這個(gè)問(wèn)題屬于非謂語(yǔ)動(dòng)詞的用法。非謂語(yǔ)動(dòng)詞主要是三種形式：第一，動(dòng)詞不定式即to do形式，表達(dá)要做的事，比如To go a college is my dream.再比如We need to find a place to eat something;第二是動(dòng)名詞即v-ing形式，表達(dá)正在進(jìn)行或伴隨性狀態(tài)卻不是進(jìn)行時(shí)態(tài)，因?yàn)檫M(jìn)行時(shí)態(tài)動(dòng)名詞前要加be動(dòng)詞.比如He went to bed listening to the music last night.再比如She sat in the classroom lisenting to the teacher;第三是過(guò)去分詞作定語(yǔ)，表達(dá)被動(dòng)的意思，卻不是被動(dòng)語(yǔ)態(tài)，因?yàn)楸粍?dòng)語(yǔ)態(tài)的過(guò)去分詞前要加be動(dòng)詞，比如a boy called Tom,一個(gè)被叫做湯姆的男孩，a book written by Luxun一本被魯迅寫的書(shū)。
