    【答案解析】
    1. 將come改為been。come是終止性動詞，不與時間段連用。
    2. 將ask改為asking?，F(xiàn)在分詞作伴隨狀語。
    3. 在when前加and。 when引導(dǎo)的從句與how long引導(dǎo)的從句是兩個并列的賓語從句(作asking的賓語)。
    4. 將of改為to。在answer, key, way, entrance等名詞后，習慣上用介詞to。
    5. 在return前加will。這是將來時。注意：不要誤以為when引導(dǎo)的是時間狀語從句，用一般現(xiàn)在時代替將來時。事實上，when引導(dǎo)的是賓語從句。
    6. 去掉back或?qū)eturn改為go。因為return=go back。
    7. 此行正確。
    8. 將travel改為traveling。因為traveling與meeting并列，作enjoy的賓語。
    9. 將interested改為interesting。表示某事物“令人……的”用-ing形容詞;-ed形容詞則表示某人“感到……的”。
    10. 將it改為them。因為此處是指many things。
