4. B

【分析】
本题考查疑问词+不定式的用法，需结合语境和语法规则逐一分析选项：首先，learn后可接“疑问词+不定式”作宾语，这是常见结构；其次，要判断选项的语义和语法是否正确：A选项语义不符，C选项语法错误，D选项形式错误，最终选出正确答案。
【解析】
1. 分析选项A：what to use意为“用什么”，代入句中“Mike正在学习用什么电脑”语义不通，排除；
2. 分析选项B：how to use是“疑问词+不定式”结构，意为“如何使用”，符合“学习使用电脑”的语境，语法正确；
3. 分析选项C：how he use中，主语he是第三人称单数，宾语从句谓语需用uses，语法错误，排除；
4. 分析选项D：how to using中，不定式符号to后需接动词原形，应为use，形式错误，排除。
综上，正确答案为B。
【答案】
B

非谓语动词（疑问词+不定式）、动词用法

本题考查基础的疑问词+不定式结构，需掌握该结构的正确形式及语义辨析，属于英语基础考点，难度较低。

5. C

【分析】
本题考查名词辨析和固定搭配的用法。首先分析第一个空，句子需要名词作主语，判断合适的名词形式；再分析第二个空，结合固定搭配确定正确的动词形式，逐步排除错误选项。
【解析】
1. 第一个空：句子结构为“The water ______ is very serious...”，此处需要名词作主语。pollute是动词（污染），pollution是名词（污染），因此第一空应填pollution，排除A选项。
2. 第二个空：固定搭配为“prevent sb (from) doing sth”，意为“阻止某人做某事”，其中from可省略，此处需用动名词形式，因此第二空填polluting，排除B、D选项。
综上，答案为C。
【答案】
C
【知识点】
名词辨析；固定搭配（prevent的用法）
【点评】
本题考查基础的名词形式和固定短语搭配，属于英语基础考点，需要学生掌握pollute的名词变形及prevent的常用搭配，难度较低。
