Question

17．Do you know of anyone who uses the truth to deceive （欺骗）？When someone tells you something that is true，but leaves out important information that should be included，he can give you a false picture．
 For example，some might say，"I just won a hundred dollars on the lottery （彩票）．It was great．I took that dollar ticket back to the store and turned it in for one hundred dollars!"
This guy is a winner，right？Maybe，maybe not．We then discover that he bought  $200 worth of tickets，and only one was a winner．He's really a big loser!
He didn't say anything that was false，but he left out important information on purpose．That's called a half-truth．Half-truths are not technically lies，but they are just as dishonest．
Some politicians often use this trick．Let's say that during Governor Smith's last term，her state lost one million jobs and gained three million jobs．Then she seeks another term．One of her opponents says，"During Governor Smith's term，the state lost one million jobs!"That's true．However，an honest statement would have been，"During Governor Smith's term，the state had a net gain of two million jobs．"
Advertisers will sometimes use half-truths．It's against the law to make false statements，so they try to mislead you with the truth．An advertisement might say，"Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache．"It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company．
This kind of deception happens too often．It's a sad fact of life：Lies are lies，and sometimes the truth can lie as well．

A．buy lottery tickets if possible          
B．make use of half-truths
C．be careful about what they are told      
D．not trust the Yucky Company
30．How many examples does the writer give to show how the truth is used to deceive？

Answer 1

分析 本文讲了生活中的一种现象：用事实骗人．有的人只说出部分事实来欺骗别人，有的时候那也算是一种谎言．作者在文中举了几个例子来说明这一现象．

解答 29．C   推理判断题   根据"Lies are lies，and sometimes the truth can lie as well 谎言是谎言，但是有的时候事实也会说谎．"可知，我们对我们听到的东西要仔细辨别．故答案为C
30    C  细节理解题   根据"For example，someone might say""Some officers often use this trick""Advertisers will sometimes use half-truths"可知，文中举了三个例子．故答案为C
31    D  细节理解题  根据"It's against the law to make false statements so they try to mislead you with the truth"可知，用部分事实说谎并不违反法律，因为并不都是虚假信息，故A不正确；根据"sometimes the truth can lie as well"可知，事实只是有的时候会说谎，并不完全是谎言，故B不正确；根据"It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company"可知，这个做的是虚假广告，那个药不一定是好的，故C不正确；根据"her state lost one million jobs and gained three million jobs"可知，史密斯在任期间就业的净增长是200万个工作，故D正确．

点评 做阅读时经常犯错的主要原因是，仅凭读过文章后残留在脑海中的一丝印象来勾选答案，这样便很容易掉入出题人故意设布下的题目陷阱．所谓阅读理解，对于题目的理解一定要忠实于原文，因此，每一道题都应该与原文作全面的对比与核查，再得出答案．也就是说，阅读理解的每一道题目，在原文都应该有明确的出处，我们把这一出处叫做原文相关句，（1）排除与原文相关句主题不一致的选项（2）排除与原文相关句态度相反的选项 （3）排除用于过于极端或负面的选项（4）注意结合文章主旨和主题去排除．
