so do I和so l do分别的用法?

so do I我也一样,是个表肯定的倒装句,结构是：so +助动词+主语.助动词随上文句型变化.如：He likes English,so do I./I am tall,so is he./He can speak English,so can I.so l do我的确如此.是对对方所说或上文提及的事的肯定认可,句型结构是：so +主语+助动词.主语往往是同一个人或事.如：He likes English,so he does./He is clever,so he is./He has been to Beijing,so he has.

第一个：我也是这么认为的。第二个：我也是（这么做的）
