下列关于中国四大名著之一的《西游记》的说法不正确的是（2分）（   ）

A．孙悟空是《西游记》的第一号人物，他乐观、聪明、勇敢、顽皮、灵活，热爱自由，除恶务尽，充满了斗争精神。其中大闹天宫、三打白骨精、三调芭蕉扇等情节都与他有关。

B．第十三回到第一百回是故事的主体，写孙悟空皈依佛门，与猪八戒、沙和尚一起保护唐僧去西天取经，一路经历九九八十一难，战胜了各路妖魔鬼怪，终于取到了真经，他们自己也修成了“正果”。

D．鲁迅先生分析《西游记》说，书中“神魔皆有人情，精魅亦通世故，而玩世不恭之意寓焉”。这是一个很深刻的观察。

     Five years ago, David Smith wore an expensive suit to work every day. "I was a clothes addict," he

jokes. "I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled." Today

David wears casual clothes-khaki pants and sports shirt-to the office. He hardly ever wears a necktie.

"I'm working harder than ever," David says, "and I need to feel comfortable."

      More and more companies are allowing their office workers to wear casual clothes to work. In the

United States, the change from formal to casual office wear has been gradual. In the early 1990s, many

companies allowed their employees to wear casual clothes on Friday, but only on Friday. This became

known as "dress-down Friday" or "casual Friday". "What started out as an extra one-day-a-week benefit

for employees has really become an everyday thing." said business consultant Maisly Jones.

     Why have so many companies started allowing their employees to wear casual clothes? One reason is

that it's easier for a company to attract new employees if it has a casual dress code. "A lot of young people don't want to dress up for work," says the owner of a software company, "so it's hard to hire people if you have a conservative dress code." Another reason is that people seem happier and more productive when

they are wearing comfortable clothes. In a study conducted by Levi Strauss Company, 85 percent of

employers said that they believe that casual dress improves employee morale(士气). Only 4 percent of

employers said that casual dress has a negative effect on productivity. Supporters of casual office wear

also argue that a casual dress code helps them save money. "Suits are expensive, if you have to wear one

every day," one person said. "For the same amount of money, you can buy a lot more casual clothes."

11月27日至28日，全国稳定发展粮食生产座谈会在安徽省合肥市召开，会议预测今年我国粮食总产可望超过1万亿斤，将实现连续第四年增产，同时也指出在新的粮食生产形势下，保障国家粮食安全的任务也越来越艰巨。农业部副部长危朝安指出，在去年基数较高、气象和生物灾害偏重、政策效应递减的情况下，今年粮食仍然获得大丰收，而且破解了过去长期困扰我们的一些矛盾和问题。连续四年增产，扭转了过去很长一段时间“两增一减”或“两增一平”的局面；解决了增粮不增收的难题，在惠农政策强有力的推动下，加上结构优化和产业化发展，粮食生产实现了产量和效益同步提升，种粮农民收入连续保持较高速度增长。今年安徽粮食带动全省农民人均增收62元；产量和质量同步提高，化解了高产与优质的矛盾。预计2007年水稻、小麦、玉米、大豆优质率将分别提高17.7个、24个、18.8个和22.3个百分点；粮食作物和经济作物协调发展，走出了“粮上经下”或“经上粮下”的怪圈，在粮食连年增产的形势下，棉花、糖料总产均创历史新高，蔬菜、水果等产品数量充足，花色品种丰富，基本实现均衡供应。危朝安说，总结今年粮食增产的经验，可以看到今年中央和各地领导高度重视，惠农政策和财政支持力度也是前所未有的，今年种粮农民直接受惠的财政支农投入将超过700亿元，比上年增长30%以上；科技创新和技术推广为粮食丰收做出了巨大贡献，安徽的“小麦高产攻关活动和水稻产业提升行动”、陕西的“小麦标准化示范工程”、江苏的“水稻精确定量栽培技术示范方”、山东的“玉米千斤省行动”等，把专家产量变成了农民产量，把试验产量变成了推广产量；优质粮食产业工程、种子工程、植保工程、沃土工程等一批重大工程项目，也有力地促进了粮食综合生产能力的提升；针对今年偏重发生自然灾害和生物灾害，各地沉着应对，最大限度地减少粮食生产损失，通过防控病虫害，河南挽回小麦产量损失60亿斤以上，湖北预计挽回粮食损失100亿斤。1万亿斤的跨越标志着我国粮食生产从恢复发展跨入稳定发展的新阶段，但是综合国际粮食市场变化、气候条件、农业劳动力结构、资源约束性等因素来看，保障国家粮食安全的压力将越来越大，仍然是我国经济社会发展中最突出的矛盾和最艰巨的任务，也是我们必须着力解决的长期性、战略性问题。
