at your English because you stop, you are sure to fail. 【小题10】are→ were
答案：
(答案→)are→ were
解析：
【小题1】You said in your letter that you are always trying to improve
主语从句中的谓语动词said为过去时，宾语从句也应用过去时，故are→ were。
【小题2】your English, and your English teacher didn’t appear to appreciate
前后分句的关系为转折关系，故and → but。
【小题3】your efforts. So you felt disappointing and lost the desire to learn
主语为You，应是感到失望的，故disappointing → disappointed。
【小题4】English. You know why teachers are busy and maybe your teacher
know后的宾语从句叙述的是客观事实，应用that引导或省略that，故去掉why / why→ that。
【小题5】is struggling to provide personal attention with all the students
provide sth for sb故with → for。
【小题6】in their class. In my opinion, it is a fact of life that sometimes
in their class 与本句中的your teacher矛盾，故their → your。
【小题7】people’s hard work went unnoticed. Though it is nice to receive
这里叙述的是客观事实，应用一般现在时，故went→ goes。
【小题8】encouragement and support, parts of growing up is learning to be
系动词为is，parts应为单数，故parts → part。
【小题9】motivated and study independent. So keep on working hard
study为动词，应用副词修饰，故independent → independently。
【小题10】at your English because you stop, you are sure to fail.
Because后两个句子，应将you stop前加上if。故在because后加if。
