OG261关于逗号. 薰衣紫草MM曾经问过,但没有答案.

261. Being a United States citizen since 1988 and born in Calcutta in 1940, author Bharati Mukherjee has lived in England and Canada, and first came to the United States in 1961 to study at the Iowa Writers’ Workshop.

(A) Being a United States citizen since 1988 and born in Calcutta in 1940, author Bharati Mukherjee has

(B) Having been a United States citizen since 1988, she was born in Calcutta in 1940; author Bharati Mukherjee

(C) Born in Calcutta in 1940, author Bharati Mukherjee became a United States citizen in 1988; she has

(D) Being born in Calcutta in 1940 and having been a United States citizen since 1988, author Bharati Mukherjee（C）

(E) Having been born in Calcutta in 1940 and being a United States citizen since 1988, author Bharati Mukherjee

这里的C:

为啥在","后不加个代词呢? 引导一个新的从句.这样更好. 不加代词直接and连感觉有动词并列的嫌疑.

OG里有许多例子,如果动词并列,且主语为同一主语. 逗号后可以不加代词.如OG264. 但如果不是并列, 好象要用从句引导比较好吧?  这个待证实.

大家讨论讨论?

she has lived in England and Canada, and first came to the United States in 1961 to study at the Iowa Writers’ Workshop.

感觉省去了主语，避免重复she，应该是“she。。。。。”

但是就算是动词并列的话是不是也有特殊情况？

因为有 in 1961 这个时间标志，只能使用一般过去时，

动词的并列在没有时态标志的时候，需要完全一致，

但是如果有明确的时态标志或者时明显的逻辑先后的概念的话，动词的并列形式也可以不一致吧

大家讨论

是不是主语一致时, 即使有逗号,后面也不要再加主语了?

我觉的得看情况

1.如果没有明显的不同时态标志，主语一致，谓语动词v1 和 v2不同时，宾语sth1，sth2不同，那我觉的句子：主语 + v1 + sth1，and + v2 + sth2可以接受，注意一点，V1和V2的时态得一致

2.如果谓语动词一致，就是宾语不同，那我觉的连"动词"也能省，但这时候逗号也必须省略

主语 + v + sth1+ and  + sth2

3.如果宾语一致，谓语动词不一样

我觉得，得看动词得逻辑前后关系，应该用and （then） +V

主语 + v1 + and then + v2 + sth这时得V1,V2时态必须一致。

加逗号得话，起码得用代词吧宾语补足

主语 + v1 + sth，and then + v2 + it/those/。。。。

比如，John bought the flour，and then cooked it。

4.如果宾语不一致，谓语动词不一样，且有时态明显不同，虽然省了主语，但是谓语动词的时态可以不一样

比如

mary has lived in shanghai science 1956,but went for school in Sweden( /in 1936/ten years ago。。。。)

我感觉首先要满足逻辑意思，再满足语法

佩服佩服~  偶得慢慢消化
