1. 固定搭配choose to do sth意为“选择做某事”，volunteer as 是固定表达“自愿担任/作为”，符合学生假期做社区志愿者帮助老人的语境，填动词原形volunteer。
2. 固定结构It is a good habit to do sth意为“做某事是好习惯”，review what you have learned 表示“复习你所学过的内容”，符合考前的行为语境，填动词原形review。
3. 根据后半句的was可知句子时态为一般过去时，beat the dust out of the rug 表示“拍打地毯上的灰尘”，beat的过去式仍为beat。
4. 固定搭配begin to do sth意为“开始做某事”，wave at sb 是固定表达“向某人挥手”，符合语境，填动词原形wave。
5. 根据后半句的didn't listen可知句子时态为一般过去时，warn sb to do sth 表示“提醒/警告某人做某事”，warn的过去式为warned。

9. 情态动词will后接动词原形，interview sb about sth 表示“就某事采访某人”，符合记者的行为语境，填interview。
10. 此处需要形容词作表语，power的形容词形式powerful意为“有力量的”，符合“知识就是力量”的语境。
