3. of what life will be like in 100 years
4. of the low price of the house

本题考查用“介词+名词/动名词短语/宾语从句”的结构改写句子，需结合固定搭配和括号内词汇完成：
1. “be certain of”是固定搭配，原句表达地址将被更改，用动名词被动形式“the address being changed”，既符合语义又用到括号内的“change”；
2. “be sure of”是固定搭配，原句询问北京与南京的距离，用“the distance between Beijing and Nanjing”，用到括号内的“distance”；
3. “be aware of”是固定搭配，后可接宾语从句“what life will be like in 100 years”，用到括号内的“life”；
4. “be sure of”是固定搭配，原句表达房价低，用“the low price of the house”，用到括号内的“price”；
5. “agree about”是固定搭配，原句表达污水是小镇的问题，用“the polluted water being a problem in the small town”，用到括号内的“problem”。
