Do you still get free plastic(塑料) bags from the supermarkets?  

Free plastic bags are not allowed at shops and supermarkets in China, and people have to pay for them. The rule started on June 1, 2009. It came because our country tried to make litter less. Making super-thin (超薄) plastic bags has not allowed.

The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

What kind of shopping bag is the best to bring? Some students in Chongqing city have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.

许多学者都谈到“勤”和“恒”这两者的重要性，我深有同感。假如有人问：治学有没有诀窍那么我想，勤和恒就是最基本的诀窍。勤能补拙，业精于勤，这是中国的古话。无数事实证明，任何一个人的任何一点成绩，都是从勤学、勤思、勤问中得来的。当然，勤和恒是不可分的。事实上，勤字中间就包含了恒的意思，譬如我们劝人多读书，决不是希望他读一本书，读一天书，而是希望他天天读，持之以恒，把每天读书养成习惯。
这段文字主要谈论的是( )。

A．“勤”和“恒”的重要性

B．治学的诀窍

C．“勤”和“恒”不能分开

D．勤能补拙，业精于勤

某时装公司拟投资4000万元开发一个时装设计生产项目，项目的成败取决于时装的设计是否符合流行趋势，且营销是否成功。通过采用专家调查法进行分析，认为可能出现四种状态：状态Ⅰ，设计符合流行趋势，产品营销获得成功，实现预定的营业收入；状态Ⅱ，设计符合流行趋势，但产品营销不成功，只能实现预定营业收入的80%；状态Ⅲ，设计不符合流行趋势，但成功的营销有效改善了销售效果，可以实现预定营业收入的50%；状态Ⅵ，设计不符合流行趋势，且产品营销失败，只能实现预定营业收入的30%。时装设计符合流行趋势及产品营销成功的概率预测见下表。

项目投资发生在第1年年初，当年投产运营。项目的寿命期3年，预定营业收入和经营成本数据见下表。在不同状态下经营成本保持不变。财务基准收益率为10%。

分析确定项目的风险变量，简述采用德尔菲法确定风险变量概率的步骤。
