复合句中的not only but also

Question

I bought the book because not only it is beautiful but also I need it
第一 为啥后面的那个not only 后不用倒装
第二 because 能 放在 not only 后面吗
He can not only do it but also do it well
can 为什么要放在前面

还有一个就是在英语中几个句子并列放在一起时。。关于省略引导词 （什么时候能省什么时候不能省）麻烦大家给说一下

Answer 1

1.not only, but also 是固定句型 不但。。而且，跟陈述语序即可
2.如果because放在 not only 之后，完整的句子应该是I bought the book not only because it is beautiful,but also because I need it.
3.can 可以放在后面，完整句型是 He not only can do it, but also can do it well.
需要注意，not only... but also... 后面跟的句子要句型一致
如：not only+短语，but also+短语
not only+句子， but also+句子

Answer 2

1.because后面的 not only it is beautiful but also I need it 是个宾语从句，用陈述句序不用倒装
2..because后也是个宾语从句，只不过在这句中都省略了引导词that。你没分清
3.He can not only do it but also do it well
本句中.He 是主语， can 是谓语not only do it but also do it well
还是一个宾语从句
4.在英语中几个句子并列放在一起时，当从句是宾语从句时，引导词（标准的说法是先行词）可 以省，当从句是定语从句时，必须有引导词（我见过的所有题都是这样的）不可省略
