2、e sofa? No, it isn't.棒球在沙发上吗？不，不在。6. I don t know.【学海拾贝】 1. Where ' s my backpack?Where + be+主语（人或物）？是询问人或物在什么地方的句型。Where是表示地点的疑问副词，用来引导对地点提问的特殊疑问句。回答时，不用 yes或no,而要用表示位置的 介词短语来回答。当主语是单数时，be用is;当主语是复数时，be用are。例如：露茜现在在哪里？她在学校。Where is Lucy now? She ' s at school.我的钥匙在哪里？在抽屉里。Where are my k

3、eys? They are in the draw.思维拓展特殊疑问句是指以特殊疑问词引导的问句。其结构为：特殊疑问词+一般疑问句。特殊疑问词一般有 what, who, where, which, whose, how, how many, how much, whattime等等。X 那个人是谁？Who' s that man?X 这个背包多少钱？How much is this backpack?在练习题中，要求对划线部分提问就是将陈述句变为特殊疑问句。关键要选好与划线部分相应的特殊疑问词放在句首，然后将句子变为一般问句放在特殊疑问词后。X My book is under th

4、e table.(对划线部分提问)Where is my book?X There are 40 students in my class.(同上)How many students are there in your class? 2. It ' s under the table.(1) table意思是"桌子"，at the table意思为“在桌子旁边“；at table意思是“在 桌子旁边吃饭”。例如：孩子们都坐在桌子旁边。All the children are sitting at the table.孩子们正在桌子旁边吃饭。The children

5、are at table.(2) under the table 意思是“在桌子底下“。Under是介词，意思是“在，的下面“。 英语中表示某人或某物在某个地方，常用介词短语来表示。本单元我们所学的in, on, under都是介词，它们与名词构成介词短语来表示东西或人的位置。特别提示这三个介词都可以表示地点，其具体用法如下：(1) in表示地点时，意思是“在，里面，在，中” ；还可以跟大范围的地方，如国家、城市等。派袜子在抽屉里。The socks are in the drawer.X吉姆和他的父母在北京。Jim and his parents are in Beijing now.(2)

6、 on表示“在，的上面，在，之上” ，物体的表面是接触的。X你的棒球在沙发上。Your baseball is on the sofa.X墙上有一幅画。There ' s a picture on the wall.注意：有时候in也可以表示“在，上”，但on是指在物体表面，而in则是指深入的物体的内部。派墙上有一个小洞。There ' s a hole in the wall.(3) under意思是“在，下面"。X汤姆的自行车在树底下。Tomri s bike is under the tree.维拓展|表示地点的介词还有很多，如：behind在，的后面，in f

7、ront of在，的前面，nextto紧挨着，between在两者之间等等。我的家就在学校后面。My home in behind the school.我坐在林芳和卢晴之间。I sit between Lin Fand and Lu Qing. 3. They are on the sofa.sofa 是个音译词，“沙发”就是从这个单词的读音中音译而来。在汉语中有很外来词都是音译过来的，随着中外文化交流和科学技术的发展，许多外来词融入了汉语的词汇中，丰富了我们的语言文字。同学们还知道其他的音译词吗？jeep吉普车,tank 坦克，salad 沙拉,cool 酷 4. I don '

8、t know.know 的意思是“知道，了解，认识“。与no的读音相同。例如：我不认识史密斯先生。I don ' t know Mr Smith.你了解意大利的一些情况吗？抱歉，我不知道。Do you know anything about Italy? Sorry, I don' t know.当回答别人的问题时，如果不知道，就可以用I don ' t know 来回答。使用时，常常在之前加一句Sorry,这样显得礼貌、客气。【牛刀小试】 单项选择()1. -Are these English books?-Yes, are.A. this B. these C. t

19、way. Can you take me home?我迷路了。你能带我回家吗？X You can ' t take these things there.你不能把这些东西拿到那儿去。 2. Can you bring some things to school?(1) some的意思是“一些，若干”。它是形容词，可以修饰名词，它既可以修饰可数名 词，也可以修饰不可数名词。当它修饰的名词是可数名词时，必须用可数名词的复数形式。例如：我有一些关于动物的书。I have some books about animals.请给我拿些水来。Please get me some water.思维拓

20、展(1) some 一般用在肯定句中，在否定句和疑问句中，some要变为any。I have some good friends.(变为否定句)I don ' t have any books about animals.There is some water in the glass.(变为一般疑问句)Is there any water in the glass?(2)在有些时候，some也可用于疑问句。向对方发出邀请，并希望对方作出肯定回答时。冰 Would you like some water? 喝点水吧？向对方委婉、客气地提出要求或建议。Shall we have a re

22、 book to me.把某物拿给某人也可用这种表达：bring sb. sth.例如：你能给我拿些水来吗？Could you bring me some water?特别提示bring , to +地点,如果地点是 home或here ,则省略介词to.不要把你的朋友带到家里来。Don ' t bring your friends home.把新同学带到办Bring the new students here to my office.公室来。方法指津：take与bringtake表示把某物或某人带到某处去，含有远离说话的地方的意思，强调方向性；而bring表示将某物或某人从别处带(

23、拿)来，也强调方向性。 3. I need my hat, my notebook, and a pen.need意思是“需要”。可作实义动词、情态动词和名词。(1) need作为实义动词时，后面跟名词或代词作宾语，也可以跟不定式to do,意思是“需要去做某事”；也可以跟doing形式，表示被动，意思是“需要被，”。 例如：我需要你的帮助。I need your help. 我需要去看医生。I need to see a doctor. 这台电脑需要修理一下了。This computer needs mending.(2) need也可做为情态动词。情态动词没有人称和数的变化，不能独立作谓语

24、，必须与后面的动词原形共同构成谓语。need作为情态动词时，常用于否定句和疑问句中。例如：你不需要做所有的工作。You need n' t do all the work.用need引导的问句做答时，肯定回答用must,否定回答用needn' t。我现在需要打扫房间吗?Need I clean my room now?是的，你必须现在打扫。Yes, you must.不，你不必现在打扫。No, you needn ' t.(3) need用做名词，意思也是“需要”。可用于短语in need of ，“需要，”。例如：他们现在急需清洁工。They are in great

25、 need of cleaners.4. The notebook is on the floor.这句话的意思是“笔记本在地板上”。主语+be+表位置的介词短语，意思是“某物 /某人在某处”。例如：我的钥匙在抽屉里。My keys are in the drawer.思维拓展表达“在某处有某人/某物”还可以用 There be句型。There be句型是个倒装句，在日常生活中使用非常广泛。它的句型结构为"There + be(is, are) + 名词+介词短语”。There is a book on the desk.桌子上有一本书。X There are 40 students

26、 in my class.我们班有 40 个学生。其疑问句形式是将 be提前：Be (Is , Are) + there +名词+介词短语。意为“在某处有某人/某物吗？回答用"Yes, there + be ” 或 "No, there +be +not ”。X Is there a book on the desk?桌子上有一本书吧？Yes, there is. / No, there isn' t. 是的，有一本。/ 不，没有。X Are there any students in the classroom?教室里有学生吗？Yes, there are. /

27、No, there aren' t. 是的，有一些。/ 不，没有。其否定形式是 There +be +not+ 名词+介词短语。There isn ' t a book on the desk.桌子上没有书。There aren ' t any students in the classroom.教室里没有学生。特别提示There be句型遵循一个原则：就近原则。就是说be动词要根据离它最近的那个名词的形式来变化。如果紧挨be动词的名词是单数形式或不可数名词，be就用单数形式is或was；如果紧挨be动词的名词是复数形式，则be就用其复数形式are 或 were。弘 T
