Question

(I've been told)the sports meeting might be put off

可不可以用I've told 或 I was told
为什么答案选I've been told?

Answer 1

I've told不可以，因为这里“我”是“被告诉”，是告诉这个动作的受体，应该用被动语态。但I was told是可以的。但与I've been told 比较，前者只强调“被告诉”这个动作，这者更强调“已经被告诉”，是强调了动作的顺序性。具体应看语言的环境。

Answer 2

不可以。
I've told不是被动式，
I was told不是完成时。

Answer 3

你说的那句话牵涉到两个问题，1完成时态，2被动语态，却一不可。就跟二楼说的一样，I've told和I was told一起才对，完成时态的be就是been了！

Answer 4

在这句话当中,"I was told"也可以!只不过这种用法,native speakers更习惯于说:"Sb told me..."
如果要用"I've told..."则习惯于带说话的对象"you",也会加"before".
