    The money he has contributed in the past years to ______ the disabled is now considered to be of great value.

    A. help B. helping, C. having helped D. being helped

     

    B

    【解析】

    试题分析：本题中含有一个定语从句he has contributed in the past years to ______ the disabled，修饰先行词the money，在定语从句中省略了that/which指代先行词作为动词contribute的宾语，句中的to是一个介词，后面的helping作为介词to的宾语。句义：在过去的几年里他花在帮助残疾人身上的钱现在被认为是很有价值的。故B正确。

    考点：考察动名词用法和句子结构

    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.

    A. The Arrival of Chinese Supercomputers

    2.What will raise the speed to more than 1,000 trillion operations a second.?

    C. DIICD. Tianhe-1A

    3.What do we know about Tianhe-1A?

    A. Not all the parts of Tianhe-1A are made by China.

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

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