一、单项选择。
1. It heavily yesterday. And it is still today. （）

A.rained；rain
B.rains；rainy
C.rained；rainy
D.raining；rained

C

第一空出现时间状语yesterday（昨天），句子需用一般过去时，动词rain的过去式为rained，可排除B、D选项；第二空前有be动词is，此处需要填入形容词作表语，rain的形容词形式是rainy，意为“下雨的”，排除A选项，最终选C。

2. Tengchong is a small village, we can see many tourists from all around the world. ()

A.Because
B.So
C.Although
D.If

C

先辨析各选项含义：A.Because表原因，B.So表结果，C.Although表让步，D.If表假设。分析句子逻辑：“腾冲是一个小村庄”和“我们能看到许多来自世界各地的游客”是让步转折关系，只有Although符合该逻辑。

3. Simon and his family feel after having a field trip. ()

A.tiring; tired
B.tiring; tiring
C.tired; tired
D.tired; tiring

D

本题考查形容词辨析：tired用于描述人的感受，意为“感到疲惫的”，第一空主语是Simon和他的家人，指人，所以填tired；tiring用于描述事物的属性，意为“令人疲惫的”，第二空修饰field trip这个事物，所以填tiring，对应选项为D。

4. The moonlight is coming in the window and it looks very beautiful. ()

A.across
B.through
C.with
D.into

B

辨析各选项介词用法：A.across指从物体表面横穿；B.through指从物体的内部空间穿过；C.with表示伴随、带有；D.into表示进入。月光是从窗户的内部空间穿透进来，符合语境的是through。

二、阅读理解。
Have you ever experienced “hui nan tian”, or ongoing(不间断的) wet weather?
“Hui nan tian” is a special kind of weather in Southeast China in spring, when it becomes warmer and warmer. Before it comes, there are usually a few cold days, with a temperature below 12 °C. After the cold air goes away, warmer air quickly comes and gets cooler, making a lot of water vapor(水蒸气). So you can see small water drops on windows and walls.
Ongoing wet 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). TV sets may break down when they get wet inside. It’s dangerous because you may get an electric shock(电击) when turning them on.

1. 细节理解题。根据第二段内容，回南天的形成顺序为：先出现几天气温低于12℃的寒冷天气（c），之后冷空气退去（b），暖空气迅速到来（a），随后暖空气降温（d），正确顺序为cbad，对应选项B。
2. 细节理解题。根据第三段“TV sets may break down when they get wet inside.”可知，电视是内部受潮才会故障，并非外部受潮就会停止工作，C选项表述错误，其余A、B、D三项均和原文内容相符，本题要求选不正确的表述，故选C。
3. 段落大意题。第三段介绍了回南天潮湿天气容易滋生细菌、食物变质、衣物家具发霉、电器受潮有触电风险等问题，第四段介绍了回南天期间人容易感冒的问题，两段都在讲述回南天会带来的各类问题，故选C。
4. 推理判断题。根据空格后“所以这段时间气温变化快，感冒是很常见的”，可推断空格处内容应和潮湿天气对人体的不良影响相关。A选项和后文“as the temperature changes quickly”语义重复，B选项和原文回南天发生在春天的表述不符，C选项的正面情绪和后文生病的内容矛盾，D选项“潮湿天气也会让人感到疲惫甚至生病”可以自然衔接后文内容，故选D。
