Translation:Your tea will get cold if you do not drink it soon.
Can any one explain it to me....how it is that "wird" here means "become", "get" ....but in english translation it gets the meaning of future tense????? I mean german future is formed by "werden" + "verb in its invinitive". Is it just the effect of translation or it really has the meaning of the future tense????.........any explanation would be of use!!!
"Werden" is used both for future tense (werden + verb) and by its own for "to become" or "to get" (like in "to get cold"). "Wird kalt" can be understood as "gets cold" or "is getting cold", but note that present tense is often used in German instead of the future, this way it can be also "will get cold". I think the translation depends on the context: Your tea gets cold if you don't drink it soon - when speaking about tea in general, or Your tea will get cold if you don't drink it soon - when speaking about some specific situation.
Look at another sentence from this unit: Spiel mit mir, ansonsten spiele ich allein. "Spiele" implies future here: Play with me, otherwise I'll play alone.
Sorry if these explanations are not very good. This is my understanding, and I am neither a native German nor a native English speaker.
