and和because although的两个疑惑

2 and和because although的两个疑惑

①That will have to rise, because although the yold will constitute a bulge of comparative health and activity over the next decade, by 2030 they will hit 75—and enter a long period of decline for which few rich countries are ready.

请问老师这里的because although是可以连用的吗？

②By continuing to work, and staying socially engaged, the boomers, in their new guise as the young old, will change the world, as they have done several times before at different stages of their lives.

请问老师这句话中的and是连接 by continuing to work 和 (by)staying socially engaged in their newguise as the young old两部分吗？

那么下面这句话中的and in particular中的and可以删去吗？学生对and的用法有点困惑。

③The most important is public attitudes towards older people, and in particular the expectation that 60-somethings ought to be putting their feet up and quietly retiring into the background.

感谢老师的解答！

1 because从句本身是个主从复合句，although...the next decade为其中的让步状语从句，by 2030 they will...are ready 为其中的主句。你读句子视野要开阔，不要只看到相邻的一两个单词。再如下句：Everyone has to eat, because if he doesn't eat he will die of hunger. 你是不是又会问：怎么because后接if了？

2 介词by后接并列的动名词短语。by doing A and doing B.

3 and in particular the expectation...为补充语，是对public attitudes towards older people的补充说明。and可以删去不用。
