After 10 days of off-site training, the next step is today's off-site exam (road test). Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Except for Tian Suzhen, who did not participate in training for two days at home with her daughter, Niu Tiangou, Li Xiaomeng and other groups of students went out to train almost every day under the leadership of the coach.

The exam is conducted directly on the national highway.

The trainees sit in the cab, the instructor sits in the passenger seat, and in the back seat there is an instructor and a trainee preparing for the exam.

Niu Tiangou's first exam, due to his usual solid training, Niu Tiangou felt that the off-site exam was much simpler than the on-site exam, and the time was shorter.

Following the instructor's command, getting into the car, closing the door, adjusting the seat, fastening the seat belt, stepping on the clutch, igniting, hanging gear, turning signal, honking, releasing the handbrake and clutch -- Niu Tiangou quickly and neatly completed all the actions.

After a while, the examiner whispered, "Pull over." "Playing the right light, observing, slowing down, stepping on the brakes and clutch, turning back to the direction, hanging neutral, pulling the handbrake, and unbuckling the seat belt -- Niu Tiangou made a series of actions in one go.

"Okay, let's go down." The examiner quickly wrote the word "100" in the bottom column of the assessment form.

Passed so quickly? That's too easy, right?

Li Xiaomeng, Tian Suzhen and most of the students in the other groups also passed, a few students failed to pass, but they barely passed the make-up exam on the spot, and only one unlucky student still failed the make-up exam and had to wait for the re-exam next month.

Finally getting your driver's license!

Back at the school, the students who passed the test were very happy and discussed inviting their coaches to a meal.

Niu Tiangou, Li Xiaomeng, and Tian Suzhen discussed and decided to invite Coach Sun to get together to celebrate, after all, everyone is fate together, and there may be no chance to get together again from now on.

Coach Sun didn't have a false politeness, he readily agreed, and changed his usual seriousness and smiled.

The dinner was held in a restaurant.

Li Xiaomeng toasted Coach Sun and asked, "Coach Sun, how long do we usually wait to get a driver's license?" ”

"Hmm...... It's about a week at the earliest. ”

Coach Sun put down the wine glass, picked up the chopsticks and said: "Your students in this phase are considered to learn quickly, and they can successfully pass the test in the early two months, and they can get a driver's license. ”

"So can we drive on the road now?" Li Xiaomeng seems to be a little impatient, this thing has finally learned to drive, and he may not be able to help but want to show off his car skills in front of his girlfriend.

"Not yet. Although you have passed the test, but after all, you have not obtained a driver's license, if you drive on the road, it is still 'driving without a license', and you will be punished if you find out. ”

Coach Sun took a bite of food, put down his chopsticks and smiled: "It's better to wait until you get your driver's license before driving, anyway, you can't wait a few days." ”

"I've heard that there are two types of cars: manual transmission and automatic transmission, which one is better?" Niu Tiangou clinked glasses with Coach Sun and asked. He remembered that Manager Wang said that he learned to take a C license for a small car, a C1 photo for the manual transmission, and a C2 photo for the automatic transmission.

"This ...... The main difference between the two cars is whether there is a clutch pedal or not, the manual transmission has it, and the automatic transmission does not, and they have their own advantages and disadvantages. To put it simply, there are two words for manual transmission cars: 'difficult' and 'saving', and automatic transmission cars are also two words 'easy' and 'expensive'. ”

Seeing that everyone seemed to understand half-understood, Coach Sun thought about it and explained simply: "The manual transmission car has an additional clutch pedal, which is more complicated to operate, but it is fuel-efficient and economical, while the automatic transmission car has a clutch pedal, only the brake and throttle, and one foot operation is on the line, so the operation is very simple, it is a fool's car, but the structure is complex, the failure rate is high, the maintenance cost is high, and it is more fuel-intensive."

"So, there is no good or bad of these two cars, and what suits you is the best. I like to drive an automatic car, which is not only fuel-efficient, economical, but also fun to drive. ”

"Then I like to drive an automatic car, it's simple." Tian Suzhen seemed to deliberately sing against Coach Sun, venting the "sulking" she had suffered these days, standing up and toasting Coach Sun with a smile.

"Now that you've learned how to drive a car with a manual transmission, isn't it just like having fun with an automatic transmission?" Coach Sun didn't seem to care, smiled, and drank the wine in the cup.

The four of them chatted while eating, drinking, and then turned the topic to Li Xiaomeng.

"Uh, what locks do you make in your lock factory?" Niu Tiangou looked at Li Xiaomeng while eating the vegetables and asked. These days, in addition to being with Tian Suzhen, he is nervously practicing at school, and he doesn't have much spare time to chat with this product.

"That's a lot."

Seeing Niu Tiangou asking about locks, Li Xiaomeng put down his chopsticks, as if he was a treasure: "What door locks, drawer locks, furniture locks, cash box locks, luggage locks, chassis cabinet locks, safe locks, file cabinet locks, safe locks, mailbox locks, gift locks, stationery locks, toy locks, piggy bank locks, coin locks, power switch locks, elevator locks, telephone locks, computer locks, light box locks, vending machine locks, tax control machine locks, and what electric vehicle locks, car locks, train locks, heavy-duty padlocks, hinges, etc."

"In addition, our factory also produces all kinds of lock cylinders, including atomic lock cylinders, plum blossom lock cylinders, cross lock cylinders, various door lock cylinders, etc."

"I've heard that a lot of locks can be opened with a wire, is there such a thing?"

Hearing this, Coach Sun, whose face was full of wine, also seemed to be interested: "Those spy movies are all played like this, the agent put a wire into the door lock, and opened the door with a flick of the door." ”

"There is such a thing, but not one iron wire, but two, and these two 'iron wires' look like iron wires, but are actually not iron wires, but are special materials - metal steel wires that are easy to bend and not easy to break."

"Can you tell us about it?"

"You have to understand the principle of unlocking first." Seeing that Coach Sun was also interested in locks, Li Xiaomeng smiled: "Locks are composed of lock bodies, lock cylinders and bullets and other components, although all kinds of locks are different in structure, but the principle of unlocking is the same, except for some locks such as magnetic card locks and electronic locks."

"For example, ordinary door locks, door locks, cross-type door locks, etc., although their style, structure, and size are different, the principle of unlocking is exactly the same, and the reason why they are exactly the same is that their lock cylinders are round objects that can rotate freely.

"There are several small holes in the circular lock core that contain springs and marbles (in fact, they are cylinders), and there are also the same number of small holes of the same size in the position of the lock body corresponding to the small holes in the lock cylinder, and there are also marbles inside.

"When the lock is locked, these cylindrical pins are stuck between the lock body and the lock cylinder, so that the lock core cannot be turned casually, and it cannot be opened without a key.

"At this time, if you want to unlock the lock, you need to bend a small hook with a steel wire, commonly known as 'hook', stretch into the lock hole and push several bullets in the lock cylinder to the outside of the lock cylinder, so that the bullet does not jam the lock cylinder, and then use another end of the steel wire bent at right angles into a flat shape, commonly known as 'don't', insert into the lock hole 'don't' to hold the lock cylinder, and twist to make the lock cylinder rotate, after the lock core rotates, it will drive the mechanism in the lock body to open the lock.

"To put it figuratively, the role of the 'hook' is equivalent to the 'teeth' on the key, responsible for 'topping' the marble, and the role of the 'other son' is equivalent to the twisting of the key, responsible for driving the mechanism in the lock, and the two are equivalent to a 'master key' when combined."

"Oh......" Coach Sun nodded as if he had realized something.

Although everyone doesn't know much about locks, Li Xiaomeng's explanation does let everyone generally understand the basic principle of "'wire' unlocking".

Tian Suzhen smiled after hearing this, and quipped: "In this way, any lock is just an ornament for you, and you can be a 'Jiangyang thief'?" ”

"I don't dare, it's a crime, I don't want to go to prison." Li Xiaomeng's face was embarrassed, and he waved his hand again and again.

"Uh, if the safe doesn't have a key and a password, can you open it casually?" Niu Tiangou clinked glasses with everyone again, and suddenly remembered that when he went home last year, he went to the county seat Director Wu's house to open the safe, and couldn't help asking.

After everyone drank the wine in the glass, Li Xiaomeng frowned slightly and thought about it, and then said: "There are two types of safes: mechanical safes and electronic safes.

"The mechanical safe is a number lock, this kind of lock does not use a key, as long as you remember the number, and turn a series of numbers according to a certain operating procedure, the lock can be opened, so it is also called a 'combination lock' or 'number lock'.

"There are many kinds of this kind of number lock, some are simple and complex, the operation method is also different, and some also need key assistance. However, I can still open a mechanical safe like this without a password or key.

"As for the electronic safe, although it is a high-tech product that has only appeared in recent years, it is easier to open than a mechanical safe."

Seeing this confident look, Niu Tiangou didn't doubt it, smiled, and didn't ask anything more. It seems that I really have to learn from this kid in the future, "If you travel for three, you must have my teacher".

Unconsciously, the three of them drank up two bottles of liquor, and when Li Xiaomeng told the waiter to take the wine again, Coach Sun refused to drink it anymore anyway, Tian Suzhen only drank half a bottle of red wine, and then scrambled to pay the bill.

When she came out of the restaurant, Tian Suzhen's face was slightly pink, as if she had applied a faint layer of rouge, and the flowers were as delicate as flowers, Niu Tiangou also felt that her face was dry, Coach Sun's face was like a burning cloud, and Li Xiaomeng's face was like a burning monkey buttocks.

After the four broke up, Niu Tiangou returned to the bathing center, and suddenly received a text message from Tian Suzhen, saying that she was celebrating her birthday after a while, and she was only going to ask two good sisters to celebrate and celebrate, and wanted to invite Niu Tiangou to join in the fun.

Niu Tiangou didn't think about it, and immediately replied with three words: "I must come." ”

Nima, if it weren't for the presence of Coach Sun and Li Xiaomeng, looking at her smoky eyes, maybe she would have found a reason to ask him to come to her when she came out of the restaurant.
