　　It's comfortable _________ _________ ________ the couch and watch TV.

　　Harker Brayton was lying in a couch(长沙发). He smiled as he was reading a book. Suddenly he saw something in a dark corner of the room, under the bed. There, in the dark, two points of light were shining with green colour. His eyes couldn't move away from those shining points. Here right under the bed, he saw the body of a large snake(蛇). The points of light were its eyes! Brayton rose to his feet and got ready to back soft away from the snake. But at that moment, it was strange that he could not do so. He took a step forward(向前) instead, and then its eyes were still sticking up(竖起), and shining, with terrible light. After a moment, Brayton fell to the floor, unconscious(失去了知觉).

　　Two hours later, when the doctor was pulling the body out, he happened to look under the bed.“Good Heavens(天啊)!”he cried.“A snake!”he reached under the bed, pulled out the snake, and threw it to the middle of the room. It lay there without any movement. It was a snake made of cloth(布) and filled with cotton. Its eyes were two buttons(钮扣).
