 课时作业(九) Ⅰ.阅读理解[2017·湖北八校联考]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 childB．have given birth to one childC．have given birth to more than one childD．have breastfed2．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。Ⅱ.阅读填空[2017·黑龙江牡丹江一中期末]As a health editor，I spend the majority of my day applying my mind to contents related to health.We're lucky to talk to experts on a daily

appreciate life...可知，本段主要讲要花点时间感恩生活。故选A项。5．D　解析：本段主题是找到一项你真正喜欢的运动。设空前说我喜欢像排球一样的运动，那么，对于你来说，也应该有自己喜欢的运动。故选D项。Ⅲ.语法填空[2017·云南昆明七校调研]During a recent Senior Three English lesson，the teacher

sb.意为“与某人分享某物”，为固定搭配，故用介词with。3．truly　解析：考查副词。修饰动词应用副词，故用副词truly修饰动词enjoyed。注意true变副词时去掉字母e加ly。4．a　解析：考查冠词。discussion在此处表示具体概念，且第一次在语境中出现，故用不定冠词a修饰。5．creative　解析：考查形容词。how修饰形容词或副词。由下文的be可知，此处应用形容词作表语，故用creative。6．what　解析：考查名词性从句。空处引导主语从句，在从句中作主语，表示物的概念，what符合语境。7．suggestions　解析：考查名词。her是形容词性物主代词，修饰名词，故用名词形式。此外，suggestion是可数名词，由Many of可知，应用复数形式。8．ourselves　解析：考查代词。由句子主语we可知，此处应用反身代词，表示放松自我。9．writing　解析：考查非谓语动词。write和从句的谓语works之间没有连词，故用非谓语动词。其与主语he构成逻辑上的主谓关系，故用现在分词作伴随状语。10．to finish　解析：考查非谓语动词：have time to do sth.意为“有时间做某事”，为固定搭配，不定式作宾语补足语。Ⅳ.短文改错[2017·浙江余姚中学暑期质检]I have a classmate named Angel，who is a lovely and bright girl.She is popular from all the classmates.One day，news came as Angel had got blood
