求一道选择题目,并说明理由
Joanna was tired.She_______ all day.
works
worked
has worked
had worked

求一道选择题目,并说明理由Joanna was tired.She_______ all day.works worked has worked had worked
选最后一个
因为was已经表示是过去发生的事,但是tired是因为工作了一天,所以工作一天是发生在tired前面的,是过去的过去了,所以用过去完成式.

had worked
前面是过去时,后面就是过去的过去
所以用过去完成

had work
因为是工作了一整天，持续性的用完成时
前面是was 后面用过去完成时

D
A，这是整天，肯定不是一般现在时
B，过去时也不是
CD中间。完成时，ALL DAY是个延续的时间，可以用完成时，又由前面的was tired可以知道，主句是一般过去时，从句就应该用过去的某一种时态，所以应该选D

had worked 工作发生在累前即过去的过去,所以用过去完成时

A she works all day (工作了一整天)一整天,应该用一般现在时,she 是第三人称单数,所以work后应该家"s"
