2023年高二暑假阅读理解题材类专练:说明文 （共4题） 一、阅读理解题（共4题） In Asia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure (结构), they are widely different in size and shape. Kite-fighting competitions are also held, in which competitors use their kites to attack and bring down their opponents' (对手) kites or cut their strings(线). For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite-flying classes for the children on an island in Hawaii.

Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!
