所谓“长细节”，不是那种一两句话的短细节，而是多句、整段甚至全篇的细节理解。短细节只需常规的长难句理解能力就能应对，而长细节就不是那么简单了。
以下是几个长细节的例子，试试能否应对。
例1：一种蒸锅（steamer）
Advantages: This is a good, basic design which sits inside a variety of different shapes of pans with the water under it; a ring in the center allows for easy lifting and it’s easy to clean．
Disadvantages: It only holds small dishes. Also, if you put too much water in the pan, it will boil up through the vegetables and they will be watery. If you put too little water in and let it get dry, you will burn the pan and get strange-smelling vegetables．
问题：What can we learn about the folding steamer?
A．It comes in different kinds of shapes and sizes.
B．It is designed for large families.
