Tornadoes begin with a thunderstorm but not just any thunderstorm.龙卷风的开始是雷暴，但是却不止是普通的雷暴。These are especially powerful, towering thunderstorms called supercells.非常强大，非常激烈的雷暴，被称为超级雷暴云。Reaching up to over 50,000 feet, they bring high force winds, giant hails...
例如: Can you explain how lightning is formed during a thunderstorm? 你能解释一下雷雨天为什么会产生闪电吗? 3.比较程度: - How much more 例如: I can't believe how much more progress she has made compared to last year. 我简直不敢相信她和去年相比进步这么大。 - How far ahead 例如:She is...
