题目

关于化学反应，下列说法不正确的是( )A.该反应条件是点燃B.该反应为化合反应C.该反应为吸热反应D.参加反应的碳和氧气的质量比为3:8 答案：【答案】C【解析】A、由化学方程式可知，该反应条件是点燃，故正确；B、此反应是两种物质化合生成一种物质，属于化合反应，故正确；C、碳在氧气中充分燃烧，放出大量的热，故错误；D、每12份质量的碳和32份质量的氧气完全反应生成44份质量的二氧化碳，所以参加反应的碳和氧气的质量比为12:32=3:Edith Cavell was born in a little English village. She was a clever, hard-working girl and did well at school,especially in music and French. After she left school, her first job was to take care of the children of a rich family in Belgium（比利时）. The language they spoke was French, so she found that her school studies were useful. She could understand them easily, at the same time she taught the children to speak English and play the piano.After hearing that her father was seriously ill, Edith returned home to look after him. She then decided to become a nurse. Afterwards for five years she worked in an English hospital where she proved to be highly professional（专业的）at her job. A Belgian doctor was so impressed（印象深的）that he invited her to his country to organize a training school for nurses. The First World War (第一次世界大战) broke out in 1914 and Edith Cavell’s school of nursing became a hospital. She stayed there to look after the sick and wounded soldiers (伤员). Edith treated them with kindness. Between November 1914 and August 1915 she secretly helped about 200 wounded soldiers and prisoners (囚犯) escape from the Germans. Later the German army found out what Edith had done and they arrested her. Finally, the Germans killed her, but they could not kill her memory. A tall statue（雕塑）has been built in Trafalgar Square, London, in honor（纪念）of the brave English nurse.根据材料内容选择最佳答案, 并将其标号填入题前括号内。1.Edith Cavell was from __________.A. France B. EnglandC. Belgium D.
