    【答案解析】
    1. all改為both。指Mary和作者兩個(gè)人。
    2. when改為and或while。因?yàn)閮蓚€(gè)分句沒(méi)有主從關(guān)系。而是并列關(guān)系，或者有對(duì)比或?qū)φ盏暮x。
    3. look改為see。因?yàn)榇司湟鉃椤皟蓚€(gè)人不能經(jīng)常見(jiàn)面(see)”。
    4. 去掉keep或把we’re改為we。因?yàn)閗eep是動(dòng)詞，若不是進(jìn)行時(shí)態(tài)或被動(dòng)語(yǔ)態(tài)，動(dòng)詞前不用be，但句中沒(méi)有動(dòng)詞時(shí)必用be。所以去掉keep或去掉are，
    5. telling改為tell。tell和write是并列謂語(yǔ)。
    6. happened改為happening。因?yàn)檫@是現(xiàn)在進(jìn)行時(shí)態(tài)。
    7. phone前加the。因?yàn)閛n the phone是習(xí)語(yǔ)，意為“用電話(交談)”。
    8. Sometime改為Sometimes。此處表示“有時(shí)候”，而不是表示“某個(gè)不定的時(shí)候”。
    9. 此行正確。
    10. luck改為lucky。用形容詞作表語(yǔ)。
