Nobody could live without the sun. The sun gives us light and heat, and light and heat give us life. Without the sun, we would be in darkness.

Without light or heat, the earth would be very cold and there would be all snow and ice. Then all plants and animals would die.

We don't see the sun at night, because our earth is always turning round the sun, and only one side of the earth sees the sun.

When we see the sun on the side of the earth, it is day to us.

【參考譯文】

離開太陽沒有人能生存。太陽給了我們光和熱，而光和熱給了我們生命。沒有太陽，我們就會(huì)在黑暗中。

沒有光和熱，地球會(huì)太冷，所有的東西都變成了雪和冰。那么所有的植物和動(dòng)物都會(huì)死亡。

晚上我們見不到太陽，因?yàn)榈厍蚩偸抢@著太陽轉(zhuǎn)，只有地球上的一面能見上太陽。
