方向性动词的变化
Difference:
Rules:Direct speech reprts the exact wrds f the speaker. Indirect speech reprts what a speaker said in ur wn wrds. If we want t change direct speech int indirect speech, we will change tenses, prnuns, and ther wrds when necessary. First, if a verb in qutatin marks is in present tense,change t crrespnding past tense; if a verb is in simple past tense, change t past perfect tense.Secnd, persn prnuns change accrding t the persn f the bject f the reprting verb. Third, adverbs that shw nearness in direct speech are usually changed int wrds that shw distance in direct speech.
直接引语和间接引语1. 基本概念（1）直接引语：直接引述别人的话，把它放在引号内，叫直接引语。（2）间接引语：用自己的话转述别人的话，叫间接引语。【点拨】直接引语变为间接引语时，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作相应的变化。
2. 人称的变化直接引语变为间接引语时，人称的变化遵循以下原则。（1）一随主：直接引语中出现的第一人称代词要按照引述动词的主语的人称变化。She said，“I wn’t be frustrated.” → She said that she wuldn’t be frustrated. 她说她不会沮丧的。（2）二随宾：直接引语中出现的第二人称代词要按照引述动词的宾语的人称变化，若引述动词后没有宾语，也可用第一人称。I tld Mary，“We will prtect yu frm infectin.” → I tld Mary we wuld prtect her frm infectin. 我告诉玛丽我们会保护她不受感染。（3）第三人称不更新：直接引语出现的第三人称代词一般不需要变化。She said t me，“They want t decrease the amunt f fat they eat.” → She tld me that they wanted t decrease the amunt f fat they ate. 她告诉我，他们想减少脂肪的摄入量。
3. 时态的变化直接引语变为间接引语时，如果主句是过去的某种时态，则间接引语的时态应相应向前推一个时态，如下所示： 一般现在时→ 一般过去时现在进行时→ 过去进行时现在完成时→ 过去完成时一般过去时→ 过去完成时过去完成时→ 过去完成时（不变） 过去进行时→ 过去进行时（不变） 一般将来时→ 过去将来时
【点拨】（1）如果直接引语中有明确的表示过去时间的状语，变为间接引语时，时态不变。My mther said t me，“The museum was cmpletely transfrmed in 2017.” → My mther tld me that the museum was cmpletely transfrmed in 2017. 我母亲告诉我，图书馆在2017 年被彻底改造了。（2）如果直接引语表述的是客观真理，变为间接引语时，时态不变。The gegraphy teacher said t us，“The earth travels arund the sun.” → The gegraphy teacher tld us that the earth travels arund the sun. 地理老师对我们说：“地球围绕太阳转。”
4. 指示代词、时间状语、地点状语和动词的变化（1）指示代词this → that these → thse He said t me，“This is the Schl Cmputer Centre.” → He tld me that was the Schl Cmputer Centre. （2）时间状语nw → then tday → that day this mrning/week → that mrning/week yesterday → the day befre yesterday mrning → the mrning befre next week → the next week/the fllwing weeklast week → the week befre tw days ag → tw days befre tmrrw → the next day/the fllwing day the day befre yesterday → tw days befre the day after tmrrw → in tw days’ time （3）地点状语here → there （4）动词cme → g bring → take
5 .句型的变化（1）直接引语是陈述句，间接引语用连接词 that 引导，that 可省略。His mther said t me，“Mr Harry in charge f the wrk. ” → His mther tld me that Mr Harry was in charge f the wrk. 他的母亲告诉我，亨利先生负责这项工作。（2）直接引语是一般疑问句，间接引语用 whether/if 引导，疑问语序变为陈述语序，谓语动词 say（said）改为 ask（asked）。Mr Tnny said t me，“Are yur injuries severe?” → Mr Tnny asked me if/whether my injuries were severe.托尼先生问我伤势是否严重。
（3）直接引语是特殊疑问句，间接引语用原来的疑问词引导，疑问语序变为陈述语序。Mary asked me，“When did the British prince becme infected with the disease?” → Mary asked me when the British prince became infected with the disease. 玛丽问我这位英国王子是什么时候染上这种病的。（4）直接引语是祈使句，间接引语变为 ask/tell/rder sb.（nt） t d sth. 句式。He said，“Dn’t subscribe t her view.” → He tld me nt t subscribe t her view. 他告诉我不要同意她的观点。【注意】祈使句中的 please 在间接引语中必须省略。“Please pass me the pump，”he said t her. → He asked her t pass him the pump. 他请她把水泵递给他。
