| You said in your letter that you are always trying to improve your English, and your English teacher didn't appear to appreciate your efforts. So you felt disappointing and lost the desire to learn English. You know why teachers are busy and maybe your teacher is struggling to provide personal attention with all the students in their class. In my opinion, it is a fact of life that sometimes people's hard work went unnoticed. Though it is nice to receive encouragement and support, parts of growing up is learning to be motivated and study independent. So keep on working hard at your English because you stop, you are sure to fail. | 1. _____ 2. _____ 3. _____ 4. _____ 5. _____ 6. _____ 7. _____ 8. _____ 9. _____ 10. ____ |
