AThe undersea world is very beautiful． Now more and more people want to dive in the water to find the secrets there． Scuba diving is a new sport today． It can take you into a wonder-ful undersea world．You will find many strange animals in the sea． Some are as large as a school bus． Many sea animals give out light in the dark and some have sharp teeth．During the day， there is enough light． Here， under the sea， everything is blue and green．When fish swim nearby， you can catch them with your hands． When you have bottles of air on your back， you can stay in deep water for a long time． However， you can-t dive too deep． And you must be very careful when you dive in deep water．The deep sea is not an easy place to live in． It-s cold， and it，s dark， too． The deeper it is， the less sunlight there is． At about 3，000 feet， there is no light at all． It is very dark in the sea． Many fishes have no eyes． Some have big eyes． A few have eyes on one side． Besides the cold and the darkness， deep-sea animals face a third danger-other animals．Animals eat! They must find food to eat． Many animals eat plants． However， some am-mals eat meat． This means these sea animals have two big jobs． They need to find animals as food， and they have to try not to become other animals' meal．( )21． Why do people want to dive in the sea?

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?

Craig Rogers was sitting on his surfboard, scanning（审视）the distance for his next wave, when his board suddenly stopped moving._________(46)"I could have touched its eye with my elbow（肘部）,"says Craig. The shark had surfaced so quietly that he hadn't heard a thing.In his horror and confusion,he waved his arms and accidentally cut two of his fingers on the shark's teeth.He then slid off the opposite side of his surfboard into the water. Then,with Craig in the water and blood flowing from his fingers,the five-meter-long shark simply swam away,_______(47)Although sharks are often categorized as killers that hunt and eat as many humans as they can, this is actually inaccurate.Sharks very rarely kill humans.A person has a greater chance of being struck by lightning or drowning（淹死）in a bath than of being killed by a shark. Only 74 people have been reported killed by great whites in the last century.But great white sharks can reach six meters in length and weigh 2,200 kilograms or more.With frightening jaws that can hold up to3,000 teeth arranged in several rows,they could very easily kill and eat a helpless human in the water.________(48)Shark researchers are trying to comprehend the reasons that allow people to escape without being eaten.The most common explanation is that great whites don't see well._________(49)There is reason to doubt this,however. Recent information shows that great whites can actually see very well. Also,when attacking seals,great whites shoot up to the surface and bite with great force.When approaching humans,however,_________(50)They soon discover that humans are not a high一fat meal."They spit us out because we're too bony,"says Aidan Martin,director of Reef Quest Center for Shark Research.Shark researchers like Martin hypothesize that great whites are actually curious animals that like to investigate things.It's possible that they use their bite not only to kill and eat,but also to gather information.Although such an experience is unlucky for people like Craig Rogers,when sharks bite surfboards or other objects or people,they are likely just trying to learn what they are._________（50）A:disappearing into the water below.B:Why is it,then,that most people survive attacks by great whites?C:they most often move in slowly and bite less hard.D:There is reason to doubt that great whites see well enough to attack humans.E:It has been thought that they mistake people for the seals or sea lions which make up a large part of their diet.F:He looked down and was terrified to see a great white shark biting the front of his board.
