卒業までにドイツ語を話せるようにはなっていないと思うって英語でなんて言うの？

"To be fluent" is to have a high intermediate or advanced level understanding of the four language learning skills: reading, writing, listening, and speaking. We frequently use this term to talk about language capacity in American English. I hope that this helps! :)

There are three parts to this statement. The first being that there is a lack of confidence in a certain aspect of ability. This being the ability to speak a foreign language. The examples are " I am not sure," "I do not anticipate," and "I cannot see me." The second part is saying what it is that you have a negative opinion of. In this case it is ones ability to speak German. Finally the last part of the statement is a time frame. And in this case it is before the person graduates.

It is not enough time to be able to speak fluently by the time you graduate.

To say "I'm not confident" This would be mean your unsure and don't think you will be able to speak German fluently by the time you graduate.

To speak any language other than your mother tongue at a fluent level is to reach an advanced and native-level of speaking in your language studies. The fuller explanation above will tell the person you are talking to, that you don't think that you will speak German at a fluent level once you graduate. Also, by adding "but I do think it will be to a very high level," you are indicating that your German speaking skills will be at a very proficient level when you graduate.

To be fluent in a language means you are able to speak a language, other than your Mother tongue, very easily and confidently. I often think a good definition of fluent is when you can speak a language so well you can convey your sense of humour. Therefore as most people graduate when they are still young, generally they have not yet built the confidence to speak a language fluently. It requires experience and time which comes perhaps a few years after graduation if you get more chances to travel to the country where that language is spoken.

You are studying German right now at school. You might be able to read and write by the time you graduate, but you don't think you will be able to speak fluently in German. You want to explain that you don't think you'll be able to speak German by the time you graduate?
