试题解析

肾盂

肾盂是由肾大盏合并成的漏斗状扁囊。位于肾窦内,出肾门后移行于输尿管。成人肾盂的容积约3~10毫升(平均7.5毫升)。尿道逆行感染易引起该部炎症、储脓乃至肾盂肾炎;肾结石多于该处集聚。其表面投影位于第12肋与骶棘肌(竖脊肌)外缘形成的夹角处,患者可于该部产生触压痛或叩击痛。

肾盏

在肾窦内有7~8个呈漏斗状的组织,称之为肾小盏,肾小盏包绕肾乳头。2~3个肾小盏合成一个肾大盏。2~3个肾大盏汇合成一个前后扁平的、漏斗状的肾盂。

Passage 1  The human race is using up the Earth's resources faster than ever before, according to a new report by the United Nations Population Fund. “Environmental devastation is not simply a waste of 1, it is a threat to the complex structures that 2human development,” says the report.  3 attention must be paid to find a(n)  4 between human and environmental needs, it says.  The report, State of the World Population 2001, says that water supplies and agricultural lands are coming  5 such increasing pressure that, if left  6 , our planet will not be able to support us in future years. Over the past 70 years, the world’s population has tripled to 6.1 billion people,  7 water-use increasing six-fold, says the report. Already 508 million people live in 31 countries that lack water. And the problem is likely to  8 as the global population is  9 to rise to eight billion by 2025.  By 2050, predicts the report, 4.2 billion people will be living in countries that cannot meet people's daily  10 needs. Unclean water and poor sanitation already kills over 12 million people every year. Food production is also  11 by environmental problems, says the report. “To  12 the future population and improve their diets, the world will have to double food production,” it says. “But since available cropland is  13 , most production will have to come from higher  14 rather than new  15 .”  According to the report, global poverty cannot be  16 without  17 the environmental damage caused by these increases in consumption and population  18 . To reduce the burden on the planet, the report suggests, all efforts should be  19 to improve education and healthcare, as this would  20 reduce population growth.1.

某16位计算机中,带符号整数用补码表示,数据Cache和指令Cache分离。下表给出了指令系统中部分指令格式,其中Rs和Rd表示寄存器,mem表示存储单元地址,(X)表示寄存器X或存储单元X的内容。  该计算机采用5段流水方式执行指令,各流水段分别是取指(IF)、译码/读寄存器(ID)、执行/计算有效地址(EX)、访问存储器(M)和结果写回寄存器(WB),流水线采用“按序发射,按序完成”方式,没有采用转发技术处理数据相关,并且同一个寄存器的读和写操作不能在同一个时钟周期内进行。请回答下列问题。  (1)若int型变量x的值为-513,存放在寄存器R1中,则执行指令“SHR R1”后,R1的内容是多少?(用十六进制表示)  (2)若某个时间段中,有连续的4条指令进入流水线,在其执行过程中没有发生任何阻塞,则执行这4条指令所需的时钟周期数为多少?  (3)若高级语言程序中某赋值语句为x=a+b,x、a和b均为int型变量,它们的存储单元地址分别表示为[x]、[a]和[b]。该语句对应的指令序列及其在指令流水线中的执行过程如下图所示。则这4条指令执行过程中,I3的ID段和I4的IF段被阻塞的原因各是什么?  (4)若高级语言程序中某赋值语句为x=2×x+a,x和a均为unsigned int类型变量,它们的存储单元地址分别表示为[x]、[a],则执行这条语句至少需要多少个时钟周期?要求模仿上图画出这条语句对应的指令序列及其在流水线中的执行过程示意图。
