D
Many marine species(海洋物种) depend on specific routes to migrate(迁徙). The routes offer these seafaring travellers the right conditions, at the right time of year, to guide them through the oceans. We humans try to discover the routes and have drawn our own lines, but they are not clear to us because of unexpected changes in nature.
To find out the routes that migratory marine species regularly take, a research team of scientists in Australia and the US have now created an interactive map that shows the paths connecting ocean habitats(栖息地).
The new map, named the Migratory Connectivity in the Ocean(MiCO), collects data and makes it easier for scientists to see where migratory marine species may be falling into the paths. The database(数据库) includes information on 109 species, based on around 30 years of data, and shows where they are going to and from—including which species cross into whose national waters.
“MiCO connects almost 2,000 important habitats and shows the importance of cross-boundary teamwork,” says the research team. They find that all of the species recorded in MiCO have less protection at some point in their life history because of different situations in different countries. That means no country is able to fully protect migratory species if there is no help from others. “For example, green turtles nest in Costa Rica and migrate north through Nicaragua and out to islands in the Caribbean,” the team says. “Although largely protected in Costa Rica, it is allowed to fish for turtles in Nicaragua and huge numbers are lost off the coast there every year.”
MiCO works to provide useful knowledge on migratory connectivity to help protect marine species. In 2023, a UN report found climate(气候) changes are having a bad influence on migratory species. MiCO catches the information from different time periods and the team hopes it may be used to tell those changes in connectivity. MiCO is also expected to collect information on more migratory marine species because there is less than one-third of data collected now.
“So far, the migratory information revealed within the MiCO system only touches the surface of the true connectivity of the global oceans,” the team says.
42. How does the writer lead in the topic?

答案： D
文体：说明文
文章大意：本文主要介绍了一个名为MiCO的交互式地图系统，该系统主要用于追踪海洋物种的迁徙路线，并强调跨国合作对保护迁徙物种的重要性。
42 D 推理判断。根据第一段中“Many marine species depend on specific routes to migrate ... to guide them through the oceans.”和第二段内容可知，作者通过描述海洋物种依赖特定路线迁徙的背景信息，引出了借助MiCO系统进行的研究。
43 C 细节理解。根据第三段中“The new map，named the Migratory Connectivity in the Ocean(MiCO) ... shows where they are going to and from”可知，MiCO是一个展示海洋物种迁徙路线的数据库。
44 B 推理判断。根据第四段中“They find that all of the species ... if there is no help from others.”和绿龟的例子可推测出，作者通过介绍绿龟在不同国家保护差异的案例，说明跨国合作的重要性。
45 C 细节理解。根据第三段中“The database includes information on 109 species ... where they are going to and from”可知，MiCO收集的数据与物种迁徙路线相关。C项中“棱皮龟从印度尼西亚到俄勒冈州游了大约2万公里”符合这一特征。
