[解析]
I am writing to ask for whether you are able to do me a favor.I want to have an English pen friend,hopeful a girl in her early twenty,and with hobbies similar to mine.In my mind,she is someone interesting in travelling,swimming,and playing table tennis.Beside,it is better for her to have a pet dog as I have been keeping that at home for some time.I hope I can share∧ her my experiences in travelling,taking care of pets,or whichever we have in common.I believe I would improve my English by doing so and learn more about her country.I am looking forward to hear from you soon.
1.去掉for 考查介词.动词ask的后面可以直接加宾语从句,介词for是多余的.动词短语ask for后面通常接sth做宾语.
2.hopeful改为hopefully 考查副词.修饰句子要用副词.句意为:我希望能够交一个20多岁的英国笔友.
3.twenty改为twenties 考查固定搭配.在某人二十岁,应是in one's+twenties
4.interesting改为interested 考查形容词.be interested in…意为"…对…感兴趣",是固定搭配,使用interested in traveling修饰前面的代词someone.
5.Beside﹣Besides 考查副词.本句中表示"此外,而且".Beside是介词,意思是"在…旁边".
6.that改为one 考查代词.that指代同类异物时表示特指,而表示同类异物泛指时用代词one.
7.share后加with 考查介词.share with意为"与…分享[合用]",是固定搭配.句意为:我希望能够和她一起分享我的旅行经历.
8.Whichever﹣whatever 考查名词性从句.从句中缺少have的宾语,所以用连接代词,whichever表示有选择的含义,而句中表示无论什么,没有选择意思,所以用whatever.
9.would﹣will 考查时态.根据句意:我相信我这样做一定会提高我的英语,应该表示以后会有进步,故使用一般将来时,故would改为will.
10.hear﹣hearing 考查固定短语.本句中考查固定短语搭配.look forward to doing sth 盼望着做某事..故hear改为hearing.
