直接引语的时态可以是什么

可以是任意时态,关键是从直接引语句子发生的时间和谓语动词的特征来判断.如：
1. I said, "I am a teacher."
2. I said, "I was a teacher when I was young."
3. I said, "I will work hard in future."
4. I said, "I've never been to Beijing."
5. I said, "I'm sleeping now. Please don't disturb me."
6. I said, "I was reading a book at 8:00 last night."
7. I said, "I had finished my homework when I went to bed yesterday evening."

一般现在时、一般将来时、现在完成时时 、现在进行时 、过去完成时（这个变成间接引语时不变）
