Have you ever experienced huinantian, or lasting humid(潮湿的) weather?
Huinantian is a special weather condition in southern China. It normally appears in spring when the temperature begins to rise, and the humidity quickly increases. Before it arrives, there are usually a few cold days, with a temperature below 12 ℃. As the cold air goes away, warmer air quickly comes, and the temperature rises, creating a lot of water vapor(水蒸气). Small water drops can be seen on windows and walls. For example, if the temperature is below 12 ℃ from March 7th to 9th but suddenly rises on March 10th, then huinantian will appear on March 10th.
During huinantian, the humid weather makes it easy for bacteria(细菌) to grow. Food goes bad easily, clothes stay wet, and sofas can get moldy(发霉的). Things like televisions may break down when they get wet inside, which can be dangerous for people to turn them on. It can also make people feel tired and sick. Catching a cold is prevalent during this time, as the temperature changes quickly. Although the weather troubles people a lot, for nature, it can be helpful. Thanks to the humid weather, plants can grow better with enough water and warmer air.
To cut down the trouble caused by the lasting humid weather, scientists suggest that people in the south should close their windows in the morning and evening. At the same time, they should use an air conditioner to remove water from the air. It's also useful to put newspapers on the floor, on tables, and at the door to take in water and wet air.

解析
【分析】
第1题需结合原文中回南天的温度形成条件：回南天出现前（7-9日）温度低于12℃，之后温度突然上升，据此分析四幅图的温度变化选出符合条件的；第2题需结合语境推测划线词含义，匹配选项；第3题需梳理全文核心内容，选择贴合的标题。
【解析】
1. 根据原文：回南天出现前7-9日温度低于12℃，10日温度突然上升。观察四幅图：A图中8-9日温度约10℃（低于12℃），10日温度上升，符合条件；B图温度稳定无上升，C、D图温度呈下降趋势，均不符合，故第1题选A。
2. 划线词所在句意为“这段时间感冒很prevalent”，结合回南天温度变化快的语境，感冒是常见情况，“common”（常见的）符合，故选B。
3. 全文围绕回南天（潮湿天气）的形成、影响及应对展开，A范围过大，B、C仅涉及局部内容，D贴合主旨，故选D。
