You(He, She, They) will go.I(We)shall(will) not go. You(He, She, They)will not go.Shall I(we) go? Will you (he, she, they) go? 用”be going to +动词原形”也可表示将来时,表示将要发生的事,打算或决定要做的事。 b)一般将来时的用法:1)表示将要发生的动作或情况;2) 不以人的意志为转移,肯定要发生的事情。The day after tomorrow will be National Day.后天是国庆日。 3. in/after:in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”,句子中的谓语动词要用一般将来时态;after常指以过去时间为起点的“一段时间之后”,所以它与过去时态连用。当after指某个特定的未来时刻或日期之后,或指以将来某一时间为起点的若干时间之后时,它可以与将来时态连用。 4.more, less, fewer的用法区别:more为many, much的比较级,意为“更多”,可修饰可数与不可数名词。Less是little的比较级,意为“更好,较少”,修饰不可数名词。Fewer是few的比较级,意为“更少”,修饰可数名词复数。 【注意】few, little表示否定“几乎没有”。a few, a little表示肯定“一点,几个”。 5.would like sth意思为“想要某物“; would like to do意思为”想要做某事“。回答would like句型的一般疑问句时,其肯定回答为 “Yes, please.”;否定回答“No, thanks”或 “I’d like /love to, but….” 6. Such作形容词,意思是“如此的”“这样的”,修饰各种名词。 Such这样的。如It is such bad weather.天气如此恶劣。 Such常和as搭配,表示一种类别。如We enjoy such a voice as hers.我们喜欢象她那样的嗓子。 Such常和表示结果的that从句搭配,表示“如此….以至于…”如 It was such a hot day that we all had to stay at home. Such…that…和so…that…都可用来引出一个结果状语从句。由于such是形容词,所以that从句前有一个受such修饰的名词;而so 是副词,用以修饰形容词或副词,因此that从句前一般不出现名词。如 They are such kind-hearted teachers that people in the village all respect them. The exam was so difficult that many students failed to pass it. 如果名词是可数名词的单数形式,such和so的位置不同: such+a/an+形容词+单数名词 so+形容词+a/an+单数名词 如果名词是不可数名词或名词复数,只可用such,不能用so.: such+形容词+不可数名词或复数名词 如果被修饰的不可数名词被much, little, 或复数名词被many, few等表示量的形容词修饰时,用so,不用such. 当little表示“年纪小的”时,可用such+little+名词。 7.be able to 为“能,会”,表示能力,在这个意义上与can的意思相同,一般情况下两者可以互换,但can只有现在式和过去式(could)而be able to则用于更多的时态,主要体现在be的变化。 两者在用法上有一些差异:can (could)表示主观能力不表示意愿,它的将来时用will be able to而 be able to表示主观意愿强调克服困难做某事。 【重点语法】 一般将来时 表示将要发生的动作或存在的状态。本时态标志词: 1.含tomorrow; next短语; 2.in+段时间 ; 3.how soon; 4.by+将来时间; 5.by the time sb.do… 6.祈使句句型中:or/and sb. will do 例Be quick, or you will be late=If you don’t be quick, you will be late 7.在时间/条件状语从句中, 如果从句用一般现在时, 主句用将来时 8.another day 比较be going to 与will: be going to 表示近期、眼下就要发生的事情,will 表示的将来时间则较远一些。 如: He is going to write a letter tonight. He will write a book one day. 2. be going to 表示根据主观判断将来肯定发生的事情,will表示客观上将来势必发生的事情。 He is seriously ill. He is going to die. He will be twenty years old. 3. be going to 含有“计划,准备”的意思,而 will 则没有这个意思,如: She is going to lend us her book. He will be here in half an hour. 4.在有条件从句的主句中,一般不用 be going to, 而多用will, 如: If any beasts comes at you, I'll stay with you and help you. 掌握了它们的这些不同,你就能很好的区分be going to与will了。 be going to do (动词原形)结构:表示打算、准备做的事情或者肯定要发生的事情。如:It is going to rain. will do 结构表示将来的用法: 1. 表示预见 Do you think it will rain? You will feel better after a good rest. 2. 表示意图 I will borrow a book from our school library tomorrow. What will she do tomorrow? 基本构成如下: 一般疑问句构成: (1)will+主语+do…? Will Sarah come to visit me next Sunday? (2)there be 结构的一般疑问句:Will there + be …? Will there be fewer trees? Yes, there will. / No, there won’t 否定句构成:will + not (won’t)+do Sarah won’t come to visit me next Sunday. 特殊疑问句构成: 特殊疑问词+will+主语+…?What will Sarah do next Sunday? 根据例句,用will改写下列各句 例:I don’t feel well today. (be better tomorrow) I’ll be better tomorrow. 1. Gina has six classes today. (have a lot of homework tonight) _____________________________ 2. I’m tired now. (sleep later) _____________________________ 3. My parents need a new car. (buy one soon) _____________________________ 4. We can’t leave right now. (leave a little later) _____________________________ 5. The weather is awful today. (be better tomorrow) _____________________________ 初二英语下册第二单元重点总结 一丶重点短语 1.argue v.争论;争吵 argue with sb.与某人吵架 I argued with my best friend.我和我的好朋友吵架了。 2.① either adv.(用于否定句)也 He doesn’t have any money, and I don’t, either.他没有钱,我也没有。 I can’t play chess.

We/You/ They were working. 否定式:I/He/She/It was not working. We/You/They were not working. 疑问式和简略答语:Was I working? Yes, you were. Was he working? No, he wasn’t. 【注意】was not常简略为wasn’t; were not常简略为weren’t e) 过去进行时的用法:过去进行时表示过去某一时刻或某一段时间正在进行的动作。这一特定的过去时间,f) 除有上,g) 下文暗示以外,h) 一般用时间状语来表示 not …until直到…才。表示动作在某时之前尚未开始,直到此时动作才开始。not…until可以用after或when来代替,但主句谓语动词要用肯定形式。Until为连词时后接时间状语从句,until作介词时,后面接表示时间的名词。Until 用于肯定句多表示动作或状态一直延续到until所表示的时间为止,意思为“直到…” from..till…中till往往表示不太具体的时间。From …to…或from…until常用来表示具体的时间。 find it…to do,it在此句中为形式宾语代表动词不定式,动词不定式为真正的宾语,常用于这种用法的动词有find, feel, think, make等。 “疑问词+不定式“结构相当于一个名词性从句,常常可用同等成分的从句代替。改写时,只需在疑问词后面加一个适当的主语(这个主语一般与主句的主语一致),并将不定式改成适当形式的谓语即可。如,Where to go is still a question.= Where we should go is still a question. when 与while:when连接的状语从句是个特殊句型,“前一个分句(谓语动词用过去进行时)+when(作并列连词,意思为“这时,突然”)+后一个分句(谓语动词用一般过去时)”表示在前一个动作正在进行的过程中突然发生了后一个动作, when强调动作的突然性,when后面的动词为非延续性动词;while表示“在….过程中”,强调在一段时间内,所以while引导的从句中的谓语动词必须为延续性动词。在状语从句中,若从句放在句首时,应用逗号与主句隔开。 感叹句的构成:What +a/an+形容词+单数名词+主语+谓语!What a good book it is! What+形容词+复数可数名词+主语+谓语!What easy questions they are! What+形容词+不可数名词+主语+谓语!What cold weather it is! How+形容词+主语+be动词!How nice the watch is! How +副词+主语+谓语!How hard they are working! 8.take place, happen“发生”:take place指“发生事先计划或预想到的事物”;happen指“一切客观事情或情况的偶然或未能预见地发生”。两者都是不及物动词或短语,后面不能跟宾语,也不能用于被动语态;happen的意义很广泛,而take place 仅用于历史上的事件,集会等,是先行布置而后发生或举行的事件,它不用于地震等自然界的现象。 happen to do 巧遇 sth happens to sb某人遭遇某事 9.不定代词all, both, each,every与not连用时,只表示部分否定,在否定句中用and连接两个宾语,表语,定语,状语时,只表示部分否定,并且否定 and后面的部分;如用or连接句中两个部分,则表示全部否定。如,She isn’t a bright and beautiful girl.她并不是一个既聪明又漂亮的女孩。(部分否定) She isn’t a bright or beautiful girl.她是一个既不聪明又不漂亮的女孩。(全部否定)。 四、重点练习 一、按要求改写句子,每空一词 1、I made a model house, She helped me.(合并成一句) 2、Which do you prefer, the big one or the small one?(保持原句意思) 3、There is a lot of traffic on the street.(改为否定句) 4、The nearest shopping center is only 800 meters away.(就划线部分提问) 5、Don’t eat or drink in the classroom.(保持原句意思) 6、This sign tells us to turn left.(就划线部分提问) 7、At school we have rules to keep us safe.(就划线部分提问) 8、Let’s go to see the film.

(help) 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tomorrow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 one’s 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“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below. 达标训练 Ⅰ. 单词拼写 1.

Some magazines were given to him by us. 【注意】一般将主动句中表示人的间接宾语变为被动句中的主语。 主:主语+谓语+宾语+宾语补足语 被:主语(原宾语)+be+过去分词+原宾语补足语 如,They elected him their monitor.→He was elected their monitor. 【注意】如果主动句中宾语补足语是不带to的不定式,变成被动语态后一般要加to. I saw him go to the church.→He was seen to go to the church. 【扩展】一般在以下几种情形时,需要使用被动语态。 不知道动作的执行者,只知道动作的承受者时。 When we got there, the room had been cleaned already. 不必要说出或出于礼貌不便说出动作的执行者时。 I was told that you were not honest enough. 3)有必要突出或强调动作的承受者时。 You were asked to answer this question. 16.if与whether:if和whether均可用于宾语从句中,意为“是否”;if用于条件句中,表示“如果”,不能和or连用;whether常与or连用,表示两种条件或情况。 【扩展】if not..如果不是…,表示惊讶或憎恶等情绪;if only意为“若…那就好了,我多么希望…”相当于how I wish;only..if..意为“决不…除非…” If it hadn’t been for the doctor’s care, I should not be speaking to you now.如果不是医生的照顾,我现在就不会和你说话了。 If only he arrives in time!若他及时到达就好了。 I’ll only come if you promise me that you won’t invite Henry.除非你答应不请亨利,否则我不会来。 初二(八年级)下册英语第七单元知识点 依据初二(八年级)下册英语第七单元教材,总结了重点字词、词语的基本用法、同义词改写及典型试题的用法,适合初二学生学习英语、中考考生备考英语。 ☆重点归纳☆ 话题Make requests 功能项目Apologize 词汇mind 介意 not at all一点也不 turn down调低 yard院子 dish盘堞 brought bring 的过去式 line排;队 polite有理貌的 perhaps或许;大概 door门 voice声音 return归还;返回 term 术语Asian亚洲的;亚洲人的 Europe欧洲 impolite无礼的;粗鲁的 allow允许;承认 public公众 cough 咳嗽smoke抽烟,吸烟drop扔;丢 litter垃圾 pick…up 捡起 behavior 行为;举止 solution解答;解决办法 annoyed恼怒的;生气的 clothing衣服 normal正常的;正规的 etiquette礼节 sneeze打喷嚏;表现 politely客气的;斯文的 cigarette香烟;卷烟;纸烟 criticize 批判 careful 小心;当心 短语right away立刻;马上 at a meeting在开会 cut in line插队 the way to place 去…的路 spend sth.

The box is too big for me to carry.= The box is so big that I can’t carry it. 【注意】当动词不定式和主语在逻辑上构成动宾关系时,该动词后面不能再用it或them作宾语,该动词如果是不及物动词,则必须在其后面加上相当的介词或副词,方可与主语构成搭配。如,The ice is too thin for me to skate on. instead, instead of: instead为副词,在句中独立作状语,instead of为介词短语,后面一般接名词,代词,介词和接动词-ing形式。 for example, such as: for example例如,诸如。多作插入语,当它表示“例如“时,其后面必须有逗号;such as相当于like,意思为 “象…那样,例如,诸如”,其后面直接加名词。 contest, compete,contend三者都有“竞争”的含义,均为动词:contest指在竞争中毫无保留地展示自己;compete指在体育或辩论等需要竞争的活动中,为征服或取胜而进行的努力。有时暗指在奖赏的鼓励或刺激下进行竞争;contend暗示竞争的紧张程度。通常指双方成功的机会相等,所以为取胜或征服对方就需要艰苦的努力。强调奋斗或斗争的必要性。 contest,competition:contest指双方或多方对垒比赛,多指体育比赛,并且在比赛中的每一个人或每一个队都力图战胜对方;competition多指能力,技巧,知识等方面的比赛,竞争。 By的用法:by后跟表示交通工具的名词,意思为“乘,坐”;by意思为“凭借,用,靠”,表示方法或手段,常与v.-ing连用;by意思为“在…旁边”,用来表示地点,意义和用法近似于beside;by意思为“按照…,根据…”;by意思为“经过”,后常跟go, run, walk之类的动词;by用于被动语态中,后跟的名词表示行为的执行者,意思为“被,由”;by意思为“按…(计算)”,用来表示计量;by oneself独自;by the way顺便 as well的同义词为too,意思是“也”;as well as意思为“同,和,也”。用来连接名词和代词等。谓语动词用单数还是复数形式,要根据as well as前的名词或代词确定。与动词连用时,用v-ing形式;as well as同义词组为not only…but also…但侧重顺序不同。 初二(八年级)下册英语第九单元知识点 现在完成时表示发生或已经完成的某一动作对现在造成的影响或结果。通常表示短暂动作或位置转移的动词(非延续性动词,不能与表示一段时间的状语连用;也可以表示过去开始,一直延续到现在的动作或状态。也就上说,现在完成时虽与过去有关,但实际上强调的是对现在的影响或结果,句中谓语动词通常是延续性动词,且常与表示一段时间状语连用(these days,all this year, recently,for+时间段,since+时间点) 通常与现在完成时连用的几个副词:already,recently,just, ever,never,before,yet等。表示不确定时间的时间词连用。Already,just多用于肯定句;yet,ever,never多用于疑问句或否定句。 现在完成时的结构:主语+have/has+动词过去分词 have been to, have gone to:have been to“到过某地”说话时此人很可能不在那里,已经回来,侧重指经历;have gone to“已经去了某地”,说话时此人在那里,或可能在路上,反正不在说话现场。 neither开头的倒装句:在英语中“Neither+助动词/情态动词/+主语”这个倒装结构是一种否定形式,表示“两者都不”。如,I can’t work out the problem. Neither can Li Ming. be from, come from:两者都为“从…来,出自…”;表示“出身于…”,应用come from 【注意】问别人的出身或叙述自己的出身时,时态一定要用一般现在时,如果时态为一般过去时,则表示“从…地方来”。 7.Population的用法:1)population是个集合名词,意思为“人口,人数”,常用来指人口的总称。被看作一个整体时,一般不加-s,在句中作主语时,谓语动词多用单数形式。如,The population of China is about1,300,000,000. 2)如果指一个整体中有多少人数是干什么的时候,谓语动词要用复数形式,这时强调的是一部分人。如,Half of the population in that country are farmers.3)表示“…的人口”时,既可用“the population of+地名”,也可用“the population in +地点”,作主语中心词时谓语动词用单数形式。如,The population in Shenyang is about 8 million.4)表示某国,某城市有多少人口时,用have/has a population of…结构。如,New Zealand has a population of 3,800,000.5)对人口数量提问用what或what large.用large或big表示人口多,用small表示人口少。 8.If的用法:if引导的条件状语从句表示“如果…”。构成形式为“主句+一般将来时态+if从句+一般现在时态”,或“If从句+一般现在时态,主句+一般将来时态”;if还可以引导虚拟语气,表示假设的情况或是发生的可能性不大的情况,从句用过去的某种时态。 9.Sleepy,sleeping:sleepy可作表语或定语,意思为“想睡的,困的”,可用very 修饰;sleeping所修饰的名词可以是人也可以是物。 初二(八年级)下册英语第十单元知识点 反意疑问句: 1)反意疑问句的含义:当对所陈述的某种情况不确定而反问对方时,常用反意疑问句来表达。 2)反意疑问句的构成:陈述句+简略疑问句→前部分肯定陈述句+后部分否定疑问句;前部分否定陈述句+后部分肯定疑问句。 3)使用反意疑问句时的注意事项: a.前后两部分要在人称上保持一致。 b.时态要保持一致(或动词要保持一致) c.回答的一致性(特别注意中文翻译)。 注意:yes与no后面的回答部分要一致。 4)使用反意疑问句时的特殊情况: a.在祈使句后进行附加疑问句时,用will you表示请求。 b.在Let’s后面,常用shall we,表示征询意见。 c.在Let us…后面进行附加疑问时,用will you,这一点属于祈使句范围。 d 在英语口语中,I am 后面的附加疑问句部分常用aren’t I . e 由nothing作主语的句子,附加问句中人称代词用it.f.由nobody作主语的句子,附加问句中用they代替nobody g.如果陈述句部分主语是everyone,someone,anyone,no one等不定代词,其附加疑问句部分的主语可以用he,也可用they.h There be…后面的附加疑问句部分仍用there. i.s如果陈述句部分含有否定副词never,few,little等词时,则其附加疑问句部分用肯定形式。 J.反意疑问句要求用yes或no来回答,当陈述句部分为否定形式时,回答要特别注意两种语言的表达习惯的不同,注意根据实际情况前后保持一致。 cost, price:cost作名词时表示“费用”,通常指服务费,学习费,生活费或房租费等,price通常指具体物品的价格。询问价钱用how much来提问。 at lest:至少,最少。其中least为little的最高级,little的比较级为less; 无论如何 Prepare的用法: 1)prepare for为…做准备,相当于get ready for 2)prepare+名词+for +名词,意思为“为…准备…” 3)prepare+名词+to do sth意思为“为…而做准备。” 4)prepare to do准备做某事。查看更多
