常見錯誤

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

×The weather is very variable today.

The weather is very changeable today.

雖然 'variable' 和 'changeable' 都有「易變的」意思,但 'variable' 通常描述在一個範圍內或一段時間內的變化性,而不是描述單一時間點的狀態。描述天氣在一天內的變化,用 'changeable' 更自然。

×We offer variable payment options.

We offer various payment options.

'Variable' 強調的是「會變化的、不固定的」,而 'various' 指的是「多種不同的、多樣的」。支付選項是「多種不同的」,而不是「會變化的」,因此應使用 'various'。

×The results were variable from the experiment.

The results of the experiment were variable.

在英文中,形容詞 'variable' 通常直接修飾主詞,或放在 be 動詞之後作為補語。不應使用 'variable from...' 這樣的結構來表示來源。

×People have variable opinions on this topic.

People have different opinions on this topic.

'Variable' 描述的是同一事物本身具有變化性或不穩定性。而描述多個人持有「不同的」意見,應該使用 'different'。'Variable opinions' 會讓人誤解為同一個人的意見反覆無常。

×The data is very variable, so we can't draw a conclusion.

The data is highly variable, so we can't draw a conclusion.

雖然口語中可能聽到 'very variable',但在正式或學術寫作中,形容變化程度「很大」時,更常使用 'highly variable'、'extremely variable' 或 'shows high variability'。
