A. 请将四封信与问题进行配对，并把序号A、B、C、D填入1-4 题题后相应的横线上。

Dear Editor ,
I am a student from a junior middle school. I am good at all subjects except English. I can’t remember words well. I am especially weak in speaking and listening. What shall I do?
John

Dear Editor ,
I have a problem! I really don’t know what to say when I meet strangers . I find it hard to
talk with others because I’m afraid they might laugh at me. I am not as clever or funny as my
friends. If people start talking to me, they will realize that I am just boring. Please help me.
Lily

Dear Editor,
I was getting on well with my best friends. But a few days ago, another friend of mine told me that she often said bad words about me. When I heard this, I was very angry. What should I do? Should I stop being her friend or stay with her as usual?
Betty

Dear Editor,
Recently I have much difficulty in falling asleep. When I go to bed, I feel very sleepy, but I
always think a lot and can’t fall asleep. So I always feel very tired in class and sometimes my
head hurts badly. Could you give me some advice?

问答题

某项目有三个主要风险变量：固定资产投资、年销售收入和年经营成本，数据及其概率分布见表1-1。

表1-1 主要风险变量数据及其概率分布表

固定资产投资/万元		年经营成本/万元		年销售收入/万元		寿命/年
数值	概率	数值	概率	数值	概率	数值	概率
80000	1.00	12000	1.00	20000	0.30	18	0.20
				25000	0.40	20	0.40
				30000	0.30	22	0.40
合计					1		1

其中贴现率为10%，计算该项目经济效益期望值。

列出各参数不同取值的组合，并计算每种组合下方案的净现值及其相应的组合概率。
