这个问题烦恼了我很久..惭愧的是我每次翻了grammar book之后,就马上忘了...
还有,如果把 I have xxx+ed 和 I had xxx+ed,转换成YOU WE
THEY HE SHE IS,那么他们之间的用法请问有什么变化吗? |

看在我得空就帮你解答吧。
I have eaten. 意义是我已经吃了。
I had eaten before lunch.这里是指我在午饭前已经吃过了。
Present perfect 都是已经做过某样东西的意思。( have + PP)
Past perfect 就是present perfect的过去式,发生在某件事情前。 ( had + PP)
至于第几人称就用会基本公式
I you we they > have
He she it > has
past tennse = 全部用had. |

第一 had have很奇怪阿。。。只能当past tense 用吧? 这里的Had是 simple past tense哦。past perfect的话就是 I had had it before xxx . 酱就形成 Had + pp . 通常人家写成 I'd had ..
Have had 就是 present perfect 啊///
参考上面的post.
第三
isnt't it...这些东西是 question tag。 算是反问句吧。
用法呢。。靠感觉吧?
好像。。。She is so sexy, isn't she? 她很性感吧,是不是?
然后。。。没有 arent it / werent it的啦。 it 又不是 复数。 |
