运用正确的推理方法

推理能力是逻辑思维能力的一种表现。推理就是从一个或几个已知的判断推出一个新判断的思维过程。要作出符合实际的判断，就要掌握正确的推理方法。演译推理和归纳推理是推理的两种主要形式。如：

Many people who have a cold also have a cough.So we can concludethat .

1. cold and cough may have some connection.

2. either cold causes cough or cough causes cold.

3. cold and cough go to get her.

4. cold and cough have the same cause.

利用归纳法，先分析“许多感冒的人也咳嗽”，由此我们不难推出“感冒和咳嗽可能有种联系”，故正确答案为 A。
