The next day, Monday, was the national holiday of Columbus Day, and most Americans chose to go to the street to have a lively time, and Zhang Cheng and his aunt's family played at home.

Ye Zi bathed the little white tiger, and the aunt bought meat filling and vegetables yesterday, and today she began to prepare dumplings for lunch and evening after breakfast.

According to the previous tradition of my aunt's hometown, I had to eat dumplings during the New Year's Festival, I had to eat dumplings on cloudy days and rain, and I had to eat dumplings when I went far away. In short, you have to eat dumplings in a different way, don't you say it's delicious, but dumplings are delicious.

Although today's Columbus Day is only a festival of some ethnic groups in some countries in the Americas - it is definitely not a festival of the Indians, the former owners of the area, but it does not affect the eating of dumplings together as a family.

Zhang Cheng was lying on the sofa watching TV, and his cousin washed and wiped the sweat of the little white tiger and then put it in the yard and house to play. The cousin returned to the sofa, picked up Zhang Cheng's head, took a seat on the sofa, and put Zhang Cheng's head on her lap.

Zhang Cheng only felt a huge sense of happiness coming to his face, knee pillow, this is a knee pillow, and it is even more rare if it is a beautiful girl's knee pillow.

After watching TV like this for a while, Ye Zi felt that it was not interesting to fight and kill above, so he flipped his cousin's body one hundred and eighty degrees and let his cousin look at him.

Zhang Cheng reached under the leaf clothes and touched the belly of the leaf, it was not big, and he opened it to see that the white flowers were really beautiful. Then habitually along the flat little belly all the way up.

After a while, Ye Zi: "Cousin, I'm uncomfortable. He took off his pants as he spoke.

Zhang Cheng wanted to pick up the gun and get on the horse, but Ye Zi pressed his cousin's head between his legs, this was a few days ago when two people were in the room to watch a paid movie, Ye Zi didn't understand what movie men and women licked each other, so he asked his cousin to learn to serve his little sister with his tongue.

Then Ye Zi liked this activity, after all, if the cousin was a real little sister, it would inevitably be a little swollen and painful, and Ye Zi felt that he was not comfortable with his tongue.

The aunt came out of the kitchen with dumplings and saw this scene, and said to Zhang Cheng and Ye Zi: "Eat dumplings, what is delicious about fungus." ”

Ye Zi fought back: "Ah, this is abalone, ah, ah, big supplement." ”

Zhang Cheng: ......

It is normal for the mother and daughter to have disagreements, but when they were eating dumplings on the table, the aunt glared at the "brother-in-law": "Don't get used to this child." ”

Hey, it's definitely you who got used to your cousin first.

Now, let's eat dumplings first, the dumplings made by my aunt are also a must, eat the whole and bite it open, the delicious soup in the dumplings splashes around in the mouth, it feels like eating the peeing cow balls made by the star master on the god of food is too comfortable.

This is also the effect of eating freshly packed, no matter how delicious the dumplings are made by my aunt, the taste will decrease a lot after being frozen for a few days and then cooked.

When he went to school on Tuesday, Zhang Cheng still remembered the taste of dumplings.

However, this good mood was quickly shattered by the roll sent by the biology professor.

Zhang Cheng looked at the title of the paper, your sister can't understand it at all, Yishui's professional English is woody, this should be a topic for a master of biology. Lao Tzu is a freshman, and he has only been enrolled for more than a month.

Not only Zhang Cheng, but after reading the paper, more than 30 people in the whole classroom wailed, and Zhang Cheng wanted to copy and estimate that the only one who could make the correct answer in the entire classroom was the professor who came out of the paper in front.

The professor didn't bother to explain anything to everyone, in the professor's opinion, biology was originally standing at the highest end of life and looking down on all beings, and I didn't have a foundation and thought that if I didn't fit this industry, I would just leave and change my major as soon as possible.

The professor's idea is not wrong at all, don't look at the superpowers who have been engaged in manned spaceflight all these years, in fact, it can't be separated from the category of biology, astronauts don't talk about it, every time they go to spaceflight, they have to bring a large number of various plant seeds and experimental animals in outer space sterile and gravity-free, but there are various cosmic rays to mutate the seeds.

After these mutated space seeds are sent back to the earth, after being planted and selected from generation to generation, many of them have entered the dining table of ordinary people, and the offspring of these promoted plantings that have been selected after the mutation of space radiation either have higher yields or better taste, and can resist diseases and pests or something.

Since the super new seeds can be realized, how far is the next super new human - in fact, there is still a long way to say, according to the experiments of the hairy bear on the space station, female astronauts in space cannot conceive.

But this is also the charm of science and the moment when scientists come into play, if the male and female astronauts of the space station can get a big belly, what else do you need scientists to do.

It costs millions of dollars to develop a pen for writing in space, and hundreds of millions of dollars in scientific research funds for developing space conception instruments.

The test has a total of five questions and 30 minutes, everyone first looked at it with big eyes and small eyes for a few minutes, all of them were one action, shaking their heads, and then bowing their heads together to fill in the words on the paper, and now they can only start talking nonsense on the paper. Anyway, it won't, so I'll have to fill the rolls.

Thirty minutes later, everyone handed in the papers, and the professor received the papers, judged them in class, and then handed them out. It's just a simple quiz.

Universities in the United States rarely use a 100-point system, and some professors even only write satisfied and dissatisfied, passing and failing on the paper. But most of the time, ABCDE level 5 is still used, and when recording credits, an A is 4 points, B is 3 points, C is 2 points, D is 1 point, and E is 0 points.

This system is not absolute, and some schools still have an A+ score of 4.33. In other words, even if you smash it once or twice, it is possible to graduate with four points as long as you work hard. If you want to join a large company after graduation, you can't do it without such unnatural results.

Zhang Cheng quickly took back the roll, a bright red E, but he looked at the next DE nearby. This doesn't make people live, no, if you go on like this, you will drop out of school instead of graduate, Lao Tzu spent money to get a degree certificate, not a graduation certificate, looking at the white-haired and white-skinned professor with a big nose on the podium, Zhang Cheng thought to himself that this is a professor, you are forcing me.

Since you're forcing me, then I can only make a move. Thinking like this, Zhang Cheng took out the list of drug combinations that he had calculated a few days ago, reduced the amount, and then re-listed them all in English on A4 paper.

The professor sent all the papers back, and the class was almost over.

The professor got up and moved his arms twice and said, "This test is just a thorough understanding, I want you to know the general direction of the development of biology in the world now, of course, it must be a little more difficult for you who are new to the world. But I hope that in a year, two years, you will be able to give a satisfactory answer on this paper. This knowledge is also something that you will learn and master in the next year or two. ”

There was another wail in the classroom.

After class, the professor sorted it out and went back, Zhang Cheng followed from behind, and followed up with the professor's office: "Professor Nelson, I have a secret recipe here for you to see." ”

Professor Nelson took the prescription and looked at it for a while, and asked, "Biomedicine?" Did the witch doctor write it for you? ”

If you're not my professor, I'll kick you to death. This was left to me by my master. After the slander, Zhang Cheng said: "Professor Nelson, this is a secret recipe that has been secretly circulated in China for 2,000 years. ”
