Since then, Zhang Chenhao has been eating with Li Tianran in the canteen from time to time, and he will bring breakfast milk to Li Tianran every morning.

The two chatted specially, and their favorite food is similar, they both like to read books, like basketball, like to watch street dance, and like games, which should also be the reason why many of Li Tianran's preferences are a bit boyish.

Since he was a child, Li Tianran has liked knife and gun, four-wheel drive car, yo-yo toys, and boy games such as treasure shooting stickers, but he has no interest in Barbie dolls, makeup, and house games.

Slowly, the relationship between the two is getting better and better, and Li Tianran also feels very happy to be friends with him.

At lunch time in the cafeteria, "Xiao Ran, I'm looking for you to eat together, the classmates are all coaxing on the side, will you feel uncomfortable, I'll go to them and tell them to stop coaxing" Zhang Chenhao asked Li Tianran thoughtfully while eating.

"It's okay, I won't be unhappy, we've been together for a long time, everyone will naturally get used to it, and we won't keep coaxing.

But it's okay to talk about it, after all, it's a big trouble, and it's not good to attract the attention of the teacher......" Li Tianran took a sip of sour yogurt and replied.

"We've been together for a long time?" Zhang Chenhao's clever moment grasped the key point of Li Tianran's words, and immediately smiled, looked at Li Tianran and confessed sincerely, "Xiao Ran, I like you, are you willing to be my girlfriend instead of just a good friend?" ”

"Hmm" Li Tianran nodded, looked at Zhang Chenhao, the corners of his mouth raised slightly, he also likes Zhang Chenhao, why refuse, why not enjoy the present, don't care about whether the future can last for a long time, and only leave a good memory of youth for the current self.

When Zhang Chenhao saw that Li Tianran agreed, he immediately became a chatter with joy and started the gushing mode......

Li Tianran listened with a smile and felt that what Zhang Chenhao said was very interesting......

At night, because of the reason that his roommate forgot to close the window after opening the window during the day, several mosquitoes entered the dormitory.

In the morning, after Li Tianran finished applying wind oil essence, he couldn't help but send a text message to Zhang Chenhao, complaining fiercely about the hatefulness of mosquitoes......

Zhang Chenhao also sent a message back to scold the stinky mosquitoes, and told Li Tianran to remember to check whether the dormitory screen window was closed properly when the dormitory was ventilated in the future, and also told Li Tianran how to put a basin of soapy water in the house to repel mosquitoes.

Zhang Chenhao's family conditions are quite good, his mother is a civil servant, and his father is an executive of a company.

Both of them have mobile phones, and they have to text each other every night to say good morning, and they have to say good night before going to bed, and they have to send dozens of text messages every day, contributing a lot of phone bills to the mobile company.

Li Tianran is very strange why mosquitoes come out in summer, and autumn mosquitoes are so poisonous, so where do mosquitoes go in winter?

Li Tianran is the kind of person who will immediately look for answers when he has questions, and immediately checked on the Internet, and it turns out that mosquitoes begin to appear in April every year and reach their peak activity in mid-to-late August.

In autumn, when the climate gets cold and the temperature drops below 10°C, mosquitoes will stop breeding and die in large numbers, and very few mosquitoes will survive, and they will hide in places where they can take shelter from the wind and cold, such as in the cracks of walls, such as in warmer and more hidden places indoors, such as behind wardrobes.

This can not only avoid the harsh winter, but also reduce the rate of metabolism and avoid starvation to death, a bit like hibernation.

Outdoors, mosquitoes tend to hide in warmer places such as inside heating pipes, and the eggs that appear in the second year are more likely to hatch.

It turns out that in addition to bears, turtles, hedgehogs, snakes, and frogs, mosquitoes also hibernate.

At breakfast, Li Tianran shared with his boyfriend that he had just learned that mosquitoes were also hibernating, Zhang Chenhao said that summer is his favorite season, and the only thing he doesn't like is mosquitoes, if only mosquitoes become extinct......

Li Tianran also thinks so, and has specifically investigated, some people believe that the general principles of ecology tell us that removing a species from the ecosystem often leads to a chain reaction.

But in reality, the web of life is not so fragile, and when you cut off the mosquito, the web of life will not fall apart.

The real reason for not exterminating mosquitoes is actually that humans have tried various methods and have not been able to exterminate mosquitoes.

In fact, countries around the world spend tens of billions of dollars every year to get rid of mosquitoes.

Brazil spends more than $1 billion a year on mosquito control; In 2014, dengue fever came out in Guangzhou, so the Guangzhou government issued a government procurement of 200 million yuan to control mosquitoes.

Foreign media have reported that in order to stop the spread of malaria and other infectious diseases, the British biotechnology company Oxitec has bred a genetic mutant mosquito to be released in Florida and Texas in the United States in the summer.

But in fact, everyone underestimates mosquitoes, take the white line mosquito as an example, its eggs, can live for 6 months without water, each female mosquito produces a total of about 1000-3000 eggs, the water source, the temperature is right, just a few weeks, they will develop into adult mosquitoes that can reproduce offspring.

So, it's not that we don't exterminate mosquitoes, it's that the concubines can't do it!

Therefore, Li Tianran could only helplessly tell the squad leader's boyfriend that the current scientific and technological mosquitoes cannot be extinct, and all we can do is prevent mosquitoes......
