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.
Which of the following terms is EXCLUDED from the scientists’ Demographic Research?
选项 A、Statistics of births
B、Statistics of death
C、Statistics of diseases
D、Statistics of breast - feeding
答案D
解析 这是一道判断是非的题型。首先分析题干：“以下哪个术语不属于科学家的人口统计研究范畴?”。注意，是不属于。在文章倒数第二句话中“The study focused on people born at the beginning of the 20th century，using death certificates and census data．”意思是：该研究将焦点对准20世纪初出生的人，以死亡证明和人口普查数据为参考。选项A和B中有提到出生统计学和死亡统计学，不选。而原文“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—born baby and could influence its life expectancy in old age．”意思是：“孕妇怀孕期间所吃的东西因季节而变化，一年之中不同时期流行的传染病也不一样，两者都会对新生儿的健康产生影响，并进而影响他们到老年时的平均寿命。”，因此可知，选项c也在科学家的研究范畴之内。所以答案是选项D。
