[7][小芋头]简单英语语法,I stayed wide awake,concentrating on taking
1、I stayed wide awake,concentrating on taking the curves smoothly.此句中“concentrating” ing形式的语法?后面半句不是从句吧?
2、The instant the truck stopped I jumped out and ran forward,fearing the worst.此句中“fearing”,
3、I covered the elk with a tarp and sat down near it,wrapping myself in blankets.此句中的“wrapping”,

答案

逗号后面是现在分词短语作伴随状语,不是句子.

答案同1.另外,stopped后面应该加逗号.

同上.
