Lead-in
Look at the pictures and guess what it is for.
Watch the video and answer the questions.
Have you ever dived into the sea
What do you know about the sea world
Work in groups. Look at the picture and answer the questions. Do further research if necessary.
01
Epipelagic Zone - The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 metres (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light comes heat. This heat is responsible for the wide range of temperatures that occur in this zone.
Work in groups. Look at the picture and answer the questions. Do further research if necessary.
01
Mesopelagic Zone - Below the epipelagic zone is the mesopelagic zone, extending from 200 metres (656 feet) to 1,000 metres (3,281 feet). The mesopelagic zone is sometimes referred to as the twilight zone or the midwater zone. The light that penetrates to this depth is extremely faint. It is in this zone that we begin to see the twinkling lights of bioluminescent creatures. A great diversity of strange and bizarre fishes can be found here.
Work in groups. Look at the picture and answer the questions. Do further research if necessary.
01
Bthypelagic Zone - The next layer is called the bathypelagic zone. It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 metres (3,281 feet) down to 4,000 metres (13,124 feet). Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch. In spite of the pressure, a surprisingly large number of creatures can be found here. Sperm whales can dive down to this level in search of food. Most of the animals that live at these depths are black or red in color due to the lack of light.
Work in groups. Look at the picture and answer the questions. Do further research if necessary.
01
Abyssopelagic Zone - The next layer is called the abyssopelagic zone, also known as the abyssal zone or simply as the abyss. It extends from 4,000 metres (13,124 feet) to 6,000 metres (19,686 feet). The name comes from a Greek word meaning “no bottom”. The water temperature is near freezing, and there is no light at all. Very few creatures can be found at these crushing depths. Most of these are invertebrates such as basket stars and tiny squids. Three-quarters of the ocean floor lies within this zone. The deepest fish ever discovered was found in the Puerto Rico Trench (海沟) at a depth of 27,460 feet (8,372 metres).
Work in groups. Look at the picture and answer the questions. Do further research if necessary.

Learning to learn
Read the passage and find out what has been discovered in the ocean depths.
Lying under waters across the globe are an estimated three million shipwrecks. All of them represent attempts over the centuries to explore Earth’s furthest corners. Among these is the Esmeralda, the earliest wreck from the age of the European exploration of Asia. Today, some 500 years after the Esmeraldaset set sail, there is little – if any – land on our planet left unexplored. We have more detailed maps of the Moon, and even of Venus and Mars, than we do of Earth’s own sea bed.
DIVING DEEP
02
Read the passage and find out what has been discovered in the ocean depths.
Given our limited knowledge, it is perhaps no surprise that exploration of the oceans continues to lead to discoveries in various scientific fields. As with the discovery of the Esmeralda, many archaeological finds are made in shallow waters near the coast. These may sometimes include whole cities buried beneath the waves. One such find is the ancient Roman city of Neápolis, discovered off the coast of Tunisia. Believed to have been buried underwater by a tsunami in the fourth century AD, the ruins of Neápolis are almost 2,000 years old. The remaining streets and buildings offer a window into a fascinating period in our history. However, we are only beginning to overcome the challenges of pressure, darkness and extreme cold at vast depths. Fragments of the past lying deep beneath the oceans are still waiting to be discovered.
02
Read the passage and find out what has been discovered in the ocean depths.
Amazing biological discoveries are also being made. The dark zones of the oceans may contain up to 90 per cent of the planet’s fish. In these waters, more than 200 metres deep, where light cannot reach, are extraordinary creatures that appear as if they are straight out of science fiction. Imagine bone-white coral 6,000 metres below the ocean’s surface, growing at the rate of only one or two millimetres per year. Some of these could be 4,000 years old. Swimming through these black depths is the barreleye, a strange fish with eyes that can look upwards through its transparent forehead. In the very deepest ocean trenches that are more than 8,000 metres below the surface, the pressure is equivalent to 50 aeroplanes stacked one on top of another. Yet there is still life to be found, even around the deep-sea volcanic openings. These discoveries all help us understand the capacity for life on our planet, even in the most extreme circumstances.
02
Read the passage and find out what has been discovered in the ocean depths.
Furthermore, the oceans are a valuable source of natural resources, some of which are completely new to us. Most notable of these is China’s discovery of an ice-like substance, known as “fire ice”, under the South China Sea. In addition, China’s underwater vessels, such as the Jiaolong and Shenhai Yongshi, have been exploring waters at depths of thousands of metres. The Jiaolong even holds the record for the deepest dive by a manned submarine, at 7,062 metres, giving China its place alongside the world’s top ocean explorers. The research conducted by these vessels is giving scientists a greater understanding of how the sea bed was formed, as well as helping identify areas for deep-sea drilling, taking deep-sea exploration into a whole new era.
02
Read the passage and find out what has been discovered in the ocean depths.
Being a tough environment of complete darkness, enormous pressure and intense cold, the ocean depths have long been beyond the reach of human exploration. However, through closer international scientific, economic and cultural cooperation, we are all becoming part of a global mission to open up our planet’s final frontier. Humankind is entering a new age of oceanic discovery, and the world beneath the waves may one day be almost as familiar to us as the land we walk upon today.
02
Read the passage and find out what has been discovered in the ocean depths.

PART.04
Writing
Read the magazine article and answer the questions.

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 damp. 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 damp climate that made it a good place for civilisations to develop, and the fact that it is where major tectonic plates meet.
Plan an article about an unexplained phenomenon.
Do further research if necessary.

Now write your article.
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 others 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 capture people’s imaginations.

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 damp. Major tectonic plates meet at this latitude, causing earthquakes, which helped form the Himalayas. The rest, they say, is either coincidence or fantasy.

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 others 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 capture people’s imaginations.
