How scientists now overcome the challenges of the depth? 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 maintained? Complete the summary of the reading passage by filling each blank with a word or phrase given in the box below modern huge plants and animals three-quarters mysterious biodiversity closely connected discoveries Despite covering (1) three-quarters of the earth’s mysterious surface, the ocean has remained (2) to modern technology we have us until recently With (3) discoveries about the now made important (4) biodiversity (5) .of marine life We have learnt that whether tiny or (6) ,all the(7) huge plants and animals connected of the seaclosely are (8) • Prepare Speaking lesson How scientists now overcome the challenges of the depth? By using modern devices What percentage of the earth’s surface is covered by seas and oceans? 75% of the earth’s surface X Lucky number! What can submarines to help scientists know about the undersea world? They investigate the seabed and bring samples of the marine life back to the surface for further study :2 You’ve just lost half of your points! You are unlucky! What would happen if the sea biodiversity were not maintained? The marine life would be at stake if the sea biodiversity were not maintained What can we learn from the satellite photos? We can know a wide range of information, including water temperature, depth and the undersea populations What are the three groups of marine plants and animals? They are those that live on or depend on the bottom like the starfish, those that move independently of water currents and those that are carried along by the currents ... overcome the challenges of the depth?
