B. How
C. How long

答案：1. C
解析：“than”是比較級的標志，“exciting”是多音節形容詞，比較級是“more exciting”，故選C。
2. A
解析：“as...as...”中間用形容詞原級，“sour”的原級是“sour”，故選A。
3. A
解析：“speak”是動詞，用副詞修飾，“well”是副詞，“as well as”表示“和……一樣好”，符合語境；“good”是形容詞，不能修飾動詞，所以B選項錯誤；C選項“as better as”結構錯誤；D選項“best than”結構錯誤，故選A。
4. C
解析：根據句意“電視太貴了。弗里斯一家不能……它。”，“afford”表示“買得起，負擔得起”，符合語境；“pay”常與“for”搭配，“cost”的主語是物，“spend”常與“on sth./(in) doing sth.”搭配，均不符合，故選C。
5. D
解析：根據“cost”可知，問的是價格，“how much”表示“多少錢”，用于詢問價格，故選D。
