Hello! "would" can be used in many ways. It is a word used to ask questions. Example: "Would you like to go to dinner with me?" "Would you like to go to the movies?" You can use "as" to compare things. Example: This dog is as big as a horse. or This good is as good as the food I make at home. These are just basic ways to use the words "Would" and "as." I hope this helps! Ways to use "if". If is another way to ask a question or telling someone how their action makes you feel. "If you come to dinner with me, I will be very happy" "What if I go to dinner with Cindy tonight?" "What if I do this? "What if I run to the gym?" Whether: "I am going to the gym whether you like it or not" - used in an indirect question. "I don't know whether she will be home or not" - expresses a doubt or a choice between ideas. -Dymon
