5. 改写简单句和合并句子 改简单句是把一个复杂的长句改写成简单句子，通常会使用连词来连接； 合并句子是把两个简单句合并成一个长句，也会借助到连词，副词等等来连接； 常见的转换方法有：用不定式替换，用介词短语替换，用名词短语替换，用分次短语替换，用“疑问句”+不定式”替换； 【例1】I have no idea how I can operate the new machine. (改为简单句) I have no idea ________ ________ operate the new machine. how to 6.被动句，感叹句，反义疑问句 被动句: 助动词be+及物动词的过去分词”构成 (即be + done ) 感叹句: (1) How+形容词/副词+主语+谓语！ (2) What +不可数名词/可数名词的复数+（主语+谓语）！ (3) What a/an + 可数名词单词+(主语+谓语)！ 反意疑问句: 前肯后否,前否后肯. 警惕陈述句中常出现的六大隐形否定词：never, little, few, hardly, seldom, rarely（俗称六大隐形否定词！） 【例1】: The scientists will do much research work in many fields of science soon.（改为被动语态） Much research work will ______ _______ in many fields of science soon. 【例2】Mr Li made him copy the text ten times. (改为被动语态) He was made _____ _______the text ten times. 【例3】The beach is a nice place for tourists.(改为感叹句) _______ ______ nice place the beach is for tourists! 【例4】Those volunteer gave me very important information. (改为感叹句) _______ ________ information those volunteer gave me. 【例5】Your mother has never tried shopping on the Internet, ________ _________ ?(改为反意疑问句) be done to copy What a What important has she 2. 关键词法 指在题目中找出可以对判断答案起到至关重要作用的词，只要找到这个key word，也就找到了解题的突破口的方法。 【例1】Look! Jim’s mother _________with some aged people in the park. A. dances B. danced C. is dancing D. was dancing 【解析】 审查题干，我们很容易发现一个关键时间状语，look! 就说明是当下正在发生的事情，用现在进行时。故此题选C。 3. 类推法 　　如果对选项中给出的答案没有十分的把握，或对正确答案摇摆不定，不妨利用“如果A对，那么B也对”的类推法，把A和B都排除以缩小正确答案的选择范围。 【例1】Tom would decide _________. 　A. What he would do next 　B. when would he leave 　C. how would he spend the holiday 　D. where would he live. 【解析】这题是考查宾语从句知识。如果考生无法确定答案，那么通过观察可以发现，B、C、D选项的共性是疑问句格式没有发生变化。若B正确，那么C、D也是正确的，故B、C、D都排除。只有A才是正确的。此题选A。 4. 瞻前顾后法 多用于两个或两个以上句子或对话形式命题的题目 【例1】---We are going to see Harry Potter and the Deathly Hallows(哈利·波特与死亡圣器) this afternoon. Would you like to join us, Tom? ---__________. I’m going to v
