B 解析： 1.C 【解析】全文通过介绍蜘蛛、蜻蜓和花朵的行为与天气的关系，主要说明了动植物能够显示天气变化的迹象。选项C准确地概括了文章的中心思想。 2.D 【解析】文章第三句明确指出：“If a spider is building its web outside, it often means sunny weather is on the way.” 因此，蜘蛛在室外结网通常意味着晴天即将到来。 3.A 【解析】文章中间部分提到：“If dragonflies are flying very low, it might mean the air is heavy and rain could come.” 所以，蜻蜓低飞是因为空气潮湿沉重，可能预示着下雨。 4.C 【解析】文章后半部分说明：“Some flowers, like tulips, close their petals before a rainstorm to protect themselves.” 因此，暴风雨前，一些花朵会合拢花瓣。 5.B 【解析】文章最后一段建议读者：“Next time you go outside, look around. Watch your nature friends. You can be a weather detective too!” 这与选项B“观察自然界的伙伴，成为一名天气侦探”的意思完全一致。 短文翻译 大自然的小天气播报员 你知道吗？小动物和植物也能告诉我们天气的秘密哦！它们就像大自然里的小小播报员！ 快看蜘蛛！如果你看到蜘蛛在外面织网，通常意味着晴天要来了。蜘蛛可不喜欢湿漉漉的网。也要留意蜻蜓。当它们飞得很低时，可能很快就要下雨了，因为空气变得沉甸甸的。就连花朵也会给我们提示呢。有些花在下暴雨前会合上花瓣，好保护自己。 这些小小的迹象学起来可有意思了。下次你出门的时候，记得仔细观察四周。只要留心观察大自然的朋友们，你也能成为一名天气小侦探！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
