Our school is only A 5-MINUTE walk from here.
==Our school is only 5 MINUTES' walk from here.
注意：
1 walk在這里做可數(shù)名詞單數(shù)用.A 5-MINUTE 在功能上與5 MINUTES' 一樣,都是做定語(yǔ)
2 注意比較：------（一份）5天的工作：
1 5 days' work （5 days' 已經(jīng)是定語(yǔ)了,work ----工作是不可數(shù)名詞,所以前面沒有a）
2 5-day work (work是不可數(shù)名詞,前面沒有a)
3 5 days' job (5 days' 已經(jīng)是定語(yǔ)了,所以前面沒有a)
4 a 5-day job (job是可數(shù)名詞單數(shù),前面必須有a)
