Understanding fluctuation, does it occurs to you? If so, how often?
Sometimes I have this issue, I just stop understanding with no apparent reason.
I've been watching the series Bad Education from BBC for a while, but today's morning I gave up watching it becouse I could understand a few words and frases. In the afternoon I tried again and then I succeeded, it was normal again.
yes ! It happens to me all the time , not only on understanding a new language, on other occasions too. like dating with a girl, you understand her well last hour, you made her can't stop laughing with you , she know your sense of humor,and all of a sudden, she look at you as a retard, everything you said are impropriety, all your jokes are silly and offensive. and it is the same girl with same me, I don't know what just happened, in China, we call this kind of situation as :"got a cutting-out on brain."
but I guess what I have experienced are not the same thing with you...
Recession for a while to some measure is often seen while you are reaching for something you want. Just relax for a while and go away for a while to clean your head. No worries, you will make an advance again before long.
This happens to me sometimes, too. Some days when I read Spanish or hear Spanish-speakers talk, I understand them perfectly. Other days, I feel like I went back to 5th grade Spanish again! Sometimes it even happens all of a sudden. The other day I was reading the Instituto Cervantes website to learn about the online classes they offer, when all of a sudden I forgot how to read Spanish! The website which I had been understanding perfectly was suddently gibberish. It was really frustrating!
It happens all the time and it's so frustrating. When that happens I need to take a moment and try after a while.
Fluctulation is inevitable for a English learner to master English. There is a Chinese old saying I am glad to share with you: 3 steps forward means 1 step backward.
As often as not, fluctuation occured during the course of my English learning which often disturbed me. My way is to keep moving and revise the mistake I made no matter what. My faith is as long as you can keep on, you can keep improving.
