（二）can do改为could do
当直接引语中的谓语动词含有情态动词can的一般式时，转为间接引语后，要把can改为过去式could，如：
He said to Jane, 'I can work in the garden.'
He told Jane (that) he could work in the garden.
【注意】
如果是否定句，改法是一样的，只要把can改为could，如：
He said to Jane, 'I can't work in the garden now.'
He told Jane (that) he couldn't in the garden then.
（三）may改为might
当直接引语中的谓语动词含有情态动词may的一般式时，转为间接引语后，要把may改为过去式might，如：
He said to Jane, 'I may go to your school soon.'
He told Jane (that) he might go to her school soon.
【注意】
如果是否定句，改法是一样的，只要把may改为might，如：
He said to Jane, 'I may not go to your school soon.'
He told Jane (that) he might not go to her school soon.
三、一课一题
根据本课的重要语法点，让我们来练一练吧，请用把下列句子改为间接引语。
1. Mary said to Tom, 'I will take you to Paris next month.'
2. Kitty said to her father, 'You can pick me up at five this afternoon.'
3. Bobby said to his sister, 'Our mother may buy you a new dress.'
