答案及解析:
/ e# Z' w' k% ^3 J0 ^2 J4 f1. decreased -%26gt; increased
/ g- J/ w$ j, t根据下文提示，退休的老年人由工作的壮年人为其提供生活补助，可知此处地意思是“人类寿命的延长会增加社会负担”，所以此处应该用increased。

4 U1 g4 @+ G. z  p- V) c2. people后加who或that
9 ~2 d+ Y: z  V; v! t: t1 Z9 A0 Z分析句子结构，此句出现了两个谓语（系动词）are，故有一个必是从句。根据句子的主干可知，前部分are disable or too young or too old to work应该是定语从句，且缺少了引导词，又因为先行词是people，故加上相应的引导词that或who。
# S* e. ^# u3 s6 }
' l# `8 {- p; X, d3. provide后加for
此处从句的意思是“没有工作能力的人由有工作能力的人来养活”。provide for sb是“养活某人”的意思。
% ]0 \, f) x; A5 M* F
) ], w1 ~" r4 |# T4. could后加not
根据上下文理解，此处的意思应该是“老年人跟不上时代步伐，将被弃之不管或死去”。故要在could后加not。

/ t: F7 A. W: j! D5. live -%26gt; alive
: U  ^! |5 y+ z. q, l+ c( @3 `$ V这里是词组keep sb alive。

" b$ [6 Z. T2 i5 p7 k+ Q! J6. in -%26gt; at
1 O- l+ Q# Z1 m5 B9 F3 p; _) n此处的意思是“今天还有很多人超过了能够工作的年龄…..”。定语从句的先行词是age，复原后的词组是at the age。故用at which。
4 s) k& B- \) f/ t: Y3 R
7. If -%26gt; Unless
意思是“除非人们能位退休后的生活存钱，否则必须由别人来养活他们”。
2 Z" J0 j' H6 Z8 v4 g2 z
8. considerable -%26gt; little
根据上下文的理解，在美国，许多人靠社会救济生存，这笔钱很少，以至于人们生活在贫困的边缘。

9. Elder -%26gt; Older
elder意为“年龄较长的；资格老的，地位高的”，older意为“上年纪的”。此处指的是老年人，故用older。
, O" B4 G$ e& X1 ~/ E
$ V  T5 _1 P& M3 r6 s10. therefore -%26gt; unless
意思是“除非他们富有或有政府或私人的保险，否则生病时只能依靠救济金”。故将therefore改为unless。
