At that time, it seemed that the teacher said so, why didn't I think of asking the teacher why?
Times have changed, and today's children are more able to think instead of just listening to teachers or other people.
Fortunately, when I grow up, I prefer to read books, and I have seen a few answers from other places. (Is it true that people without friends prefer to read books? Anyway, Chu Lihua is like this.)
"As for how the hair falls off? I now think that the other two reasons may be more important. One reason is that when living in the woods, there are leaves on the top of the head for shade, but it can't be done on the grassland, where the sun is basking every day. , it's not raining much yet.
Unfortunately, human beings are still creatures that are active during the day, and they have to run under the sun every day. If they are covered with hair, they will easily overheat. then what should we do? Hair removal! In this way, human hair becomes less.
Yifan, if you observe the kittens and puppies carefully, you will find that they will shed their hair when it is hot in summer. This is the same as when humans started to shed their hair when they lived on the grasslands when it was too hot. "
Chu Lihua tried to use examples that can be seen in life to illustrate.
"But when the weather is cold in winter, the fur of kittens and puppies will grow again? Then why doesn't human hair grow back in winter?"
"Because we need to wear clothes! If you have more hair, you don't need to wear clothes. Isn't that a lot less fun?"
Chu Lihua really didn't know this, so she had to fool around like this.
"Oh, by the way, Aunt Lihua, I just said that there are two reasons, what is the other one?"
None of them are easy to provoke, and Zhang Yifan has a good memory.
"There is another reason that you may not think of. It is lice. Have you ever seen lice? Probably not. Now that sanitary conditions are better, few people have lice. But in the past, lice were very common. They lived on people and sucked blood. Infectious diseases. Your mother must have seen it when she was a child. If you don¡¯t believe me, ask your mother.
What's more troublesome is that the lice will hide in the hair, so that you can't even hit them. But if the hair on the body is sparse, or even no hair, wouldn't the lice have nowhere to hide? Therefore, for humans in ancient times, less body hair means that they have fewer lice on their bodies and are less likely to be infected with diseases. In this way, these people will live longer and have more children. Over time, humans have less body hair.
In this way, hairless humans lived on the grasslands for two million years, and later humans became prosperous, not only living on the grasslands, but also coming to other places. Each of us today is a descendant of people who lived on the African grasslands millions of years ago. "
After Chu Lihua finished speaking, she closed her eyes and pretended to sleep. If this kid asks another question, he probably won't need to sleep tonight.
"Mom, what do lice look like?"
Seeing that Chu Lihua was asleep, Zhang Yifan turned to ask his mother again.
"Shh, Yifan, look, Aunt Lihua is already asleep. Let's not talk to wake her up, okay? Otherwise, she won't want to come to our house in the future. Do you still want Aunt Lihua to come and tell you stories! "
Tang Xue coaxed her son.
"Think about it, let's go to bed soon. But Mom, you must promise me that you will bring Aunt Lihua to our house often, okay?"
Zhang Yifan began to whisper the conditions.
After obtaining the consent of his mother Tang Xue, the little guy closed his eyes contentedly, and asked her mother to turn off the light.
Just like that, Chu Lihua fell asleep after a while, and she didn't have any problems with sleeping.
Unexpectedly, the next day Zhang Yifan caught a cold for some reason, and this little guy didn't take any injections or medicine, so he wanted to find Aunt Lihua.
Well, as Tang Xue's subordinate, there is no reason to refuse such a thing! Anyway, Chu Lihua felt that the cold apartment was far less warm than the apartment in this community.
And the most important thing is that Chu Lihua didn't want to go back and look at the empty room to see things and think about others.
Just like that, Chu Lihua stayed at Tang Xue's house for almost a week.
Clothes outside in winter are generally worn for a week before washing.
And inside, Tang Xue asked Chu Lihua to change and wash with hers.
In Tang Xue's house, it is a fully automatic washing machine, and the temperature in the room is very high, basically washing it at night and drying it the next day.
When Chu Lihua didn't go home for almost a week, she received a call from the landlord.
"Chu Lihua, what's going on, the rent has been paidTwo days in arrears? "
Ah, I forgot about this, when Zhang Guo was around, he would remind Chu Lihua to pay the rent.
"Are you going to transfer the money or come back and pay? I haven't seen you for several days."
The landlord continued talking after hearing that Chu Lihua was silent.
"What's wrong, Lihua?"
Seeing Chu Lihua holding the phone in a daze, Tang Xue asked.
"It's time for me to pay the rent."
Chu Lihua turned to Tang Xue and said.
"Okay, as long as you know, call me back later."
The landlord thought that Chu Lihua was talking to him, so he hung up the phone directly.
"What did the landlord say?"
"He hung up after he finished speaking."
"Otherwise, you don't need to pay it. The signal in your house is so bad that you can't be found at critical times."
Tang Xue called Chu Lihua several times and couldn't get through, and no one answered her WeChat.
Chu Lihua explained afterwards that the signal she lived in was not good. For this reason, Tang Xue had asked Chu Lihua to move several times.
"But I don't know where to move for a while! The houses here are all two-bedroom, and I have no one to share. And I can't afford that much rent."
Chu Lihua also wants to move a little bit. She doesn't have to wake up so early when she lives in Tang Xue's house these days, and she sleeps for a long time. She feels her energy is much better.
"Let me find a way for you. I remember that a colleague of our company lived in Wuwu College, not far from the subway and bus. It is also close to the company. The only disadvantage is that it is a bungalow. If you want to live, I will Ask her to ask you if there are any vacant houses."
Tang Xue's enthusiasm is not to mention.
"Yes! As long as the rent is not high, I don't choose a house, especially if the location is so good."
After hearing Tang Xue's description, Chu Lihua was a little moved. Where is Wuwu College? 818 off the high speed is simply not too close, okay?
Soon, Tang Xue began to help Zhang Luo.
Tang Xue's former colleague asked after returning from get off work. A family just happened to move out on Saturday, and Chu Lihua could move out on Sunday.
After confirming it, Chu Lihua called the landlord and said that she would go home for vacation soon, so she would not rent it.
The landlord asked Chu Lihua to pay a liquidated damages of 50 yuan per day, otherwise the deposit would not be refunded or another month's rent would be paid. (Remember the site URL: www.hlnovel.com
