People have speculated for centuries about a future without work. Today is no different, with academics, writers, and activists once again 【C1】______ that technology is replacing human workers. Some imagine that the coming work-free world will be defined by 【C2】______ . A few wealthy people will own all the capital, and the masses will struggle in an impoverished wasteland. A different and not mutually exclusive 【C3】______ holds that the future will be a wasteland of a different sort, one 【C4】______ by purposelessness: Without jobs to give their lives 【C5】______ , people will simply become lazy and depressed. 【C6】______ today' s unemployed don't seem to be having a great time. One Gallup poll found that 20 percent of Americans who have been unemployed for at least a year report having depression, double the rate for 【C7】______ Americans. Also, some research suggests that the 【C8】______ for rising rates of mortality, mental-health problems, and addicting 【C9】______ poorly-educated middle-aged people is shortage of well-paid jobs. Perhaps this is why many 【C10】______ the agonizing dullness of a jobless future. But it doesn' t 【C11】______ follow from findings like these that a world without work would be filled with unease. Such visions are based on the 【C12】______ of being unemployed in a society built on the concept of employment. In the 【C13】______ of work, a society designed with other ends in mind could 【C14】______ strikingly different circumstances for the future of labor and leisure. Today, the 【C15】______ of work may be a bit overblown. "Many jobs are boring, degrading, unhealthy, and a waste of human potential, " says John Danaher, a lecturer at the National University of Ireland in Galway. These days, because leisure time is relatively 【C16】______ for most workers, people use their free time to counterbalance the intellectual and emotional 【C17】______ of their jobs. "When I come home from a hard day' s work, I often feel 【C18】______ ," Danaher says, adding, "In a world in which I don ' t have to work, I might feel rather different"—perhaps different enough to throw himself 【C19】______ a hobby or a passion project with the intensity usually reserved for 【C20】______ matters.

【正确答案】 A

【答案解析】此处考查名词词义。由also可知，空缺词所在句与前句是并列递进关系，前句提及失业导致抑郁(having depression)，指失业带来的不良影响，强调因果关系，因此后句中也应对应因果关系。后句中shortage of well-paid jobs“高薪工作短缺”应为rising rates of mortality“死亡率上升”、mental-health problems“心理健康问题”等的原因，选项中explanation“解释”符合因果逻辑关系。

【正确答案】 C

【答案解析】此处考查动词词组。leave behind“留下，丢弃”；make up“构成；弥补”；worry about“焦虑，担心”；set aside“留出；驳回；撤销”。本句意为“可能这也是为什么多数人______个没有工作的未来会烦恼与无聊”。本段主要论述没有工作所带来的负面影响，本句也提及了负面影响(agonizing dullness)，结合选项，worry about与上下文语义一致，意为“担心”。
