Question

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.

1.What’s the best title for this passage?

B. Tianhe-1A is developed by CAS and DIIC.

C. Tianhe-1A will use fewer than 10,000 Loongson microchips.

D. NUDT has produced a most powerful supercomputer in China.
4.The underlined word “affiliated” can be replaced by_______.

A. cheap B. suitable C. expensive D. modern

 

Answer 1

1.D

2.B

3.A

4.B

【解析】

试题分析：国产超级计算机将对外国芯片说再见而采取国产芯片同时还介绍了国产芯片研发和超级计算机的一些相关信息。

1.1】D 主旨大意题。由文章第一段可知。本文讲述的是国产的超级计算机将采用国产的芯片以及国产芯片研发和超级计算机的一些相关信息，选项B未能提及关键词supercomputers。故D正确。

2.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.可知提高运算速度的是Loongson microchips。

3.Nvidia, two US chip-makers.”可知。选项C主语应该是the new supercomputer而不是Tianhe-1A。

4.developed for these supercomputers”可知该词表示的是B项含义。
