A science book gives facts. Some science books tell us about animals. Some tell us about plants. Some tell us about outer space. This page tells us about animals.
Do you know that not only the fish but also some animals live in the sea? For example, the whale is not a fish. It can't breathe in the water. It swims in the water. But it comes up for air.
The blue whale is the world's biggest animal. There are other sea animals, too. One is called the dolphin. Dolphins need air to live. They breathe air, as whales do. Dolphins are very clever. They sometimes seem to speak to each other.
Many other animals live near the sea. Seals (海豹) and otters（水獭）love the sea. They swim and play there, They eat smaller fish and sea plants. Seals and otters have thick fur. The fur keeps them warm.
【小题1】The passage mainly tells us about _______.

He was 11 years old and went fishing every chance he got from the dock at his family's cabin on an island in the middle of a New Hampshire lake.

On the day before the bass season opened, he and his father were fishing early in the evening, catching sunfish and perch（鲈鱼）with worms. Then he tied on a small silver lure（鱼饵）and practiced casting. The lure struck the water and caused colored ripples in the sunset, then silver ripples as the moon rose over the lake.

?? When his pole doubled over, he knew something huge was on the other end. Finally, he very gingerly lifted the exhausted fish from the water. It was the largest one he had ever seen, but it was a perch . The boy and his father looked at the handsome fish. Then the father lit a match(火柴) and looked at his watch. It was 10 P.M.--- two hours before the season opened. He looked at the fish, then at the boy.

? "You'll have to put it back, son," he said.

? "Dad!" cried the boy.

? "There will be other fish," said his father.

? "Not as big as this one," cried the boy.

? He looked around the lake. No other fishermen or boats were anywhere around in the moonlight. He looked again at his father. Even though no one had seen them, nor could anyone ever know what time he caught the fish, the boy could know everything by his father's clear voice that the decision could not be changed. He slowly worked the hook(钩) out of the lip of the huge bass and lowered it into the black water.

?? The creature swished its powerful body and disappeared. The boy suspected that he would never again see such a great fish.

?? That was 34 years ago. Today, the boy is a successful architect in New York City. His father's cabin is still there on the island in the middle of the lake. He takes his own son and daughters fishing from the same dock.

?? He was right. He has never again caught such a magnificent fish as the one he landed that night long ago. But he does see that same fish---again and again---every time he comes up against a question of ethics（道德规范）.

Penguins are lovely animals. Most people like them. But now as many as 10 of the 17 kinds of penguins are in danger of disappearing. The number of penguins has decreased by ( 减少了) 30% since 1987.

Penguins are black and white birds that live in the southern part of the world. They are common in the Antarctic Continent (南极大陆) ,New Zealand, Australia and South America. Many live near cold waters (水域). But some live near warm waters in Galapagos Islands. Penguins  cannot fly, but  they are fine swimmers. The shape of their body helps them to survive. Penguins eat fish and krill  (磷虾). They have short wings that help them to dive up to 900 feet to catch larger fish. They can swim 10-15 kilometers an hour which lets them protect themselves. They also have lots of body oil that helps in keeping them dry in the water.

The warming of the earth is the reason for the decrease in the number of penguins. The hotter and hotter air has caused ocean waters to become warmer. Higher water temperature has decreased the fish and krill. Some years later these birds are completely unable to reproduce. And many adult penguins die of hunger.

Too much fishing, exploration for oil and oil leaks (泄漏) also make penguins be in danger. Poisonous things in ocean waters are another danger. Penguins also have their enemies, including sharks, seals and sea lions.

1.Penguins can do the following except________.

2.Which of the following is NOT the reason for the decrease in the number penguins?

3.What does the underlined word "reproduce" mean?

4. What's the passage mainly about?
