Try to notice which words are stressed and find out the rule of the stress of sentences. 句子重音句子重音 在连贯的话语中,不可能所有的词都同样重要,必须有些词较为关键,有些词则相对次要 一些。一般来说,关键词需要重读,这就是句子的重音,而其他词则不必重读。或者可以 说成:实词重读,虚词不重读。 一般需要重读的词(实词/关键词): 动词、名词、形容词、副词、数词、疑问词和感叹词等。 一般

25、不需要重读的词(虚词/非关键词): 助动词、情态动词、冠词、介词、连词、人称代词等。 (1)实词不重读的特殊情况。 实词第二次出现:He thinks of that as a child thinks. 一个名词被第二个名词修饰:I met her at the railway station. 代替词:Which book do you want? The small one. 感叹句中的 what 和how:What a good day it is! How beautiful she is! street 在专有名词中:Wangfujing Street this在这些短语中:thi

26、s morning/afternoon/evening (2)虚词重读的特殊情况。 情态动词、助动词和系动词be在句首、句尾和表示否定时: Do you like it? Yes, I do. Are you a doctor? Yes, I am. Can you help me? Yes, I can. I dont like you. He isnt a worker. 情态动词表示可能、惊奇和肯定时:They may come this evening. Can it be five already? He must be in the room. 介词在句首和句尾:In the bo

29、 What time do you usually get up? B: At eight thirty in the morning. A: How do you get to school? B: I ride my bike. Its good exercise. 如何在听的过程中抓住定义或释义获得信息? 在听的过程中遇到不知道的词汇或内容时,关注随后的句子看看是否有定 义或释义、同义词等,这些能帮助理解信息。 (1)定义或释义。 定义或释义往往是对前文的词汇进行进一步的解释、对比或举例说明,常 用的开头有: “Its like ” “That is” “That is to say”

30、“In other words” “For example/instance”。 (2)同义转述。 同义转述是指用不同的方式表达同一种含义。在听力中,同义转述的使用 可以增加题目的灵活性,当某些关键词难以理解时,我们可以根据同义转述 做出判断。 W: Did you hear that Mike had been dismissed by his boss? M: Dismissed?He was fired again! I cant believe it. 上面“He was fired again.”就是对“dismissed”的同义转述。 在听力考试中,句子重音可以帮助考生找到关键词,正确理解所听的内容。 一般情况下,在不需要特别强调或对比某些内容时,句子的重音通常落在最后 一个出现的实词上。例如:The course was more difficult than she had expected, but she got a lot out of it.这个课程比她想象的难多了,但她从中学会了很多东 西。 在这个句子中,只要听到重读的词或词组course、 more difficult、 expected、 got、 lot、 out,就不难正确理解句意。
