18．I was coming downstairs to get breakfast when the post came．I was waiting for a letter from my friend Sam，so I picked the letter up and looked through them．I wasn't surprise to see that there were some bills．There was an invitation to a party．There wasn't a letter from Sam．（60）B，it shows some birds and the sea．What a nice picture!I turned the postcard over．It wasn't easy to read．（61）C．I didn't know who wrote it？I tried to read any of the words．I could read"Dear Tom，I'm having a lovely time in…．"Then the writing became unclear．（62）E．Who had gone to the seaside？I couldn't think of anyone!It was a mystery（谜团）．There was another mystery too．Where was Sam's letter？
Just then the phone rang．It was Sam!"I'm calling to see if you got any postcard，"he said．"We are at the seaside，not in London．We changed our minds．Mum and Dad are resting after our walk．（63）A．I'm sorry I didn't write a letter．We've been so busy．"
Both mysteries were solved!
A．So I'm ringing you
B．There was a postcard
C．Rain had made the writing unclear
D．There're many people here．
E．I couldn't read anything else．
分析 本文主要讲述了作者出门买早餐时，邮递员来了，作者一直在等朋友萨姆的来信，结果找了半天也没有找到萨姆的信，却收到了一封明信片．可是因为雨水，明信片上的单词看起来很模糊，所以作者不知道是谁寄来的．就在作者疑惑不解的时候，萨姆打电话告诉他他们一家人去了海边，因为太忙了没有给作者写信，而是寄了一封明信片．
解答 60．B．根据后文it shows some birds and the sea．What a nice picture!I turned the postcard over．可知作者收到了张漂亮的明信片，故选择B．
61．C．根据文中It wasn't easy to read…I didn't know who wrote it？可知这张明信片读起来很费劲，作者不知道这是谁写的，这些都是因为雨水明信片上单词变得很不清晰，故选择C．
62．E．根据文中I could read"Dear Tom，I'm having a lovely time in…．"Then the writing became unclear．可知作者只能看到明信片的部分单词，其他都看不清，故选择E．
63．A．根据文中可知萨姆打电话告诉作者他们一家人去了海边，因为太忙没有时间写信，而是寄了一张明信片，特地打电话告诉作者这件事，故选择A．

| Hi Mary， Thank you for writing to me and I will try to give you some ideas about improving your written English．The bad news，of course，is that there is no （92）easyway to do this．It takes work． Improving your English，like getting better at anything else，means lots of practice．I think you already know enough words and grammar in English to make sentences and to understand English，and the problem you have is as the problem all Chinese students have when they learn English．You go to English class a couple of times a week and the（93）restof the time you speak Chinese．If you come to Canada，your English would improve very （94）quicklybecause you would use it all day，every day．It's just practice． To improve your writing in English，you should do （95）twothings．First，you should try to read English as much as possible．It doesn't matter what you read，so pick something that interests you．Reading English will show you how English words are used together，how English speakers express themselves and so on，so you can learn a lot from that．Then you should practice writing．Ask your teacher if you can get extra assignments and write things like short stories．Your teacher can show you where you make mistakes and how to （96）correctthem．You can also write more letters to English speakers on the Internet （I will be happy to exchange letters with you if that will help）．Don't worry if you make mistakes （97）because that is how you learn．You say you can not obey your plans．In English we say，"Plan the work，work the plan．"You need a plan and then you need to follow your plan to improve．I hope these ideas are （98）useful．I wish you luck，and if you want to write to me I will be happy to try to help you．We can talk about China，about Canada or anything else you like． Best wishes，Brad Flankin |
