23、evolutionize other 9.(area) of the natural sciences.It 10.(remain) the global leader for the next 10 to 20 years.答案与解析【语篇解读】本文是一篇说明文。文章报道了中国科学家第一次使用自主研发的射电望远镜发现并确定了六颗脉冲星。1.known考查非谓语动词。主语Five-hundred-meterApertureSphericalRadioTelescope和动词know是逻辑上的动宾关系,所以用动词-ed形式作定语。2.opening考查非谓语动词。thus指代这是中国科学家第一次
24、使用由中国科学家自主研发的射电望远镜发现脉冲星。这一发现和动词open是主动关系,所以用动词-ing形式作结果状语。3.was discovered考查语态。主语thefirstpulsar和动词discover是被动关系,动作发生在过去,所以用一般过去时的被动语态。4.in/within考查介词。此处指几乎所有的脉冲星都在银河系的范围内,表示“在内”用in/within。5.to find考查非谓语动词。表示“允许某人做某事”用allowsbtodosth。6.scientific考查形容词。此处修饰名词data,所以用形容词形式,故填scientific。7.which考查定语从句。此处是非限制性定语从句,用关系代词which引导,指代前面整个句子。8.a考查冠词。句中road是单数可数名词,此处指其创新的工程理念和设计铺设了一条新路,表示数量一,故填a。9.areas考查名词。句中area是可数名词,由other修饰用复数形式,指其他领域,故填areas。10.will remain考查时态。根据时间状语thenext10to20years可知,句子用一般将来时,所以填willremain。
