英语好的问几个问题

1 直接引语是直接引述别人的原话，原话用有引号，而间接引语是引述别人的话，不用引号。间接引语在多数情况下构成宾语从句。直接引语改为间接引语时，应该注意时态的变化：
1. 直接引语变为间接引语时，如果主句中的谓语动词是一般现在时或一般将来时，则间接引语从句的时态保持不变。例如：
He says, “I have finished my homework.” →He says that he has finished his homework. She will say, “I'll do it tomorrow.” →She will say that she'll do it the next day.
2. 如果主句的时态是一般过去时，从句的时态则应是与主句时态相应的过去时态。①一般现在时→一般过去时；②一般过去时→过去完成时；③现在进行时→过去进行时；④现在完成时→过去完成时；⑤过去完成时→过去完成时（不变）；⑥一般将来时→过去将来时。例如：
The girl said, “I'm sorry for being late for class.” →The girl said that she was sorry for being late for class.
He said to me, “I am writing a letter.” →He told me that he was writing a letter.
3. 直接引语如果是客观事实或真理，变为间接引语时，从句时态不变。例如：
The teacher said, “The earth moves around the sun.” →The teacher said that the earth moves around the sun.
另外，时间、地点、人称等一般要作相应的调整。
直接引语变为间接引语，应注意几种形式：
1．直接引语是陈述句，改为间接引语时，要将这个陈述句改为宾语从句，其连接词要用that(可省略)。
