1. What different zones are there in the ocean
2. Which parts of the ocean do you think have been
explored
The different zones in the ocean are Sunlight Zone, Twilight Zone, Midnight Zone and Abyssal Zone.

Sunlight Zone, Twilight Zone.
Work in groups. Look at the picture and answer the questions. Do further research if necessary.
Pre-reading
3. What do you know about the deepest part of the ocean
The deepest part of the ocean is Abyssal Zone. It is an area where the water depth is about 2,000–5,000 metres. The trench can be lowered to 6,000 metres. These very deep areas are sometimes called “Super-abyssal zones”.
Actually it is the largest ecological region on earth.
Work in groups. Look at the picture and answer the questions. Do further research if necessary.

More than 500 years after it was lost in a storm, the Esmeralda was discovered off the coast of Oman. The ship is believed to be part of a voyage led by Portuguese explorer, Vasco da Gama during his second voyage to India (1502–1503).

Although the Esmeralda was first located in 1998, it was explored by marine archaeologists between 2013 and 2015. Researchers used advanced technology to examine some of the objects on the ship. For example, CT scanning was used to identify two silver coins and a bell.

The Jiaolong, China’s manned deep-sea vessel, is named after a mythical
Chinese sea dragon. At roughly 8.2 metres long, 3 metres wide and 3.4
metres high, it weighs almost 22 metric tons. In 2012, it set the record for the deepest dive after reaching

Read the passage and find out what has been discovered in the ocean depths.
Fast reading
Shipwrecks such as that of the Esmeralda, ruins of ancient cities like Neapolis, extraordinary deep-sea creatures such as bone-white coral and the barreleye, and the substance known as “fire ice” have been discovered in the ocean depths.
What has been discovered in the ocean depths
Fast reading
Shipwrecks such as that of the Esmeralda.
What has been discovered in the ocean depths
Evidence:
Para 1: Among these is the Esmeralda, the earliest
wreck from the age of the European exploration of
Asia.
Read the passage and find out what has been discovered in the ocean depths.
Fast reading
Ruins of ancient cities like Neapolis.
Evidence:
Para 2: One such find is the ancient Roman city of
Neapolis, discovered off the coast of Tunisia. Believed
to have been buried underwater by a tsunami in the
fourth century AD, the ruins of Neapolis are almost
2,000 years old.
Read the passage and find out what has been discovered in the ocean depths.
Fast reading
Extraordinary deep-sea creatures such as bone-white coral and the barreleye.
Evidence: Para 3: Imagine bone-white coral 6,000 metres below the ocean’s surface, growing at the rare of only one or two millimetres per year. Swimming through these black depths is the barreleye, a strange fish with eyes that can look upwards through its transparent forehead.
Read the passage and find out what has been discovered in the ocean depths.
Fast reading
The substance known as “fire ice”.
Evidence:
Para 4: Most notable of these is China’s discovery
of an ice-like substance, known as “fire ice”, under the South China Sea.

1. Why do you think the author uses statistics in the passage
Intensive reading
The use of statistics makes the passage more convincing.
Intensive reading
2. What other examples of ocean exploration do you know of Share one with the class.
One possible answer: ①On 10 October, 2020, Endeavour successfully completed 13 dives in Mariana Trench, eight of which broke 10,000 metres. ②There is a growing interest in the construction of a network of undersea observatories, which is the most effective means of early warning earthquake and tsunami.
3. What do you think drives the exploration of the oceans
One possible answer: The oceans make up 70% of the earth’s total area. Large numbers of marine animals and plants are important sources of food for human beings. Therefore, it is very important for us to understand the world’s oceans. In addition to concerns about maritime security and economic interests, exploration of the seabed will satisfy human’s curiosity and thirst for the unknown knowledge.
Intensive reading
4. What common message do the two reading passages in this unit convey How do they each build upon this idea
Intensive reading
Both passages convey the message that humans have the desire and means to explore the unknown. The first passage does this by looking at our fascination with history’s greatest mysteries, while the second passage looks at pioneering exploration of Earth’s oceans.
