1. Joyce could read and write "when" she was three.
Joyce could read and write "after" she was three.
Joyce could read and write "before" she was three.
Joyce could read and write "while" she was three.
Joyce could read and write "since" she was three.
以上均合文法和邏輯。
但主要子句用了過去式(could ...),則表示Joyce現在已經沒有那個能力了,或已經不在人世了。
