橫越=Across, Acrossed,
and Cross?
正確答案是......
(A) When Steve Vaught began walking cross the United States he had
     two simple, yet difficult goals.
(B) When Steve Vaught began walking across the United States he had
     two simple, yet difficult goals.
 你答對了嗎?

正解:

正確答案是(B)。Across是一個介係詞,用來表示兩個人、地點、或事情的關係,有時候會跟from一起出現。
Example: That house is across the street. 在…對面。

   
Cross通常是名詞或是動詞詞性。當作動詞,表示越過的意思;Cross當作名詞,表示十字型物品。

Crossed是動詞cross的過去式與過去分詞。
Examples:
Will you cross the street with me? (Verb) 穿過
Jesus, Peter, and Andrew each died on a cross. (Noun) 十字架
He crossed the street with me. (Past tense) 穿過
   
特別提醒同學注意:不要使用acrossed, crossed, or acrost這三個字當作介係詞或是副詞。acrosse or acrost這兩個字基本上只有少數時候用於方言中。
