They are mammals.Whales can’t stay in the 1 (deep) of the sea all the time as fish do. They have to come up for air from time to time. They breathe through blowholes at the top of their heads. When their warm breath hits the much 2 (cold) air outside, it makes a cloud of mist 3 (call) a “spout (水柱)”. You can spot a whale by its spout.Fish can’t make sounds but whales can. They use sounds 4 (communicate) with each other.5 biggest whale of all is the blue whale. It is6 (absolute) huge. It can be 110 feet long and weigh more than 150 tons.

They seem to be able to think, understand, and learn things quickly. But are they smart like humans or more than cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are similar in some ways. How?Fact 1: Talk to meLike humans, every dolphin has its own “name”. The name is a special whistle. Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, “talk” to each other about a lot of things, such as their ages, their feelings, or finding food. And, like humans, dolphins use a system of sounds and body languages to communicate. But understanding their conversations is not easy for humans. No one speaks dolphin’s language yet, but some scientists are trying to learn.Fact 2: Let’s playDolphins are also social animals. They live in groups, and they often join others from different groups to play games and have fun—just like people. In fact, playing together is something only intelligent animals do.Fact 3: Fishermen’s helperDolphins and humans are similar in another way: both make plans to get something they want. In the seas of southern Brazil, for example, dolphins use an interesting strategy to get food. When fish are near a boat, dolphins show signs to the fishermen to put theirnets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins in doing so? They get to eat some of the fish.1. What does a dolphin often use as its “name”?A. A body language.B. A special whistle.C. Its feeling.D. Its age.2. Why do dolphins join others from different groups?A. To learn to “talk”.B. To meet their families.C. To play games.D. To find food.3. How do dolphins help fishermen catch fish?A. By playing with other fish.B. By following fishing boats.C. By leading the fish into the net.D. By showing signs to the fishermen.4. What is the passage mainly about?A. Dolphins are smarter than humans.B. Dolphins make friends with humans.C. Dolphins teach humans to speak their language.D. Dolphins and humans are similar in some ways.BAbout 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?Every part of our seas and oceans contains an amazing number of animals that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic (微小的) animals, which are in turn consumed by larger animals. These food chains are delicately balanced.The bad news about the food chains in the oceans is that they are under threat because of man, People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats (海域). Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered (提倡) to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!5. Which of the following is the proper order of the food chain?A. S mall animals→algae→microscopic animals→large animals→man.B. A lgae→microscopic animals→large animals→larger animals→man.C. Small animals→algae→large animals→microscopic animals→man.D. M icroscopic animals→algae→large animals→larger animals→man.6. People used to think that the rubbish thrown into the sea____.A. wouldn’t harm the fish in the seaB. would change the balance of the food chainC. would be broken down in the seaD. wouldn’t do much harm to the sea7. From the passage, we learn that____.A. most fish and sea animals live at the surface of the seasB. it is very difficult to break the balance of a food chainC. excessive fishing has caused the decrease in fish stocksD. it won’t be long before the problems concerning oceans are solved8. Which of the following is NOT a way being used to protect the oceans?A. The use of international agreements.B. Forbidding fishing to protect fish stocks.C. The use of new techniques.D. Raising people’s awareness of protecting the oceans.2018-2019学年高二下学期训练卷选修七Unit3 Under the Sea英语（一）答案一、单句语法填空1. Being left2. urgent3. oppose4. accommodations5. sharply6.
