You do something apprehensively when you are worried or nervous about what is coming — a test, a visit to the dentist, a talk you have to give, news you have not heard yet. The feeling looks forward: the trouble is not here yet, but you can already feel it.

It is a fairly ordinary adverb in stories and everyday description, a little more formal than nervously.

It is a fairly ordinary adverb這是個相當常見的副詞 in stories and everyday description用在故事和日常描述裡 a little more formal than nervously比nervously稍微正式一點

Though actually, it is not comprehensively (that means “fully, covering everything”), and it is not about the police catching a thief — even though the verb apprehend can mean that. In real use, apprehensively almost always means “in a worried way.”

Though actually不過事實上 it is not comprehensively它不是comprehensively (that means "fully, covering everything")（意思是「全面地、涵蓋一切」） and it is not about the police catching a thief也跟警察抓小偷無關 even though the verb apprehend can mean that雖然動詞apprehend確實可以是那個意思 In real use在實際使用裡 apprehensively almost always means "in a worried way."apprehensively幾乎都是指「帶著擔心的心情」
