38．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。
39．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。
40．D

44．C
【详解】考查虚拟语气。句意：爱好和平的人们的确认为利比亚的暴力冲突是时候该结束了。A. come to an end结束；B. put to an end使……结束；C. came to an end结束；D. bring to an end使……结束；根据虚拟语气的用法，“It is time that 句型”中的谓语动词要使用一般过去时形式，因此A项不正确，B 项put an end 的意思是“使……结束”，与句子表达的含义一致需使用被动语态。D 项put an end 的意思是“使……结束”，与句子表达的含义一致需使用被动语态。C 项came to an end 的含义是“结束”，与句子表达的含义一致，且符合虚拟语气的用法，故选C 项。
