常見錯誤
What are common mistakes with "Common"?Which "Common" sentences look correct but are wrong?
×It is common that people think so.
✓It is common for people to think so.
當主詞是虛主詞 'it' 時，正確句型是 'It is common for someone to do something'，而不是 'It is common that...'。
×This is a very common sense.
✓This is common sense.
'common sense'（常識）是一個不可數的複合名詞，前面不加 'a'，也不能用 'very' 修飾。若要強調，可用 'basic/common sense' 或 'a matter of common sense'。
×He is a common friend with me and Tom.
✓He is a friend common to me and Tom.
表達「某人是我和 Tom 共同的朋友」時，形容詞 'common' 應放在名詞後，使用 'common to A and B' 的結構，或更自然地說 'He is a mutual friend of Tom and me.'。
×It's more common to use this method than that method.
✓It's more common to use this method than that one.
在比較結構中，為了避免重複 'method'，應使用 'that one' 或 'the other one' 來指代前面提到的單數可數名詞。
×This problem is very common in the world.
✓This problem is common worldwide. / This is a common problem around the world.
'in the world' 在此語境下聽起來不自然且範圍模糊。使用 'worldwide', 'around the world', 或 'globally' 更為地道。
×We have a common goal to win the game.
✓We share a common goal of winning the game.
雖然 'have a common goal' 文法正確，但 'share a common goal' 是更常見且地道的搭配。此外，表達目標內容時，常用 'of + V-ing' 或 'to + V'。
