［誤］ there is a "f" in the word "football".
［正］ there is an "f" in the word "football".
［析］ 英文字母單獨使用時，如其第一個發音是元音時，其前面的不定冠詞應該用an而不是a.

［析］ be able to 主要表達某事或某人具有某種能力去作某事，應譯為"有本領"、"有能力"、"可以"作某事，如：i'm able to swim across this river. 而can可以用來表示具有接受能力或吸收能力。如：this radio can be repaired here.
about
［誤］ this class is about to begin just now.
［正］ this class is about to begin.
［析］ 要注意be about to 是"將要"的意思，含有將來時之意，不要與表示過去時的時間狀語連用。另外，be about to 一般用作書面語，對應的口語是be going to.
about on
about與on都可以作"關于"講，但卻有所不同，例如：this book is about physics. 應譯為"這是一本關于物理學的科普讀物。"而：this book is on physics.則應譯為"這是一本物理學方面的專著。"
above
［誤］ the temperature is five degrees over zero.
［正］ the temperature is five degrees above zero.

［誤］ there is often thick cloud above the south of china in summer.
［正］ there is often thick cloud over the south of china in summer.
［析］ 當表達覆蓋之意時，只可用over而不能用above.
［誤］ there is a bridge above the river.
［正］ there is a bridge over the river.
［析］ 用來表達"從……上方越過"時不能用above只能用over，如：the plane flew over the city. 但要注意there is waterfall above the bridge. 則應譯為"在橋的上游有一個瀑布。"
across

［正］ he ran through the wood.
［析］ across是指某一動作在一平面內進行，而through則是指該動作在一三維立體空間的運動過程。如：the man came in through the window. he walked across the square.
across
across的主要用法有兩個。其一，意為"對面"，如：there is a school just across the street. 其二，意為"橫過"，如：he walked across the street.
