One of the nicest things to see while taking a hike on a chilly fall day are frost flowers, small formations of ice that are really not flowers at all.
2
They occur when water freezes in the stem of a plant.
3
Because liquid sap expands when it freezes, it is forced out from the stem in these beautiful curled ribbons.
4
Frost flowers occur only in late fall, after the first few hard freezes and while the ground is still warm.
5
Their season is brief and they disappear quickly on the day they occur, melting like frost when the air warms.

7
If you would like to see these flowers in the wild, keep your eye on the calendar and the weather and go when it starts to frost in the fall.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
