Traditional Chinese folk music instrument.

There are many kinds of traditional Chinese musical instruments, including tanggu, flower drum, tambourine, taiping, book drum, elephant foot drum, cloud gong, cymbal, bell, chime, xiao, paixiao, octagonal drum, flute, suona, sheng, sanxian, ruan, pipa, gonghou, erhu, jinghu dulcimer, guqin, etc., and with the passage of time, new varieties are increasing, so it is necessary to classify. The earliest classification of musical instruments can be traced back to the time when it began in the Western Zhou Dynasty"Eight tones"。Its classification is based on the materials used to make the instrument, as contained in "Zhou Guan*Chunguan*Master":

The eight tones of all broadcasts - gold, stone, earth, leather, silk, wood, skull, bamboo. "Although this classification is not scientific, it has always occupied a traditional position for more than 3,000 years from the Zhou Dynasty to the Qing Dynasty, which shows that it has had a great influence on the classification of traditional Chinese musical instruments.

A hand-copied newspaper about the strong nostalgia of Bashan sorrow.

Don't go up to the heights to look far away, don't go to the beach to listen to the tide.

Acacia's heart, said to the moon, round and missing, missing and round.

The sycamore drips rain, dripping out of Bashan's sorrow, looking at the geese by the clouds, and looking out of the childhood night tour.

There has been excitement, there has been meditation, over the years, through the years, there is always a voice echoing in the ears:

Bury me on the high mountain, look at my hometown;

Hometown is invisible, never forget! ”

This poem, written with a lifetime of blood and tears, expresses the hearts and ...... of thousands of veterans who left the mainland in 49 years and parted for more than half a century

Nostalgia Xi Murong.

The song of the hometown is a clear flute.

It always rings on a moonlit night.

The face of his hometown is a vague melancholy.

It's like waving goodbye in the fog.

After parting, nostalgia is a tree without growth rings.

When I was a child, nostalgia was a small stamp.

I'm on this side, and my mother is on the other side.

Growing up, nostalgia is a narrow ticket.

I'm on this end and the bride is on that end.

Later, nostalgia is a low grave.

I'm outside, my mother is inside.

And now nostalgia is a shallow strait.

I'm on this side, and the continent is on the other side.

First, find out the meaning of certain words in the sentence

For example, "the difference between m and 13" and "m minus the difference of 13", both mean the same thing, and should be written as m-13, but not 13-m, that is, to find the difference between two numbers, the number given first should be subtracted, and the number given later should be subtracted, and the order of the two cannot be reversed

For example, "a is divided by 9", "9 is divided by a" and "a is divided by 9" has the same meaning, and should be written as a 9 instead of 9 a

For example, "the cubic difference between x and y" and "the cubic difference between x and y" have different meanings, the former should be expressed as, and the latter is

In order to avoid such mistakes, it is necessary to clarify the meaning of some important words in the question when reviewing the problem, especially to distinguish some mathematical concepts that are easy to confuse, so as to prevent the crown from being worn out

Second, grasp the word "of" in the sentence to divide the level

When analyzing the meaning of the topic, special attention should be paid to grasping the word "of" in the sentence to divide the hierarchy Here are two examples

Example: Algebraic expression: a number of c smaller than 3 times the cubic difference of a and b

Analysis: There are three "of" characters in the sentence, and we use different lines to draw different levels of the sentence according to their position

Let's start by expressing the "cubic difference of the numbers a and b":

Secondly, it means "3 times the cubic difference of the numbers a and b":

Finally, it is said that "the number of c smaller than 3 times the cubic difference of the two numbers a and b":

Clause. 3. Reverse training cannot be neglected

Translation "is always mutual" For example, when translating between Chinese and English, you should be able to translate English into Chinese as well as Chinese into English The same is true for algebraic "translation", which requires both practicing "translating" everyday language into algebraic language and practicing "translating" algebraic language into everyday language Practice from both positive and negative aspects can integrate and promote each other
