解析
问题要求我们根据文章内容回答五个选择题。文章主要讨论了科学家们通过研究天气数据发现周末天气与工作日天气存在差异，并推测这种差异可能与人类活动导致的空气污染有关。
步骤 2：分析问题
1. 问题1询问周末的天气状况。根据文章第一段，周末天气多云且有雨，因此答案为A。
2. 问题2询问科学家们如何研究天气。根据文章第二段，科学家们研究了超过40年的天气数据，因此答案为C。
3. 问题3询问科学家们研究了多少个美国气象站的数据。根据文章第三段，科学家们研究了660个美国气象站的数据，因此答案为D。
4. 问题4询问“striking”一词的中文含义。根据上下文，科学家们注意到这种模式是明显的，因此答案为C。
5. 问题5询问周末天气与工作日天气不同的原因。根据文章最后一段，科学家们认为这种差异可能与人类活动导致的空气污染有关，因此答案为D。
