It is possible in conversation as rarely people will correct you, but in writing, it is correct and better to say: "People much prefer to take their holidays in summer."

"Go to sleep." means what it says. It means to fall asleep supposedly in a bed, but it could be anywhere. However, some people say "Go to sleep." to tell someone to go to bed AND sleep. This is because they assume that someone would sleep in a bed. If you told your friend to go to sleep, they prpbably would not stand upright and sleep on their own two feet whilst standing. They would go to their bed and sleep.

"It's very cold" is correct because you are describing 'it' which in this case would be the weather. Here, the word 'cold' is an adjective. If you want to be more specific you can say: "The weather is cold." "There's a lot of cold." would not be correct as the word 'cold' in this sentence cannot be used as a noun. A sentence where 'cold' can be used as a noun is shown here: "There's a lot of fun activities you can do in the cold." The 'cold' is now a noun that means a low temperature; a cold environment; cold weather.

This language is not friendly at all and is, in actual fact, threatening. "I dare ya" The word 'ya' is a slang term for 'you' so it actually means "I dare you." This phrase is used when the speaker is challenging the other person to do something; usually something they don't want to do. It is a taunt. "your head blown off" This means that the person's head will be decapitated completely. "servin' twenty" This is meant to be "serving twenty" and it means to serve twenty years in prison. "All of them are going down the same road either dead or servin' twenty." This means that all of them will be dead or in jail with a twenty year term.

"Did you use to get it done often?" This question is in the past-tense. The person asking the question is wondering whether or not the other person USED TO complete a particular task often. It implies that the person does not do the task often any more. Example: "I didn't do my homework again." "Did you use to get it done often?" "Yes, but I have become lazy." *Note: "Did you used to get it done often?" is wrong because the auxiliary 'did' should not be used with an -ed marker in a question. Compare: "Was he used to playing tennis all day?" "Did he use to play tennis all day?" "Do you get it done often?" This question is in the future-tense. The person asking the question is wondering whether or not the other person completes a particular task often. Example: "My homework is so difficult. I don't know if I can get it done this time." "Really? Do you get it done often?" "Go get something done!" This is a command. It is used to command someone to omplete a task or to do something in general that is productive. Example: Mark did nothing except playing video games all day, so his mother said angrily, "Go get something done!" Finally, he arose from the couch and took out the rubbish.
