Ben explains the research aims： monitoring whale populations threatened by various factors， tracking their movements to understand their life cycles， and studying their intelligence. Luke then reports on fieldwork： following whales by boat， photographing fins for identification， noting locations to track migration path， creating a database， naming the group， and sharing information with other research teams. 听力素养“漫养成” |掌握规律技法| 抓住话语中的意流指示词 意流指示词是指在句子开头或句子与句子之间具有逻辑关系的某些连词、副词或词组。如yes， sure， certainly， of course， no， sorry， well， not really， why not， but， however， yet， besides等，它们连接的句子或句子成分往往是说话人要强调的内容。 一、语气性意流指示词 其中yes， no， sure， certainly， sorry等是表明说话人态度与反应的语气性意流指示词。根据此类词，我们可以了解说话人的基本态度。一般来说，如果在句子开头听到yes， sure， certainly， of course，表明说话人对某事肯定或赞许；如果是no， not really， sorry， I am afraid，则表明说话人对某事否定或不同意。 [典例] 　Q：What does the woman's answer mean? A．She doesn't want him to sit beside her. B．She doesn't like him at all. C．Please sit down. [听力原文] M：Excuse me， do you mind my sitting here? W：Oh， no， of course not. [分析]　由于Do you mind doing sth.是“你是否介意”的否定性问句，回答时用“no”，是不介意的意思，表示同意，因此C项为正确答案。如果女士回答时用“yes”，说明她介意，也就是表示反对。 二、转折性意流指示词 but， yet， however， besides等是转折性的意流指示词，其中but出现的频率最高。当话语中出现but一词时，要特别注意but后的内容。因为but前的往往是婉转的客套话(冗余信息)，而后面的才是说话者真正的看法(主要信息)。在口语表达中常见的还有to be honest， to tell the truth， in fact， as a matter of fact， actually等。 [典例] 　Q：What does the man want to do with the coins? A．He needs them for his bus fare. B．He lends them to the woman. C．He buys some things with the coins. [听力原文] W：I wonder if you have some change.I want to make a call. M：I would like to lend you some change， but I have only three coins， and I need them for my bus fare. [分析]　由男士说的话“but I have ...fare.”可知，他需要用这些硬币坐公交车，故选A。 这样的例子有很多，它们的共同之处都是but(或其他转折性意流指示词)后的内容是回答提问的主要信息。听清其意，选择正确的答案就很容易了。 三、倾向性意流指示词 倾向性意流指示词一般不出现在句首，而是句子中间的动词或助动词词组，如would rather ...， prefer ...to ...， had better， prefer ...rather than ...，表示说话人通过比较与选择，喜欢或情愿采取的某种行为。它们多用于购物、就餐、旅游等存在比较与选择机会的场合。例如，当顾客去商店购物时，售货员常会问： Which do you prefer， A or B? 对话情景提供了A、B两种可供选择的物品，如果选择了A，那么回答时有以下几种说法： I prefer A to B. I prefer to take A rather than take B. I would like A rather than B. 紧跟在prefer， would rather或would like后面的内容是说话人倾向的目标，因此往往是信息的重点。 [典例] 　Q：What does the man imply about Marion? A．She doesn't like going shopping. B．She went shopping yesterday. C．She doesn't live near the shops. [听力原文] W：Didn't Marion go shopping with you yesterday? M：Even if she hadn't had a lot of study， she would have preferred staying home to going shopping. [分析]　在这个例题中，只要我们把握住prefer A (staying home) to B (going shopping)的句型结构，就会知道Marion的倾向是“待在家里”而不是“去购物”。与此对应的选项是A。 |多积主题表达| “海洋保护”场景听力表达 1．marine pollution 海洋污染 2．ocean conservation 海洋保护 3．endangered species 濒危物种 4．plastic waste 塑料垃圾 5．marine ecosystem 海洋生态系统 6．sustainable fishery 可持续渔业 7．We must take immediate action to stop marine pollution. 我们必须立即采取行动来阻止海洋污染。 8．The goal of ocean conservation is to maintain the health of our oceans. 海洋保护的目标是保持我们海洋的健康。 9．Many endangered species in the ocean are at risk of extinction. 海洋中许多濒危物种面临灭绝的危险。 10．Overfishing has caused serious damage to marine resources. 过度捕捞对海洋资源造成了严重损害。 11．Plastic waste is a major threat to the marine environment. 塑料垃圾是海洋环境的主要威胁。 课时跟踪检测 第Ⅰ卷　语言基础训练 (一)单词拼写(6分) (1)The contents of the report were leaked to the ______ (新闻界)． (2)Everyone had ______ (仁慈) on the children living in such a terrible environment.
