This is the short written form of have, stuck onto the word before it: I've, you've, we've, they've. Most of the time it is the helping have that builds the present perfect — I've finished, they've gone.

This這 is是 of have have 的 the short written form書寫縮短形， stuck onto黏在 the word before it前面那個字上：I've、you've、we've、they've。 Most of the time大多時候， it它 is是 that builds the present perfect蓋出現在完成式的 the helping have那個幫忙用的 have——I've finished 我做完了、they've gone 他們走了。

In speech almost everybody says it this way, even careful speakers; the full have would sound oddly slow. In writing you use 've in messages, dialogue, and friendly prose. School essays and formal letters often still want I have.

In speech在口語裡， almost everybody幾乎每個人 says it this way都這樣說， even careful speakers連講話謹慎的人也是； the full have完整的 have would sound oddly slow聽起來會慢得奇怪。 In writing在書寫裡， you你 in messages, dialogue, and friendly prose在訊息、對話和輕鬆的文字裡 use 've用 've。 School essays and formal letters學校作文和正式書信 often常常 still仍然 want要 I have。

Though actually, I've can also be the have of owning something (I've no idea, I've a meeting at three) — that owning use is more British, and a bit old-fashioned in American English, where people prefer I have or I've got.

Though actually不過其實，I've also也 can be可以是 of owning something擁有東西的那個 the have have（I've no idea 我不知道、I've a meeting at three 我三點有個會議）—— that owning use那種擁有的用法 is more British比較英式， and in American English在美式英文裡 a bit old-fashioned有點過時， where people美國人 prefer比較喜歡 I have or或 I've got。

You cannot start a question with 've: we write Have you…?, not 've you…? After a name or a noun you may see it (The kids've left), though some teachers dislike that in writing.

You你 cannot不能 with 've用 've start a question開始一個問句： we我們 write寫 Have you…?， not而不是 've you…?。 After a name or a noun在名字或名詞後面， you你 may see it可能會看到它（The kids've left 孩子們走了）， though不過 some teachers有些老師 in writing在書寫裡 dislike that不喜歡這樣。
