Dolphins are not fish; they’re mammals. They are warm-blooded like man and give birth to one baby called a calf at a time. At birth a calf is about 90-130cm long and grows to about 4m. They live up to 40 years. They are highly sociable animals.
Their teeth are interlocking rows of hooks, suitable for holding slippery fish. They eat fish whole starting with head first. When they go wild they keep their mouth open and sometimes keep it nodding to express their aggression. Greater aggression is shown by violent jaw clapping. Dolphins breathe through their blowhole(呼吸孔) located at the top of their head. The dolphin’s eyes produce a special slippery secretion(分泌物) which protects the eyes from foreign objects and water friction.
Dolphins use their powerful tail to move through the water. They also use their tail while hunting. They slap their tail rapidly when they get annoyed or when they want to indicate the sign of danger to alert other dolphins.
The dolphin’s skin is completely smooth allowing the dolphin to move easily through the water, and also reduce heat loss. Their skin may bear rake marks from other dolphin’s teeth during play or mating, and can easily become badly sunburned if they strand(搁浅).
Their bodies are very streamlined so they may swim at high speed through the water, and an example of this is their ears. Dolphin’s ears are barely noticeable marked only by a small hole just behind the eyes.
While sleeping, it shuts down only half of its brain, as its breathing is under voluntary control. Dolphins take short catnaps, floating just below the surface, and then slowly rising to breathe. Often dolphins are very active during night time, for some this is their main feeding time. Dolphins are able to dive to great depths, and also leap to great heights. They may leap to avoid predators or to show how powerful they are to females at mating time.

Section B (10 marks)
Directions: Read the following passage, Answer the questions according to the
information given in the passage.
Have you ever thought about going from the Mississippi River to the Pacific Ocean, that is, from the east to the west of the USA? If you go by plane, you will make to trip in a few hours. If you go by train, you will finish the journey in two days. If you go by car, you will arrive there in a week or less. But how long does it take if you have to walk, or go on horseback or by boat? Certainly, it would take a lot more time if you do so.
But the first men to cross North America went this slow way. They went from St. Louis, Missouri, to the Pacific Ocean. They had to carry their own supplies with them. There were no roads to follow, and rivers were very dangerous.
Led by Meriwether Lewis and William Clark, a team of forty-five men left St. Louis on May 8, 1804. They traveled up the Mississippi River in boats. By late fall, the men reached the land of Manda Indians in what is now the state of North Dakota.Here they built a camp for the winter. Here they also met a French trapper(设陷阱捕兽者) and his Indian wife. The trapper and his wife became their guides later.
In the spring of the next year, the men started up the Mississippi River again. At last they came to a place where the river divided into three forks(支流). At this place there is now a small town called Three Forks, Montana.They followed one of the forks, the Jefferson River, but the river soon became too small and they could no longer use their boats. They walked many miles before they met some Indians. These Indians gave them horses for their trip over the Rocky Mountains.
The trip over the mountains was dangerous and difficult. Many of them were sick, and there was little food.On the west side of the mountains, they found the Columbia River. Here they built canoes(独木舟，小划子) to use on the rest of their trip to the west In November of 1806, after a long and hard trip, they reached the Pacific Ocean.
