教学步骤：1.听力练习2.课文讲解3.中考复习名词Have you packed yetLearning Aims : Use the present perfect tense to talk about recent events .1. bathing suitbathing suit 动名词作定语，修饰名词，如singing lessonrunning star swimming pool另外bathing 做名词，意为“游泳，洗澡”。
The bathing here is safe .He’s fond of bathing .I have bought a bathing suit .Take a bath 他每天早晨洗冷水澡Give sb . a bath 妈妈过去总是每周给孩子洗两次澡。
2. street mapstreet map 名词作定语修饰名词时，一般只将被修饰的名词变为复数。
如girl students shoe shops furniture stores egg noodles .但是变为复数时，将man或woman与修饰的名词都变为复数three men doctors two women shopkeepers3. Have you fed the cat yet ?feed ……to ……feed…on…“用……喂”“把……喂给……”Have you fed the animals ?He fed sheep on/ with grass .He fed grass to sheep .4. I have already put it in my suitcase .现在完成时态中，有一些标志性的时间状语如“already/ never/ ever/ just /before/ yet /so far /in the last/past ten years .”等1)我已经做完了我的大部分工作。
(already)2)他们刚刚到达。
(just)3)我曾经去过北京。
(ever)4) 我以前见过他。
（before）put on put up put offput down put away5 I will do it in a minute .in a minute .意思为“一会儿，马上”“in+时间段”，用于将来时态中，表示“多久之后”My parents will return in half a month .We’ll finish our work in two days .My son’s birthday is in two weeks’ time .6 Have you turned off your radio ?turn on turn off turn up turn down1)他一到家就开电视2)记着把它关了3)请关灯当你离开时。
7 Sorry I couldn’t get back to you sooner .get back to sb= write back to sb I will get back to my mother .get bact= be back = come backHe’ll come back in a minute .When did you get back to school from your holiday ？Soon可置于句末、句中，有时也可放句首。
放在be 之后。
Soon her mother will go to Europe.I have to go home very soon .The sooner , the better .8 I have so many chores to do today .so many chores 意为“许多工作”so如此这样用为修饰形容词作副词。
Such做形容词“如此的，这样的”用来修饰名词。
但与many much few little 连用时只能用so不能用such so many +可数名词。
e.g. I have so much homework to do .Have something to do 有事要做have nothing to do 无事可做have nothing to do with 与……无关I have nothing to do every day .This kind of thing has nothing to do with me .9 I started about an hour ago ,but I haven’t finished .finish sthWhen are you going to finish your homework ?finish doing sthThey will finish talking in ten minutes .10 I haven’t done any of these things yet because my grandfather came to chat with me .yet是副词，“还不”，用与疑问句时意为“已”，用于肯定句时为“到目前为止”。
Has he come yet ? No , not yet .This is the biggest understandground lake yet discovered .Chat about sthThey chat about Tom’s behavior .chat with/ to sbMy friend Liu Fang often comes to chat to me . I also like chatting with her .11 start = begin后跟动名词和不定式（start = begin to do / doing），跟动名词说明动作将持续下去，跟不定式只表动作的开始。
Start用与进行时态或宾语是表示心理激动时，这些词本身就有延续性，不能用动名词，只能用不定式。
She is starting to feel hungry .12 number of 相当于the number of ,意为“……的数字，数目”，一般后面接名词复数，number是句中真正的主语，由介词of引出的短语是修饰number的定语，其谓语动词用单数。
如： The number of the students in this class is fifty .The number of books in our school library is more than 10 000 .与the number of 相近的词是a number of . a number of 意为“许多，大量”，相当于many a lot of 后接可数名词复数，做主语时，谓中动词用复数。
1.—How many students are there in your school ?— the students in our school over two thousand .A. The number of , isB. The number of , areC. A number of , is2. A large number of students in this school from the country. They work very hard .13 Won an awardwin 后面不接表示“人或队”的词，只能接表示“斗争，战争，比赛”等意思的词；如果宾语是表示人的名词，应用动词beat（击败）一、词汇1． suit [sjut, sju:t] n.请求，求婚，起诉，一套衣服。
它可作及物或不及物动词用，意思是“适合，中……的意，（使）配合，（使）适应，相称，彼此协调”等。
2．water [′w t ] vt.& vi.浇水，浇灌；流泪，流口水。
可作名词用，表示“水，水位，口水，尿”。
复数表示“矿泉水，海域，水域”等。
3． wood [wud] n.作“木材、木头”解时是不可数名词；作“森林、树林”解时是可数名词，且常用复数4． light [lait]含义很多，既可作动词用，还可作名词或形容词和副词用5． last [l st; la:st] adj.最后的，最近的，最后过去的，紧接前面的，仅余的，极少可能的，最终的，最新式的。
可作副词和名词。
还可作动词用，表示“持续，维持”。
6．appear [ ′pi ] vi.出现，看来，好像。
它的反义词是disappear；名词是appearance，可以表示“外表，外貌”。
7． miss [mis] vi.错过，遗漏，想念，未达到。
可作名词用，表示“小姐；失误；避免”。
8． search [s :t ] vt.& vi.搜查搜索，细看，详细调查，穿过，探究。
可作名词用。
9． clear [kli ] vt.& vi.清除，扫除；穿过，越过；为……结关，净得；消失。
它可以作形容词和副词用。
二、语法1、现在完成时主要强调过去发生的动作对现在造成的影响，或过去发生的动作还未结束，一直持续到现在或将来，重点在于对现在的影响。
①表示过去发生或已经完成的某一动作对现在造成的影响或结果。
常用的时间状语：already，get，never，just，before，recently，for+一段时间，since+一段时间I have lost my key.（说明过去某时丢的，现在还未找到。
）②表示过去已经开始，持续到现在的动作或状态。
I have known him for ten years.The dog has been dead for three days.③表示从过去到现在之间曾经经历过的事。
We have been to the Summer Palace twice.【请注意】因为含有for加一段时间或since加一个时间点这样的时间状语的完成时，有动态和延续性的特点，所以不能使用终端动词或瞬间动词。
例：My sister has been here for 5 days.（过去分词做表语表示状态，可以延续）My sister came here 5 days ago.（终端动词）2、现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago 等）连用。
