标题: OG11版紫皮-95，111

95. If Dr. Wade was right, any apparent connection of the eating of highly processed foods and excelling at sports is purely coincidental.

(A) If Dr. Wade was right, any apparent connection of the eating of

(B) Should Dr. Wade be right, any apparent connection of eating

(D) If Dr. Wade is right, any apparent connection between eating

(E) Should Dr. Wade have been right, any connection apparent between eating

答案是D。但是为什么未划线部分的主句是一般现在时呢？if条件句的主句不是要用将来时态吗？第一眼看到主句谓语是is，我都不知道选什么了。

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 1988, she was born in Calcutta in 1940; author Bharati Mukherjee

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

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

答案C. 但是为什么“；”后用的是现在完成时? 后面不是有and first came to......吗？难道不是两个一般过去时态的平行？

多谢大家指点！

就是阿，同问。在紫皮78和83中对if引导的条件从句有明确的解释亚

现在完成时有两种用法：describe an action that occurred at an indefinite time in the past or that began in the past and continues to the present.
前面的现在完成时态用了第一个用法。
后半句用了一般过去时，表示事件发生在过去的某一特定时间，事件一般是一次性的。

if开头的假设句，如果假设与现在的事实相反，要求用虚拟语气。

但是if 也可以表示对将来的推测，因为是对将来的推测，所以还不知道事情发生的可能性，一般用陈述语气来表示对一个未来事实的推测。

那就是说就算一件事情在过去发生并且已经结束了，只要我不知道这事发生的具体时间就可以用have done？怪怪的

完成时确实是指一个过去发生并持续到现在的动作。这里live可以理解为author的“一生”住过哪里哪里，把这当作一件持续发生事情。

比如，I have lived in LA, Washington and San Francisco; now I live in Shanghai. 这里不是说我现在还住在LA, Washington and San Francisco，但是我live这个动作从过去持续到现在
