A．In a classroom. B．In a hospital. C．In a museum. 【听力原文】 W：Excuse me，sir.Visiting hours are over now.Your wife must get some rest. M：Oh，I'm sorry，doctor.I didn't hear the bell，or I would have left earlier. 【分析】　首先根据题干中的关键词“where，take place”可知这是一道考查事件发生在哪里的试题，听时要仔细听关于称呼或地点的词语。再根据三个选项中介词冠词一致，确定听的重点是关于称呼或地点的词语，然后边听边做好记录。女子说探视时间结束，男子的妻子需要休息。男子称呼女子为医生，并表示抱歉，自己应该早点离开，可推测对话发生地点为医院。关键信息点为男子称呼女子“医生”。 二、记逻辑词和短语提示 逻辑词和逻辑短语是连接一篇文章的筋骨和脉络。因此，听清楚逻辑词，记录下来，对于内容之间的关系和顺序等的了解就容易了。 听力中常出现的逻辑关系： ★Description and example ★Sequence ★★Cause and effect ★★Problem and solution ★★★Comparison and contrast 　听第7段材料，回答第8至10题。 8．What has Kate's mother decided to do? A．Return to school. B．Change her job. C．Retire from work. 9．What did Kate's mother study at college? A．Oil painting. B．Art history. C．Business administration. 10．What is Kate's attitude toward her mother's decision? A．Disapproving. B．Ambiguous. C．Understanding． 【听力原文】 W：Guess what？My mother's decided to go back to school. M：Why? W：Well，she always loved art，but learned business administration at college，because her parents thought it was difficult for an artist to find a job. M：So she wants to study art now? W：Yeah，oil painting.It's been her dream for a long time. M：It's nice to return to learn what she loves.But，Kate，I still think old age should be about peace and relaxation.Hurrying to school every day and having to pass exams sounds a bit too much for her. W：You know，she retired last year and I'm leaving for the university soon.She needs to find something interesting to do. M：Well，maybe，if it's what she wants. 【分析】　在听录音的过程中，速记逻辑词why，but，because，you know等词后的内容，根据 “but learned business administration at college；She needs to find something interesting to do.” 就比较容易选出9、10题的答案 (C、C) 了。 三、利用缩写、简写、逻辑符号、换词减少记录时间 记笔记关键是速度。学生可以自己创造一套符号来表示意思 (缩写、图形等)，只要自己明白就可以了。例如，用“bc”表示because，用“yrs”表示年份，用“＋”表示and，等等。换词，不需要改成复杂深奥的词语，恰恰相反。举个例子：当你听到...opportunity...的时候，如果要写下来，那多麻烦啊，要考虑复杂的拼写。但是如果你改写成chance，那就节约了很多时间。还有，没人说只能写英文啊！当你听到large，small的时候，你不觉得记上“大”“小”更快吗？所以当你发现某个词出现得比较常见但是又浪费时间去记录它的话，就可以利用换词解决。 　听第9段材料，回答第14至17题。 14．Why does the man seldom do exercise? A．He lacks motivation. B．He has a heart problem. C．He works all the time. 15．What does Jacob Sattelmair probably do? A．He's an athlete. B．He's a researcher. C．He's a journalist. 16．Why does the woman speak of a study? A．To encourage the man. B．To recommend an exercise. C．To support her findings. 17．How much time will the man probably spend exercising weekly? A．300 minutes. B．150 minutes. C．75 minutes. 【听力原文】 M：We all know that exercise is good for us，but sometimes it seems too hard to leave the sofa. W：I can see that.You seldom do exercise. M：Plus，having the doctor tell us to get two and a half hours of exercise a week doesn't really help our motivation much. W：Don't be discouraged.Now，a new study suggests getting benefits from exercise doesn't have to be that demanding.Jacob Sattelmair from Harvard University has done a study into how much exercise is needed to lower the risk of heart attacks. M：Hmm，interesting. W：The study showed that people who put in three hundred minutes a week of exercise had a 20% lower risk of death due to heart disease.Still，the people who exercised 150 minutes a week did pretty well too，lowering their death risk by 14%. M：And what about the people who exercise half as much as that？Like what I probably do.Does that help? W：Of course.Even 15 minutes would help. 【分析】　14题根据记录“not...help...motivation...”可以选出答案；15题可以根据记录“do a study into...”选出答案；16题女子鼓励男子不要丧失信心 (Don't be discouraged.)，然后举例来自哈佛大学的Jacob Sattelmair的研究成果。可知女子说该项研究的目的是鼓励男子。注意“Don't be discouraged”与“To encourage the man”之间的同义转换；17题可以根据记录“...150ms...1/2...”得出正确答案。 总之，听力测试具有瞬时效应、信息效应和心理效应的特点，需要稳定心理才能沉着应答，发挥出正常的水平。在平常的听力训练当中，应排除杂念，集中精力，全身放松，充满信心，沉着冷静，保持最佳竞技状态。在考试时，遇到未听懂或未完全听懂的内容，对于实在没把握的内容，也应采用阅读理解的方法去推测。 [重点词汇] 1．in harmony with 与……和谐，与……协调 [经典佳句]　Your suggestions are not in harmony with the aims of this project. 你的建议与本项目的目标不符。 (1)harmony n.　和谐；融洽 in harmony　和谐 out of harmony　不协调，不和谐 live/work in harmony (with) (与……) 和睦地生活/工作 social harmony　社会融洽 colour harmony　色彩协调 (2)harmonious adj.　和谐的；融洽的 a harmonious society　一个和谐的社会 [即学活用] 单句语法填空/完成句子 ①First and foremost, a　harmonious　(harmony) but competitive interaction in a group will help with everyone's learning. ②In addition，every student can be in harmony　with　foreign friends，which makes it easy for you to get along with them. ③　Only if people live in harmony with each other　can we have a harmonious society. 只有当人们和睦相处时，我们才能有一个和谐的社会。 2．balance n.平衡 [经典佳句]　Life is like riding a bike.To keep your balance, you must keep moving. 人生就像骑单车，只有不断前进才能保持平衡。 (1)keep one's balance　保持平衡 lose one's balance　失去平衡 out of balance　不平衡 keep the balance of nature　保持生态平衡 (2)balance sth against sth　权衡；斟酌；比较 (3)balanced adj.　保持平衡的 keep a balanced diet　保持饮食均衡 [即学活用] 单句语法填空/完成句子 ①You have to balance the advantages of living in a big city　against　the disadvantages. ②People have learnt the importance of keeping a　balanced　(balance) diet to satisfy their nutritional needs. ③Suddenly a girl　lost her balance　and fell down in front of him.突然有个女孩在他前面失去了平衡而跌倒了。 ④The child couldn't　keep his balance　on his new bicycle.孩子骑他的新车时不能保持平衡。 3．do one's part for sth尽自己所能做某事 [经典佳句]　I am willing to do my part for contributing to environmental protection. 我愿意尽我所能为环境保护做出贡献。 take part in　参加 play a part in　在……起作用；在……扮演角色 for one's part　就某人而言 [即学活用] 完成句子/一句多译 ①I　took part in an English speech contest　last week. 上周我参加了一个英语演讲比赛。 ②These days work　plays an important part in　a single woman's life. 现在，工作在单身女性的生活中起着重要作用。 ③　For my part　，I found the meeting successful. 就我而言，我认为这次会议很成功。 ④就我而言，我认为这次关于怎样减少我们的碳排放的会议最富有成效。 a.　As far as I am concerned　，I found the meeting on how to reduce our carbon footprints most fruitful.(concern) b.　For my part　，I found the meeting on how to reduce our carbon footprints most fruitful.(part) 4．view n.风景；视野；意见 v.观看；看待 [经典佳句]　The view from the top of the tower was spectacular. 从塔顶远眺，景色蔚为壮观。 (1)in one's view　在某人看来 come into view　看得见；进入视野 in view of　考虑到；由于 (2)view...as　把……看作 [即学活用] 单句语法填空/补全句子 ①When the car goes around the corner, our house will come　into　view. ②　In　my view, no matter what situation we are in, bad or good, we should not waste food. ③We view every customer　as　a partner. ④　In view of the bad weather　(鉴于坏天气)，we will cancel the outing.
