答案及解析:
- P) G3 y5 K; K; ~# f5 u% ~6 Y! T1. decreased -%26gt; increased
: D7 Z  x5 o' V+ e5 g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。

2. people后加who或that
4 ^+ Y+ U4 ?/ p4 n$ m8 {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。
, n; O  Q2 {+ _8 j8 T5 f# }
9 A3 E; K4 W5 S! N# V, V3. provide后加for
5 q" ~8 T3 K- A! y& W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。

7 T7 j+ {) w  S- Q4. could后加not
7 B/ D/ {& C9 n7 p, f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。

5. live -%26gt; alive
这里是词组keep sb alive。
, [/ c5 c* x8 ]1 t7 s8 ]- X* D) Y+ c8 \
8 ~7 V& `* }# H- n$ _6. in -%26gt; at
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。

. |* e9 w1 @9 E7 Q/ c7. 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”。

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。
! d( v, l0 R- A- Z% ?, N
& v9 ~1 r, E& S9. 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。
! n+ M; E3 F( x: t( n' S* K
4 w5 V4 R& T% ]: g' G10. 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。
