Unit 5 Into the unknown
Learning objective
To know the structure and characteristics of the passage writing about the unexplained
Along a special line of latitude, known as the 30th parallel north, lie numerous sites of ancient civilisations and impressive natural features.
n. 纬度
Read the magazine article and answer the questions.
Pre-writing
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
青铜制造技术
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!
具体的证据
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.

1. Why is the 30th parallel north mysterious
The 30th parallel north is mysterious because it is where numerous sites of ancient civilisations and impressive natural features lie.
2. What are some unusual explanations for it
Some believe that the 30th parallel north is a line of great natural energy, with frequent earthquakes and volcanic eruptions, and others even claim that its amazing natural features were caused by supernatural powers.
3. What are some possible scientific explanations
Possible scientific explanations for the 30th parallel north include the generally warm and wet climate that made it a good place for civilisations to develop, and the fact that it is where major tectonic plates meet.
What does an article about an unexplained phenomenon usually include

What is the unexplained phenomenon
Why is it mysterious
What non-scientific explanations are there
How do scientists explain it
What is the unexplained phenomenon
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.
Why is it mysterious
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.
What non-scientific explanations are there
Some believe that supernatural forces are responsible, while others put the accidents and disappearances down to coincidence.
How do scientists explain it
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 capture people’s imaginations.
Now write an article about an unexplained phenomenon.
Please keep in mind the four parts to be included in an article about an unexplained phenomenon.
Do further research if necessary.
Work in pairs. Make improvements to each other’s articles and share them with the class.
