有趣的美术课

下午我们最后一节课是美术课，老师提前通知我们要带好美术课上要用的材料有：白纸，双面胶、蜡笔、和一双一次性筷子。

In the afternoon, our last class is art class. The teacher informed us in advance that we should take good materials for art class: white paper, double-sided tape, crayon, and a pair of disposable chopsticks.

上课时，看见老师手里拿着一面用蜡笔画着星星，一面用蜡笔画着像四周发着光的图片。中间用一根小木棒撑起来的小旗。老师拿着小旗轻轻一搓。我们很奇怪看到星星在发光。老师告诉我们做法，先把白纸对折，在对折的白纸中间画一个大大的星星涂上自己喜欢的颜色，在翻过来画上发着光的线条，颜色可以自己搭配。画好以后把纸打开，用双面胶粘在一次性筷子上固定，再用胶水把两面合起来。正反两面的图片要对准位置。这样会闪光的星星就做好了。

In class, I saw the teacher holding a crayon to draw the stars, and a crayon to draw a picture like the light around. A small flag with a small stick in the middle. The teacher took the flag and rubbed it gently. We are surprised to see the stars shining. The teacher told us how to fold the white paper in half, draw a big star in the middle of the folded white paper and paint the color you like, and turn it over to draw the line with light. The color can be matched by yourself. After drawing, open the paper, fix it on the disposable chopsticks with double-sided glue, and then close the two sides with glue. The pictures on both sides should be aligned. So the stars that will flash are ready.

老师告诉我们这叫视觉暂留。 还告诉我们动画片就是叔叔、阿姨们费了很多精力，用很多张图片叠放在一起，再快速的打开，才有我们以为本来就能动的动画片。

老师还给我们展示了一面是大树，一面是苹果，这样快速的转动就让我们看到树上长了许多的苹果。让我们展开想象，还有什么样的两张图放在一起就变成另一张新图。我做了一辆汽车在公路上快速的行驶。有的是小鱼在鱼缸里游泳，有蝴蝶在花丛中起舞。小猫正在吃小鱼。看着一张张生动的图片，每个同学兴趣都特别高。做的很认真，不知不觉就到了下课的时间了。

The teacher also showed us a big tree on one side and an apple on the other, so that we could see a lot of apples growing on the tree. Let's start to imagine what other two pictures together will become another new one. I made a car to drive fast on the road. There are small fish swimming in the fish tank, and butterflies dancing in the flowers. The kitten is eating the fish. Looking at a vivid picture, everyone's interest is very high. Do very seriously, unconsciously it's time to finish class.
