Answer:
 1. The manner in which action is presented indicates verb mood.
2. Time of action is indicated by verb tense.
 3. Whether the subject names the actor or the receiver is determined by voice.
Explanation:
The mood of a verb concerns the way it is expressed, the attitude of the speaker. For instance, if the speaker wishes to convey a fact, he will use the indicative mood. If he wishes to command or request, he will use the imperative mood.
Verb tense expresses a connection between the verb and the time when the action took place. If the speaker talks about something that happened yesterday, he will use the past tense. If he addresses something that will happen tomorrow, he will use the future tense.
Finally, voice expresses the relationship between the action described by the verb and the subject. If the subject is the one performing the action, we use the active voice. If the subject is the one suffering or receiving the action, we need to use the passive voice.
