On which Ocean was the Titanic sunk? 5.This is the place where the penguins can live C I.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 GAME: CATCHING WORDS - Work in groups, guess the words hidden from the given pictures and information - With a correct answer, your group will get 10 marks This is a large area of sea that is partly surrounded by land *gulf (n): vịnh 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 risk Biodiversity(n) Water current (n) I Vocabulary: gulf (n) / gʌlf / : vịnh biển sample (n) ['sɑ:mpl] : mẫu vật oversized (a) ['ouvəsaiz] : to khổ tiny (a) ['taini] : nhỏ xíu investigate (v) [in'vestigeit]: điều tra , nghiên cứu challenge (n/v): ['t∫ælindʒ] thử thách biodiversity (n) : đa dạng sinh học submarine (n) [,sʌbmə'ri:n] : tàu ngầm water current(n) : dòng nước at stake = at risk : bị đe dọa II.While you read Task 1: fill each blank with one of the word given: gulf investigate oversized tiny biodiversity samples challenges provide tiny 1 Some plants and animals are referred to as …… organisms because they are extremely small 2 Thank to modern technology, scientists have investigate been able to …………………the life of plants and animals that live under the sea gulf 3 A………… is a large area of the sea that is partly surrounded by land 4 biodiversity ……………….is a term that refers to the existence of different kinds of animals and plants which make a balanced environment samples 5 These scientists have collected different ……………… to analyse for their experiment Task : answer the questions What percentage of the earth’s surface is covered by seas and oceans? How scientists now challenges of the depth? overcome the What can submarines to help scientists know about the undersea world? What can we learn from the satellite photos? What are the three groups of marine plants and animals? What would happen if the sea biodiversity were not maitained? III POST READING three-quarters of the Though covering ……… earth’s surface, the ocean has mysterious remained …………… to us until recently modern technology With ………… discoveries we have now made important ………… about the biodiversity ………… of marine life We have huge all learnt that whether tiny or ……, plants and animals of the sea are the ………… closely connected ………… ……… ... challenges of the depth? overcome the What can submarines to help scientists know about the undersea world? What can we learn from the satellite photos? What are the three groups of marine plants... 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...
