本题考查对英语句子表达正确性的判断，解题思路是依据常见的英语表达习惯和语法规则来分析每个选项。

• 选项A：“If you want to learn the language well, you should often put it into use.” 这句话中 “put...into use” 是一个常用的固定短语，意思是“把……投入使用”，该句子表达符合英语的表达习惯和语法规则，是正确的句子。
• 选项B：“If you want to learn the language well, you should often put use into it.” “put use into it” 这种表达不符合英语的习惯用法，正确的应该是 “put it into use”，所以该句子有误。
• 选项C：“use it into pudding” 这种表达不符合英语的逻辑和表达习惯，“use” 作为及物动词，一般直接接宾语，不需要 “into” 这个介词，所以该句子有误。
• 选项D：“If you want to learn the language well, you should often use it into put.” “use it into put” 这种表达混乱，不符合英语的语法和表达习惯，所以该句子有误。
