Hallo at all,
There is a point that I want to talk about.
Sometimes we have questions because our feeling is another than that what the teachers say. We are not able to believe all what our teachers say. They also can make mistakes. That is human.
I think the difficult we students have is that not all our English teachers are native speakers. Most of my own English teacher are Germans and their English is a foreign language.
The last three month I also noticed that it is better to distrust what the teacher says. I think we students need some other locations, eg internet, other teachers, other students, native speakers what ever to ask our questions to get a better understanding.
I think we students do not want to quarrel with our teachers but we are thinking persons and we want to learn and so let us ask and argue with everyone we can. That is the only way to get as much information as we need to get our own opinions. That is the only way to become a thinking person with its own opinion.
I know that it is very difficult when we say here that our teacher said something and we do not agree with it. It is not easy for Alan (the only native speaker I can ask at the moment) to answer such questions, because he do not like to be an arbritator. I understand that. But please have a little bit understanding that we ask you when we are irritated or confused in what our teachers tell us (sometimes). We do not ask to say our teacher is wrong. I think we ask to make it the better way. I think we students only want to learn and we only can learn if we ask as many questions we have.
It might be easier to ask our questions without saying that we do not agree with that what our teacher said. If we ask it this way it might be easier to answer our questions without feeling like an arbritator. That is a little suggestion to make it easier for (or to?) the people who make this site to answer our questions.
Thank you for your understanding in our problem (I do not think it is a problem).
a very sceptical and curious person
