells to ‘decide’ when to open or shut”，与题目描述完全一致，故判断为T。
5. 定位原文Dad的表述：“we should always check the real weather forecast by ourselves”，说明不能仅依赖植物判断天气，题目中“we can only depend on plants”与原文不符，故判断为F。
