Explanation:

When reporting sentences, we must pay attention to the following:

1. The subject of the reported sentence will change according to the context. For instance, in sentence 2 above, the subject is the same as the person reporting the sentence. However, in sentence 5, the subject is "he", the person who asked the question is "she", and the person reporting or the current speaker is "me".

2. We usually change the verb tense to the past of what was used in the original sentence. For instance, simple present to simple past, present perfect to past perfect, will to would, etc. Notice that in sentence 2, "would" did not need to change.

3. When we report a question, we must not maintain the interrogative structure. Therefore, we make the necessary changes, such as suppressing auxiliaries or simply moving them. Take a look at sentence 5.
