1、跷跷板用英语怎么说
The English term for "跷跷板" is "see-saw". See-saws are popular playground equipment that are usually made of a long plank of wood, with a fulcrum in the middle. Children sit on either end of the plank and use their weight to alternate up and down.
Aside from being a source of enjoyment for children, see-saws are important tools for learning the principles of physics. The up and down motion of a see-saw is dictated by the laws of motion and the balance of forces. The more weight one child puts on their end, the higher up they go, and the other child must either add weight or adjust their position in order to maintain equilibrium.
There are many variations on the see-saw theme, from the classic wooden plank to more modern designs made of plastic or metal. Some have handles or grips for added safety, while others are designed to spin or rock in addition to moving up and down.
See-saws are a great way for children to develop their coordination, balance and physical fitness. They are also a safe and fun way to learn about basic physics principles and the importance of teamwork and communication.
In conclusion, see-saws are an important component of any playground and can provide hours of entertainment and educational value for children. So next time you're at the park, grab a friend and take a ride on the see-saw!
2、跷跷板用英语怎么说怎么标注汉字
跷跷板是我们小时候很喜欢玩的游戏之一。它是由两个长木板组成的，它们通过一个中央支点连接在一起。两个人或更多的人可以站在木板的两端，通过重心转移和协调运动实现上下跳动。虽然这是一个非常受欢迎的游戏，但在不同的国家和文化里，它都有着不同的名称。
在英语中，跷跷板通常称为“see-saw”，这个单词在20世纪初出现在英国英语中，它的起源可能来自拉丁语“secare”（意思是“切割”）或“sedere”（意思是“坐”）。这个词在美国被广泛使用，并且在英国的一些地方仍然很流行。
在中国，跷跷板称为“秋千”，在汉字中通常写作“秋千”，其中“秋”表示秋天，而“千”则是指在秋天玩的游戏。据说，秋千的起源可以追溯到唐朝，有一种游戏叫做“鸟乘秋千”，即通过绳索和木板模拟飞鸟盘旋的场景，后来演变成了现在大家熟知的跷跷板游戏。
当然了，在不同的国家和地区，跷跷板的名称也会有所不同。在西班牙，它被称为“balancín”；在法国，它被称为“balan?oire”；在德国，它被称为“Wippe”；在俄罗斯，它被称为“качели”（“kacheli”）。
