Question

Have you thanked your grandma today? You might want to consider it. A recent study found that kids live longer when a grandmother takes part in their daily lives.

Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids.

　To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50.

For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn’t matter what the differences in health or living conditions were between the two communities or from family to family.

Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died.

The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone’s lifespan.

So, don’t take your grandma for granted!

試題分析：本文通過社會調查，例舉了一些數字說明了在撫養孩子這方面，祖母所做的貢獻。

1.這是數字計算題。根據In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50.被調查的兩個地區中，芬蘭有537位女性，加拿大有3290位女性，是50歲以上的祖母或外婆，共計537 + 3290 = 3827（人）。故選C。

2.這是細節理解題。根據The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died.故選B。

3.這是細節理解題。根據最后一段“…grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone’s lifespan.”可知應選B。

4.這是細節理解題。根據Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born.可知D是不成立的。故選D。

考點：這是一篇社會調查。

點評：高考閱讀和聽力部分很可能出現數字計算題，需要考生認真仔細分析上下文，確定題干與文中提到的哪些數字有關。
