這裡, since ,因為它是寫的,輔助have ,如果隨後過去分詞過時doendapnida語法不正確。在這裡,如果您想說I picked them out ,則必須更改since when例子: I have had them picked out since high school. (我從高中開始就選擇了它。)例子: I picked them out when I was in high school. (我在高中的時候就選擇了它。) I've picked them out是一種現在時的完美時態,沒有給出特定的時間點或用於最近發生的事情。 is used when we are talking about the recent past or the past with no actual date/time given, therefore it could not be used with since becausesince is a time mark. Which is the case in the context of this clip. Ex: I've picked them out since yesterday.即使在此視頻的上下文中也使用該視頻,因此由於時間標記,因此無法將其與之配合使用。 is used when we are talking about the recent past or the past with no actual date/time given, therefore it could not be used with since becausesince is a time mark. Which is the case in the context of this clip. Ex: I've picked them out since yesterday. ( This is incorrect grammatically )
