提示说明：
先分析每词在句中的作用,例如:第3小题缺少修饰动词said的副词。第4小题需要考虑二步才能到位。
第1题：is 后面应该接形容词,将动词help+ ful构成形容词helpful。
第2题：该句应填修饰名词room的形容词,动词+ ing,构成其现在分词reading起形容词作用,作定语。
第3题：polite是形容词,此句缺少修饰动词said的副词politely。
第4题：careful是形容词,第一步先考虑该句需要修饰动词的副词carefully,第二步考虑句中的than提示你用比较级, more carefully 。
第5题：该句需要谓语动词,句中的语意告诉你是过去的事,用lost。

1）helpful 2）reading 3）politely 4）more carefully 5）lost
