　答案及解析

9. 此行无错。

8. a lot 后加 of。

7. am 改为 was。综观全文时态可知。

6. the 改为 one。由下文的another可知， 上文用one。

5. among 改为 in。“in my family”为习惯搭配， 意为“在我家中”。

4. Unfortunate 改为 Unfortunately。此处应用副词作状语。

3. watch 改为 watching。作句子主语需用动名词。

2. 删去 was。由上文句意可知“我现在不看电视， 而过去每晚都看电视”， 因此应用 used to do。

1. 删去 much。“I can’t watch much television”意为“我不能看许多电视”， 上下文逻辑不通。much 属于多余。
