课时分层作业 二十一Module 6　Period 1　　Is there something strange high up in the world’s tallest mountains? If so, is it a big bear? Is it a monkey? Or is it a kind of man? No one knows. This mystery has puzzled the world for years. In 1887, a mountain climber found large footprints in the snow. They looked like the footprints of a very large man. But men don’t walk without shoes in the snow. In 1906, another climber saw more footprints. Far off, he saw a very large animal standing on two legs. As he watched, it ran very quickly. Fifteen years later, newspapers had new stories about the “something”. A mountain climber said he had seen the “snow man” walk slowly across the snow, far below him. He said it looked like a very large man. From then on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back pictures of large footprints. The pictures showed clearly that the Snowman walked on two legs. So it was not a bear or a monkey. Could it be an ape (猿) man? The mystery grew! And the mystery keeps growing. Someday we may find out just what it is that makes the large footprints. 【语篇概述】本文是一篇说明文, 讲述了在喜马拉雅山上, 人们发现了大脚印, 甚至还拍摄了照片, 但是到底是谁留下的脚印? 会是雪人吗? 这仍然是未解之谜。

It’s not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse’s tail, you might think“sea monkey”is a better name. Then there’s the sea horse’s pouch(育儿袋). “Sea kangaroo”might also be a good name for this fish. 　　Sea horses live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings. A sea horse remains in one place for hours at a time by winding its tail around a plant. It feeds on live food, such as small shrimp. For a fish that doesn’t move around much, the sea horse eats a lot—in just one day, a sea horse can eat 3, 000 shrimps! A sea horse keeps the same mate for its whole life, and it’s the male sea horse that gives birth to baby sea horses. How does this happen? Baby sea horses start out as eggs, which come from the female’s body. The male carries the eggs in its pouch for about three weeks until they hatch. Soon after the babies are born, the female gives her mate a new set of eggs. 　　Sadly, the number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and sold as aquarium fish. This really is not a good idea because most sea horses don’t live long in aquariums. The best place for a sea horse is the ocean. 【语篇概述】本文主要介绍了有关海马的知识, 包括海马名字的来历, 生活习性, 如何繁殖及数量越来越少的原因。
