我们经常形容某人就像只有7秒钟的鱼，然而事实好像不是这样。
有人说金鱼的记忆只有7秒，7秒之后它就不记得过去的事情，一切又都变成新的，这个观点只是来源于一个爱情故事。
经过科学家研究证明，金鱼的记忆力至少有3个月，并且能够区分不同物体的形状、颜色和声音。实验方法是在水里固定一根杠杆，这根杠杆每天只有1小时是在水里的，训练金鱼在这个特定的时间里去推这根杠杆，如果金鱼能够记住这个时间，并能够将杠杆推动，它将获得食物作为奖励。结果是经过训练的金鱼很快就知道在准确的时间去推这根杠杆，以便获得食物。
We often describe someone like a fish for 7 seconds, but it doesn't seem to be the case.
Some people say that goldfish's memory is only 7 seconds, 7 seconds later, it doesn't remember the past things, everything has become new. This view is only from a love story.
Scientists have shown that goldfish have a memory of at least 3 months and can distinguish the shape, color and sound of different objects. The experimental method is fixed in the water lever, the lever is only 1 hours a day in the water, training fish at this particular time to push this lever, if the goldfish can remember this time, and will be able to leverage to promote it will get food as a reward. The result is that the trained goldfish soon know to push the lever at the exact time to get the food.
