Units 9 Undersea world –

Work with a partner. Look at the map and give the Vietnamese names for the oceans on the map. Can you name the sea animal in each picture? The first letter of the word has been given to help you. While you read Read the text and do the tasks that follow. There is only one ocean. It is divided into five different parts: the Pacific, Atlantic, Indian, Antarctic, and Arctic Oceans. There are also many other smaller seas, gulfs and bays which form part of them. Altogether they cover 75 percent of the earth’s surface. For centuries, people have been challenged by the mysteries that lie beneath the ocean. However, today’s scientists have overcome many of the challenges of the depth by using modern devices. They send submarines to investigate the seabed and bring samples of marine life back to the surface for further study. Satellite photographs provide a wide range of information, including water temperature, depth and the undersea populations. If modern technology did not exist, we would never have such precious information. Marine plants and animals fall into three major groups. Some of them live on or depend on the bottom like the starfish. Some are swimming animals such as fishes and sharks that move independently of water currents while others are tiny organisms that are carried along by the currents like the jellyfish. Plants and animals of the sea, however small or oversized, all contribute to its biodiversity. Unless this biodiversity were maintained, marine life would be at stake.D3 Task 1.

Work in pairs. Read the description of the sperm whale and then complete the table that follows. Sperm whales are the biggest animals on Earth that have teeth. They are carnivores, which means they eat meat. Although sperm whales can be found in all oceans, they prefer the waters with high squid populations, which are their main diet. A sperm whale can eat up to 1,500 kg of food each day. Sperm whales are big animals. The males can grow up to 18 metres long and weigh up to 54,000 kg while the females are a bit smaller with a length of 12 metres and a weight of 17,000 kg. A female sperm whale gives birth to one calf every five to seven years after a gestation period of fourteen to nineteen months. The life span of sperm whales can be up to sixty or seventy years. It is interesting to know that they also have the largest brain of any mammals. Sperm whale populations are at risk due to hunting and their accidental entrapment in fishing nets.
