What animal is it?Unit 9: Undersea WorldA: ReadingI.Pre-reading:	There is only one ocean. It’s divided into five different parts: the Pacific, Atlantic,Indian, Antartic, and Arctic Ocean. There are also many other smaller seas, gulf and bays which form part of them. Altogether they cover 75 percent of the earth’s surface. For centuries, people have challenged by the mysteries that lie beneath the ocean. However, today’s scientists have overcome many of the challenges ofthe 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 exit, 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 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. - Work in groups, guess the words hidden from the given pictures and information.- With a correct answer, your group will get 10 marks.GAME: CATCHING WORDS*gulf (n): vịnhThis is a large area of sea that is partly surrounded by land Things that scientists bring back from the seabed for further study.sample (n)This is a modern device which the scientists use to investigate the seabed.-> submarine (n) Oversized(a)Tiny (a) investigate (v) challenge (n/v) At stake = at riskBiodiversity(n)Water current (n) I.
