範例五：工件進入時間間隔為平均30分鐘的指數分配，之後進入一個工作站以打上標籤Label(設打標籤沒有時間延遲)，並指定Label＝ 1。之後進入一個Queue for machining然後進入Machining工作站接受加工。Machining工作站的加工時間為平均10分鐘，標準差2.5分鐘常態分配。加工完畢，進入Queue for Test之後進入Test工作站接受檢測。Test工作站的檢測時間為平均10分鐘，標準差2.5分鐘常態分配。出了Test工作站，有80%的機率為良好，直接走到出口Unrepaired，有20%的機率為不良品，要走到failed items然後進入一個工作站將Label的值改設定為2(設打標籤沒有時間延遲)，之後走進Queue for Machining，然後再走進Machining 工作站接受重新加工。Machining工作站以Routing Out功能，依照Label的數字將工件分流。如果Label＝1，則工件走向Queue for Test，表示工件沒有經過重工。

若Label ＝ 2，則工件走向Queue for Repair之後進入Repair工作站，再延遲平均10分鐘指數分配，然後走向出口Repaired。

主系表结构(讲义及解析)

主系表结构（讲义及解析） Part 1——主系表结构的分类 系动词的分类： 状态系动词，感官系动词，变化系动词，保持系动词。 主系表结构根据以上四个系动词也分为相应的四类。〔七上只涉及到前两类：状态系动词和感官系动词的主系表结构〕 【一】主语+状态系动词〔be〕+表语 1．主语+ be+表语——含义 be 动词和表语一起说明主语的状态和性质等I am a teacher． The students are in the classroom． Our classroom is big． 2．主语+ be+表语——句式变换The dress is reD、 否定句：The dress isn’t reD、一般疑问句：Is the dress red? 肯/否定回答：Yes，it is．/ No，it isn’t．对划线部分提问：What col or is the dress? 【二】主语+感官系动词+表语 1．感官系动词 look 看起来sound 听起来smell 闻起来 taste 尝起来feel 摸起来 2．感官系动词+形容词eg：That sounds gooD、 It looks beautiful． The sweater feels soft． Part 2 ——例题与练习 例题部分 1．琳达是一个聪明的女孩。〔翻译〕

五种基本句型-主系表结构

五种基本句型——主系表结构 主（语）＋系（动词）＋表（语） 主语，主语是五种基本句型都具备的。 从位置上来看，主语一般在句子开头，也就是一个句子的“头把交椅”。 从意义上理解，主语一般是一个句子的“陈述对象”，后面的一切都是针对主语来说的。 主语一般是名词或代词（当然还有其他，这里暂且详细讨论） 系动词是联系动词的简称，顾名思义，它是起到联系作用的动词，是连接主语和表语的。系动词的数量是有限的，常见的只有十来个，我们把它们分成四组，这 样有助于我们记忆系动词： 一、be动词类：am、is 、are 、was 、were 二、表示变化类：become、get 、turn 、grow 、go 三、感官动词类: 眼（look ）耳(sound)鼻(smell)舌(taste)身(feel) 四、表示延续性的动词：remain 、stay 、keep 表语 从位置上来讲，它总是在系动词后面（系动词和表语关系甚为紧密，没有系动词，就没有表语：没有表语，就没有系动词。 二从意义上讲，表语通常是来说明主语的性质、特征的。表语通常是由形容词、介词短语、名词、代词、动词不定式、doing 等来充当。 上面就是对主系表结构的简要介绍，其中，系动词是主系表结构的核心，它是这个结构的标志，看到了系动词，也就能立刻判断出句子的结构是主系表，因此， 记住系动词非常重要。

练习 找出下面句子中的主语、系动词及表语，并指出主语和表语分别是由什么词性或词类来充当的。 1 Tom is a student. 2 He is fat. 3 I am tired . 4 We are students. 5 The bag was lost . 6 The boy was foolish . 7 They were kind. 8 She is in the room. 9 The books are on the desk. 10 Snow is white. 11 Kate was here yesterday. 12 My father became a teacher in 1978. 13 The weather gets hot in summer. 14 She looks beautiful. 15 The flower smells good. 16 We were very happy. 17 You are right. 18 The soup tastes delicious. 19 The chair is yours. 20 The children are asleep. 21 The story is interesting. 22 He feels better today. 23 The leaf turns green. 24 I stayed awake all the night. 25 The weather still remained cold in April. 26 The little girl is six. 27 My work is to look after the baby.

英语基本句型之一：主系表结构

英语基本句型讲练 1. 主系表结构：主语+系动词+表语 Link verbs: be, look, feel, sound, seem, taste, smell, become, go, turn, get, grow, prove, fall, keep, remain, stay, lie, stand, turn out e.g. 1) Smith is a boss/over 40/ smart/ in a room/ to go to see a film/ excited/out 2) Her job is looking after the baby. 3) This dictionary is not hers but mine. 4) She looks happy/ felt happy/ fell ill/ went mad. 5) It is no use/ useless doing it now. 2. Exx.(高考书面表达P6) Grammar Link verbs 系动词又叫连系动词：它是中学英语中的重要语法项目之一，也是历届高考考查重点和热点。 I：用法 连系动词本身有一定的词义，但不能独立作谓语，必须与表语一起构成谓语。表语通常由名词、形容词，或相当于名词或形容词的词或短语等充当，说明主语是什么或怎么样。 II：分类 英语中最常用的连系动词有20个左右，一般分为四类： 1：“存在”类：表示存在或具有某种特征或状态。这类连系动词强调“存在”。 常见的有：be (是)，seem(似乎是)，appear(似乎、显得)，prove (证明是) 等。 例如： You are a student, aren’t you?你是学生，对吗？ He is very disappointed with the results of his examinations.他对考试结果很失望。 Who looks after your dog while you are out? 你不在家谁来照料你的小狗？ The theory he stuck to proved (to be) correct.他所坚持的理论证明是正确的。

系表结构的几种常见句型

系表结构的几种常见句型 陕西汉中市委党校王珂 在英语中，有一类句型是由系动词加上主语补足语或表语构成。这种句式也叫做系表结构。在教学中，发现许多同学对系动词后究竟跟什么，迷惑不解。本文特把系表结构中的几种句式归纳如下。 在英语中，系动词根据其意义大致可以分为两类:第一类表示具有某种特征或处于某种状态,如appear,be,keep,lie,look,prove,remain, rest,ring, seem,smell,sound,stay,tast等.第二类表示由某种状态变为另一种状态, 如become,come,fall,get,go,grow,run,turn等。 1．系动词后的表语是名词或代词，表示主语的身份、属性，也可以是数词，表示主语的数量、年龄或顺序。 (1)She has become a teacher . 。她已成为一名教师。（表身份） (2)The cup which he is using is mine . 他用的那只杯子是我的。（表属性） (3）My cousin is 22 years old 我的表妹22岁。（表年龄） 2．系动词后的表语是形容词、副词或介词短语，表示主语的性质、特征或状态。如 (4)He looks quite young . 他看起来相当年轻。 (5)All their efforts to solve the problem proved useless 他们为解决这个问题所作的努力都证明没有什么效果。 [注意] 表语为形容词时，则可用of加该形容词相应的名词构成的介词短语来代替。. (6)The point under discussion is very important .=the point under discussion is of vital important . 正在讨论的问题极为重要。 3．系动词后的表语是不定式，其主语通常由抽象名词，不定式或从句表示。 (7)My idea is to do it today . 我的意见是今天就干。（主语是抽象名词）

主系表结构完整归纳

主系表结构 句型SVSC(1) 主语+be+表语（句词/代词）用法在本句型中，名词或代词作表语，名词或代词可带附加成分，要注意主谓一致和时态问题 佳句背诵I’m a college student. It must be a grammar mistake. ①人类居住的唯一家园是地球。The only home for man to live on is the earth. ②失败乃成功之母。Failure are the mother of success. ③所有这些词典都对我帮助很大。All these dictionaries are great help to me. ④门口那辆摩托车不是我的。The motorcycle at the gate is not mine. ⑤倘若我是你，我就采纳他的建议。If I were

主系表结构

浅析主系表结构 英语句子简单句共有5种结构，主系表是其中的一种，也是学生最不易掌握的一种，为了让学生更好地理解和运用这一结构，我们可以从以下几个方面来入手： 一、结构：S+V+P S指句子的主语，V代表系动词，P指用来表明主语身份，状态或情况的表语。在掌握此结构时需强调两点：1．系动词．能用于主系表结构的系动词除了be动词外还有11个，可以按四三二一一模式来记忆，四即四个感官动词：look, sound, smell, taste ; 三是三个变得：get ,turn, become ; 二指的是两个保持：keep，stay ; 再加一个seem, 一个feel . 2．表语．学生在初学时往往搞不清什么是表语，因为汉语当中没有表语，表语它指的是用于表明主语身份，状态或情况的句子成份，它可以由形容词，名词，副词和介词短语来充当。 二．用法：S+V+P主要用来表明主语的身份，状态，特征以及所处的位置。具体说来如下三类汉语句子应该用S+V+P来译。 （1）主语是什么。e.g: I am a teacher. You are a student. （2）主语怎么样。e.g: She is beautiful. I am handsome. （3）主语在何处。e,g: We are at home. Kangkang is in Beijing. 三．S+V+P的各种句式变换。 【1】主语+be+表语这类句子句式变换时瞄准be动词就行了，变否定句时在be动词后面加not,变疑问句时将be动词与主语交换位置并调换大小写及标点符号即可，特别提醒句中人称一改二。 e.g: I am Mary. 否定句：I am not Mary. 疑问句：Are you Mary? 答： Yes,I am. No,I am not. 【2】主语+除be外的其它系动词+表语这类句子要变换句式时要借助助动词do,变否定句时do和not缩写为don’t放在系动词前，其它的照搬，变疑问句时do放句首，人称一改二，句号变问号。如果主语为三单时借does与not缩写为doesn’t放在系动词前，系动词还原，变疑问句时does置于句首，系动词还原，句号变问号即可。 e.g: I look nice today. 否定句：I don’t look nice today. 疑问句：Do you look nice today? 答语： Yes,I do. No,I don’t. The chicken smells very delicious. 否定句：The chicken doesn’t smell very delicious. 疑问句：Does the chicken smell very delicious? Yes,it does. No, it doesn’t. 总之，主系表结构的句子在简单句中及其常见，希望各位英语教师务必引起高度重视。
