B. How
C. How long

答案：1. C
解析：“than”是比较级的标志，“exciting”是多音节形容词，比较级是“more exciting”，故选C。
2. A
解析：“as...as...”中间用形容词原级，“sour”的原级是“sour”，故选A。
3. A
解析：“speak”是动词，用副词修饰，“well”是副词，“as well as”表示“和……一样好”，符合语境；“good”是形容词，不能修饰动词，所以B选项错误；C选项“as better as”结构错误；D选项“best than”结构错误，故选A。
4. C
解析：根据句意“电视太贵了。弗里斯一家不能……它。”，“afford”表示“买得起，负担得起”，符合语境；“pay”常与“for”搭配，“cost”的主语是物，“spend”常与“on sth./(in) doing sth.”搭配，均不符合，故选C。
5. D
解析：根据“cost”可知，问的是价格，“how much”表示“多少钱”，用于询问价格，故选D。
