Logical Fallacies 常見邏輯錯誤
Logical Argument 如何構建一個有邏輯的論證
Task Response
/ 7分標準 /
1. 回應題干的每個部分的內容
2. 展現(xiàn)清晰的個人立場
3. 提出、引申并論證主要觀點（但可能有過度概括，分支觀點不夠緊湊）
Logical Fallacies
/ 常見邏輯錯誤 /
① 草率結尾：證據(jù)太少
After being New York for a week, I can tell you all New Yorkers are rude. →為什么來了紐約后發(fā)現(xiàn)紐約人是rude呢？
② 循環(huán)論證：重復論證
She is ignorant because she was never educated. →ignorant和never educated意思重復
③ 不當結論：前后兩句話沒有邏輯聯(lián)系
My teacher is handsome, I will learn a lot from him. →handsome和learn a lot之間沒有關系
/ 論點結構 /
一般一篇論文論點需要三部分組成：
Premise 前提
Conclusion 結論
Inference 論證/推導過程
舉個栗子：
說起人口老齡化帶來的負面影響，同學們往往會如此推導
老年人比例上升=年輕人比例下降=社會勞動力總數(shù)減少=經濟下滑
但事實上，勞動力總數(shù)和經濟沒有直接關系
正確的推導思路應是：
人口老齡化帶來的負面影響：老年人比例上升=年輕人比例下降=社會勞動力總數(shù)減少=勞動力供給減少=所發(fā)工資減少=所交稅收減少=經濟下滑
Logical Argument
/ Deductive Arguments /
Deductive Arguments 即演繹式推論
結論往往跟在前提后，如果所有前提都為真，則結論一定為真
在這其中，最著名的就是三段論(Syllogisms)了
All B are C. All A are B. 推導出→ All A are C
e.g. All humans have hearts. All lawyers are human.
→(therefore) All lawyers have hearts.
All mammals are animals. All cats are mammals.
→(therefore) All cats are animals.
下面的例子告訴我們，如何利用上面這個邏輯來論證雅思作文~
/ 例題 /
Some people think that the best way to protect environment is to increase the price of the fuel of the cars are other vehicles. To what extent do you agree or disagree?
【disagree】
The rationale to increase the price 增加燃料價格的合理性
1. Using less private vehicles 減少私家車數(shù)量
The reduction of carbon dioxide emission (B) can protect the environment (C)
Using less private vehicles (A) can reduce the emission of carbon dioxide (B)
→Therefore,
Using less private vehicles (A) can protect the environment (C)
Example answer:
Raising the price of fuel, government could deter people from using private vehicles. For example, if the price of petrol went up, people would start to take public transports instead of driving their cars, resulting in the reduction of carbon dioxide emission which is responsible for global warming and climate change.
??這里注意deter和prevent區(qū)別，deter-震懾、威脅，強調行為；prevent-阻止，強調主語
2. Reducing the exploitation on natural resources
人們需求減少=商家產量減少=自然資源開發(fā)減少=保護環(huán)境
