Researchers found that women who had given birth might have a reduced risk of death from several common conditions than those who had not，according to a study released Friday by the Imperial College London (ICL)．

The study，led by ICL researchers，was published in the journal BMC Medicine.It investigates the association between the so­called reproductive factors—such as having children and breastfeeding—and a woman's risk of death.

Researchers analyzed data from 322,972 women across 10 countries，including the UK，France，Germany and  Sweden，with an average age of 50.

Each woman was followed for an average of 12.9 years.During this period，there were 14,383 deaths overall，which included 5,938 deaths from cancer and 2,404 deaths from circulatory system diseases，according to the study.

The team compared reproductive factors with the risk of death from several common conditions，such as breast cancer，strokes and heart diseases.

The researchers found that women who had given birth had a 20 percent reduced risk of death than those who had not.It was also found that there was a reduced risk of death (8 percent) in women who had breastfed compared to those who had not.

The risk of death from cancer was lower in those who had given birth compared to those who had not.Within this  group，the risk was reduced even further in women that gave birth to two or three children in comparison to those who had only one child.

“Hormonal mechanisms may explain the lower risk of death that we observed with breastfeeding，and having given birth，as these factors are associated with changes in hormone levels，” said Dr Melissa Merritt from ICL，who led the study.

1．According to the passage，the risk of death from cancer is lower in women who________.

A．have given birth to no child

B．have given birth to one child

C．have given birth to more than one child

D．have breastfed

2．According to the research，if a woman has given birth and breastfed，her risk of death will decrease by________.

A．20%  B．28% 

C．12%  D．16%

3．Which of the following might be one of the findings of the research?

A．Several common conditions lead to women's death.

B．Reproductive factors are associated with changes in hormone levels.

C．Women who have given birth live longer than those who have not.

D．Having children might reduce women's risk of death from some diseases.

答案：[解题导语]研究表明，和没生育过孩子的妇女相比，生育过孩子的妇女患病死亡的概率会大大降低。

1．C　解析：细节理解题。根据倒数第二段中的“the risk was reduced even further in women that gave birth to two or three children in comparison to those who had only one child”可知，生育两个或三个孩子的妇女比只生育过一个孩子的妇女患癌症死亡的概率低。故选C项。

2．B　解析：细节理解题。根据第六段“The researchers found that women who had given birth had a 20 percent reduced risk of death than those who had not. It was also found that there was a reduced risk of death (8 percent) in women who had breastfed compared to those who had not.”可知，生育并且哺乳过的妇女死亡的概率会下降28%(20%＋8%)。故选B项。

3．D　解析：推理判断题。根据第一段中的“Researchers found that women who had given birth might have a reduced risk of death from several common conditions than those who had not”和第五段中的“such as breast cancer，strokes and heart diseases”可推断出，生育孩子会降低女性患病死亡的概率。故选D项。
