解析
【分析】
先观察题目给出的例句，前3句的动词ask、allow、tell属于普通动词，它们的宾语补足语用动词不定式时，不定式符号to保留；后3句的let、have、make是使役动词，help是特殊动词，其中使役动词的宾语补足语不定式符号to要省略，help的不定式符号to可省可不省。结合规则探究的问题，第1题对应普通动词的情况，第2题对应使役动词的情况，即可得出答案。
【解析】
1. 动词ask、allow、tell等普通动词后接动词不定式作宾语补足语时，不定式符号to不能省略，因此填“不可以”；
2. 使役动词let、have、make等后接动词不定式作宾语补足语时，不定式符号to必须省略，因此填“省略”。
【答案】
1. 不可以 2. 省略
