It not only can 还是 It can not only

It can not only.bust also
It not only can .but also can...
这两个都可以
我想写这个句子
How many passengers can it carry? Can it land anywhere or not? （not only.but）
前面是肯定回答（7个乘客） 后面也是肯定回答
上面两种形式都可以：具体如下
It can not only carry 7 passengers but also land anywhere.
It not only can carry 7 passengers but also can land anywhere.
如果can放在前面的话,not only 和but also 是共用一个can
如果不是的话,则not only和but also 分别使用一个谓语canHe not only can play the piano, but also can play the guitar.He can not only play the piano, but also play the guitar.He can play not only the piano, but also the guitar.那这样的话 这三种说法都对吗？这三句说法都是正确的，如果是共同使用一个谓语的话，可以放在前面，如果不是的话，就要分开。not only … but also 应连接两个相对称的并列成分。例如：　　I not only play tennis but also practise shooting. （连接两个谓语动词）　　He plays not only the piano but also the violin. （连接两个宾语）不共同使用一个谓语就要分开？不太明白什么意思，请详解I not only play tennis but also practise shooting. （连接两个谓语动词）以这句话为例子，play tennis 和practise shooting的谓语动词分别是play和practise，这个是时候play就不能放在前面，因为能说play tennis ，但是不能说play shooting　　He plays not only the piano but also the violin. （连接两个宾语）以这句话为例子，play piano 和play the violin的谓语动词都是play，这个是时候play就能放在前面，因为能说play tennis ，也能说play the violin
