Questions & Answers about אני הולך לעבודה, ואחר כך אני חוזר הביתה.
In Modern Hebrew, you normally do not use a separate present-tense to be in a sentence like this. So אני הולך is a complete present-tense expression by itself.
To an English speaker, it may feel like I going, but in Hebrew it means I go or I am going, depending on context.
In Hebrew present tense, verbs usually show gender and number, but not person. That means הולך is simply the masculine singular present form, and it can be used with אני, אתה, or הוא, depending on the subject.
So:
אני הולך = I go / I am going for a male speaker
אתה הולך = you go / you are going to a male
הוא הולך = he goes / he is going
A female speaker would say:
אני הולכת לעבודה, ואחר כך אני חוזרת הביתה.
