英语翻译亲爱的外教老师,我的英文成绩真的是烂到了极点,你所说的,我只能听懂百分之二十,对于你所问我的问题,我更是回答不出

Dear foreign teacher, I am really poor at English and have got low grades in English all the time。 I could only understand 20% of what you taught to us, and I could not even answer your questions。 I feel very sorry for that。 The only thing I can respond you is that I will try my best to study English well。
