【解析】
这是一篇说明文。本文介绍了位于澳大利亚东海岸的弗雷泽岛的美丽景观。它因其独特的自然环境而成为世界遗产；岛上有超过120公里的干净海滩，还有雨林、珍稀鸟类和动物；这里还有美丽的驾车路线。
【1】下一句提到“这里的沙比撒哈拉沙漠还多。”联系下文，A选项“它是世界上最大的沙岛。”切题。该选项中的it和下一句中的it都是指的Fraser Island。故选A项。
【2】上一句提到“在沙丘之间的山谷里有淡水湖。”承接上文，F选项“岛上有100多个这样干净的小湖泊。”符合语境。故选F项。
【3】下一句提到“你需要这种车，因为你必须在沙地上开车。”联系下文，G选项“要想看到岛上所有的美景，你可以租一辆四轮驱动的汽车。”符合上下文语境。下一句中的“this type of vehicle”指代的就是G选项中的“a four-wheel-drive vehicle”。故选G项。
【4】上一句提到“弗雷泽岛上没有公路。”，承接上文，B选项“你不得不沿着海边开车。”符合逻辑，两句是因果关系。故选B项。
【5】上一句提到“如果你打算过夜，你必须在帐篷里露营，因为岛上几乎没有地方可以住”，承接上文，E选项“只有360人住在那里，并且只有几家旅馆”用来进一步说明岛上几乎没有地方可以住的原因。故选E项。
七选五的解题技巧之一是根据上下文词汇来锁定线索。即：要关注空白前后的名词和动词，然后在选项中查找它们的近义词、反义词、同义词、同类词等。其次是一些专有名词，比如说数词、代词、时间、年代、地点/名称等。如第1小题，所填A选项中的“it”和下一句中的it都是指的Fraser Island。
