How Plants and Animals Know the Weather
主题:趣味知识库 词数:159 建议用时:8分钟 语篇类型:说明文
Do you know that some plants and animals can tell us about the weather? They are like little weather reporters! Let’s find out how they do it.
Before it rains, you may see ants moving in a long line. They are carrying their food to a new home. Why? They know the rain is coming and their old home will get wet. Also, swallows (燕子) fly very low in the sky before rain. They do this because small bugs fly low when the air is wet. The swallows follow the bugs to get food.
Plants are smart, too. There is a shy plant called mimosa (含羞草). On sunny days, its leaves are open. But before a storm(暴风雨), its leaves close up. It is like the plant is saying, “Rain is coming!” Nature is really amazing. Next time you see these signs, you can tell your friends what the weather will be like!

答案及解析
答案:1. A 2. C 3. A 4. D 5. B
解析:
1. A 【解析】 文章中提到,蚂蚁在下雨前排成一条线移动,是因为它们原来的家会被雨水打湿。它们想要寻找一个干燥的新家。所以正确答案是A。
2.C 【解析】 燕子在下雨前低飞,是因为潮湿的空气让飞虫飞得很低。燕子为了寻找食物,就会跟着这些低飞的飞虫,所以也飞得很低。选项C正确地描述了这一因果关系。
3.A 【解析】 文章中明确写道:“在晴朗的日子里,它的叶子是张开的。” 这里的“它”指的是含羞草。因此,在晴天,含羞草的叶子是张开且宽大的。所以A选项正确。
4.D 【解析】 这篇文章主要讲述了动物(蚂蚁、燕子)和植物(含羞草)的行为如何预示天气的变化。它们的行为是大自然给我们的“天气预报”。因此,文章的中心思想是“大自然给了我们关于天气的迹象”。选项D最符合这个意思。
5.B 【解析】 文章说动植物是“聪明的”,因为它们能“告诉我们天气情况”。“聪明”在这里指的是它们有通过自身行为来预示天气的能力,这与“能够学习和理解”的能力相关。选项B最接近这个解释。
短文翻译
动植物如何感知天气
你知道吗?有些动植物能告诉我们天气的变化。它们就像小小的天气预报员!让我们来看看它们是怎么做的吧。
下雨前,你可能会看到蚂蚁排着长长的队伍在移动。它们正把食物搬到一个新家。为什么呢?因为它们知道快要下雨了,它们原来的家会变湿。同样,燕子在下雨前会飞得很低。它们这样做是因为空气潮湿时,小飞虫会飞得很低。燕子跟着这些小飞虫来获取食物。
植物也很聪明。有一种害羞的植物叫含羞草。在晴朗的日子里,它的叶子是张开的。但在暴风雨来临前,它的叶子会合拢起来。就好像这棵植物在说:“要下雨了!”大自然真是奇妙。下次你看到这些迹象时,就可以告诉朋友们天气将会怎样啦!
