同学们都知道非谓语动词在句中不能作谓语,因而无语法上的主语,但非谓语动词具有动词的特征(即表示一个动作),所以它们可以有意义上的逻辑主语(即这个主语在逻辑上是非谓语动词所表示的动作的执行者或承受者)。况且我们在实际使用非谓语动词时,往往需要考虑其逻辑主语 The classmates all know that non-predicate verbs cannot be predicated in sentences and therefore have no grammatical subject, but non-predicate verbs have verbs (ie represent an action), so they can make sense to the logical subject (ie the subject is Logically is the executor or receiver of the action represented by a non-predicate verb.) Moreover, when we actually use non-predicate verbs, we often need to consider its logical subject.
