四選一
The manager reminded the team that the draft report must remain ____ until Friday.
看答案
confidential
remain 在此是連綴動詞，需要形容詞 confidential 描述報告持續處於保密狀態。confidentiality 是抽象名詞，不能在此表示報告的狀態；confide 是動詞；confidentially 是副詞，不能補足此處所需的狀態描述。
同義改寫
The project manager stored the confidential draft in a folder accessible only to the project team. → The project manager stored the draft intended to be kept private in a folder accessible only to the project team.
intended to be kept private 保留 confidential 所表達的保密意圖；兩句都描述同一份草稿與相同的存取限制。
During our break, my colleague spoke in a confidential tone about her hopes for a new role. → During our break, my colleague spoke in a tone of close personal trust about her hopes for a new role.
此處 confidential 描述推心置腹的語氣；a tone of close personal trust 保留親近與信任的含意。
