能源、环境与人类生活和社会发展密切相关,研究它们的综合利用有重要意义。 (1)氧化—还原法消除氮氧化物的转化如下: ①反应Ⅰ为:NO+O3=NO2+O2,生成11.2 L O2(标准状况)时,转移电子的物质的量是     mol。 ②反应Ⅱ中,当n(NO2)∶n[CO(NH2)2]=3∶2时,反应的化学方程式是              。 (2)硝化法是一种古老的生产硫酸的方法,同时实现了氮氧化物的循环转化,主要反应为:NO2(g)+SO2(g)SO3(g)+NO(g)  △H=-41.8 kJ·mol-1已知:2SO2(g)+O2Girls should take part in competitive sport to build confidence, the leader of a group of girls’schools will argue this week. Helen Fraser, director of the Girls Day School Trust (GDST), will tell the group that sport can help girls cope with failure.“All girls and not just the sporty ones should take physical exercise”, Ms Fraser will say. Research that girls are far less active than boys is worrying, she argues. Ms Fraser will tell the group that she backs “sport for all”. “That’s why I love it when our schools have A, B, C and D teams and beyond”, she will say.The GDST draws on research from the Women’s Sport and Fitness Foundation which suggests only a quarter of girls in England meet basic levels(水平)of activity each week. One in five girls do no activity at all, twice the proportion (比例)of boys, the research suggests.Ms Fraser says other research suggests that more than 80% of women business leaders played sports while growing up. She uses the examples of US Secretary of State Condoleezza Rice, once a skater and tennis player, while the head of the International Monetary Fund, Christine Lagarde, was in the French national swimming team. Ms Fraser says Olympic medallists like Jessica Ennis, Katherine Grainger and Nicola Adams are excellent role models for young women but says women’s sport needs more money and more news reports.Valerie Dunsford, head of Sheffield High School, part of GDST, said it was important to offer a large number of sports to attract different types of girls. “Not everyone wants to be out playing the hockey (曲棍球)”, said Ms Dunsford.【1】Which of the following ideas would Ms Fraser agree with?A. Those taking part in the sport are always failures.B. More should be done to make girls do sports.C. Girls are less confident than boys.D. Boys are born to be sport lovers.【2】What’s the proportion of boys who never take exercise?A. 1/10. B. 1/4.C. 1/5. D. 2/5.【3】Ms Fraser mentions those famous women to show ________A. hard work will pay off.B. it’s not easy to be great.C. sport can help girls to succeed.D. it’s necessary to balance work and sport.【4】What’s the purpose of the text?A. To explain the key to success.B. To show the importance of sport.C. To introduce more games to girls.D. To encourage more girls to do sports.
