ople to enjoy prosperity, new economic policies will be required.
[A] to name a few [B]let alone [C]not to speak [D]let’s say
（答案为B）
2）如果平行的两个成分在形式上是介词短语，而且介词相同，一般说来第二个介词不要省略。如：
At times, more care goes into the composition of newspaper and magazine advertisements than into the writing of the features and editorials.
（三）代词及其指代一致
一．代词的指代
1．that的指代作用
that指代不可数名词和单数可数名词（如是复数，用those），后面通常跟有修饰语，如出现在比较结构中的that of。如
Conversation calls for a willingness to alternate the role of speaker with that of listener, and it calls for occasional “digestive pauses” by both.这里that指代前面的the role。
No bread eaten by men is so sweet as that earned by his own labor.
2．one的指代作用
one指代带不定冠词的单数可数名词，复数为ones。the one指代带定冠词的单数可数名词。如：
A good writer is who can express the commonplace in an uncommon way.
[A] that [B]he [C]one [D]this
答案为[C]
3．do的替代作用。
do代替动词，注意数和时态的变化。如：
For him to be re-elected, what is essential is not that his policy works , but that the public believe that it does.
二．代词指代一致问题
代词指代一致是指指代的名词在性、数、格上是否一致，或者所照应的名词词组在某些方面保持一致。
Each cigarette a person smokes does some harm, and eventually he may get a serious disease form its effect.
这里he指代前面的person。
It was during the 1920’s that the friendship between the two American writers Hemingway and Fitzgerald reached its highest point.
这里its指代前面的两人的friendship。
Our department was monitored by two supervisors, Bill and me.
这里me必须用宾格形式。
代词指代一致必须注意以下几个原则和规律：
1．邻近和靠近原则
由either … or, neither…nor, not only…but (also)连接先行词时候，
