Present perfect 1

Hmm... They've already invented it. I wasn't understanding this description maybe half of the day. But picture take me key for it. People in the story talk about things that we know how modern. But thay talk about in the past many thousand years ago.

I can say today that We've already invented it. I'm about taxi, clocks too. That show how long may be time range for Present perfect. Also, two first tems say that focus may be on the past or on the present time.

 

 

No tense

I think possible to write it as:

• The taxi arrived, already // focus on the now
  
• The taxi arrived, finally // focus on the past

It's for show that common template is work and possible to use it too. But English like to use tenses more than it. Hmm ... ok, tenses determine time conditions by templates.

Negative

• I still haven't washed the dishes. // focus on the past
  
• I haven't washed the dishes, yet. // focus on the now
  

Regular ends

• most verbs, add -ed;
  
• when -e in end, add -d;
• when consonant and -y, delete -y and add -ied;
• when end single vowel and single consonant, double the consonant;
• when vowel and -y, add -ed [except pay, lay, say => paid, laid, said];
  
• when verbs ends vowel + consonant, double consonant + -ed [except if final syllable isn't stressed];
• when ends -l, double l + -ed [except North American English];

Irregular ends

 

Third form of the ends ... It's maybe equal for irregular past simple with all conditions.

Coomon

Each time Present perfect sets the connection between past and present. When an event isn't in the past, when it's affecting me now. If I feel it. There are two ways for set focus in this tense: for the past or for the present.

But if I can't unlink past and present, I must use it.

Feeling

No rules or terms here, only feeling. This time dangerous, unlimited obligations may be there. Shanke take me one tip more, how it may be when I will have many links in the present perfect.
