Many animals move from one place to another at certain times of the year, 1.　which　 is called migration. Every autumn, 2.　millions　(million) of North American monarch butterflies begin their journey.

Its population 9.　has crashed　(crash) by as much as ninety percent in the last few years because of human activities. The research on the monarch's behavior has however led to a greater awareness of this creature. By doing more research, the monarch butterfly can keep 10.　its　(it) place in the natural world for a long time to come. 学科网（北京）股份有限公司 $$
