BOTH與ALL的不同之處在于以下幾點(diǎn)：
前者和后者的漢語(yǔ)意思雖都為“都”,但BOTH用于“兩者都”,而ALL用于“三者都”
第二點(diǎn)：如果BOTH與AND 連接的話,既可連接可數(shù)名詞,也可連接不可數(shù)名詞.BOTH 和BOTH OF都加名詞
例如,THERE ARE MANY TREES ON BOTH SIDES OF THE ROAD；I LIKE WATER AND AIR,THEY ARE BOTH VERY IMPORTANT TO OUR LIVES.
BOTH放在系動(dòng)詞后,放在實(shí)意動(dòng)詞之前
ALL 既可修飾可數(shù)也可修飾不可數(shù)名詞.例如：
ALL THE APPLE ARE IN THE CAR；ALL OF THE WATER HAS BEEN DRUNK BY ME.
