push是推的意思,pull是拉的意思,一些商城的玻璃门上都有这两个词.
look for 为“寻找”之意,它与“seach”没有可比性,因为search是及物动词,search sb意为“搜身”,search sth 意为“在.中搜查”.例如：They searched the guard.他们搜查那个士兵.He searched the pocket for money.他在衣袋中找钱.
search for 为短语动词,意为“寻找”,与look for同意,用法也很相近,一般可互换.search与search for 区分：They searched the room.他们搜查这个房间.
They searched for the room.他们寻找这个房间.
