8、g 考查非谓语动词。thus 指代这是中国科学家第一次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 the first pulsar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 allow sb to do sth。 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 the next 10 to 20 years 可知,句子用一般将来时,所以填 will remain。
