四選一
The office printer is so ____ that staff often use the one upstairs instead.
看答案
unreliable
此處使用 so＋形容詞＋that 子句，描述印表機不可靠的程度，因此選 unreliable。unreliably 是副詞，不能在此作為描述印表機的補語；unreliability 和 reliability 是名詞，不能直接填入本句的 so 後。
同義改寫
The office printer has become unreliable and often stops halfway through a print job. → The office printer can no longer be depended on and often stops halfway through a print job.
has become unreliable 表示設備已變得靠不住；can no longer be depended on 保留這項狀態變化與可靠性降低的意思。
The attendance figures are unreliable because several entries were counted twice. → The attendance figures cannot be trusted because several entries were counted twice.
此處 unreliable 指數據因重複計算而不足採信；cannot be trusted 保留對資料可信度的相同判斷。
