1) Time flew in the blink of an eye. "Flown" is only used with the words have/has. Here are some examples: She has flown in from Dallas. (Has is used with the singular pronouns he/she.) They have flown over the Atlantic three times. (Have is used with the pronouns I/they/we.) 2)There’s a ( )woman with a little boy standing beside her , holding her hand tightly. This could be almost any adjective that exists. You have to think about how the woman is in your mind and use that adjective. Is she strong, tall, short, fat, happy, scared. or lonely? You can just pick one. 3). (putting away)the puzzled expression on my face, I gave them a warm and broad smile as to make them feel that they were welcomed. This does make sense. 4)This was our sweet, ( ) childhood . This is another question about an adjective, and it is kind of the same. You think about how the childhood was. Was it innocent, boring, or short? 5)Happiness could be looking at something beautiful. Do you mean to ask is this the definition of happiness? In that case, no. If you mean to ask if the sentence is correct, yes! 6) I was almost melted BY your smile. 7) Guilt, shame, and regret once again filled my being. I could do nothing but feel sorry. These three words need to be nouns, because they are completing an action. They are filling, and only nouns can complete actions. 8)I was always(be?) treated with respect If take out the (be), this is a correct sentence in past tense. If you want this to be a future tense sentence, you would write "I will always be treated with respect." 9) Before I drifted off to sleep, (and then continue the sentence.) One more thing. This post should probably be in the Notebook area, because that is where we can upload writings for corrections. This is the Discussion category, and is for talking about things or ideas.

Flow / flew / have flown. It's probably better to ask separate questions, or post your text in Notebook.
