这10种雅思写作逻辑错误千万要避免

逻辑混乱是中国雅思考生写作的一大弊病，很多考生在雅思写作考试中，往往会想到哪儿写到哪儿，导致整个文章结构松散，还会常犯一些低级的逻辑错误。小编整理了10种容易导致丢分的雅思写作逻辑错误，考生们千万要引以为戒哦！

雅思写作逻辑错误1.草率前提 (Dicto Simpliciter)
　　例如：Women are on average not as strong as men and less able to perform well politically. Therefore, women can't pull their weight in government work.
　　点评：虽然女性确实在政界担任较少工作，但这不意味着女性群体中所有的人都是这样。

雅思写作逻辑错误2.过度概化 (Hasty Generalization)
　　例如：McDonald's and KFC offer foods with little nutrition, and thus we cannot expect any fast food restaurant to provide us with nutritious foods.
　　点评：两个个例不足以推出一个真理。

雅思写作逻辑错误3.因果颠倒 (Post Hoc)
　　例如：Most young criminals watch violent movies before they commit their crimes; obviously, violent movies lead to juvenile delinquency.
　　点评：甲事情发生在乙事情之前，这并不代表着先发生的甲事情就是后发生的乙事情的原因。

雅思写作逻辑错误4.矛盾前提 (Contradictory Premises)
　　例如：If God can do everything, can he make a stone so heavy that he can't carry?
　　点评：前提条件中就有相互矛盾的地方，结论当然是错误的。

雅思写作逻辑错误5.感性论证 (Ad Misericordiam)
　　例如：Think of all the poor, starving African children! How could rich countries be so cruel as not to help them?
　　点评：抒情是不能当作论证的。

雅思写作逻辑错误6.错误类比 (False Analogy)
　　例如：Young children are like flowers---flowers should stay away from terrible weather to grow, so children need to get rid of everything negative.
　　点评：孩子和花朵的区别太大。成长的过程也太复杂。最好不要用这两者来类比。

雅思写作逻辑错误7.虚假假设 (Hypothesis Contrary to Fact)
　　例如：If TV were not invented, today people would never have such wonderful entertainment brought by TV.
　　点评：因为电视已经被发明了，对于过去的否定假设后所得出的结论都是逻辑上的错误结论。

雅思写作逻辑错误8.无关转移 (Red Herring)
　　例如：Many people say we need to exploit the outer space, a point which I believe is wrong, because there are so many poor people on Earth who hardly make ends meet.
　　点评：有一个问题没解决并不代表着另一个问题不值得解决。

雅思写作逻辑错误9.从众错误 (Bandwagon)
　　例如：Everyone says it is justified to learn a second language so we must learn one.
　　点评：人人都说，或者大多数都说，这并不意味着该观点正确。

雅思写作逻辑错误10.滑坡谬误 (Slippery slope)
　　例如：If we don't care about the environment, the world will die in 50 years.
　　点评：从环境问题到世界灭亡，中间有无数环节未提供论证。
