For example: [Let for any smooth directed closed surface s, there is xf(y)dydz+yf(x)dzdx-z[b+f(x+y)]dxdy=0, where the function f(x) is continuous in (-,+), and f(1)=a(a,b are constants), find f(2010).]

Then the next question: [Xiao Ming and his friends went to dinner, came to a small restaurant, the waiter counted the number of people, brought three pairs of dishes and chopsticks, Xiao Ming said that she took too much, the waiter looked at it and said, "I'm sorry to read it wrong." The next action of the waiter made Xiao Ming break out in a cold sweat. What did the waiter do? 】

Su Man turned a few pages down, up to astronomy and geography, down to demons and monsters, as far as the Milky Way galaxy, and as close as to the celebrity divorce to Bo Gongtang, a full 100 pages of A4 paper, everything.

She opened her consciousness to observe the madness of everyone's answers, and couldn't help laughing.

"Su Man! Answer the question, laugh at what you laugh at! Lu Chengfeng said that such a picky thorn is very flat in a bowl of water.

Su Man raised his hand and signaled: "Report!" There is a question here that is not suitable for me to answer. ”

Everyone looked up at Su Man, who was sitting on the same pony as them.

Lu Chengfeng's eyes narrowed half-narrowed, and asked, "Which one?" ”

"Question 111, do you have a girlfriend? I'm a woman, you're encouraging me to do social ......"

Before Su Man's words were finished, Lu Chengfeng felt that the thunder thousands of miles away seemed to have launched a guide (Dan), which directly bombarded him to the Hades Palace, and hurriedly replied: "Do you change it to do you have a boyfriend?" ”

"Oh." Su Man couldn't help but smile, turned back to the first page and began to answer the question.

Lu Chengfeng looked at Su Man as if he hadn't answered the question just now, and he was panicked.

After hesitating for a long time, he walked up to Su Man, picked up Su Man's test paper without saying a word, and then turned to the page with 111 questions, crossed out the sentence that had not been changed, and wrote by hand: [Do you have Captain Huo Yanting in your heart? 】

After doing these actions, Lu Chengfeng turned around and left with a sigh of relief.

Su Man looked at the changed title and couldn't laugh or cry.

The sky is getting darker, and the dim street lights are on, but they can't bring a trace of warmth.

The sky was sprinkled with goose feathers and heavy snow.

The selection fighters, who had been sitting on the pony for an afternoon, were all so cold that their noses were red, and their hands and feet were so stiff that they couldn't move.

At this time, Su Man stood up and stretched hard: "Report!" The written test has been answered. ”

Everyone without exception all looked at Su Man, and their surprised expressions were beyond words.

Lu Chengfeng, Fire Wolf and others walked up and flipped through the test papers in Su Man's hand, from the initial expectation to the later praise.

They thought that Su Man would answer very well, but at this moment, it can no longer be described as a good answer!

Since they looked it up, they haven't seen any mistakes.

Lu Chengfeng hurriedly turned the test paper to question 111 again, only to see a line written on it: [For your desire to survive, you must have. 】

Lu Chengfeng grinned, and he could see the back molars with a smile.

"Excuse me, what am I going to do next?" Su Man asked disappreciatively.

Lu Chengfeng pointed to a dormitory building not far away: "Rest." Raise your spirits and take the second assessment tomorrow. ”

"Yes." Su Man put away the little horse and walked forward, trying to get his backpack by the way.

At this time, the crow stopped her: "I'm sorry, from the moment I started answering the question, I can't touch my backpack again." ”
