今天下午,我们在上美术课。课上到了一半,同桌孙舟轻轻对我说:“你看外边,天好黑。”我透过门上的玻璃看出去,天真的很黑,云层重重地压了下来,都快碰到教学楼的屋顶了。雨滴从离开云层,到滴落地面,大约要花多少时间呢?我好担心这时下雨,因为放学时路上都会是湿嗒嗒的了……美术老师让我们拉开窗帘,好好观察天的变化。所有同学的目光都望向那黑沉沉的天空。乌云像沾上灰尘的棉花般,贴在上面。还不时会划过闪电,传来雷声,好像在吓唬我们。 This afternoon, we are in art class. Halfway through the class, the same table Sun Zhou gently said to me: “I see the outside, the sky is very dark. ” I see through the glass on the door, naive black, clouds heavy pressure down, almost fast Encountered the roof of the school building. How long does it take for the raindrops to leave the clouds and drip to the ground? I’m so worried about the rain at this time because the road will be wet and damp when I get out of school ...... The art teacher let us pull the curtains and observe the changes of the sky . All classmates look to the dark sky. The clouds are dusty like cotton, affixed to it. From time to time will be across the lightning, thunder, seems to scare us.
