要注意一些同义转换)，从而找出正确答案。跳读法即根据题干和选项所提供的信息跳读原文，并找到相关的句子(有时可能是几个句子)或段落，然后进行分析和推理等，从而找出正确答案。

以本文第1小题为例，本题运用定位法：我们根据题干Which of the following will probably make a fish ill?

其关键词是ill，从而直接定位到含有ill的同义词disease的句子--文中第二条建议Don't wipe the scales (鱼鳞) off the fish because it might cause it to develop a disease and reduce its chance of survival.可知，刮掉鱼鳞会让鱼生病，减少成活的机会。故B选项正确。

　　A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.

　　The child's mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. "Doctor," she said, "you have saved my little son. I don't know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it." The doctor stood up and said coldly, "Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done." The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, "Perhaps you will tell me how much your fee is?"

　　"Fifty pounds", he answered.

　　The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.
