Extraterrestrial parasite

On January 2, 2015, at 10:11 a.m., in an open classroom of a well-known university in Hangzhou, Yuan Chengyan's eyes were dazed, and he was spinning the ballpoint pen in his hand boredly, waiting for class time to arrive.

He was in a very unhappy mood. Yesterday, his old man Yuan Zhengming called him again and asked him not to spend money arbitrarily. How could Yuan Chengyan feel comfortable when he was already in college and still took care of everything.

"The old man's drunkard..."

With a grunt, Yuan Chengyan's back trembled, and he almost threw away the ballpoint pen spinning in his hand.

"Lao Yuan, what are you doing?"

His friend Fu Chuan had a wicked smile on his face and was not polite at all. He sat down next to him and asked, "Are you peeking at beautiful women again? Well, where are you? Where are you?"

Fu Chuan pretended to look around, causing Yuan Chengyan to roll his eyes.

"Why don't you go play with yours? Do you still have time to come to class?"

Yuan Chengyan said unhappily.

"Tch, it's not like you don't know whose class it is, how dare I not come?"

For "Old Ghost Wu" who must be called by name in every class, most students hate him with gnashing of teeth. People who like to skip class and sleep in, of course hate this very much. Students who don't skip classes also hate his high demands on exams.

All in all, only a small number of students who like Wu Laogui's class are interested in literature www.cfwx.net. This is because he is more interesting and serious in teaching. Otherwise, I am afraid no one will like a teacher who does not show any affection in the exam. .

"Of course, there is a mobile version, so you can still play it in the classroom."

Taking out his Huawei mobile phone, Fu Chuan was very proud and clicked on the open game icon to enter the game through the mobile phone interface.

"You are playing with your mobile phone in class. Aren't you afraid of being discovered by Old Ghost Wu?"

Yuan Chengyan couldn't help but say.

"Isn't this just going to depend on your reminder later? Brother, everything depends on you. I'll treat you to a big dinner at noon today."

Patting Yuan Chengyan on the shoulder, Fu Chuan looked serious.

Yuan Chengyan smiled bitterly, the so-called feast was nothing more than food in the cafeteria. Talking about a big meal was naturally just a joke between them.

Shaking his head, Yuan Chengyan persuaded: "The exam is coming soon. If you continue to play like this, be careful that you can't pass the questions asked by Mr. Wu."

"It's okay. We still have a few days to go. There will be a road to the mountain. Don't be afraid."

Even though Fu Chuan knew that the final exam was coming soon, he was not worried at all. There would always be a solution by then.

"well……"

Persuasion is ineffective. Yuan Chengyan, who knew his friend's temper, immediately gave up trying to persuade him. Although Wu Laogui was funny in class, he was selfless and sharp-eyed during the exam. It was extremely difficult to get through the difficulties by cheating. Now he can only silently wish his friend in advance.

"Jingle Bell……"

The class bell finally rang, and the students who were sitting in the classroom chatting immediately sat back in their chosen seats. Closed his mouth.

Not long after, a man in his thirties appeared. He walked in with a folder, came to the desk and smiled slightly: "Good morning, classmates."

"Teacher is also good."

From the sparse answers below, it was obvious that many students simply ignored his greetings. Fortunately, Wu Zhongling, the "Old Ghost Wu" whom Yuan Chengyan and the others called, was not angry either and spread out the folder. Insert the USB flash drive so that the projector can display its own teaching materials on the screen.

"Students, the exam will be held in a few days. I know that everyone is very happy because this winter vacation will be longer than ever... Well. But students, don't get too happy too early. I will invigilate the exam this time. And there will never be any favoritism... As for begging and treating guests after the exam, don't think too much about it."

Wu Zhongling was speaking with a smile on his face, but the content of his words was so cruel that the faces of everyone below turned pale.

This devil!

At the same moment, everyone below collectively cursed in their hearts.

"Well, because the exam is about to take place, and the content of this semester is basically the same, I won't explain much in this class. I will just tell you some interesting things related to our subject."

As soon as these words came out, hundreds of people below couldn't help but become curious, what is this interesting thing?

"Pa bang bang..."

Wu Zhongling walked back and forth on his leather shoes and asked with a smile: "Now I ask a question. Can anyone answer it immediately? Everyone knows that penicillin was created by the Englishman Fleming. So who was the first Chinese to create penicillin?" ?”

This question is not difficult. Those who are interested will certainly remember to learn it. Someone immediately answered: "It was created by Zhu Jiming in 1943 by separating Penicillium from leather."

"Yeah, that's a good answer."

After applauding, Wu Zhongling smiled and asked the person who answered: "Where is Zhu Jiming from?"

"Well……"

The man was stunned and speechless. Not only him, but the others were also in a daze. Who would be so bored as to remember the hometown of an unimportant person?

Isn't Old Ghost Wu playing a trick on them?

"Haha, just kidding, don't mind."

Wu Zhongling waved his hand and asked the man to sit down, "Mr. Zhu Jiming is an amazing person. Not only was he the first scientist in China to develop penicillin, he also successfully developed a highly attenuated live measles vaccine. But he has made a huge contribution to China's virology research entering the era of molecular biology. If your future results can be one-tenth of his, you will be able to brag for a lifetime."

After sighing, Wu Zhongling said interesting things, and of course he would not break his promise. It's just that the interesting things he said were not the interesting things that everyone imagined, but the life stories of famous scientists in the biological world. There are many positive energies that inspire people to move forward, and there are many. A story that makes people laugh out loud.

If nothing else, it at least gives everyone a "new look" at the seriousness of the older generation of scientists, and makes people feel that life among the older generation is quite interesting.

After telling the interesting story, Wu Zhongling suddenly asked: "A simple question for everyone. Who can recite all the antibiotics word for word now? Well, how many can be recited? Let's see who can recite more at once. Who dares to recite it? A challenge?"

Naturally, it is impossible to memorize all the thousands of antibiotics. I can’t remember, but Wu Zhongling’s request was to see who could memorize more, so after a while of pushing and shoving, some students were more courageous and stood up and opened their mouths to memorize: “First-class antibacterial drugs include cephalexin, cefotiam, Cefadroxil, cefoxitin, cefazolin, cefradine, cefaclor, cefuroxime..."

Jili Gulu carried it for a while, getting closer to the back. The student wanted to think about it for a long time.

He was quite smart, and he memorized the common antibiotics from the first level, and then started from the classification in detail, thus avoiding the phenomenon of memorizing the antibiotics in the past and repeating them later. Of course, this is also the basic common sense for learning antibiotic drugs.

"..."

After spitting out the last name, the more courageous student hesitated for a long time and couldn't recite it.

"Okay, classmate, please sit down. It's really good. I memorized one hundred and twenty-seven. I can barely pass."

Everyone was surprised. Was this old ghost Wu still counting silently?

If he hadn't counted silently, who would have known how many of them the man who had been chirping for a long time had carried?

"Students, studying medicine sometimes requires not only a certain amount of talent, but also hard work to memorize. Memorize it. If you can't even pass the basic memorization level, how can you learn the following content? The amount of memorization in medicine is not Big, as long as you put more thought into it, you can easily remember the things you need to remember..."

Everyone below was sweating when they heard this. Yuan Chengyan couldn't help but wipe the sweat from his forehead. It was not easy to be frightened into a cold sweat by Old Ghost Wu in winter.

After using some simple words to frighten the students below, they became stiff. Wu Zhongling slowly picked up the cup and took a sip of water, and said: "A little question for everyone, what is the treatment for MRSA (methicillin-resistant Staphylococcus aureus, for which beta-lactam antibiotics are no longer effective)? "

This small question naturally does not trouble many students. The chorus responded: "Vancomycin."

"very good."

Wu Zhongling nodded and said again: "So what is the treatment for VRE (vancomycin-resistant enterococci)?"

This is also very simple and will not be difficult for most students.

“Linezolid,” many people replied in unison again.

"Very good, very good, good answer."

Having said this, Wu Zhongling's "kind" face suddenly showed a strange smile: "Then what if it is also resistant to linezolid?"

Everyone who was about to answer in unison opened their mouths and suddenly swallowed the words that rushed to their lips. The classroom suddenly fell into a deathly silence.

No one answered. Hundreds of people in the classroom looked at Wu Zhongling in silence.

In fact, this question is also very simple. The reason why no one has answered it is that the answer is too simple. It is even simpler than the first two questions. It is so simple that no one has answered it.

Because this is the end, there is no way forward, no medicine is available!

Wu Zhongling still kept a smile on his face, but the smile on his face at this time, in the eyes of most people, had a cruel sneer.

"Jingle Bell……"

"Okay, don't be too afraid. There will be a road before the car reaches the mountain. You must learn from ordinary people and live happily. Otherwise, before the patients are scared to death, you doctors will be scared to death first. Isn't this ridiculous and generous? ?”

Wu Zhongling's smile gradually faded and became colder: "Although what I say may not be of much use, since you have chosen this path, sometimes you have to overcome your inner fears first. The war between humans and diseases has been going on since ancient times. It has never stopped, and it will not end in the future. If we lag behind the advancement of the disease, it may not be a good thing for the entire human race. In the near future, the older generation will pass away, and the future will definitely belong to you. These young people, I hope you can truly take on this responsibility by then. Okay, get out of class is over."

As soon as get out of class was over, everyone breathed a sigh of relief and laughed and shook off their worries. A few people took Wu Laogui's words to heart. Only Yuan Chengyan's eyes were shining, and he didn't know what he was thinking.

Time continued to pass and the earth continued to rotate. Just after Andres appeared in front of the world, a crisis began to brew in South Korea, not far from China.
