    【答案解析】
    1. 把invite改為inviting?，F在分詞作定語修飾offer。
    2. 此行正確。
    3. 把five-weeks改為five-week。“數詞+連字符號+名詞”作定語，其中的名詞要用單數。
    4. 把allows改為allow。在助動詞will, would及情態(tài)動詞can, may, must等后面，永遠要用動詞原形。
    5. 把learned改為learning。while learning=while I’m learning。
    6. 在language前加the。特指英語這種語言。
    7. 把In改為Of。subjects“科目”，English是其中一個“科目”，表示級的比較范圍，若是整體與個別的關系，就用of。指時間、地點范圍，才用in。
    8. 去掉me。主語希望自己做某事，直接用hope to do sth，事實上，也不能用hope sb to do sth這一句型。
    9. 去掉level。這是中文式英語。improve=make…better。
    10. 把possibly改為possible。as…as possible(盡……)是習語。
