Don't sweat it!Grammar is just a rule to correct your oral and written expressions,so it'd be important sometimes.But you don't need to worry about it when you have a good sense of language(语感),take me for an example,I don't think my English is excellent,but I can still communicate with native people and have no difficulty.And my good sense of language can account for that,as a matter of fact,my grammar really sucks,I even don't know what is subject,what is object.The conceptions of grammar really give me headache,I tried many times to learn grammar,but I failed.But my sense of English can make up for it. 欢迎交个朋友,我的QQ是1191860459
