sb.，“我们”用宾格“us”，主语从句中缺少主语，指事情，所以此处由“what”引导，位于句首，首字母需大写，句子描述客观情况用一般现在时，“what”视为单数，谓语动词“worry”用第三人称单数“worries”，所以第一空为What worries us。第二空需补充“谁泄漏了秘密”，在句中作表语，需用表语从句，“泄漏秘密”用固定短语“let out the secret”，“泄漏秘密”是已发生的动作，用一般过去时“let out”，从句中缺少主语，且指人，使用连接代词who引导表语从句，所以第二空填who let out the secret。故填①What worries us②who let out the secret。 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 The Jade Burial Suit (金缕玉衣),

Using archaeobotanical analysis 54 radiocarbon dating, researchers identified 45 carbonized adzuki beans 55 more than 32,000 plant remains collected from the site. “This finding predates previously known adzuki beans in China by some 4,000 years,” said Chen, the paper’s first author. The beans, 56 date back to roughly 9,000 years ago, provide direct evidence that an early mixed cropping system of “grains and legumes (豆科作物)” 57 (form) in the Yellow River basin by that time. The study, 58 (joint) conducted by scholars from different 59 (university) and institutes, challenges the long-held belief that adzuki beans originated solely in Japan. “The discovery provides solid archaeological evidence that adzuki beans 60 (consume) and possibly cultivated in China as early as 9,000 years ago, demonstrating that China was also one of the centers of origin of this important legume,” said Zhao, a professor at Shandong University. 【答案】 51．published 52．international 53．dating 54．and 55．among 56．which 57．had formed 58．jointly 59．universities 60．were consumed 【导语】这是一篇说明文。主要说明了研究证实中国是小豆起源地之一，山东出土约九千年前碳化小豆，将已知历史提前四千年，为黄河流域旱作农业提供考古证据。 51．考查非谓语动词。句意：据由中国学者领导的一个国际研究团队近期在《美国科学院院报》上发表的一项研究显示，中国已被确认为小豆（学名：Vigna angularis）的起源中心之一。此处publish与study构成被动关系，故用过去分词作定语。故填published。 52．考查形容词。句意：据由中国学者领导的一个国际研究团队近期在《美国科学院院报》上发表的一项研究显示，中国已被确认为小豆（学名：Vigna angularis）的起源中心之一。修饰名词team用形容词international，作定语。故填international。 53．考查非谓语动词。句意：该团队在山东省淄博市后李文化遗址的小高遗址发现了约9000年前的碳化小豆遗存。此处date与remains构成主动关系，故用现在分词作定语。故填dating。 54．考查连词。句意：通过考古植物学分析和放射性碳年代测定技术，研究人员在从该遗址采集的超过32000件植物遗存中，鉴定出了45颗碳化的小豆。连接两个并列的名词短语 archaeobotanical analysis 和radiocarbon dating用连词and。故填and。 55．考查介词。句意：通过考古植物学分析和放射性碳年代测定技术，研究人员在从该遗址采集的超过32000件植物遗存中，鉴定出了45颗碳化的小豆。表示“在三者或三者以上中”用介词among。故填among。 56．考查定语从句。句意：这些豆类可追溯到约9000年前，它们为当时黄河流域已形成“谷物与豆类”混合种植体系提供了直接证据。非限制性定语从句修饰先行词beans，在从句作主语，指物，故填which。 57．考查时态。句意：这些豆类可追溯到约9000年前，它们为当时黄河流域已形成“谷物与豆类”混合种植体系提供了直接证据。根据后文by that time可知表示在过去某个时间以前已经完成的动作，用过去完成时。故填had formed。 58．考查副词。句意：这项研究是由来自不同大学和研究机构的学者共同开展的，它挑战了长期以来人们所秉持的“红豆仅起源于日本”的观点。修饰动词conduct用副词jointly，故填jointly。 59．考查名词的数。句意：这项研究是由来自不同大学和研究机构的学者共同开展的，它挑战了长期以来人们所秉持的“红豆仅起源于日本”的观点。根据上文different可知为复数。故填universities。 60．考查时态语态。句意：山东大学的赵教授表示：“这一发现为考古学提供了确凿的证据，表明早在9000年前，中国就已经食用并可能种植红豆了，这表明中国也是这种重要豆类的起源中心之一。”主语adzuki beans与谓语构成被动关系，根据后文as early as 9,000 years ago可知为一般过去时的被动语态，谓语用复数。故填were consumed。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $
