The carpet where he was warm and comfortable so he slept soundly.A. was layingB. was lyi

问题补充：

The carpet where he was warm and comfortable, so he slept soundly.A. was layingB. was lyingC. had laidD. had lied

答案：

易混淆词辨析题。动词lay表示“搁置、放”时，现在分词为laying,过去分词为laid；而lie作“躺”讲时，现在分词为lying,过去分词为lain，如其过去分词为lied,则含义为“撒谎”。此处为“躺的地方”，故用was lying。
