That is, the difference

That is, the difference between the two pictures, that is, the two pictures on the right of the word, and the second picture on the right and the fourth picture on the right. In this way, the two pictures can be distinguished.

The source of these two words is very interesting.

Oracle's "that" is the same as the "that" is "on the left, all of which are like a fool;
"That is," the right part is like a person sitting on the left. It seems that the food is approaching and will have a delicious meal. The original meaning is "I will eat ";
While the right part of "both" is like a person sitting down with a mirror. His mouth opened to show that I was full, and his righteousness was "exhausted ".

It is no wonder that the dictionary explains that "that" means "proximity," that is, "already. Here we can better understand and distinguish the two words. You can tell these to students (better by Oracle), and then say, "Go, close," is "that"; "Leave, already" is "yes ".
