That's likely true. _____1_____ For example, as one 2013 study showed, when people found their wandering thoughts more interesting, their moods actually improved while mind-wandering. Similarly, other studies have found that thinking about people you love or thinking more about your potential future than about what happened in the past produces positive results.How you use mind-wandering may also be important. ___2___ It has been mostly unexplored in previous research, but likely has distinct effects. As one 2017 study found, people who use daydreaming for self-reflection typically have more pleasant thoughts than people who simply think about unpleasant experiences.There is even some evidence that mind-wandering may be more of an antidote (缓解方法) to depression than a cause. People who are depressed may simply replay events from their past to better understand what happened to cause their dark mood and avoid future problems. Also, when researchers studied whether a negative mood preceded or allowed a mind-wandering episode, they found poor moods led to more mind-wandering but not vice versa. _____3_____Now, findings from a 2021 study suggest that mind-wandering that is more freely moving can actually improve your mood. In this study, participants were prompted randomly via cell phone over three days to report how they were feeling and how much their thoughts were freely moving and related to what they were doing. After analyzing the data, the researchers found that when people's thoughts were of-task, they generally felt more negative—similar to what earlier findings showed. _____4_____“Our findings suggest there might be positive aspects of mind-wandering," the researchers conclude.____5____ If I simply put myself in a space that lets my mind move freely, I don’t get depressed. On the contrary, I'm happier because of it.A. In some cases, people intentionally mind-wander.B. Mind-wandering is part of our human inheritance.C. Again, I find that science supports my own experience.D. There may be a right and a wrong way to mind-wander.E. But if their thoughts were free-moving, it had the opposite effect.F. In fact, the content of wandering thoughts makes a big difference.G. It suggests that mind-wandering may be helping people feel better.三、完形填空Growing up, the relationship between my father and I is that I asked him questions and he told me the answers.

A. survive B. exist C. last D. live2. A. work B. fix C. store D. purchase3. A. consequently B. gradually C. actually D. frequently4. A. gained B. requested C. lacked D. grasped5.

A. though B. while C. unless D. if10. A. nearly B. exactly C. originally D. merely11. A. apartment B. garden C. cabin D. house12. A. nothing B. something C. everything D. anything13. A. constructed B. suggested C. caught D. taught14. A. ever B. never C. hardly D. almost15. A. but B. and C. or D. so四、语法填空A)As a general rule, all forms of activity lead to boredom when they are performed _____1_____ a routine basis.

Bonham. One day, he watched a man who was blind ___3___ (attempt) to cross a street. The man’s cane was black and motorists couldn’t see it, so Bonham proposed painting the cane white with a red stripe to make it more ___4___ (notice). The ideaquickly ___5___ (catch) on around the U.S., making the White Cane an important tool for blind people to move ___6___(safe).Today, there are about 17,000,000 people with visual impairment in China, over 8,000,000 of ___7___ are blind. It is important that people raise awareness of their ___8___ (exist) and help improve their living conditions.Modern White Canes are becoming more and more lightweight and high-tech, making it ___9___ (easy) for them to travel independently.

高一语文限时训练(十)
高一语文限时训练（十）（一）现代文阅读（二）现代文阅读II（本题共4小题，16分）阅读下面的文字，完成6～9题。
东南亚餐厅的歌手朱宏第一次听见他唱歌就是在这家东南亚风格的餐厅。
他坐在餐厅一角-那里并没有舞台-怀里抱着把吉他，悠悠地唱着歌。
然而在喧闹的餐厅里，谁在认真听呢？我注意到他并不是因为歌唱得有多好。
那会儿他正在唱老鹰乐队的《加州旅馆》，中式英语从音箱里发出来，像一粒粒炒黄豆击中我的耳膜。
我于是去找发出这个声音的人，看见他戴着眼镜，仍凑近了看乐谱，把一首好端端的歌唱得像醉汉骑车。
我以为可能是因为他不太熟悉这首歌，可是我错了，他可能根本就没有一首熟悉的歌。
偏偏，他还唱了一晚上的英文歌曲。
请他驻唱，不知道饭店老板是怎么想的。
但是那儿的饭菜太好吃了，我舍不得因为歌手的原因而抛弃它。
每次我来的时候他都在，似乎他是这家饭店里唯一的歌手。
时间一长，我也就习惯了，甚至产生了一个错觉-《加州旅馆》跑调的那几处本来就应该这样唱。
就这样，我听他唱歌听了将近五年。
在这件事上，我最佩服三个人：①一个是歌手，坚持跑调五年不变，难能可贵；另一个是饭店老板，容忍歌手五年，足见他胸怀有多宽广；最后一个是我自己，五年不离不弃，愣是树立起了新的音乐审美标准。
有一天朋友组了个饭局，我被拉去作陪。
大家都坐定后，我发现有个人很面熟，一时又想不起来在哪儿见过。
朋友介绍后我才恍然大悟：这个熟面孔居然是东南亚餐厅的歌手。
他姓卢，和他一起来的是东南亚餐厅的老板西西。
近距离打量，老卢略显沧桑；西西年轻，细皮嫩肉的。
正是晚间就餐高峰的时候，“东南亚”那边的歌手跑这儿跟我们一道吃饭来了，我真替那边的顾客感到遗憾。
老卢在餐桌上有些拘谨。
西西叫他放松点儿，想吃什么就吃什么。
西西见我在看他俩，尴尬地抬了一下手说：“没办法，我舅是个老实人。
”老卢是西西的舅舅，那自然就是我们的舅舅。
在餐桌上我们纷纷给舅舅敬酒，让他成了今天的核心人物。
吃完饭我们去歌厅唱歌，老卢执意要先回家，被我们拽住了。
限时训练参考答案
限时训练参考答案限时训练参考答案在现代社会中，时间成为了一种宝贵的资源。
我们总是不断地追求高效率和快速完成任务的能力。
为了应对这种需求，限时训练应运而生。
限时训练是一种通过在规定的时间内完成任务来提高工作效率和学习能力的方法。
在这篇文章中，我们将探讨限时训练的意义和一些参考答案。
限时训练的意义在于它可以帮助我们培养时间管理和压力应对能力。
在限时训练中，我们必须在规定的时间内完成任务，这迫使我们学会合理安排时间和高效利用时间。
这种训练不仅可以提高我们的工作效率，还可以培养我们的冷静和应对压力的能力。
当我们在紧迫的时间限制下工作时，我们需要保持冷静并集中注意力，这对我们的工作和学习都非常重要。
在进行限时训练时，我们需要有一些参考答案来帮助我们评估自己的表现。
这些参考答案可以是标准答案、模板或者是其他人的答案。
通过参考答案，我们可以了解到自己在时间管理、任务完成和问题解决等方面的表现如何。
同时，参考答案也可以帮助我们发现自己的不足之处，并进行针对性的改进。
然而，我们需要明确的是，参考答案只是一种参考，我们并不需要完全照搬，而是应该根据自己的实际情况进行调整和改进。
在限时训练中，我们可以运用参考答案的方法和思路，但是我们需要注意避免机械地套用答案。
每个人都有自己的思维方式和解决问题的方法，因此我们需要根据自己的特点和优势来进行答题。
参考答案只是给我们提供一种思路和方法的参考，而不是唯一的正确答案。
我们需要根据自己的理解和思考来进行创新和发展。
限时训练不仅可以应用于学习和工作，也可以应用于日常生活中的各个方面。
比如，我们可以设定一个时间限制来完成家务，这样不仅可以提高效率，还可以让我们有更多的时间去做其他喜欢的事情。
又比如，我们可以设定一个时间限制来锻炼身体，这样不仅可以提高身体素质，还可以节约时间。
限时训练可以应用于各个领域，它可以帮助我们更好地管理时间，提高效率。
综上所述，限时训练是一种提高工作效率和学习能力的方法。
