My mother sells in the market every day. She usually wakes up at 6:30 a.m. She prepares breakfast and takes a bath afterwards. After dressing up, she eats her breakfast and off she hurries to the market. She works in the market till 6:00 p. m. when she returns home.
This passage describes what happens every day. The highlighted verbs are all in the present simple tense. The present tense is therefore used to express an action that is habitual.
Consider the following statements;
1) The sun rises in the east and sets in the west.
2) Water boils at 100 ° C.
3) A hungry man is an angry man.
4) A journey of a hundred miles begins with the first step.
The preceding sentences express what is always true.
Thus the present simple tense is equally used to show something that is always true.
Another use of the present simple tense can be seen in the following statements.
1) The seminar begins tomorrow at 9 a. m.
2) The soldiers leave for Bakassi next week.
3) The new government meets next week.
The verb forms are the same but for the 3rd person singular which end in either-s,-es, and or-ies.
So, always say
My mother (she) goes, to the market every day.
The dog (it) wags, its tail each time it sees its master.
The baby (he) cries when he is hungry.
My uncle (he) brushes his shoes very well.
