托福听力考试做题步骤解析

       1. 查看笔记，要注意按照笔记所记细节的顺序找答案的位置，因为托福听力的出题顺序一般与录音顺序一致，即与笔记顺序一致。
　　2. 分析选项：将选项与笔记进行比较，通常答案都是笔记内容的同义替换。
　　3. 确定答案
　　Tips 正确选项 VS 错误选项
　　正确：
　　1. 原文中对该专业词汇的正确解释
　　2. 原文重要细节的同义词替换
　　错误：
　　1. 虽然重复听力原文的原词，但偷换概念
　　2. 错误信息或是另外一题的信息
　　3. 文中根本就没有提到的信息
　　4. 不符合常识的答案
　　5. 用主旨题的信息答细节题
　　举个栗子：
　　Male Student： Oh， I see what you mean. Umm， is that that stuff about “hopping genes，” or something like that？
　　Female Student： Right. Although actually they’re called “jumping genes，” not “hopping genes.”
　　Male Student： Oh， OK. Jumping genes.
　　Female Student： Yeah， but they have another name， too， that I can’t think of. Umm... let me see if I can find it here in the book...
　　Male Student： I thank it’s probably on...
　　Female Student： Oh， OK. Here it is. Transposons. That’s what they’re called.
　　Male Student： Let me see. OK. Trans-po-sons， trans-posons. So“transposons” is another name for a jumping gene？
　　Female Student： Right. And these transposons are， you know， like， little bits od DNA that are able to move form one cell to another. That’s why they’re called “jumping genes.” They kind of， you know， “jump” from one cell to another.
　　Male Student： OK
　　According to the conversation， why are transposons sometimes called“jumping genes”？
　　A. They are able to move form one bacteria cell to another.
　　B. They are found in people with exceptional jumping ability.
　　C. They occur in every other generation of bacteria.
　　D. Their movements are rapid and unpredictable.
　　这是一道典型的考概念解释的细节题。问的是为什么 “transposons” 有时候也被叫做 “jumping genes”。
　　首先，对话里多次出现表示概念定义的信号词 “is called”， “name”，因此容易出概念解释方面的细节题。信号句后出现的重点概念 “jumping genes” 和“transposons” 及概念的解释 “And these transposons ... are able to move form one cell to another. ”
　　其次出现了原因信号词 “That’s why”，信号词后是重点：“ ‘jump’ from one cell to another”。同义词替换后得出正确选项为：“They are able to move form one bacteria cell to another”。
