问题补充：
for children, the album became popular with parents it came out.
A. Designed; when
B. Designed; immediately
C. To design; as soon as
D. Designing; as
答案：
A. Designed; when
(答案→)B. Designed; immediately
C. To design; as soon as
D. Designing; as
解析：考查过去分词做状语和连词：句意：因为是为孩子设计的，这个唱片一出版就很受父母欢迎。第一空是过去分词做状语，因为the album和design是被动关系，第二空表示“一…就”可以用as soon as或immediately。选B。
