1.How can we avoid wasting our time?
The best way to avoid wasting our time is to plan things ahead of time and set priorities. When we plan or list down the things that we need to do for the next day, we will be aware and guided on what we need to fulfill the following day. For instance, journaling your priorities with a timetable like at 7AM you have to eat breakfast; at 9AM you have to do the laundry; at 10AM you run errands. When we are specific on what we have to do in the morning, afternoon, and evening, we will not tempt ourselves to waste time like scrolling on our social media accounts. If we regularly take time planning ahead, it does change our lives meaningfully.

2.Do you think time management is important?
Definitely! Most prominent and successful people in the world teach us the importance of giving value to time management, since time is the most precious resource we all have. As Warren Buffet said, he could buy all the material things that the world had offered but he could never buy time. That line alone is full of wisdom – it does teach us to value time as much as we value our lives because once time is gone, we cannot get it back. Well, I am not saying that we should always busy ourselves doing many things, what I mean by that is we have to make sure to cultivate a habit of time management so we will not waste this precious resource and by doing that, we can surely live a more productive and meaningful life.
3.How can parents help their children learn to manage time?
That’s a hard question! I’m not a parent yet so I do not have any idea about teaching children the importance of time management. Besides, my parents did not teach me anything about time management when I was a child. Also, I believe children could care less about managing time since they are more interested in playing. However, I suppose parents can simply educate their children about the importance of valuing time, like making them finish their homework first before allowing them to play. I am not sure if that is effective but that is the only way I can think of right now.
解析：粗体部分是很实用的固定表达，用来争取思考时间和总结。语法方面这一段的第三句刻意使用了一般过去时，第四句使用了比较级less和more. 注意用I believe和I suppose替换最常用的I think.
4.When does relaxing become a waste of time?
First of all, to relax is not a waste of time, it is the ultimate way to give our mind or our body a rest and we all deserve that. However, I think relaxation becomes a waste of time if it is done too much to the point that your work or your goal is already sacrificed. For example, instead of relaxing for an hour by surfing the net, you end up spending two or more hours on the internet which puts off your work that you are supposed to finish during the day. In that case, relaxation becomes bad and I believe we can avoid that when we draw the line between relaxation and wasting time.
