Not Given
1.题目在原文中找不到依据。
切记不能光凭自己的知识理解来判断，即使出现题目中说“地球是方的”.
2. 题目的范围比原文的范围小。(如果反过来，就是T)
举例：
原文：Tea is good for peoples’ health.
题目：People can get benefits from Green Tea.
3. 题目中有比较结构，原文中无比较结构。
举例：
原文：And the future? It is anticipated that, in the years to come, leisure facilities spending will account for between a third and a half of all household spending. Whilst it is difficult to give exact figures, the leisure industry will certainly experience a long period of sustained growth.
题目：In future, people will pay less for the leisure facilities they use than they do today.
定位词：leisure facilities
考点词：less
4. 题目中有表示趋势的词或词组，而原文却无法找到相关的表达。
举例：
原文：The future, we are told, is likely to be different. Detailed surveys of social and economic trends in the European Community show that Europe’s population is falling and getting older. The birth rate in the Community is now only three-quarters of the level needed to ensure replacement of the existing population. By the year 2020, it is predicted that more than one in four Europeans will be aged 60 or more and barely one in five will be under 20. In a five-year period between 1983 and 1988 the Community’s female workforce grew by almost six million. As a result, 51% of all women aged 14 to 64 are now economically active in the labor market compared with 78% of men.
题目：The rise in the female workforce in the European Community is a positive trend.
定位词：European Community female workforce(专有名词)
考点词：positive
这道题引出：如果原文没有提到，也只能是NG。或者，题目中表示现在情况，而原文表示将来或者过去，也是NG，反之亦然。
5.主体动作发生的时间段不一样，导致信息无法判断。
举例：
原文：Since the early years of the twentieth century, when the International Athletic Federation began keeping records, there has been a steady improvement in how fast athletes run, how high they jump…
题目：There was little improvement in athletic performance before the twentieth century.
定位词：年代twentieth century
考点词：little，before
6. 题目中句子的主语或宾语和原文中的主语和宾语进行了“偷天换日”， 因此无法判断，为NG。
举例：
原文：In the last 20 years, scientists have detected an increasing variety of toxic contaminants in the North, including pesticides from agriculture, chemicals and heavy metals from industry. These are substances that have invaded ecosystems virtually worldwide, but they are especially worrisome in the Arctic.
题目：Industry in the Arctic has increased over the last 20 years.
定位词：Arctic，20 years
考点词：increased
对于Y/N/NG这类题目，还有1项黄金法则，不妨在时间紧急又太纠结的时候用起来：
题目中若出现must，only，all，most及always等极端绝对化的词语，答案是80%是F，20%是NG。
举例：
原文：Hydroelectric power is at present the earth’s chief renewable electricity source, generating 6% of global energy and about 15% of worldwide electricity. Hydroelectric power in Canada is plentiful and provides 60% of their electrical requirements. Usually regarded as an inexpensive and clean source of electricity, most big hydroelectric projects being planned today are facing a great deal of hostility from environmental groups and local people.
题目：Canada uses the most hydroelectric power in the world today.
定位词：Canada ，hydroelectric power
考点词：most
