到惩罚。如果一个动物碰巧被车辗过，人们会很难过的。
加拿大人喜欢动物有很多理由。其中之一可能是：他们的亲属关系并非如我们那样地接近。当孩子长大后，他们离开父母，开始自己的生活。然后，年老的会觉得孤独。但宠物可以解决
这个问题。他们可以成为好朋友，从来没有离开他们。

To find out whether bees can see colours, the following experiment is made. A
table is put in a garden, and on the table is a blue card with some syrup on it. As soon as one bee finds the syrup, many more come to it one after another in a short tome. It seems that one bee is able to tell the news of food to the other bees in their “home”. After a moment, the blue card with syrup on it is taken away. Instead of this card, a blue card is now put on the left side of the first feeding place and a red card to its right. Nothing can be seen on the two cards. Very soon bees arrive again, and fly straight to the
blue card. None go to the red one.
要了解蜜蜂是否可以辨别颜色，进行下面的实验。花园里摆上一张桌子，桌上放着一块涂了糖浆的蓝色卡片。只要一只蜜蜂发现糖浆，短时间里就会有更多的蜜蜂一个接一个到来。看来，一个蜜蜂能把食物信息传递给“家”中的其他蜜蜂。过一会儿，拿走涂有糖浆的蓝色卡片。现在把替换了的蓝色卡片放在第一次喂食地点的左侧，再放一块红色卡片到蓝色的右侧。两张卡片上看不到任何东西。很快蜜蜂再次到来，直接飞向蓝色卡片，没有一只飞向红色卡片。
