2018 公共英语四级考试语法解析:复合句
复合句
复合句考查的主要内容是宾语从句、状语从句和定语从句。
①宾语从句
宾语从句的考查要点是:时态的呼应、人称的一致、词序等。
A.宾语从句的连接词:宾语从句本身是叙述句是,用that 引导。He said (that) he would leave on March 12 next weeek.宾语从句本身是特殊疑问句时,用疑问词引导。 Do you know where we can find our teacher?宾语从句本身是一般疑问句时,用if 或whether引导。I don't know if / whether he has done that.
B. 宾语从句与主句时态的呼应。主句谓语是现在时和将来时的时候,宾语从句的动词时态不受影响。如,It is said that the panda was sent to America last month.主句是过去时态,从句谓语要做适当调整:
a)由现在时调整为过去时。I didn't know you were also here.
b)由将来时调整为过去将来时He said that he would go to Beijing the next week.
c)过去时态多数不受影响,但"一般过去时"常调整为"过去完成时",尤其是从句中有before, since 一类的时间状语时,多调整为"过去完成时"如:She said she had worked at this school before her father came to this city.
②状语从句
状语从句有时间状语从句(常由when, while, before, after, until, as soon as等词引导)、地点状语从句(常有where 引导)、原因状语从句(常有because, since, as 引导,这三词所表达的语气由because到as逐渐减弱,由why提出的问题必须用because 来回答), 条件状语从句(常由if引导)、结果状语从句(常由such … that…, so…that…, so that等引导 )、让步状语从句(常由though, although引导)。
③定语从句
其考查内容主要是正确使用关系代词{who(指人)、that(指人或物)、which(指物)} , etc. 定语从句一般紧跟在修饰词的后面,如:She is the person who I want to see. 她就是我想见到的人。有时,为了使句子平衡,也可把定语从句与所修饰词分开。
