请问是she didn't do her homework,yesterday.还是she didn't do her

以时态来说吧。其实这个概念很好懂的，　时间状语就用来是表示时间的词或词组 时间状语 一般现在时 every …, sometimes, at …, on Sunday, 一般过去时 yesterday, last week, an hour ago, the other day, in 1982, just now 一般将来时 next…, tomorrow, in+时间, 现在完成时 for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always, recently 过去完成时 before, by, until, when, after, once, as soon as 过去进行时 this morning, the whole morning, all day, yesterday, from nine to ten last evening… when, while 将来进行时 soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening 这么说明白么？
