(对划线部分提问) you collect toys?答案：why; do三、同义句转换一般来说，这类题目有以下四种情况：1、简单句之间的转换 简单句之间的转换通常有：用同义词(词组)、反义词(词组)替换相关的词语，或用意思相同的句型替换。how did you get to the disney island?how did you the disney island?答案：arrive in/ at2、复合句之间的转换复合句之间的转换通常用不同的词改写或改变句子结构。yao ming received thousands of letters from his fans after his leg was broken. yao ming thousands of his fans after his leg was hurt.答案：heard; from3、复合句转换成简单句复合句转换成简单句多用动词不定式，介词短语替换从句或用相同的句型替换。it is three years since i became a middle school student. (改为简单句)i a middle school student three years .答案：became; ago4、并列句或两个简单句变复合句这类题目一般运用并列连词、不定式、或一些关联词。be quick, or you will be late for school again. (改写句子。句意不变) be quick, you will be late for school again.答案：if; dont【技巧点拨】1、注意时态。2、句子的成分不变。原句的句子在改变句型时仍不可缺少，否则句子不完整，但有一个例外，在陈述句改为感叹句时，要增加句子成分，感叹词what和how分别为按句子的要求而增加的定语或状语，句子其他成分不变。3、反复推敲，确保无误。改变后要看看意思是否与要求相符，有没有语法和习惯用法方面的错误。【实战演练】句型转换1. i have already finished my homework.(改成否定句)i finished my homework .答案：havent yet2.mr. chen has worked here since he left school.(对划线部分提问) has mr. chen worked here?答案：how long3.can you tell me how i can find the way to the science museum?can you tell me the way to the science museum?答案：how to find4.tina has seen the film a few times.(改为同义句)tina has seen the film times.答案：a couple of写作指导：叙述过去的经历【写作指导】叙述过去的经历我们往往采用记叙文的方式来写，采用一般过去时交待清楚过去事情发生的时间、地点、人物、事情发生的顺序就可以了。本单元的两篇文章（第一篇介绍博物馆里发生的事；第二篇参观新加坡的所见所闻）就是最好的范例。【例文共赏】假设你上周你和父母去了杭州游玩，请你写一篇短文介绍游玩的情况。when上周where杭州who我和父母how乘了2个小时的火车what参观：西湖，杭州乐园(hangzhou amusement park)，灵隐寺(lingyin temple)等；其中最喜欢（自拟）品尝：美味的杭州地方菜购物：在延安路要求：1、包括信息中提及的所有内容，语句通顺，条理清楚。2、字数90个词左右（开头和结尾已经给出，不计入总词数）, 可适当加以发挥。last week, i went to hangzhou with my parents. it took us about two hours by train. it was a really wonderful trip!one possible version:last week, i went to hangzhou with my parents. it took us about two hours by train.hangzhou is famous for the west lake. soon after we arrived, we took a boat trip on the west lake. in the evening, we took a walk around the lake. the night views were really wonderful. my favourite place was the music fountain. it looked beautiful and fantastic! the next day, we visited hangzhou amusement park. on the third day, we went to lingyin temple. i took a lot of photos there. on the last day, we went to yanan street and did some shopping. i bought some silk scarves for my good friends. during our stay, we also tasted some delicious, well-known hangzhou local dishes.it was a really wonderful trip!【解剖分析】这也是一篇叙写过去的旅游经历的作文，属于记叙文的范畴。我们在读这篇例文时可以发现：1、作者交代清楚了写记叙文的总体要求，即几个基本要素要交代清楚：时间（when）、地点（where）、人物（who/ whom）、事件（thing）； 2、作者按照时间的先后顺序来逐个描述杭州的美景，井然有序。当然我们也可以按照地点，或先总后分，或先分后总等这样的顺序，否则会给人一种杂乱无章的感觉；3、作者做到了恰当选材，做到了有详有略，重点突出。没有一味地堆砌辞藻，只是简单叙述，给人一种朴实无华、耳目一新之感。【拓展演练】假设你是mike，后天是父亲节，请你根据下面所给的信息，写一封信回忆去年夏天与父亲一起爬山的难忘经历，作为一份送给父亲的特殊礼物。注意：1、信中应包含所有提供的信息并展开合理的想象；2、信中不能出现真实的姓名；3、词数：80词左右（信的开头和结尾已经给出，不计入总词数）。dear daddy,its a gift for fathers day when you are reading it.i still remember the day last summer when now, i want to say: i love you, daddy. you raise me up!happy fathers day!yours,mike【范文展示】dear daddy,its a gift for fathers day when you are reading it.i still remember the day last summer when we went mountain climbing together. we started early in the morning. but unluckily, it began to rain on the half way. i got all wet through, feeling cold and tired. so i couldnt stop complaining and wanted to give up. however, you encouraged me to keep trying and put your coat on me softly. you said: “we wont s
