(2)discover意为“发现”，指发现的对象是 本来存在的。 find意为“找到”，强调结果。 invent意为“发明”，发明的对象是以前没 有的东西。3. some leaves from a nearby bush fell into the water and remained there for some time. (1) nearby adj. “附近的“，e.g. he works in a nearby factory. (2)leaf 的复数形式为leaves (3)remain 表示 “继续留在某处” e.g. how long will you remain here?
