Why is the 30th parallel north mysterious
What are some unusual explanations for it
What are some possible scientific explanations
Along a special line of latitude, known as the 30th parallel north, lie numerous sites of ancient civilisations and impressive natural features.
Ancient civilisations appeared on the parallel, including Babylon , with its famous tower; Egypt, with its pyramids; China, with its Sanxingdui culture, etc. These civilisations appeared at a similar time, and all developed advanced bronze-making techniques. Were they part of a single super-civilisation, as some think
It`s argued that the 30th parallel north is a line of great natural energy, with frequent earthquakes and volcanic eruptions. This creates amazing natural features, including Mount Qomolangma, the Dead Sea, and rivers, such as the Nile, the Mississippi and the Yangtze. Lacking any concrete evidence, some even claim it was supernatural powers!
Scientists, however, dispute these theories. It`s more likely, they argue, that civilisations arose on the 30th parallel north because the climate there is generally warm and wet. Major tectonic plates meet at this latitude, causing earthquakes, which helped form the Himalayas. The rest, they say, is either coincidence or fantasy.

有人认为北纬30度是一条自然能量线，地震和火山喷发频繁。 这创造了令人惊叹的自然景观，包括珠穆朗玛峰、死海和尼罗河、密西西比河和长江等河流。 由于没有任何具体的证据，一些人甚至声称这是超自然的力量!
然而，科学家们对这些理论持怀疑态度。 他们认为，更有可能的是，文明起源于北纬30度，因为那里的气候普遍温暖湿润。 主要的构造板块在这个纬度交汇，引发地震，从而形成了喜马拉雅山脉。 其余的，他们说，要么是巧合，要么是幻想。

Now write your article. 现在写一写你的文章。
The Bermuda Triangle
Far below the surface of the North Atlantic Ocean, in a roughly triangular area known as the Bermuda Triangle, lie more than 50 shipwrecks and 20 plane wrecks. What makes these wrecks so mysterious is that the cause of their fate remains largely unknown – ships were abandoned without apparent reason, distress signals were never sent and aircraft were lost without trace.
Some believe that supernatural forces are responsible, while others④ put the accidents and disappearances down to coincidence. Scientific theories, meanwhile, include pilot error when trying to navigate the area, and huge “rogue waves” caused by terrible storms.
Although many ships and planes cross the Bermuda Triangle without incident, the stories behind those doomed vessels’ fates continue to ⑤capture people’s imaginations.
参考范文
百慕大三角
在北大西洋深处，一个大致呈三角形的区域被称为百慕大三角，有50多艘船只残骸和20多架飞机残骸。 这些残骸之所以如此神秘，是因为它们的命运在很大程度上仍是未知的---船只在没有明显原因的情况下被遗弃，遇险信号从未发出，飞机也失去了踪迹。
一些人认为超自然力量是罪魁祸首，而另一些人则认为这些事故和失踪都是巧合。 与此同时，科学理论包括飞行员在试图航行时出现失误，以及可怕的风暴造成的巨大“异常涌浪”。
虽然许多船只和飞机都安然无恙地穿过百慕大三角，但这些遇难船只背后的故事仍在不断激发人们的想象力。
参考译文
④put ... down to coincidence
At first their mother put it down to coincidence: one of her twins was performing tasks with her right hand, the other using her left. 最初，看到自己的双胞胎女儿一个惯用左手而另一个惯用右手，她们的母亲以为这只是巧合。
Such a dichotomy cannot simply be attributed to coincidence.
这样一种分歧不能简单归之于巧合。
Don't you think it's getting kind of old to keep chalking everything up to coincidence
难道你们不觉得把这一切都归结为巧合有点不合时宜吗？
But now it is time to transform all of that into positive results, knowing that to win or lose is not down to coincidence. 但现在是时候将这一切转换成胜果的时候了。

____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Proust's perspective on exploration is profoundly insightful. He suggests that true discovery isn't about physically traveling to new places but about seeing the world through the eyes of others. This idea emphasizes empathy and the richness of diverse perspectives. By understanding how different people perceive the universe, we can experience a multitude of realities and deepen our own understanding of the world. This approach to exploration is both intellectual and emotional, highlighting the value of human connection and shared experiences.

My way to explore the world aligns with Proust's idea of gaining new perspectives. I believe in engaging deeply with different cultures, ideas, and people. For example, I enjoy reading literature from various countries and time periods. By immersing myself in the narratives and viewpoints of characters from different backgrounds, I gain insights into their lives and worldviews. This literary journey allows me to "possess other eyes" and see the universe through their experiences, enriching my understanding of the world without physically traveling.

What Exploration Means to Me
Good morning, everyone.
Today, I want to share what exploration means to me. Exploration isn’t just about traveling to new places; it’s about discovering new perspectives and ideas. For me, it’s a journey of the mind and heart.
First, exploration is about curiosity. It’s asking questions and seeking answers, whether through books, conversations, or experiences. Second, it’s about empathy. By understanding others’ views, we see the world through their eyes, enriching our own understanding.
For example, reading a novel from another culture can transport me to a different world, helping me see life from a new angle. This kind of exploration broadens my horizons without leaving my room.
In conclusion, exploration is about growth. It’s about stepping out of our comfort zones and embracing the unknown. Thank you.
Sample 1
What Exploration Means to Me
Hello everyone,
Today, I'd like to share with you what exploration means to me.
Firstly, exploration is not merely about discovering new geographical locations; it's a journey into new ideas, perspectives, and ways of thinking. It's about stepping out of our comfort zones and embracing the unknown.
Structurally, my speech will be divided into three parts: defining exploration, sharing personal experiences, and emphasizing its importance.
Personally, exploration has taken me places like Japan, where I faced a language barrier and cultural differences. Despite the challenges, I learned new things, tasted different foods, and even picked up some basic Japanese. These experiences enriched my life and broadened my horizons.
In conclusion, exploration is vital in life. It fosters growth, learning, and self-discovery. So, I urge you all to embrace exploration and see where it leads you.
Thank you for listening.

Dear Peter,
You wrote to ask about the Sanxingdui in China, now I’d like to give you a brief introduction.
Sanxingdui Ruins is the “Source of Yangtze of Civilization”, considered as one of the most important archaeological discoveries of the 20th century. On March 20, 2021, six new “sacrificial pits” were discovered, intriguing archaeologists.
The new cultural relics offer a window into the ancient Shu State. Notably, archaeologists have applied modern techniques to the excavation. The new discoveries have further expanded the world’s understanding of the Chinese civilization. Archaeologists will continue to throw themselves into delving into more unknown buried ruins.
Yours,
Li Hua

Good morning, everyone,
I’m Li Hua from Xing Guang Middle school. The topic of
my speech is “The unexplained --- the Loch Ness monster.”
In the north of Scotland there is a lake called Loch Ness. It’s
the deepest lake in the UK. People say a big monster lives in
the water. It weighs at least 1. 000 kilos.
People first told it over 500 years ago, but it became popular later. In 1993, it was said that some people saw a big monster in the middle of the lake. After that，some also said they saw a monster in Loch Ness. A few people took photos, but some of them weren’t real photos.Then scientists worked hard to find out the fact.
Is there really a monster in the lake There is no evidence that there is not. But one thing is true: plenty of people go there
for it evey year.
Thank you!

The Bermuda Triangle
Far below the surface of the North Atlantic Ocean, in a roughly triangular area known as the Bermuda Triangle, lie more than 50 shipwrecks and 20 plane wrecks. What makes these wrecks so mysterious is that the cause of their fate remains largely unknown – ships were abandoned without apparent reason, distress signals were never sent and aircraft were lost without trace.
Some believe that supernatural forces are responsible, while others④ put the accidents and disappearances down to coincidence. Scientific theories, meanwhile, include pilot error when trying to navigate the area, and huge “rogue waves” caused by terrible storms.
Although many ships and planes cross the Bermuda Triangle without incident, the stories behind those doomed vessels’ fates continue to ⑤capture people’s imaginations.
参考范文
百慕大三角
在北大西洋深处，一个大致呈三角形的区域被称为百慕大三角，有50多艘船只残骸和20多架飞机残骸。 这些残骸之所以如此神秘，是因为它们的命运在很大程度上仍是未知的---船只在没有明显原因的情况下被遗弃，遇险信号从未发出，飞机也失去了踪迹。
一些人认为超自然力量是罪魁祸首，而另一些人则认为这些事故和失踪都是巧合。 与此同时，科学理论包括飞行员在试图航行时出现失误，以及可怕的风暴造成的巨大“异常涌浪”。
虽然许多船只和飞机都安然无恙地穿过百慕大三角，但这些遇难船只背后的故事仍在不断激发人们的想象力。
参考译文
④put ... down to coincidence
At first their mother put it down to coincidence: one of her twins was performing tasks with her right hand, the other using her left. 最初，看到自己的双胞胎女儿一个惯用左手而另一个惯用右手，她们的母亲以为这只是巧合。
Such a dichotomy cannot simply be attributed to coincidence.
这样一种分歧不能简单归之于巧合。
Don't you think it's getting kind of old to keep chalking everything up to coincidence
难道你们不觉得把这一切都归结为巧合有点不合时宜吗？
But now it is time to transform all of that into positive results, knowing that to win or lose is not down to coincidence. 但现在是时候将这一切转换成胜果的时候了。

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Proust's perspective on exploration is profoundly insightful. He suggests that true discovery isn't about physically traveling to new places but about seeing the world through the eyes of others. This idea emphasizes empathy and the richness of diverse perspectives. By understanding how different people perceive the universe, we can experience a multitude of realities and deepen our own understanding of the world. This approach to exploration is both intellectual and emotional, highlighting the value of human connection and shared experiences.

My way to explore the world aligns with Proust's idea of gaining new perspectives. I believe in engaging deeply with different cultures, ideas, and people. For example, I enjoy reading literature from various countries and time periods. By immersing myself in the narratives and viewpoints of characters from different backgrounds, I gain insights into their lives and worldviews. This literary journey allows me to "possess other eyes" and see the universe through their experiences, enriching my understanding of the world without physically traveling.

What Exploration Means to Me
Good morning, everyone.
Today, I want to share what exploration means to me. Exploration isn’t just about traveling to new places; it’s about discovering new perspectives and ideas. For me, it’s a journey of the mind and heart.
First, exploration is about curiosity. It’s asking questions and seeking answers, whether through books, conversations, or experiences. Second, it’s about empathy. By understanding others’ views, we see the world through their eyes, enriching our own understanding.
For example, reading a novel from another culture can transport me to a different world, helping me see life from a new angle. This kind of exploration broadens my horizons without leaving my room.
In conclusion, exploration is about growth. It’s about stepping out of our comfort zones and embracing the unknown. Thank you.

What Exploration Means to Me
Hello everyone,
Today, I'd like to share with you what exploration means to me.
Firstly, exploration is not merely about discovering new geographical locations; it's a journey into new ideas, perspectives, and ways of thinking. It's about stepping out of our comfort zones and embracing the unknown.
Structurally, my speech will be divided into three parts: defining exploration, sharing personal experiences, and emphasizing its importance.
Personally, exploration has taken me places like Japan, where I faced a language barrier and cultural differences. Despite the challenges, I learned new things, tasted different foods, and even picked up some basic Japanese. These experiences enriched my life and broadened my horizons.
In conclusion, exploration is vital in life. It fosters growth, learning, and self-discovery. So, I urge you all to embrace exploration and see where it leads you.
Thank you for listening.

Dear Peter,
You wrote to ask about the Sanxingdui in China, now I’d like to give you a brief introduction.
Sanxingdui Ruins is the “Source of Yangtze of Civilization”, considered as one of the most important archaeological discoveries of the 20th century. On March 20, 2021, six new “sacrificial pits” were discovered, intriguing archaeologists.
The new cultural relics offer a window into the ancient Shu State. Notably, archaeologists have applied modern techniques to the excavation. The new discoveries have further expanded the world’s understanding of the Chinese civilization. Archaeologists will continue to throw themselves into delving into more unknown buried ruins.
Yours,
Li Hua
