Sometimes I'm a little afraid that I cannot express myself well. As the willingness to be a gentleman, I would never want my expressions sound rude or weird. Basically I wish I could express precisely what I mean. And it would be much better that it sounds natural.
Reciting the words is always a useless way to learn English for me. I have less patience to do that over and over again. Reading is much more interesting and can increase the knowledge of common phrases and vocabularies quickly.
So is there any way to check if your expressions sound natural?
