Difference between something like 先週は... and 私は先週


For example, if I'm talking about something I did last week, is there a
difference in these two examples, or are they the same thing. For example, if
I plug in 本を読みました, or something like that into the .... ありがとうございます




As far as it is your own action, they are virtually the same.

  * 先週は本を読みました

has the implicit _I_ , so that it is equivalent to

  * 先週は私は本を読みました

which is more or less equivalent to

  * 私は先週は本を読みました

In all of the above, 先週は can be just 先週. The difference in these particular
sentences is that using 先週は (and particularly the first one) sounds like the は
being contrastive, so that something like _but this week..._ is expected
implicitly (or later in the sentence).
