七、书面表达。
假设你是Susan，最近你为下面提示中的事感到苦恼。请你写一封信向你的好朋友Jack寻求建议。
【提示】我有一个很好的朋友Linda，她以前是一个刻苦用功的女孩。可最近她变了，她花很多时间打游戏、逛街，成绩也一落千丈。上周末她还以买书为借口向父母要零花钱，可实际上她一本书都没买，全都用来买衣服了。我劝过她，可她不听，还说如果我将此事告诉她父母，我就不是她的朋友。
【要求】1. 条理清楚，意思连贯，语句通顺，标点正确。
2. 80个单词左右，开头和结尾已给出，不计入总词数。可适当发挥，以使行文连贯。
Dear Jack,
I am writing to you for advice about my good friend Linda.

       Linda was once a hard-working girl. But recently, she has changed a lot. She doesn't work hard 
; any more. Instead, she spends a lot of time and money on games and clothes. She failed the tests many
; times. Last weekend, she even cheated her parents. She asked her parents for money to buy books
; but she spent all of the money on some fashionable clothes. I talked with her but she said it was none of my business. And she said that if I told her parents about that, she wouldn't be my friend any longer. What should I do?
