下列词语中没有错别字的一项是(   )

A.现在是把我们的国家从种族不平等的流沙中拯救出来,置于兄弟情谊的磬石上的时候。

B.突然他又带着加倍的失望在锁琏里挣扎,把他身子底下的木板都震动了,用嘶哑又愤怒的声音吼叫。

C.女工们先是在相貌凶恶的女军官的威逼下剪去头发,接着在鞭子的驱赶下提心掉胆地相拥着挤进挂满水龙头的大棚屋。

D.难道我们就这样仰面高卧,紧抱着那虚无缥缈的和平幻觉不放,直到敌人把我们束缚起来的时候,才获得有效的防御手段吗?

答案

D

题目分析:此题命题形式较为新颖,将字形与具体语境有机地融合在了一起。A“磬”应为“磐”,为形近字误用;B“琏”应为“链”,因是用铁制成,因此形旁为金字边;C“掉胆”应为“吊胆”,是悬挂的意思,因此字形为吊。平时复习要把字形与字义有机地结合在一起,要在理解的基础上识记字形。

BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips(微芯片) and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.

Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.

Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.

According to their schedules, all three institutions will need to meet the target of using domestically(国内的) developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.

Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.

Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.

Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.
