Kids often get confused by the term grandparent and great-grandparent .
孩子们常常弄不清祖父母和曾祖父母这类称谓。
In some cases , entire families are surviving on the pension of a grandparent .
甚至，有些家庭仅能依靠祖父母的养老金维持生计。
Japan , which has already had lots of practice with older consumers , has developed some ingenious new products for the grandparent generation .
日本在服务老年消费者方面经验丰富，已经为祖母一代开发一些制作精巧的新产品。
It probably would be akin to that of a child and an aunt or uncle , or even a child and a grandparent .
也许会类似于孩子和叔叔阿姨之间的关系，甚至像孩子和祖父母之间的关系。
This could be because they can be more certain than any other grandparent that the child is part of their genetic line , with dna that has not been tainted by affairs , and so worth the investment .
