用英语怎么表达?用英语怎么表达下面这几句话?1,我和姐姐没有看一整天的电视.2,我和姐姐一整天都没看电视.3,我从下午2

1.My sister and I didn't watch TV for the whole day.
2.My sister and I didn't watch TV the whole day.
3.I watched TV for 3 hours since two pm and stops now.
4.I watched TV since two pm till now.
第三个和第四个之所以没用完成时是因为楼主没有标明现在不看了距离看了三个小时后隔多久,如果是刚不看了,就要用完成时,楼下有说,如果现在一定七八点了,那就是表述过去的事情,对现在没影响,就用过去式可以了,区别过去式和完成时的根本是“这件事是否对我造成影响”譬如说我下午2点开始看电视,看了3个小时好累啊,现在5点,我不看了,那么看了3个小时对现在造成的影响是好累啊,我不看了.而 我下午2点开始看电视,看了3个小时电视演完了,现在5点,我不看了.这句话就不用完成时,因为看了3个小时这件事并没有影响我,我不看也不是因为看了3个小时.
多找例句体会一下,过去式和完成时是初中高中的重点.我现在做翻译,也经常会用到.

1. I and the elder sister have not watched an all day television
2 I and the elder sister one have not watched the television all day.
3. I start from 2:00 pm to watch the television, looke...

前两个翻译同意一楼的回答.　第三个是现在完成时I have watched TV for 3　hours from 2pm.第四个是现在完成进行时,表示已经开始的动作到现在仍在继续I have watching TV from 2pm.　

My sister didn't watch TV for a whole day
my sister and I didn't watch TV the whole day.
I had watched TV for 3 hours since 2 p.m. until now.
I watched TV from 2 p.m. till now

推荐一楼的回答，
