1. as well as是as…as的结构，表示与…一样好。
第一个as是副词，第二个as是连词，引导比较状语从句。
Eg：She doesn’t play the piano as well as you do. 她弹钢琴不如你弹得好。
用法同as much as的用法：I love her as much as you do. 我和你一样爱她。

b. A as well as B 用作句子的主语时，谓语动词须同A保持数的一致。例如：
The girl, as well as the boys, has learned to ride.
Aluminium as well as most metals is a good conductor.
2) 连接动词。as well as 后跟动词时，该动词通常用动名词的形式。
She sings as well as playing the piano. 她不但会弹钢琴，而且会唱歌。
He sits late at night as well as working hard during the day.

(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gases having
(C) of comparable size, and also they emit far fewer carbon dioxide and other gases that have
(D) that have a comparable size, and also they emit far less carbon dioxide gas and other gases that have
(E) that have a comparable size, as well as emitting far fewer carbon dioxide and other gases having
朗文例句：The organization gives help and support to people in need, as well as raising money for local charities.
3) 如果as well as连接的是两个简单动词形式，它和第二个动词实际上起着插入语的作用，那么，第二个动词则是限定动词，即与主语保持人称和数的一致。
Gasoline marketing is undergoing major changes as stations often not only add convenience stores but also combine with major fast-food chains to build complexes where customers can shop and eat as well as buy gasoline.
He works, as well as sleeps, in the room.

We are repairing the roof, as well as painting the walls.
You ought to play games, as well as study books.
There still remain a lot of problems for us to investigate as well as solve.
5) as well as位于句首时，as well as是介词短语，用法类似like、unlike，意思是“除…之外”。介词短语置于句首时，其逻辑主语等于句子主语，其连接对象必须是同类对等事物。
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

(E) to natural processes such as shoreline recession, rising sea levels, and destructive hurricanes, as well as to

OA:B。句子结构：…, Abu Ali al-Hasan ibn al-Haytham, …, experimented extensively with light and vision, laying…
Ranked among… 修饰句子主语，laying the foundation作分词状语表结果。正确的句子中，the foundation for modern optics and for the notion平行对称，be based on experiment as well as on arguments平行对称。

8) 在表达“不但……而且……”的意义时，“A as well as B”结构的侧重点在A；“not only A … but (also) B”和“A and B as well”结构的侧重点在B。试比较：
The house has a back door as well as a front door. = The house has not only a front door but also a back door.
You as well as I are wrong. = Not only I but also you are wrong.
不过，as well as语气不如not only…but also强，其语意也不及后者明朗清楚，有时甚至毫无“侧重”可言。例如：
9) As well as与and的区别：摘自prep07笔记。
[1]As well as表示同样、也等意思，应为解释为：in addition to something or someone else。它与and是有区别的，不能简单的认为 as well as等于and：
a)意思上：A and B结构中，A与B平行，属于同一层次；而A, as well as B这一结构中，B是对A的补充，并非同一层次
b)谓语动词：以A and B作主语的句子，主语包含了含义平行的同一层次的A和B两者，所以谓语为复数；而以A, as well as B做主语的句子，主语的核心只有A，B是顺带提一下的补充句意性质的成分，因此谓语的人称和数由A的人称和数决定
c)多个名词平行，同时使用到and和as well as的结构，我们可以使用：A, B, and C, as well as D。其中，ABC是同一个层次的事物，它们之间是同一层次的平行关系，D是对ABC的一个补充，严格上来说和ABC不属于同一个层次。同理，(both) A and B, as well as C 也是正确的，AB属于同层次的事物，C是对AB的一个补充。
d)如果出现 be vulnerable to A, B, as well as C 这种句型，我们认为是错误的。因为as well as和and是有区别的，as well as不能代替and。上述句型，如果ABC属于同一层次，则应改为A, B, and C. 如果AB同层次，C是补充说明类的事物，则应该改为A and B, as well as C
[2]多个带to的结构平行时，可以考虑两种用法：要么全部都带to，要么只有第一个有to、后面的都不带。比如本题中，可以是be vulnerable to A, B and C，也可以是be vulnerable to A, to B, and to C. 其他方式的不正确。
Lenders and building managers in the southwestern section of the city report that because of the rental market in the area being renewed, as well as the willingness of the banks to lend money being increased, apartment buildings are being rehabilitated at a pace unseen for a decade.
(A) of the rental market in the area being renewed, as well as the willingness of the banks to lend money being increased
(B) of the renewed rental market in the area, as well as the willingness of banks to lend money increasing
(C) of the renewed rental market in the area and the increased willingness of banks to lend money
(D) the rental market in the area renewed and the willingness of banks to lend money increased, therefore
(E) the rental market in the area was being renewed and banks were increasingly willing to lend money, so
是否需要区别as well as和and的用法？From Ron
this is not a decision that you are expected to make -- in this context, either of those two phrasings could be legitimate.
in general, "and" is a default preference (because it's simpler) while "as well as" is used when there is some sort of rhetorical reason to do so.
this is not something i've ever seen tested, and i'm basically 100% sure it will never be tested (because the difference is quite subtle, much more subtle than anything that would actually be dispositive in an official gmat problem). so it's nothing to worry about.
