Who has some IQ questions about teachers or Teacher s Day????

It's me upstairs, it's the wrong number, add the points to this number, and attach the answer, thank you.

Xiao Ming and Xiao Qiang are both students of Mr. Zhang, Mr. Zhang's birthday is the n day of the month m, both of them know that Mr. Zhang's birthday is one of the following 10 groups, Mr. Zhang told Xiao Ming the m value, and told Xiao Qiang the n value, and Mr. Zhang asked them if they knew what day his birthday was?

March 4, March 5, March 8.

June 4 June 7.

September 1 September 5.

December 1, December 2, December 8.

Xiao Ming said: If I don't know, Xiao Qiang definitely doesn't know.

Xiaoqiang said: I didn't know it at first, but now I know.

Xiao Ming said: Oh, then I know too.

Please deduce what Mr. Zhang's birthday is based on the above dialogue.

The answer should be September 1.

1) First of all, analyze these 10 sets of dates, and it is not difficult to find that there are only two sets of dates, June 7 and December 2.

The number of days is unique. From this, it can be seen that if Xiaoqiang knows that n is 7 or 2, then he must know the teacher.

Birthday. 2) Re-analyze "Xiao Ming said: If I don't know, Xiao Qiang definitely doesn't know", and the 10 sets of dates.

The number of months is 3,6,9,12,And there are more than two sets of dates in the corresponding month,So Xiao Ming learned about m。

It's impossible to know the teacher's birthday.

3) Further analysis of "Xiao Ming said: If I don't know, Xiao Qiang definitely doesn't know", combined with step 2.

Conclusion, it can be seen that Xiaoqiang will never know after learning n.

4) Combining steps 3 and 1, it can be inferred that all the dates of June and December are not the teacher's birthday, because.

If Xiao Ming knows that m is 6, and if Xiao Qiang's n==7, then Xiao Qiang knows the teacher's birthday. (Section.)

Step 1 has been launched), in the same way, if Xiao Ming's m==12, if Xiao Qiang's n==2, then Xiao Qiang can also know the teacher's birthday. That is: m is not equal to 6 and 9. Now all that remains is "March 4th, March 5th, March 8th, September 1st."

September 5 "five sets of dates. And Xiaoqiang knows, so n is not equal to 5 (there are March 5 and September 5), at this time, Xiaoqiang's n (1,4,8) Note: Although there are three possibilities for n at this time, for Xiaoqiang, as long as you know one of them.

One, to draw conclusions. Therefore, there is "Xiaoqiang said: I didn't know it originally, but now I know", and we still need to continue reasoning.

At this point, the rest may be "March 4th, March 8th, September 1st".

5) Analyze "Xiao Ming said: Oh, then I also know", indicating m==9, n==1, (n==5 has been excluded, there are two groups in March).

Xiao Ming and Xiao Qiang are both students of Mr. Zhang, Mr. Zhang's birthday is the n day of the m month, and both of them know that Mr. Zhang's birthday is one of the following 10 groups, Mr. Zhang told Xiao Ming the m value and the n value to Xiao Qiang, and Mr. Zhang asked them if they knew what day his birthday was?

March 4, March 5, March 8.

June 4 June 7.

September 1 September 5.

December 1, December 2, December 8.

Xiao Ming said: If I didn't know, Xiao Qiang definitely didn't know Xiao Qiang said: I didn't know either, but now I know.

Xiao Ming said: Oh, then I know too.

Please deduce what Mr. Zhang's birthday is based on the above dialogue.

Why!

Are you sure there's an answer to this?

On this issue, civilization has also been looking for it.

Teacher's Day Essay.

Some people say that the teacher is the brightest Big Dipper in the sky, pointing us in the way forward; Some people say that the teacher is the coolest mountain spring in the mountains, watering us little saplings with fragrant nectar juice; Some people say that the teacher is a lush leaf, with his powerful body and the flowers and bones that protect us in the future.

Teacher, I worship you, I can't say why I have this kind of admiration, looking at the neat and beautiful handwriting you left on the blackboard, but I can't measure how much mystery and hard sweat is hidden in it, I only know that this is your selfless dedication to the cause of social education. Listen to every word you say on the podium, what kind of sound is that? Is it nature's clear birdsong?

Is it the harmonious melodic sound of a classical instrument? No, it's not, it's a kind of sound from outside the world, containing the beautiful tones of the world, and it sounds deep to us, because that sound is not an ordinary sound, but a signal sound of knowledge, and when you hear this sound, you know that there is a lot of knowledge that is going to come from afar and enter the station of your wisdom brain.

Teacher, you are the brightest Big Dipper in the sky, and I am a black duck who is lost in the red dust, whenever I lose my way, as long as I see your dazzling light, I can find my way home. I still remember when you first picked me up, when you changed me from a child full of innocence to a primary school student with ideals and achievements, how much you paid for us, we are enjoying our own success and enjoying our own happiness, but we can't forget the teacher, you are the coolest mountain spring in the mountains, you use your erudition to let us understand this vast and boundless world, let us see the world is big, you are like our telescope, let us see farther, see more clearly, just like mountain spring water, Clear enough to let you see underneath. Teacher, you taught us to have the courage to fight against difficulties, not to be overwhelmed by difficulties, I still remember what you often said, "If you don't experience wind and rain, how can you see a rainbow, no one succeeds casually."

Yes, success and difficulties are relative, and if there are no difficulties, how can we talk about success?

Teacher, you are a lush leaf, you use your strong body and protect our future flowers. You are never very stubborn for you, you always silently dedicate your body, for your students, for your mission, you are willing to be a green leaf rather than a red flower, you want to use your own ability to polish the dawn of this world, so that the dreams of students fly higher and farther.

Teacher, you have used your life to teach us why we should have pursuits, why we should have ideals, and why we should surpass ourselves. Teacher, you leave the most beautiful smile to this wonderful world, you are the most beautiful myth in our hearts.

Standing under the bright red flag, we ushered in an unforgettable Teacher's Day, in this happy, warm and exciting moment, on behalf of the students of the whole school, I hold out our most innocent, sincere and warm heart, I wish all the teachers of the first middle school who care about and love our growth a happy holiday, happiness and health! We even hope that our greetings and blessings will smooth out the wrinkles on the gardeners' faces, wipe off the slight frost on the gardeners' temples, and let the gardeners' wise eyes shine forever!

Being a teacher is hard work, but the work of shaping the soul is great; The burning of the red candle is short-lived, but it burns herself and illuminates the hearts of others for eternity. The reason why you are great is not only because you impart our scientific and cultural knowledge, but also because you set an example for us to be human beings.

Thank you, Teacher, for making us confident and able to surpass ourselves. You have proved to us that learning is not a burden, but a joy and responsibility, a key to the world we never knew.

You have taught us to explore boldly with our minds and hands, to seek and discover, and to make life full of surprises!

Thank you, Teacher, for being a person we can always trust to ask for help when we are in trouble in life. You let us know that we can confide everything in you if we want to. You often say that you were a child, so you can understand your child's joys and sorrows.

Thank you, Teacher, for making me understand that we can learn from failures, gather strength in difficulties, and find light in the darkness. You give us the courage to use our brains, and at the same time you ask us to be open-minded.

You put beauty in our hearts, giving us teachings, insights and imaginations that shape our lives. No matter what we build, you always help us lay the foundation, and you do your best for us to grow! Perhaps every detail of your lecture will be forgotten by us over time, but your passion, courage and love will always remain.

Thank you for never being cynical about us, always paying attention to us when we try, and always letting us know that you have seen our results, even if the results are so insignificant. You are the one who has taught us that life can be as thin as a piece of paper, as deep as the sea, as vast as the sky, and that we have to make our own choices. Every question, every discovery, experience you have led us through has fascinated us and allowed us to see the sparkle of wisdom in the ocean of knowledge.

Suddenly, one day we find that you are old, tired, and tired. You don't need the understanding, comfort, and support of others, and yet you are so silent, quiet, resolute, and awe-inspiring.

O red candle, your flickering candle flame is as fluttering as your tired, thin body, but in the eyes of the students is so firm: your tears wet your clothes, and you know that in the eyes of the students, it is the most perfect sculpture in the world under your feet.

Dear teachers, your light and heat are limited, but it is your limited light and heat that merge together to ignite the light of the motherland's take-off!

Finally, I wish all teachers a happy holiday again!

This theme is generally an expression of gratitude to the teacher.

That's the right thing to do with that.

Detached from this theme, it would not be Teacher's Day.

You can put a lot of mysterious things in the classroom, show it in the beginning, hang some ** on the wall, or ornaments, or you can have a happy moment with the teacher, everything can be imagined by yourself.

Carry out reading activities and express gratitude to teachers.

Hold a party, everyone has fun, and then, send some small gifts to the teacher, small household appliances or something.

Someone in the group gave this answer: Here I will briefly say, let's use a few calculation formulas.

1.The owner's discounted price (25) + the money the waiter hid (2) = the total cost of the traveler (27).

2.Passenger's original cost (30) = discounted fare (25) + owner's return money (5) 3Passenger's original cost (30) = Passenger's current total cost (27) + Passenger's last refund (3).

4.The refund money received by the traveler (3) + the money hidden by the waiter (2) = the return money of the store owner (5) 5That is to say, in the end, the amount of money spent by the three passengers includes the part that was hidden by the waiter, so if you ask for the total amount, it is not the money hidden by the waiter, but the refund of the 3 yuan that the passenger received at the end.

So, it's just a trap of logical deviation, and the money didn't fly away from beginning to end!

The mistake is "27+2=29".

27 and 2 can't be added together, 27 is the money paid by three people, and 2 is hidden by the waiter, what is the sum of the two equals, nothing is equal to, the boss collects 25 + the waiter hides 2 = the accommodation fee paid by three people 27, each of this equation has a specific meaning, think about it: the amount paid by three people 27 + the waiter hides from 2 = 29, these 29 have no specific meaning, that is to say, two things that should not be added together are added together, causing confusion in the concept.

We can look at it this way, the 30 yuan boss kept one yuan, gave two yuan to the waiter, and refunded 9 yuan to one of the three customers.

Isn't this 1+2+3x9=30

This question has been asked by many people, and it is caused by problems in the statistical field. Search the Internet for a lot of answers.

In fact, the boss took 25 yuan, the waiter took 2 yuan, and returned 3 yuan = 30 yuan, where is less.

Today you are my pride, tomorrow I am your pride.

Respect teachers and education, and lay the foundation for the future.

Sample essay on the theme of Teacher's Day:

Today is September 10th, Teacher's Day, and it is also the birthday of our teachers.

In the morning, as soon as the teacher came to the classroom, the students rushed to give Teacher's Day gifts. In an instant, the originally empty lectern was full of gifts, including water cups, ** boxes, candles, and what shocked me the most was that there were bags and so on, anyway, there were a lot. The teacher was overjoyed.

After class, the teacher asked the four students to put the gifts in the office. It is estimated that the teachers of other classes will be envious, jealous and hateful when they see it.

In the afternoon, I came to school and saw that Wang Ao of our group brought a bouquet of flowers, wow, so beautiful. At this moment, I don't know who said: The teacher is here.

We just wanted to surprise the teacher. I don't know who shouted, 'Hide, everyone'. We hurried out of the classroom and hid on the back balcony.

Some people worry about whether the teacher will see the car when he puts it from behind. With that, we collectively moved back again. Don't talk, the teacher is coming. We asked the teacher to squint into the classroom, and then the teacher opened it, and the teacher saw the cake on the lectern at a glance.

The teacher couldn't have been happier. We sang the birthday song afterwards, and the teacher cried, which was a tear of happiness. After blowing out the candles, the teacher said that he wanted us to eat cake together. One piece for a group. Our group ate with relish, and even grabbed it, which was very happy.

This Teacher's Day, we had a very happy time, after all, this is the first time to eat cake on Teacher's Day.
