问题补充：
All the Harry Potter books by Joanne Rowling, a poor single mother in Edinburgh, all over the world.
A. lives; are well sold
B. living; sell well
C. lives; sell good
D. living; are well sold
答案：
A. lives; are well sold
(答案→)B. living; sell well
C. lives; sell good
D. living; are well sold
解析：考查动词。本句话的真正主语是AlltheHarryPotterbooks,所以第二个空应该填sellwell(卖得很好)。此处sell不用被动语态。livinginEdinburgh是现在分词作mother的后置定语。apoorsinglemother作JoanneRowling的同位语。句意：非常畅销的《哈利波特》系类书籍是一个住在爱丁堡地方的一个叫乔安妮·罗林贫困的单亲妈妈所写的。根据句意说明B正确。
