修改原因
修改前Last term I bit off more than you can chew and failed two exams.
修改后Last term I bit off more than I could chew and failed two exams.
词典常用 you 列出习语，让人误以为整句不能改。但代词和时态都要与具体句子一致：I bit off more than I could chew、she has bitten off more than she can chew。修改只把 you can 改成 I could。
Have a lot on your plate 也表示事情很多，但不带自责：I have a lot on my plate this week 只是说这周很忙。Bite off more than you can chew 则强调接下太多事情，高估了能处理的工作量。
