Answer 1

Once there was a rich man whom got a serious eye disease．Afraid of go blind，he got a famous doctor to treat his eyes．The doctor advised himself to avoid bright light for a month．As soon as the doctor left，the rich man closed all his windows but replaced all the bright and colorful curtains in dark-colored ones．One month late，the doctor paid a visit∧his patient to check on his recovery．To the doctor's surprise，everything in the house were dark and dull．Then he said to the man，"In the fact，you could have bought a pair of sunglass instead of spending so much money making everything darker．"
解析：
1．whom-who．考查关系词．whom引导定语从句，做从句的宾语；who引导定语从句，做从句的主语．从句 got a serious eye disease缺少主语，所以用who．   
2．go-going．考查非谓语动词．介词of的宾语用doing，所以 go改为going．      
3．himself-him．考查代词．在The doctor advised himself to avoid bright light for a month句子里医生建议富人，所以用him代指富人．
4．but-and．考查连词．the rich man closed all his windows 表示"富人关闭了所有的窗户"；replaced all the bright and colorful curtains in dark-colored ones．表示"把明亮的，彩色的窗帘换成黑色的"，所以二者之间是并列关系，所以用and连接．   
5．in-with．考查介词．replace…with表示"用…替代…"，本句表示"把明亮的，彩色的窗帘换成黑色的"．
6．late-later．考查形似但语义不同的词．late表示"迟到，晚了"；later表示"以后"，本句One month late应该表示"一个月以后"，所以用later．         
7．visit后加to．考查固定短语．pay a visit to 表示"拜访某人"．    
8．were-was．考查主谓一致．和主语everything in the house 一致用was．   
9．the去掉．考查冠词．固定短语In  fact表示"实际上"．
10．sunglass-sunglasses．考查名词．眼镜有两个镜片，所以用复数sunglasses．
