看答案
unnecessary
be completely 後需要形容詞,unnecessary 符合結構及「收件人都已有檔案」的語意。unnecessarily 是副詞,缺少可修飾的形容詞;necessitate 是動詞,不能直接接在 be 後;necessities 是複數名詞,不能在此由 completely 修飾。
同義改寫
Printing extra copies is unnecessary because everyone can access the shared file. → There is no need to print extra copies because everyone can access the shared file.
is unnecessary 與 there is no need to 都表示這個情境下不需要額外列印。
The team removed an unnecessary step from the booking process. → The team removed a step that was not needed from the booking process.
that was not needed 完整表達 unnecessary 在此處「不必要的」之意。
