Question

1、 Every time I go to a class reunion, for example, there are fewer and fewer still around.
2、when it says here that there aren't many of us left, that's absolutely right.
3、It then went on to say that he often thought about the good times they had had together when they both lived in the same neighborhood.

Answer 1

1、 Every time I go to a class reunion是状语从句, for example, 是插入语
there are 是谓语fewer and fewer是主语 still around是状语.
比如说，每次我去参加老同学聚会，来的人总是越来越少
2、when it says here that there aren't many of us left是状语从句,
that是主语's 是系动词 absolutely right是表语.
信里说我们这些人当中留下的不多了，说得一点不错。

3、It是主语 then went on to say是谓语 后面是宾语从句作宾语
其中 that是连接词 he是宾从中的主语
often thought about 是宾从中的谓语
the good times是宾从中的宾语 后面是省略that的定语从句
其中 they 是定从中的主语
had had 是定从中的谓语 宾语是省略的关系代词that
together是定从中的状语 后面是定从中的状语从句
其中 when是从属连词 they是状从中的主语
both是同位语 lived 是状从中的的谓语
in the same neighborhood是状从中的状语
.信中还说，他常常想到他们的好时光。。。。。。。。
