C．echo UserHome directory:$LOGNAME echo Current shell's PID：$@

D．echo UserHome directory:$HOME echo Current shell's PlD:$$


正确答案：D
解析：Unix系统有很多种产品，每种产品的命令略有不同，但基本一致。Shell环境定义了Unix与用户进行交互的方式。环境特性由包含名称和值的环境变量定义。以下是一些常见的缺省设置的环境变量。(1)HOME定义用户的主目录；CD命令的缺省目录。(2)LOGNAME包含用户名。(3)MAIL确定系统查找邮件的位置。(4)PATH设置系统用于查找并执行命令的目录。(5)SHELL决定运行的shell。(6)TERM指定准备输出的终端类型。(7)TZ提供当前时区及其与格林威治标准时间的差值。(8)EDITOR确定缺省的编辑器。(9)DISPLAY指定窗口显示主机。在Shell命令中，echo命令可以显示Shell变量的内容或值。在Shell中有一些特殊意义的变量，由Shell自己管理，这些特殊变量有：(1)$#内存位置参数的个数。(2)$$当前命令的进程标识符。(3)$1最后一个后台进程的标识符。(4)$*所有位置参数字符串。(5)$@与$*相似(但与$*的值略有区别)。

第8题：

3 The managers of Daylon plc are reviewing the company’s investment portfolio. About 15% of the portfolio is represented by a holding of 5,550,000 ordinary shares of Mondglobe plc. The managers are concerned about the effect on portfolio value if the price of Mondglobe’s shares should fall, and are considering selling the shares. Daylon’s investment bank has suggested that the risk of Mondglobe’s shares falling by more than 5% from their current value could be protected against by buying an over the counter option. The investment bank is prepared to sell an appropriate six month option to Daylon for ￡250,000.

Other information:

(i) The current market price of Mondglobe’s ordinary shares is 360 pence.

(ii) The annual volatility (variance) of Mondglobe’s shares for the last year was 169%.

(iii) The risk free rate is 4% per year.

(iv) No dividend is expected to be paid by Mondglobe during the next six months.

Required:

(a) Evaluate whether or not the price at which the investment bank is willing to sell the option is a fair price.(10 marks)


正确答案：

3 (a) The investment bank is offering to sell to Daylon plc an option to sell Mondglobe ordinary shares at a price no worse than 5% below the current market price of 360 pence. This is a put option on Mondglobe shares at a price of 342 pence. The Black-Scholes option pricing model may be used to estimate whether or not the option price is a fair price. The value of a put option may be found by first estimating the value of a call option and then using the put-call parity theorem.
Basic data:
Share price 360 pence
Exercise price 342 pence
Risk free rate 4% (0·04)
Volatility is measured by the standard deviation. The variance is 169% therefore the standard deviation, σ is 13% (0·13)
The relevant period is six months (0·5)

第10题：

资料：The soybean prices ended higher this Monday as traders expect supplies to remain tight.
The actively July contract for soybeans rose 20 cents to settle at $14.85 a bushel.
The U.S. government's weekly prediction for soybean exports was higher than traders expected, said Mike Zulo. President of a consulting company in Atchison, Kansas.
Supplies for beans have been extraordinarily tight as China's demand for soymeal continues to increase even as U.S. production stays relatively steady, he said. Soybean prices have risen about 15 percent this year.
“That U.S.D.A. number caused the trade to refocus on just how razor-thin supplies are heading in to next fall's harvest.” Zulo said.

Why did the prices of soybean rise according to the passage?

A.Because the general production of soybean stayed steady.
B.Because the supplies were expected to keep tight.
C.Because China’s demand for soybean increased.
D.Because the trade of soybean was quite active.
