Dear Amy，

　　I'm excited that you will come to visit China during the winter vacations．I'm writing to know that whether you can buy something for me．

　　Now，I'm wondering whether you can buy a kindle，∧e-book reader，for me，for the screen of my old kindle was broken because of the tore cover．It is produced by Amazon．I preferred a white one．Besides，the screen measure 19cm at 13.5cm will be better．By the way，my budget is about 1000yuan．Please help me to buy it if it is convenience for you．I will high appreciate your kindness．

　　I'm looking forward to your coming soon．

　　详

　　1．vacations改为vacation考查名词．the winter vacation指即将到来的寒假，不用复数．

　　2．去掉that考查连词．根据句意：我写信给你想知道你是否给为我买点东西．已有连词whether，that是多余的，要去掉．

　　3．加an考查冠词．reader是可数名词，单数形式前加不定冠词a表示泛指，因e-book的读音是以发元音开头的，用不定冠词an．

　　4．tore改为torn考查过去分词．要用过去分词作定语，tore是tear的过去式．

　　5．preferred改为prefer考查动词时态．全文讲述的是一般事实，用一般现在时态．

　　6．measure改为measuring考查动名词．分析句子结构，句中缺少主语，用动名词复合结构作主语．

　　7．at改为by考查介词．在英语中，长和宽之比用介词by．

　　8．it改为one考查代词．one指同类异物，it指同类同物，此处应是前者之意．

　　9．convenience改为convenient考查形容词．is后用形容词作表语．

　　10．high改为highly考查副词．appreciate是动词，用副词修饰．
