一个不明飞行物体用英语怎么说

I've been 英语翻译I’ve been=I have been，比如I ‘ve been to Shanghai；但是He had been 不能等于He’d been.been 是动词 be 的过去分词。
I’ve been = I have been ，是 be 的现在完成时结构，常用来表示现在的某种延续状态，如：
I’ve been ill for three days. = 我已病了三天了。
另外 have / has been to + “地方”= 到···地方去过，如：
He has been to Beijing. = 他到过北京。
如果后面接副词，to 等等的介词可以省去不用，如：
We have been there. = 我们到过那里；
The girl has been here for a week. = 这小女孩来到这里已经一周了；
He had been 等于 He’d been。have 另两位说的很清楚了。
2. have been has been是曾经的意思。I have been to china
had been 一半都有另一个断句说明一个时间的定义 The build had been demolished before i come back.1.’ve=have
【一个不明飞行物体用英语怎么说】I’ve (I have) 是现在完成时，I’d (I had)才是过去完成时。
been是be动词（am，is，are）的过去分词，后面要加表语（系表结构）；
例：I am in New York.
改写为现在完成时am就要变成been：I have been in New York for 3 months.
懂了吗？1、I have been=I‘ve been是现在完成时
2、He had been=He’d been
3、been是be的过去分词，通常I‘ve been后面要跟一个to+地名（如果是地点副词如：here/there/everywere等等省去to），表示“我去过……”I’ve been我已经
1.是的I’ve been = I have been
2是的He had b=He’d been可以这么简写！
