A clock face has several important parts. The 12 numbers around the edge mark the hours and minutes. The short thick hand is the hour hand, the long hand is the minute hand, and the thinnest hand is the second hand. Each hand moves at a different speed to show us the current time.
The hour hand is the short, thick hand on the clock. It tells us what hour it is. When the hour hand points directly at a number, that's the current hour. For example, when it points to 3, it's 3 o'clock. The hour hand moves very slowly and gradually moves between the numbers as time passes.
The minute hand is the long hand on the clock. It shows us the minutes. Each number on the clock represents 5 minutes. When the minute hand points to 12, it's 0 minutes. When it points to 3, it's 15 minutes. At 6, it's 30 minutes, and at 9, it's 45 minutes. We count by fives around the clock face.
Now we can read complete times by combining both hands. First, look at the hour hand to find the hour. Then look at the minute hand to find the minutes. Put them together to get the complete time. Remember that the hour hand moves gradually between numbers as the minutes pass.
欢迎学习如何看时钟!时钟是帮助我们知道时间的重要工具。每个时钟都有12个数字,从1到12排成圆形。时钟上有两根指针:短的蓝色指针叫时针,长的红色指针叫分针。
读取小时非常简单!首先找到短针,也就是时针。看看时针指向哪个数字,那就是现在的小时。在这个例子中,蓝色的时针指向数字3,所以现在是3点钟。
现在学习读取分钟。找到长针,也就是分针。分针指向的数字需要乘以5才是分钟数。比如:1表示5分钟,2表示10分钟,3表示15分钟。在这个例子中,红色分针指向6,所以是30分钟。
现在我们把小时和分钟组合起来读完整时间。首先看时针在哪里,然后看分针在哪里,最后把它们组合。这个时钟显示时针在3和4之间,分针指向6表示30分钟,所以完整时间是3点30分。注意时针会随着分钟慢慢移动!
现在来做一些练习题!记住我们学过的步骤:先找短针确定小时,再找长针确定分钟,最后组合成完整时间。分针的位置有一些常用的:指向12是0分钟,指向3是15分钟,指向6是30分钟,指向9是45分钟。试着自己读出每个时钟的时间,然后看看答案对不对!
