I'd like to suggest a simple way to help you learn how to express "past tense or perfect tense" in Chinese.

Once you use past tense or try to talk about something happened in the past, just remember to put “了” after Chinese verbs. For example, 我吃了XX，我玩了XX，我洗了XX  which means that you did something before. ( I ate xx, I played xx, I washed xx, respectively )

When you are trying to translate “perfect tense” into Chinese, you can put ”过了” after Chinese verbs, like 吃过了，玩过了，洗过了，看过了, which usually implies that something you have already done. ( I’ve eaten, I’ve played, I’ve washed, I’ve watched)

As you may understand, these are not an absolute rule and there are many exceptions, but in general, this can help native speakers understand that you are expressing something happened exactly in the past, not now or future.

You can try to organize this in your way and follow the suggestion, never feel frustrated, I know how weird or difficult to memorize them as I’m still struggling for English learning. J

（Tips：严格的说，你的句子翻译并没有错，但是在将英文翻译成中文的过程中要注意语境，和句子背后更深层次的意思翻译的效果会更好。要加强口语的练习，毕竟据我所知，对于英语国家的人来说，中文的发音会让他们很头疼。Ps:当然，如果你有练习的需要的话我可以帮助你。:-D）
