常見錯誤

What are common mistakes with "Baseline"?Which "Baseline" sentences look correct but are wrong?

×We need to set a baseline for the project to start.

We need to establish a baseline before the project starts.

「set a baseline」語法上沒錯,但「establish a baseline」是更常見、更專業的搭配,特別在專案管理或科學領域中。

×His score is the baseline of the class.

His score is below the class baseline. / His score serves as the baseline for the class.

「baseline」指的是用來比較的標準或起點,不是一個比較級(如最高或最低)。要表達「低於基準」或「作為基準」才正確。

×We compared the new data with the baseline.

We compared the new data against the baseline. / We compared the new data to the baseline.

雖然「compare with」可用,但在與一個既定標準(baseline)進行對比時,「compare against」或「compare to」是更精準、更常見的用法。

×The baseline is very high.

The baseline is set very high. / The baseline level is very high.

「Baseline」本身是一個抽象概念(標準、起點),通常不會直接用「high/low」形容其本身,而是形容「baseline level」或說明它是被「set」在某個高度。

×This is our baseline plan.

This is our baseline. / This plan serves as our baseline.

「Baseline」本身已包含「作為比較基礎的標準方案或數據」之意,加上「plan」顯得多餘且不自然。應直接使用「baseline」或換個說法。
