1. Introduction to volle'↔"yball
Volleyball is one of the b¶★♥all sports. The stadium is rectangular, wi™★≈Ωth high nets in betweπ←en. The two sides of the game (six people ≈ '♣per party) each occupy one side↕Ω≈ of the course. The players use the ball to h♣•''it the ball from the Int&ו±ernet. The ball used in volleyball is made of s™heepskin or artificial leather. The ru←↔£↕bber is bold and the size is similar¶σ to football. The sport originated in the United £βStates and was invented in 1895 by a s÷★ports staff named William G. Morgan in Holy Yoβ±rk, Massachusetts. In the early days, volleλ§∑yball was called Mintonette (th☆♣αe meaning of the small net). In 1896, accor' §ding to the characterist☆☆ics of the game, Professor ≈↑Holstad proposed to change to Volleyball (₩×₽the air hitting ball), the✔₽ modern international name Volleyball (volle©★₹©yball). At that time, the official ball circum✘<∞ference was 25 to 27 inches (about 63≤Ω.5 to 68.8 cm) and the weight∞Ωπ≤ was 9 to 12 ounces (about 255 to 3ε§₽♦46 grams). The materials and production technique≤βs of the ball used in modern internati•₩>onal competition have chang >¥£ed a lot, but the specif"←"∞ications of the ball ar↔ 'e similar to the previous ones.
