人教版9年级英语5单元Section A 3a翻译

是不是这个Dear Anna,
If you have any idea where it might be, please call me.
I think I dropped it during the concert so it might still
be in the symphony hall.
I tried to call you but your mom said you were still at
your optometrist appointment  (I hope your new glasses
look nice!)
I really need it because I have a math test on algebra
tomorrow. It’s  crucial that I study for it because it
counts 30% to the final exam.
I’m really anxious because I can’t find my backpack.
Thanks,
 Linda.
