学习非谓语动词时，不管是动词不定式、分词还是动名词，常见有逻辑主语的提法。什么是逻辑主语？它是相对于句子的语法主语而言的，是指在量谓语动词在语义上而不是语法意义上的动作的执行者或承受者。它可以是句子的主语也可以是其它成分。这样逻辑主语就不像句子的主语那样固定而一目了然。它的位置灵活多变，因此需要读者凭自己丰富的语法知识去判断和认别它。初学非谓语动词时，很容易错用逻辑主语。现列举一些常见的典型错误作为警示。
一、错用动词不定式的逻辑主语
1．To master English, spoken English must be practiced every day.
分析：“to master English”的逻辑主语不可能是句子主语spoken English, 而应该是人。故将错句改为：
To master English we must practice spoken English every day.
2．The emperor ordered the wonderful cloth weave as soon as possible.
分析：the wonderful cloth是动作weave的承受者而不是施动者，因此weave应该是被动式；又鉴于动作尚未进行，故使用不定式的被动式最为恰当。全句改为：
The emperor ordered the wonderful cloth to be woven as soon as possible.
值得注意的是，当将不定式作为插入语表示说话人的态度或看法时，它的逻辑主语往往游离于句子之外。在这种情况下再在句中找逻辑主语就没有意义，也不能说逻辑主语错了。常见的不定式作插入语的短语有：to be frank（坦率地说），bo be honest（老实地说），to tell you the truth(老实对你说)，to make things worse（更糟糕的是）。例如：
He had no money to buy the necessaries. To make things worse, an unknown disease was holding(困扰着) him, confining(限制) him on bed all the year round.
To venture to say, he is sure to lose the match.(我)可以斗胆地说，他肯定要输掉这场比赛。
To tell you the truth, the boss appreciates your talent very much.(我)老实告诉你吧，老板很赏识你的才能。
