You could simply ask "Can/could i have the recipe?"(if you wanted to know how to make the dish). If you want to be more specific about what is in a dish you could say"What ingredients does this dish/recipe contain?"

Here he means he is not enamoured at all. He is not happy with her nagging, he is more than a little annoyed. By using "less than" before what you are saying can make what you are saying less offensive, more diplomatic......in other words less direct. It's like an understatement where if we want to say something that is bad and we use words that are less strong or direct than the actual meaning implied. "He was less than honest with her."="He lied to her." "The investment was less than profitable."="The investment was a disaster."

All of your answers are correct. As Adelya says, they are all variations of "How are you," but I will suggest what I would say are the differences as follows; What's up? This could be used to mean "what is the matter?", or "What's up with you?" You are asking someone what is wrong, or what is worrying them. You are showing concern for them and eliciting a more detailed response of what it is that is worrying/troubling them. Informally though, it is normally used to mean "What's happening?", and generally replaces "Hello" , or "How are you?" as a form of generally greeting someone. "What's up?", I said to her. "Not a lot", she answered. What's new? As with the example above we could interchange this phrase/greeting. We could use it to replace "Hello", meaning "How are you?" Alternatively, we could say "What's new?" as an informal greeting asking the other person what has recently happened in their lives. You could answer "Not much, you?" How are you? Again this would normally be used as a greeting just making polite conversation rather than really wanting to know in depth how somebody is. It is often used if you have not seen someone for a while, so when you by chance see an old acquaintance in the street for example. Normally answered with "I am fine thankyou," or could equally say "Not bad, good to see you," or "Not bad, how about you?" The only situation where I can see that you would respond in depth is if your doctor asked you this and you would respond with your symptoms etc....that you came to see him/her with. How are you feeling? This greeting normally has an emphasis on the recipients health. You are inquiring about the state of someone's health. "How are you feeling now?", "oh, a bit better thankyou." "I heard you were feeling sick recently. How are you feeling now?" It could imply you were not feeling well a few days ago and the person asking this wants to find out if you are feeling any better now.

Has kept (present perfect) emphasises that Gwyn continues to keep/raise dairy cattle..if you say had kept it suggests it is something she did in the past, and that she no longer keeps cattle.

To say you are"on it" means you will take care of a situation. It means you are doing something that needs to be done, or you are trying to solve a problem. "You need to get your homework done." "Don't worry;I'm on it."

In your example "I'm going to hook up with friends" it means I'm going to meet up with friends. Did you ever hook up with any of your old friends when you visited your childhood neighbourhood? in other contexts it could also mean to work together with another organisation for a particular purpose: Micheal Jackson hooked up with Pepsi to promote his new album. You could also use the phrase to hook somebody up with something meaning to help them get something that they need or want: Do you think you can hook me up with some tickets for the rugby world cup? As Aaron said it can mean to start having a physical, intimate relationship with someone(normally casual).

You could say "Have you seen his response to me on twitter?" as response could imply an answer to a question or a reaction to a situation....you use respond to say something in return, a response is a reaction to the communication...or in this case your tweet.

I would say that we use SEE when we do something unintentionally, when we open our eyes it is not a deliberate act, we see without any conscious effort. Watch is used when we look at something that moves or changes for a period of time. It is more a continuous action of looking and observing. In terms of a movie, you could use both, but I would suggest there is a slight difference. Generally we use SEE for public performances of something, and WATCH for television at home. We are going to see the latest movie at the cinema tonight. Last night I watched a great documentary on the television. Did you ever see Elvis Presley live in concert? We watched a good movie yesterday implies more that we watched it on the television. We saw a good movie yesterday would imply more that you did so by going to the cinema.
