答案

1. carefully  2. useless        3. pollution   4. safety        5. second

解析

1.考查副词修饰动词。句意“为了不出现错误，约翰总是细心地做作业。”修饰动词does应该用副词，故填carefully。
2.考查固定句型和词形转换。句意“当你做错事的时候，寻找任何借口都是无用的。”It is+形容词 to do sth.，故填useless。
3.考查固定短语。句意“那家工厂生词一种新型的排放更少废气的汽车。”air pollution“空气污染”，动词pollute要变为名词。故填pollution。
4.考查形容词转换为名词。句意“所有的受害者都被救了出来并被带到安全地带。”形容词safe的名词形式是safety“安全；安全地”。to是介词，故填safety。
5.考查序数词。表示顺序应该用序数词。“我们都知道，母亲节在五月的第二个星期六。”故填second。
