Unit 9 Can you come to my party?词句精讲精练词汇精讲1. prepare forprepare作动词,意为“准备”。其用法归纳如下:（1） prepare sth.意为“准备”,宾语是所准备的内容。例如:Mother was preparing dinner in the kitchen. 妈妈在厨房准备饭菜。He had a speech to prepare that evening.那天晚上他得准备一个报告。（2） prepare to do sth. 表示“准备做某事”。例如:Taking out a piece of paper, he prepared to write to his parents. 他拿出纸,准备给父母写信。He is preparing to go on a trip. 他正准备去旅行。（3） prepare for sth.表示“为做准备”。例如：He is busy preparing with great care for the Congress.他们正忙着精心准备这次代表大会。Hope for the best and prepare for the worst. 抱最好的希望,做最坏的准备。（4） prepare sth. for. 表示“为准备某物”。例如:Please prepare the table for the dinner. 请摆好桌子吃饭。You must prepare a room for the guest. 你必须为客人准备一个房间。 2. hang outhang out是动副结构的短语，意为“闲逛”。例如： I hung out with my friends and took lots of photos. 我和朋友们一起闲逛，还拍了许多照片。【拓展】 hang的其他搭配：hang about=hang around 闲逛，徘徊，逗留；hang up挂断（电话）；hang on不挂断； hang意为“逗留，悬挂”时，过去式和过去分词都是hung；hang还有“吊死，绞死”的意思，但当hang意为“吊死，绞死”时，其过去式和过去分词都是hanged。例如：Thick clouds hung low and covered the sky.厚厚的云低悬着，遮住了整个天空。He was hanged at Landsberg prison on June 8, 1951.他与1951年6月9日在兰茨贝格监狱被绞死。3. inviteinvite作及物动词，意为“邀请，招待”。常用结构为：invite sb. to do，invite sb.+副词或介词短语，表示“邀请某人做某事, 邀某人去某地”。例如：Theyve invited us to stay for the weekend.他们已邀请我们留下来度周末。Who have you invited to your house for your birthday party?你请了谁到家里来参加你的生日晚会？4. acceptaccept作动词，意为“同意, 承认”。例如： It is generally accepted that smoking is harmful to our health. 吸烟有害健康，这是大家公认的。【拓展】 receive与accept的辨析：两个词都作动词用，都表示“接受，收到”之意，但在用法上有所不同。receive表示的行为与主观意愿没有关系，着重于行为本身，不涉及收到者是否同意。动作本身有一定的被动性。accept表示的行为由主语的主观意志所决定，强调经过主语的考虑而接受。动作本身是主动的。例如： I received his invitation to the party yesterday, but I refused to accept it. 昨天我收到了他的晚会请柬，但我拒绝接收。5. refuserefuse作动词，意为“拒绝”。常用搭配有：refuse to do sth.拒绝做某事 (作为不及物动词) ；refuse sb. sth.为某事拒绝某人（作为及物动词） 例如：He refused to change his mind.他拒绝改变主意。The United States has refused him a visa.美国拒绝给他发放签证。She refused their invitation.她拒绝了他们的邀请。6. replyreply既可作不及物动词，又可作及物动词，还可作名词。（1）作不及物动词，意为“回答”，可用“reply to(sb. /sth. )”表示“对做出回答”。例如：He failed to reply to my question. 他没能回答我的问题。What did he do in reply to your challenge? 你提出与他较量，他做何反应?（2）作及物动词时，其意为“回答，回答说”。例如：He replied that this was absolutely impossible.他回复说这是绝对不可能的。She sighed, but didnt reply. 她叹了口气，没有回答。（3）作名词时，意思为“答道，答复”。例如：A few weeks later I received a reply.几个星期后，我收到了她的回信。I called out a challenge, but there was no reply.我提出挑战，但是没人回应。7. withoutwithout是介词，意为“无，没有”，后接名词、代词或动词的-ing形式。without构成的介词短语具有否定含义，在句中相当于构成了否定句。例如： I cant do it without your help. 没有你的帮助，我不能做这件事。 He went to school this morning without having breakfast. 他今天早上没吃早饭就去上学了。【拓展】 without的反义词是with，表示“拥有，带有”。例如：She was a lively young woman with patience and imagination.她是个充满活力的年轻女性，富有忍耐力和想象力。 Mr. Brown bought a garden with a beautiful lake.布朗先生买了一个带有漂亮湖泊的花园。8. surprisedsurprised 是形容词，意为“吃惊的，感到惊讶的”，句子的主语通常是人。例如：Im surprised at the accident. 我对这起事故感到很吃惊。How surprised the students are!学生们是多么吃惊啊！【拓展】（1）surprising也是形容词，意为“吃惊的，令人惊讶的”，常修饰物。例如：He told me something surprising. 他告诉我一些令人吃惊的事情。(2) surprise作动词时，意为“使惊奇，使感到意外、吃惊”。例如： What surprised you? 什么事使你感到意外？（3) surprise作名词时，意为“吃惊，惊讶”。这种吃惊可能包含着“高兴、害怕或忧虑”。例如： He gave me a surprise by arriving early. 他的早到使我大感意外。（4）作名词用时还可构成短语： to ones surprise意为“使某人吃惊的是”。 in surprise意为“吃惊地”。 例如： To my surprise, he passed the exam. 使我吃惊是，他竟然通过了考试。 He looked at me in surprise. 他吃惊地望着我。9. available（1）available作形容词，意为“现成可使用的，可获得的，便利的，有效的”。例如： Ill send you all the books available. 我将把我能得到的书给你寄去。My bicycle is not available, and it is being repaired.我的自行车现在不能用, 因为正在修理。The season ticket is available for three months. 季票有效期为三个月。（2）available还表示“可会见的,可取得联系的”。例如： The doctor is not available now. 医生现在没空。He was not always available to everyone. 并不是人人总能找到他。10. missmiss为动词，意为“想念，思念”。例如： Ill miss you when you go to Canada. 你到了加拿大以后，我一定会想你。 【拓展】(1) miss作动词还有“未击中，未抓住”的意思。例如： I tried to hit the ball but I missed. 我努力地想击中球，但却未成功。(2) miss还可意为“未赶上，错过”，是动词。例如： I missed the football match on TV last night. 我错过了昨天晚上电视中的足球赛。(3) miss与like; mind; finish; enjoy; practice; be busy; stop; cant help; give up等词一样后接动词的-ing形式。例如： I dont want to miss seeing that film on television tonight.我不想错过今晚在电视上看那部影片的机会。词汇精练 I. 英汉词组互译。1. prepare for _ 2. 闲逛_3. take a trip _ 4. 答复某事_5. hear from sb._ 6. 后天 _7. another time_ 8. 盼望，期待 _9. turn down_ 10. 前天 _II. 根据汉语或首字母提示补全单词。1Lets play football tomorrow!SorryIm afraid I cantI have to study for an e_2Whats wrong with you，Mum?I have the _(流感)，and I feel terrible3Are you a_ after school?
