问题     People born in autumn live longer than those born in spring and are less likely to fall chronically ill when they are older, according to an Austrian scientist, Using census (人口普查) data for more than one million people in Austrian. Denmark and Australia, scientists at the Max Plank Institute for Demographic (人口统计的) Research found the month of birth was related to life expectancy over the age of 50. Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new - bom baby and could influence its life expectancy in old age. " A mother giving birth in spring spends the last stage of her pregnancy in winter, when she will eat fewer vitamins than in summer. " said one of the scientists. " When she stops breast - feeding and starts giving her baby normal food, it’s in the hot weeks of summer when babies are inclined to infections of the digestive system. " In Austria, adults born in autumn lived about seven months longer than those born in spring, and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture is similar. A-dults born in the Australian autumn lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition at all times of the year has improved since then, the seasonal pattern persists.
People born in autumn live longer than those born in spring because________.
选项 A、a baby born in autumn is never subject to any infections
B、a baby born in spring receives no protection from infections
C、a mother giving birth in spring has less nutrition during her pregnancy
D、a mother giving birth in autumn eats more vitamins during the last stage of her pregnancy
答案D
解析 这是一道考察细节的题型，题干要求：秋季出生的人比春季出生的人长寿的原因。文章引用了一位科学家的观点“A mother giving birth in spring spends the last stage of her-pregnancy in winter，when she will eat fewer vitamins than in summer”意思是：春季分娩的母亲在冬天度过孕期的最后阶段，她在这个时间段摄入的维生素比夏季摄入的少。而秋季分娩的孕妇恰好在夏季度过孕期的最后阶段。由此可知，维生素摄入量的大小不同对新生儿的健康及其平均寿命都有影响，故正确选项是D。而文章中没有涉及到选项A，“秋季出生的婴儿不会感染任何传染病”。选项B，“春季出生的婴儿对传染病没有抵抗力”和选项C，“春季分娩的母亲怀孕期间摄人较少营养”。
