",and"的用法

jupiter410

我想问“，and”后面是不是一定加主谓完整的句子？

除了n,n,and n或者v,v,and v这种情况。

Rejecting the apprenticeship model of training social workers in philanthropic agencies, twentieth-century reformer Edith Abbott was convinced of social work education belonging in the university so that students could be offered a broad range of courses dealing with social issues. 

(A) of social work education belonging in the university so that

(B) that social work education should be in the university, and that

(C) about the importance of social work education belonging in the university while

(D) that social work education belonged in the university, where

(E) of the necessity of social work education being in the university and

比如这道题，正确答案是D.

有人说，B错在(B) that social work education should be in the university, and that

"，and"后面，一定是加完整的句子。

自己顶上去

terry_run

yes. 

And 是连词。“,and” 由于前面存在 "," 且这里只有2个成分，后面必须加主谓结果，如果同主语，则"," 去掉。

actually 这个句子最大毛病是后面的句子明显意思是对Univ 的补充，只能用D.

terry_run，谢谢你。

我还想请问，那么这个规则，可不可以推广到所有的“，连词”上呢？

A recent poll indicates that many people in the United States hold a combination of conservative and liberal political views; i.e., they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting many specific government programs for health care, education, and the environment.

(A) they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting

(B) they denounce big government--they say that government is doing too much and has become too powerful--but supporting at the same time

(C) they denounce big government, they say that government is doing too much and it has become too powerful, while they support at the same time

(D) while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting

(E) while they are denouncing big government--they say that government is doing too much and it has become too powerful-- supporting at the same time
        

答案为A

请看这道题目。

(A) they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting

A选项，是supporting在句尾做状语，修饰DENOUNCE，表示动作的同时进行，那这里的at the same time，难道没有语义重复的问题吗？

还有当分词ING形式做状语时，前面可以加while这种连词吗？ 

我这样理解对吗？

jupiter410

自己再顶上去！

terry_run

while here is making contrast ( 对比）, not "at the same time", so not 重复

while 是引导从句的连词(subordinators)，而不是连接句子成分的连词(and,but 等）

是有区别的，不能随便推广。

terry_run

补充 WHILE 除了引导从句外，当主从句主语一样时，可以直接加 doing

jupiter410

明白了！在做prep的时候，也发现了很多WHILE后面直接加doing的例子。谢谢~

可不可以请您总结一下

哪些是连接句子的连词，哪些是连接从句的连词呢？

我仿佛从来没有意识到过，连词还有连接句子的连词和连接从句的连词的区别。

谢谢了！
