1. 有标点的地方常是断句所在。

如: John Smith, /our teacher,/ came in/ with a book in his hand. Our teacher 前后逗号隔开，那么一般读的时候这也需要断开。

2. 一个功能可能是断句所在。如： John Smith, /our teacher,/ came in /with a book in his hand. 从另一个角度讲our teacher 做的是同位语，因此作为一个语调群。 Came in 做谓语With a book in his hand 做方式状语， 因此要放在一起作为一个语调群。

3. 分句常是断句的地方，如： He did not come to work yesterday/ because he was seriously ill. 但是具体地还是要看录音中是如何读的。比如： He did not come to work yesterday/ because he was seriously ill. 这个句子的两个分句还可以划分为： He/ did not/ come to work/ yesterday/ because/ he /was seriously ill.2读英语怎么断句根据意群断句。ps：意群可以是一个词，一个词组或短语，也可以是并列句的一个分句或复合句的一个主句、从句等等。 【例】(意群与意群间断句) 现将句子划分意群的一般原则归纳如下：

1. 名词词组1)冠词+名词，例：a country2)名词+名词，例：coumrade Li3)指示代词+名词，例：this book4)形容词+名词，例：natural science5)作形容词用的名词或分词+名词，例：New Year’s Daythe working class6)数词+名词，例：thirty-two note-books7)数词+数词，例：223--two hundred and twenty-three8)不定代词+名词，例：some ink2.介词短语，例：from now onwith an effort3.副词短语，例：day and nightfirst of all4.副词+介词短语，例：early in the morningfar into the night5.副词+动词，或动词+副词，例：quite understandstudy hard
