I'm assuming you are trying to say,"type of payment upfront" which means that someone is trying to ask you what form (credit card, cash, checking, ect.) of payment will you be providing up front( before the service is rendered).

Who (capitalize the first letter of any sentence in English) wants to practice Spanish with me? I (capitalize) need "to" practice my English more. Thank you very much. A quien hablar espanol con mi? Yo necisito practicar mi espanol mas.

Does anyone want to speak English?

If you are talking about Professional licensing (Lawyer, Project Manager, Engineer, Medical, ect) you typically have to renew or recertify the license through continued educational courses an a fee. Accreditation is usually conducted with organizations that are required or want to belong to an organization and need to continually hold a specific standard/ level of achievement. It is never referenced to an individual. If you are talking about a drivers license, you typically have to 'renew' this as well.

I agree with Hibia. The best way to learn a new language both writing and speaking is to watch movies or shows. Here is a secret. Try to watch "KIDS CARTOONS". They tend to be a lower level English and usually speak slower because kids are trying to learn too! It makes it easier for you to try and follow along! A good series to watch is Sesame Street ( a kids show that focused on learning English and other fun stuff).

The difference in these two is so subtle, most people would use these interchangeably, usually with a meaning of "in addition" which would be the less formal way of saying both. If you want to get very detailed, to me furthermore introduces an additional concept as a straight fact, whereas moreover suggests that there is a perceived link between the additional information. More extreme versions of those sentences might read: 1) The car's acceleration performance is poor and the fuel consumption is extremely high. (The reader is left to draw their own conclusions based on these facts) 2) The car's acceleration performance is poor and what's more, the fuel consumption is extremely high. (The writer is possibly suggesting that this combination makes for a poor car) As I said, it's subtle and I would say it's definitely possible to imply the second meaning also with 'furthermore'.

Neither. It also would depend on the context that you are trying to ask the question. If you are asking in the context of day to day traveling (work, school, mall) you would ask "What's the cheapest way to commute back and forth to..(work, school, the mall). If you are asking in the context of traveling over long distances you would ask "what is the cheapest way to travel"...

Thank you is typically used in a more formal. Thanks is typically used when you are around your friends or family members.
