[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。

[单选题]The passage suggests that the early shops for making tools were ______.

正确答案 ：A

not very sophisticated

解析：解析：本题的依据句是“At first，these articles were whittled with a knife，but when pioneer craftsmen set up their primitive shops most of them were fashioned on a lathe--a machine which holds an object and rotates it while it is being shaped by a tool.”在这里，A选项的not very sophisticated 意思为“并不复杂，是简单的”，对应原文中的primitive(原始的，简单的)。其他选项的内容属于无关信息。

[单选题]According to the passage, the first settlers used wood for their utensils and tools because it was ______.

正确答案 ：C

available

解析：解析：注意题干上的信号词utensils and tools，以此为目标可以很容易地找到本题的依据句“Because of the lack of other materials，early settlers were forced to make tools and utensils out of wood.”选择C的原因在于当时十分缺乏其他材料而木材到处都有所以得到采用。available意思为“有，存在”。

[单选题]What is this report mainly about?

正确答案 ：A

Phone inquires about hotel bookings for the 2008 Olympic Games.

解析：解析：这是一个典型的大意理解题，其依据句就是文章的主题句，一般位于文章的开头。本文的主题句就是第一个句子“Beijing's top hotels are fielding scores of calls from foreigners and Chinese people eager to book rooms during the 2008 Olympic Games in the Chinese capital.”与A选项内容相符和。其他的选项内容并不是本文的主题，而只是细节信息或无关信息。

[单选题]Which of the following statement is TRUE according to this passage?

正确答案 ：D

Not only foreigners but also native people wanted to book rooms for Games.

解析：解析：A和B选项与事实不符，属于错误答案；C选项也被否定，原因是文中说北京饭店并不接受提前这么长时间的预订，而只是记下预订人的姓名。D选项可以在文章中找到出处：“... the hotel had already received 50 to 60 such phone calls from would-be game-goers gambling on the result．Domestic callers have mainly come from the southern provinces of Guangdong and Fujian.”
