If you think life is wonderful and expect it to stay that way, then you may have a good chance of living to a ripe old age, at least that is what the findings of a new study suggest.

问答题
【C1】
【正确答案】B
【答案解析】空格前为to live to age 85 or，空格后为句点，连词or表示选择关系，由此可知，or后面可以填入名词或副词。文章首句提到，如果你认为生活是美好的，并期待它一直如此，那么你可能有很大的机会活到高龄，至少一项新研究的发现表明了这一点。这表明该研究的结果是乐观的人更有可能长寿，备选项中副词beyond表示“在……之后”，符合此处语境，即乐观程度最高的参与者更有可能活到85岁或以上，故选B。
【答案解析】空格前是情态动词could，空格后是名词短语the link，由此可知，空格处应填入一个动词原形，与could一起充当句子谓语。由后面的including whether participants had health conditions such as heart disease or cancer，or whether they experienced depression可知，此处是说影响长寿与乐观心态之间关系的因素，备选动词原形affect符合语境，故本题选A。
【答案解析】空格前是and a lower risk of，空格后是名词death，由此可知，空格处应填入一个形容词或分词。上文提及，先前的研究发现，更乐观的人患慢性病的风险更低，由并列连词and可知，此处应表示与“患慢性病”类似的消极信息，备选形容词premature意为“过早的”，代入文中表示更乐观的人过早死亡的风险也更低，符合语境，premature death为常用短语，意为“过早死亡”，故本题应选J。
问答题
【C6】
【正确答案】M
【答案解析】空格前为不定式标志词to，空格后为动词短语look at the relationship between…，由此可知，空格处应填入一个副词，修饰look at。上文提及，先前的研究发现，更乐观的人患慢性病的风险更低，过早死亡的风险也更低，本句开头的However意为“然而”，表示转折关系，故推知空格处应填入specifically，符合此处的语境，即“然而，这项新研究似乎是第一次专门研究乐观和长寿之间的关系”，故本题应选M。
【答案解析】空格前为情态动词may，空格后为名词短语good habits，由此可知，空格处应填入一个动词原形，与may一起充当句子谓语。整篇文章都在介绍一项有关乐观与长寿之间的关系的新研究，该研究对乐观持积极的态度，指出乐观的人更有可能长寿，乐观更有益于健康。由此可知，空格处应填入动词foster(培养)，foster good habits意为“培养好的习惯”，故本题应选E。
