They+are listening. 2)主语+及物动词+宾语： She+likes+basketball. They+know+me. 3)主语+系动词+表语： The bike+is+new. She+felt+worried.交际英语： what can I do for you ? I need to do some shopping.Im worried about my party.指点迷津单元重点词汇点拨 1.pingpong乒乓球 She plays pingpong very well.她乒乓球打得很好。 【点拨】乒乓球也可说table tennis。 2.hard-working努力工作的 He is a hard-working teacher.他是一位勤奋的老师。 【点拨】其他类似的词如：peace-loving爱好和平的。 3.happily幸福地，快乐地 The children are playing happily.孩子们正愉快地玩着。 【点拨】该词为happy的副词形式，作状语。happiness是其名词形式。live ahappy life过去幸福的生活。 4.easily容易地，轻易地 We did it easily.我们很容易地把它做了。 【点拨】其形容词为easy。It is easy for sb.to do某人干很容易。如： It is easy for her to bring the books here. 5.carefully仔细地，小心地 Listen to the teacher carefully!仔细听老师讲! 【点拨】该词为careful的副词。carless 粗心大意的，carefully=with care认真地。如： Youd better do your homework carefully.你最好仔细地做家庭作业。 6.worried担心的，烦恼的 Whats the matter with you,Tom?你怎么啦，汤姆? My parents havent been back yet.I am worried about it.我的父母还没回来，我有点担心。 【点拨】注意worry可作动词和名词，表“担心，焦虑”。be worrid about=worry about“对感到担心”。单元词组思维运用 1.telephone number电话号码 What is your telephone number.你的电话号码是多少? Perhaps his telephone number is wrong.也许他的电话号码是错的。 2.do some shopping买些东西 Were going to do some shopping.我们打算购买一些物品。 【提示】类似词组还有：do sport从事运动，do the cooking烹调，烹饪，do washing洗衣服，do cleaning做扫除，do ones homework做家庭作业，do ones lesson做功课。 Mr.Smith likes doing sport after meals.史密斯先生喜欢饭后参加体育运动。 Is Rose going to do washing this afternoon?今天下午Rose洗衣服吗? I dont like to do shopping with her this afternoon,Mun. 3.Please help yourself请随便吃，请自己动手(拿、吃、抽烟等) Please help yourself to wine.请随便用酒。 【提示】表“吃什么，拿什么”时，该词组要加介词to 再加宾语。如： Boys,help yourselves to more bananas and oranges.孩子们，多吃点香蕉和桔子。 Sir,help yourself to some cigarettes(香烟). 注意：help sb.with帮助某人干。如： She always helps me with my Chinese on Sunday.她星期天经常给我补中文。 4.get ready for为做好准备，为准备好 Have you got ready for the party?这个聚会你已经准备好了吗? 【点拨】get ready to do准备好干。如： Please get ready to run,class. 5.on the other side of在的另一边 On the other side of the river there are some banana trees.在河的对岸，有许多香蕉树。 On the other side of the street there is a book shop.街对面有家书店。 【提示】指两者之中的另一边。 6.like to do与like doing区别 【提示】这两者都表示“喜欢做什么”，区别如下： 1)like to do喜欢做特定的或某次具体的行动，指一时的爱好。如： I like to swim in the river.我喜欢在这条河游泳。(特定场合的具体行动) 试比较：I like swimming.我喜欢游泳。 2)like doing指喜欢做某事，即长期的爱好和兴趣。试比较： Do you like swimming?你喜欢游泳吗?(指长期的爱好) Would you like to swim with me tomorrow?你愿意明天和我一起去游泳吗?(特指明天一次具体行动) 另外：如果用于否定结构，like to do 与like doing就没有什么区别，可以换用。如： I dont like smoking=I dont like to smoke.我不喜抽烟。 7.like与would like的区别： 1)like喜欢，爱好。后接名词、代词、不定式或动名词。 Do you like fish?你喜欢吃鱼吗? 2)would like意为“想要，愿意”，是wish和want的意思。用于礼貌性地提出要求或表示愿意提供帮助。其后可接名词、代词、动词不定式，但不能接动名词。如： Would you like something to eat?你想吃点什么东西吗? 另外，would like sb.to do表“愿意让某人干”。如： My father would like me to go to Beijing with him this summer.今年夏天，我父亲要我和他去北京。二、 学海导航学法指要单元句型思维明晰 1.as+副词+as的句型 Read this passage as quickly as you can.你尽快读完这段短文。 注意：这类句型中第一个as为副词，第二个as为从属连词，引导程度状语从句。如： He ran as fast as he could.他尽力地快跑。 He works as hard as you.他与你一样努力工作。 2.Not否定主语的句型 Not everyone likes sandwiches.不见得每个人都喜欢三明治。 注意：not无论放在句首或句子其它地方，与all,every等词连用时，只表示部分否定，又叫“部分否定句”。如： Everyone does not like sandwiches.不见得每个人都喜欢三明治。 Not all people agree with you.不是大家都同意你的意见。单元难点疑点释疑 1.What can I do for you?你要点什么? 这是对顾客的礼貌用语，还可以说Can I help you?如： What can I do for you?你要点什么? I want to buy a new coat.我想买件新上衣。 Can I halp you? Two cups of coffee.=Two coffees.请来两杯咖啡。 2.She felt worried.她很焦急。 注意：feel是连系动词，worried是形容词，在句中作表语。turn,get,look,be等动词也是连系动词，都可接形容词构成系表结构。如： He felt happy.他很高兴。 The trees turn green.树儿绿了。 1)表示具有某种性质、特征或处于某种状态，常用的有：be,appear,feel,sound,seem,book,smell,taste.等。如： It is not late.时间还不晚。 The dish smells good.这道菜闻着很香。 He seemed to be writing something.他好像在写什么东西。 His words sounds all right.他的话听起来有道理。 2)表示动词所叙述的动作和过程所产生的结果，或者表示状态的变化，常用的有：get,go,come,become,turn,grow,fall,prove,run,make等。如： The custom has now become a rule.那习价已变为成规。 The milk in the cup will go bad.杯子里的牛奶要坏了。 Her face turned red. 3)表示某种持续的状态，常用的有：keep,continue,stnad等。如： She knew she must keep calm.她知道她必须保持镇静。 4)除make等个别词外，几乎所有连系动词都能接形容词作表语。如： Our country is getting stronger and stronger.我们国家日益强大。 5)become,get,look,make,seem,turn等。如： Now you look a grown-up young man.现在你看上去已经是一个成年的小伙子了。 One tree does not make a wood.独木不成林。 He used to be a soldier till he turned writer.他当作家之前曾是名战士。 6)我们还应注意某些连系词和形容词的固定搭配及其褒贬色彩。比如，come多接褒义形容词，而go则多接贬义形容词。如：come true/right变为现实/正确， go bad/hungry/mad/blind/deaf/tird变坏/饿/疯/瞎/聋/累,grow rich/tll/large/clever/old变得富裕/高/大/聪明/年老，fall ill/asleep/silent/生病/睡着/沉默。 3.Im worried about my party.我正担心晚会呢? be worried about 意为“为而担心”。注意该词组表示担忧的状态。如： Mother is worried about his health.母亲担心他的健康。 Are you worried about the meeting?你担心开会的事吗? 4.Ill get another one now.我现在再拿一根来。 注意：one(s),other(s),the other(s)及another的区别： 1)one有下列几种意思： (1)可指人或表示一种。 (2)常用来代替前面刚提到的可数名词，以避免重复，如可数名词为复数，就要用ones来代替。 (3)表示“一个，另一个”用“onethe other”。 2)the others表示其余的几个，要用定冠词the。 others表示泛指“别人”或“别的东西”，常不加定冠词。 3)another意为“另一个，又一个”，强调三个或三个以上人(或事物)中的“另一个”。试比较： Which sweater would you like,the red one or the blue one?你想要哪件毛衣，红色的还是蓝色的? The red one.红色的。 I have two sisters.One is a teacher,the other is a doctor.我有两个姐姐，一个是教师，另一个是当医生。 The children are cleaning the classroom.Some are sweeping the floor,others are cleaning the window.孩子们正打扫教室，一些正在扫地，另一些擦窗子。 Lei Feng was always ready to help others.雷锋总是乐于助人。 Here are three pencils.One is red,another is blue,the third is yellow.这里有三支钢笔，一支是红色的，另一支是蓝色的，还有一支是黄色的。妙文赏析Not Such a simple Question Alan Chang was a handsome(英俊的)young man with good manners(礼貌).One morning he was walking along a street on his way to an appointment(约会).He did not want to be early or late.He had forgotten to put on his watch so he went up to a man who was waithing for a taxi. “Excuse me,sir,”he said,very politely,“but could you tell me the time?” The man,who was very well-dressed(穿着考究的，衣着入时的)and looked quite rich,said nothing.He did not even look at Alan.Alan spoke to him again.“Excuse me,sir.”he said,“but could you please tell me what time it is?” This time the man looked at him,but he did not speak and looked quickly away.Alan thought to himself:Well,hes not deaf(聋的).He must be just rude(粗野的，无礼的). “Why wont you tell me the time,sir?”he demanded(请求，要求).

A.wont she B.will Miss Liu C.is she D.will she【参考答案】 1.C。do,make,cook都含有“做”的含义，但用在食物上只用make和cook,make,侧重于面食的制作，如“包饺子，做蛋糕”等，而cook侧重“烹饪”。句中can为情态动词，后加动词cook原形。 2.D。上、下小汽车时不用get on /off短语，而要用get into/out of。另外前后面分句由and连接为并列句，前后动作应一致，不可能上了小汽车又进了商店，所以应选择下车，即getting out of。 3.A。water为不可数名词，谓语动词要用单数形式，因此可排除C、D项。另外no=not any,any用来修饰water不可缺，因此不能只用is not，而要选A。 4.B。在主从复合句中，除主句为一般现在时的情况外，主、从句在时态上一律要保持一致。本题主句为一般过去时，因此从句也要用过去的时态，D项中feeled为一种错误的过去形式，因此选B。 5.D。never为否定副词，意为“从来没有”，因此陈述部分为否定句。那么反意疑问句的疑问部分要用肯定形式will,主语Miss Liu相对应的人称代词为she，因此选D。类似这种情况的词还有:hardly(几乎不)，few,little(几乎没有),nobody,no one(没有人)，nothing(没有什么)等。.词形变化： 1.day (反义词) 2.long (比较级) 3.snow (现在分词) 4.cloud (形容词) 5.happy (副词) 6.country (复数) 7.stop (过去式) 8.beautiful (最高级) 9.stop (第三人称单数) 10.we (名词性物主代词)【参考答案】1.night 2.longer 3.snowing 4.cloudy 5.happily 6.countries 7.stopped 8.most beautiful 9.stops 10.ours创新园地根据句意选择最佳答案： 1.Hi,Jim. . It was a pleasure. 2. . Thatll be fine.Ill tell Mum.I think Im free that night. 3. . Sure. 4. . Bye! A.Goodbye!
