15、school” , but in the second sentence the subject is “we” .T:Very good. When we are using Participles, we should pay attention to the subjects in the sentences, and the Participle we use must have the same logical subject as the subject in the sentence. If the subject in the sentence receives the act

16、ion, we should use the Past Participle as Adverbial;if the subject in the sentence does the action, we should use the Present Participle as Adverbial. Is that clear?Ss: Yes.Step VII PracticeT:0K.
