Sure, I'd be happy to help you with these sentences! The choice of verb form depends on the subject of the sentence. In English, the third person singular subjects (he, she, it, and any singular noun) require the verb to have an -s ending in the present tense. For all other subjects (I, you, we, they, and plural nouns), the base form of the verb is used. Let's go through your sentences:

1. I like jam.
2. My friend likes horses.
