想法”，D项意为“关键，答案”，都与语境不符。42.A解析：根据该句中的“twentyfourhoursinthedayforeveryone”可知，每个人每天都有24小时，故用“therebe”结构，表示“存在，有”,介词about后跟名词、代词、动名词作宾语，故A项正确。43。B解析：根据语境可知，每个人每天都有24小时，所以“没有足够的时间”作为解释是不能接受的；B项意为“可接受的”，故B项正确.A项意为“奇怪的”;C项意为“令人惊讶的”；D项意为“要求高的，费力的".44。B解析：根据语境可知，每个人每天都有24小时,所以“没有足够的时间"不能解释没有完成工作。getsomethingdone为固定搭配，意为“完成某事”,该处表示否定,前面用not，故B项正确。45。D解析：根据该句中的“Itriedtoprovetooneofmyprofessors”，结合下文的“Hisanswertomewas”可知，该处叙述的是一件过去发生的事情，D项意为“曾经”，故D项正确。A项意为“从那时起”；B项意为“刚刚,刚才”；C项意为“曾经”。46.A解析：根据该句中的“sayingthatIwasworkinghard”可知，“我”试图通过说“我”自己工作勤奋来向“我”的一位教授证明自己；A项表示方式，故A项正确。47.B解析：分析该句结构可知,空处引导主语从句，也作该从句的主语，故用连接代词what;该句意“重要的是你的工作质量”，故B项正确.48。D解析:根据上文中的“Iwasworkinghard”，结合该句语境和第三段最后一句中的“quality"可知，教授对“工作勤奋”的回答是“重要的是工作质量
