not“或许不”；can表示推测时不用于肯定句，may表示推测时不用于疑问句。2.考查情态动词引起的一般疑问句的答语考点快忆 回答must时，肯定答语用must,否定答语用needn t或don t have to。回答need时，肯定答语用must,否定答语用needn t。回答may时，肯定答语用may，否定答语用mustn t 或can t。3.考查情态动词的意义考点快忆 must “必须”；have to“不得不”；need “必须；需要”；can(could)“能；可能”；may (might) “可以；可能”；shall，will (would)“将；会；愿意；要”；should“应当”。“had better (not) + 动词原形”表示建议；have to / has to had to的否定，疑问形式要借助于助动词do does did。四 There be 的句子结构There be是一个“存在”句型，表示“有”的意思，肯定句的形式为：There be + 名词（单数或复数）+地点状语或时间状语。be动词单复数的确定，看be后边第一个名词，当所接主语为单数或不可数名词时，be动词形式为is；当所接主语为复数名词时，be动词为are；当be动词后接两个以上主语时，be动词与最临近主语保持数上的一致。意思为“某地有某人或某物”。如：There is an eraser and two pensThere are two pens and an eraser（1）there be的否定句，即在be的后面加上not。否定形式为：There be + not + （any） + 名词+地点状语。There is not any cat in the room. 房间里没猫。There aren t any books（2）there be句型的疑问句就是将be提到句首：Be there + （any） +名词+地点状语肯定回答：Yes, there is / are. 否定回答：No, there isn t / aren t.-Is there a dog in the picture?画上有一只狗吗-Yes, there is. 有。-Are there any boats in the river?河里有船吗-No, there aren t. 没有。（3）特殊疑问句：How many . . . are there （+地点状语）某地有多少人或物回答用There be . . .There s有时直接就用数字来回答。One. / Two . . .-How many students are there in the classroom?教室里有多少学生-There s（4）如果名词是不可数名词，用：How much + 不可数名词 + is there + 地点状语How much water is there in the cup?杯中有多少水五中考对定语从句的考查：1定语从句的功用和结构在复合句中，修饰某一名词或代词的从句叫做定语从句。被定从句修饰的词叫做先行词。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如：This is the present that he gave me for my birthday2关系代词和关系副词的功用关系代词和关系副词用来引导定于从句，在先行词和定语从句之间起纽带作用，使二者联系起来。关系代词和关系副词又在定语从句中充当一个成分。关系待客做主语，宾语，定语，关系副词可作状语。1. 作主语：关系代词在定语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。例如：I dont like people who talk much but do little.The cars which are produced in Hubei Province sell very well.2. 作宾语：She is the person that I met at the school gate yesterday.The book that my grandmother gave me is called “The Great Escape”.3. 作定语关系代词whose在定语从句中作定语用。例如：Whats the name of the young man whose sister is a doctor?The girl whose father is a teacher studies very hard.4. 作状语Ill never forget the day when I first came to Beijing.三. 各个关系代词和关系副词的具体用法1. who 指人，在定语从句中作主语。例如：The person who broke the window must pay for it.The boy who is wearing the black jacket is very clever.2. whom指人，在定语从句中作宾语。例如：Do you know the young man (whom) we met at the gate？Mr Lee (whom) you want to see has come.3. whose 指人，在定语从句中作定语。例如：The girl whose mother is ill is staying at home today.I know the boy whose father is a professor.4. which指物，在定语从中作主语或宾语。例如：A dictionary is a book which gives the meaning of words.Here is the book (which) the teacher mentioned yesterday.5. that多指物，有时也指人，在定语从句中作主语或宾语。例如：Ive read the newspaper that(which) carries the important news.Who is the person that is reading the newspaper over there?6. when 指时间，在定语从句中作状语。例如：Ill never forget the time when we workedHe arrived in Beijing7. where 指地点，在定语从句中作状语。例如：This is the house where we lived last year.The factory where his father works is in the east of the city.四. 关系代词 whom， which 在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从句之间，有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写，而将介词置于定语从句的后面，如：That was the room in which we had lived for ten years. = That was the roomwhich we had lived in for ten years.五. 具体使用时还要注意下列问题：1. 只能使用that,不用which 的情况：(1) 先行词是all, few, little, nothing, everything, anything 等不定代词时。例如：All that he said is true.(2) 先行词被only, no, any, all,等词修饰时。例如：He is the(3) 先行词是序数词或被序数词修饰的词。例如：He was the second (person) that told me the secret.(4) 先行词是形容词最高级或被形容词最高级修饰的词。This is the best book (that) I have read this year.(5) 先行词既包括人又包括物时。例如：He talked about the people and the things he remembered.2. 只能用which，不用that 的情况：(1) 在非限制性定语从中。例如：The meeting was put off, which was exactly what we wanted.(2) 定语从句由介词+关系代词引导，先行词是物时。例如：The thing about which he is talking is of great importance.考查的主要形式是单项填空、完型填空、短文填空和完成句子。阅读理解和书面表达肯定也要用到定语从句。六宾语从句1.宾语从句的含义在整个句子中做宾语的从句叫做宾语从句。She knew that the teacher had seen the film.她知道这位老师看过这部电影。（“that the teacher had seen the film”做knew的宾语，同时又是由连接词that引导的从句，所以它叫做宾语从句。）2.宾语从句的分类（1）动词宾语从句：顾名思义，它是位于动词后面的宾语从句。He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。（2）介词宾语从句：顾名思义，它是位于介词后面的宾语从句。I agree with what you said just now.我同意你刚才说的话。（3）形容词宾语从句：顾名思义，它是位于形容词后面的宾语从句。I am afraid that I will be late.恐怕我要迟到了。3. 引导名词性从句的连接词（1）that：没有含义，在宾语从句中不做成分（2）whether/if：表示是否，在宾语从句中不做成分I dont know if/whether he still lives here after so many years.我不知道这么多年后，他是否还住在这里。（3）连接代词：what, which, who, whom, whose（在宾语从句中做主、宾、表和定语）连接副词：where, when, how, why（在宾语从句中做状语）The small children dont know what is in their stockings.（what 在宾语从句中做主语）这些小孩子不知道什么在他们的长筒袜里。Could you tell me why you were late for the meeting this morning?（why 在宾语从句中做原因状语）你能告诉我为什么你今天早上开会迟到吗？4. 在做宾语从句的题目时应注意两点（1）时态当主句是现在时态时，宾语从句可以根据需要使用任何时态。I dont know when he will come back.我不知道他将何时回来。He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。当主句是过去时态时，宾语从句必须是一种过去的时态。She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。He said that he could finish his work before supper.他说他会在晚饭前完成工作。当表示客观事实或普遍真理的句子做宾语从句时，任何时候都用一般现在时。The teacher said that the earth goes round the sun.老师说过地球绕着太阳转。（2）语序任何从句都使用陈述句语序，宾语从句当然也不例外。七被动语态被动语态由助动词be加及物动词的过去分词构成，助动词be有时态，人称和数的变化。被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be动词后面的过去分词不变。1. 各种时态的被动语态结构一般现在时的被动语态：主语am/is/are（not）过去分词一般过去时的被动语态：主语was/were过去分词现在完成时的被动语态：主语have/hasbeen过去分词一般将来时的被动语态：主语willbe过去分词过去将来时的被动语态：主语would/should+be过去分词过去进行时的被动语态：主语was/were+being过去分词过去完成时的被动语态：主语had+been+过去分词情态动词的被动语态：情态动词be过去分词2. 被动语态的用法（1）不知道或没有必要说明动作的执行者是谁，不用by动作执行者短语。Football is played widely all over the world.全世界都广泛地踢足球。（2）强调动作的承受者。The bank was robbed yesterday afternoon.昨天下午这家银行遭到抢劫。（3）作客观说明时，常采用一种被动语态句型。It is reported that about twenty children have died of flu in the USA.据报道美国大约二十名儿童死于流感。3. 主动语态的句子变为被动语态的步骤（1）把原句中的宾语变为主语（2）动词改为被动形式，即be+过去分词（3）原来的主语，如果需要的话，放在by后面；如果没必要，可省略。
