Chopsticks (or kuaizi in Chinese) are a kind of common tableware in the world. They are widely used in Asia and overseas Chinese communities. Chopsticks are also one of the symbols of Chinese food culture.
There are many stories about who may have invented them. About 3,000 years ago, our ancestor called Dayu helped people fight against floods. He was always busy and often ate in the wild. To save time, he used two branches to get the food. He found this way was more convenient than using hands. People followed him to use chopsticks to eat. In fact, the earliest chopsticks were invented more than 3,000 years ago, dating back to the Shang Dynasty. Around AD 500, the use of chopsticks spread from China to some countries in Asia like Japan, Vietnam and Korea.
Chopsticks are usually 7 cun and 6 fen long. Cun and fen are Chinese units of measurement. 7 cun 6 fen is about 25.3333333 cm. Chopsticks are round at one end and square at the other. In ancient times, the wealthy had their chopsticks made of silver, gold, jade or other precious materials. Nowadays, they are made from different materials.
Although chopsticks are ordinary sticks, there is some Chinese philosophy(哲学) in them. The round end stands for the sky and the squared end stands for the earth. They are always used in pairs which is full of best wishes. Chinese like even numbers(偶数) because pair in Chinese is a very lucky word. So a pair of chopsticks can be used as the wedding gift. It means "to have a smart baby soon".
Meanwhile, there are some customs to use chopsticks while eating. Remember not to use chopsticks to hit the side of your bowl or plate to make a lot of noise. Never use them to point at others or to put them into rice directly. They are considered as impolite manners.
Chopsticks are commonly used in Chinese daily life, and they are full of Chinese culture.

### 三、阅读与回答问题
筷子（中文称“筷子”）是世界上一种常见的餐具。它们在亚洲和海外华人社区被广泛使用。筷子也是中国饮食文化的象征之一。
关于谁发明了筷子有很多故事。大约3000年前，我们的祖先大禹帮助人们抗洪。他总是很忙，经常在野外吃饭。为了节省时间，他用两根树枝夹食物。他发现这种方式比用手更方便。人们跟着他用筷子吃饭。事实上，最早的筷子发明于3000多年前，可追溯到商朝。大约在公元500年，筷子的使用从中国传播到亚洲的一些国家，如日本、越南和韩国。
筷子通常长7寸6分。寸和分是中国的度量单位。7寸6分约为25.3333333厘米。筷子一端圆，一端方。在古代，富人用银、金、玉或其他贵重材料制作筷子。如今，它们由不同的材料制成。
虽然筷子是普通的筷子，但其中蕴含着一些中国哲学。圆的一端代表天，方的一端代表地。它们总是成对使用，这充满了美好的祝愿。中国人喜欢偶数，因为“双”在中文里是一个非常吉利的字。所以一双筷子可以作为结婚礼物。它意味着“早生贵子”。
同时，吃饭时使用筷子有一些习俗。记住不要用筷子敲碗或盘子的边发出很大的声音。永远不要用它们指着别人或直接把它们插进米饭里。这些被认为是不礼貌的行为。
筷子在中国日常生活中很常见，并且它们充满了中国文化。
