问题描述:

as与 as though区别
The old lady loves Tom___he were her son.
A.because B.as C.if D.as though
可是as同样有“好像”的意思,为什么不选择B?

as though
adv.
好象, 仿佛
as if好像,好似
as
adv.
同样地, 被看作, 象
prep.
当做
conj.
与...一样, 当...之时, 象, 因为
[域] American Samoa, 东萨摩亚
abbr.
[军] Air to Surface, 空对地

as 还有一种意思是”当作“
我个人认为选D
因为如果选B的话,应该是这样的
The old lady loves Tom AS her son

注意he后面的动词是“were”,也就是说这个句子是个虚拟语气,而as不引导虚拟语气.一般用as if或as though 引导虚拟语气
