I went to school and,without saying a word,bought a crips.这句话用的是什么句型,我初一

不应该是I went to school and bought a crips without saying a word。

句子中间部分将介词短语所做的伴随状语前置,做了插入语,形成分隔结构。
正常语序:
I went to school and bought a crips without saying a word.

Without saying a word, I went to school and bought a crips.
插入语不能是任何词语或句子,要看它在句子中的成份,只有非主要成份(定语、状语、表语、补语、同位语)能做插入语,原因是由于这些成分在句中仅起到补充说明作用,改变其在句中的位置不会影响句子逻辑结构,因此对于它们在句中的位置并没有严格要求,故可作为插入语前置或后置。

例句:
Jack, a friend of mine, is a good person. 同位语做插入语
Few people, however, can criticise this situation in perspective. 让步状语做插入语

【,without saying a word,】两个逗号之间是插入语 表强调
真正的主句 I went to school bought a crips追问

插入语可以是任何词语吗

追答

在英语中任何成分都可用两个逗号或破折号隔开成为插入成分,插入语可以使一个词、一个短语、或是一个句子。
