【解析】

短文讲述了科学家对动物能不能分辨颜色做了一个实验。狗看到的颜色都是一样的，而猴子看到的颜色是不一样的。

1.细节理解题。文中提到了dog和monkey，很显然是两种动物。故选A。

2.推理判断题。根据第二段“The scientists put food in a red box, and do this every day. A monkey always goes to the red box to get food. Then the scientists put food in a blue box, but the monkey doesn’t go to eat it.”科学家每天把食物放在红色盒子里，猴子总是去红色盒子取食物。放在蓝色盒子里时，猴子就不去了。说明猴子能分辨颜色。由第一段“the American（美国的）scientists give（给）the dogs food. They put（放）the food in the box in the same color every time. The dogs see this color and go to eat. The scientists then give the dogs food in a box with another（又一）color. But the dogs go to eat the food, too.”说明狗不会分辨颜色。可推测科学家把食物放在不同颜色的盒子里，是想知道动物它们是否能分辨颜色。故选D。

3.细节理解题。根据“But colors are not all the same to monkeys.”可知，对猴子来说，颜色不都是相同的。就因为猴子能分辨颜色，把食物放在换了颜色的盒子里，猴子就不去了。故选D。

4.推理判断题。根据“Scientists（科学家）think that many animals（动物）can not see colors. The world（世界）is black and white to them. Can dogs see colors? Scientists want to know.”这篇文章讲述的是科学家想知道动物是否能够分辨颜色。故选B。

5.推理判断题。本文讲述的是科学家对动物能不能分辨颜色做了一个实验。这属于科学实验，可以在科学专栏里看到。故选A。
