A．Take fitness classes. B．Buy a pair of gym shoes. C．Change his work schedule. [Text] M：Hello，my name is Jack.I need to get in shape.How do I register for the classes? W：We'll need you to join the gym，and then you can find out which classes fit your schedule the best. [分析]　听力之前关注题干中的关键词what，Jack，do，问题是Jack要做什么。带着这些关键词，注意获取动作信息。听力材料中有问句“How do I register for the classes？”由此可知应该是报名“参加课程”。题中的A项take fitness classes与register for the classes 同义，故选A。 　What's the weather like now? A．Snowy.　　 　B．Windy.　　 　C．Sunny. [Text] W：It stops snowing，but there's a bit of wind. M：And the streets are covered with ice.The weather forecast says it won't be sunny until tomorrow. [分析]　听力之前关注题干中的关键词what，weather，now，了解问题是“现在天气如何”。带着这些关键词，注意获取天气状况信息。听力材料中有“stop snowing”“a bit of wind”和“won't be sunny until tomorrow”经过筛选，现在的天气应是“windy”，故选B。 　What is the woman worried about? A．The salary. B．The responsibility. C．The working hours. [Text] M：Linda，I've been talking to the other managers and we'd like to offer you a promotion to assistant manager.This job comes with more hours，more responsibility，and of course，a pay raise. W：Wow! How many hours would it require? I'm nervous that working too much will affect my studies. [分析]　题干的关键词为worried和what，询问“女士担心的事情”，带着关键词，获取听力材料中的信息。既有hours，responsibility也有pay，妇女的话语“working too much”和“affect my studies”，听力中的be nervous与be worried同义，working too much指的是干活太多，C项中的the working hours( 工作时间)符合语境。故选C。 [重点词汇] 1．convenience n.方便，便利；便利的事物 (1)at one's convenience　在某人方便的时候 for one's convenience (of)＝for the convenience of sb　为了某人的方便 for convenience　为了方便起见 convenience food/store　方便食品/便利店 (2)convenient adj.　方便的 It is convenient for sb to do sth　某人方便做某事 [经典佳句] Do let me know if it's convenient for you.I would appreciate it if you could give me an early reply.(邀请信) 如果您方便的话，请告诉我。如果您能早日给我答复，我将不胜感激。 We have provided seats for the convenience of our customers. 为了方便顾客我们备有座位。 convenient作表语时，不可用人作主语，而要用物作主语或用it作形式主语。如“当你方便的时候”应翻译成“when it is convenient for/to you”，而不是“when you are convenient”。 [即学活用]　单句语法填空/一句多译 ①They have good reasons for driving their kids to school，mostly to do with safety and ___________(convenient).(2024·新课标Ⅰ卷，听力) ②Any help from you will be greatly appreciated.Please give me a reply __ your convenience. ③Will it be convenient ___ you to start work tomorrow? ④方便的话，我们希望你能接受我们的邀请。 a．We hope you will accept our invitation ___________________． (convenience) b．We hope you will accept our invitation _______________________ _____．(convenient) 2．effect n.效应；影响；结果 (1)come into effect 　生效，开始实施 bring...into effect　实施 take effect　生效，开始起　作用 in effect　实际上，事实上 have a/an...effect on/upon...　对……有……影响 side effect　副作用 cause and effect　因果 (2)effective adj.　有效的，起作用的 (3)effectively adv.　有效地 [经典佳句] The new traffic rule came into effect.In effect，it has an effect on people's life in many ways. 新交通法规开始实施。实际上，它在许多方面影响到我们的生活。 [即学活用]　单句语法填空/完成句子 ①Should house property tax (房产税) come ____ effect，China might witness a fall in house prices. ②Optimism has a positive effect _______ people's physical and mental health，of which I'm very convinced. ③With such campaigns __ effect，China's waterways are heading towards a clean and sustainable future.
