问题     人们在喜庆场合燃放焰火(firework)以增加节日气氛。焰火含有化学物质,点燃后会发出颜色形状各异的火花,绚丽夺目。最早关于焰火的记载出现在公元7世纪的中国。早在宋朝(the Song Dynasty),中国的普通百姓就可以从市场上买到焰火。焰火被用作庆祝活动的一部分。在现代中国,因为焰火很容易引发火灾,其使用受到法律的限制,在很多地方人们只能在春节的时候才能买到。

选项

答案 Fireworks are lit on joyous occasions to add to the festive atmosphere. They contain chemicals and after lighting, they will give out brilliant and eye-catching sparks with diverse colors and shapes. The earliest records about fireworks can date back to the 7th century China. As early as the Song Dynasty, common Chinese people were able to purchase fireworks from the market. Fireworks were used as part of celebrations. In modern China, because fireworks start fires easily, the use of them is legally restricted and in many places, people can only buy them during the Spring Festival.
