这个地方as well as比 and好。
And除了有dymmetric construction的用法之外( e.g. There is a copy on the desk and in the top drawer), 还具有asymmetric constructions的功能。分一下几种:
1 Temporal sequence ' X and Y' implicates ' X and then Y'
Where the coordinates denote occurnces rather than states, the linear order generally reflects the temporal sequence of the events:
e.g. He got up and had brakfast
2 Consequence: 'X and Y' implicates ' X and therefore Y'
Another common implicature is that the event expressed in the second coordinate is not only later than that expreesed in the first but also a consequence of it:
e.g. I fell off the ladder and broke my leg.
3. Condition ' X and Y' implicates ' if X then Y'
Closely related to consequence is condition
e.g. I expreess the lightest reervation and he accuses my of disloyalty
Come over and you'll be able to see better.
4. Concession ' X and Y" implicates ' despite X'
Here we have a " nevertheless/ despite" relation between a second coordinate verbal phrase and thre first
e.g You can eat as much of this as youlike and not put on weight
5. Temporal inclusion ' X and Y ' implicates " X while Y"
In informal style and may be interpreted as " while"
e.g. He came in and I was still asleep
AS WELL AS
Campbridge上对as well as作为coordinator与and用法区别的解释和OG一样。读下文
As a coordinator, as well as is restricted to subclausal coordination: She plays the piano as well as she sings lieder, for example, has only the literal comparative interpretation. Even as a coordination, 'X as well as Y" differs from "X and Y" in that the second term is backgrounded: Y often expresses information that is dicourse-old,(如携隐MM说的第二个动作或叙述的事情已经发生了) i.e. familiar from the prior discourse.
另外as well as can be construed syntactically in two ways, introducing an element that is either coordinate (e.g. She means what she says as well as says what she menas) or subordinate (e.g. Beauty as well as love is redemptive)
miaoyin你这个知识点满好的！OG里有很多次在解释其他答案不用and的时候都说打破了因果关系。
关于X as well as Y，基本就是这两点了：
1. Y发生在X之前，是一个backgroud的内容
2. Y是从属关系，X才是句子强调的重心（这个同样适用于阅读）
增加一个as well as的例子：OG221
221. Eating saltwater fish may significantly reduce the risk of heart attacks and also aid for sufferers of rheumatoid arthritis and asthma, according to three research studies published in the New England Journal of Medicine.
(A) significantly reduce the risk of heart attacks and also aid for
(B) be significant in reducing the risk of heart attacks and aid for
(C) significantly reduce the risk of heart attacks and aid
(D) cause a significant reduction in the risk of heart attacks and aid to
(E) significantly reduce the risk of heart attacks as well as aiding
Choices A, B, and D each produce a clearly unintended meaning: by using aid as a noun rather than a verb, each creates a misleading parallel with the noun risk so that the sentences nonsensically state that eating saltwater fish may reduce aid as well as risk. In addition, B and D are wordy and awkward. Choice C, the best answer, avoids the prepositions/or (from A and B) and to (from D), instead using aid as a verb that is parallel with reduce. Choice E lacks the grammatical parallelism of may reduce... and aid, the compound verb in C.
reduce和aid应该是同时发生的动作，如解释所说，是compound verb。这个时候只能用and，as well as暗示了aid发生在reduce之前，或暗示aid不如reduce重要，都不对。结合miaoyin提供的and用法，可以体会到compoud verb的感觉了。OG好几个地方解释说到compound，今天算是有了新体会。
