解析
【分析】
本题为自然生态主题的英语七选五题型，解题思路为：先通读全文把握语篇核心（中国保护迁徙白鹤的措施），再逐个分析空白处前后的语境逻辑（如承接、因果、目的、指代等关系），匹配对应选项。第1空需承接白鹤迁徙至鄱阳湖的结果，说明鹤在此过冬的情况；第2空需承接鄱阳湖涝旱交替的问题，引出食物不足的后果；第3空需承接政府种莲藕的行为，说明其目的；第4空需承接1140个栖息地的内容，说明栖息地的类型；第5空需引出后文提到的法律内容。
【解析】
1. 第1空：前文说明白鹤迁徙至鄱阳湖，C选项“约95%的鹤在那里过冬”承接上文迁徙的目的地，符合语境，故选C。
2. 第2空：前文提到鄱阳湖有时涝有时旱，F选项“这两种情况都会导致鹤没有足够的食物”承接上文的气候问题，引出下文的解决措施，故选F。
3. 第3空：前文说政府种植莲藕，E选项“这样，它们为鹤提供冬季的食物”解释种植莲藕的作用，符合逻辑，故选E。
4. 第4空：前文提到1140个重要栖息地，A选项“它们大多是湿地”承接上文的地点，后文说明湿地的作用，故选A。
5. 第5空：后文提到法律相关内容，G选项“为保护湿地，2022年6月1日出台了湿地保护法”引出下文的法律规则，故选G。
