There are many things honeybees need to know in order to work together, to keep the beehive alive. They need to make honey, so they tell each other how to reach flowers.
How do bees know where to find the flowers? In 1943, Karl von Frisch, a scientist, found that bees communicate by dancing. Here's how it works: bees fly around looking for flowers. A flower's strong smell and bright colours attract the bee. When a bee finds those flowers, it goes back to the hive and does a special "dance". There are "round dances" that bees do when the flowers are close to the hive. There are also "waggle dances" which bees do when the flowers are far away. The bee acts in one of these ways to show other bees where the flowers are and how far away they are.
Bees also produce chemicals to communicate. If an animal like a bear goes near the beehive, the bees' bodies start to make these special chemicals. Other bees sense them and know that the hive is in danger. They all start to fly out to sting the animal and drive it away.
You can see there are many ways to communicate, and they are different from what people do. Next time you see a honeybee on a flower, think about how bees communicate with each other.

6. C
5. D
6. C
解析
4. 定位到文章第二段“There are 'round dances' that bees do when the flowers are close to the hive.”，可知蜜蜂发现离蜂巢近的花时会跳“圆舞”，对应选项D。
5. 文章第二段介绍蜜蜂通过跳舞交流，第三段介绍蜜蜂通过产生化学物质交流，故选项D表述正确；A选项与文中“they are different from what people do”不符；B选项与文中“work together”不符；C选项与文中“if an animal like a bear goes near the beehive, the bees' bodies start to make these special chemicals”不符。
6. 本文是关于蜜蜂交流方式的科普内容，这类内容最可能出现在科学网站上，对应选项C；奇幻故事、地理书、旅游杂志均不符合文章主题。
