答案与题解：
1.E 根据本空的上一句：孩子们长大了，中年人期望有时间享受努力工作创造的生活，但是现实却不允许;所以后一句论证为什么会这样，即中年人因为上有老、下有小，所以不能无忧无虑地享受生活。
2.B 依据上一句：19世纪早期，美国人的平均寿命在40岁左右，而现在人们通常能活到75岁。人们寿命延长的结果是：孩子要照顾父母的时间也相应延长了。
3.C 该句是本段的主题句。本段其余几句都在讲照顾父母可能要面临的种种闲难，C是一总括句。
4.A 本段都在讲照料成人孩子面临的种种问题。these issues可以是一种提示，就是指上面提到的问题。
5.F 依据本空的后一句It can also provide a valuable opportunity to spend more time with them，可以断定这两句是并列句，also一词是提示词。
