The teenage year from 13 to 19 were the most difficult time for me. They were also the best and worse years in my life. At the first, I thought I knew everything but could make decisions by myself. Besides, my parents didn’t seem to think so. They always tell me what to do and how to do it. At one time, I even felt my parents couldn’t understand me so I hoped I could be freely from them. I showed them I was independent by wear strange clothes. Now I am leaving home for college. At last, I will be on their own, but I still want to have my parents to turn whenever I need help. I was reading an article in a book while I came across a word I didn’t know. “Dad, what is the meaning of the word?”My dad, as he usual did after work, was watching his most favorite show. “You have the dictionary, don’t you?”he shot back. He didn’t even look up my face. I went back my room, and there on my study table is that dictionary. I looked it up and found it’s exact meaning. Ten year have passed and I still use that dictionary, along with the lesson I received earlier in life from my old man: to be independent.
高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she.

Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought

高中英语语法之情态动词 （一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。 （二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词 的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 He could be here soon. 他很快就来。We can't carry the heavy box. 我们搬不动那箱子。 I'm sorry I can't help you. 对不起，我帮不上你。 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则 有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought to 和used to看做是固定词组的话，那么，所有情态动词无一例外地只能接不带to的不定式：We used to grow beautiful roses. I asked if he would come and repair my television set. 2）情态助动词在限定动词词组总是位居第一：They need not have been punished so severely. 3）情态助动词用于第三人称单数现在时的时候，没有词形变化，即其词尾无-s形式： She dare not say what she thinks. 4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词： Still, she needn't have run away. 5）情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合，情态助动词的现在 时和过去时形式都可以表示现在、过去或将来时间：Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6）情态助动词之间是相互排斥的，即在一个限定动词词组中只能出现一个情态助动词，但 有时却可以与have和be基本助动词连用：You should have washed the wound. Well, you shouldn't be reading a novel. （三）情态动词有四类：①只做情态动词：must,can(could),may(might),ought to ②可做情态动词又可做实义动词：need,dare ③可做情态动词又可做助动词：shall(should),will(would) ④具有情态动词特征：have(had,has) to,used to ⑤情态动词表猜测 （四）情态动词的基本用法 1. can (could) 1）表示能力，could主要指过去时间。 Two eyes can see more than one. 两只眼比一只眼看得清。 Could the girl read before she went to school? 这女孩上学前能识字吗？ 2）表示可能（理论上或是逻辑判断上）。 The temperature can fall to –60℃, that is 60℃ below freezing. 气温可降至—60℃，也就是零下60℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′
高中英语必修三 情态动词（unit 1 ，unit 2） 一、情态动词的特点: 1.没有人称和数的变化。 2. 有些情态动词有过去式的变化: e.g. will → would , can → could , may→ might ,dare → dared 二、情态动词的否定式: 情态动词+ not +动词原形can not: can't , must not: mustn't , need not : needn't 三、情态动词的用法及相互区别, 是考试的内容之一 1. can , be able to be able to 表示经过努力后, 能够做到; be able to 有多种形式的变化。 can 1). 表示体力或脑力方面的能力; 2). 表示允许、可能性。 could 是can的过去式, 表示过去有能力及过去存在的可能性; 用于疑问句表示委婉地提出问题。 1) The fire spread through the hotel very quickly but everyone ____ get out.

高考情态动词(完整版) 一、单项选择情态动词 1．Look! There are so many mistakes in your composition. You ________ have fixed full attention on it. A．can B．should C．need D．might 【答案】B 【解析】 【详解】 考查情态动词。句意：看！你的作文里有那么多的错误。你本应该把所有的注意力都集中在它上面的。表示“本应该做但实际上没有做”应该用should have done结构，can have done 表示可能；need表示需要；might have done表示可能做过某事；故选B。 2．Most of the top leaders expressed a common desire at the UN conference, ______ that different cultures ______ coexist with tolerance. A．the one ; must B．the one ; should C．one ; must D．one ; should 【答案】D 【解析】 【详解】 考查替代和情态动词。句意：大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。替代表泛指的单数名词，通常用one替代。此处用one替代前面的a desire，是同位语；结合句意第二空用情态动词should“应该”。故选D。【点睛】 that ,it ,one 代指前面的名词时的用法 1.one 指代前面出现的可数名词，是泛指。可以和冠词连用，也可以有自己的定语。一般不能用做特指，但和定冠词连用时可以是特指。如： Please show me the cup, the red one on the shelf. 2.It 指代前面提到的单数名词，相当于the one。当one是泛指的时候，指的是同名异物，it是指同一物体.如： ----Do you want the cup ? ---Yes ,I want it. 3.that通常用来代替前面出现的可数名词\不可数名词,主要是用来避免重复。如： The weather of Guangzhou is hotter than that of Beijing. 3．Paul did a great job in the speech contest.
