1. (2022九上·通榆月考) 随着年龄的增长，学校的课外活动丰富了许多，我们的关注点也增多了。刘兵给他的笔友赵明写了一封信，谈了谈他现在的课外活动和过去的课外活动相比有哪些变化，并说出了感受。请你根据提示将其补充完整，每空不超过三个词。

Dear Zhao Ming,

How is it going? As we grow, our after-school activities and what we care about are becoming more and more. I used to watch TV or play computer games at home.

And I used to only care about my own feelings and never care about others.

But now, I often volunteer to help people who are . And I usually talk with my parents that they can know my feelings. Now, I think about not only but also others. This makes me happy. We are growing up. If possible, we should do more meaningful things. Do you with me?

Please write to me to talk about your after- school activities.

Yours,

Liu Bing
