Analyze sme imprtant sentences(1) We see a wman swimming at night in a dark sea. 我们看见一个女人晚上在深色的海里游泳。分析:see a wman swimming ( see +宾语+ding做宾补:“看见某人正在做事”) ding做宾补,表示与宾语之间是主动关系,且表示正在进行。【知识链接】see sb. d (与sb.是主动关系,动作完成) see sb./ sth. dne (表示与宾语是被动关系)【实战演练】a. I saw him ging ut when I came in. b. I saw him g ut. c. I saw the by beaten by his father just nw.
(2)She surfaces, cries in fear, and then disappears frever. (这个句子是3个并列谓语,正式的语法结构,d, d, and d。原文不太正式)她浮出水面,恐惧地叫喊,之后永远地消失了。【知识链接】容易与分词做状语混淆--看清结构与意义。 a.
