It is also mandatory for low-voltage host to send CMD8 before ACMD41. In case that a Dual Voltage
Card is not receiving CMD8 the cardwill work as a high-voltage only card, and in this case that a lowvoltage host didn't send CMD8 the card will go to inactive at ACMD41.
英文描述得再清楚不过了，首先就把重点亮出来了：
It is also mandatory for low-voltage host to send CMD8 before ACMD41.
告诉你必须在发送ACMD41之前发送CMD8，这是强制性（mandatory）要求。
这一条是针对low-voltage host来讲的。
再阐述不这样做的后果，分两种情况：
一、
In case that a Dual Voltage
Card is not receiving CMD8 the cardwill work as a high-voltage only card,
对于dual voltage card，工作于high-voltage模式。
二、
and in this case that a lowvoltage host didn't send CMD8 the card will go to inactive at ACMD41.
会进入inactive模式。
楼主
每个单词都查过的 ..有道词典 ,,,,但是 你懂的 句子太长 
翻译的挺好啊,在qq群里问了下有人简要说了下, 我是理解了,然后不知道怎么描述她翻译这个句子
最近在弄SD卡 你弄过么 
如果你单纯的直接翻译,太牛了
