Therefore, I decided to do his best. After I got home, I stayed in my room, spend all my time reading the poem aloud. This morning when the Chinese teachers came in, my heart raced wildly but my face went red. Though I was quite afraid to stand before my classmates, I finally remembered that what to recite. Lucky, I made no mistake at all.
