You may have (already been using) vs (been already using)

1.

諗下：你會講 I have done already my homework 定係 I have already done my homework?

家下只係由present perfect變成present perfect continuous，多左個 ing，already一樣係o個個位。

順唔順口唔係標準，亦要睇判斷者本身學到o既o野正唔正確。我只係好簡單咁做左一個實驗：
"You may have already been using" 用 google 查，結果：
約有215,000項符合"You may have already been using "的查詢結果
查"You may have been already using"，結果：
找不到和您的查詢-"You may have been already using"-相符的資料

唔信你都可以試下，記得要用英文quotation marks( "" )包住成段字串。

1. You may have already been using ...
不對

2. You may have been already using ...
對

其實You may have been already using ...比較順口
