Question

改错题，求助：为什么？？？处为问题，正常答案是改为have，去掉had行不行？

I often quarrel about my mother over whether I can watch TV after school. She holds view that senior three students have to make fully use of every minute to work hard at their lessons. It seems to me that once I am allowed to do that, I’ll unable to control myself and forget all about my study. She also thinks it is bad for my eye. But I really can’t accept her ideas. In my opinion, watch TV can set my mind at rest after a day’s hard works. Besides, it is important for us to know what ？？？had？？？？ happened both at home and at abroad. Thus, we shouldn’t be forbidden to watch TV.

Answer 1

您好。have +过去分词 为现在完成时，强调对现在的影响，而如果去掉，则为过去式，仅表示过去发生的动作。因此不能去掉，谢谢。

Answer 2

改 have是现在完成时
去had是一般过去时
就这点差别，想不通吗？
it is 是一般现在时，再根据前后文意思不适合用一般过去时
用现在完成时：指到现在 世界上发生了哪些事情，有掌握最新消息的意思。

追问

我知道现在完成时是过去的动作对现在产生的了影响，但是具体落实到题上就不会了，能否解释一下？O(∩_∩)O谢谢，增加悬赏5分O(∩_∩)O谢谢

追答

1.表示从过去某一事件发生到现在或将继续持续下去
2.过去发生的事对现在造成的影响
3.表示现在已经完成的动作
上面是现在完成时的三种用法

作者看电视时可以了解当当下世界各地发生的大事，这个事情已经发生了，同时也可能继续持续下去，比如台湾飞机打捞工作。

Answer 3

你在叙述的时候是用的现在完成时，意思是家乡和国外都发生了什么，你想要了解的当然是时事新闻吧，而且你知道的时候新闻事件必然已经发生过了。
另外我觉得还有几处用的不对，把正确的段落写在下面了：
I often quarrel (with) my mother over whether I can watch TV after school. She holds view that senior three students have to make fully use of every minute to work hard at their lessons. It seems (to her) that once I am allowed to do that, I’ll (be) unable to control myself and (will) forget all about my study. She also thinks it bad for my (eyes). But I really can’t accept her ideas. In my opinion, (watching) TV can set my mind at rest after a day’s hard (work). Besides, it is important for us to know what ？？？had？？？？ happened both at home and at abroad. Thus, we shouldn’t be forbidden to watch TV.
