  Let me introduce you to our head TA, Mara Daniel,
  我来给大家介绍下我们的首席助教 玛拉·丹尼尔
• 
  
  who's recently Mara Baraban.
  她最近才冠了夫姓"巴拉班"
• 
  
  So Mara's going to be the person who will see you after class
  玛拉将是你们的课后辅导老师
• 
  
  and she will take the problem sets that you have submitted before class
  她会批改你们上课前交给她的作业
• 
  
  and she'll give you the graded ones after class.
  课后她会将批改后的作业发还给你们
• 
  
  Okay? That will be sorted up, it'll be up there.
  明白吗 作业要放整齐 就放在那里
• 
  
  So you should drop the homework before you come into class,
  所以你应该在进教室之前交作业
• 
  
  rather than furiously work on it during class,
  而不是在上课的时候乱写一通
• 
  
  and the solutions will be posted the same afternoon.
  作业答案会在当天下午发布到网上
• 
  
  So there is not much point in giving homework that's late.
  所以作业交太晚的话就没有什么意义了
• 
  
  But once in a while, you know,
  但有时候呢
• 
  
  you will come up with a reason that I just cannot argue with.
  你们确实会想出一些我无法辩驳的理由
