如图是电冰箱的简化电路图．图中M是电冰箱压缩机用的电动机，L是电冰箱内的照明灯．根据你平时对冰箱的观察，下列判断正确的是A.开关S1闭合，S2断开时，照明灯L与电动机

Saturday, October 7th, was a marathon of sad tasks for Anna Politkovskaya. Two weeks earlier, her father, a retired official in the department of foreign affairs, had died of a heart attack as he emerged from the Moscow Metro while on his way to visit Politkovskaya’s mother, Raisa Mazepa, in the hospital. She had just been diagnosed(诊断) with cancer and was too weak even to attend her husband’s funeral. “Your father will forgive me, because he knows that I have always loved him,” she told Anna and her sister, Elena Kudimova, the day he was buried. A week later, she had an operation and since then Anna and Elena had been taking turns helping her deal with her grief.
Politkovskaya was supposed to spend the day at the hospital, but her twenty-six-year-old daughter, who was pregnant, had just moved into Politkovskaya’s apartment, on Lesnaya Street, while her own place was being prepared for the baby. “Anna had so much on her mind,” Elena Kudimova told me when we met in London, before Christmas. “And she was trying to finish her article.” Politkovskaya was a special reporter for the small newspaper Novaya Gazeta, and, like most of her work, the piece focused on the terror that can be seen all over the southern republic of Chechnya. This time, she had been trying to report repeated cruel acts done by people faithful to the Prime Minister, Ramzan Kadyrov, who are in favour of Russia. In the past seven years, Politkovskaya had written dozens of accounts of life during wartime; many had been collected in her book “A Small Corner of Hell: reports from Chechnya.” Politkovskaya was far more likely to spend time in a hospital than on a battlefield, and her writing bore frequent witness to robbery, and the uncontrolled cruelty of life in a place that few other Russians—and almost no other reporters—cared to think about.
【小题1】 Politkovskaya’s father died of .A．tirednessB．a diseaseC．an attackD．an accident【小题2】From the text we know that Raisa Mazepa .A．didn’t love her husbandB．didn’t attend her husband’s funeralC．was having an operation the day her husband was buriedD．was too sad to attend her husband’s funeral【小题3】The underlined word “emerged” most likely means .A．came outB．went intoC．looked intoD．left for【小题4】How many family members of Anna are mentioned in the passage?A．Three.B．FourC．FiveD．Six【小题5】Which of the following words can best describe Politkovskaya’s character?A．curiousB．easy-goingC．carelessD．responsibleB

(答案→)B 解析：【小题1】答案B。从第2句中的“…had died of a heart attack…”可知B选项是正确答案。C选项attack是“攻击”的意思，而文中出现的是heart attack，“心脏病”，因此C选项偷换了概念；其他选项与文中相关的表述不相干。【小题2】答案B。从3、4、5三句可知B选项是正确选项，其他三个选项与文中的表述不一致。【小题3】答案A。介词“from”表示动作的出处、来源，而后面的介词宾语是“the Moscow Metro”，可知“Moscow Metro”是“emerged”这一动作的起源地，因此，A选项符合原文的意思。【小题4】答案C。文中提到Politkovskaya姐妹俩，以及她的父母、女儿。【小题5】答案D。从“Politkovskaya was a special reporter for the small newspaper Novaya Gazeta,…”一直到文章的结尾，作者简述了Politkovskaya敢于直面社会的不良现象的正值性格，而这是其他记者所不屑的，因此D选项是正确答案。

D解析分析：根据生活经验，明确电冰箱工作时的特点，认真分析电路图，结合串并联电路的特点判断电路中电动机与电灯的连接．解答：A、开关S2断开、S1闭合时，照明灯不工作，只有电动机工作，故A错误；
B、打开冰箱门时，S2自动闭合，照明灯工作，故B错误；
C、冰箱内温度降低到设定温度时，S1自动断开，电动机停止工作，这是压缩机工作的一般原理；故C错误；
D、开关S1、S2都闭合时，照明灯L与电动机M并联，故D正确．
故选D．点评：本题考查了电冰箱的工作电路．电冰箱中电灯与压缩机是并联关系，能够独立工作，互不影响；知道温控开关与压缩机用的电动机串联才能控制压缩机工作情况．
