(单选题)

The main aim in training for channel swimming is ______.

A.to be used to the water temperature in August

B.to learn to lengthen the practicing time each day

C.to be accustomed to being covered with grease as a protection

D.to be good at standing the long hours in cold water

参考答案：D

参考解析：

细节理解题。根据第二段第一句话“The main difficulty in training for channel swimming is becoming accustomed to the cold.”及下一句可知，训练的主要目标是适应寒冷的水温，A项意为“适应八月的水温”，根据首段可知，八月的水温是最高的，故排除；B项意为“延长每天的练习时间”，C项意为“习惯涂抹油脂作为保护”，这两项均为训练的项目而非目的；D项意为“擅长忍耐长时间待在冷水中”，根据语境，故选D。
