Chapter 938 (1/2)

Ye Ling ate this meal very heartily. I don't know if the father and son took care of her for the sake of gentlemen. In this empty and low moment, she saw the warmth of human nature. In private, she was very moved.

Together sang a birthday song, ate cake, Ye Ling initiative way: ”the biggest birthday star, today I am responsible for washing dishes!”

After all, Ye Ling always feels that he should do something.

As soon as she took the chopsticks, Qiao Yichen seized them and said, ”why do you let the guests do it? An aunt will come to wash it tomorrow! ”

At this time, Qiao an also stood up: ”teacher ye, let's do our homework!”

During the conversation, she was dragged into one side of the study, and obediently spread out all her homework, which was totally different from the previous attitude of pushing three blocks four.

Seeing that he has changed, Ye Ling is very happy. He takes out the notes for preparing lessons, and then explains a chemical equation to him in a very simple way: ”chemistry is actually a very interesting knowledge, which is about the neutralization reaction of acid and alkali. In fact, it is easy to remember that acid (H) + and alkali (OH -) exchange components to generate salt Reaction with water. Have you ever eaten sour steamed bread? ”

Induced, ye Lingdao:

”there used to be a little girl who liked to sit and watch her mother steam steamed bread when she had nothing to do. Then she found that occasionally when the steamed bread was about to mature, it would smell sour. At that time, when she was poor, she was afraid of starvation. However, every time the pot is opened, the steamed bread is fragrant. Later, she knew that before the pot was opened, as long as the sour taste came out, her mother would certainly mix some water to spray on it. Then she remembered that when she grew up, she opened a steamed bread shop and made it very successful! This is the wonder of chemistry. The lactic acid of poor fermentation of steamed bread will have sour taste. The water sprayed is alkaline water. If two are neutralized, there will be no sour taste naturally! It's amazing, it's easy to remember, isn't it? As long as you remember the two main substances (H +) and (OH -), and then put them forward, it's easy to answer! Do you understand? ”

The most annoying and boring lesson was told so interesting by her. Joan was obviously very interested in it. He picked out several of the equations and quickly wrote out the answer:

”teacher, these are all of this type. Do you think I did it right?”

”Ann is so smart! Very talented! Yes! And here, you should pay attention to the mark, as long as careful, right, right, right! Moreover, if you learn chemistry well, you can do a lot of things you want skillfully and make your life beautiful

She gave him some advice, and Ye Ling seemed to have changed her personality. However, she didn't know that her unintentional praise was actually the biggest reason for Joan's change.

Criticism and denial have never been a good way of education, and the earnest and induced change of internal causes is the essence of the lesson.

At the door, looking at this scene, the middle-aged man with the fruit tray quietly retreated out.

Just accompanied Joan to make half of the paper, but saw him suddenly put down the pen.

”What's the matter? Is there a bottleneck? ”

”Mr. Ye, are you tired, too? , you go out to eat some fruit, have a rest, and take a walk downstairs with my father! He's at home, I can't do it well. Please ~ half an hour, I'll finish this paper! ”

The big boy looks adored and begged. Ye Ling looks at him and stands up: ”OK! But you can't cheat! ”

Later, she lowered her voice and said, ”otherwise, I'll tell your father that the next allowance -”

made a ”OK” gesture, and Joan smiled with a fist.

Generally speaking, Joe's father seldom goes in and out of the door, occasionally passing by and chatting with each other for one or two sentences. After a simple communication, they really go out together.

He went downstairs and walked in the community. Ye Lingdao:
