My Weekly Routine and a Memorable Weekend

一、一般现在时：日常习惯

Every day, I wake up at 6:00 a.m. After breakfast, I ride my bike to school. My father is a farmer, and my mother is a teacher. We live in a small village with my sister. This morning, I was doing my homework when my friend Tom called.

二、一般过去时：过去事件

Last Sunday, I visited my grandparents in the park. We had a great time fishing at 8:00 a.m. and rowing at 10:00. In the afternoon, I played basketball with my friends. It was so funny!

三、现在进行时：当前活动

Right now, I am reading a book in my room. My sister is drawing a picture, and my parents are cooking dinner. Look! The cat is chasing a ball of yarn.

四、现在完成时：过去持续到现在的动作

Since I started playing ping pong 2 years ago, I have become really good at it. My friends say I am a "ping pong champion" now. I have also learned to save water and energy at home.

写作提示：

时态选择：

根据动作发生的时间选择时态。一般现在时用于描述习惯性动作（如每天起床、上学）；一般过去时用于描述过去特定事件（如上周末的公园活动）；现在进行时用于描述当前正在进行的动作（如现在阅读、画画）；现在完成时用于描述从过去持续到现在的动作（如学习乒乓球、节约能源）。

时间状语：

使用时间状语帮助区分时态，如"every day"（一般现在时）、"last Sunday"（一般过去时）、"right now"（现在进行时）、"since 2 years ago"（现在完成时）。

连接段落：

用过渡句连接不同时态的段落，使文章更连贯。例如："Last Sunday, I..."（过去时）与"This morning, I..."（现在时）之间可以用"while"连接。

通过这篇作文，学生可以系统地学习四个时态的用法，并通过实际语境加深理解。
