武漢ACT培訓班如何選擇？因果論證是比較常見也是ACT大多數同學使用較多的論證方法，但是通常情況下寫出的因果論證并不深入。因為原因有時是多層的，有些現象看起來似乎是發生作用的原因，但在它們的背后，卻還有產生它們的原因。對于多重原因的事物，如果只停留在其中的某個層面上，把它當成較終因素，論點就可能不深刻，也難以把問題說透。這樣的因果論證，其說服力是有限的。

新航道以構建中國完美社會英語教育體系為目標，以“我堅持，我成功”為精神內涵，提出并堅持“創新、學術、勵志、激情”的教育理念，憑借著深厚的學術功底、務實的教學作風、強勁的研發能力和旺盛的進取精神迅速在行業當中脫穎而出，從教學內容、教材研發、授課質量、環境服務等多個方面創立了全新的標準，從而引領中國英語培訓業全面升級，為廣大中國學生創建英語成功之道。

遇到這種情況，應當一層一層地追究下去，一直到找出較終極的原因為止。一般來說，越是表層的原因，越是為大家所熟知的，其論證力也就越有限;越深層的原因，就越能說明問題的實質，就越有說服力。

以舊版本范文Intelligent Machines里面的一段話為例。

The replacement of humans by machines leads to the loss of value to human life, an effect that outweighs the material gains of automation. The search to find human tasks that can be performed by machines inevitably leads to comparisons between the human and the machine. If a company executive wants to see if a inventory management team can be replaced by a robotic system, he will compare the two and determine which can do a better job. When this occurs, the people on the team are evaluated not for their worth as human beings, but for their effectiveness at performing a specific function—in essence, as we would evaluate a machine. In a larger sense, when we begin to think about humans in this way, the worth of a person’s life becomes dependent on only what they can do and no longer has any intrinsic value. As Perspective One states, we begin to lose our humanity. This new mindset and way of evaluating people, though seemingly harmless in the workplace, is devastating when it begins to pervade a society. If a person is judged only on his or her capability, there is no reason for a person to remain after they have served their function. This would warrant genocide against the elderly and the disabled because their burden on society would not be made up for by any production. Although the machines may seem to only fulfill the low skill jobs at the moment, there is no barrier to prevent the machines from replacing more. As the machines increase in intelligence, they will replace any tasks done by humans and render us unnecessary and worthless.

這個段落的主題句是The replacement of humans by machines leads to the loss of value to human life.機器代替人類將會使人的生命失去價值。之后運用因果論證方式來詳細展開，邏輯關系如下：

human tasks be performed by machines

comparisons between human and machine

a company will compare the two

people are evaluated not for their worth as human beings,

but for their effectiveness at performing a specific function

the worth of a person’s life depends on their capacity

person no reason to remain after serving their function

genocide against the elderly and the disabled
