→ I don't know if/whether you can play football.
2. When changing a declarative sentence into an object clause, first add that (or not) before the clause and copy it. Of course, we should also pay attention to the change of tense
For example: she is a student
→ He said (that) she was a student.
3. When a special interrogative sentence is changed into an object clause, the interrogative word remains unchanged at the beginning of the clause, and then becomes the order of the declarative sentence. Of course, we should also pay attention to the change of tense
How old is he?
→ I wanted to know how old he was.
