4.    (24589-!-item-!-188;#058&001492)

As well as heat and light, the Sun is the source of a continuous stream of atomic particles known as
the solar wind.

(A) As well as heat and light, the Sun is the source of a continuous stream
(B) Besides heat and light, also the Sun is the source of a continuous stream
(C) Besides heat and light, the Sun is also the source of a continuous streaming
(D) The Sun is the source not only of heat and light, but also of a continuous stream
(E) The Sun is the source of not only heat and light but, as well, of a continuous streaming  

根据解释，C不选的原因是“heat and light与Sun并列，不符合逻辑；stream是名词，不需要用动名词形式streaming”
请问是不是besides 后面的名词和句子的主语都是并列的关系？谢谢

个人觉得besides的使用需要分来年两种情况：（在句首使用）
1.Besides doing (sth),SVO——S为逻辑主语来考察doing的使用是否符合逻辑
eg：Besides being heartbroken, she felt foolish
2.Besides sth，SVO——S与sth应是同类事物的描述。

141. Unlike transplants between identical twins, whose genetic endowment is the same, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.

(A) Unlike transplants between identical twins, whose genetic endowment is the same

(B) Besides transplants involving identical twins with the same genetic endowment

(C) Unless the transplant involves identical twins ，who have the same genetic endowment

(D) Aside from a transplant between identical twins with the same genetic endowment（C）

(E) Other than transplants between identical twins, whose genetic endowment is the same

OG:In A and B, the phrases beginning Unlike... and Besides... modify patients, the subject of the main clause; thus A absurdly states that Unlike transplants..., patients... must take... drugs, and B that all patients except for transplants... must take... drugs. （逻辑主语错：除了移植。。。病人）

既然OG已经给出了解释和倾向性，那就当做一种排除错误选项的方法比较好
