一： OG261
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
我知道其中A的错误之一是说时间先后搞反了，但是OG还说了A一个错误，In A, the phrase Being a United States citizen since 1988  and born in Calcutta in 1940 violates parallelism。为什么说这两个短语违反了平行。是因为一个是现在分词短语，一个是过去分词短语吗？ 但是我记得有一个这样的SC题目：
l1．The growth of the railroads led to the abolition of local times, which was determined by when the sun reached the observer's meridian and differing from city to city, and to the establishment of regional times.
（A）which was determined by when the sun reached the observer's meridian and differing
（B）which was determined by when the sun reached the observer's meridian and which differed
（C）which were determined by when the sun reached the observer's meridian and differing
（D）determined by when the sun reached the observer's meridian and differed
（E）determined by when the sun reached the observer's meridian and differing
答案是E，也是过去分词短语和现在分词短语并列呀。

being a united states citizen since 1988 and born in calcutta in 1940
分词短语的构成是不同的：前面的是分词+名词；后面的是分词+介词短语
determined by when the sun reached the observer's meridian and differing from city to city
前后都是分词加上介词短语。
