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can
