n.(名词)

base的基本意思是“底座,基础”,一般指具体有形的事物的底部、基座等; 也可用来比喻理论的基础或讨论的根据等。base还可作“基地”解,多指军事或工业基地。

base是可数名词,其前可加a或the,在句中可作主语或宾语。

v.(动词)

base用作动词是“把…建立在,以…为基础”的意思,指人们依据一定的客观规律或自己的亲身体验而得出的一定结论。base常用于非物质结构的基础,这个基础可以是物质的,也可以是非物质的。

base是及物动词,常与on连用,作“使建立在…基础上”解。常用于被动结构。

base常指有形的基础，侧重指构成或支撑某一具体物体的基础，也可指军事基地或用作比喻意义。而basis常指无形的基础，主要用作抽象或引申意义；

miptary base是指军事基地，economic basis and superstructure是指经济基础和上层建筑；

base和basis的复数形式都是bases，前者读作['beisiz]，后者读作['beisi:z]。

v.(动词)我的希望建立在这个新计划之上。

误 My hope based on the new plan.

正 I based my hope on the new plan.

析 base为及物动词。因此表示“建立在…之上”或“以…为基础”时不能说base on sth,而只能用base sth on sth 的句型。
