As for der, die, das = we have several rules to help you with memorizing them. For example, if a word ends with -heit, -keit or -ung, they are usually female words so you'd have to use die. The natural gender may also play a role, for example a male medical doctor would be "der Arzt" while a female medical doctor would be "die Ärztin". There are more such rules, but I do not recall them right now as I am a native speaker of German. One curious fact is that we have words which may have different genders, for example "Radio" may be "das Radio" or "der Radio". I believe this is a regional thing though. Regarding your other question: We have two future tenses, Futur I and Futur II. Futur I corresponds, at large, to the English "I will do"-type of future and expresses that someone will do something in the future. Futur II - and I would not worry about this one right now - corresponds, at large, to the English "I will have done"-type of future and expresses that someone will already have finished something in the future. I will give you the forms for Futur I and Futur II below: Futur I (example "gehen"): ich werde gehen du wirst gehen er/sie/es wird gehen wir werden gehen ihr werdet gehen sie werden gehen so it is simply "pronoun + corresponding form of "werden" + verb" Futur II: ich werde gegangen sein du wirst gegangen sein er/sie/es wird gegangen sein wir werden gegangen sein ihr werdet gegangen sein sie werden gegangen sein This is a bit more difficult at first, you use "pronoun + corresponding form of "werden" + partizip (the form you use for perfect tense) + the word "sein").

Using das, der, and die. You have to memorise it for each individual word! The future tense: 1. werden + infinitive 2. Just use the present tense. It works too.
