(1)是的. (2)介词加名词一般作状语,如伴随状语,时间状语,地点状语等. (3)试举几例:I usually go to school at 8 in the morning时间状语.I stayed in my room地点状语 last Sunday.He passed by without a word伴随状语. 但愿能帮到您.
这是“介词+名词”的语法功能之一,尤其当这个名词是地点名词时,如:on the table / in the place / in school / at the airport / in front of the window....这些都是相当于一个地点副词。 但并不是说,所有的介词+名词结构都是这样
