ask for help是一个完整的动词吗?应该ask sb for help 或ask for help from sb吧
但总觉得ask for help 挺完整的..但既然有这种题目In the dark street ,there wasn't a single person___she could ask for help的话有ask sb for help 或ask for help from sb两种都可以 也至少说明ask for help 不完整 我说的对吗
有ask sb for help 或ask for help from sb两种都可以的意思是用ask sb for help 横线上可以填that 或whom 用 ask for help from sb的话填from whom
