After dinner, my mother is washing dishes, my father is watching TV, my grandfather is reading newspapers and I am building blocks.

After class, in the classroom, Mingming is sleeping, Honghong is looking in the mirror, Qiangqiang is talking to other students, and I am reviewing what I learned in class.

In a tough environment, we can learn to be strong; We can feel happy in a comfortable environment; In a dangerous environment, we can learn to be calm; In a safe environment, we can enjoy comfort.

Happiness lies not in having more money, but in being rich in spirit. Courage is not recklessness, but action after calm analysis.

The prosperity of a country depends not only on its strong economy, but also on its national defense strength. The proof of physical phenomena lies not only in rigorous reasoning, but also in bold imagination.
