1、初二(八年级)下册英语第四单元知识点初二(八年级)下册英语第四单元知识点主要是依据初二(八年级)下册英语教材，从直接引语、间接引语、重点句型及达标练习总结了初二(八年级)下册英语第四单元知识点，适合初二学生学习英语、中考考生备考英语。知识点：在称述句中直接引语和间接引语的转换：a) 直接引语：说话人直接引用别人的原话。b) 间接引语：说话人用自己的话把别人的意思转述出来。c) 直接引语一般前后要加引号;间接引语不d) 用引号。e) 规则：1)人称变化：从句中的第一人称多改为第三人称;第二人称根据情况改为第一或第三人称;第三人称不f) 变。2)时态变化：如果主句的谓语动词是一般过去时，g) 直接

2、引语变为间接引语时从句的谓语动词在时态方面要做以下变化：直接引语 间接引语一般现在时 一般过去时(客观真理除外)一般将来时 过去将来时现在进行时 过去进行时如果主句的谓语动词是一般现在时，直接引语变为间接引语时，从句的动词时态保持不变;直接引语如果是客观真理变为间接引语时，时态保持不变。3)其他指示代词，时间状语，地点状语和动词等的变化。直接引语中的一些指示代词，时间状语和地点状语须作相应的变化：直接引语 间接引语指示代词 this这 these这些 that那 those那些时间状语 now现在 then那时today 今天 that day 那天tonight 今晚 that night那

3、天晚上this week 这星期 that week那个星期yesterday 昨天 the day before前一天last week 上星期 the week before前一个星期ago以前 before 以前tomorrow明天 the next/following day第二天next week 下星期 the next week 第二个星期地点状语 here 这里 there 那里动词 come来 go 去【注意】1)直接引语中的时间状语根据实际情况转述为间接引语时，有时不需要改变，如tomorrow。如果转述的动作发生在当天，无需改变;如果转述的动作不在当天，则需将tomorr

4、ow变为the next day.2.habit, practice, custom: habit指“个人由于自然条件，社会环境，爱好或经常接触而导致可以为常的行为或特性”;practice语气比habit弱，指“个人或大家都习惯了的做法或工作与生活的方式。”;custom指“经过一段时期在某人，地区或社会中形成的传统习惯或风俗。”3.bring, take, carry: bring指“从别处把东西或人带来”“拿来”，表示将人或物带到或拿到说话者所在的位置的这个动作;take指“把东西带走或拿走”，表示将人或物拿开或带离说话者所在的位置的这个动作; carry指“随身携带(不说明方向)有时含

5、有 “负担”的意思。4.Surprise用法：1)surprise作名词，表示“惊奇，诧异”;2)surprise作几物动词(后接某人作宾语)表示“使惊奇”;surprise的过去分词作表语，表示“感到惊奇”;to ones surprise表示“使吃惊的是”;be surprised at sth/sb表示“对感到惊奇”。5.however 与 but:两者均可作“但是，然而”，而且都引出并列分句。从语义上看，but所表示的是非常明显的对比，转折的意味较however要强;从语法上看，but是并列连词，而however却是连接副词;从语序上看，but总是位于所引出的分句前，而however却

6、可位于句首，句中和句末，但是译成汉语时一定要把它放在分句之首;从标点符号上看，but之后一般不使用逗号，而however则必须用逗号分开。However当连词用时，“无论以何种方式，不管怎样”，引导让步状语从句。6.first, at first与first of all：1)first可以做副词，意思是“首先，第一次，最初地”，指第一次做某事或首先做某事，first还可以用作形容词，意思是“第一的，最初的，主要的，一流的”，first作名词，意思是“首要，第一，最初”2)at first的意思是“起初，当初”，指刚刚开始做某事的时候，暗示后来的情况有所改变3)first of all的意思是

7、“第一，最初，首先”，同first的用法相同，但语气上比first要强，常常用来加强语气。7.true, real: true意思为“真的”“真正的”，强调与实际相符，而不是杜撰的，它与real相对。与to连用，意思是“忠实的”，true用作名词，与定冠词the连用，表示“真实，真理”等;real无此意。Real是形容词，强调客观存在的“真实”“实在”，不是想象的。8.above, on,over:三者都有“在上”之意。1)on表示两者上下紧贴在一起2)over表示一种直接的垂直概念，但没有上下紧贴的意思，反义词为under.3)above既不表示垂直的上下概念，也无相互紧贴的意思，反义词是b
