|题目:雨天犯困的原因|体裁:说明文|难度:★★★★|建议用时:7 分钟|正确率: /10|
Do you feel sleepy on rainy days? If the answer is yes, you're not a 1.alone Many people feel the same way. But do you know why?
One of the r 2.reasons is that there's little sunshine on rainy days. Our brain will have less serotonin(血清素) and more melatonin(褪黑素) if there's not e 3.enough sunlight. Serotonin helps us feel good, while melatonin makes us feel sleepy. As a result, we may want to go to s 4.sleep.
The humidity(湿度) of a rainy day is a 5.another reason. As it rains, the air becomes wetter than usual. It's more difficult for our sweat(汗水) to dry in weather like this, so our body has to work h 6.harder to stay cool. This can make us feel tired.
Moreover, the s 7.sound of rain, a type of pink noise, will make us feel sleepy too. Like white noise, pink noise includes all the sound frequencies(频率) humans can hear, but it has fewer high frequencies t 8.than white noise. This makes pink noise sound softer. Studies show that people's brain waves(电波) will become fewer when they hear pink noise, so they'll fall asleep more e 9.easily.
What can you do if you don't like that feeling? Well, you can get as much natural light as possible and keep y 10.yourself busy. Also, you can use a machine to make your room dry. In this way, you won't feel sleepy any more.

答案： 【解析】：
这是一道英语短文填空题，主要考查学生对词汇、语法和上下文理解的综合运用能力。题目给出了短文的大部分内容，但其中一些单词的首字母或部分字母被省略，需要学生根据上下文和首字母提示，补全这些单词。这要求学生对英语词汇有深厚的积累，同时能够理解短文的整体意思和上下文联系，才能准确填写出缺失的单词。
【答案】：
1. alone；根据上下文，这里说的是“如果你答案是肯定的，那么你并不孤单”，很多人都有同样的感觉，所以填alone。
2. reasons；短文在解释雨天犯困的原因，所以这里填reasons，表示“原因”。
3. enough；根据上下文，雨天阳光少，导致大脑血清素减少，褪黑素增多，所以这里填enough，表示“足够的”。
4. sleep；由于血清素减少，褪黑素增多，所以我们可能会想去睡觉，填sleep。
5. another；前文已经提到一个原因，这里说的是“另一个原因是”，所以填another。
6. harder；由于空气湿度大，汗水更难蒸发，身体需要更努力工作来保持凉爽，所以填harder。
7. sound；后文提到“a type of pink noise”，说明这里说的是雨的声音，所以填sound。
8. than；这里在比较粉红噪音和白噪音的高频部分，所以填than。
9. easily；根据上下文，人们在听到粉红噪音后，脑电波会减少，从而更容易入睡，所以填easily。
10. yourself；这里说的是“让自己保持忙碌”，所以填yourself。
