双卡双待的“双”不是"two“也不是”double"

双卡双待英文怎么说?
双卡双待:

双卡双待的“双”不是"two“也不是”double"
为什么这里的“双”是dual而不是double?
我们先仔细看一下这两个词的解释
dual
adj. /ˈdʒuː.əl/
with two parts, or combining two things
两部分的;二元的;双重的
例：
This room has a dual purpose, serving as both a study and a dining room.
这个房间有两个用途，既作书房又当餐厅。
the dual role of chairman and chief executive
董事长和首席执行官的双重角色
dual nationality/citizenship 双重国籍
dual SIM 一部手机同时使用2个SIM卡
double
adj. /ˈdʌb.əl/
twice the size, amount, price, etc., or consisting of two similar things together
两倍的;成双的;双份的
Dual和double的区别
dual和double都表示“双”，而dual强调同时的，双重的，一个物体的两面;double则强调数量上(量级的)两倍。你可以说一个手机装有2个SIM卡但是那并不代表这2个SIM卡在这部手机上都可以同时使用，从这一层面上讲dual才是“双卡双待”最佳的用词。简单一点理解，dual就像是双黄蛋，double则只是两个蛋黄。
例：
According to the code we can expect a new iPhone that comes with dual SIM support, in a first for Apple.
根据编码，我们可以看到新的iPhone将支持双卡，这也是苹果首次使用该功能。
再补充一点
SIM的全拼是
“Subscriber Identification Module”，
意思是“用户身份识别模块”

"It was a tough match. I knew that even if I won the first set, it was going to be a tough battle," Halep said on-court after the match. "I knew that she's a very powerful opponent and I had to stay very focused until the end.

"In the second set, she raised her level, definitely, and maybe I did some easy mistakes and wrong decisions. She played very well and it was really difficult to finish the match in two sets."
