Mrs. Wilson,
I’m going out shopping and won’t come back soon. I have taken with me the four book which you asked me return to the City Library. On about 1 o’clock this afternoon, your neighbor Tracy come to visit you. Looked worried, she said she couldn’t drink coffee with you this evening. She also said that her father were ill and that she would have to take care of him. She felt terrible sorry and promised to visit you before her father got better. By the way, she has already been told Susan and Grace about this change, so you needn’t call themselves.
Yours
Liu Mei
答案
【1】book→books
【2】me后面添加to
【3】On→At
【4】come→came
【5】Looked→Looking
【6】were→was
【7】terrible→terribly
【8】before→after
【9】been去掉
【10】themselves→them
解析
试题分析：
【1】book→books 考查名词单复数。根据前面“four”可知，这里有四本书，是复数，故改为books。
【2】me后面添加to 考查固定结构。ask ab. to do是固定结构，意为“要求某人去做某事”，故添加to。
【3】On→At 考查介词。在几点钟前面用at，是固定用法，故改为At。
【4】come→came 考查时态。根据全文可知，本文主要以一般过去时为基本时态，故改为came。
【5】Looked→Looking 考查非谓语动词。look和she之间构成主动关系，这里放在句首应该用现在分词作伴随状语，故改为Looking。
【6】were→was 考查be动词的用法。主语是her father，故be动词应用单数形式，故改为was。
【7】terrible→terribly 考查副词。修饰形容词要用副词，故把terrible改为terribly。
【8】before→after 考查介词。根据语境可知，是在他的爸爸变得好起来之后发生，故改为after。
【9】been去掉 考查语态。本句是主动语态，她已经告诉Susan和Grace这个变动了，故把been去掉
【10】themselves→them 考查宾语。动词call在句中不是谓语动词，非谓语动词后面用宾格，故改为them。
