参考答案：

【详解】考查动词短语和虚拟语气。句意：——你想步行去还是坐公共汽车去?——我想步行去，但因为没有时间了，我宁愿我们坐出租车去。feel like doing sth.为固定用法，表示想做某事；would rather (that)从句中用虚拟语气，对现在的假设用一般过去时，故选B。
2．B
【详解】考查动词的时态语态以及虚拟。句意：我本来想给你买一份贵重的生日礼物，但我把钱花光了。分析句子可知，第一空是在过去虚拟条件“如果我的钱没有花完”下，得出的结论，故需要用到would like to   have done表示“本想……但没有”。主语I和动词短语run out of为主谓关系，故用主动形式即可。故选B项。
3．B
【详解】考查非谓语动词、虚拟语气。句意：我建议把谈及的那个人关进监狱。主句中的谓语动词为suggest，意为“建议”，后接的宾语从句中用虚拟语气，谓语动词应用(should) do结构；从句中主语为the person，谓语动词put与主语the person之间为动宾关系，应用被动语态，故用（should）be put；动词refer to与逻辑主语the person之间为动宾关系，应用过去分词短语referred to，作后置定语，设空处应填referred to (should) be。故选B项。
4．D
