美语听力与发音技巧第二期
摘要: 在美式英语中,音节重音的位置可以改变单词的词性和含义:通常重音在第一个音节时为名词或形容词,重音在第二个音节时为动词。
- 英语中至少有14对单词仅靠音节重音位置区分词性,如 addict、convict、permit 和 perfect。
- 重读音节发音更响亮、更长,非重读音节则弱化且元音常被弱读。
- 例如,'permit' 作名词(许可证)时重音在首音节,作动词(允许)时重音在第二音节。
- 正确使用重音有助于准确表达词义,避免交流误解。
- 掌握重音规律是提升听力理解与发音自然度的关键技巧之一。

Welcome to Daily Tips on Learning English. Today’s tip is on how syllable stress can affect the meaning of words.
Remenber that stressed syllables are said louder and are lengthened, and unstressed syllables are pronounced more softly, and often have the vowel sounds reduced.
Sometimes, this difference can be the difference between a verb and a noun, or an adjective.
There are at least 14 pairs of words in which syllable stress alone makes this difference. Some examples include `addict, a`ddict, `convict, con`vict, `perfect, per`fect. Each time the second syllable is stressed, the word is a verb. When the first syllable is stressed, the word is either a noun or an adjective. Let’s look some examples more closely. `Permit, per`mit, a `permit is a noun, it is a piece of paper which authorizes you to do something. For instance, a fishing `permit allows you to go fishing. Per`mit is a verb. It means to allow. For instence, fishing isn’t per`mitted here without a `permit.
Another example is `perfect, per`fect. `Perfect is an adjective. It means 100% correct, no mistakes or errors. The verb is per`fect, it means to make something perfect. For example, “I want to per`fect my English” means “I want to make my English perfect”. Make sure you stress the right syllable. It can be the differece between different parts of speech. This has been today’s daily tip. Till then, tomorrow, for another tip on learning English.
常见问题
为什么同一个英文单词有时是名词,有时是动词?
因为音节重音位置不同:重音在前多为名词或形容词,重音在后多为动词。
如何判断像 'perfect' 这样的词是形容词还是动词?
听重音位置:'PER-fect'(首音节重读)是形容词,意为“完美的”;'per-FECT'(第二音节重读)是动词,意为“使完美”。
非重读音节在发音时有什么特点?
非重读音节通常发音更轻、更短,且其中的元音常被弱化为 /ə/ 或 /ɪ/ 等模糊音。
