1.stay low to the ground.译这个句子,另low 是什么词性?to呢 2
.i listen to the radio while i 'm eatin my breakfast.请问表示一边.一边不是要用as吗?此处怎么用了 while

Answer 1

stay low 中为系动词,为形容词,构成系表结构,意思是：俯身；to为介词,这来可以翻译为：向,往,到.
【区别】when,while和as的区别：when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词.并且when有时表示“就在那时”.例如：When she came in,I stopped eating.她进来时,我在吃饭.(瞬时动词) When I lived in the countryside,I used to carry some water for him.当的住在农村时,我常常为他担水.（延续性的动词） We were about to leave when he came in.我们就要离开,就在那时他进来了.While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生（或者相对应）.并且while有时还可以表示对比.例如：While my wife was reading the newspaper,I was watching TV.(was reading是延续性的动词,was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球.（对比） As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生；as也可以强调“一先一后.例如：We always sing as we walk.我们总是边走边唱.（as表示“一边……一边”） As we was going out,it began to snow.当我们出门时,开始下雪了.（as强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间）
