Direct Speech
Indirect Speech
Wrk in grups. Lk at the sentences in bth clumns and discuss the differences between each pair. Summarise the rules fr changing direct speech int indirect speech.
直接引语 & 间接引语
英语中常用两种方式引用别人说的话。一种是直接引述别人的原话，把它放在引号内，叫直接引语；另一种是用自己的话转述别人说的话，叫间接引语。She said, “I’m an English teacher.”她说：“我是一名英语老师。”（直接引语）→ She said that she was an English teacher. 她说她是一名英语老师。（间接引语）
如果把直接引语变为间接引语，从句中的人称、时态、指示代词、时间状语和地点状语等一般均要做相应的改变。其变动的一般规则如下：一、人称变化的三原则1. “第一人称随主”原则如果直接引语中的主语是第一人称或被第一人称修饰，在间接引语中，从句中的人称要按照主句中主语的人称而变化。Mary said, “I want t have a cmputer f my wn.”玛丽说：“我想有一台我自己的电脑。”（直接引语中为第一人称）→ Mary said that she wanted t have a cmputer f her wn.玛丽说，她想拥有一台她自己的电脑。（间接引语中随主语改为第三人称）
如果把直接引语变为间接引语，从句中的人称、时态、指示代词、时间状语和地点状语等一般均要做相应的改变。其变动的一般规则如下：一、人称变化的三原则2.“第二人称随宾”原则如果直接引语中的主语及宾语是第二人称或被第二人称修饰，在间接引语中，从句中的人称要跟引号外的主句的宾语一致。Her clleague said t her, “Wh did yu ask fr a leave?”她的同事问她：“你向谁请假了？”（直接引语中为第二人称）→ Her clleague asked her wh she had asked fr a leave.她的同事问她向谁请假了。（间接引语中随宾语改为第三人称）
如果把直接引语变为间接引语，从句中的人称、时态、指示代词、时间状语和地点状语等一般均要做相应的改变。其变动的一般规则如下：一、人称变化的三原则3.“第三人称不更新”原则直接引语变间接引语时，如果直接引语中的主语及宾语是第三人称或被第三人称修饰，在间接引语中，从句中的人称一般不需要变化。Mr Li said, “Jack is a gd wrker.”李先生说：“杰克是一位好工人。”（直接引语为第三人称）→ Mr Li said Jack was a gd wrker.李先生说杰克是一位好工人。（间接引语中人称不变）
二、时态的变化直接引语变间接引语时，如果主句为过去时态，则间接引语的时态相应向前（向过去）推一个时态。如下表所示：
二、时态的变化直接引语变间接引语时，如果主句为过去时态，则间接引语的时态相应向前（向过去）推一个时态。【注意】当直接引语是客观真理、谚语或格言的情况下，直接引语变间接引语时，时态无变化。My teacher said t us yesterday, “Early birds catch wrms.”昨天老师对我们说：“早起的鸟儿有虫吃。”（直接引语是谚语）→ My teacher tld us yesterday that early birds catch wrms.昨天老师告诉我们早起的鸟儿有虫吃。（变成间接引语时态不变）
His friend said t him, “We are planning t have a picnic.”他的朋友对他说：“我们计划去野餐。”（直接引语为现在进行时）→ His friend tld him that they were planning t have a picnic.他的朋友告诉他说，他们计划去野餐。（间接引语为过去进行时）The rganizer said, “We have begun ur plan.”组织者说：“我们已开始了我们的计划。”（直接引语为现在完成时）→ The rganizer said that they had begun their plan.组织者说，他们已开始了他们的计划。（间接引语为过去完成时）
三、指示代词、时间状语、地点状语及方向性动词的变化
She asked, “Is this bk his?”她问：“这本书是他的吗？”（直接引语中用this）→ She asked whether that bk was his.她问那本书是不是他的。（间接引语中改为that）“I’ll be very busy tday,” said the man.那个人说：“我今天会很忙。”（直接引语中用tday）→ The man said he wuld be very busy that day.那个人说，那天他会很忙。（间接引语中改为that day）
四、连接词的选择1. 直接引语是陈述句，变为间接引语时，常变成由that引导的宾语从句。在口语中，that可以省略。He said, “I am very happy t help yu.”→ He said (that) he was very happy t help me.2. 直接引语是一般疑问句、选择疑问句或反意疑问句时，间接引语中用whether (或 nt) 或if引导。He said, “Are yu interested in English?”→ He asked (me) if/whether I was interested in English.【注意】如果主句中谓语动词是said，则将其改为asked。
四、连接词的选择3. 直接引语为特殊疑问句时，间接引语仍用原句中的特殊疑问词来引导，其余的变化遵照直接引语和间接引语之间的转换规则来进行。“What’s yur name?” he asked me.→ He asked me what my name was.“Where is yur textbk?” the teacher asked me.→ The teacher asked me where my textbk was.【注意】疑问句的直接引语变间接引语时，要把疑问语序变成陈述语序。
五、直接引语为祈使句时的变化直接引语为祈使句变间接引语时，要根据说话人的情感和语气使用ask、invite、advise、warn、tell、rder等词，再把祈使句的动词原形变为带t的不定式。如果祈使句为否定式，在不定式前加nt。He said t me, “Dn’t be late tmrrw.”→ He tld me nt t be late the next day.The fficial said, “Get ready befre lunch.”→ The fficial rdered us t get ready befre lunch.
