The spelling of the third person singular form of the simple present:
All the verbs take an "s" in the simple present when conjugated in the third person singular (he, she, it) form:
Examples:

Simple Past Tense
We use the simple past tense to talk about things that happened in the past.
Examples:
The children visited the zoo last week.
The plane landed a few minutes ago.
Jerry dried his clothes in the sun.
For most verbs, the simple past tense is created by adding a d, ed or ied at the end of the word. These are called regular verbs. There are also irregular verbs which do not follow this pattern.
