求翻译：一个平衡的杠杆上，一些人在左，我们的地球在右；第二张图上左边新增的人使杠杆不再平衡。之后问学生：看了这两幅图，你会想到什么？又是什么引发了这个问题？学生会表达一些自己的见解，这时不论他们的见解是否正确都要给与鼓励和表扬，然后问学生：是否知道每一天每小时每分钟每秒钟全世界会新增加多少人口？学生会很有探究答案的欲望，这时很自然地让学生打开书去阅读50课的文章STANGDING ROOM ONLY 并找出我给出的这张表格的答案。是什么意思？

A balancing lever, some on the left and our Earth in the lower right; person released on the second picture on the left lever no longer balance. Asked after the students: look at these two pictures, what do you think? What caused this problem? Students express their views, regardless of their opinion is correct is to give encouragement and praise, and ask the students: aware that every day will be added every hour every minute, every second the world population? The desire of the probe into the Student Union is the answer, then it is natural to let students open the book to read the article STANGDING 50 courses given by the ROOM ONLY to find my answer to this form.
