After a few minutes' walk along this avenue, Langer returns to Yangda.

There is a seven-seater SUV parked under the 13 buildings of the staff dormitory of Yang University, which is Professor Lan Jinhui's car, and the second and third rows of seats are all removed, and the huge space vacated is used to carry goods.

The trunk of the car was opened, and two college students were busy working outside the car.

Ranger saw an astronomical device in the car, a 16-inch Dobson telescope.

In a secluded place away from the city lights, this telescope is the ultimate tool for stargazing. If your car can fit it, take it with you to explore the universe.

"Brother Tiger, what's the situation?, there's an event in the Star Club tonight?"

The SUV and the 16-inch Dobson telescope are all the property of Professor Lan, and Daddy's is Boy's.

Since the car and binoculars are Lan Jie's private property, can Lan Jie not ask about the situation?

Xiao Yihu closed the trunk and said, "Mr. Lan just sent instructions from the capital, and he asked us to shoot Leo, saying that it should be counted in the usual grades. ”

Lan Jie wondered: "Huh, the Star Club, a club that focuses on hobbies and loves, still counts the usual grades?"

Xiao Yihu explained: "Mr. Lan taught us atomic physics this semester, and I took a good picture of Leo, and I heard that the usual grades of atomic physics can get full marks. ”

Lan Jie was even more strange: "Brother Tiger, why are you so calm, what does Leo have to do with atomic physics? Don't you think Mr. Lan's logic is very confusing?"

Xiao Yihu said with a smile: "Teacher Lan is your father, and the person who knows him best should be you Ajie." ”

Lan Jie smiled bitterly: "Hehe." ”

"Considering all kinds of conditions, according to Mr. Lan's calculations, tonight is the best time to observe Leo in the Northern Hemisphere, and the opportunity must not be lost, even if Mr. Lan does not give this task, our members of the School of Physics of the Star Society will also go to Mazi Island for stargazing. ”

"Brother Hu, how many people, how many cars, and how many pieces of equipment are you going to stargazing on Mazi Island tonight?"

"Counting me and Ah Bao, as well as Mr. Lan's SUV and this Dobson, there are more than 20 people, 13 cars, and 13 pieces of equipment. ”

"Wow! I'm a Leo boy, and I really want to shoot a Leo!" Lan Jie rubbed his hands excitedly, his eyes burning with desire.

Leo is the most dazzling spring constellation, the only constellation in the spring sky whose shape matches its name. Lan Jie asked with anticipation: "Did Mr. Lan mention me in tonight's stargazing activity, and did Mr. Lan arrange for me to make some contributions to the Yangda Star Club?"

Xiao Yihu shook his head and said, "Sorry, no." Next time, Applejack, find a weekend time next time and see if there's a parking space for you. ”

"Oh, yes, I see. Brother Tiger and Brother Leopard, you should hurry up, it takes two minutes to drive from Yangda to Mazi Island, so far. Stay safe on the road and bye-bye. ”

Rangier returned home a little depressed, and after taking a shower, he did a few optical and celestial motion problems, and the Medal of Honor +1.

'The Star Club is a fart, children like to look at the stars, how can it be so cool to go all the way to the wild to see the stars and brush physics problems at home. Big brother physics, do you also support me to brush up on the questions at home?'

'Huh, big brother physics, do you think looking at the stars is also a kind of learning?

"But these guys from the Sheep Star Club drove my SUV and didn't take me into the car, what can I do?"

'Behave well and try to get on the bus next time?'

'Uh-huh, understood!'

Ranger was an optimistic young man who quickly pulled himself out of his depression.

"Applejack, it's time to take your pills. He Yuyi knocked lightly on the door of Lan Jie's room.

Lan Jie opened the door and asked, "What kind of medicine?"

"You slept on the couch all night, didn't you say you had a cold in the morning? ”

"Oh, I have a cold, so take your medicine. ”

Lan Jie took a cold medicine, it was still early, there was still half an hour before twelve o'clock, he watched TV with his mother in the living room and chatted for a while.

"Mom, have you rented out the house in the compound of the Sports Committee?"

"The rules of the sports committee are very strict, in case the tenant causes trouble in the sports committee compound, such as accidentally catching fire or something, the sports committee will definitely hold me responsible. ”

"Yes, yes, Mom, you are the leader after all, safety first, and the house in the compound of the Sports Committee is empty. The house in the sweet potato area is a commercial house, and the rules are not so strict, right?"

"The house in the sweet potato area is for your sister, and the monthly rent is in your sister's card. ”

Lan Jie was extremely shocked: "Give it to her?

He Yuyi said as a matter of course: "Your sister is an adult, she is very mature in all aspects, and can reasonably and properly handle various affairs inside and outside the campus. This time, your dad and I went on a business trip to the capital, and your sister arranged it very thoroughly, and your dad and I were very relieved of her. ”

"You're too partial to her. Lan Jie said sourly.

"Rest early, Applejack. He Yuyi yawned, and then went back to the master bedroom to sleep.

"The way of the world has changed ......"

The aggrieved Ranger goes to his sister's room to see his sister's certificates, medals, and dazzling experience.

With the eldest brother in physics, the second sister in mathematics, and the third brother in physical education, Lan Jie raised three fingers and swore a poisonous oath: "Lan Ying, I will definitely beat you, my experience will definitely be more dazzling than yours, and I will definitely take back the property that belongs to me with my own hands! If I can't do it, let me grow a hundred pounds of belly!"

Strike!

......

Sleeping, studying, exercising, socializing, high school life is simple and fulfilling.

On Wednesday morning, Lan Jie came to the second and third class classrooms, and he was curious to see if Teacher Wang would show up today.

Jingle bells.

Teacher Wang Liangcheng arrived at the second and third classes on time at 8 o'clock.

Lan Jie let out a long breath, and Mr. Wang, who had been missing for several days, finally returned to work.

At the same time, Lan Jie found that Zhang Yutong's seat was empty, and all her books were gone, leaving only a clean desk.

Lan Jie knew in his heart that Zhang Yutong had transferred to the international class, she was very efficient, and she would leave as soon as she said.

"Miss me, everyone?" Wang Liangcheng turned on the multimedia equipment, the white screen slowly unfolded, and the courseware was projected on the screen.

"Yes!"

"I've been coming to my hometown for the past few days. Wang Liangcheng briefly explained the reason why he took a few days off, and then moved on to teaching.

The first question is swiped out on the screen.

1. It is generally believed that the common ancestors of plants and animals are:

A. Bacteria;

B. Proto-green flagellates;

C, primitive mononuclear amoeba;

D. Cyanobacteria.

This is a typical biology exam question, which is a multiple-choice question, which mainly examines the students' understanding of a certain knowledge point.

The classmates laughed, B.

"It's not difficult to choose B, but the origin of life is not simple, and I will take a few minutes to talk about the important test points of the chapter on the origin of life. Wang Liangcheng's teaching habit is to pick up the topic first, and then talk about the knowledge points, he continued: "As we all know, the two main cornerstones of life matter are proteins and nucleic acids. Nucleic acids can only be synthesized under the action of proteins or proteases, and proteins can only be synthesized in the presence of their corresponding nucleotide sequences. So the question is, why did nucleic acids and proteins with such complex structures arise naturally and interact with each other in the early days of the earth?"

A classmate blurted out, "This is an engineer's experiment!"
