下列关于略读部分四首诗内容和艺术手法的理解有误的一项是[ ]

A．《也许——葬歌》淋漓尽致地表达了生者告别死者的哀伤，哀婉而不悲惨，真挚而不夸饰。诗人没有刻意渲染，而是平静地娓娓道来，看似无章，实则有法，像是轻描淡写，实则激情内蕴，读来令人黯然销魂。

B．《一个小农家的暮》语言质朴无华而富有变化。在写女主人公时运用色彩的变化来映衬她的勤劳、娴淑和美丽。“灶门里嫣红的火光，／闪着她嫣红的脸，／闪红了她青布的衣裳。” “嫣红”和“青布”是颜色的鲜明对比，动词“闪”逼真地写出了火光闪动的画面，生动地描写了农家生活中最细腻的厨房场景。

C．诗是最精练的语言艺术，最忌讳词语重复，《秋歌— 给暖暖》却出现了五个“暖暖”（题目中一个，诗中四个），十个“暖”，可称白璧微瑕。

D．江非的《妈妈》选取的意象是现代化文明的产物，而不是妈妈身边的事物，这些在都市里司空见惯的事物对一个偏远农村的妇女来说是那么遥远和陌生，暗示现代文明与乡村文明的距离。

We know a computer is a machine that processes data (stored in main memory) into information, under control of a stored program. We also know that, internally, a computer is a binary machine; thus the data and the program instruictions must be stored in binary form. Characters are represented in (71) . Numbers are stored as binary numbers, with each bit’s positional value significant. A computer’s main memory is divided into bytes, words or both (depending on the system), and each of these basic storage units is assigned an (72) . Using this address, the processor can read or write selected bytes or words.

The processor consists of a clock, an instruction control unit, an arithmetic and logic unit, and registers. Once a program is stored in main memory, the processor can begin to execute it. During (73) , the instruction control unit fetches an instruction from main memory; during (74) , the arithmetic and logic unit executes it. Precisely timed electronic pulses generated by the clock drive this basic (75)
