A.模拟实验

B.调查法

C.实验法

D.观察法

答案

答案:B

观察法是在自然状态下,研究者按照一定的目的和计划,用自己的感官外加辅助工具,对客观事物进行系统的感知、考察和描述,以发现和验证科学结论.实验法是利用特定的器具和材料,通过有目的、有步骤的实验操作和观察、记录分析,发现或验证科学结论.在难以直接拿研究对象做实验时,有时用模型来做实验,或者模仿实验的某些条件进行实验,叫模拟实验. 调查一般是在自然的过程中进行的,通过访问、座谈、问卷、测验和查阅书面材料等方式去搜集反映研究对象的材料.调查时首先要明确调查目的和调查对象,制订合理的调查方案.调查过程中有时因为调查的范围很大,不可能逐个调查,就要选取一部分调查对象作为样本.调查过程中要如实记录.对调查的结果要进行整理和分析,有时要用数学方法进行统计.为掌握旱灾对粮食生产造成的损失,应采用的方法是调查法.
