Have you ever experienced huinantian, or ongoing humid(潮湿的) weather? Here's everything about it.
Huinantian is a special kind of weather in south-east China in spring, when it becomes warmer and warmer. Before it comes, there usually has been a few cold days, with the temperature below 12℃. After the cold air goes away, warmer air quickly comes and gets cooler, creating a lot of water vapour. So you can see small water drops on windows and walls.
Ongoing 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). Electrical devices(电器设备) may break down when they get wet inside. It's dangerous because you may get an electric shock(电击) when turning them on.
Wet weather also makes people feel tired and even sick. Catching a cold is common during this time, as the temperature changes quickly.
Although the weather troubles people a lot, for nature, it can be helpful. Thanks to the humidity, plants can grow better with enough water and warmer air.
What to do on humid days
Make sure you close the door and windows, especially windows facing south. Morning and night are key times to stop wet air from getting into the room.
Put newspapers on the floor, on the table, and at the door to take in water and wet air.
Use an air conditioner(空调) to take away water from the air. Use a dryer to dry your clothes and blankets.

答案：7.D 8.A 9.C 10.B
解析：
7. 细节理解题。根据第二段内容可知，回南天出现在气温逐渐回升的春季，同时会产生大量水汽，整体特征是温暖潮湿的。A选项“每天都下大雨”、B选项“每三天就变天”文中均无相关表述；气温低于12℃是回南天到来之前的寒冷天气特征，并非回南天期间的状态，C错误，因此选D。
8. 细节理解题。根据第三段原文“Food goes bad easily”可知回南天里食物很容易变质，B选项“食物没有任何细菌”和文中“潮湿天气让细菌容易滋生”的表述矛盾，C、D选项文中没有提及，因此选A。
9. 主旨大意题。第3段介绍了回南天会导致细菌滋生、食物变质、家具发霉、电器漏电等问题，第4段介绍了回南天会让人疲惫、容易生病，两段都在讲回南天会带来的各类问题，对应选项C。A选项是第二段的内容，B选项是文末应对方法部分的内容，D选项是第二段介绍的回南天潮湿的成因，均不符合题意，因此选C。
10. 细节理解题。根据第五段原文“Thanks to the humidity, plants can grow better with enough water and warmer air.”可知空气中的湿度可以帮助植物更好地生长，B表述正确。A选项文中无相关表述；第四段提到回南天期间人们很容易感冒生病，C表述错误；回南天给人带来困扰，但对植物生长有好处，D表述错误，因此选B。
