62．E 首句告诉我们“Anywhere that has a coastline with big waves is home to surfers.”，后部分告诉我们冲浪者来自澳大利亚和夏威夷，还有的来自加利福尼亚州、新西兰、英国。由此可以看出： Where surfers come from是本部分的主旨。
63．A “Get a board”“ …also have to be a very strong swimmer”是A项所说的“Preparations for surfing”的具体解释。
64．D 该部分告诉我们：Waves vary in size during different seasons and even at different times of the day，所以选择合适的海浪格外重要。
65．B 该部分首句中的“dangerous” 对应B项的“dangers”。该部分向我们介绍了冲浪潜在的危险：their own board or other surfers’ boards，great white sharks, stingrays and deadly jellyfish。
