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 have usually 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(烘干机) to dry your clothes and blankets.

答案
7.D 8.A 9.C 10.B
解析
7. 定位文章第二段可知，回南天出现在气温逐渐回升的春季，暖空气冷却后会产生大量水汽，整体特征是温暖潮湿。A选项文中没有提及天天下大雨；B选项无相关表述；C选项气温低于12℃是回南天来临前的特征，并非回南天期间的天气特点，因此选D。
