[单选题]Mrs. White is different from her friends who were ______.

正确答案 ：B

not always hopeful

解析：解析：本题题干上的信号词为different和friends，依据句为“Unlike her friends， however，she never lost heart.”其中lose heart =lose hope。此句意为“她从来都是满怀希望，而她的朋友与她不同，并不是经常满怀希望”。

[单选题]I don't know his address, ______.

正确答案 ：B

otherwise I would write to him

解析：解析：在otherwise或or引导的并列分句中用虚拟语气。此时，otherwise或or引导的并列句相当于非真实性条件句中的主语部分，前一分句暗示了现在的情况，因而在 otherwise引导的分句中要用与现在事实相反的虚拟语气。

[单选题]Guest: Oh, I hadn't realized how late it was. I'm afraid I'll have to be going. Host: Oh, not yet. I'm just going to make some coffee. Guest: ______ , though I'd really love to stay. I've got to be up by six tomorrow morning, unfortunately. Thank you for a wonderful party.

正确答案 ：A

I'm sorry, but I must

解析：解析：主人诚心挽留，客人坚持要走。由于不能接受主人的好意，客人应表示歉意，故而选择A．I'm sorry，but I must比较合理。其他选项使用场合不当。

[单选题]Mrs. White's husband tried to ______.

正确答案 ：C

stop her from buying unnecessary things

解析：解析：注意题干上的名词：Her husband在文章中出现的地方，从而可以很容易地找到本题地依据句“Her husband tried again and again to persuade her to give it up，but she just wouldn't listen.”本句话的主要意思为丈夫不让她为了中奖而购买不必要的东西，并不是不让她去商场。所以B选项错误；A和D选项内容在文中没有出现，属于无关信息。
