关于childhood的话题一直是雅思口语考试的高频话题，储备丰富的雅思口语素材是雅思口语高分的关键，针对这类话题，新东方在线雅思频道为大家带来80后童年零食：Pop Rocks/popping candy /跳跳糖，供大家参考。

　　Pop Rocks/popping candy 跳跳糖

　　Pop Rocks is a carbonated candy with ingredients including lactose (milk sugar), corn syrup, and flavoring. It differs from typical hard candy in that it creates a fizzy reaction when it dissolves in one's mouth.

　　跳跳糖是种含二氧化碳的糖果，原料包括乳糖、玉米糖浆、其他调味料等。它和普通硬糖的区别就在于跳跳糖融化在口中时会产生嘶嘶腾涌的反应。

　　Although still popular, Pop Rocks are regarded nostalgically as an aspect of 1970s pop culture.

　　虽然现在跳跳糖依然流行，但人们总是将它视作20世纪70年代流行文化的一部分来怀念。
