　答案及解析

9. is 改为 are。本句用 my picture 和 the prize 作主语， 是复数形式， 后谓语动词应和其主语保持一致。

8. calm 改为 calmed。在 and 连接的两个并列句中， remember 和 calm 为两个并列动作， 为过去时态。故 calm 改为 calmed。

7. but 改为 and。smiling 和 nodding 为两个并列动作， 在逻辑上无转折关系， 故 but 改为 and。

6. 删去a。catch sight of 为固定搭配， sight 前不加任何冠词。

5. as 改为 that。根据句子结构， so 应与 that 构成复合句， that 引导结果状语从句， 在此不能用 as 引导。

4. 此行无错。

3. that 改为 whether。根据上下文， 可判断本句意为“我是否成功没有关系”， 所以这里用 whether。

2. schoolmate 改为 schoolmates。因本句中有 all 一词， 所以 schoolmate 一词应为复数形式。

1. teacher 前加 my。根据下行 She said that she and my schoolmate all wished me success， 可判断 English teacher 应是特指。
