Today is father's day.I've done a lot of things for my father.In the morning,I bought him a wallet as present.After that,I went to the market to buy some food stuff and cooked a delicious meal.In the evening,I sent the present to my father and wished him happiness.My father was happy that I was no longer a children and I became more sensible.I would not know how hard parents are if I had not cooked the meal.I sware I will study much harder and return them in the future.
明显是过去了的事,要是用一般现在时会很奇怪的,所以我用了一般过去式和过去完成时,其中一句用了虚拟语气,我觉得这样文章看起来会更加自然
