答案与解析：
1. B。细节类。题干直接引用原文，故答题时先锁定引文位置。“It interrupts the natural order”是答题线索，既然是打乱了自然顺序，说明现在已经没有多少家庭保留这个传统做法了。
2. C。细节类。此题与上题出自同一段，要注意题干中的EXCEPT，并理解作者所说的反话，wi-fi只是作者打的比方，而不是春季大扫除的内容。
3. A。推理类。从作者列出的各种活动可以看出她意在说明有很多活动暂时还不会发生，所以是进行春季大扫除的好机会。
4. D。推理类。注意题中出现的“biologist”是定位关键词，另外EXCEPT问的是非正确选项，需用排除法。A和D语义相反，所以也可以通过逻辑判断直接选定错误理解是D。
5. B。态度类。“Wow”和“exclaim”表明了这个高兴的态度，“You will?”表明了犹豫疑惑的态度。
