The sea looks very pretty when the sun is shining on it. It can be very rough when there is a strong wind. The sea is very big. It covers three quarters of the globe! The sea is also very deep in some places. There is one spot near the Philippines , where the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put in the sea at that place, there would still be 3 kilometers of water above it! What a deep place! In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are millions of tiny living things that float in the sea. Many fish live by eating them. The sea can be very cold. When the diver goes downwards, the sea becomes colder and colder. When the diver goes deeper, the water exerts greater pressure.1、There is one spot near the Philippines, where the sea is as deep as ( ).A、13 kilometersB、 9 kilometersC、 2 kilometersD、 11 kilometers2、There are millions of tiny living things that float in the sea, and( ).A、they live by eating fishB、they live by eating plantsC、they are good food for many fishD、they live by eating worms3、Which of the following statements is true?
