111. 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 988．she was born in Calcutta in 1940；author Bharati Mukheqee

(C)  Born in Calcutta in 1940．author Bharati Mukheqee 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 Mukhedee

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

The correct answer is C.

My question is:

选C后逗号的作用:...;she has lived in England and Canada , and first came to the United States in 1961 to study at the Iowa Writers' Workshop.

这里加逗号是不是为了避免语法错误呢?　

如果不加逗号::...lived in England and Canada and (has) first came to the United States in 1961 to study at the Iowa Writers' Workshop.

会不会感觉好象省略了has而有语法错误呢?  has done...and has done...结构可以省略第二个has吗？

sorry sorry!

没有注意到是came,

QUOTE:

如果去掉逗号的话，第一是has lived和came时态不平行

那就是说,现在完成时不可以和过去时平行是吗?但我觉得she has lived in England and Canada and first came to the United ...也是可以说的通的啊？

谁能解释一下呢？

Born in Calcutta in 1940，author Bharati Mukheqee became a United States citizen in 1988；she has lived in England and Canada , and first came to the United States in 1961 to study at the Iowa Writers' Workshop.

我不理解勒first came前面怎么可能有个has呢...没见过哪有sb has...in 1961

susanyaki

我的理解是这样，因为come 的过去分词是come ，题目中用的是过去式came，所以如果去掉逗号的话，第一是has lived和came时态不平行，其次即便可以省略后一个has，这样has came也是不成立的，因为过去式是come

不知道说的对不对

用逗号是为了在句子结构上与分号前面的句子平行吧

这里应该是前后时态不一样所以必须有逗号，前面是一般完成时，后面则是一般过去时。。因为有时间状语in 1961 ，后面只能用一般过去时
