Every living thing needs to reproduce. Reproducing means creating more members of your group. In order for plants to reproduce, they have to spread their seeds to other areas. Plants have developed all kinds of ways to do this.
The simplest way is gravity. Many seeds are inside of fruit. When a piece of fruit gets too heavy, it falls from a tree to the ground. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seed even farther away. Apples spread this way.
Other plants use wind to spread their seeds. Dandelions are a good example of this. Dandelion seeds are so light that when wind blows, it carries dandelion seeds to new places. Maple(枫树) seeds also use wind. Their seeds are connected with long, thin leaves that look like wings. When the seed falls from the tree, its "wings" help it fly farther from the tree.
Some animals help plants spread their seeds. The animals eat the seeds. While the seed is in the animal's body, it stays whole. When the seed leaves the animal, it's in a new place.
Ants also help spread seeds. Some seeds have a special smell that attracts ants. The ants bring the seeds back to their home, which of course is underground. They only eat part of the seed. They leave the rest of the seed underground. After that, the seed can start growing.

解析
【分析】
本题为英语阅读理解题，围绕植物种子的传播方式设置5道题目，需结合原文内容逐一分析：第6题是词义猜测题，需定位gravity的相关描述理解词义；第7、8题是细节理解题，需找到对应语句或梳理过程；第9题是文章结构题，需分析段落逻辑；第10题是主旨大意题，需概括全文核心。
【解析】
6. 词义猜测题：根据第二段“ The simplest way is gravity. Many seeds are inside of fruit. When a piece of fruit gets too heavy, it falls from a tree to the ground.”可知，gravity是使果实掉落的力，对应选项C。
7. 细节理解题：根据第三段“Maple(枫树) seeds also use wind.”可知，枫树靠风传播种子，对应选项B。
8. 细节理解题：根据最后一段蚂蚁传播种子的过程：蚂蚁被种子吸引→将种子带回地下→吃一部分种子→剩余种子留在地下，缺失环节为“它们把剩余的种子留在地下”，对应选项C。
9. 文章结构题：第一段总述植物有多种传播种子的方式，第二至第五段分别介绍不同传播方式，属于总分结构，对应选项A。
10. 主旨大意题：全文围绕植物传播种子的方法展开，核心内容是介绍植物传播种子的方式，对应选项A。
