高中英语知识归纳总结 一、句子成分 组成句子的各个部分叫句子成分。英语中句子成分有主语,谓语,表语,宾语,宾语补足语,定语,状语等。 在句子中的顺序一般是主语,谓语,宾语,宾语补足语,而表语,定语,状语的位置要根据情况而定。 1.主语 主语是句子主要说明的人或事物,一般由名词,代词,数词,不定式等充当。 Tom is good at playing football. 汤姆擅长踢足球。 2.谓语 谓语主要说明主语的动作,状态或特征。由动词(或短语动词)构成,可以有不同的时态,语态和语气。 We are studying English now. 我们现在正在学英语。 Page No.1387 3.表语 表语是谓语的一部分,它位于系动词be之后,说明主语的身份,特征,属性或状态。一般由名词,代词,形容词,副词,不定式,介词短语等充当。 We are Chinese. 我们是中国人。 4.宾语 宾语表示动作或行为的对象,跟在及物动词之后。能作宾语的有:名词,代词,数词,动词不定式等。 另外,有些及物动词可以带两个宾语,往往一个指人,一个指物,指人的叫间接宾语,指物的叫直接宾语。 He gave me a book. 他给我一本书。 有些及物动词的宾语后面还需要有一个补足语,意思才完整,宾语和它的补足语构成复合宾语。 We elected him monitor. 我们选他做班长。 Page No.1388 5.定语 在句中修饰名词或代词的成分叫定语。用作定语的主要是形容词,代词,数词,名词,副词,动词不定式,介词短语等。形容词,代词,数词,名词等作定语时,通常放在被修饰词的前面。 He is a new student. 他是个新生。 但副词,动词不定式,介词短语等作定语时,则通常放在被修饰词之后。 The bike in the room is mine. 房间里的自行车是我的。 6.状语 修饰动词,形容词,副词以及全句的句子成分,叫做状语。用作状语的通常是副词,介词短语,不定式和从句等。状语一般放在被修饰的词之后或放在句尾。副词作状语时可放在被修饰的词前或句首。 We will have the meeting in the big hall. 我们将在那个大厅里开会。 Page No.1389 7. 同位语 用于说明前面某一个名词或代词的内容的成分就叫同位语。通常由名词、名词词组、反身代词、同位语从句充当。 Tom, monitor of our class, is always doing well in the exam. 汤姆,我们班的班长,考试总是考得很好。 Page No.1390 二、句子种类 从句子的结构来讲,句子分为简单句,并列句和复合句三类。 (一) 简单句 由一个主语(或者并列主语)和一个谓语(或者并列谓语)所构成的句子叫简单句。简单句分为陈述句、疑问句、祈使句、感叹句四种。 1. 陈述句 凡是说明一件事情,指出看法,或者表达一种心情的句子是陈述句。陈述句分为肯定句和否定句。尤其注意由否定词构成的否定句;两者全部否定用neither或nor;两者的部分否定用not+both;三者以上的否定用none, nothing, nobody, no one等。 Page No.1391 Neither John nor Mary is here. 约翰和玛丽都不在这里。 Nobody agrees with what you said. 没有人同意你所说的话。 同时还要注意否定转移的情况,这类动词主要有think, believe, suppose, feel, expect等,但是hope不发生否定转移。 I don’t think he has time to play with me. 我想他没有时间和我玩。 I hope you weren’t ill. 我想你没生病吧。 Page No.1392 2. 疑问句 疑问句用以提出问题,按结构分为四类:一般疑问句,特殊疑问句,反义疑问句和选择疑问句。 (1) 一般疑问句:对某一情况是否属实提出疑问,一般用yes或no来回答,有两种形式: be/have+主语+其他? 助动词(情态动词)+主语+行为动词+其他? Page No.1393 (2) 特殊疑问句:用疑问词(what, who, how, why, when, where ...)提问,一般有两种结构:疑问词+一般疑问句型结构。 What are you doing? 你正在做什么? 疑问词作主语或主语的定语时用陈述语序。 What is your name? 你叫什么名字。 (3) 反意疑问句:表示提问者有一定的主观看法,但没有把握,希望对方来证实;有四种形式:前肯定后否定、前否定后肯定、前后都肯定、前后都否定,较为常用的有两种:前肯定后否定、前否定后肯定。 Page No.1394 注意: ①反意疑问句的回答应该以事实为依据,而不能依照中文的习惯回答。 —He isn’t a student, is he? 他不是一名学生,是吗? —No. He isn’t.(是啊,他不是学生。) /Yes. He is.(不,他是个学生。) ②注意反意疑问句否定提前时的情况。 I dont think he is honest, is he? 我认为他不诚实,是吗? ③一般来说句子里包含表示否定的副词,反意疑问部分选用肯定式; 如果包含的是表示否定的动词则不遵循此规则。 He has never been to the US, has he? 他从来没到过美国,是吗? He dislikes such a man, doesn’t he? 他不喜欢像这样的人,是不是? Page No.1395 ④在并列句中,反意疑问句部分要和第二个分句保持一致。 She isn’t a diligent student, for it is the third time that she has been late for school, isn’t it? 她不是一个勤奋的学生,因为这是她第三次迟到了,是不是? ⑤反意疑问句的构成形式为:主语+表示想法的状态动词+宾语从句,如果主句主语为第一人称,反意疑问的为宾语从句的主语;如果主句的主语为二、三人称,那么反意疑问的为主句的主语。 I don’t think he is lazy, is he? 我认为他不懒惰,是吗? Page No.1396 You all know that he is honest, don’t you? 你们都知道他诚实,是不是? 注意:英语口语中常用句型: (主语)祈使句 ...等+will you?往往表示一种建议、命令、恳求等,与反意疑问句有点相似。 You clean the floor today, will you? 今天你擦地,好吗? Those boys over there please come here, will you? 那边的那些男孩来这里,好吗? (4) 选择疑问句:形式上与一般疑问句相似,但里面包含两个答案,用“or”连接,不能简单地用yes/no回答。 Are you from Scotland or England? 你是来自苏格兰还是英格兰? Page No.1397 3. 祈使句 祈使句表示请求、命令、叮嘱、号召等,谓语动词用原形。当说话对象是第二人称时,一般省略主语,但如果要特别强调对方或表达某种情绪时可以有主语或加称呼语。若说话对象是第一人称或第三人称时,常用“Let+宾语+动词原形”。 Don’t be careless! 别粗心大意! You be quiet! 你给我安静点! Let’s go now, shall we? 让我们现在走吧,好吗? Let us go now, will you? 我们现在走吧,怎么样? Page No.1398 4. 感叹句 感叹句表示喜怒哀乐等情绪,句末用“!”;多用what或how引起:what用来修饰名词;how用来修饰形容词、副词或动词。 What a beautiful park it is! 那是一个多么美丽的公园呀! How beautiful the park is! 那个公园多美呀! Page No.1399 (二)并列句 包含有两个或更多互不依从的主谓结构的句子,就是并列句。并列句的分句通常由一个并列连词来连接。 常见的并列连词有and, but, though, however, while, or, for, so, therefore, not only ...but also ..., either ...or ...等。 It is raining outside, so we will stay at home. 外面正在下雨,因此我们待在家里。 He couldn’t go to school, for he was poor. 他不能去上学,因为他很穷。 Jane was dressed in brown while Mary was dressed in blue. 珍妮穿着棕色的衣服,而玛丽穿的衣服是蓝色的。 Page No.1400 (三)复合句 如果一个句子包含两个或者更多的主谓结构,其中一个(或更多)主谓结构充当句子的某一(些)成分,就是复合句。充当句子成分的主谓结构称为从句,从句只能是句子的一个成分,不能独立,常由从属连词引出,总是用陈述语序。根据从句在句子中的作用,可分为名词性从句,形容词性从句(定语从句)和副词性从句(状语从句)三类。 Whether she will come or not is still a question. 她是否会来仍是个问题。 Page No.1401 The question is who can complete the difficult task. 问题是谁能完成这个困难的工作。 Do you know who (whom) they are waiting for? 你知道他们在等谁吗? Page No.1407 在句子中起名词作用的从句叫名词性从句 (Noun Clauses)。 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语等,因此根据它在句中不同的语法功能,名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。其关联词有连接词that,if,whether;连接代词who,whom,whose,what,which,whoever,whomever,whatever,whichever;连接副词when,where,why,how等。 名词性从句 Page No.1408 一、主语从句 作句子主语的从句叫主语从句。that在句中无具体词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义,又起连接作用,在从句中充当从句的成分。 What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。 Whoever breaks the law should be punished. 任何违法的人都要受到惩罚。 Page No.1409 有时为避免句子头重脚轻,常用it代替主语从句作形式主语置于句首,而把主语从句置于句末。常用句型如下: (1) It+be+名词+that从句 (2) It+be+形容词+that从句 (3) It+be+动词的过去分词+that从句 (4) It+不及物动词+that 从句 It is a pity that he cant come to my birthday party. 很遗憾,他不能来参加我的生日晚会。 二、宾语从句 用作宾语的从句叫宾语从句,在句中可以作及物动词或介词的宾语。由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但若从句是并列句时,第二个及后面分句前的that不可以省略。宾语从句要使用陈述语序。 The report shows (that) we are making some progress but that we need to make grater efforts. 这份报告表明我们正在取得一些进步,但还需要作出更大的努力。 I want to know what he has told you. 我想知道他告诉了你什么。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。 She will give whoever needs help a warm support. 凡是需要帮助的人,她都会给予热情的支持。 注意:如果宾语从句后还有宾语补足语,则要用it作形式宾语,而将宾语从句后置。 He has made it clear that he will not give in. 他清楚地表明他不会屈服。 Page No.1411 三、表语从句 在句中作表语的从句叫表语从句,表语从句位于连系动词之后。 The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That’s just what I want. 这正是我想要的。 This is where our problem lies. 这就是我们的问题所在。 It looks as if it is going to rain. 看上去要下雨了。 需要注意的是,当主语是reason时,表语从句要用that引导而不是because。 The reason why he was late was that he got caught in a traffic jam on the way. 他迟到的原因是在路上遇到了交通堵塞。 Page No.1412 四、同位语从句 同位语从句跟在一个名词之后,对该名词的具体内容作进一步解释说明。后跟同位语从句的常见名词有:advice, demand, doubt, fact, hope, idea, information, message, news, order, problem, promise, question, request, suggestion, truth, wish, word等。 The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。 I have no idea when he will come back home. 我不知道他什么时候回来。 The thought came to him that Mary had probably fallen ill. 他想到玛丽可能生病了。 Page No.1413 五、注意以下几个问题: 1. whether与if 都可当“是否”讲时,在下列情况下一般用whether,不用if: 1) 引导主语从句并在句首时; 2) 引导表语从句时; 3) 引导从句作介词宾语时; 4) 从句后有“or not”时; 5) 引导同位语从句时; 6) 后接动词不定式时。 Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。 The question is whether she will accept our offer. 问题是她是否会接受我们的提议。 Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。 I cant decide whether to stay. 我不能决定是否留下。 Page No.1414 2. that引导同位语从句和引导定语从句的区别 that引导定语从句时,充当句子成分,具有双重作用,在从句中作宾语时可以省略; that引导同位语从句时,只起连接作用,没有词汇意义,不充当句子成分,一般不能省略。 试比较下面两个例句: I had no idea that you were here.(that引导同位语从句,不能省略) 我不知道你在这里。 Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句,作宾语,可以省略) 你通过这本书对古希腊人的生活了解了吗? 定语从句是中学英语学习的主要语法内容之一,也是高考英语的常考知识点。在历年的高考试题中,相对集中地考查了非限制性定语从句、关系代(副)词的用法、语义重复、主谓一致及“介词+which(whom)”等有关定语从句的知识。 Page No.1421 定语从句常见考点 一、非限制性定语从句 非限制性定语从句是高考试题中出现频率最高的考点。 1.引导非限制性定语从句时,可以用引导词which(但不可以用that)。 三、“介词+关系代词(which /whom)”引导的定语从句 In the office I never seem to have time until after 5:30 pm ,many people have gone home. A.whose time B.that C.on which D.by which time 解析:选D。by which time即:by“after 5:30”(到五点三十分以后)。介词的选择,取决于这个介词与先行词或从句之间的关系。又如: Lei Feng, from whom we have once learned a lot,is now an example to the soldiers of West Point Military School(西点军校)of America. 关系代词前面的介词from,与从句中的谓语动词learn构成习惯表达learn from(向……学习)。 四、语义的重复 He made another wonderful discovery, of great importance to science. A.which I think is B.which I think it is C.which I think it D.I think is 解析:选A。选项B重复了宾语it,因为关系代词which是think的逻辑宾语;此外,引导非限制性定语从句的连词不能省略,故选项D也不正确。 Page No.1425 五、“介词+whom”引导的定语从句与 who /whom引导的宾语从句作介词宾语时的区别 定语从句难点分析 定语从句是高中阶段的重点语法项目之一。因此,有必要全面弄清其用法。定语从句从句型上讲,它与以下六种句式相似,十分容易混淆。为了分清定语从句与这六种句型的差异,现将其分类例析如下: 一、定语从句与并列句 用一个恰当的单词完成下列句子,使之完整与正确。 ①Mr Li has three daughters,none of is an engineer. ②Mr Li has three daughters,but none of is a dancer. ③Mr Li has three daughters; are doctors. 定语从句与并列句的主要区别在于:并列句有and,but,so等并列连词或两个句子用分号连接,这时就不能再用引导定语从句的关系词了。从结构上看,①小题是定语从句,故填whom;②小题有并列连词but,是并列句,故填代词 them;③小题是两个并列分句,无需连接词,缺少主语,故填none或they。 Page No.1428 二、定语从句与地点状语从句 用一个恰当的单词完成下列句子,使之完整与正确。 ①Rice doesnt grow well there is not enough water. ②I still remember the farm my parents worked ten years ago. 定语从句与地点状语从句的主要区别在于:定语从句有表示地点的先行词,而地点状语从句则没有;定语从句的关系词根据需要可以用“介词+which”来代替where,而地点状语从句则通常只能由 where引导。因此,从结构上看,①小题无表示地点的先行词,故为表示地点的状语从句,填where;②小题中the farm是先行词,是定语从句,故填where,此处的where可以用on which替换。 Page No.1429 三、定语从句与强调句 用一个恰当的单词完成下列句子,使之完整与正确。 ①It is on the morning of May 1st I met Liang Wei at the airport. ②It is the factory Mr Wang works. 定语从句与强调句的主要区别在于:强调句的结构为“It is/was+被强调部分+that+从句”。被强调部分可以是除谓语以外的任何成分,当被强调部分是人时,还可用who代替that。在这个句型中,一定不能因为被强调部分是表示时间或地点的词就用when或where代替 that。从结构上看,①小题是强调句,故填 that。此种情况检测的标准是:先把强调句中的It is/was that去掉,再把被强调部分还原,在不增加或减少任何单词的情况下,如果句子仍然成立则为强调句,否则为定语从句。将第①小题改为:I met Liang Wei on the morning of May 1st at the airport.显然,这句话是正确的,故为强调句。②小题则是定语从句,用上述方法转换便知the factory前缺少一个介词in,故填 where。 Page No.1430 四、定语从句与结果状语从句 用一个恰当的单词完成下列句子,使之完整与正确。 ①I have the same computer you have. ②She is such a kind and funny girl all of us like to make friends with her. 定语从句与结果状语从句的主要区别在于(这里只讨论the same ...as/that和such ...as/that两种情况):在这两种情况下,如果as/that既引导从句,同时又在从句中充当一定的成分,则as/that引导的是定语从句。在the same...as/that结构中,用as指同样的,但不是同一个事物;用that指同一物品,故①小题填as;如果as/that在从句中不作任何成分,只起连接作用,则as/that引导的是结果状语从句,故②小题填that。 Page No.1431 五、定语从句与习惯句型 用一个恰当的单词完成下列句子,使之完整与正确。 ①It is the first time she has been to Shanghai. ②It was the time Chinese people had a hard life. 这里①小题是一个习惯句型,其结构为:It is/was the first/second ... time +that从句。故①小题填that。句意为:这是她第一次来到上海。②小题的the time是先行词,其后是表示时间的定语从句,故填 when。 Page No.1432 六、定语从句与简单句 用一个恰当的单词完成下列句子,使之完整与正确。 ①The mother told the lazy boy to work, didn’t help. ②The mother told the lazy boy to work. didn’t help. 含有定语从句的复合句与简单句的主要区别在于:前者有主句,有从句,必须有关系词;而后者则是两个单独的句子,不需要任何关联词。①小题两个句子用逗号连接且没有并列连词,显然应该是主从句关系,因此需用关系词which引导,前面整个句子作先行词;②小题则填It,代替前面的整个句子。解题时,要注意标点符号的运用。 1. 时间状语从句 常见的连词(组): when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副(介)词(短语)或名词短语: directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下: (1) when, while, as引导的时间状语从句 as表示“当……的时候”,往往和when/ while通用,但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候,又可以表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间,仅表示从句和主句的动作同时发生,并且有延续意义,该从句中的动词一般要用延续性动词,从句中常用过去进行时态或一般过去时态;当when表示a period of time时,两者可以互换。 She came up as I was cooking.(同时) 在我做饭时,她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时,每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视,而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。 ( 不可用as或when,这里的while意思是“趁……”) Page No.1440 (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才,要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasnt long before he told me about the news. 没多久他就告诉了我那条新闻。 ② 不等……就……;
