新概念英语第四册惯用语整理Lesson18

新概念第四册课文翻译及学习笔记：Lesson18【课文】First listen and then answer the following question.听录音，然后回答以下问题。

What would you say is the main characteristic of porpoises?There has long been a superstition among mariners that porpoises will save drowning men by pushing them to the surface, or protect them from sharks by surrounding them in defensive formation. Marine Studio biologists have pointed out that, however intelligent they may be, it is probably a mistake to credit dolphins with any motive of lifesaving. On the occasions when they have pushed to shore an unconscious human being they have much more likely done it out of curiosity or for sport, as in riding the bow waves of a ship. In 1928 some porpoises were photographed working like beavers to push ashore a waterlogged mattress. If, as has been reported, they have protected humans from sharks, it may have been because curiosity attracted them and because the scent of a possible meal attracted the sharks. Porpoises and sharks are natural enemies. It is possible that upon such an occasion a battle ensued, with the sharks being driven away or killed.Whether it be bird, fish or beast, the porpoise is intrigued with anything that is alive. They are constantly after the turtles, who peacefully submit to all sorts of indignities. One young calf especially enjoyed raising a turtle to the surface with his snout and then shoving him across the tank like an aquaplane. Almost any day a young porpoise may be seen trying to turn a 300-pound sea turtle over by sticking his snout under the edge of his shell and pushing up for dear life. This is not easy, and may require two porpoises working together. In another game, as the turtle swims across the oceanarium, the first porpoise swoops down from above and butts his shell with his belly. This knocks the turtle down several feet. He no sooner recovers his equilibrium than the next porpoise comes along and hits him another crack. Eventually the turtle has been butted all the way down to the floor of the tank. He is now satisfied merely to try to stand up, but as soon as he does so a porpoise knocks him flat. The turtle at last gives up by pulling his feet under his shell and the game is over.RALPH NADING HILL Window in the Sea【New words and expressions 生词和短语】porpoise n. 海豚mariner n. 水手shark n. 鲨鱼formation n. 队形dolphin n. 海豚科动物unconscious adj. 不省人事beaver n. 海狸ashore adv. 上岸waterlogged adj. 浸满水的scent n. 香味ensue v. 接着发生intrigue v. 引起兴趣indignity n. 侮辱snout n. 口鼻部shove v. 硬推aquaplane n. 驾浪滑水板oceanarium n. 水族馆swoop v. 猛扑belly n. 腹部equilibrium n. 平衡butt v. 碰撞crack n. 重击【课文注释】1.however intelligent they may be，不管它们有多聪明，这是一个让步状语从句，相当于no matter how intelligent they may be。

L1 Finding fossil manWe can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only way that they can preserve their history is to recount it assagas----legends handeddown from one generation of storytellers to another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago.But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first'modern men' came from.Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. Stone does not decay, and so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace.New words and expressionsrecount /ri'kaunt/ v.叙述/ ' rei'kaunt/ 再数一次record / ' rek[d/ /ri' kC:d/ 第一个音节带重音，名前动后叙述：recount : emotionless 重复describedepict：a little emotionalnarrate：temporal&spacial 根据时间或空间顺序描述。
