问题 解答题

体积与容积表示的意义相同.______.

答案

容积与体积是有着密切的联系,即它们的计算方法都是一样的(都用体积公式加以计算).但体积与容积是两个不同的概念,它们的区别有三:

1、意义不同.体积是指物体所占空间的大小.容积是指容器(杯子、盒子、油桶等)所能容纳物体的大小(即内部体积).

2、度量方法不同.计算体积时是从物体的外面去测量.比如:计算用玻璃做成的长方体金鱼缸的体积,就要从外面去分别测量出长方体金鱼缸的长、宽、高的长度.如果要计算这个长方体金鱼缸的容积(或容量),所需要的数据,就必须从金鱼缸里面去测量,因为做金鱼缸的玻璃是有一定厚度的.

3、计量单位不同.计算物体的体积,必须使用体积单位“立方米、立方分米、立方厘米”等.计算容积一般使用容积单位“升、毫升”;但计算较大物体的容积时,也拿体积单位“立方米”来通用,因为升和毫升只限于计量液体,如桶装的汽油、小瓶装的药水.

故答案为:×.

A man died and was on his way to another world, either heaven (天堂) or hell (地狱). He saw an extremely grand palace half way and the owner of the palace asked him to stay and live in the palace.

The man said, “I have been working hard during my life and now I just want to eat and sleep without any work.”

The owner of the palace said, “If so, there is nowhere else better than here for you. There is plenty of seafood and delicacies (美味佳肴) in my palace, and you can eat whatever you like without anyone stopping you. And nothing needs to be done by you.” Then, the man settled down (安定) in the palace.

At the beginning, the man felt very happy at the cycle of eating and sleeping. But gradually, he felt a bit lonely and void. So he went to the palace owner and said, “It is very bored to live by just eating and sleeping every day. Now I show no interest in this kind of life any more. Could you help me find a job?”

The owner replied, “Sorry, there is no job here at all.”

After another several months, the man could not go on with the life and went to the palace owner again, “I really can not stand this kind of life any more. If you do not offer me a job, I would prefer to go to hell instead of living here.”

The owner of the palace smiled contemptuously (蔑视地), “Do you think it is heaven here? It is actually hell!”
