此处，namely引起了一个意合，要求两端的形式尽量一致。那么，为啥读者读到的最后版本的句子和上面这个不同呢?原因很简单，就是命题者依据避免主语过长的原则，把namely后面的半截移到了句子最后，进一步加大了题目的难度。这一招在其它题目也出现过，请看这题：
GWD-11-Q33:
After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.
A. tested that could eventually propel aircraft anywhere in the world within two hours or help
B. tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help
C. tested, eventually able to propel aircraft anywhere in the world within two hours, or helping
D. tested, and it eventually could propel aircraft anywhere in the world within two hours or helping
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help
that从句实际上修饰的是engine，可是被挪后了，目的也是为了减少主语的长度。
延伸：老头连namely都能编出意合的题目，所以请一定留心能表达出两边相等关系的东东，如be动词，A means B等等。
第二类：暗度陈仓—形式并列松散，逻辑呼应紧密
188. (28112-!-item-!-188;#058&002759) (GWD-7-Q33)
The health benefits of tea have been the subject of much research; in addition to its possibilities for preventing and inhibiting some forms of cancer, the brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke.
A. in addition to its possibilities for preventing and inhibiting
B. in addition to its possibilities to prevent or inhibit
C. besides the possibility that it prevents and inhibits
D. besides the possible preventing and inhibiting of
E. besides possibly preventing or inhibiting
此题咋看着 in addition to或者besides不知道怎么用，因为很多人生硬地认为主语和in addiction to 之后的东西应该平行，其实不然，该题的妙处，也是在于意合，读者需要判断，“防治癌症”这事儿，到底和句子中哪个地方有资格构成“意合”?
如果还没看出，请允许我重温一下老头挪位置的常用伎俩，看看这个被我挪过的句子：The brewed leaves of Camellia sinensis may also play a role in reducing the risk of heart disease and stroke, besides possibly preventing or inhibiting some forms of cancer
这会儿看明白了吧，实际上，他们需要和in reducing the risk of heart disease and stroke平行，本题答案也呼之欲出了。当然，本题还有其它看点，容后再述。
有了这题的基础，大家应该会比较明天PREP里面大家一直郁闷的两题，答案是怎么回事，因为， In addition to 到底和谁平行，不是由谁放在主语说了算，而是意思说了算!
In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting East African cave paintings.英语作文
