标题: SDCAR2010【逻辑入门】(一)Arguments
【前言】

各位网友:
如果 CR 是你的弱项,如果你对 CR 发怵,那就请你关注我这个【逻辑入门】系列。无论你是考 GMAT 还是 LSATCR 都是关键一项。攻克 CR 是你考试成功的一个必要条件。而且掌握了 CR,你的英文写作也会变得条理分明,论据充分,结论恰到好处。但我这个系列有个前提:大部分只用英文。因为我的体会是:如果 CR 想考高分,你就得 Read, think, and analyze in English.
祝大家心想事成,求学顺利。

【逻辑入门】(一)Arguments

What is an argument?
An argument in logic is a set of one or more meaningful declarative sentences (or "propositions") known as the premises with another sentence known as the conclusion. Therefore, each argument has at least two components: 1) a piece of evidence orproposition, officially called a “premise,” and 2) a conclusion.

Consider the following two statements:
1)Ming Li is smart.
2)Ming Li went to Peking University.

Each statement by itself is simply a claim or an assertion. Can you combine them together to form an argument?

One answer might be:
Ming Li is smart because he went to Peking University.

The red part of the answer is the conclusion;the blue part of the answer is the premise.These color codes will be the convention I use to label premise and conclusion throughout the series.

A premise supports a conclusion. Most argument are not bullet-proof. That is: the evidence provided does not PROVE the conclusion reached beyond a shadow of a doubt. A premise is just an evidence, one reasonto shed some positive light on the conclusion, one piece of information which makes the conclusion more likely. In CR, all premises given in the stimulus are considered true. In the above example, we should not doubt whether Ming went to Peking University or not. However, we can analyze the argument by focusing on the logic which connects the premise and the conclusion in an argument.

Indicators

How to tell which statement is a premise or a conclusion in an argument? A quick way is to find indicators such asbecause, since, for, as, considering, whereas, and on the grounds that, which signal to the reader that a premise is coming! In the example above, Ming Li is smart because he went to Peking University, he went to PekingUniversity is the premise since this statement follows the word because.

A second way to form an argument using exactly the same statements is:
Because Ming Li is smart, hewent to Peking University.

This is a totally different argument from the first one in that the premise and the conclusion switch their places. Ming Li is smart is nowthe premise.

These two examples show that the order, in which each statement shows up in anargument, is less important than the logical relationship shown in the argument when deciphering which is the premise and which is the conclusion. Use theindicators to help you march through the puzzle in the beginning. The indicators for a conclusion might include: thus, therefore, accordingly, hence, in this way, consequently, and as a result.

What if there is no indicator in the argument?

In case you cannot find an indicator for premise/conclusion, you have to understand what the aruthor is trying to say and ask yourself which part is the conclusion and which part is the premise to support the conclusion. Considerthe following example:
Every milk product from Three Deers must be recalled. These products contain melamine which could lead to renal failure.

Which one is the conclusion? Which one is the premise? Most likely you wouldsay that  the 1st sentence is the conclusion and the 2nd sentence is thepremise.
Every milk product from Three Deers must be recalled. These products contain melamine which could lead to renal failure.

If in doubt, 1) simply connect the two sentences using the word because; and 2) see which one of the resulting arguments makes more sense:
1) Every milk product from Three Deers must be recalled because these products contain melamine which could lead to renal failure.
2) Becasue every milk product from Three Deers must be recalled, these products contain melamine which could lead to renal failure.

In CR test, if you can locate the premise and the conclusion of an argument,you have 50% chance of getting the right answer in the end. Train your eyes and brains to identify the conclusion of an argument quickly and precisely. Makesure your first step of a long march to the victory gets off on the right foot.

要继续写下去噢,我觉得姑且不算逻辑的各种题型到底用些什么方法,首先快速的把题干中的前提结论和假设提炼出来,再加上排除法,逻辑就能把握住很大部分,如果再辅佐运用些方法将更好,这是学习逻辑很好的途径。

我觉得这个东东比lawyer好,因为我属于那种对逻辑都还没有入门的,必须从根本上去了解逻辑。lawyer的方法可能对那种高级选手是直接受用的,对我这种菜鸟就不怎么奏效了。

For questions, such as "Which of the following can properly be inferred regarding the past above?" or "Which of the following conclusions can most properly be drawn from the information above?", how can we analyse an argument that without a conclusion?
作者: sdcar2010    时间: 2011-8-7 20:28
For the first question, it does not matter if there is a conclusion. More often than not, the passage just lists several facts or statements. Then the question stem (as you pointed out) simply ask for which of the following answer must be true based on the passage.

For the second question, the passage is most likely a few formal logic type of statement. So you have to treat the statements as premise or background info or evidence, then come up with a main conclusion.

For questions, such as "Which of the following can properly be inferred regarding the past above?" or "Which of the following conclusions can most properly be drawn from the information above?", how can we analyse an argument that without a conclusion?
