Question

Professor Smith, along with his assistants, _____on the Project day and night to meet the deadline. A．work B．working C．is working D．are working

Answer 1

C

试题分析：参考主谓一致。本句的主语是Professor Smith, along with his assistants，谓语动词要和前面的名词Professor Smith保持一致，故使用单数形式，排除AD项。B项不能单独做谓语。句意：史密斯教授和他的助手在夜以继日地做这项工作，以赶上最后期限。故C正确。 点评：主谓一致主要指“人称”和“数”方面的一致关系。对大多数人来说，往往会在掌握主语和随后的谓语动词之间的一致问题上遇到困难。一般情况下，主谓之间的一致关系由以下三个原则的支配：语法一致原则 (grammatical concord) 意义一致原则 (notional concord) 就近原则 (principle of proximity)。“主谓一致”考查内容涉及名词单数或复数作主语、不可数名词作主语、不定代词作主语、并列结构作主语、特殊名词作主语时与谓语动词数的一致等。
