四、閱讀測驗【請在下列各題中選出最適當的答案】 According to some authoritative anthropological studies in the last five decades, life expectancy of human beings was short for millennia. The few people who grew old were assumed, because of their years, to have won the favor of the gods. The typical person was fortunate to reach 40. Beginning in the 19th century, that slowly changed. Since 1840, life expectancy at birth has risen about three months with each passing year. In 1840, life expectancy at birth in Sweden, a much-studied nation owing to its record-keeping, was 45 years for women; today it’s 83 years. The United States displays roughly the same trend. When the 20th century began, life expectancy at birth in America was 47 years; now newborns are expected to live 79 years. If about three months continue to be added with each passing year, by the middle of this century, American life expectancy at birth will be 88 years. By the end of the century, it will be 100 years. Viewed globally, the lengthening of life spans seems independent of any single, specific event. It didn’t accelerate much as antibiotics and vaccines became common. Nor did it retreat much during wars or disease outbreaks. A graph of global life expectancy over time looks like an escalator rising smoothly. The trend holds, in most years, in individual nations rich and poor; the whole world is riding the escalator. Projections of ever-longer life spans assume no incredible medical discoveries—rather, that the escalator ride simply continues. If anti-aging drugs or genetic therapies are found, the climb could accelerate. Centenarians may become the norm, rather than rarities who generate a headline in the local newspaper.

根據過去五十年中一些權威的人類學研究，人類的預期壽命數千年來都十分短暫。由於年齡的原因，少數長壽的人們被認為贏得了眾神的青睞。典型的人幸運地達到了40歲。

從19世紀開始，這種情況逐漸改變。自1840年以來，出生時的預期壽命逐年增加了大約三個月。
1840年，瑞典由於受到記錄的保存，其出生時的預期壽命是女性45歲；到現在已經83歲了。

美國顯示出大致相同的趨勢。20世紀初，美國出生時的預期壽命為47歲。現在，新生兒有望活到79歲。如果繼續每年增加大約三個月的時間，那麼到本世紀中葉，美國人的預期壽命將為88歲。到本世紀末，將是100年。
