Can someone help me please?(English homework)?

Is there a chapter or section that you can refer to when conjugating verbs , proper nouns etc.....The word in bold is the what ? , is it , the Noun, the verb , etc? Once you know that, you can go from there in determinging how to conjugate, ( how to use it in a sentence with other words) . You can also, look at the sentence and ask yourself, what are they trying to say? How can you get the same idea across ? Then you need to also change the word in bold to match the tense of the sentence and put it in. The tense refers to, past, present, future, etc...
