点睛：六选五题型，给出一篇缺少5个句子的文章，对应有六个选项，要求同学们根据文章结构、内容，选出正确的句子，填入相应的空白处。“主要考查考生对文章的整体内容和结构以及上下文逻辑意义的理解和掌握。从该题型给出的选项中我们可以发现一些特点：该题型选项大致可分为主旨概括句（文章整体内容）、过渡性句子（文章结构）和注释性句子（上下文逻辑意义）三类。另外两个多余的干扰项也可以通过这三个特点来排除，例如主旨概括句要么过于宽泛要么以偏概全或偏离主题，过渡性句子不能反映文章的行文结构，注释性句子与上文脱节等。做这种题时，1、先看选项。我们可以通过句子的完整性或者句子后面的标点符号来判断该句在文章中的位置。我们可以看出C和D是概括性语言，应是段落开头。A，E，F是结论，应是句文中。B选项好像与其他选项没关系，可以排除。再看空前空后。2。由于六选五空出的是整个句子，而这些句子与句子之间，必然有一种联系，因此我们可以通过选项中某个名词或动词跟空前或空后的一致性或者相关性来确定这两个句子之间有一种关联性，从而选择正确的答案。例如，本文第1题。根据下文内容In fact, it is the largest sand island in the world. （事实上，它是世界上最大的沙岛。）结合句意和语境可知选C（The island is completely made of sand这个岛完全是用沙子建造的。）。
