龙源期刊网 “三个太阳”是怎么回事?作者:来源:《发明与创新(综合版)》2013年第01期2012年12月10日,上海、苏州和南通等地出现了“三个太阳”的天象。
天上并排的三个太阳在一条直线上,中间的那个太阳明亮,外围有一个大大的亮圆圈光环,另两个“太阳”轮廓不明显,位于明亮太阳左右两侧。
这种十分奇妙和壮观的天象使人联想到玛雅人“世界末日论”的预言:第五太阳纪始于公元前3113年,经过5125年的玛雅大周期,将在公元2012年12月22日前后结束,此后地球就要毁灭。
其实,“三个太阳”和玛雅预言毫无关联,是一种正常的天象,叫幻日弧光或环天顶弧,属于气象学的幻日现象,也是物理学中光的折射现象。
12月10日一大早,江苏南通市濠滨论坛上就有网友发帖称,早上看到了天空中同时出现3个太阳的“奇观”,并上传了图片。
一时间网友议论纷纷,甚至联想到了“玛雅预言”。
据了解,图片上的所谓3个太阳,是在刚刚升起的太阳两边,对称出现两个光点。
与此同时,12月10日上午在丹阳,也有网友拍到了两小一大三个“太阳”的奇景。
12月10日上午,上海、苏州和常州也出现了“3个太阳”。
常州网民“cinderella917”很幸运地用相机捕捉到了这极为罕见的天气现象,并将现场拍到的图片发送到了常州某知名论坛上,引来了部分网友的讨论:“太阳透过云洞射出的光?”“刚好两个像太阳一样的光点。
”有网友怀疑是不是拍摄者隔着玻璃拍摄的缘故,使原本正常的太阳出现了重影,不过拍摄者立即否认,并称自己并没有隔着玻璃进行拍摄。
有趣的是,由于时间接近流传甚广的“末日”谣言,有市民借此打趣:“2012真的来了哦!”不过,围观“母子太阳”的市民中不乏科学知识渊博者,有人就认为这应该是光线作用:“今早上我也注意到了,应该是云层反射。
”中国科学院南京紫金山天文台研究员王思潮指出,“三个太阳”是一种幻日现象,和世界末日没有任何关系。
如果云层太厚,我们就看不到“三个太阳”。

The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing (做针线活) or reading.After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”One bright morning I decided to clean my flat, including washing the window on the inside. Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, I can see the woman sitting by her window clearly. Her window was clean! Then I suddenly realized I had been criticizing (批评) her dirty window, but all the time I was watching hers through my own dirty window.That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings (缺点)?Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?” Then I try to clean the window of my own world so that I may see the world about me more clearly.34.What’s the relationship between the writer and the woman?A.They are friends.B.They are student and teacher.C.They are neighbors.D.They are doctor and patient.35.How did the writer know the woman’s window is dirty?A.Everything was unclear through the window.B.He went to the woman’s house to find.C.The woman was busy doing the housework.D.The writer knew the woman wasn’t at home.36.Which one is right according to the text?A.They lived in a small town.B.The writer often washed the window.C.They both worked as cleaners.D.The writer had never met the woman before. 37.What can we learn from the passage?A.One shouldn’t criticize others very often.B.One must judge himself before he judges others.C.One should often make his windows clean.D.One must look at others through his dirty windows.Some experts say that robots will take away human jobs with the rapid development of AI.A March 2023 report from Goldman Sachs showed that AI could do a quarter of the work done by humans. Across the European Union and the US, the report further notes that 300 million jobs could be lost to automation (自动化).Thankfully, it’s not all bad news. The experts also add that there are still things AI cannot do. These tasks have clear human qualities (特征), like emotional intelligence (情商) and creative thinking.“I think there are generally three kinds of jobs that are going to be safe,” says Martin Ford, writer of Rule of the Robots: How Artificial Intelligence Will Trans form Everything. “The first would be jobs that are creative enough to come up with new ideas and build something new.”The second is jobs that require complicated interpersonal relationships. Ford points to nurses, businessmen and reporters. “These are jobs,” he says, “where you need a very deep understanding of people. I think it’ll be a long time before AI has the ability to interact (交流) in the kinds of ways that really build relationships.”“The third safe one,” says Ford, “is jobs that really require lots of mobility (机动性) and dexterity (灵活性) and problem-solving ability in unpredictable environments. These are the kinds of jobs where you’re dealing with a new situation all the time, so they are probably the hardest of anything to automate.”“It’s important to note,” says Ford, “that a higher education or a high-paying position is not a protection against AI takeover. In short, looking for roles in changing environments that include unpredictable tasks is a good way to stop jobs from being taken by AI. At least, for a while.”38.What does the underlined phrase “These tasks” in Paragraph 2 refer to?A.The jobs AI cannot do.B.Some pieces of bad news.C.The jobs taken by AI.D.Some creative thinking jobs.39.Which of the following is a good way to stop human jobs from being replaced by AI?A.Getting a higher education.B.Repeating a task many times.C.Having a high-paying position.D.Dealing with various tasks well. 40.Which of the following statements is TRUE according to Martin Ford?A.AI can have a deep understanding of humans.B.Being a businessman is one of the hardest jobs.C.Jobs with creative thinking are less at risk of being replaced.D.Most of the work done by humans will be taken by AI soon.41.What is the main idea of the passage?A.Some good ways to get jobs.B.The jobs that won’t be taken by AI.C.Different opinions about jobs.D.The fight between AI and humans.Nils was a very naughty little boy. He went to school in winter, and looked after the farm animals when it was summer. He was very naughty. Sometimes he chased the swans and when he caught them, he pulled their feathers off. The swans were all very afraid of him.One day Nils was studying at home when suddenly he fell asleep. When he woke up, he saw in the mirror—a tiny Nils! He had become only a little thumb toy figure!But once he opened the door, he found all of swans circling around them. They chased him. They pinched (掐) him and laughed and said, “Now it is time for you to fear us!”Then the wild swans flew in and saw their ancestors and said, “Hey, come on! Let us all go to beautiful Switzerland!”A male swan named Max heard the wild swans, so he scooped up high into the sky. Nils found this good chance to experience new things, and held on tight to Max’s neck. They both flew high above into the sky. Nils was very scared, so he didn’t open his eyes at first. At last he got the courage to open his eyes and look down. He saw the white clouds high up the air, and saw the black earth under the ground.Max’s energy left him behind, so he fell behind the group. Max flapped his wings quickly and quickly, but he still felt down and down. Nils was very worried, so at first he said, “Don’t worry, Max. You rest for a while and let’s go home!” Max liked his comfort, so he quickly caught up with the group.The leader of the swans whose name was Oscar saw Nils and asked him, “Who are you?” Nils stood up and said: “My name is Nils. I was a human yesterday, but this morning…” Before Nils could finish his words, all the wild swans took a few steps back. Humans had been the swan’s enemy for centuries! No matter how hard Max tried to let Oscar agree to let Nils stay with them, Oscar still agreed to just let him stay with them for one night.When they all slept snugly that night, a fox crept out behind a tree. He had kept his eyes on the wild swans for a while, and still thought of their delicious meat even as they slept. Oscar sensed this and told all the swans to get up and fly away to a safer place.But Max left too quickly and dropped Nils down on the ground. Nils did not get hurt, but he did see the fox carrying the swan between his jaws. Nils shouted to him, “Hey, put the swan down!” He quickly grabbed the fox’s tail and pinched it with all his strength. This move allowed the fox to scream and so dropped the swan out of his mouth. Oscar said to Nils, “You are the first person to do good to a swan. So you can stay with us for the rest of the journey.”42.What happened to Nils after he woke up?A.He became a member of the swans.B.He lost his little thumb as a tiny boy.C.He had wings and joined the journey of the swans.D.He became smaller, the same size as a little thumb.43.Why did the swans say “Now it is time for you to fear us!” ?A.Because they were in groups and circling around Nils.B.Because they hated Nils and wanted to punish him now.C.Because they became brave and were not afraid of Nils any more.D.Because Nils was smaller than before and they could make fun of him now.44.In which order did swans change their feelings towards Nils?① Oscar thanked Nils for his kindness.① Max took Nils to the sky though tired.① Oscar thought of humans as the swans’ enemy.① Nils pulled swans’ feather off and made swans afraid.① Nils comforted Max and saved the swan from the fox.A.①①①①①B.①①①①①C.①①①①①D.①①①①①45.Which of the following word is NOT part of Nils’ personality according to this story?A.Naughty.B.Humorous.C.Kind.D.Curious.Raising Pets Is Good for Kids’ GrowthBringing a pet into a family with small children around is not a decision to make easily. Many parents are worried about the health and safety of the kids with pets around. 46 More ActiveKids with pets like dogs go outside more often for daily walks, exercise and have more playtime with them. A study shows that children with pets around are likely to move more. Other studies find similar results with disabled children and pets can help them to deal with the condition.More Sense of Responsibility47 Experts explained in an article how keeping a pet into a family with kids can teach the young responsibility. Pets require food, water and love. Taking care of a pet encourages children to learn the value of responsibility.More RelaxedStudies show that kids with pets are more relaxed. And they have less stress and have less to worry about. 48Better Reading AbilitiesKids who get pets often read to their pets. 49 They also find that reading to pets helps children make better connections between things and improve their reading motivation(动力). It means children can decide to do some reading on their own. 50Parents should practice safety tips for raising kids and pets together. This partnership can result in children growing up much healthier both mentally and physically.A.Researchers find their reading improves clearly.B.However, their worries turn out to be reasonable.C.Kids growing up with pets can be taught responsibility.D.Playing with pets can make kids calm down and happy.E.At the same time, their pets are probably good listeners.F.However, there are many advantages for kids growing up with them.G.This may be especially important for students who have problems in reading.四、单词拼写51.Every morning, many tourists (聚集) at Tian’ammen Square to watch the raising of the national flag.52.No matter how times change, the of Lei Feng will always be relevant. (精神) 53.Professor Li is (计划) to make a speech at tomorrow’s meeting.54.Success can only be a through hard work.55.Historic buildings all over the world are (有价值的) treasures for us.56.With the help of 5G technology, the apps on the smart phone can (提供) more functions for the users than before.57.—Sam, do you think watching short videos is just a w of time?—I think it depends on what kind of video you watch.58.Harry Potter Series have been very popular, both at home and (away from one’s own country).59.We should do what we can do to reduce pollution because it is (有害的) to the earth. 60.Could you help me (make something better) my speaking and writing?五、短文填空根据短文内容,用括号内所给词的正确时态或形式填空使短文完整。

每题只有一个选项最符合题意。
在挪威新奥尔松的北极黄河站(78°55′N,11°56′E),某北极科考团迎来极昼期第一天。
下图示意科考团当天拍摄并合成的太阳视运动轨迹(每间隔1小时拍摄一次)。
据此完成下面小题。
1. 科考团拍摄这一天日出照片时,太阳直射点位于()A. 23°26′N,11°56′EB. 11°05′N,11°56′EC. 11°05′N,168°04′WD. 11°05′S,168°04′W2. 当太阳位于图中Q位置时,某高中地理研学实践小组在北京市观察到太阳位于()A. 东北B. 西北C. 东南D. 西南【答案】1. C 2. D【解析】【1题详解】结合当地纬度,当地出现极昼现象时,太阳应直射11°05′N,排除AD。
极昼日出时,当地地方时为0点,结合当地经度11°56′E,计算可得此时地方时12点的地点位于168°04′W(太阳直射点所在的经线地方时为12点,两地经度相差180°),B错,C正确,故选C。
【2题详解】图中太阳最高时为当地12点,由于每隔1小时拍摄一次,所以太阳位于Q位置时,当地地方时为7点,当地经度为11°56′E,北京经度为116°E,所以此时北京地方时约为14点,已过正午但尚未日落,太阳位于当地的西南方天空,故选D。
【点睛】太阳直射哪个半球,则该半球的极地地区存在极昼现象,且出现极昼现象的最大范围的纬度与太阳直射的纬度的度数之和为90°。

三个太阳是什么现象
三个太阳是幻日现象,是大气的一种光学现象。
幻日是片状冰晶所形成的。
在天空中分布着大量微小的六角冰晶,在一定条件下,受日光照射就会发生折射现象。
幻日现象一般会出现在早晨五时三十分至六时之间或者上午九
时左右,傍晚也会出现。
但一般不会出现在正午,因为正午太阳直射,不满足折射的条件。
而且中午的太阳光线太强烈,即便有这个现象肉眼也不可能观测到。
出现幻日现象需要满足非常严苛的条件。
首先要有卷层云,有云才会形成冰晶其次云层要薄透光率要好,这样才能把太阳光折射出来。
还有很重要的一点就是太阳与冰晶以及观察者之间的角度要正好,稍微偏一点就看不到。
因此,“幻日”这种大气光学现象极为罕见。
由于太阳高度视角不同,冰晶的结构和疏密程度也不同,有菱形的、六角形的等,冰晶对太阳光的折射和反射就形成了各种颜色的“亮点”,其中最经典的就是环绕太阳的大晕圈,其他形状不标准的还有弧状和柱状的亮点,公众看起来觉得天空中像是有两个或三个太阳。
小学一年级作文题目《三个太阳》全文共6篇示例,供读者参考篇1【三个太阳】大家好,我是小明。
今天我想给大家讲一个很神奇的故事,这个故事发生在很久很久以前。
从前啊,有一个小村庄,住着很多很多勤劳的农民伯伯。
他们每天都要很早起床,去田里干活。
有一天清晨,小明伯伯睁开眼睛,看到窗外天色还暗暗的,他想:"咦?今天怎么太阳还没有出来呀?"于是他起了个大早,来到田里准备工作。
谁知,等小明伯伯来到田里时,发现天空中有三个太阳正在闪闪发亮!小明伯伯吓了一大跳,他从来没见过这种怪事。
三个太阳把整个村庄照得明亮亮的,就连小虫子都被晃花了眼睛。
小明伯伯连忙跑回家,把妻子和孩子们都叫了出来。
大家都被眼前的三个太阳给震惊住了。
"怎么回事啊?为什么会有三个太阳呢?"小明伯伯疑惑地说。
就在这时,一个老爷爷走了过来,他是小明伯伯的邻居。
老爷爷看到三个太阳也吓了一跳,但他机灵地说:"啊,我知道是怎么回事了!三个太阳代表着吉祥如意,村里一定会有好事发生哦!"大家听了老爷爷的话,都安心了不少。
他们决定今天去村里的庙宇里求个安全。
谁知,走到村口时,三个太阳突然合并成了一个太阳!大家看着这个骄阳似火的太阳,既害怕又惊奇。
第二天一早,小明伯伯一家人发现,天空中的太阳又恢复了正常。
大家都松了一口气,觉得昨天的怪事只是一个梦而已。
不过老村长听说了这件事后告诉大家,三个太阳其实是一种天文现象,叫做"假日"。
这是太阳光线被大气层折射形成的一种奇特景象,并不是真的有三个太阳。
从此以后,小明伯伯就等待着某一天,能亲眼目睹这种罕见的"假日"奇观。
虽然三个太阳看上去有些吓人,但它预示着吉祥和平安,让人向往。
这就是关于三个太阳的神奇故事了,你们喜欢吗?下次如果看到奇怪的天象,可别害怕哦,那说不定就是大自然在展现神奇的一面呢!篇2我们小朋友最喜欢听神奇有趣的故事了!我今天就给大家讲一个特别有意思的故事,叫《三个太阳》。
三日凌空原理
嘿,朋友!今天咱就来讲讲这超神奇的“三日凌空原理”。
你知道彩虹吧!那美丽的彩带挂在天空中,就好像是大自然给我们的礼物。
那“三日凌空”就像是天空给我们变的一个奇幻魔术!其实啊,三日凌空原理就是一种特殊的光学现象。
想象一下,在一个特定的条件下,比如说大气中的水汽呀、冰晶呀等等情况刚刚好,就像你做蛋糕时各种材料的比例恰到好处。
这时候,太阳光就会被这些水汽和冰晶折射和反射,哎呀呀,就好像是光在和我们玩捉迷藏!这不就有可能会出现三个太阳同时出现在天空中的神奇景象啦!就像你有时候在镜子前会看到好多个自己一样神奇呢!
你说这是不是超级有意思?这天空中一下子出现三个太阳,就像一下子多了两个小伙伴在陪着我们,那场面,哇塞,简直让人惊叹不已呀!如果有一天你真的看到了三日凌空,那可真是太幸运啦,你肯定会兴奋得跳起来,大喊着:“哇,这也太酷了吧!”
好啦,现在你对三日凌空原理是不是有点了解啦?是不是很想去亲眼看看这种神奇的现象呢?。

江苏等地惊现奇异天象:出现三个太阳【按】据网络报道,南通、常州、南京等地于2012年12月11日天空出现了两个太阳、三个太阳及“倒挂彩虹”等现象,这些都是所谓的幻日现象,和世界末日没有任何关系。
如果云层太厚,我们就看不到“三个太阳”。
南通上空昨出现“3个太阳”。
2012年12月11日,江苏的天空可谓是精彩纷呈。
在苏州、常州、南通、丹阳等地,不少市民看到天空出现了“两个太阳”甚至“3个太阳”;在南京,还有市民拍到了“倒挂的彩虹”。
记者了解到,类似的天象在上海也出现了。
专家表示,这些都是特殊的天象,和所谓的“末日”没有任何关系。
奇特天象1
天空出现“3个太阳”
发现地:上海、苏州、常州、南通、丹阳
南通市濠滨论坛上就有网友发帖称,早上看到了天空中同时出现3个太阳的“奇观”,并上传了图片。
一时间网友议论纷纷,甚至联想到了“玛雅预言”。
记者看到,图片上的所谓3个太阳,是在刚刚升起的太阳两边,对称出现两个光点。
昨天上午在丹阳,也有网友拍到了两小一大三个“太阳”的奇景。
上海、苏州和常州也出现了“3个太阳”。
常州网民“cinderella917”很幸运地用相机镜头捕捉到了这极为罕见的天气现象,并将现场拍到的图片发送到了常州某知名论坛上,引来了部分网友的讨论:“太阳透过云洞射出的光?”“刚好两个像太阳一样的光点。
”有网友怀疑是不是拍摄者隔着玻璃拍摄的缘故,使原本正常的太阳出现了重影,不过拍摄者立即否认,并称自己并没有隔着玻璃进行拍摄。
有趣的是,由于时间接近流传甚广的“末日”谣言,有市民借此打趣:“2012
真的来了哦!”不过,显然围观“母子太阳”的市民中不乏科学知识渊博者,有人就认为这应该是光线作用:“今早上我也注意到了,应该是云层反射。
”
常州幻日奇观。
专家释疑
“3个太阳”是“幻日”现象
高空薄云中许多冰晶体遇到太阳光会发生折射现象
中国科学院南京紫金山天文台研究员王思潮告诉记者,“三个太阳”是一种幻日现象,和世界末日没有任何关系。
如果云层太厚,我们就看不到“三个太阳”。
专家说,体型较小的“太阳”实际上是真太阳的幻影,这种特殊的大气现象较为罕见。
据介绍,“幻日”是大气的一种光学现象——在天空高层的半透明薄云里有许多六角形柱状的冰晶体,有时候它们会整整齐齐地垂直排列在空中,当太阳光射在这些六角形冰柱上就会发生非常规律的折射现象,折射到周围看起来就像出现了多个太阳。
通常,“幻日”持续的时间不会太长,短则几分钟,长则几十分钟。
它有时候会出现在早晨5时30分至6时或上午9时左右,有时候会出现在傍晚时分。
专家表示,出现“幻日”现象的条件其实较为苛刻。
首先,太阳光透过的必须是有冰晶的高空云层;其次,云层要薄,透光率要好。
最主要的是,太阳与冰晶以及观察者间的角度要正好,只要稍微偏差一点,就很难发现“幻日”奇景。

奇特天象2
晴天出现“倒挂彩虹”
发现地:南京
市民何先生像往常一样,冒着凛冽的寒风向单位走去。
在经过迈皋桥的沃尔玛超市时,他稍作休息伸了一个懒腰,没想到头一抬却瞥见个彩色的笑脸正挂在天空中,他惊讶地叫了起来,“看!彩虹!”他的叫声立刻引来了不少本来正埋头走路的行人,大家纷纷抬起头,讨论了起来。
“这天又没下雨,怎么一大早的出彩虹了?”他立刻掏出手机拍下了这幅美丽的画面,不过照片拍完之后他仔细一看又发现,“这彩虹怎么和往常的不一样,是一个反弧线”此时是早上9点10分了,阳光格外灿烂,一条倒挂的彩虹就这么毫无预兆的出现在天空的东北角,这也让何先生心情大好,将这张照片发上微博,这一奇景也让不少网友称奇。
南京上空昨现“倒挂彩虹”。
市民何先生供图
为什么在没下过雨的天空中会出现彩虹,又为什么是倒挂在天空中呢?记者请教了省气象台的专家,原来这种彩虹和冷空气有关。
在春秋季节,冷空气活动频繁,空气的温差较大,高空的气温较低,空气中的水蒸气在高空与冷空气相遇会出现结冰现象。
使得水蒸气的密度呈现倒置分布,即高处的密度反而比低处的密度大,出现了“倒三棱镜”的现象,也就是“倒彩虹”。
