Simplify | a | + | C-B | - | A-B | + | a + C | - | B | known C < a < 0 < B

Remove the absolute value
The original formula = - A + [- (C-B)] - [- (a-b)] + [- (a + C)] - B
=a-c+b+a-b-a-c-b
=a-2c-b

Read "a bowl of water" this text, with a few words to express your feelings

You see, the little squirrel's tail is erect, and his eyes are so bright! He takes a sip of water and quickly wipes his mouth with his paws, "squeak, squeak!"
When mountain magpies come, love stops on the pine tree. One of them flies down first, "magpie, magpie, magpie!" it greets its companions: "come on, come on!" everyone flies down and jumps by the spring, leaving their footprints on the wet sand
Yo, there are many claw marks on the wet sand, some like bamboo leaves, some like plum blossom
This bowl of water, the old people say it is a spring. No wonder the birds drink its water and sing so beautifully; the little squirrel drinks its water and looks so smart; the dolls in the village drink its water and are so smart one by one
Ah, it's the milk of Dashan. Its water is so sweet!
How you feel:
This clear water moistens all things and makes the earth full of vitality. He dedicates his sweetness to the world and sprinkles a piece of rain for the living beings
I wrote it myself

Reading passage: my father taught me the answer to the song

1. On a stormy night, my father taught me to listen to songs for the first time. What did I hear and what changed?
2. Read the third thing and talk about the meaning of the sentence "in the growth of a little girl, I also heard the music of my life"
3. My father taught me to appreciate the most wonderful music in the world
"I" heard the sound of the clarinet, I was no longer afraid, and slept better
"I" in the Church of little girls at the same time, I also understand a truth: not only to listen with ears, but also to listen attentively. Once you hear the song in your heart, no matter where you go, you will hold your head!
Although my father's music is not very good, but my father has a special way to teach me to enjoy the most wonderful music in the world!

My hobby listening to music
800 words

"If I want to be reincarnated, I am willing to devote my life to music. Music is the cheapest thing in the world, which can be enjoyed without causing adverse consequences." Sidney Smith once wrote so affectionately in his autobiography. Music is the common language of all mankind, the edification of human character and soul, and the catalyst of human progress, He is also a close friend
Music, in my heart, not only expresses a kind of emotion, but also a kind of soul, a kind of sacred nobility!
I enjoy classical music. In my spare time, I will enjoy a cup of bitter tea, look at the clear sky outside the window, turn on the stereo, and let the music drift, sublimate and precipitate in the floating air. Listening to Beethoven's symphony of destiny, I will sigh about the passion and struggle of life; listening to Ode to joy, I will admire the deep life experience of musicians, The unremitting pursuit of life; I prefer a Bing's "Er Quan Ying Yue", the sad sound of Erhu slowly out, I seem to see the protagonist in a bright moonlight, next to the clear spring, telling the infinite sadness in my heart. I will listen attentively and think, every detail in the music, even a small trill, It will also make me tremble. Touching music, often cause my resonance, wandering in my heart
I'm also optimistic about pop music. Pop music is simple and palatable. With the cooperation of a variety of musical instruments, the notes become three-dimensional. It seems that there is a trend of radiation and expansion, and there are hidden sounds that you can hear or can't hear. Pop music is not only because of its beautiful melody, but also because of the meaning of the lyrics. In those years, a song "often go home" was popular all over the country, The lyrics of Jay Chou, the little king of heaven, are full of elusive rhythm. A song of "class two in three years" says, "how strong is the first place in the world and how many hurdles do you want to pass? Can I be my own judge without this award?" it makes me infatuated and more aware of the real meaning of competition
For me, music is like a typhoon, sweeping my little world, like a spring rain, moistening my heart, like a rainbow, stealing my endless reverie. I love music, it is an indispensable part of my life!
